Effect of sex and genotype on protein metabolism parameters in the liver of the young goat

摘要

Feed intake proved lower while feed efficiency higher in Polish White (PW) compared to F1 (Boer x PW) kid goats. Both indicators proved higher in males than in females. These may be explained by possible differences in energy and nitrogen utilization.Because contribution of liver to total energy expenditure and to total protein synthesis in the whole body is important in other animal species, the objective of this study was to relate differences in growth between genotypes and sexes to possible differences in the liver nitrogen metabolism of the goat.
