Aim:The present study was conducted to evaluate the dietary addition of Emblica officinalis (Amla) fruit powder as a growth promoter in commercial broiler chickens.Materials and Methods:An experiment was conducted on 135 commercial broiler chicks (Ven-Cobb 400 strain) divided into three groups with three replicates of 15 chicks each. Three treatment groups were as follows – T1: Basal diet as per BIS standards; T2: Basal diet supplemented with 0.4% of E. officinalis fruit powder; and T3: Basal diet supplemented with 0.8% of E. officinalis fruit powder.Results:The average body weights at the end of the 6th week were significantly higher (p<0.05) in groups T2 and T3 compared to group T1. Feed intake, feed conversion ratio and feed cost per kg live weight production were similar among the treatment groups. The net profit per bird was the highest in group T2 (Rs. 19.22/bird) followed by group T3 (Rs. 17.86/bird) and the lowest in group T1 (Rs. 14.61/bird).Conclusion:Based on the results of the present study, it was concluded that dietary addition of E. officinalis (Amla) fruit powder had a positive effect on growth performance and net profit per bird in commercial broiler chickens.

The present investigation was conducted to compare relative efficiency of four lactation curve models in Gir cattle. This study was carried out on 1246 normal lactation records (1-6 parity) pertaining to 357 Gir cows spread over 15 years (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)

The present study was carried out for six weeks to investigate the effects of adding graded levels (0, 0.1 and 0.5%) of garlic (Allium sativum) powder to the basal experimental diet on the growth performance and carcass characteristics of broiler chicks. One hundred and eighty (n = 180) day old unsexed white commercial broiler chicks (Cobb-400) were randomly distributed into three dietary treatments of 60 birds/treatment and each treatment contained 4 replicates (15 birds/replicate). The dietary treatments were controlled basal diet (T1), and a diet supplemented with garlic powder at 0.1% (T2) and 0.5% (T3). Daily feed intake, weekly body weight, and residue leftover were recorded to calculate the feed conversion ratio (FCR). At the end of the experiment, six birds from each group were sacrificed to determine the carcass characteristics. Results revealed that dietary supplementation of 0.1% garlic powder (T2) significantly (p less than 0.01) improved body weight, body weight gain, feed intake and FCR as compared to birds supplemented with 0.5% garlic powder (T3) and control diet (T1). Dietary supplementation of 0.1% garlic (T2) resulted in significant (p less than 0.05) improvement in dressed yield as comparedto T3 and T1. On the other hand, comparable (p greator than 0.05) effect was observed on shrinkage loss, blood loss, feather loss, eviscerated yieldand relative weight of giblet. Thus, dietary supplementation of 0.1% garlic powder had beneficial effects on growth performance and dressed yield of broiler chicks.
