Effect of Nano Minerals Supplementation on Growth Performance, Blood Biochemical and Carcass Attributes in Chabro Birds

Abstract

The present study was conducted to investigate the effect of nano minerals supplementation on growth performance, blood biochemical and carcass attributes in Chabro birds. 120-day-old Chabro chicks were purchased from CPDO Chandigarh. 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. G2 group was given basal diet along with supplementation of inorganic Zn @ 80 ppm of basal diet. G3, and G4 groups of birds were fed with the basal diet with supplementation of zinc nano particles @ 80 ppm and @100 ppm of basal diet. The mean BW on different weeks of the study period was improved in groups supplemented with inorganic zinc and nano zinc. The highest avg. body weight was seen in the G4 group supplemented with nano zinc (@ 100 ppm) and it was significant (P<0.05). The mean value of BWG differed statistically among the groups and was reported statistically (P<0.05) higher in the G4 group receiving @ 100 ppm nano zinc as compared to all other groups. However, on week 8th 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 nano zinc. 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 control. After 8 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, cholesterol, ALP, SGOT and SGPT 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 G3 and G4 groups, receiving @ 80 ppm and 100 ppm of nano zinc as compared to the G1 and G2 groups. However, the average value of uric acid was statistically higher in the G4 group as compared to the G1 group and statistically similar in G2 and G3 groups. Cholesterol and SGPT are statistically greater in the G4 group as compared to the G1 group and statistically similar in G2 and G3 groups. The average value of SGOT statistically differences was observed among different groups. It was concluded that supplementing inorganic zinc and zinc nanoparticles to the 80 ppm nano zinc improved growth performance, feed utilizaand on in Chabro birds. Without effect of blood biochemical
