山羊全混合日粮颗粒饲料适口性及贮存期研究

The research of feed palatability and storage of goat TMR pellet

试验对山羊全混合日粮颗粒饲料适口性和贮存期进行了研究,结果表明:山羊全混合日粮颗粒饲料适口性良好,27头20 kg左右育肥波尔山羊自由采食,日喂2餐,平均日采食量为(0.854±0.031)kg/只;日喂3餐,平均日采食量为(0.978±0.031)kg/只;日喂4次,平均日采食量(0.976±0.029)kg/只;日喂料3次以上较2次喂料可提高山羊采食量14.3%。水或水蒸汽调质使羊全混合日粮颗粒料保质期大大缩短;不调质直接采用冷制粒加工,羊全混合日粮颗粒料的保存期可达到3个月以上,但制粒产量低。羊全混合日粮制粒加工宜采用冷制粒,直接压制成型,不宜使用水或蒸汽调质;山羊全混合日粮颗粒料具有良好的适口性,适宜的加工条件可使用其贮存期达到3个月以上。

The test of goat pellets total mixed ration palatability and shelf life were studied. The results showed that： Goat total mixed ration pellet feed palatability good, about 27 20 kg fattening Boer Yangshan ad libitum, fed two meals a day; The average daily feed intake was （0.854±0.031） kg/sheep; 3 meals daily to feed, average daily feed intake was （0.978±0.031） kg/sheep; 4 times a day to feed, average daily feed intake （0.976±0.029） kg/sheep; Day feeding more than three times compared with the second goat feed intake can increase 14.3%. Water or steam tempered so that total mixed ration sheep pellets shortened storage period, Not directly quenched with cold granulation processing, preservation of sheep total mixed ration pellets can reach more than 3 months, but the low yield granulation. Sheep total mixed ration granulation process should be used cold granulation, direct compression molding, not to use water or steam tempered; goat total mixed ration pellets with good palatability, suitable processing conditions can use their storage period of 3 months.
