Abstract:

The study was conducted to determine the effect of feeding lower crude protein with adequate levels of lysine and methionine in starter swine. A total of 18 starter piglets at 20 kg initial live weight were randomly distributcd to individual pens. The pigs were assigned to three diets with 18.0% (control), 17.1 %, and 16.2% CP in the diet. Each treatment had six replicatcs, arranged following a completely randomized design. Among the nutrients in the treatments, only the crude protein level was altered. At the end of the feeding trial at 40 kg live weight, average daily gain, average daily feed intake and feed conversion efficiency did not differ among treatments. Pigs given 16.2%) CP had higher (P
