A comparative study was carried out on three breeds of snails in South Eastern Nigeria to assess their growth performance and body morphology. The three breeds used were A. Fulica, A. achatina and A. marginata. Four experimental diets were formulated to contain Concentrate + Pawpaw (Diet I), Concentrate + Moringa oleifera (Diet II), Concentrate + Moringa oleifera + African spinach + Amaranthus hybridus (Diet III) and Concentrate + Moringa oleifera + Amaranthus spinosus (Diet IV). Fifteen 6-month old growing snails of each breed were assigned per dietary treatment and each dietary treatment was replicated three times to contain five snails per replicate, given a total of one hundred and eighty snails. The experiment involved a 3 x 4 factorial experiment in a Completely Randomized Design (CRD). Feed and water were given ad libitum throughout the duration of the experiment which lasted (56 days). Parameters measured were body parameters which include body weight, body width, body length, aperture length and aperture width; growth performance parameters obtained were initial weight, final weight, average weekly weight gain, average weekly feed intake and feed conversion ratio. The results showed that the A. achatina and A. marginata similarly recorded higher values in body parameters than the A. fulica. The A. marginata however was longer (12.69 cm) than the 8.95 and 12.32 cm recorded for A. fulica and A. marginata gain was only influenced by interaction effect of the breed x diet. The A. marginata and A. fulica revealed higher foot weight 58.81% and 57.59% respectively in relation to their live weight, which was associated with lower % shell weight (17.17 and 22.33% respectively), whereas, the higher shell weight (36.18%). The highest foot weight (57.50%) was observed in snails fed diet I, associated with relatively high live weight and highly reduced offal weight, which makes it comparatively better in improving carcass. Based on overall interaction effects, diet I is recommended for A. fulica, while diet III for A. marginata and diet II for A. marginata. The A. marginata performed better than the A. achatina and A. fulica in body size (body length) and foot weight, thus  recommended.

A comparative study was carried out on three breeds of snails in southeastern Nigeria to assess their carcass characteristic and carcass nutrient compositions. The three breeds used were Achatina fulica, Achatina achatina and Archachatina marginata. Four experimental diets were formulated to contain concentrate + pawpaw (Diet I), concentrate + Moringa oleifera (Diet II), concentrate + Moringa oleifera+ African spinach + Amaranthus hybridus (Diet III) and concentrate + Moringa oleifera+Amaranthus spinosus (Diet IV). Fifteen 6-month old growing snails of each breed was assigned per dietary treatment and each dietary treatment was replicated three times to contain five snails per replicate, given a total of one hundred and eighty snails. The experiment involved a 3 x 4 factorial experiment in a completely randomized design (CRD). Feed and water were given ad libitum throughout the duration of the experiment which lasted (56 days). At the end of the experiment, a total of seventy-two (72) snails were starved and slaughtered for carcass evaluation. Carcass nutrient compositions were measured including dry matter, moisture content, ash, crude fibre, crude protein, fat and nitrogen free extract. The results showed that the highest foot weight (57.50%) was observed in snails fed diet I, associated with relatively high live weight and highly reduced offal weight, which makes it comparatively better in improving carcass. The A. fulica, A achatina and A. marginata obtained best carcass composition respectively on diets I, III and II due to interaction effect of breed x diet. The A. achatina and A. marginata had higher dry matter (91.64 and 92.07 respectively) than the A fulica (90.09). The A. marginata carcass had the higher (p<0.05) crude protein (32.78%), highest ash (9.17%) and a moderate fat content (1.59%). Based on overall interaction effects, diet I is recommended for A. fulica, while diet III for A. marginata and diet II for A. marginata. The A. marginata performed better than the A. achatina and A. fulica in highest crude protein, highest ash and a moderate fat content and is thus recommended.

