The study was conducted to evaluate the effect of Garcinia Kola (Bitter Kola) used as phytobiotic or herbal natural additives on biochemical and carcass characteristics of broiler chickens. Five diets with different levels of inclusion of the kola were fed to a total of 150 Marshal day- old broilers. There were three replicates of ten birds per replicate. The five diets were made of control diet; diets 2, 3, 4 and 5 had 500ppm, 1000ppm, 1500ppm and 2000ppm of G. Kola respectively. The feeding trial lasted for eight weeks. Data were analyzed using completely randomized design. The results of haematological parameters examined show that there were significant (P<0.05) differences in all the haematological indices measured, the values however, did not follow any particular pattern. Highest haemoglobin, packed cell volume (PCV) and red blood cells (RBC) values were recorded for birds on 1500ppm compared to other birds with values ranging between 8.40-10.00, 25.00-29.50 and 2.47- 2.77 for Hb, PCV and RBC respectively. The least haemoglobin and PCV values were recorded in diet containing 2000ppm. Dietary supplementation of G. kola revealed significant (P<0.05) effects in the values of albumin and serum aspartate aminotransferase (SAST) with fluctuating values. The albumin level increased from 0ppm to 1500ppm G. kola inclusion levels and later dropped at 2000ppm inclusion level. Birds fed bitter kola had higher values SAST than the control group. Results of carcass analysis study revealed significant (P<0.05) differences in the values obtained for live weight, dressed weight and dressing percentage. Birds fed with 0ppm of Garcinia kola had the highest live weight (2066.70g) while those on 1500ppm had the lowest. The same trend was observed in the mean values obtained for dressed weight. There were no significant differences (P>0.05) for all the organ weights observed except kidney which was found to show improvement with increased bitter kola level. It was concluded that dietary supplementation of broiler chicken with bitter kola produced haematological and carcass results that did not follow any definite pattern.

AbstractThree hundred young rabbits were divided into three groups at weaning and given ad libitum a control diet (C), or an experimental diet in which 0·20 of control diet was substituted by maize ear (E) or by whole maize plant (P) in order to examine their effects on fattening rabbits performance, carcass characteristics and meat quality. No significant differences were found in live-weight gain (45 g/day) or in food intake between diets but food conversion ratio was higher in the P group (2·4 g dry matter (DM) per g gain) than in E group (2·2 g DM per g gain). The rate of mortality was similar in the three groups. No differences between groups on live weight (2152 g) or in the digestive tract weight (437 g) were found and the dressing yield was similar in the three groups. At constant carcass weight, the carcasses of rabbits of the P group had lesser lumbar circumference and higher length to circumference ratio (P<0·0001) than of the C or E groups. No differences were found in the weights of liver or thoracic viscera, but kidneys of rabbits of P group were lighter than of the C or E groups. No differences between groups were found in the weights of scapular fat, perirenal fat, forelegs or thoracic cage, but the loin of rabbits of P group was heavier (291 v. 286 g) than in the other groups. Meat of rabbits P had higher L* and b* parameters of colour and higher water-holding capacity (P=0·003) but the meat of rabbits of the control group had less lipids (31 v. 36 g/kg meat) and more moisture (739 v. 735 g/kg meat) than of the experimental groups. The proportion of protein was higher in E group than in P group. Intra and intermuscular fat of hind leg meat from rabbits ‘maize’ substituted was more monounsaturated than control rabbits (34·2 v. 32·5 g·100 g lipids) and had lesser saturated: monounsaturated ratio (1·2 v. 1·3) indicating a more desirable meat from a nutritional point of view, but had less n-3 fatty acid content. Loin meat of the rabbits given E and P diets seems more tender than one fed conventionally (10·4 v. 11·4 kg) and meat of the rabbits ‘whole maize plant’ had more grass flavour (P=0·009) which is a positive factor for acceptability of consumers.

