Abstract This study evaluated effects of unpeeled sweet potato meal (USPM) on performance of finisher broiler chickens. A total of 180 one day-old broiler chicks were used for the experiment. Brooding operation was carried out for 2 weeks. Thereafter, the broiler chickens were managed for additional 2 weeks with provision of starter diet and water ad-libitum. At four weeks old, they were equalized for weight and distributed into three dietary treatments (control, 10% and 15% unpeeled sweet potato meal as partial replacement for maize) each replicated four times with 15 birds per replicate; laid out in a completely randomized design. The birds were managed intensively throughout the experimental period until they attained 7 weeks of age. Data collected were subjected to one-way analysis of variance. Results revealed that the inclusion of unpeeled sweet potato meal up to 15% in diets of finisher broiler chickens did not significantly affect the growth performance indices, haematological parameters, carcass traits and most of the serum metabolites except albumin which showed significant variation and ranged from 1.35 g/dl (15% USPM) to 1.90 g/dl (control). Least significant cost (N129.73) per kg feed was recorded in birds fed diet containing 15% USPM relative to highest cost (N136. 63) per kg feed observed in birds fed control diet. Conclusively, incorporation of unpeeled sweet potato meal up to 15% in diet of finisher broiler chickens reduced cost per kg of broiler finisher diet and had no detrimental implications on growth performance, haematological parameters, serum metabolites and carcass traits in chickens.

The performance of Ross broiler chickens fed on Sweet Potato Meal (SPM) as a dietary source of energy was studied. The study was carried out at both starter (0-4 wks) and finisher (5- 9 wks) phases. In both phases, SPM was incorporated at graded levels of 0. 10, 20, 30, 40 and 50 percent and dietary proteins were adjusted to make the diets iso-nitrogenous. In the starter phase, three replicates of I5 birds each were randomly allocated to each of the 6 treatments in a completely randomized design (CRD) experiment while the number of birds per replicate was reduced to 14 for the finisher phase using the same experimental design. Parameters measured or calculated include feed intake, body weight gain, feed efficiency, feed costs, feed cost/kg weight gain, mortality and carcass characteristics. The results showed similar trends in both phases. Differences in the feed intake were not significant (P>0.05) while weight gain, feed cost/kg weight gain and total cost of rearing the birds decreased significantly (P<0.05). The Control, 10% 20% and 30% SPM diets gave similar weight gain and feed gain ratio. The Control gave the best performance in both starter and finisher phases, although its performance was not significantly different (P>0.05) from that of the 30%SPM diet Sweet Potato Meal level had no adverse effects on mortality and carcass characteristics. It is therefore concluded from this study that SPM should not be included beyond 30% level in a maize-based diet when protein requirement of birds is satisfied.

SUMMARY This work evaluated the effect of including sweet potato meal (SPM), as an alternative to corn in broiler chicken diets, on performance, carcass yield, intestinal morphometry, organ biometry, meat quality and drumstick pigmentation. The study used 936 male Cobb-500 chicks. The experiment had a completely randomized, 3x2 factorial design, with three diet types. These included corn as the energetic ingredient in the standard diet (corn-soybean meal, CSM), and an increasing (ISP) and decreasing (DSP) inclusion of sweet potato meal as a corn substitute, in association with exogenous enzymes, for a total of six treatments with six repetitions and 26 birds per plot. During the period of 1 to 21 days, there was an interaction (P<0.05) for the weight gain (WG) variable; the CSM diets promoted greater WG in relation to the ISP and DSP groups, when supplemented with exogenous enzymes. There was an increase (P<0.05) in surface absorption of the jejunum villi and relative weight of the pancreas, and worse feed conversion (FC), for the ISP and DSP diets. With exception of the pancreas, for the entire period of 1 to 39 days the performance, yield of the carcass and cuts, meat quality, relative weight of the liver, and feet pigmentation variables were not affected (P>0.05) by the factors evaluated. Sweet potato meal, independent of the inclusion program (ISP/DSP) and enzyme supplementation, could partially substitute corn in broiler chicken feed, guaranteeing good performance, carcass yield and meat quality.

The study was carried out to determine the feed value of replacing maize with graded levels of sweet potato vine – cassava composite meal (SPV-CCM) to rabbits. Five treatment diets were formulated to contain SPV-CCM inclusion levels of 0% (control), 25%, 50%, 75% and 100%. Thirty weaned rabbits of mixed breeds and sexes were used for the experiment. They were randomly allocated to five dietary treatments with one rabbit as a replicate in a completely randomized design. Feed and water were provided ad libitum. Parameters measured were that of growth, digestibility, carcass and economics of production. The result showed that there was no significant (P>0.05) difference effect on final weight, total weight gain, daily weight gain and feed conversion ratio across the dietary treatments. There was no significant (P>0.05) difference on crude protein digestibility, crude fibre and ether extract which were within the required values for rabbit. There was no significant (P>0.05) difference on live weight at slaughter, dressing percentage, heart, liver, kidney, lungs/trachea, esophagus, stomach, small intestine, caecum, large intestine and visceral fat, there was however, a significant (P<0.05) difference in dressed weight, pancreases, spleen and kidney fat. A high cost of feeding, cost per kilogram diet and production was recorded in T and low cost of feeding, cost per kilogram diet and production in T . The result showed that 1 5 maize could be replaced by SPV-CCM up to 100% without any adverse effect on their performance, nutrient digestibility and carcass characteristics. However, the optimum performance was observed when 75% SPV-CCM replaced maize in the diet. Replacement of maize with SPV-CCM has relative cost advantage over the control diet and so should be incorporated in the diet of rabbit up to the level considered in this study.
