摘要: The effects of dietary protein and lysine levels on lactating multiparous sows and litter performance were studied. Sixty-two crossbred multiparous sows (LandraceXYorkshire) were used. Thirty-three and twenty-nine sows were studied in their second parity and third parity respectively. The three dietary treatments were: (1) the control diet containing 15% CP and 0.75% lysine, (2) a diet containing 13% CP and 0.75% lysine (0.60% natural+0.15% synthetic), and (3) a diet containing 13% CP and 0.60% lysine. They were fed twice daily and allowed ad libitum access to food and water throughout a 28 day lactation from parturition until weaning. The results of this experiment showed that body weight and backfat losses of the sows from farrowing to weaning were significantly affected (p<0.01) by reducing dietary protein. Neither average daily feed intake nor weaning to estrus interval of sows were significantly different among treatments. Supplementing lower dietary protein with synthetic lysine could mitigate backfat losses, but could not prevent body weight losses in lactating multiparous sows. A corn-soybean meal diet containing 13% crude protein and 0.60% lysine did not significantly affect litter size and survival rate of weanling piglets compared with the 15% crude protein diet. There was a tendency towards decreased piglet weight at weaning (p<0.10) and reduced daily gain of piglets (p<0.11) when the multiparous sows were fed the 13% protein diet during lactation. We found a severe loss of body weight and backfat when reducing dietary protein for lactating multiparous sows.
