This study was conducted to investigate the effect of malic acid and 20% palm kernel meal (PKM) on ruminal characteristics. A total of 32 growing lambs were randomly distributed into control (barley and alfalfa ha), total mixed ration (T1), TMR + 20% PKM (T2), TMR + PKC 20% + 4 mL/day malic acids (T3). Lambs were fed these diets ad libitum for 84 days. The results showed that propionic acid in the rumen fluid increased significantly ( < 0.05) in T1 and T3. Lactic acid concentration of rumen fluid increased significantly ( < 0.05) in T2 while the pH increased significantly. The coloration of rumen and reticulum was improved in T3. In addition, most of the histomorphological features were higher in T3 and T2. We concluded that the addition of malic acid supplementation to lambs fed PKC caused a significant improvement in the rumen pH and decreased lactic acid concentration in growing Naemi lambs.
本研究旨在探讨苹果酸和20%棕榈仁粕(PKM)对瘤胃特性的影响。总共32只生长羔羊被随机分为对照组(大麦和苜蓿干草)、全混合日粮组(T1)、TMR + 20% PKM组(T2)、TMR + 20% PKC + 4毫升/天苹果酸组(T3)。羔羊自由采食这些日粮84天。结果表明,T1组和T3组瘤胃液中的丙酸显著增加(<0.05)。T2组瘤胃液中的乳酸浓度显著增加(<0.05),而pH值显著升高。T3组瘤胃和网胃的色泽得到改善。此外,T3组和T2组的大多数组织形态学特征更高。我们得出结论,在饲喂PKC的羔羊中添加苹果酸可显著改善瘤胃pH值,并降低生长中的纳伊米羔羊的乳酸浓度。
