ThesisItem Restricted PERFORMANCE OF SALEM BLACK GOATS SUPPLEMENTED WITH CONCENTRATE FEED DURING DIFFERENT PHYSIOLOGICAL STATES(TANUVAS, CHENNAI, 2021) BHARATHY, N.; TANUVAS; ANANDHA PRAKASH SINGH, D.; SIVAKUMAR, K.; NATARAJAN, A.; MURALI, N.; VASANTHAKUMAR, P.A study was carried out at Livestock Farm Complex, Veterinary College and Research Institute, Namakkal, Tamil Nadu from February 2019 to February 2020 to find out the performance of Salem Black goats supplemented with concentrate feed at graded levels during different physiological states. Two biological trials were conducted to assess the reproductive, growth performance and cost effectiveness of Salem Black goats reared under semi-intensive system of rearing. The first trial was conducted to study the reproductive performance of Salem Black goats using 32 adult female animals (2 to 5 years of age). The experimental groups included control (T1) group allowed for grazing alone, whereas those goats reared under T2 T3 and T4 groups were offered concentrate feed at graded levels viz. 100 g, 200 g and 300 g, respectively during crucial stages of reproduction such as flushing period (3 weeks before and 3 weeks after mating) as well as steaming-up period (4 weeks before and 4 weeks after kidding).ThesisItem Restricted SPORE PROBIOTICS IN PRE-PELLET AND NON-SPORE PROBIOTICS IN POST PELLET ON THE PERFORMANCE OF BROILER CHICKEN(TANUVAS, CHENNAI, 2021) MUTHUSAMY N.; TANUVAS; NATARAJAN, A.; VASANTHAKUMAR, P.; RAJA, A.; KUMARESAN, G.A comparative study was undertaken to evaluate the effect of supplementing spore probiotics in pre-pellet or non-spore conventional probiotics in post-pellet feed on the performance of broiler chicken to assess whether non-spore probiotics adequately perform. Four spore forming B. subtilis (BS, NCDC 70), B. amyloliquefaciens (BA, ATCC 23842), B. coagulans (BC, ATCC 7050), and B. clausii (BCL, BCL 2B) and two non spore forming L. acidophilus (LA, NCDC 15) and B. bifidum (BB, HI 48) probiotics were procured and experimented. BC showed highest recovery (38 %) followed by BS (36 %), BC (33 %), BA (31 %), LA (30 %) and BB (29 %) after spray-drying. Addition in crumble feed and stored for 0, 7 and 14 days at room temperature, BA (8.88 to 8.49 log10 cfu/ml, 4.39 %) and BB (6.03 to 5.14 log10 cfu/ml, 14.76 %) survived better on day 14.
