background: obesity and diabetes are the most important problems of public health. evidence from molecular animal research and epidemiologic investigations indicate that calcium intake may have an influence on body composition, weight and insulin resistance. the objective of this study was to determine the effects of calcium supplementation on body composition, weight, insulin resistance and bl...

A total number of 330 native Libyan chicken eggs were collected from smallholders over different areas of south Libya to determine and classify some quantitative and qualitative traits in Libyan native fowls. The quantitative traits studied in the current trial were fertility and hatchability percent, egg weight, eggshell characteristics (weight, thickness, area), chicks weight and body measure...

Reproduction is an economically important complex composite trait in sheep. Genetic improvement of composite traits can occur by selection for individual components traits, some combination of individual component traits, or by direct selection for the composite trait. This review discusses the responses of selecting directly for litter weight weaned compared to selection responses for one of i...

We incorporated 69 microsatellite loci into an existing data set of 132 markers to test for quantitative trait loci (QTLs) affecting spawning date and body weight in a backcross between two outbred strains of rainbow trout (Oncorhynchus mykiss). Twenty-six linkage groups were identified and synteny of duplicated microsatellite markers was used to confirm 13 homeologous chromosome pairs. Gene-ce...

the base of this review is to consider the relevant role that animal factors (potential milk yield, body weight, body condition score, state of lactation, parity and fertility) play on milk performance (considering the energy balance and the rumen function across the full lactation curve of animals) and milk quality (milk protein content, milk fat content, milk lactose content, vitamins, minera...
