摘要

这项研究分两个阶段进行。第一阶段研究以哺乳仔猪为试验对象,然后以43日龄的断奶仔猪为试验对象。第二阶段为育肥期43 ~ 165日龄仔猪。试验采用2 ~ 3胎母猪两组进行试验。对照组(C)饲喂标准饲料,试验组(E)饲喂标准饲料,在标准饲料中添加0.3 kg/t的“EnzActive Mix”饲料添加剂。哺乳仔猪从5日龄开始饲喂预发酵剂,直至断奶。E组饲喂试验饲料添加剂,添加量为500 g/t。生长期断奶仔猪继续食用预发酵剂饲料。43 d后,E组仔猪在标准饲料中添加0.3 kg/t的“EnzActive Mix”饲料添加剂。结果表明,在33 d的试验期间,母猪的活重分别降低了25 kg (C)和20 kg (E),降幅达2.44% (P<0.001)。E组初龄仔猪第28天的活重比C组提高了15.28%,差异有统计学意义(P<0.001)。生长第14 d时,E组仔猪的活重较C组显著增加(P<0.001),增幅达12.61%。E组仔猪平均日增重提高7.14% (P<0.001),证实了E组仔猪活重的提高。试验第二阶段(育肥)表明,添加“EnzActive Mix”饲料添加剂后,E组43 ~ 80日龄平均体重比C组提高15.38% (P<0.001),活重提高14.55% (P<0.001)。我们发现,E组的平均日增重提高了17.27% (P<0.001),这表明与C组相比,获得1公斤增重的饲料成本降低了14.61%。第2育肥期(81 ~ 118 d), E组活重比C组提高了15.4% (P<0.001),活重增重和平均日增重提高了17.94% (P<0.001),每千克增重的饲料成本降低了15.38% (P<0.001)。在育肥第3期(119 ~ 165 d), E组每kg增重的采食量极显著降低9.06 (P<0.001),活重和平均日增重提高9.86% (P<0.001)。

Efficacy of “EnzActive mix” feed additive in piglet growing
The study was conducted in two stages. The first stage of study was carried out on lactating sows with suckling piglets, and then on weaned piglets up to 43 days of age. The second stage was carried out on young pigs from 43 to 165 days of life during fattening stage. For the study, two groups of sows of the 2–3 farrow were formed. The sows of the control group (C) were fed standard feed, and the experimental group (E) received standard feed with the addition of the “EnzActive Mix” feed additive in the amount 0.3 kg/t of feed. The suckling piglets received pre-starter feed from 5 days of age until weaning. The E group received the experimental feed additive in the amount of 500 g/t. Weaned piglets in the growing period continued to consume pre-starter feed. After the 43 day of life, the piglets in E group received the “EnzActive Mix” feed additive in the amount of 0.3 kg/t to the standard feed. It was found that during the experiment, which lasted 33 days, the live weight of sows decreased by 25 kg (C) and by 20 kg (E), which is 2.44% less (P<0.001). In the early age piglets in E group, there was a statistically significant increase in live weight on day 28 (P<0.001) or by 15.28% compared to C group. After fourteen days of growing, the piglets of E group had a significant increase in live weight (P<0.001) or 12.61%, compared to C group. The increase in live weight in E group is confirmed by the piglets average daily gain rise on 7.14% (P<0.001). The second (fattening) stage of the experiment showed that after adding the “EnzActive Mix” feed additive, from 43 to 80 days of life the average weight in the E group was 15.38% (P<0.001) higher than in C group, and also the increase in live weight by 14.55% (P<0.001) was admitted. We found out an increase in average daily weight gain by 17.27% (P<0.001) in the E group, pointing that the cost of feed to obtain 1 kg of weight gain was lower by 14.61% comparing to the C group. In the second fattening period from 81 to 118 days of life, the live weight in E group increased by 15.4% (P<0.001), live weight gain and average daily weight gain increased by 17.94% (P<0.001), compared to C group, whereas the feed costs per 1 kg of weight gain decreased by 15.38% (P˃0.001). In the third period of fattening, which lasted from 119 to 165 days of life, the feed consumption per 1 kg of weight gain in E group was significantly lower by 9.06 (P˃0.001), and an increase in live weight and average daily weight gain by 9.86% (P<0.001) was noted.