The purposes of determining the influence of the light and sexing on growth performance and slaughter results atyoung quails from Balotesti population, was organized an experiment on 150 quails, betwen age of 28 and 70 days. The chicks were divided into two groups (control and experimental), and growth and slaughter performance were determined separately by sex. Have studied 2 lighting programs, a program of continous lighting with photoperiod duration of 16 hours (16 L + 8 N, control group) and a program with lighting with asymetric hours intervals with photoperiod duration of 16 hours (10L+2N+6L+6N, experimental group).Males and females from the experimental group were recorded average performance of growth high during the period 28 - 70 days. Live weight at age of 70 days was higher with 7.54 %, average weight gain was higher with 14.86 % and feed conversion rate was lower with 13.51 % at males from experimental group compared to males from the control group. Also, the live weight at the age of 70 days was higher with 18.09 %; average weight gain was higher with 35.12 %, while feed conversion rate was reduced with 30.08 % on females from the experimental group compared to females from the control group.The results of the slaughter at 70 days were superior in the caseof females from the both groups versus males. The average weight of the carcase was higher with 17.53 % in case of the females than that of males from the experimental group, and the carcase yield was 65.37 % at the females and 65.56 % for males. Also, the average weight of the carcase was higher with 5.08 % in case of females compared to that males from the control group, and the carcase yield was 64.20 % to females 66.70 % on males.Superior results recorded in the case of females and males from the experimental group recommended the program of lighting with asymmetric hours intervals in the growth of youth quail. Also, the higher slaughter results recorded in the case of females of the two groups recommended them in the meat production through a broiler of quail that combine advantages in the production of both males and females.

Abstract(An experiment with two groups of East Balkan pigs – castrated males (n=10) and females (n=10), was carried out to study the growth performance and fattening abilities of the animals from the weaning until slaughter. The pigs were included in the trial at 60 day age. The average live weight of the castrated males was 8. 65±1.08 kg and for the females, 8.5±0.62 kg.The pigs were reared using traditional technology, grazing on natural pastures in the Strandzha mountain, Bulgaria. In autumn, acorns were naturally present in their diet. According to the category, the animals additionally received ground organic feed (50% barley and 50% wheat). The trial lasted 304 days (from February to November, 2019). During this period the final live weight of the male castrated pigs reached 88.00 kg while that of the females was 84.4 kg. The difference, however, was not significant. Furthermore, no significant differences in the growth performance characteristics that could be attributed to the sex of the animals were observed. The average daily gain of both sexes tended to be lower in summer and higher in autumn. The feed conversion ratio was higher in summer. The animals showed high average daily weight gain at pasture when their live weight was over 50 kg.

Background: Fat and oil are commonly used in poultry diets to increase energy density and also to increase the palatability of feed, feed efficiency and for deposition of fat in broilers. Thus a study was proposed to find the effects of dietary replacement of saturated fatty acid rich palm oil (PO) by omega-3 rich rapeseed oil (RO) on growth performance and economics in broilers. Method: The growth performance feeding trial was conducted in 160 day-old broilers (vencobb 400) with four treatment groups (G1, G2, G3 and G4) with four replicates of ten chicks each. The basal diet (R1) was prepared with palm oil included at the rate of 1.5, 3, and 4.5 per cent in pre-starter, starter and finisher ration, respectively and fed to G1. The other treatment groups G2, G3 and G4 received R2, R3 and R4 experimental rations respectively. The experimental rations R2, R3 and R4 were prepared with rapeseed oil replacing 25, 50 and 100 per cent of palm oil which was included in R1. Result: The broiler ration prepared with rapeseed oil at 50 and 100 per cent level (G3 and G4) replacing palm oil showed increased body weight gain (P less than 0.01) and better feed conversion ratio (P less than 0.05) than G1 group. There was no significant difference in the feed intake among the different treatment groups. Profit per kg live weight in G3 (Rs.12.06) and G4 (Rs.11.14) was more than G1 (Rs.8.21) and G2 (Rs.6.57). The supplementation of omega-3 rich rapeseed oil had significantly improved the performance of broilers.

