BookPublisher: 1994Subject(s): Department of Animal NutritionDDC classification: 0409,T Dissertation note: Dried brewer's yeast (DBY) (Saccharomyces cerevisiae) is a byproduct of the brewing industry and is a valuable food for animals. DBY contains 45% CP and 35% soluble carbohydrate. The amino acid profile of DBY is comparable to other vegetable protein supplement (VPS) like SBM. The present study was designed to study the effect of substitution of SBM with DBY on the performance of Japanese quails..
For the purpose quails were fed with five rations in which SBM was replaced with DBY at 0, 25, 50, 75 and 100% levels for 42 days. Weekly weight gain and daily feed consumption was recorded. Maximum weight gain (144.61g), feed efficiency (4.01) carcass weight (104.72g) and dressing percentage (69.53%) was observed in quails fed ration in which 100% SBM was replaced with DBY. Minimum weight gain (137.67 g) poor feed efficiency (4.21) lower carcass weight (78.28g) and poor dressing percentage (54.48%) was recorded in quails fed ration in which 100% DBY was replaced with SBM. No adverse effect on internal organs liver, heart and carcass was seen.
From the foregoing study it was concluded that DBY could be successfully incorporated in quails rations upto 10% without any undesirable effect on the performance of quails. It has been demonstrated from the results that DBY improves body weight gain, feed efficiency and dressing percentage which ultimately decreases the cost of quality meat production. The study also indicated that rations containing DBY were comparatively cheaper and cost per kg of live weight was decreased and net profit per quail was greater.
