The effect of the mannan-oligosaccharide Bio-Mos on broiler chicken performance, after its incorporation in the starter diet was evaluated. A total of 53,040 one day-old Cobb chicks, randomly divided into two groups with four replicates each, were used in a feeding trial that lasted 40 days. One of the groups (Control group) was fed on a basal commercial starter diet, while the other (Bio-Mos group) was given up to day 10 of age the same diet supplemented with the mannan-oligosaccharide Bio-Mos at the level of 1.5 g/kg of feed. From day 11 of age and thereafter, Bio-Mos administration was discontinued and both groups were given the same basal commercial grower and finisher diets. Results showed that chickens in the Bio-Mos fed group exhibited a significant (P<0.05) improvement in body weight compared to control at day 10 (295 vs 254 g) and day 40 (2108 vs 2017 g) of age. Feed intake per bird from day-old to day 40 of age showed a significant (P<0.05) increase in the Bio-Mos group compared to control (3647 vs 3612 g), whereas feed conversion ratios also demonstrated a significant (P<0.05) improvement for the Bio-Mos group (1.73 vs 1.79). Mortality rate was lower in the Bio-Mos group compared to control (2.5 vs 2.9%), however, the difference was not statistically (P>0.05) significant.

The objective of our study was to test amaranth grain or dried biomass in the diet for broiler chickens as a resource of protein replacing animal protein. Further, the effect of amaranth on broiler performance, carcass characteristics and meat quality were assessed in a feeding trial. The experimental groups of broilers were fed feed mixtures with crude amaranth grain (AC), heat processed amaranth grain (AP) or dried above-ground biomass (AB). Control groups (C) received the diet containing animal proteins. The results obtained in the experimental groups of broiler chickens can be compared to the control group in all the production indicators under investigation. On day 42 of the experiment, live weight (g) of female broilers ranged from 2 205.1 &plusmn; 152.5 (AP) to 2 254.0 &plusmn; 136.5 (C), and that of male broilers from 2 375.1 &plusmn; 233.0 (AC) to 2 506.0 &plusmn; 286.0 (C). Feed conversion ranged from 1.80 kg in control group of male broiler chickens to 1.91 kg in experimental group of male broilers (AB). Percentage yield in female broiler chickens ranged from 70.8 &plusmn; 1.74 (AB) to 72.4 &plusmn;3.34(AC) or 72.4 &plusmn; 1.98 (C), and in male broilers from 72.8 &plusmn;3.55(AP) to 75.1 &plusmn;2.44(AB). Our results showed that amaranth can fully replace meat-and-bone meals in the diets for broiler chickens.

Broiler chicken diets were diluted with three levels of whole wheat and two levels of crumbled wheat to determine how feeding whole grain and diluting feed with wheat would alter the performance of male and female broilers. Grit was not used. The amount of extra wheat added increased from 5% at 11 d of age to a maximum level of 30% at 31 d of age. Body weight at 41 d of age averaged 2.130 kg for pullets and 2.422 kg for cockerels and was unaffected by diluting with wheat, in whole or crumbled form. Total mortality and cause of mortality were similarly unaffected by dilution and form of wheat. The feed:gain ratio from 11 to 41 d of age was increased significantly for cockerels from 1.75 at zero dilution to 1.84 at maximum dilution. Dilution did not affect the feed conversion of pullets and form did not influence the feed conversion of either sex. Dilution of broiler rations may be profitable because of the limited effect on bird performance. Pelleting all the wheat in poultry rations is unnecessary because bird performance is unaffected by feeding up to 30% whole grain in the finisher diets.

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.

