The experiment was conducted to find out the effect of four feeding systems namely; stall feeding, tethering, restricted grazing and grazing on carcass characteristics of Black Bengal goat. Twenty four does of approximately 1 year of age were randomly selected for four treatments of feeding systems having 6 replications in each. Stall fed goats were kept into house all time and adequate amount of natural grass were supplied for ad libitum feeding. Goats of tethering group were tethered for eating natural grass from 8 a.m. to 4 p.m. and were transferred after one hour interval for changing the grazing place. Goats of restricted grazing group were allowed for grazing from 8 a.m. to 1 p.m. Goats of grazing group were grazed for 8 a.m. to 4 p.m. Concentrate supplement was given at the rate of 150 g per day per goat for all of the treatment groups. Goats were slaughtered after the experiment of 219 days. Body length and height at wither were significantly higher in stall feeding group than others. Average dressing percentage were 42.18, 39.0, 36.79 and 34.0 for stall feeding, tethering, restricted grazing and grazing groups, respectively. Dressing percentage varied significantly (p<0.05) among feeding groups. Caul fat and empty gut weight differed significantly (p<0.05) in all of the feeding systems but others non-carcass parameters did not differ significantly. Percentage of dry matter and ether extract were also significantly (p<0.05) higher in stall fed groups. In conclusion, among four treatment groups, performance of stall fed goats were most satisfactory and then tethering showed better performance than any other groups. |
