Effect of Beta-glucanase and Phytase Supplementation on Growth, Hemato-biochemical and Sensory Attributes in Broiler Chicken

Abstract

The present study entitled “Effect of beta-glucanase and phytase supplementation on growth haemato-biochemical and sensory attributes of broiler chicken” was conducted on 120-day-old broiler chickens, Chicks were divided into 4 treatment groups comprising 3 replicates containing ten birds in each replicate. The G1 group of birds was fed the basal or control diet. The G2 group was given a basal diet along with supplementation of beta-glucanase 600 unit/kg of basal diet. The G3 group was given a basal diet along with supplementation of phytase 600 unit/kg of basal diet and the G4 groups of birds were fed with the basal diet with supplementation of beta-glucanase and phytase 600+600 unit /kg of basal diet. The mean body weight on different weeks of the study period was improved in groups supplemented with beta-glucanase and phytase. The mean value of BWG differed statistically among the groups and was reported statistically (P<0.05) higher in the G3 group phytase as compared to all other groups. However, on week 5 of the study period, average feed consumption was statistically higher (P<0.05) in the control as compared to all treatment groups. Thus feed efficiency was improved by supplementing beta-glucanase and phytase. The FCR on different weeks of the study period did not differ among the groups. Final FCR also followed a similar trend. In both the starter and finisher phases, mineral-supplemented groups showed better feed efficiency than the control. After 5 weeks of age, 6 representative birds from each treatment group were randomly selected and slaughtered to study carcass characteristics traits. Shrinkage (%) (P< 0.05) significantly among different treatment groups. Dressing %, eviscerated weight %, and ready-to-cook yield % were found to be (P>0.05) similar in all the treatment groups. Breast and wing % varied significantly (P<0.05) among different treatment groups. Thigh, back, neck, and heart do not vary significantly (P<0.05) among different treatment groups. Though liver and gizzard % varied significantly among all periventricular wt. percent varied significantly among treatments. Though small intestine weight percent varied significantly among treatments, small intestine length did not change significantly. Large intestine weight percent and large intestine length (cm/gm) were also found no-similar among treatments. Average cecal length (cm/100gm) differs significantly among treatment groups. On the last week of the feeding trial, blood samples were collected randomly from one bird from each replicate. Blood biochemical parameters like total serum protein, uric acid, ALP, SGOT, SPGT, and, cholesterol were estimated in collected blood serum. All the blood biochemical parameters were found to be within the normal range. However, the average value of total serum protein was statistically higher in G2 and G3 groups, receiving However, the average value of uric acid was statistically higher in the G2 group as compared to all groups and statistically similar in G1 and G3 groups. ALP and SGOT are statistically greater in the G3 group as compared to the G1 group and statistically similar in G2 and G3 groups. The average value of SGOT statistical differences was observed among different groups. It was concluded that supplementing beta-glucanase and phytase 600 units each per kg improved growth performance feed utilization in broiler birds without the effect of blood biochemicals.
