Bioavailability of zinc in ground beef.
TLDR
The results suggest that the relative bioavailability of Zn in cooked ground beef is as great as that in ZnSO4, whether consumed in diets with or in those without phytate. Expand
Effects of High-tannin Sorghum and Bentonite on the Performance of Laying Hens
TLDR
It was concluded that HTS can be used in layer diets without adverse effects on performance and the use of bentonite to deactivate sorghum tannins is not considered necessary. Expand
Erythrocyte alloantigen diversity and some immunological effects of the B system in related New Hampshire strains.
TLDR
Peripheral blood leukocytes from groups of adults and 5-wk old chickens responded consistently to phytohemagglutinin-M according to their B genotypes, in the order B1B1, B5B5, B6B6. Expand
Iron deficiency reduces the efficacy of tryptophan as a niacin precursor.
TLDR
The results suggest that pellagra in populations having endemic anemia and protein-energy malnutrition may be due not only to inadequate intakes of bioavailable niacin but also to inadequate intake of bio available iron. Expand
Quantitative efficacy of niacin sources for chicks: nicotinic acid, nicotinamide, NAD and tryptophan.
TLDR
Weight gain in the linear response surface of the growth curve proved to be a far better measure of niacin bioactivity than tissue accumulation of NAD(P) in chicks fed the corn-casein diet. Expand
Menadione nicotinamide bisulfite is a bioactive source of vitamin K and niacin activity for chicks.
TLDR
Analysis of weight gain and slope-ratio calculations indicated that both sources of menadione were of equal potency, and no significant differences in slope between the two sources of nicotinamide were revealed. Expand
Genetic parameters for large white pigs reared under intensive management systems in Kenya
TLDR
Growth was highly heritable at pre-weaning and influenced by maternal and common environmental effects and the prospect for selection for high sale weights based on pre- weaning growth performance is evident based on the high genetic correlations among body weight measurements. Expand
Evaluation of Three Management Systems on Growth Performance of Kuchi Indigenous Chicken Ecotype of Kenya
TLDR
It is concluded that Kuchi IC ecotype can equally grow with or without confined management practice, and an ESS management is therefore recommended for KuchiIC ecotype. Expand
Characteristics and Growth Performance of Kuchi Indigenous Chicken
RECOMMENDATIONS To Poultry Breeders: To avoid genetic dilution and erosion of local chicken genetic resource, it is recommended that further characterization of the Kuchi ecotype is made(phenotypicExpand
