An experiment was conducted to compare wet mash and conventional dry mash feeding for finisher broilers. Feed intake, live-weight gain, feed efficiency and weights of heart, crop, and abdominal fat deposit were significantly (P<0.05) higher in broilers receiving the wet mash. Water intake and gizzard weight were significantly (P<0.05) higher in birds fed dry mash. No significant (P<0.05) differences were observed in dressing percentage, weights of liver, intestine and the proventriculus. The results of this experiment demonstrated that wet feeding is not deleterious to the performance of broilers in the tropics. It also concluded that wet feeding is desirable not under hot weather conditions alone, but also during the rainy season.

An experiment was conducted, with objective to determine the feed consumption, final live weight, weight gain, feed efficiency and economy in broiler chicken fed with locally available low protein based diets (20 percent CP in starter and 18 percent CP in finisher) supplemented with methionine, lysine and homeopathic medicine alfalfa. For this hundred fifty day-old birds of commercial broiler (Vencobb) were randomly assigned to five dietary treatments(10 chicks/treatment) and replicated three times in CRD with treatments composition of low protein based diets (LPB)  (T0), LPB+ 100g/100 met + 300g/100  lysine (T1), LPB + 200g/100 met +300g/100lysine (T2), LPB + Alfalfa 5ml/100 chicks 2 day in week with drinking water (T3) and LPB + Alfalfa 5ml/100 chicks 3 day in week with drinking water (T4). Synthetic methionine and lysine was used for supplementation of deficient amino acid. Same condition was applied in finisher diets of broiler chicken. The result showed that chicks fed with LPB in both starter and finisher diet had significantly (P<0.05) lower feed intake, final live weight , total weight gain, feed efficiency and income over feed and chicks cost (IOFCC) with compromising chicks fed with LPB with addition of methionine and lysine each and also homeopathic medicine alfalfa in starter and finisher period. Highest feed intake, final live weight, weight gain, feed efficiency was obtained with treatment (T1) followed by treatment (T2). However, positive growth response and better health status of chicks was also observed from supplementation of homeopathic medicine alfalfa with LPB and non-significant difference on Income Over Feed and Chicks Cost was obtained with treatment (T1). So, it was concluded that with supplemental methionine, lysine and alfalfa, the CP level of broiler chicks could be reduced up to 20 percent in starter and 18 percent in finisher diets without adverse effect on feed intake, final live weight, weight gain, feed efficiency and Income overfeed and chicks cost, provided under locally based feed ingredients.Int.

Performance and other parameters of broiler chickens could be influenced by the environment (feeds, housing, climate) and genetic potentials (breeds). Three hundred (300) broiler chicks comprising of one hundred each of the three breeds designated as A, B and C were used in a completely randomized design experiment which lasted for 56 days. Each breed represents a treatment with 5 replicates of 20 birds each. The birds were fed ad libitum with the same commercial starter and finisher diets throughout the period of the study; and water supplied free of choice. Average final body weight, average daily feed intake, average daily weight gain, feed conversion ratio, cost/kg feed and cost of feed/kg live weight gains at the starter and finisher phase were the performance parameters measured. Carcass, serum and haematological indices of these birds were also investigated. Proximate composition of the experimental starter and finisher diets indicated that both were adequately formulated for birds in the tropics under which the study was carried out. Results of the performance parameters showed that the values were similar for the starters and finishers except for highest (P<0.05) feed intake of 134.68g/b/d obtained for breed A compared with 112.01g/b/d and 106.69g/b/d respectively for breeds C and B at the finisher phase. The highest (P< 0.05) cost (N 210.94) of feed per kg live weight gain was obtained for breed A than N 196.10 and N 190.80 respectively for breeds B and C at the starter phase. The average cost of feed per kg live weight (1-8 weeks) were N 282.54, N 270.30 and N 269.28 respectively for breeds A, B and C; with breed C having the lowest cost. The dressed weights were 62.86, 67.29 and 67.84% for breeds A, B and C in the same order. The abdominal fat reduced (P < 0.05) from 1.52% in breed A to 1.02% and 0.77% in breeds B and C. Although the thighs were similar across the breeds, variations in the drumstick, 10.27g/kg breed A, 11.69g/kg breed B and 10.64g/kg breed C differed (P< 0.05). The breast increased (P< 0.05) from 18.62g/kg breed A to 20.36g/kg breed B and 21.95g/kg breed C. Globulin and neutrophils were the only blood indices which differed (P < 0.05) across the breeds at the starter phase. Breed C was considered the best of the 3 breeds in terms of performance, cost, carcass and health status indicated by blood indices; and could be recommended for commercial broiler production for better economic returns.

Two experiments were conducted to evaluate the inclusion of biscuit waste in broiler diets. Performance was measured as growth rate and feed efficiency when 10, 25, 50, 75 and 100% of maize in a control diet was replaced by the by-product and fed to broilers for 12 weeks. Substitution for maize at 100% level significantly (P<0.05) affected performance although he cost of feed/kg live weight gain was N1.41 com­pared with ₦1.82 for the control diet. Ikletabolizable energy and nitrogen retention was not affected by dietary treatment but fat retention was significantly higher (P< 0.05) at 75 and 100% substitution. The carcass weights expressed as percentage of liveweights were not significantly affected but abdominal fat deposition was higher of the high levels of inclusion of biscuit waste. When maize was completely eliminated from the diet, bulking with 5, 7.5 or 10% maize cob as additional fibre source increas­ed feed intake but inclusion beyond 5% level did not improve feed efficiency. Fat and nitrogen retention and abdominal fat deposi­ted significantly (P • 0.05) decreased at 7.5 and 10% maize cob inclusion but gizzard weight increased.

