    Studies on the nutrient requirements of kids
    (Department of Animal Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 1979) Mercy, A D; KAU; Sivaraman, E
    An investigation was carried out to find out the nutrient requirements for optimum growth in kids. Twenty four Alpine – Malabari crossbred kids of 3 4 months of age formed the experimental subjects for the study. The animals, divided into three identical groups (groups 1, 11 and 111), were maintained on three different levels of nutrient intake for over a total period of 4 ½ months, the parameters recorded during the course of the study being average daily body weight gain, drymatter intake, feed conversion efficiency, digestibility coefficients of nutrients, nitrogen balance, mineral balance and haematological constituents. The average daily gain and feed conversion efficiency recorded for animals in the three groups 1, 11 and 111 were found to be 63.7 + 5.3, 64.4 + 5.0 and 67.6 + 2.0 g and 7.0 + 0.7, 7.5 + 0.5 and 7.9 + 0.3 respectively. The average drymatter consumption of animals were 3.1 + 0.2, 3.5 + 0.3 and 3.6 + 0.3 kg per 100 kg body weight respectively for the three groups 1, 11 and 111. The data collected for the haematological constituents were found to lies within the normal range for the species indicating that all the animals under the three dietary regimes were maintaining normal and sound nutritional status. The requirements arrived at for protein and energy for unit gain in body weight were 0.86 + 0.06 0.90 + 0.06 and 0.89 + 0.03 kg D. C. P. and 4.84 + 0.4, 5.20 + 0.30 and 5.31 + 0.19 kg T. D. N. for the animals in groups 1, 11 and 111 respectively. The requirements of D. C. P., T.D. N., calcium and Phosphorus arrived at from the results obtained during the course of the experiment are considered optimum for normal growth in Alpine – Malabari crossbred kids.

    Evaluation of feeding value of rubber seed cake for promoting growth in calves
    (Department of Nutrition, College of Veterinary and Animal Sciences, Mannuthy, 1977) Viswanathan, T V; KAU; Ananthasubramaniam, C R
    A detailed investigation was carried out to assess the value of rubber seed cake as an ingredient in the concentrate mixture of calves to study the growth rate, nutriture, feed efficiency and economics of rearing. Twenty four, Jersey x Sindhi cross – bred calves of 8 – 14 months of age belonging to the University Livestock Farm, Mannuthy were divided into three equal groups and distributed under three dietary treatments, T1, T2 and T3, the animals being fed concentrate mixtures containing 0, 15 and 30 per cent levels of rubber seed cake respectively for a period of six months. Paddy straw served as the sole roughage. Rubber seed cake at 30 per cent level promoted better weight gains, body size and feed efficiency. Incorporation of rubber seed cake in the concentrate mixture improved the digestibility coefficients of nutrients as also the balance of nitrogen, calcium and phosphorus in the animals. Animals fed rubber seed cake maintained perfect health as evidenced from their haematological values and were free from any toxic effect as adjudged from the histopathological examination of the internal organs and their carcass quality. The cost of feed was found to be 14 per cent lower for kg body weight gain when rubber seed cake was incorporated at 30 per cent level in the concentrate mixture of growing calves. The overall results obtained during the course of the present investigation indicate that rubber seed cake can be incorporated in the concentrate mixture for growing calves at 30 per cent level to achieve both biological and economic efficiency.