Abstract This experiment evaluated varying levels of Amarula (Sclerocarya birrea A. Rich) nut cake (ANC) on growth performance, nutrient digestibility and carcass characteristics in pigs. Thirty Large White × Landrace (LW × LR) pigs were stratified by weight (average live weight of 20 ± 5 kg) and randomly allocated to the five experimental diets that contained 0 (control), 50, 100, 150 and 200 g ANC/kg DM. Each pig served as a replicate unit, housed individually. Bodyweight, feed intake, average daily gain (ADG) and feed conversion ratio (FCR) were recorded weekly throughout the trial period. On completion of the growth trial, following a 3-day adaptation, a nutrient digestibility study was conducted over 5 days. Thereafter, pigs were fasted for twelve hours, weighed, slaughtered, and carcass samples were collected for analysis. Feed intake was not affected by dietary treatment, but ADGs were reduced at ANC levels > 15%, resulting in poor FCR. Protein digestibility was reduced at ANC levels > 15%, while ether extract and fibre levels increased. Warm and cold carcass weights were lower at ANC levels > 15, with improved meat redness and lightness. It was concluded that ANC could replace SBM in the diet of growing pigs at less than 15% inclusion level.

A total of 324 local pullet chicks (1- 8 weeks) were used for the research project to evaluate the feeding value of raw and boiled pigeon pea seed meal (PSM) on their growth performance. Nine iso-caloric and isonitrogenous diets were formulated, with raw and boiled pigeon pea seed meal at inclusion levels of 0%, 15%, 20%, 25% and 30%, respectively. There were 36 chicks per treatment replicated into 3 at 12 chicks per replicate. There were significant interactions between form and PSM levels on the final live weight, daily feed intake and daily protein intake. Final live weight of pullets fed both raw and boiled PSM followed the same trend, pullets fed control (0%) and 15% raw PSM 128.10 and 132.33g respectively performed better than the rest of the treatment levels but statistically similar at all levels. Daily feed intake and daily protein intake showed significant interaction among the treatments. Pullets fed control (8.95g) and raw diets (8.79g) consumed more feed than pullets fed boiled PSM II (105.05g), III (117.77g) IV (91.27g) and V (112.80g) diets. Daily weight gain, feed conversion ratio and protein efficiency ratio had no significant (P>0.05) interaction between form and treatment groups for the pullets. 30% PSM raw or boiled can be fed to local pullet chicks without any deleterious effect on the growth performance.

A study was conducted at the Abubakar Tafawa Balewa University (ATBU) Research and Teaching Farm between December and May 2006 to determine nutrient intake, digestibility and growth performance in Yankasa rams fed urea-treated (UTRS) and untreated rice straw (URS) with supplementation. Thirty-two (32) Yankasa rams with an average weigh of 17.5kg, and aged 1.5 to 2 years old were alloted to eight (8) dietary treatments with four (4) rams per treatment in a 2 x 4 factorial design. The two basal feeds were urea0treated rice straw (UTRS) and untreated rice straw (URS). The supplements were maize bran (MB), MB + sun-dried poultry litter (MB + SDPL), MB + ensiled poultry litter (MB+ EPL) and MB + cotton seed cake (MB + CSC). Total dry matter intake (TDMI), daily basal feed intake (DBFI) were significant (P<0.05) across dietary treatments. Animals on supplements MB and MB+CSC for both UTRS and URS recorded the lowest and highest DBFI. The digestible crude protein intake (DCPI) and digestible organic matter intake (DOMI) were high for rams on UTRS and the values ranged from 17.72 to 28.36g/d and 288.81 to 482.66g/d for DCPI and DOMI respectively. Nutrient digestibility was improved by treatment of straw and supplementation. However, crude protein digestibility was similar for animals fed URS but, significantly (P<0.05) lower compared to those fed UTRS which were also similar across supplements. Average daily weight gain ranged from 53.58 to 91.18g/d across dietary treatment with animals on supplement MB recording the lowest (53.58 and 61.43g/d for URS and UTRs respectively) and those fed supplement MB+CSC the highest (81.38 and 91.18g/d fro URS and UTRS respectively) irrespective of straw treatment. Feed conversion ratio (FCR) was least for animals on supplement MB+CSC for both URS and UTRs, indicating that this supplement (MB+CSC) influenced feed utilization more positively. From the results of this trial, it may be concluded that straw treatment and/or supplementation can enhance crop residue utilization by sheep. however, mixed supplements especially MB+CSC were more efficient in enhancing the utilization of the straw and consequently animal performance.

