Canola and coconut oils in the feed of European quails (Coturnix coturnix)

ABSTRACT The objective of this study was to evaluate the effect of the inclusion of canola and coconut oils to diets of European quail (Coturnix coturnix) over performance and carcass yield. One hundred and ninety-two quail (eight-days old) were randomly allocated to four dietary treatments with six replicates of eight birds each. The treatments were arranged in a factorial 2×2 scheme with two sources of dietary oil containing two levels of canola and coconut oils (1 and 2%). For performance variables, the final weight was evaluated, and the carcass variables were feed intake, weight gain, and feed conversion. A significant difference was observed between treatments for feed intake, with the inclusion of 2% canola oil providing higher intake. There was also significant effect for carcass characteristics on weight at fasting, eviscerated carcass, liver and gizzard weights, as well as liver, heart, and gizzard yields. The inclusion of vegetable oil such as canola and coconut oils in diets for European quail at the levels of 1 and 2% can be performed with no negative effect on performance from 8 to 42 days of age.

摘要 本研究旨在评估在欧洲鹌鹑（Coturnix coturnix）日粮中添加菜籽油（canola oil）与椰子油（coconut oil）对其生产性能及屠宰性能的影响。试验选取192只8日龄欧洲鹌鹑，随机分为4个日粮处理组，每组设置6个重复，每个重复包含8只鹌鹑。试验采用2×2因子设计，设置2种油脂来源，菜籽油与椰子油的添加水平分别为1%和2%。针对生产性能指标，本研究测定了鹌鹑末体重；屠宰性能指标涵盖采食量（feed intake）、增重（weight gain）及饲料转化率（feed conversion）。各组处理间采食量存在显著差异，添加2%菜籽油组的采食量更高。屠宰特性指标方面，空腹体重、净膛重、肝脏与肌胃重量，以及肝脏、心脏与肌胃的屠宰率均表现出显著效应。在8至42日龄的欧洲鹌鹑日粮中添加1%和2%的菜籽油与椰子油等植物油，不会对其该阶段的生产性能产生负面影响。
