Thirty-two (32) TN70 (Topigs Norsvin) weaned pigs, aged 7 weeks, having an average weight of 10.5±0.5 kg were used to evaluate the effect of corn and cob meal (CCM) on the carcass parameters, organ weight, villi morphometric, and organoleptic properties of the pigs. CCM was produced by grinding the grain and the cob together. The pigs were acclimatized for seven days before they were randomly allotted to four (4) dietary treatments with eight (8) pigs per replicate in a completely randomized design. The experiment lasted for seven weeks. The feed had 0%, 10%, 20%, and 30% corn and cob meal (CCM) in the diets tagged as D1, D2, D3, and D4 respectively. All the data were analyzed using SPSS version 16 and the means were compared using one-way analysis of variance (ANOVA). Except for the eviscerated weight, back fat, and loin, all the carcass parameters were significantly influenced (P<0.05). The weight of the visceral organs was significantly influenced (P<0.05) except for the weight of the lungs. All the villi morphometric parameters differed significantly (P<0.05) except the crypt width. CCM influenced (P<0.05) the colour, tenderness, juiciness, and overall acceptability of the meat. The use of 30% CCM stimulated pancreas hypertrophy, increased carcass weight, belly, ham, picnic shoulder, villi height, muscle thickness, and improved organoleptic properties.

The global increase in the production and processing of cassava tubers generates a lot of peel as waste. However, the effect of processing methods to increase the quality of the peel as an animal feed resource must look at the quality of the resultant food products. These effects are insufficiently studied. The study aimed to assess the impact of the processed peel on carcass quality, meat quality, organ weight and organ histology of growing pigs. Thirty (30) male growing pigs (Landrace × Large white) were randomly distributed to five groups with six (6) animals per group in a completely randomized design. Maize was substituted with high quality cassava peel meal (HQCPM) at 0%, 25%, 50%, 75%, and 100% for the experimental diets ranging from diets V to Z. The pigs fed HQCPM diets had higher carcass weights, resulting in an improved carcass yield. The colour, flavour, tenderness, juiciness, texture, and overall acceptability were statistically superior in the pigs fed diet Z. High feed fibre influenced organ weights: the HQCPM diets reduced (P<0.05) the organ weights. More so, the HQCPM diets affected (P<0.05) the histology of the liver and intestine with varying degrees of inflammation, shortened villi length, and reduced surface area. HQCPM diets enhanced the carcass weight and meat quality of growing pigs up to 100% replacement for maize. Nevertheless, the diets reduced organ weights and villi lengths, leading to reduced absorptive function. [ABSTRACT FROM AUTHOR]

Three hundred (300) 21d old (Arbor-acre) broiler chicks apportioned to five (5) dietary groups of sixty (60) birds each, further replicated six (6) times were fed graded levels of toasted pigeon pea seed meal (TPSM) to assess the performance, flock uniformity, organ weights, carcass yield and hepatic histology at the finisher phase. A maize-full-fat soybean meal diet served as the control diet (I). The TPSM was incorporated to replace full-fat soybean meal at 12.5%, 25.0%, 37.5% and 50.0% in diets II, III, IV and V, respectively. Toasting improved the protein content, ether extract, fibre content, metabolizable energy and reduced the anti-nutrients except for oxalate. The final weight, total weight change, average weight gain, feed conversion ratio, eviscerated weight, breast yield and thigh yield were significantly influenced (P0.05). The kidney and abdominal fat were also influenced (P

Three hundred 21-day-old broiler chicks were reared using a 3 x 3 factorial model in a completely randomized design with 10 treatment groups having 3 replicates of 10 birds each. The birds were raised on a commercial starter diet at the starter phase before being allotted into dietary groups in a 21-d feeding trial at the finisher phase. The interaction between treatment and varying inclusion levels of processed-fermented Jatropha curcas (L) kernel meals (JKM) on the performance of broiler chicks was investigated. Jatropha curcas kernels were subjected to three different processing methods, namely: raw defatted fermented meal (RDFM), cooked defatted fermented meal (CDFM) and lye treated defatted fermented meal (LDFM). Each meal was included at varying inclusion levels of 2.5%, 5.0% and 7.5% such that diet 1 (control) contained 0% JKM while diets 2, 3, 4 contained 2.5%, 5.0% and 7.5% RDFM, diets 5, 6, and 7 contained 2.5%, 5.0% and 7.5% CDFM and diets 8, 9, 10 contained 2.5%, 5.0% and 7.5% LDFM. Feeding differently processed-fermented JKM to these broilers did not (p>0.05) compromise the feed conversion ratio. The results indicated an improvement (p

Two hundred (200) 1-d old (Hubbard strain) broiler chicks were used to evaluate the effect of condensed tannin in different sorghum (Sorghum bicolor) varieties on the growth performance and nutrient digestibility of broiler chickens. The birds were randomly assigned to five (5) experimental diets of four (4) replicates each at ten (10) birds per replicate in a completely randomized design in a forty-two day feeding trial. Diet D1 contained 100% maize; D2 and D3 contained 50% and 100% red sorghum variety (RSV) while D4 and D5 contained 50% and 100% white sorghum variety (WSV) respectively as replacement for maize. The RSV had higher tannin content than WSV. Birds fed WSV based diets had higher (P≤0.05) weight gain with better feed conversion ratio than those fed RSV based diets. The sorghum based diets had a more digestible ether extract and nitrogen free extract (P≤0.05) than those fed D1. Conclusively, WSV could completely replace maize because of the lower (condensed) tannin levels while above 50% RSV replacement for maize may be deleterious. [ABSTRACT FROM AUTHOR]
