Abstract:
The present study was conducted to observe the growth performance of Beetal goat kids feeding on different plan of nutrition under stall fed condition. Three concentrate mixtures having 22, 24.2 and 26.4 percent crude protein and 71, 78.10 and 85.2 percent TDN were prepared with conventional ingredients available in Goat Research Station, AAU, Byrnihat. Twelve weaned male Beetal kids were divided randomly on the basis of live weight into three experimental groups (C, T₁ and T₂) of four animals in each group. Kids belongs to group C, T₁ and T₂ were fed a mixture of para and Napier grass (1:1 on DM basis) and respective concentrate mixture C, T₁ and T₂ in the ratio 40:60 on DM basis to meet the 100, 110 and 120 percent of nutrient (CP, DCP and TDN) requirement as per ICAR (2013) standard for growing male goats under tropical condition for a period of 84 days during which the change in body weight of kids were recorded fortnightly. In the last week of the feeding trial a digestion trial was conducted for duration of 5 days for evaluation of nutrient utilization by the kids of different groups. At the end efficiency of feed utilization, Feed conversion efficiency and economics of the feeding was calculated. The average daily gain found are 69.28^a±2.96, 74.76^ab±2.57 and 83.69^b±4.46 in group C, T₁ and T₂ respectively during entire feeding trial. The total DM intake (kg/animal) were 36.53±0.50, 38.48±0.89 and 44.78±0.79 in C, T₁ and T₂ groups, respectively. The feed conversion efficiency (on DM basis) in the experimental groups during entire feeding trial were 6.28±0.63, 6.13±0.39 and 6.36±0.58 in C, T₁ and T₂ groups, respectively. At last it was concluded that 100 percent recommendation of nutrient requirements (DCP & TDN) suggested by ICAR (2013) is appropriate for a satisfactory growth of Beetal goats under hot humid agro-ecological climatic condition of Assam and Other states of North East, India. However for better growth performance Beetal kids may be reared on higher protein and energy level up to 120 percent of ICAR (2013) recommendation.
