Dietary ratio of linoleic to alpha-linolenic acid affects the reproductive performance of Japanese quail.
1. This study was conducted to assess the effects of different dietary omega 6:3 ratios fed to male and female Japanese quail breeders on incubation performance, chick quality and progeny performance.2. A completely randomised design was used, with five diets containing different ratios of vegetable oils rich in linoleic acid (LA from soybean oil) or α-linolenic acid (ALA from linseed oil) with LA/ALA ratios of 13.75:1, 10.69:1, 7.63:1, 4.57:1 and 1.48:1 with 12 cage replicates containing six birds each.3. There was a quadratic effect of the LA/ALA ratio on total hatchability (p < 0.011), fertile hatchability (p = 0.046) and total mortality (p = 0.046). There was no effect on fertility (p > 0.05). The LA/ALA ratios of 1.48 and 13.75 fed to both hens and cockerels or hens resulted in greater fertility, as measured by the number of days after copulation during which fertile eggs were laid and the number of points of hydrolysis on the perivitelline membrane. A decreasing linear effect (p < 0.0001) was observed on chick length and an increasing linear effect on body weight at 1 day of age. There were no effects on progeny performance.4. The LA/ALA ratio affected yolk mineral matter (p = 0.009), crude protein (p = 0.091), chick mineral matter (p < 0.038) and ether extract (p < 0.0001) contents. Maternal diet affected the fatty acid profile of egg yolk and chick liver, indicating that dietary contents were transferred to eggs and chicks.5. Fertile egg production increased with lower LA/ALA ratios. Therefore, linseed oil can be used together with soybean oil to formulate diets for female Japanese quail obtain LA/ALA ratios between 4:1 and 10:1.
期刊介绍:
From its first volume in 1960, British Poultry Science has been a leading international journal for poultry scientists and advisers to the poultry industry throughout the world. Over 60% of the independently refereed papers published originate outside the UK. Most typically they report the results of biological studies with an experimental approach which either make an original contribution to fundamental science or are of obvious application to the industry. Subjects which are covered include: anatomy, embryology, biochemistry, biophysics, physiology, reproduction and genetics, behaviour, microbiology, endocrinology, nutrition, environmental science, food science, feeding stuffs and feeding, management and housing welfare, breeding, hatching, poultry meat and egg yields and quality.Papers that adopt a modelling approach or describe the scientific background to new equipment or apparatus directly relevant to the industry are also published. The journal also features rapid publication of Short Communications. Summaries of papers presented at the Spring Meeting of the UK Branch of the WPSA are published in British Poultry Abstracts .