Feeding Trial

This study was carried out to evaluate the growth performance and carcass characteristics of finisher broiler chickens fed diet containing cooked cocoyam tubermeal as energy source in place of maize. The proximate composition of cooked cocoyam tubermeal showed that it contained 13.11% moisture, 2.60% ash, 3.90% crude protein, 9.45% crude fiber, 1.85% ether extract and 70.13% NFE. In the finisher feeding trial, the cooked cocoyam tubermeal was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each finisher diet was fed to a group of 30 finisher broiler chicken for 4 weeks using completely randomized design. Each treatment was divided into 3 replicates of 10 broiler chicks each. The birds were kept on deep litter and were given feed and water ad-libitum. Parameters measured include ifinal body weight, body weight gain feed intake, feed conversion ratio, carcass characteristics and economics of production. In the finisher feeding trial, the feed intake of the finisher broilers on diets 2, 3 and 4 were similar and compared favourably with those on the control diet. The finisher group on 100% CCYM (diet 5) recorded the lowest feed intake possibly because of the dustiness of the feed. The body weight gain of the finisher broilers on diet 2 (25%) cooked cocoyam tubermeal compared favourably with the control group and was significantly (P<0.05) higher than those on other diets. It appeared that the finisher broilers could not tolerate high levels of cooked cocoyam meal due to dustiness of the feed and its anti-nutritional factors. The cost of production per kg finisher broilers was cheapest for diet 5(100% CCYM) (N356.72) and the costliest was for diet 3(50% CCYM) (N588.28). The internal organs expressed as percent of the live weight were not affected by the treatments. In terms of carcass characteristics, the finisher broilers on diet 2(25% CCYM) recorded the highest breast muscle which was significantly different (P<0.05) from other groups. There were no significant different (P>0.05) on percent back cut, drumstick, head, shank, thigh, neck and wings of the finisher broilers on all the treatments. There were no significant differences (P > 0.05) in percent dressed weight of the finisher broilers on cooked cocoyam based diets. The results of the trial have shown that cooking cocoyam corms (Xanthosoma sagittifolium) for 30 minutes was effective for reducing the cyanide oxalate, tannin, phytic acid and saponin content and that cooking did not affect the proximate composition of tannia. Cooked cocoyam tubermeal could be used to replace maize up to 25% in the diet of finisher broiler chicken without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

L-carnitine as well as lysine and methionine are amino acids of important nutritional and nutraceutical interest and are used in nutritional strategies as dietary supplements to improve feed quality characteristics in animals and broiler chicken in particular. This study investigated the effect of different levels of L-carnitine and extra levels of lysine-methionine on growth performance, carcass characteristics, and some immune system markers. Two hundred seventy male Ross 308 broilers were a fed control diet (C) and eight different diets supplemented with an excess of amino acids. In the experimental diets, identified as D1, D2, D3, D4, D5, D6, D7, and D8, extra L-carnitine, lysine, and methionine were added in excess with respect to the American National Research Council (NRC) recommendations: L-carnitine equal to NRC (D1), control diet supplemented with lysine at 30% in excess of NRC, methionine at 30% in excess of NRC, and L-carnitine equal to NRC (D2), control diet supplemented with lysine equal to NRC, methionine equal to NRC, and L-carnitine at 15% in excess of NRC (D3), control diet supplemented control diet supplemented with lysine at 15% in excess of NRC, methionine at 15% in excess of NRC, and L-carnitine at 15% in excess of NRC (D4), control diet supplemented lysine at 30% in excess of NRC, methionine at 30% in excess of NRC, and L-carnitine at 15% in excess of NRC (D5), control diet supplemented with lysine equal to NRC recommendations, methionine equal to NRC recommendations, and L-carnitine at 75% in excess of NRC (D6), control diet supplemented with lysine at 15% in excess of NRC, methionine at 15% in excess of NRC, and L-carnitine at 75% in excess of NRC (D7), and control diet supplemented with lysine at 30% in excess of NRC, methionine at 30% in excess of NRC, and L-carnitine at 75% in excess of NRC (D8). During the starter and growth phases, feed intake was not affected by dietary treatment (p > 0.05). By contrast, body weight and FCR were both affected (p < 0.001) during the starter period. During the finisher phase, feed consumption was affected (p < 0.05) by dietary treatment. Feed intake of broilers fed on C, D3, D6, and D7 were statistically similar (p > 0.05) (1851.90, 1862.00, 1945.10, and 1872.80 g/pen/day, respectively) and were higher (p < 0.05) than 1564.40 g/pen/day (D5). With the exception of drumsticks, neck, back thoracic vertebrae, and proventriculus weights, the economical carcass segments were not affected (p > 0.05) by the dietary supplementation of amino acids. Duodenum and ileum weights and lengths decreased with amino acid supplementation (p < 0.05). IgT and IgG titers against Sheep Red Blood Cells (SRBC) for both primary and secondary responses were not affected by dietary treatments (p > 0.05). Dietary amino acids supplementation did not affect IgM titer after the secondary challenge (p > 0.05) and had a significant effect (p < 0.05) on serum antibody titers in broilers vaccinated against Newcastle disease (NCD) and Gumboro ‘s disease at the 27th and 30th days, respectively.

