细毛羊放牧春秋季采食量的差异研究
The Feed Intake Differences of Fine-wool Sheep Grazing in Spring and Autumn
摘要
Abstract
[Objective] The level of feed intake is an important factor that affects the performance of grazing livestock production.[Method] Xinjiang fine-wool sheep grazing conditions were taken as the test subjects to measure spring and autumn forage nutrients,and the total feces collection method and foreign aid indicator method were applied to measure the sheep feed intake in order to compare differences between different seasons and different methods.[Result] The total feces collection method measured the defecation in spring and autumn were 843.15 ±0.17 and 1 147.81 ±0.14 g · d,foreign aid indicator measurement were 807.39 ±0.28 and 1 090.42 ±0.23 g · d,the difference was not significant (P >0.05).391.57 ± 230.40 and 2 107.62 ± 170.42 (g/d-1) in spring and autumn sheep grazing feed intake were highly significant (P <0.01),the difference between the two quarters; forage dry matter digestibility was(39.41 ±0.16)% and (45.54 ± 0.01)%,the difference between the two quarters was extremely significant (P < 0.01).[Conclusion] The difference of the fecal output of grazing sheep measured by total feces collection method and foreign aid indicator method was not significant,and foreign aid indicator method could replace the total feces collection method to measure the sheep fecal output.There is a great difference between different seasons forage nutrients and feed intake.关键词
