High Level of Copper for Suckling pigs |
| |
| Abstract: | 145 suckling pige ( Landrace × Rongchang ) from 20 to 60 d of age were used in a feeding trial to study the effect of high level of copper supplementation on performance. Results showed that average daily gain ( ADG ) and digestible energy ( DE ) requirements during the 40-d experimental period were as follows: 306, 307, 318 and 374 gms and 6.70, 6.77, 6.73 and 6.48 Meal per kg of gain for the o, 60, 125 and 250 ppm Cu supplemented group-s, respectively. ADG of the 250 ppm Cu supplemented pigs was 13.4% higher than that of the control and DE/gain, 3.3% lower. Mean blood hemoglobin values were 9.5, 10.1, 10.0, and 9.70 gms/100 ml for the 0, 60, 125 and 250 ppm Cu supplemented pigs, respectively. |
