焙烤仔猪教槽料的研制

Study on the baked piglet feed

试验旨在研究仔猪焙烤教槽料生产工艺及其对仔猪诱食和生长性能的影响，开发出能够确保仔猪成功离乳的新型仔猪教槽料产品。通过对焙烤工艺优化，在焙烤温度170℃、焙烤时间18min时，焙烤产品赖氨酸损失最少，损失率为8．25％。诱食性试验证明，焙烤教槽料能使刚断奶仔猪采食速度明显加快；偏食性试验结果表明，在哺乳期7～20日龄内，焙烤教槽料的饲料摄入量是传统颗粒料的2倍；哺乳仔猪生产性能试验结果表明，在17～22日龄哺乳期间，焙烤教槽料日均饲料摄入量为11．1g／头，比传统颗粒料增加了10g／头，日均增重则比传统颗粒料增加了50g/头，显示出极高的饲料转化效率；焙烤教槽料在断奶第1d的采食量达到139．95g／头，是传统颗粒料的2倍，仔猪营养摄入量超过了维持的需要，不仅不会出现断奶失重现象，而且有增重。这些结果证明，焙烤过程中赖氨酸的损失得到有效控制，焙烤教槽料有效解决了仔猪在哺乳期不爱吃饲料、断奶初期失重的难题。

This paper aimed to research on the production process and feeding effect of baked piglet feed （BPF）, therefore to develop a novel piglet feed product to ensure the successful weaning. The bak- ing process was optimized at first. The loss ratio of lysine was minimum （8.25%） in the baked product when baking at 170 ℃ for 18 rain. Then the baked product was fed to piglets. The intake speed for the BPF was significantly increased. Meanwhile, the feed intake for the BPF was 2 times of that for the tra- ditional particulate feed （TPF）, testing with the suckling piglets at the age of 7 to 20 days. Furthermore, the growth performance of the BPF also improved greatly. When testing with the suckling piglets at the age of 17 to 22 days, the average daily feed intake for the BPF was 11.1 g/head, 10 times higher than that for the TPF, and the average daily weight gain was 50 g/head higher than that for the TPF, indicat- ing its high feed conversion ratio. Most importantly, for the piglets on day 1 postweaning, the feed in- take for the BPF reached 139.95 g/head, 2 times higher than that for the TPF, which means that the nu- trition intake exceeds the maintenance requirement, so piglets did not lose weight alter weaning, but gain weight. These results demonstrated that the loss of lysine in the baking process had been effective- ly controlled, anti two difficuh problems of unwilling to eat feed during suckling and lose of weight after weaning have been successfully solved by the BPF.
