Abstract
This study evaluated the effect of using lipid sources of plant and animal origin in diets for Japanese quail (Coturnix coturnix japonica) on production performance and internal egg quality. Japanese quails (n = 160) were distributed in a completely randomized design with four treatments and eight replications of five birds each. Lipid sources evaluated were: soybean oil, from poultry slaughterhouse, fish waste and grape seed. The characteristics of performance and internal egg quality were measured every 21 days for a total period of 84 days. Data were subjected to analysis of variance and the means were compared by Tukey’s test. There was no effect of treatments on the production performance of birds, except for feed intake, which was higher for birds fed grape seed oil in the diet. Lipid sources evaluated had no influence on the internal egg quality. It can be concluded that the lipid sources evaluated here in can be used as alternative energy in feed for laying quails, without affecting the performance and internal egg quality.
Highlights
Animal origin products have great importance in the human diet and health. Products, such as milk, meat and eggs have been the focus of much research aimed at identifying nutrients or agents that can promote healthy nutrition and, human health
Animal Sciences obtained are taken into account in these researches, which may affect both animal production costs and the gain in human health
Japanese quails (n = 160; Coturnix coturnix japonica), with 16 weeks of age were housed in galvanized wire cages with trough feeder and nipple drinker in conventional shed with galvanized wire mesh and curtains
Summary
Animal origin products have great importance in the human diet and health. products, such as milk, meat and eggs have been the focus of much research aimed at identifying nutrients or agents that can promote healthy nutrition and, human health.the use of certain ingredients in the diet of farm animals has attracted attention in research, in order to evaluate positive and negative points of their use. This study evaluated the addition of lipid sources to the diet of egg-laying Japanese quails in relation to production performance and internal egg quality.
