Description |
The feed restriction either in male or female broilers with out consideration of diets provided during 2nd or 3rd week of age by 10 and 20 per cent to that of ad libitum feeding did not affect the final 6th week body weight, feed consumption and feed efficiency. The male broilers recorded a marginally higher final weekly weight gain. Whereas, female broilers recorded significantly better weight gain in final week. The different diets irrespective of feeding schedule in male broilers showed non-significant difference at final body weight, weekly weight gain and feed efficiency. Whereas, female broilers recorded better body weight in high energy diets but did not reveal any significant difference in final week weight gain and feed efficiency. Both male and female broilers recorded significantly (P0.05) lower feed consumption in high energy diets. Better livability and no incidences of skeletal deformities were recorded in feed restricted groups. The variation in dietary profile had no severe impact on livability and skeletal deformities. The carcass characteristics and abdominal fat weight was unaffected due to feed restriction and variation in dietary profile either in male or female broilers. Interaction effect on body weight, weekly weight gain, feed consumption, feed efficiency, carcass characteristics, abdominal fat weight, livability and skeletal deformities of different feeding schedules and diets were non-significant. Ten per cent feed restriction to ad libitum feeding during 2nd week increased the net profit per bird compared to ad libitum fed control group in both male and female broilers. Upon variation in dietary profile Diet 1 (low energy-high protein) and Diet 4 (high energy-low protein) recorded maximum net profit per bird in male and female broilers respectively. Based on the present study, ten per cent feed restrictions during second week of age is recommended for the broiler industry |
