Blood metabolic profile of lambs fed complete diet supplemented with exogenous fibrolytic enzymes cocktail

Abstract

Blood metabolic profile (BMP) serve as clinical indicators for the impact of dietary manipulations on physiological health status. The present study was undertaken with the aim to assess the effect of in-feed supplementation of exogenous fibrolytic enzymes (EFE) cocktail as feed additive on BMP in lambs. Crossbred lambs (n=12) of 4-6 months age were distributed into two groups of 6 animals each and fed for a period of 90 days followed by 6 days metabolism trial. Animals in both the groups were offered complete feeds either supplemented with EFE cocktail @ 0.6% DM (Enz) or without any supplementation as control (Con). Haemato-biochemical parameters of animals in both the groups at start (0d) and subsequently at monthly intervals (30, 60 and 90d) were investigated. The EFE supplementation had positive significant (p<0.05) effect on dietary digestible energy content as well as total digestible nutrient intake (g/d) compared to control. However, there were non-significant (p>0.05) effects of EFE supplementation on overall means of all blood cell indices except mean platelet volume (p<0.05) and platelet percent (p<0.01), energy metabolic profile, serum lipid profiles except low-density lipoprotein cholesterol (p<0.05) and atherogenic index (p<0.01), and hepato-renal functioning test profiles. The BMP of EFE supplemented lambs revealed better physiological health status compared to un-supplemented animals. It is concluded that inclusion of EFE cocktail in complete diets for lambs have no adverse effects on the haemato-biochemical parameter suggesting in-feed supplementation of the EFE to improve animals’s health conditions for successfully raising lambs intensively.