The main objective of this research was to verify the effect of feed mixtures supplemented with clinoptilolite-containing ZeoFeed (at a level of 1% and 2%) on the performance traits of broiler chickens in the period of their growth. Experimental results confirmed a positive effect of clinoptilolite on the performance of chickens which was demonstrated by a highly significant increase in the average live weight (P &le; 0.01) of broiler chickens at 40 days of age. The average live weight of broiler chickens was 2.24 kg (at a dose of 1%) and 2.28 kg (at a dose of 2%) with feed conversion of 1.84 kg (at a dose of 1%) and 1.95 kg (at a dose of 2%) while the average live weight of control broiler chickens was 2.12 kg with feed conversion of 1.83 kg. No differences between both groups were found in water consumption. Chickens in all monitored groups showed very good health and a very low rate of mortality (3.75% in control group, 1.25% at a dose of 1% and 3.75% at a dose of 2%). It follows from the experiments that the clinoptilolite-containing product may serve as a suitable feed supplement to feed mixtures for broiler chickens. &nbsp;

A study was carried out to look at the utilization of cowpea based diets on performance characteristics and haematology of broiler chickens.  Raw cowpea, dehulled cowpea, dehulled cooked cowpea and dehulled roasted cowpea grains were fed to broiler chickens in an eight week feeding trial. A total of two hundred (200) day old unsexed broiler chicks of Marshall strain were allotted into five dietary treatments.?Feed intake and growth were significantly (P < 0.05) reduced in birds fed raw cowpea and dehulled cowpea respectively. The feed conversion efficiency (FCE) and protein efficiency ratio (PER)  also followed a similar pattern. Non significant (P > 0.05) differences were however obtained in weight gain, FCE and PER of birds fed control diet and those fed dehulled cooked cowpea in this study. Birds fed dehulled roasted cowpea also had marginal reductions in weight gain, FCE and PER when compared to those fed dehulled cooked cowpea based diet. The haematological studies showed lower (P < 0.05) values of haemoglobin, red blood cells, packed cell volume and white blood cells of birds fed raw cowpea and dehulled cowpea respectively. The best significant indices in this study were however obtained in birds fed dehulled cooked cowpea.Bang. J. Anim. Sci. 2016. 45 (1): 62-68

The objective of this study was to verify the possibility of replacing soybean oil in a diet with glycerol, and investigate the effect of glycerol on performance indicators and health in broiler chickens. The experiment was performed on 122 one-day-old chickens that were divided based on sex into two control groups (30 females and 31 males) and two experimental groups (30 females and 31 males). Half (50%) of the soybean oil in diets used in the experimental groups was replaced with glycerol at a ratio of 1:2. On 15, 32 and 38 day of age chickens of both sexes in the experimental group that were fed with diets containing glycerol showed significantly higher (p ≤ 0.01) mean body weight compared to the control group. At the end of the experiment, the mean weight of chickens in the control group was 2.078 kg, whereas the mean weight of chickens in the experimental group was 2.341 kg. In females, the overall consumption of diets within 38 days of fattening was 3.588 kg in the control group and 4.011 kg in the experimental group, in males, it was 3.915 kg in the control group and 4.366 kg in the experimental group, i.e. it was higher in experimental chickens. Feed conversion in chickens in experimental groups was better, being 1.84 kg in the control group and 1.81 kg in the experimental group in females, and 1.73 kg in the control group and 1.72 kg in the experimental group in males. It follows from our results that the optimum amount of glycerol in feed for poultry is 5%.This study presents an original solution to optimize feed formula by replacing plant oil with glycerol. The results of the study can improve production indicators and economy in broiler fattening.

