“…Contrary to this, Patel, [72] reported that addition of EFE @ 0.025% along with the TMR had no effect on average final body weight in Patanwadi sheep. Similarly, supplementation of EFE (Fibrozyme) @ 0, 5 and 10 g per kg of forage had no effect on ADG and FCR in lambs [76].…”

“…Similarly, significantly higherDM intake on the basis of metabolic body weight was observed due to supplementation of EFEto Patanwadi sheep @ 0.025% of TMR [72]. However, there was non-significant difference in the final bodyweightof both the groups (P>0.05).Similarly, addition of EFE (6.23unit protease and 78 unit cellulose/g) to the wheat straw based ration of Barkey lambsshowed higher intake of DM (0.908 Vs. 0.860 kg/d), TDN (0.788 Vs. 0.708 kg/d), CP (155.6Vs.…”

“…They observed non-significant reduction in ruminal ammonia level due to enzyme supplementation indicating slight higher synthesis of microbial protein due to increased uptake of ammonia-N by ruminal microbes. Contrarily, Patel [72] observed that supplementation of EFE to Patanwadi sheep @ 0.025%of TMRshowed non-significant difference (P>0.05) in rumen pH, TVFA level, ammonia-N and NPN levels. Furthermore, total N and protein N increased significantly in enzyme supplemented group compared to control.…”

Dairy production system in developing countries mainly depends on forage plants and crop residues as major portion of the Ruminants diet. The majority of the dry matter in forage crops is made up of fibre whose digestibility is limited in rumen ecosystem. Use of exogenous fibrolytic enzymes (EFE) is gaining popularity in recent days as they overcome the limitations of other methodologies which are used to improve the digestibility of fibre. Due to microbial enzyme activity, ruminants are able to break down fibrous feedstuff, but structural polysaccharides like cellulose, hemicellulose, and lignin will only be partially broken down. The primary purpose of these enzymes is to provide as many nutrients as possible from the indigestible, potentially digestible, and digestible portions of the cell wall. EFE employed in ruminant diets can be divided into three primary categories based on the specific substrates on which their enzyme activity can take place: fibrolytic, amylolytic, and proteolytic. Enzymes can be applied in liquid or granular form to hay, silage, concentrate, TMR, supplement or premix. Even though positive results were obtained, up to date animal responses to EFE supplements have varied greatly due to enzymatic handling, dosage, diet constituents, time and method of applications. This renders need for further dedicated research efforts for the broad generalization of exogenous enzyme usage in ruminant nutrition. The goal of this study was to give a concise summary of the current state of knowledge about EFE usage in ruminant diets and to discuss potential future research areas.
