摘要

目前的研究是4 × 4拉丁方设计的大型实验的一部分,其中检查了4种膳食处理(饲料补充剂)。粪便标本采用全收集法(实验1,n = 30;实验2,n = 16)。对饲料和粪便样品进行酸性洗涤不消化灰分(ADIA)和营养物质分析,并以此估算粪便排泄量(FO)和营养物质消化率。每个试验的数据采用SAS混合程序进行分析,以确定饲粮、方法(实际与ADIA估算),以及它们对脂肪含量和营养物质表观全消化道消化率的相互作用。并对实测与ADIA估计的FO进行了线性回归。在两个实验中,ADIA的回收率均为106%。使用ADIA倾向于低估鱼油5% (Exp. 2, p=0.09),高估营养物质消化率2% ~ 5% (Exp. 1, p≤0.08)。线性回归的斜率为0.80(对1,p=0.02),截距为1.93(对0,p=0.21)。综上所述,经回归分析得到的因子校正后,ADIA可作为估算乳牛粗脂肪的潜在指标。

Estimating fecal output and nutrient digestibility using acid detergent insoluble ash as an intrinsic marker in lactating dairy cows: technical note.

The current study was part of large experiments in a replicated 4×4 Latin square design where 4 dietary treatments (feed supplements) were examined. Fecal samples were obtained from the experiments via total collection (Experiment 1, n = 30; Experiment 2, n = 16). Feed and fecal samples were analyzed for acid detergent insoluble ash (ADIA) and nutrients, and those were used to estimate fecal output (FO) and nutrient digestibilites. Data within each experiment were analyzed using the Mixed procedure of SAS to determine diet, method (actual vs. estimated by ADIA), and their interaction on FO and apparent total tract digestibility of nutrients. A linear regression for FO between actual and estimated by ADIA was also conducted. The recovery of ADIA was 106% in both experiments. The use of ADIA tended to underestimate FO by 5% (Exp. 2, p = 0.09) and overestimate nutrient digestibilities by 2% to 5% (Exp. 1, p≤0.08). The linear regression resulted in the slope of 0.80 (against 1, p = 0.02) and the intercept of 1.93 (against 0, p = 0.21). In conclusion, ADIA is a potential marker for lactating cows in estimating FO when corrected by the factor obtained from the regression analysis.
