【摘要】：本试验旨在使用线性回归法和差量法研究基础饲粮类型对生长猪氨基酸回肠真消化率(TID)的影响。选用32头初始体重为(28.9±0.7)kg安装了简单T型瘘管的生长公猪,采用有重复的8×2不完全拉丁方设计,8种试验饲粮,进行2期消化试验。8种试验饲粮包括2种基础饲粮类型(玉米淀粉组和玉米组)和4种豆粕添加水平(0,13%,26%和39%)。每期消化试验包含7d,其中5d的饲粮适应期和2d的回肠食糜收集期。结果表明,除赖氨酸、精氨酸和脯氨酸外,以玉米为主的基础饲粮中回肠总氮和氨基酸排泄量显著高于以玉米淀粉为主的基础饲粮(P0.01)。除脯氨酸外,生长猪回肠总氮和氨基酸排泄量随饲粮豆粕添加水平提高呈线性显著增加(P0.01)。使用差量法测定氨基酸TID时,以玉米为主基础饲粮中总氮和甘氨酸的TID显著高于以玉米淀粉为主的基础饲粮(P0.05),但玉米淀粉为主的基础饲粮中蛋氨酸和赖氨酸TID显著高于玉米为主的基础饲粮(P0.05),基础饲粮类型对其他氨基酸TID无显著影响(P0.05)。使用线性回归法测定氨基酸TID时,生长猪饲喂以玉米淀粉为主的基础饲粮和以玉米为主的基础饲粮对总氮和氨基酸的TID均无显著差异(P0.05)。由此可见,生长猪对总氮和氨基酸TID的测定不受基础饲粮类型的影响。
[Abstract]:The purpose of this study was to use linear regression method and difference method based on the type of diet for growing pigs of true ileal digestibility of amino acids (TID). The effect of using 32 head initial body weight (28.9 + 0.7) kg installed growingboars simple type T fistula, with repeat 8 * 2 incomplete Latin square design. The 8 test diets, 2 kinds of.8 digestion test diets including 2 diet types (corn starch and corn group group) and 4 levels (0,13%, 26% soybean meal and 39%). Each digestion test contains 7d, the 5D diet adaptation period and 2D period of ileal digesta were collected. The results showed that in addition, lysine, arginine and proline, total nitrogen and ileal amino acid excretion in the basal diet of corn based diet was significantly higher than that of corn starch based (P0.01). Except for proline, with soybean meal diet add water to grow pig ileum total nitrogen and amino acid excretion Improvement linearly increased significantly (P0.01). Using differential method for the determination of amino acids in corn TID, total nitrogen and glycine basal diet TID was significantly higher than that of the basal diet with corn starch based (P0.05), but the basal diet of corn starch mainly in methionine and lysine TID were significantly higher than that of corn based diets. The (P0.05), basal diet had no significant effect on other types of amino acid TID (P0.05). Using the linear regression method for determination of amino acids of TID, there were no significant differences in basal diet of growing pigs fed with corn starch and the corn based diet on total nitrogen and amino acids of TID (P0.05). Thus, the growth of pigs determination of total nitrogen and amino acid of TID was not affected by diet type.