To investigate the effects of copper sulfate (CuSO4.5H2O) and zinc sulfate (ZnSO4) on growth performance, feed intake, feed efficiency and carcass characteristics of commercial broiler an experiment was conducted. Total 80 Cobb-500 of 07 days old chicks were randomly divided into four dietary groups having four replications in each. Four diets were considered: control (T0); CuSO4.5H2O @ 150 mg/kg of commercial diet (T1); ZnSO4 @100 mg/kg on diet (T2); and combination of CuSO4.5H2O + ZnSO4 @ 150 mg/kg + 100 mg/kg of diet (T3), respectively. Initial live weight, live weight gain and feed intake were recorded. Carcass characteristics were observed after slaughtering of birds. The final live weight was significantly (P<0.05) differed among the experimental groups where highest live weight was recorded in T2 (2440 g/bird) group. Broilers in T2 group showed the best feed efficiency (1.67) that varied significantly (P<0.05). Daily live weight gain was differed significantly (P<0.05) among the experimental groups where highest value at 3rd and 4th weeks of experiment was found in birds of T2 group. There were no significant (P>0.05) differences observed among the dietary treatment groups in terms of de-feathering percentages, liver, heart and abdominal fat weight. On the contrary, significant (P<0.05) difference were observed in carcass weight, where highest value was recorded in T3 group. Thigh and breast weight was also differed significantly (P<0.05) in T3 group compared to control and other groups. Use of copper sulfate pentahydrate in diet was economic in terms of cost benefit analysis. Res. Agric., Livest. Fish.7(3): 465-474,  December 2020

A six weeks trial was carried out to study the effect of feeding cottonseed meal (CSM) with 432, day - old Cobb 400 broiler chicks distributed to nine experimental diets with six replicates, each containing eight chicks. The experimental diets were formulated based on total amino acids (TAA) or based on digestible amino acids (DAA) with or without iron supplementation with two levels of CSM (2 and 4%) and control diet based on maize – soyabean. Birds fed with CSM at 4% DAA without iron supplementation had higher body weight gain than the control (1918 vs 1804g). Feed intake and feed efficiency were comparable in birds fed with different experimental diets. Inclusion of CSM up to 4% TAA or DAA with or without iron supplementation had comparable dressing percentage, gizzard, giblet (% of live body weight) and spleen (g). The liver weight (% of live weight) was lower in birds fed 4% CSM - TAA and 2 or 4% CSM - DAA with or without iron supplementation (1.45 – 1.53 vs 1.65%). Heart weight was higher (0.91 vs 0.80% of live weight) and abdominal fat (15.42 vs 24.0g) was lowered in 4% CSM - DAA with iron supplementation. The cost of feed/kg live weight gain in the diet of 4% CSM - DAA was lowest (52.77), followed by 4% CSM - TAA (55.43) and the difference with control was Rs 5.43 and Rs 2.77 respectively. The overall performance based on body weight gain, feed intake and feed efficiency was better in the diet formulated with 4% level of CSM - DAA.

SUMMARYIndonesian Ongole and swamp buffalo bulls that had previously been given 0, 1·2, 2·4, 3·6 or 4·8 kg/head/day rice bran plus ad libitum elephant grass were slaughtered after 161 days feeding. Abdominal depot fat, full and empty reticulo-rumen and cold carcass weights were recorded. Various carcass variables were measured and the 9–10–11 rib joints were dissected into bone, muscle and fat. Carcass gross energy was calculated from rib-fat content using previously determined regression equations. Feed efficiency was expressed in terms of the ratios of live-weight gain or carcass-energy accretion to metabolizable energy available for growth.Increasing supplementation with rice bran resulted in larger abdominal fat depots, higher dressing percentages, increased carcass fatness (and hence carcass gross energy) and improved rib muscle to bone ratios. Carcass conformation was unaffected by dietary treatment. When feed efficiency was expressed per unit live-weight gain, there was a decrease with increasing rice-bran feeding. Feed efficiency, expressed per unit of carcass energy accretion, improved with rice-bran supplementation and was generally higher in buffalo than in Ongole bulls. Dietary and species differences in feed efficiency could be primarily explained by the differential energy cost of deposition of, and the availability of energy from, carcass protein and lipid.

Data from Danish Progeny Testing Stations were used to investigate the relationship between the colour of meat and feed efficiency in pigs. For groups slaughtered during the summer there was a highly significant correlation. As the amount of feed consumed per unit live-weight gain declined so the meat became paler. For groups slaughtered in winter and for data pooled over the whole year, there was no significant correlation. Possible explanations of these findings are discussed.

The objective of this work was to evaluate the effects of two types of incubation and two types of feeding on the performance of chickens and intestinal development of chicks during the pre-starter phase (1 to 7 days of age). One-year-old male Ross® chicks were used. The experimental design was a randomized complete block design, in a 2x2 factorial design, with two types of feed processing (bran and micropelleted) and two types of incubation machines (single and multiple stage), totaling four treatments, with four treatment repetitions each. Twelve birds per experimental unit were used, totaling 192 animals. Performance evaluations were conducted, such as mean weight, weight gain, feed intake, feed conversion, bowel weight and size, and percentage of intestine in relation to live weight. Histomorphometric tests on the height of the villi and depth of the duodenal crypts were also performed. The two incubation machines did not influence any of the analyzed variables. Even though both had the same composition, the micropelleted feed resulted in positive gains for the performance variables: average weight, weight gain, feed intake, and feed conversion when compared to the meal, but was unable to significantly influence the morphometric measurements of the duodenum of chicks in the pre-starter phase.
