Comparative Efficiency of Nano Mineral on Growth Performance, Blood Biochemical and Carcass Characteristics in Commercial Broiler Production

Abstract

Present study was conducted to investigate the comparative efficiency of nano mineral on growth performance, blood bio chemical and carcass characteristics in commercial broiler production. 200 day-old Cobb 400 chicks were purchased from Venky’s India Limited. Chicks were divided into 5 treatment groups comprising of 4 replicates containing ten birds in each replicate. T1 group of bird was fed with basal or control diet. T2 group was given basal diet along with supplementation of inorganic Zn @ 80 ppm of basal diet. T3, T4 and T5 groups of birds were fed with basal diet with supplementation of zinc nano particles @ 60 ppm, @ 80 ppm and @100 ppm of basal diet. It was observed that zinc supplementation improved the average body weight of birds in all the treated groups. T4 and T5 groups of birds (nano zinc supplemented @80 and 100 ppm, respectively) showed the highest body weight almost in all the weeks. Body weight gain was found higher in nano Zn supplemented groups than both control and inorganic Zn supplemented group. Highest feed consumption was found in control group at 6th week. FCR in nano Zn supplemented groups were significantly lower than control up to 5th weeks of age. Thus feed efficiency was improved by supplementing nano Zn. FCR was found economical up to 4th week of age. After that, feed utilization was not economical for all the groups. In both starter and finisher phase, mineral supplemented groups showed better feed efficiency than control. On the last week of feeding trail blood samples were collected randomly from one bird from each replicate. Blood biochemical parameters like total serum protein, uric acid, cholesterol, ALP, SGOT and SGPT was estimated in collected blood serum. All the blood biochemical parameters were found to be within normal range. After 6 weeks of age, 4 representative birds from each treatment group were randomly selected and slaughtered to study carcass characteristics traits. Dressing %, eviscerated weight % and ready to cook yield % were found to be (P>0.05) similar in all the treatment groups. Thigh, back, neck and wing % varied significantly (P<0.05) among different treatment groups. Though heart and liver % varied significantly among treatment groups, gizzard% remained similar. Periventricular wt. (%) varied significantly among treatments. Though small intestine wt. (%) varied significantly among treatments, small intestine length did not change significantly. Thus, most of the carcass quality traits remained similar after inorganic and nano zinc supplementation. It was concluded that supplementations of zinc nano particles up to the level of 100 ppm of feed improved the growth performance and feed utilization in commercial broiler without affecting blood biochemical and carcass quality traits.
