你們認為母豬料需要添加「羥丁胺酸」嗎？

ABSTRACT: Reproductive performance is steadily increasing within the pork industry; logically, amino acid requirements need to be redefined for sows producing larger litters. The objective of this study was to determine the threonine requirement of the high-producing lactating sow and to determine the effect of lysine on this requirement. A total of 419 PIC C-15 sows were assigned randomly to treatment within parity groups (1, 2, and 3+) and gestation treatment at d 110 of gestation. Lactation diets were formulated to contain 0.80% total lysine (tLYS) with 0.30, 0.35, 0.40, 0.45, 0.50, 0.55, 0.60, or 0.65% total threonine (tTHR) or 1.06% tLYS with 0.40, 0.45, 0.50, 0.55, 0.60, 0.65, or 0.70% tTHR. Litters were standardized to a minimum of 11 piglets within 48 h after farrowing, and sows had free access to feed throughout lactation (lactation length = 20.1 ± 0.1 d). Sow ADFI exceeded expectation, averaging 6.90, 7.40, and 7.20 kg/d for Parities 1, 2, and 3+, respectively. Daily tLYS intake was 58 g/d (47 g of apparent ileal digestible lysine [dLYS] per day) and 74 g/d (59 g dLYS/d) for the low- and high-lysine group, respectively. Lysine intake did not affect sow or litter performance (P > 0.10). Sows gained an average of 4.8 kg in lactation. Using regression analysis, BW gain was maximized at 0.54% tTHR for all parity groups (quadratic; P < 0.05). Litter weaning weight (67.1, 67.9, and 66.2 kg for Parities 1, 2, and 3+, respectively) and litter weight gain (2.49, 2.53, and 2.44 kg/d for Parities 1, 2, and 3+, respectively) were maximized at 0.53% tTHR using regression analysis, for all parity groups (quadratic; P < 0.05). Based on regression analysis, plasma urea nitrogen on d 10 and 18 was minimized at 0.54% tTHR (P < 0.05). Lysine levels in excess of 58 g of tLYS/d did not benefit sow or litter performance. The requirement for threonine to minimize sow tissue mobilization was 37, 40, and 38 g tTHR/d (28, 30, and 30 g of apparent ileal digestible threonine [dTHR] per day) for Parities 1, 2, and 3+ sows, respectively. The threonine required to maximize litter performance was 36, 39, and 38 g of tTHR/d (28, 30, and 29 g of dTHR/ d) for Parities 1, 2, and 3+ sows, respectively. Alternatively, the requirement can be expressed as 14.3 g tTHR (11.8 g dTHR) per kilogram of litter gain.

羥丁胺酸很重要...影響很大
往往母前與母後很少會注意到羥丁胺酸的平衡
由其母前料
在自配戶中母前料是最不重視的
母豬群管理生產良好的人
對母前料非常重視

窩增重1公斤需要14.3公克總蘇胺酸(需要含0,54%總蘇胺酸的母後飼料2.65公斤)

這句話在臺灣如何應用呢?如下例;

臺灣夏季,哺乳母豬平均每日攝食量5.4公斤,哺乳21日,窩增重(6.5X9.5)-(1.5*10.8)=61.75-16.2=45.55
14.3公克X45.55=651.4公克
651.4公克/(21X5.4)=0574%(母後料夏季(驚蟄到白露)配方中蘇胺酸含量)
冬季配方,哺乳母豬平均每日攝食量7.2公斤,哺乳21日,窩增重(7.3X9.5)-(1.5*10.8)=69.35-16.2=53.15
14.3公克X53.15=760公克
760公克/(21X7.3)=0496%(母後料冬季(白露到驚蟄)配方中蘇胺酸含量)