The objective of the study was to evaluate the effect of two methods of processing Bambara Groundnut Offal (BGO), toasted and enzyme supplemented in broiler chicken diets on haematology and carcass characteristics of broiler finisher chicken. One hundred and eight (108) four- weeks- old unsexed commercial broiler chicks were divided into three groups (T10% T220% T320%) of 36 birds, each replicated three times with 12 birds per replicate in a completely randomized design and fed for 28 days. Haematological parameters were not significantly (p>0.05) affected. Result of carcass characteristics showed that live weight, eviscerated weight, dressed weight, back weight, drumstick weight, breast weight, thigh weight and caecum weight were significantly (p<0.05) affected. Birds fed enzyme supplemented BGO diets recorded higher weights compared with birds fed toasted BGO and the control diets. Other carcass  characteristics such as wing weight, neck weight, head weight,  shank weight and other internal organ characteristics were not significantly (p>0.05) affected. From the result, significant parameters have shown that birds fed bioenzyme supplemented BGO diets were superior to birds fed toasted BGO and the control diet. It is therefore recommended that 2g/kg bioenzyme supplemented BGO diet should be used at 20% BGO inclusion rate for finishing broiler chicken without adverse effect on the haematology and for increased carcass weight.

AbstractOne hundred and thirty-two young rabbits were divided into two groups at weaning and given ad libitum a control diet (C), or an experimental diet (M) in which lucerne hay was substituted by mulberry leaves in order to examine their effects on fattening rabbit performance, carcass characteristics and meat quality.Digestibility coefficients of dry matter (DM), crude protein and gross energy were similar in both groups but digestibility of crude fibre in the experimental diet was higher in line with a lower food intake in this group of animals, while ether extract digestibility of mulberry leaves was very low.Food conversion ratio was similar in the two groups (3.1 g DM per g gain) but rabbits given the experimental diet had lower food intake (102 v. 144 g/day) and impaired live-weight gain. The rate of mortality was similar in the two groups. The substitution of lucerne with mulberry in the diet may have induced a higher retention time of digesta, as seems to be indicated by a higher weight of digestive tract contents recorded at slaughter (proportionately 0.32 more) in mulberry group. Live weight at slaughter of animals in control group was higher (2680 v. 2211 g) and also skin weight was proportionately 0.5 higher and its carcasses were proportionately 0.41 heavier than those of animals in experimental group (dressing yield 587 v. 503 g/kg). At constant carcass weight, the carcasses of rabbits of the mulberry group were longer than the lucerne group, but lumbar circumference tended also to be higher (P = 0.09) and no differences were found in the length: circumference ratio. No differences were found in the weights of kidneys or thoracic viscera, but livers of rabbits of the lucerne group were heavier (proportionately 0.3 heavier). The more remarkable difference was that carcasses of rabbits given the experimental diet had markedly less fat in scapular (5.8 v. 10.0 g) and perirenal fat (9.0 v. 22.3 g) deposits.No differences in cooking losses or water-holding capacity of the meat were found and also the colour was similar, but the b* parameter was a little lower for meat of the M group rabbits.The proportion of protein in the meat was the same for rabbits of the two groups, but rabbits given the experimental diet which had leaner carcasses also had leaner meat (19 v. 37 g lipids per kg meat) and a little more moisture (755 v. 736 g/kg meat). Intra and intermuscular fat of hindleg meat from rabbits of group M was less saturated and more unsaturated than that of the conventional rabbits mainly due to its higher proportion of polyunsaturated fatty acids, ω6 (37·3 v. 29·1 g/100 g lipids) and ω3 (3·4 v. 2·2 g/ 100 g lipids). Polyunsaturated: saturated ratio was higher in the mulberry group than in the lucerne group (1·15 v. 0·85) indicating a more desirable value in rabbits given the experimental diet, so meat of these rabbits could be considered preferable for human nutrition from this point of view.

