Abstract
Influence of Fibrolytic Enzymes Supplementation on Lactation Performance of Ossimi Ewes
Highlights
The increases in feed prices grains and declines in costs of locally produced enzymes have promoted the interest in the use of enzyme additives in lactating animal diets for increasing the utilization of nutrients and ensuring profitability and sustainability of livestock production activities (Beauchemin et al, 2008)
Biological treatment of agricultural products by fibrolytic enzymes plays an important role in the degradations of cellulose, hemicellulose, and pectin, in turn; simplify those compounds which increase nutrient digestibility in animals supplemented with these enzymes (Aboul-Fotouh et al, 2016)
The chemical composition showed that rice straw (RS) was the highest levels of crude fiber, ash, neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose, and cellulose compared to concentrates feed mixture (CFM) and Egyptian clover (EC)
Summary
The increases in feed prices grains and declines in costs of locally produced enzymes have promoted the interest in the use of enzyme additives in lactating animal diets for increasing the utilization of nutrients and ensuring profitability and sustainability of livestock production activities (Beauchemin et al, 2008). Biological treatment of agricultural products by fibrolytic enzymes plays an important role in the degradations of cellulose, hemicellulose, and pectin, in turn; simplify those compounds which increase nutrient digestibility in animals supplemented with these enzymes (Aboul-Fotouh et al, 2016). The current study aims to determine the influence of supplemented fibrolytic enzymes in lactating ewe’s diet on digestibility of nutrients, milk yield, and composition, FCM yield, feed conversion, and some blood metabolites. An economic evaluation of the tested diets was carried out
