Performance of laying pullets fed on cereal-free diets based on maize offal, cassava peel and reject cashew nut meal.

1. A 70-d experiment was conducted to determine the response of 26-week-old laying pullets to cereal-free diets based on maize offal, cassava peel and full-fat cashew nut meal (CNM) in comparison with a standard 550 g maize/kg reference diet. The 4 test diets all contained 315 g CNM/kg 232.

Protein quality of raw and autoclaved cowpeas: comparison between some insect resistant and susceptible varieties.

A comparative study was conducted with four improved cowpea (2 pod bug resistant and 2 susceptible) varieties to assess the effect of autoclaving at 105 degrees C under 15 psi for 30 min on their protein quality, as measured by the levels of some antinutritional factors and performance of rats fed the different cowpea diets. Also, the relationships between antinutrients in the cowpeas and protein quality indicators were examined. Results showed that autoclaving completely eliminated trypsin inhibitor, hemagglutinin and HCN, whereas it reduced significantly (p < 0.

Prevalence of aflatoxin B1 in commercial poultry rations in Nigeria.

122 samples of commercial poultry feed from 5 southern states of the Republic of Nigeria were investigated for their content of aflatoxin B1.57.4% of all samples examined contained aflatoxin B1.

Cyanide, protein and iodine interaction in the performance and metabolism of rats.

Performance and metabolic traits were measured in sixty-four growing rats fed on varying levels of dietary cyanide, protein and iodine. The presence of cyanide in the diets caused a non-significant reduction in both feed consumption and growth rate. Moreover, on protein deficient diets, the lowest body weight gain was obtained in the animals with 750 ppm cyanide.

Protein metabolism in growing pigs fed corn or cassava peel based diets containing graded protein levels.

Sixty-four Large White cross Landrace weanling pigs were randomly allotted to eight treatments in a two by four factorial arrangement. The two dietary variables were cassava peel (0 and 40 per cent) and crude protein (20, 15, 10 and 5 per cent). Total serum protein concentration was significantly (P less than 0.

Serum and tissue thiocyanate concentrations in growing pigs fed cassava peel or corn based diets containing graded protein levels.

Thiocyanate concentrations of serum, liver, kidney, spleen and longissimus dorsi were determined in 64 growing Large White x Landrace pigs offered 8 experimental isocaloric diets containing different levels of cassava peel and crude protein. Cassava peel increased serum thiocyanate on day 60 (P less than 0.01) and day 90 (P less than 0.

Cyanide, protein and iodine interactions in the performance, metabolism and pathology of pigs.

Performance and metabolic and pathological changes were evaluated in 48 growing pigs fed different levels of dietary protein, cyanide and iodine. Protein deficiency reduced urinary iodine excretion and the concentrations in serum of protein, protein bound iodine and thiocyanate. It also reduced liver rhodanese activity and caused a decrease in urinary thiocyanate excretion which was not significant.

Performance of the African giant rat (Cricetomys gambianus Waterhouse) on commercial rations and varying dietary protein levels.

The growth performance of 24 weanling giant rats was studied in 2 experiments of 30 weeks duration with commercial livestock rations and graded levels of protein. Daily average liveweight gain was 5.1-7.
