The Effects of Probiotic on Performance, Gut Morphology, Gut Microbial Count and Carcass Characteristics of Partridges

An experiment was conducted under completely randomized design to study the effect of different levels of probiotic (500 and 1000g/feed for 1st phase (25 days) i.e. 35-60 days and at the levels of probiotic (250 and 500g/feed) as 2nd phase (50 days) i.e. 60-110 days. 90 rock partridges (35 day old) were randomly distributed into three treatments and five replicates (6 birds in each replicate) with feed and water ad libitum for 75 days. During experimental period, performance, gut microflora, gut morphology and carcass characteristics of rock partridges were studied. At the end of experiment, two birds were selected from each replicate randomly and slaughtered to study the gut microflora, gut morphology and carcass traits. The experimental diets were as follows: 1= Basal diets (without feed additives), 2= Diet suppl. with probiotic 500g/t feed, 3= Diet included with probiotic 1000g/t feed, 4= Diet contains probiotic 250g/t feed and 5= Diet included with probiotic 500g/t feed. The results indicated that, during 1st phase (25d), the higher and the lower daily feed intake were significantly observed in diets containing probiotic at 1000g/t feed and control groups respectively (p
