【摘要】：本試驗旨在研究碘醚柳胺驅(qū)蟲對6月齡伊犁馬駒營養(yǎng)物質(zhì)消化代謝及生長發(fā)育的影響。試驗選取在同一草場飼養(yǎng)的6月齡(出生日期±5 d)、平均體重為(117.60±15.84)kg的伊犁馬公馬馬駒10匹,在相同的飼喂條件下隨機(jī)分為2組,分別為對照組和試驗組,每組5匹。試驗組馬駒灌服碘醚柳胺混懸液驅(qū)蟲劑驅(qū)蟲,每匹14 m L,對照組馬駒不進(jìn)行驅(qū)蟲。驅(qū)蟲后,進(jìn)行為期20 d的消化代謝試驗,其中預(yù)試期15 d,正試期5 d。結(jié)果顯示:碘醚柳胺驅(qū)蟲對馬駒各營養(yǎng)物質(zhì)攝入量、消化量、排出量和消化率均沒有產(chǎn)生顯著影響(P0.05),但試驗組中性洗滌纖維、酸性洗滌纖維、鈣消化率分別比對照組高18.17%、16.37%、17.36%;試驗組馬駒氮的沉積量和沉積率分別比對照組高65.90%(P0.05)和73.20%(P0.05);試驗組馬駒體高和胸圍的總增長分別比對照組高123.58%(P0.05)和48.31%(P0.05)。因此,碘醚柳胺驅(qū)蟲對6月齡伊犁馬營養(yǎng)物質(zhì)消化代謝的積極作用主要體現(xiàn)在氮沉積量和沉積率的增加以及體高和胸圍的增長上。
[Abstract]:The purpose of this study was to study the effects of iodide willow amine on the digestion, metabolism, growth and development of nutrients in 6-month-old Yili foal. Ten Yili ponies with an average weight of (117.60 鹵15.84) kg at 6 months of age (birth date 鹵5 d),) were randomly divided into two groups under the same feeding conditions: control group (n = 5) and experimental group (n = 5). The foals in the experimental group were treated with iodoetheralumide suspension repellent, 14 mL each, while the control foal was not treated with deworming agent. After deworming, the digestion and metabolism test was carried out for 20 days, in which the pre-trial period was 15 days and the positive test period was 5 days. The results showed that iodide had no significant effect on the intake, digestion, excretion and digestibility of nutrients in foals (P 0.05), but the digestibility of neutral detergent fiber, acid detergent fiber and calcium in the experimental group was 18.17%, 16.37% and 17.36% higher than that in the control group, respectively. however, the digestibility of neutral detergent fiber, acid detergent fiber and calcium in the experimental group was 18.17%, 16.37% and 17.36% higher than that in the control group. The nitrogen deposition and deposition rate of foal in the experimental group were 65.90% (P 0.05) and 73.20% (P 0.05) higher than those in the control group, and the total increase of body height and chest circumference in the test group were 123.58% (P 0.05) and 48.31% (P 0.05) higher than those in the control group, respectively. Therefore, the positive effect of iodide on the digestion and metabolism of nutrients in 6-month-old Yili horses was mainly reflected in the increase of nitrogen deposition and deposition rate, as well as the increase of body height and chest circumference.