Growth performance, carcass characteristics and economics of broiler chicken fed graded levels of raw Mucuna sloanei seed meal were investigated. A total of 150, 1- day old broiler chickens were used. There were five treatments each replicated into three with 10 birds per replicate in a completely randomized design. Five treatment diets were formulated. Diet 1served as control, while diets 2, 3, 4, and 5 had 5, 10, 15, and 20 %, respectively of raw mucuna seed meals (RMSM) added to them. The experiment lasted 49 days. The parameters considered were growth performance, carcass characteristics and economics of production. For growth performance, the result revealed that RMSM significantly (P<0.05) depressed growth as the levels of inclusion of RMSM increased from 0 to 20%. There were significant differences (p<0.05) in all the parameters considered under growth except for initial body weight and mortality. There was progressive loss in final body weight as the level of mucuna inclusion increased from 0% to 20%. Control recorded the highest live body weight of 3023.30g while, birds fed diet with 20% mucuna had the least body weight of 504.43g. Among the birds placed on the test diets, birds fed diet with 5% mucuna seed meal performed significantly (P<0.05) better (1840.00g) than other test diets. Birds fed diets with 10 and 15% mucuna had final body weight of 1180.00 and 726.67g, respectively. The progressive l oss in weight was obvious early in the experiment and at 8 weeks of age the broiler fed 20% raw mucuna. Mucuna sloanei based diet weighed only 504.43g (16.68% of the control) as against 1840.00, (60.86% of the control) for that fed 5%.mucuna. Percentage dressed weight and percentage breast and thigh were significantly (P<0.05) higher for chicken fed control diet. 10% level of raw MSSM gave highest value for drumstick (14.91%) while control gave the least (13.00%). 5% raw MSSM (27. 71%) compared favourably with control (30.60%) for breast cut. Gross margin significantly decreased from N1459.80 for control diet to N 14.20 for D5 as the percentage inclusion of MSSM increases from 0 to 20%. In conclusion, birds fed raw Mucuna sloanei seed meal diet could not compare favourably with those fed soya bean based diets even at 5% level of inclusion. Processing is therefore recommended to enhance performance.

