The average participant gained 3.35 pounds every four years, for a total weight gain of 16.8 pounds in 20 years.
Daily weight gain, total weight gain, feed intake, and feed conversion were not affected by Se-yeast supplementation.
There were differences (p = 0.01 0.03) between diets in final body weight (BW), total weight gain (WG), daily weight gain (DWG) and specific growth rate (SGR) (Table 4).
Total weight gain (kg) from mating to weaning increased linearly as feeding level increased (L: 30.5, M: 36.3, H: 48.7; P<0.05).
However, lambs final weight, total weight gain and ADG increased linearly (P < 0.05) as levels of both β-adrenergic agonist increased.
Final body weight, total weight gain, daily weight gain and feed efficiency of the high wheat straw diets were significantly (P < 0.05) better than low wheat straw diets.
The cottonseed cake levels in substitution of soybean meal also did not affect final body weight, daily weight gain and total weight gain of the lambs (P > 0.05).
Total weight gain of MG calves was greater than that of LG calves and tended to be greater in MG-S calves than in MG-C calves.
Neither feeding regimen nor period had any significant effect (P > 0.05) on final BW, total weight gain, average daily gain and dry mater intake.
There were differences (p < 0.05) among diets in final body weight, total weight gain, daily weight gain, specific growth rate, viscera-somatic weight (VSI%), hepato-somatic index (HIS%) and intra-peritoneal fat (IPF%).
Increasing level of zilpaterol supplementation increased total weight gain (linear component, P < 0.05), gain:feed (linear component, P < 0.01), and dressing percentage (linear component, P < 0.02), and decreased (linear component, P < 0.01) kidney-pelvic fat.
