Effectiveness of high input feeding system in relation to growth and carcass quality of various classes of Beetal kids.

High input feeding system results in better growth performance in goats as compared to low input feeding system. Traditionally goats are reared under low input system while to see the effectiveness of high input feeding system, current project was planned to study the growth performance and carcass quality among various classes of Beetal breed. Total 16 Beetal kids (12 male +4 female) were selected considering 120 (+/- 10) days average age and weight ranging 16 (+/- 2) kg for male and 14(+/- 2) kg for female. The kids from various classes were divided into four treatment groups designated as S1 (Entire male or not castrated), S2 (castrated at 4 mo), S3 (castrated at 6 mo) and S4 (female). Animals were castrated during pre-fattening period and managed under same conditions before fattening. The duration of the study was 120 days (60 days pre-fattening + 60 day fattening). Total 12 animals (randomly 3 from each treatment group) were slaughtered at the end of study for detail carcass quality evaluation. The average daily gain (ADG) was significantly affected (P<0.001) by the treatments. There was higher ADG noticed in S3 group (93.75 gm/d) as compared to S1 (90.42 gm/d), S4 (63.89 gm/d) and S2 (33.75 gm/d). Average daily feed intake was significantly (P<0.05) highest in S3 (878.00 gm/d). The serum cholesterol and serum glucose were also affected (P<0.05) by the treatments. There was non-significant (P>0.05) effect of treatments on the sensory panel score about color, chewability, flavor, tenderness and overall acceptability of the cooked meat. It is concluded that sex and castration affected the growth in kids while the carcass traits were not affected. The age of castration need consideration in Beetal kids because castration at early age adversely affected the growth of kids in this study.