Целью исследований явилось изучение живой массы и среднесуточных привесов цыплят-бройлеров кросса «Hubbard» при введении в питьевую воду препарата фульвиокислоты компании BioSap Technologies. Птицы контрольной и опытных групп получали в период выращивания одинаковый рацион (полнорационные комбикорма престарт, старт-1, старт-2, рост, финиш) в соответствии с возрастом. Птицы трех опытных групп дополнительно получали в питьевой воде 2, 4 и 6% препарата фульвиокислоты, произведенного из сапропеля озера Жарки Тверской области. К моменту забоя в 40-дневном возрасте наилучший результат по живой массе – 2592,97 г – получен в опытной группе 2 (4% препарата), птицы которой достоверно превосходили бройлеров опытной группы 3 (6% препарата) на 203,31 г или на 8,51% (p<0,01). У курочек опытной группы 2 показатель составил 2475,53 г, что достоверно больше по сравнению с курочками опытной группы 3 на 245,53 г, или на 11,01% (p<0,01). Цыплята-бройлеры опытных групп 1 и 2 превосходили по живой массе птиц контрольной группы, у петушков это характерно и для опытной группы 3. Наилучшие результаты по среднесуточному приросту отмечены также в опытной группе 2. Без учета пола результат составил 63,82 г, что достоверно больше по сравнению с показателем опытной группы 3 на 5,05 г, или на 8,59% (p<0,05). Среднесуточный прирост курочек опытной группы 2 равен 60,88 г, что на 6,09 г или на 11,12% больше по сравнению с курочками опытной группы 3 (p<0,01). Цыплята-бройлеры опытной группы 3 без учета пола, а также курочки уступают по этому показателю птицам контрольной группы. Оптимальной дозой дачи препарата BioSap Fulvic Power компании BioSap Technologies цыплятам-бройлерам следует считать добавление 4% в питьевую воду. The research goal was to learn how the live weight and average daily weight gains of «Hubbard» cross broiler chickens change when their drinking water is added with a fulvic acid preparation produced by the BioSap Technologies company. Birds of both the control and experimental groups were fed in the raising period the similar feeding rations (complete-value combined feeds of pre-start, start-1, start-2, growth, finishing) depending on the growth stage of chickens. The birds in the experimental groups were fed additionally 2, 4 и 6% fulvic acid preparations produced from the sapropel of the Tver oblast Zharki lake .By the slaughter time, at the age of 40 days, the best live weight results of 2592,97 grammes were shown by experimental group 2 fed with a 4% preparation, which reliably exceeded the weight of group 3 chickens (6% preparation) by 203,31 grammes, or by 8,51% (p<0,01). With female chickens in group 2 the value was 2475,53 grammes, which reliably exceeded the weight of group 3 chickens by 245,53 grammes, or by 11,01% (p<0,01) Broiler chickens of experimental groups 1 and 2 exceeded the control group, the same was noted with male chickens ot experimental group 2 too. The best results in average daily gain were also recorded in experimental group 2. Sex differences not being considered, the result was 63,82 grammes, which reliably exceeded the weight of group 3 chickens by 5,05 grammes, or by 8,59% (p<0,05). Daily gains of female chickens in experimental group 2 were 60,88 grammes, or 6,09 grammes higher than those in experimental group 3 (11,12%). Broiler-chicken values of experimental group 3, sex not being considered, as well as female chicken gains were lower than those of the control group. The optimum dose of the BioSap Fulvic Power preparation produced by the BioSap Technologies company should be considered that of 4% added into drinking water.

Aims: An experiment was conducted to investigate the comparative efficacy of two probiotics of different origins (yeast and bacterial based) on the growth performance and carcass characteristics of broilers chicken. Place and Duration of Study: The study was conducted at Krishi Vigyan Kendra, Purnea between January, 2020 to March, 2020. Methods: Two hundred and forty, day old chicks were kept and were randomly divided into 4 groups (A, B, C and D) and each group had 2 replicates of 20 chicks. Four (A, B, C and D) iso-caloric and iso-nitrogenous (ME 3000 kcal/ kg and CP 21.56%) broiler starter and finisher (ME 3000 kcal/ kg and CP 18.75%) diets were formulated containing Saccharomyces cerevisiae, Bacillus cereus toyoi and mixture of both @ 0.2% except group A which was control. Birds were raised for first week on commercial diet. Broiler starter and finisher diets were fed from 8-28 and 29-42 days, respectively. Results: A significant (P<0.05) effect was observed on overall performance of the birds fed diet containing probiotics. Probiotics in feed at 0.2% Saccharomyces cerevisiae supplementation improved body weight gain (+12.7%), feed intake (3.8%) and feed conversion efficiency (-8.7%) compared with the control diet. Among groups, no significant differences were observed in carcass traits but highest dressing percentage was recorded in group-B followed by group-C than group-D and lowest in control group. Conclusion: The result indicated that the addition of probiotics in feed containing 0.2% Saccharomyces cerevisiae improved broiler growth performances and it is beneficial to be used as supplement in feed of broiler chickens.

