Influence of Energy and Protein Supplementation on Growth Rate, Empty Body Composition and Ruminal and Blood Metabolites of Goat Kids Fed Hay Diets

Influence of Energy and Protein Supplementation on Growth Rate, Empty Body Composition and Ruminal and Blood Metabolites of Goat Kids Fed Hay Diets

A comparative slaughter experiment was conducted with 28 Spanish kids (BW = 20.6 kg) fed a hay-based diet to determine the effects of supplemental energy and protein on growth rate, body composition, and ruminal and blood metabolites. After 84 d, kids were harvested, digesta contents removed and emp...

Zusammenfassung:A comparative slaughter experiment was conducted with 28 Spanish kids (BW = 20.6 kg) fed a hay-based diet to determine the effects of supplemental energy and protein on growth rate, body composition, and ruminal and blood metabolites. After 84 d, kids were harvested, digesta contents removed and empty body weighed and ground. Samples were freeze-dried and analyzed for DM, CP, ether extract, ash, and gross energy. All kids had increased BW gains. However, unsupplemented kids lost empty BW and weight of all body components except ash. Kids supplemented with energy or protein increased (P
