Comparative Study of Local and Imported Enzymes in Improving the Nutritional Values of Agricultural Waste on Performance and Economic Efficiency of Iraqi Lambs

Abstract

In the current study, we use 25 local Iraqi lambs. With initial body weight (24) kg. The lambs were randomly divided into five treated groups, the first group without treatment as control, the second and third treated with 20%and 40% Agricultural Waste treated with trade enzymes, fourth and fifth treatment 20%and 40% Agricultural Waste treated with local enzymes. The result demonstrated a significant (P<0.01) increase in the quantity of roughages, total feed intake, Neutral Detergent Fiber (NDF) and Acid Detergent Fiber( ADF) and Lignin (ADL) in T5 followed by T4 compared with others treated groups and showed a significant (P<0.01) increase in the digestibility of NDF ,ADF in T4, T5 compare with other treated groups. While T5and T4 recorded Superiority increase in weight gain, and significant improvement in economic cost efficiency with ratio improvement of 5.90, 5.97 % respectively

The Effect of (Laccases, Lignin Peroxidases, Manganese Peroxidases Enzymes) on the Chemical Composition of Rough Fodder

“…The lands allocated for grazing and the cultivated areas as fodder for ruminant animals do not provide their needs. This prompted many researchers to investigate alternatives to increase feed resources and take advantage of agricultural byproduct as much as possible via , improveinge its nutrient value By which animal feed intake increases .and increase the amount of intake of it [1,2,3] by finding alternative methods for chemical treatments to reduce pollution and harmful effects on the revival of the rumen of ruminant animals [4] and that among the advantages of these lowquality feeds is that the concentration of lignin and fiber is relatively high, which limits the extent of their digestion by the rumen organisms in Ruminants due to the presence of a high percentage of lignin in these materials that bind the cellulose molecule and prevent the breakdown of hydrogen bonds [5,6] and that the use of modern biotechnology to improve the nutritional value of feed is one of the main concerns of breeders and researchers and finding alternative methods for chemical treatments to reduce pollution and harmful effects on rumen organisms and the environment [7], enzymes prepared from fungi or bacteria became alternatives to those obtained initially from plants or animals [8]. Biological (enzymes) of some agricultural residues are very necessary for the decomposition of lignocellulose into lignin, cellulose and hemicellulose and improve the content of crude protein, and any improvement in the nutritional value of feed with high fiber content and high digestibility may increase animal productivity [9] external fibrous enzymes work (EFE) can improve the quality of forage before consumption by releasing sugars or by removing structural barriers that restrict microbial access to digestible parts of the feed.…”