AbstractThe purpose of this paper was to assess the suitability of various protein feeds in broiler chicken feeding. The study covered 160 birds split into 5 equipotent groups (SBM, EFFS, RFFS, EL, DDGS). Four protein feeds were an experimental factor: extruded full-fat soybean (EFFS group), raw full-fat soybean (RFFS group), extruded lupine (EL group) and distillers dried grains with solubles (DDGS group) that were added to starter rations in an amount replacing 30%, and in grower and finisher rations 50% of extracted soybean meal protein. Results showed that after replacing an identical amount of extracted soybean meal protein with protein from extruded soybean or DDGS in chicken rations, the final body weight and feed conversion ratio were similar to those of birds from the control group. Deterioration (P≤0.01) in the above-mentioned parameters was observed for chickens fed with rations containing raw soybean or extruded lupine. Birds that were given rations containing raw soybean (RFFS group) were characterized by the lowest dressing percentage, and, compared to the control group, the difference was significant (P≤0.01). The type of protein feed contained in the rations did not affect the musculature of chickens, however it did impact their fat deposition. Fat deposition was the lowest in birds from RFFS and DDGS groups that reached the lowest final body weight. Microscopic images of all examined livers showed a normal histological structure. The results of the studies carried out provide a basis for recommending the use of extruded full-fat soybean or DDGS in broiler chicken rations as partial substitutes for extracted soybean meal protein.

Probiotics colonize the intestine of animals and birds and provide useful effects on their performance and immune status. This study describes a high throughput screening and characterization of spore-forming bacteria from Iranian poultry farms with the aim to identify potential probiotic native Bacillus spp. and determine its effects on growth performance, hemato-biochemical parameters, immunity, intestinal microflora, morphology and MUC2 gene expression of broiler chickens. A total of 300 one-day-old female Ross 308 broilers (42.6 ± 0.6 g) were used in a 6-wk study. Broilers were randomly allotted to 1 of 3 dietary treatments consisting of 4 replicate cages with 25 broilers each: 1- Control (Corn-soy-based diet: C), 2- C + 200 g/ton of the GalliPro® (Bacillus subtilis DSM 17299, 4×109 CFU/g, as positive control group: PC), 3- C + 200 g/ton of the native probiotic (B. tequilensis K03, 4×109 CFU/g: NP) identified in this study. During the experiment parameters were measured weekly. The results revealed that birds of the NP and PC groups exhibited improved feed conversion ratio (FCR) and increased body weight (BW), carcass and breast meat yield compared with the birds of the C group (P<0.05). Also, lymphocytes level, antibody titers against Newcastle diseases virus (NDV) and infectious bronchitis virus (IBV) of vaccinated birds were increased, while serum triglycerides, total cholesterol levels and abdominal fat of birds fed NP and PC were decreased compared to birds of the C group (P<0.05). The villus height, the relative expression of MUC2 gene and Bacillus spp. populations were increased, while E. coli was significantly decreased in the ileum content of treated groups (P<0.05). These results indicate that the identified native B.tequilensis K03 strain can improve immunity and broiler performance by modifying intestinal microflora and morphology. Studied native probiotic Bacillus tequilensis K03 has useful effects on health status and it can be used as poultry feed supplement.

This study examined the effect of Mucuna seed powder (MSP) supplementation on performance, meat, and health status of broiler chickens. A total of 300 broiler chicks were randomly allocated into 5 treatments with 6 replicates of 10 birds each, as follows: Diet 1 (control), Diet 2 (diet supplemented with 1.1% oxytetracycline, OXYT), Diet 3 (diet with 0.5% MSP), Diet 4 (diet with 1.0% MSP) and Diet 5 (diet with 1.5% MSP). The dietary MSP supplementation significantly (P<0.05) increased the daily body weight gain of the broiler chickens, compared to those fed the control diet at the starter phase and overall (1-42 days) period of the feeding trial. No significant differences were observed in the measured aspartate aminotransferase (AST), creatinine, and alanine aminotransferase (ALT) among the treatments. The broiler chicken fed diets supplemented with MSP had higher (P<0.05) total serum glutathione peroxidase and superoxide dismutase compared to those fed the control diet. The concentration of muscle cholesterol and lipid peroxidation reduced significantly (P<0.05) in the birds fed MSP supplemented diets compared to those fed the control diet. In conclusion, this study has shown that MSP can be used up to 1.5% as a potential phytogenic feed supplement in a broiler diet to enhance the growth performance, maintain the carcass traits, boost endogenous antioxidants and reduce meat cholesterol level and lipid oxidation.

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.
