Abstract

A series of feeding trials lasting 21 days was conducted with Large White turkey poults to determine the effects of 0, 12.5, and 25% energy as 1,3-butylene glycol (BG) on growth and on both in vivo and in vitro lipogenesis. The substitution of 12.5 and 25% of the energy as BG and on both in vivo and in vitro lipogenesis. The substitution of 12.5 and 25% of the energy as BG depressed growth and feed efficiency of 21-day-old poults (P less than 01). The relative liver size was increased by BG (P less than .01) while liver lipid per 100 g of body weight was decreased (P less than .01) by BG. IN vivo lipogenesis, determined by the incorporation of tritiated water into liver fatty acids was decreased (P less than .05) by BG. The evolvement of CO2 from both (1-14C) acetate and from (U-14C) glucose was decreased by BG. The results of this study indicate that while lipogenesis can be decreased by BG, growth is also decreased. Therefore, the regulation of growth parallels the regulation of lipid synthesis in the turkey poult.

摘要

用大白火鸡雏进行了一系列为期21天的饲养试验，以确定作为1,3 - 丁二醇（BG）的0%、12.5%和25%能量对生长以及体内和体外脂肪生成的影响。用BG替代12.5%和25%的能量对体内和体外脂肪生成均有影响。用BG替代12.5%和25%的能量会降低21日龄雏鸡的生长和饲料效率（P<0.01）。BG会增加相对肝脏大小（P<0.01），而每100克体重的肝脏脂质则会因BG而减少（P<0.01）。通过将氚水掺入肝脏脂肪酸来测定的体内脂肪生成因BG而减少（P<0.05）。BG会降低（1-14C）乙酸盐和（U-14C）葡萄糖的二氧化碳释放量。本研究结果表明，虽然BG可降低脂肪生成，但生长也会降低。因此，火鸡雏鸡生长的调节与脂质合成的调节相似。
