| Abstract;The present experiment aimed to examine the effects of controlled feeding (which is well known as a method for body fat deposition reduction) with low-CP feed on the growth and meat quality of fattening pigs. Feed used in this study was prepared by reducing CP level by 2.16% from the standard level during the fattening period according to the Japanese feeding standard for swine (1998), and by supplementing it with lysine. Fattening period, from 70kg to 115kg of body weight, was 41 days in the control, ad libitum, group, and 55 days in the experimental, controlled feeding, group. Although the feeding level of the controlled was designed to be 85% of the control group, it resulted at about 81%. Induced increase in the length of the fattening period increased feed intake and reduced feed efficiency. In the results of amino acid analysis, lysine and threonine intake was insufficient even in the control group. Those amino acids, sulfur-containing amino acids and branched-chain amino acids intake were also insufficient in the experimental group. The present results suggest that controlled feeding reduces the body fat deposition, although the amino acid imbalance might induce body fat deposition. (author abst.) |