Background and Aim: The rearing of quails can have a stronger attraction for the breeders if we lower the cost prices by introducing by-products in their feed formulas. The aim of this study was to evaluate the effects of the partial substitution of soybean meal by apricot kernel cake (AKC) in the diet of quails, applied either sequentially or during all phases of rearing, on their growth performances, carcass characteristics, and meat physicochemical composition. Materials and Methods: A total of 600 one-day-old quails (Coturnix coturnix japonica), with equal sex ratio and weighing on average 7±0.2 g, were randomly distributed in one control group and three experimental groups, the latter being designed according to the rate of application of AKC in either sequential or non-sequential mode in different rearing phases. Each group was divided into five replicates of 30 quails, randomly distributed according to either substitution rate of soybean meal by the AKC (0%, 10%, 20%, or 30%) or farming phase. Results: The average daily gain from the 1st to 45th days (average daily gain1–45d) was found to be the highest (4.24 g/d/subject, p=0.021) for the 30% AKC-supplemented feed lot in either starter or finish incorporation (DFTAA), having an optimum final live weight of 193.4 g (p=0.028), a lowest feed conversion ratio of 3.08 (p=0.001), and a daily feed intake of 860 g (p=0.01). Carcass yield was recorded the highest (74.4%, p=0.02) with an optimum meat protein level (30.6%, p=0.024) and the lowest fat content (2.26%, p=0.001) for the same group as well. Conclusion: The partial substitution of soybean meal by AKC in the quails' fattening feeding, during the finishing phase and for all rearing phases, led to a better growth performance, a better carcass yield, and an improved chemical composition of meat.

<p>The purpose of the present study was to evaluate the effects of including white lupin bran (WLB) in a fattening rabbit diet on growth, carcass traits and nutrient digestibility. The C diet (control) based on alfalfa meal, whereas the WLB 5 and WLB 15 diets were based on white lupin bran (crude protein 152 g/kg, neutral detergent fibre 524 g/kg as-fed basis). The WLB 5 diet contained 50 g of white lupin bran/kg instead of 50 g of alfalfa meal/kg, whereas the WLB 15 diet contained 150 g of white lupin bran/kg, 5 g of soybean meal/kg and 10 g of sugar beet pulp/kg instead of 165 g of alfalfa meal/kg. The diets had similar digestible protein/digestible energy ratios. A total of 150 Hyplus rabbits between the ages of 30 to 73 d were randomly allocated into one of 3 groups and fed one of the 3 experimental diets. Additionally, another 30 Hyplus rabbits (10 per dietary treatment) at the age of 30 d were selected to determine coefficients of total tract apparent digestibility (CTTAD) of diets between 63 and 67 d of age. The dietary treatments did not affect the final live weight of rabbits (mean=2969 g). There was a higher feed intake (+30 g/d; P&lt;0.001) in both groups of rabbits fed the WLB 5 and WLB 15 diets compared to rabbits fed the C diet, which led to impaired feed conversion ratios (P&lt;0.001). Sanitary risk index was not affected by dietary treatment. The rabbits fed the WLB 15 diet exhibited a higher drip loss percentage (+0.65%; P&lt;0.001) than the rabbits fed the other diets, as well as a lower dressing-out percentage (by 1.6%; P=0.024). The CTTAD of the lignocellulose fraction (acid detergent fibre) was significantly higher in rabbits fed the WLB 5 and WLB 15 diets than in those fed the C diet. White lupin bran may be used as a dietary fibrous by-product without significant impairment of the nutritive value of the diet. This lupin by-product can be included in diets for fattening rabbits up to 15% as a partial replacement of alfalfa meal.</p>
