Abstract
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.