An experiment with 25 growing goats (in 5 groups) were fed four different tree forage based diets (B,C,D,E) and control A showed that there were significant (p<0.05) differences in DM , ME and DCP intakes. Although there were no significant differences in the digestibility of DM, OM, CP and ADF but intake of these nutrients were significantly (p<0.05) differed among the treatments. There were no significant differences in the digestibility of diets having different forages but they were significantly higher than that of grass based control diet. Feeding of tree forages had significant (p<0.05) effect on live weight gain of goats. Animals fed tree forage based diets significantly (p<0.05) increased weight gain (60.03, 59.10, 57.75 and 55.57 g/d for Sesbania grandiflora, Leucaena leucocephala, Erythrina orientalis and Morus alba, respectively) compared to that of control group (39.25 g/d) . However, there were no significant differences in weight gain of the animals fed different tree forage based diets. Feed conversion efficiency (kg feed/kg gain) also showed that animals fed tree forage based diets presented significantly (p<0.01) higher efficiency (11.74, 12.05, 12.21 and 12.02) for L. leucocephala, E. orientalis, S. grandiflora and M. alba compared to that (16.00) of fed control diet. Nitrogen balance trial showed that there were significant (p<0.05) differences among the mean values in terms of total N intake (g/d), nitrogen retention (%) and nitrogen balance (g/d). It may be concluded that supplementation of diets with tree forages resulted in better weight gain, digestibility and nitrogen balance compared to green grass. So, the diets of goats may be supplemented with tree forages of S. grandiflora, L. leucocephala, E. orientalis and M. alba for improved growth performance.Asian J. Med. Biol. Res.

Randomized Design

A total of one hundred and twenty (120) day old chicks were carried out in a Completely Randomized Design to compare the intestinal villi height, villi width and crypt depth of broiler chicken fed with centrosema ( C. pubescens) leaf meal  at dietary levels of 0, 2, 4 and 6% respectively. The results showed that broiler’s duodenal villi height was longest for broilers without leaf meal (T1) 1738.69 µm and the shortest for the broilers supplemented with  6 % C. pubescens leaf meal (T4) 883.10 µm. Duodenum villi width in broilers Treatment 4 had the longer and wider intestinal segments than those broilers in T2. Crypth depth of T2 were not significantly deeper (838.55 µm) over those broilers in Treatment 3 and 4 and the control group (T1). Jejunal villi height of the broilers supplemented with 2 % C. pubescens leaf meal had the longest villi height in T2 (1195.79 µm) and the shortest was measured on T4 (912.05 µm). Treatment 3 broilers had wider jejuna villous over those broilers in Treatments 4, 2 and 1 respectively. The jejunal crypt depth were deepest on T2 (362.45 µm) and the shallowest was recorded on T4 broilers with 255.82 µm. T1 the control group had the tallest ileum villi height over those broiler treated or supplemented with C. pubescens leaf meal. Broilers in T3 had wider ileum villous with 109.46 µm while narrower villi width was observed in T2 broilers with 66.86 µm. Treatment 3 were the deepest ileum crypth depth with 362.40 µm and the shallowest was measured on (T4) (259.23 µm). The inclusion of the different levels of centrosema leaf meal (CLM) did not influenced the growth performance of broiler, however the supplementation of centrosema leaf meal (CLM) on the diet tend to increased body weight of the broiler chicken with the highest rates at T3. The effect of dietary supplementation on the intestinal villi of broilers did not show any variation in terms of the villi height, villi width and crypt depth and results were in congruence with the result of growth rate, feed conversion efficiency and feed conversion ratio. The dietary supplementation of C. pubescens in broiler chicken rations can be add as protein supplement in broilers diet although not significantly different with the use of commercial feeds, addition of CLM in the ration can be advantageous in minimizing production cost.  It is recommended to conduct further studies using higher levels C. pubescens and also the use of colored broiler chickens.
