Aim:The present study was carried out to evaluate the effect of supplementation of garlic, ginger and their combination in the diets of broiler chickens and assessment in terms of feed intake, growth performance and economics of feeding.Materials and Methods:A total of 240 1-day-old Cobb-400 broiler chicks were randomly assigned to four dietary treatments each with three replicates of 20 chicks per replicate (n=60). Four experimental diets were formulated in such a way that control diet (T1) contained neither ginger nor garlic. While, birds in group T2 and T3 were fed with diets containing 1% garlic and ginger, respectively. Diet 4 (T4 group) contained a combination of 1% of garlic and ginger. The feeding experiment was carried out for 42 days, and different parameters evaluated includes feed intake, weight gain, feed conversion ratio, gut morphometry, and economics of feeding in terms of return over feed cost (ROFC) and European Performance Efficiency Index.Results:Feed intake of experimental birds in ginger and mixture of garlic and ginger supplemented groups, i.e., T3 and T4 groups have significantly (p<0.05) higher feed intake as compared to control. While, feeding of garlic have non-significant effect on feed intake as compared to other groups. A body weight gain (g/bird) was found to be significantly (p<0.05) higher in garlic (T2 group) and ginger (T3 group) supplemented group as compare to control and garlic and ginger mixture supplemented group (T4 group). Feed conversion ratio was significantly (p<0.05) lower in ginger (T3 group) supplemented group as compare to other groups. Mean villi length, villi width and cryptal depth were significantly (p<0.05) higher in T3 group than rest of all three groups, indicating increased absorptive surface area. ROFC was significantly (p<0.05) lower in T3 and T4 groups as compare to control. However, it was not significantly different between control and T2 group.Conclusion:On the basis of the results of the study, it is concluded that supplementation of garlic improves the performance of broilers when added at the rate of 1% of broiler ration and can be a viable alternative to antibiotic growth promoter in the feeding of broiler chicken.

Aim: Our objective was to evaluate the effect of bypass nutrients i.e. bypass lysine, methionine and fat on growth and nutritional efficiency in growing Jaffrabadi buffalo heifers aged 21 to 27 months.Materials and Methods: Twenty buffalo heifers were divided into four groups of equal number: control group (T1), bypass fat supplementation (T2), bypass lysine and methionine supplementation (T3) and bypass lysine, methionine and fat supplementation (T4). The feeds were analyzed for proximate constituents. Body measurements (body length, body height, heart girth, body girth, pelvic length and pelvic width) as well as body weights (kg) of individual animals were recorded at the beginning and thereafter at every fifteen day interval throughout the experimental period. Feed conversion ratio was determined in terms of dry matter required per kg gain in body weight under different treatments.Results: The total weight gain and average daily body weight gain during the experiment was highest in T4 followed by T2, which differed significantly (P<0.05) from that of T1. Biometric changes were uniform in all the experimental groups and the changes were positive. Heifers under the present experimental condition, gained biometry considerably though not significantly. Treatment differences were significant (P<0.05) for average value of percent dry matter intake but no significant differences were found between treatments for average daily dry matter intake and dry matter intake per kg metabolic body weight. The efficiency of feed utilization was best in T4 followed by T2, T3 and T1 groups but the treatment differences were statistically non significant (P>0.05). Conclusion:Incorporation of bypass nutrients (lysine, methionine and fat) in the ration of growing Jaffrabadi heifers improved live weight gain, dry matter intake (kg/day), dry matter intake per kg metabolic weight and feed conversion ratio (DMI/kg body weight gain).

The present study was carried out to evaluate the effects of exposure at different doses of acephate on hematology, blood biochemistry, oxidative stress and immune system of Wistar rats. The experiment was carried out on 40 Wistar rats, which were divided in four groups. Animals of the three treatment groups were given with different sublethal doses (1/40th, 1/20th, 1/10th of lethal dose 50 value) of acephate by oral gavage. The hematology, blood biochemistry, oxidative stress marker, humoral immune response and cell-mediated immunity were evaluated following acephate exposure. Significant alteration in hematological parameters was not observed following different doses of acephate; however, significant alteration in alkaline phosphatase, gamma glutamyl transferase, acetyl cholinesterase, lipid peroxidase and superoxide dismutase was observed in medium- and high-dose group animals. Nonsignificant decrease in antibody titer in animals exposed to high dose has been observed compared with animals of control group. However, significant alteration in cell-mediated immunity was not observed in animals treated with acephate at different doses.
