A study was conducted in crossbred calves for a period of 90 days to evaluate the effect of soy protein isolate based milk replacer feeding on digestibility of nutrients and haematobiochemical parameters.Twelve,four-day-old crossbred calveswere selected from University Livestock Farm and Fodder Research and Development Scheme (ULF & FRDS), Mannuthy and were allotted to one of the two dietary treatments. The dietary treatments were T1 (Control) fed with whole milk and T2- fed with soy protein isolate based milk replacer (CP-22 per cent) and milk in the ratio 3:1.To all the experimental animals, calf starter (CP-23 per cent) and adlibitum green grass were offered and were fed according to ICAR (2013). Daily record of quantity of feed (calf starter and milk replacer) andgrass given and balance if any were recorded throughout the experimental period. A digestibility trial for five days duration was carried out towards the end of feeding trial by total collection method. The results revealed similar apparent digestibility of nutrients and haematobiochemical parameters for whole milk and milk replacer fed group.

A study was conducted to examine the effect of inclusion of Indukantham kashayam residue on growth performance and economics of production of weaned New Zealand White rabbits. Eighteen weaned New Zealand White rabbits of four to six weeks age were selected from Rabbit Breeding Station, College of Veterinary and Animal Sciences, Mannuthy. The experimental animals were randomly divided into three groups of six animals each and one of the three dietary treatments T1 (control diet with 18 per cent CP and 2700 kcal DE), T2 (Diet containing 5 per cent Indukantham kashayam residues) and T3 (Diet containing 10 per cent Indukantham kashayam residues) was alloted to each group. Data on weekly weight gain and daily feed intake were collected during course of study, while feed conversion ratio and economics of production were computed. The findings of the current study revealed that growth performance of weaned New Zealand White rabbits remained unaffected (p>0.05) among the dietary treatments. Indukantham kashayam residue can be included in the diet of growing rabbits up to 10 per cent level to reduce cost of production.
