Abstract
Effect of dietary incorporation of cashew apple waste on growth and nutrient utilization in malabari kids were studied and nutrient degradability of cashew apple waste was evaluated using in-vitro method. Eighteen, three months old malabari kids were divided in to three groups of six animals under CRD and G-I was fed with control ration (T1 ), G-II was fed with basal diet plus 10 per cent CAW (T2 ), G-III was fed with basal diet plus 20 per cent CAW (T3 ) for 91 days as per requirement of ICAR, 2013. In-vitro dry matter (IVDMD) and in vitro organic matter degradability (IVOMD) of experimental ration and cashew apple waste were studied using rumen simulation technique (RUSITEC). Incorporation of cashew apple waste in kid starter had significant effect on dry matter intake. The growth performance (average daily weight gain and total weight gain) were better in group fed with kid starter containing 20 per cent CAW in experimental ration (T3) compared to other groups. The digestibility of DM, OM and CP were significantly (P<0.05) lower in experimental ration fed to G III which contains 20 per cent CAW compared to control and no significant difference with GII. There was no significant (P>0.05) difference were observed in digestibility of NDF, ADF, hemicellulose and cellulose among groups. Total digestible nutrient content was higher in experimental ration with 10 per cent CAW than other experimental ration. Total digestible nutrient content of cashew apple waste observed as 58.69 ± 2.80 per cent. In vitro dry matter degradability (IVDMD) was higher in ration with 0 per cent cashew apple waste. In vitro organic matter degradability (IVOMD) was higher in ration containing 10 per cent cashew apple waste. Total in vitro dry matter degradability and in vitro organic matter degradability of cashew apple waste was 42.24 and 86.58 per cent respectively. The cost per kg live weight gain was highest for G I group followed by G II and it was lowest for G III. It was concluded that cashew apple waste can be included in kid starter up to 20 per cent level without any adverse effect on growth performance.
