Abstract

This experiment was conducted to investigate the effect of different levels of SULFUR on the MICROBIAL PROTEIN production in male RAINI GOAT. Fifteen Raini male goats with mean body weight of 32±.7kg and 13-14 month of age were used. The trial was carried out using completely randomized design with 5 dietary treatments containing either 0.14, 0.22, 0.28, 0.34 or 0.4% SULFUR (DM basis). Each treatment had three replicates. The isocaloric and isonitrogenous diets were formulated according to AFRC (1998) recommendations. The metabolisable energy and the metabolisable protein of the diets were 9.57 (MJ/kg DM) and 8.42% respectively. Animals were kept in individual cages for 3 weeks and during the third week their urine sample were collected for the estimation of purine derivatives. The dry matter intake and live weight gain of the animals were measured. Additionally, the digestibilty of the dry matter and organic matter for the rations were determined. The in vivo digestibilityof dry matter and organic matter for the ration no.2 was the highest in comparisonto other diets. Also, the animals offered the level 0.22% SULFUR had the highest live weight gain among all the treatments. Results showed that the effect of different levels of SULFUR on MICROBIAL PROTEIN production and urinary purine derivatives were significant (P<0.01). MICROBIAL PROTEIN production in the diet containing 0.22% SULFUR was significantly (P<0.05)higher than other rations. Analysis of regression equations showed that there was a quadratic relationship between SULFUR and MICROBIAL PROTEIN production. The best level of SULFUR was 0.265%.
