Near-infrared Spectroscopy Method to Evaluate UDP Content of Protein Supplements

Weaned Barbari kids (24; 3–4 m old of 11.7±0.6 kg BW) randomly divided in to three equal groups were offered concentrate mixture containing either 0.29, 0.44 or 0.59% P, supplemented with 330 g pegion pea straw and 300–400 g/d berseem fodder for 120 days. The roughage and concentrate ratio was 60: 40 in all the treatments. The ADG (g) and FCR were 70.0 and 11.0; 77.8 and 12.3; 76.3 and 12.0 respectively in T1, T2 and T3 groups. The animals were in positive nitrogen, calcium and phosphorus balances. Significantly (P<0.05) increase in phosphorus balance was observed. The digestibility of nutrients was not infleunced by level of P. It was conclude that increased phosphorus (P) beyond maintenance level in the ration of goats had no positive influence on either growth rate or nutrients utilization. However, feed conversion efficiency was found best in the treatment T2 where Ca and P ratio was 2.65:1 in the ration of Baberi kids.
