Abstract

Introduction: The application of enzymes in poultry diets for the enhancement of Nutrient availability and Performance had been reported since 1926. Previously, the research conducted on feed enzymes in poultry nutrition focused on non-starch polysaccharide (NSP) degrading enzymes, especially xylanase and β-glucanase, in diets containing wheat, rye and barley (Choct, 2006). The use of unconventional feedstuff for poultry production is however limited due to their fibrousness and inability of birds to possess the cellulase enzyme that can digest the fibre (Kocher et al., 2001). Exogenous enzymes capable of degrading non-starch polysaccharides (NSP) in broiler diets based on cearls grains, including wheat and barley (Bedford and Schulze, 1998), initiated this practice. Researchers found that the use of NSP-degrading enzymes in barley and wheat based broiler diets improved litter quality and Performance. The use of NSP-degrading enzymes in wheat and barley based diets for broilers are therefore well established and accepted (Bedford, 1998). Advances in the field of nutrition have made it possible for improvement in the utilization of lesserknown feedstuffs. One of these advances is the use of enzyme technology, which can ameliorate the negative effects of dietary nonstarch polysaccharides in high fiber feed stuffs. Kemin (KYM) is a concentrated multi-enzyme (multi-enzyme complexes are stable assemblies of more than one enzyme, generally involved in sequential catalytic transformation) made from the same organism and fermentation process. It was suggested by the manufacturer that the commercial blend could improve energy metabolism up to 6% and enhance protein utilization up to 2%. Cowieson et al. (2006) observed the Nutrient metabolism of broilers fed corn and soybean meal diets was increased by a combination of xylanase, amylase, protease, and phytase so it can be use for efficient digestion of Nutrient. As a result of limited published studies evaluating the effect of multi-enzyme preparation on layer hens, this study was conducted to assess the effects of commercial enzyme on production and egg traits and apparent Nutrient utilization. The effects of Kemzyme© were evaluated on Performance, egg quality and Nutrient Digestibility in Hy line w36 Laying hen at 60 weeks of age. Material and methods: In first experiment was carry outin complete randomized design with 450 layer hen at 60 weeks of age in six tratments as follows; 1-common diet (control), 2-diluent diet 90% of common diet (negative control), 3-diluent diet plus enzyme (0. 25 gkg -1 ), 4-diluent diet plus enzyme (0. 50 gkg -1 ), 5-diluent diet plus enzyme (0. 75 gkg -1 ) 6-diluent diet plus enzyme (1 gkg -1 ) with five replicate (18 hen in each). Productive Performance of hens was recorded for eight weeks and egg quality parameters were measured on the last week of trial. The following data were evaluated: initial body weight, feed intake, and feed to gain. The birds were weighed on the first day of the experiment. Fresh feed was made available daily and the remaining feed was weighed at the end of the week to calculate feed intake and feed to gain. Second experiment, was done with 100 Hy Line W36 layer hen at 70 wks age in same treatment and replicate of experiment one. Four birds from each replicate were selected and placed in clean, disinfected, and steel frame cages equipped with a grid floor and collector tray. Three d of the acclimatization period were allowed prior to the commencement of excreta collection. A known weight (more than enough) of feed was given to each treatment group daily while the total excreta collection was done daily for a period of three. The daily excreta samples for each replicate was weighed, dried and the cumulative samples pooled and used to determine the proximate composition according to AOAC (2000). Diets, excreta samples, were analyzed using the standard methods of the Association of Official Analytical Chemists (AOAC International, 2000). Moisture content as dry matter (DM, AOAC, 2000; 930. 15), crude protein (CP, AOAC, 2000; 990; 03), ether extract (EE, AOAC, 2000; 954. 02), crude fibre (CF, AOAC, 2000; 978. 10), and crude ash (CA, AOAC, 2000; 942. 05) of samples was determined in four replications after samples were ground. Digestibility of gross energy, organic matter, dry matter and ether extract was calculated base on marker method. Result and discussion: Enzyme supplementations have significant effect on feed intake, egg production, egg mass, and FCR in the present study. In negative control group that Including diets with 90 percentage of common diet Nutrient in the present experiment significantly decreased egg weight but supplementation of this diet with 0. 50 gkg -1 enzyme can ameliorate this negative effect. Feed cost, enrgy intake and energy conversion ratio were increased in the hens fed enzyme-included diets compared to hens fed the negative and positive control diet. Protien intake and conversion ratio was improved by enzyme supplementation in diluent diet. Egg quality such as Albumen height, Haugh unit and Egg shell weight were increased in the hens fed enzyme supplemented diets compared to hens fed the negative and positive control diet. There was significant effect of enzyme was detected on Digestibility of Gross energy (GE), dry matter (DM), organic matter (OM), (P<0. 05). Conclusion: Generally, the use of Kemin® especially at 0. 50 gkg-1 in diet improve Performance traits, egg quality and feed intake, Nutrient Digestibility, and energy in the Hy-line w36 Laying hen at late production phase.
