STUDY ON LYSINE REQUIREMENT OF LACTATING SOWS
摘要
Abstract
Thirty Large White×Landrace×Beijing Bla ck lactating(LW×LR×BB) sows were divided into three groups and were fed three di ets containing respectively 0.60％(Ⅰ)，0.8 0％(Ⅱ)，1.00％(Ⅲ) lysine to study the effec ts of dietary lysine levels on sow perfo rmance，blood and milk biochemical indexe s，and to estimate the appropriate dietar y lysine level in lactation diets．The re sults were as follows：The lysine levels in lactation diets h ad an unsignificant effect (P＞0.10) on sow body weight changes，feed intake at 21 days of lactation and dura tion (days) from weaning at day 21 of la ctation to estrus for LW×LR×BB．There was no remarkable difference( P＞0.05) on the average litter size and d iarrhea frequency at day 21 of lactatio n．Litter weight at day 21 increased ( P＜0.06) as dietary lysine increased．Simi lar effects were observed for litter wei ght gains from day 0 to 7( P＜0.06)，day 0 to 14 ( P＜0.03) and day to 21 ( P＜0.01)．At day 14 of lactation，milk protein was higher ( P＜0.01) in group Ⅱ，Ⅲ than those in group Ⅰ．DM was higher ( P＜0.05) in group Ⅱ than that in group Ⅰ． At day 21 of lactation，DM was higher ( P＜0.05) in group Ⅱ than that in group Ⅰ． At day 14 of lactation，serum urea nitrog en (SUN) in group I was higher ( P＜0.05) than in group Ⅱ and Ⅲ．At day 21， SUN in group I was higher ( P＜0.01) than that in group Ⅱ and Ⅲ．ALB i n group Ⅱ was higher ( P＜0.05) than that in group Ⅰ． The results suggested that lysine level in the lactating diets should be 0.80％－1 ．00％．关键词
