摘要:选用120头生长猪,对4种不同来源的卡诺拉菜籽粕(canola meal)和1种大豆粕(soybean meal,SBM)日粮中添加不同水平的植酸酶,以研究其对磷(P)和钙(Ca)的表观全肠道消化率(apparent total tract digestibility,ATTD),以及P的标准全肠道消化率(standardized total tract digestibility,STTD)的影响。4种canola meal中,一种为高蛋白型,两种为传统型,且上述两种传统型中的一种在破碎前分成两批。试验猪(初始体重为16.2±5.3kg)单独饲养于代谢笼中,试验采用5×4因子设计,20个试验日粮随机分配为5个原料和4个植酸酶水平。每个日粮6个重复。5个基础日粮分别包含高蛋白卡诺拉菜籽粕(high-protein canola meal,CM-HP),高温处理后的卡诺拉菜籽粕(high-temperature processed canola meal,CM-HT),低温处理后的卡诺拉油菜籽(low-temperature processed canola meal,CM-LT),传统卡诺拉菜籽粕(conventional canola meal,CM-CV)和大豆粕(SBM)。基础日粮中均不含植酸酶。5个基础日粮分别添加大约500、1500、2500 FTU/kg植酸酶,形成另15个处理组。经7天适应期之后,使用“指示剂至指示剂(marker-to-marker”)的方法,连续收集5天粪便。结果显示,添加植酸酶可线性提高(P < 0.05) CM-HP,CM-HT,CM-CV和SBM试验组中Ca的ATTD,但对CM-LT无显著影响。植酸酶也增加(线性和二次,P < 0.05)了5种原料中P的ATTD和STTD。相对于CM-CV,CM-HP中Ca的ATTD较高(P < 0.05)。对Ca的ATTD这一指标,SBM试验组均比所有菜籽粕都高(P < 0.05),而CM-HT与CM-LT之间差异不显著。对于P的ATTD和STTD,在无植酸酶添加的情况下,CN-HP,CM-HT,CM-LT比SBM低(P < 0.05),但当植酸酶以最高剂量添加时,SBM,CM-HP,CM-HT和CM-CV之间无显著差异(P < 0.05)。植酸酶与CN-HP,CM-HT,CM-LT,CM-CV组P的STTD之间可建立回归方程。综上,通过添加植酸酶可提高CM-HP,CM-HT,CM-LT,CM-CV和SBM中P的ATTD及STTD,并且,各原料植酸酶的添加效果可由回归方程进行预测。

ABSTRACT: One hundred twenty pigs were used to determine effects of graded levels of microbial phytase on the apparent total tract digestibility (ATTD) of P and Ca and the standardized total tract digestibility (STTD) of P in 4 sources of canola meal and in 1 source of soybean meal (SBM) fed to growing pigs. The 4 sources of canola meal were produced from 1 source of high-protein canola seeds and 2 sources of conventional canola seeds with 1 of the conventional canola seeds being divided into 2 separate batches before crushing. Pigs (16.2 ± 5.3 kg initial BW) were individually housed in metabolism crates and were randomly allotted to 1 of 20 diets in a 5 × 4 factorial arrangement of treatments with 5 ingredients and 4 levels of phytase. There were 6 replicate pigs per diet. Five basal diets based on high-protein canola meal (CM-HP), high-temperature processed canola meal (CM-HT), low-temperature processed canola meal (CM-LT), conventional canola meal (CM-CV), or SBM were formulated. The basal diets contained no phytase. Fifteen additional diets were prepared by adding approximately 500, 1,500, or 2,500 phytase units/kg to each of the 5 basal diets. Feces were quantitatively collected for 5 d based on the marker-to-marker approach after a 7-d adaptation period. Results indicated that supplementation of microbial phytase increased (linear, P < 0.05) the ATTD of Ca in diets containing CM-HP, CM-HT, CM-CV, and SBM but not in diets containing CM-LT. Microbial phytase also increased (linear and quadratic, P < 0.05) the ATTD and STTD of P in all 5 ingredients. Compared with the CM-CV diets, the CM-HP diets had greater (P < 0.05) ATTD of Ca. The ATTD of Ca in the SBM diet was greater (P < 0.05) than in all canola meal diets, but no differences were observed in ATTD of Ca between CM-HT and CM-LT diets. The ATTD and the STTD of P were less (P < 0.05) in CM-HP, CM-HT, CM-LT, or CM-CV than in SBM if no microbial phytase was added, but no differences were observed in the ATTD and STTD of P in SBM, CM-HP, CM-HT, or CM-CV if the highest amount of phytase were added (interaction, P < 0.05). Regression equations were developed to calculate the response to microbial phytase on the STTD of P in CM-HP, CM-HT, CM-LT, CM-CV, and SBM. In conclusion, inclusion of graded levels of microbial phytase increased the ATTD and STTD of P in CM-HP, CM-HT, CM-LT, CM-CV, and SBM and the response to microbial phytase added to each ingredient can be predicted by regression equations.
