“…Thus, the egg is an important component in human diet due to protein input, containing (Grela, Ognik, Czech, & Matras, 2014). According to Bologa, Pop, and Albu (2013), many studies show that the chemical composition, biological value and physical and chemical properties of eggs are results of the effects of numerous factors, including breed, rearing condition, storage and culinary process of eggs in addition to animal nutrition.…”

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.Keywords: poultry slaughterhouse, soybean oil, fish waste, grape seed.Fontes lipídicas nas dietas para codornas japonesas em postura: desempenho e qualidade do ovo RESUMO. O objetivo deste trabalho foi avaliar a utilização de fontes lipídicas de origem animal e vegetal nas rações para codornas japonesas (Coturnix coturnix japonica), em relação ao desempenho zootécnico e à qualidade interna do ovo. Foram utilizadas 160 codornas japonesas, distribuídas em delineamento inteiramente casualizado, com quatro tratamentos e oito repetições por tratamento, com cinco aves por repetição. As fontes lipídicas avaliadas foram: óleo de soja, de abatedouro avícola, de resíduo de peixe e de semente de uva. As características de desempenho e qualidade interna dos ovos foram mensurados a cada 21 dias, em um período total de 84 dias. Os dados obtidos foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey. Não houve efeito dos tratamentos sobre o desempenho produtivo das aves, exceto para o consumo de ração, que foi maior para aves alimentadas com óleo de semente de uva nas rações. As fontes energéticas avaliadas não influenciaram a qualidade interna dos ovos. Diante disso, conclui-se que as fontes lipídicas avaliadas neste estudo podem ser utilizadas como ingredientes energéticos nas rações para codornas em postura, sem afetar o desempenho e a qualidade interna dos ovos.Palavras-chave: abatedouro avícola, óleo de soja, resíduo de peixe, semente de uva.

“…Recent studies have underlined its effectiveness on sheep (21,29), turkeys (19), laying hens (12), broiler chickens (8), and finally, pigs (14,15,22), where low alfalfa protein concentrate (APC) supplementation in the 2% -3% range caused higher weight gains and better feed conversion. Some research reports emphasise the effect of this preparation on the quality of animal product such as milk (5) and eggs (12), and on blood metabolic profile in humans (23,27). According to Davys et al (7), this supplement may also be used as a food additive for humans.…”

The aim of the study was to analyse the effect of the feed additive alfalfa protein concentrate (APC), on pig health. The trial involved 40 crossbred gilts and 40 crossbred castrates (Polish Landrace × Polish Large White) × Duroc of 29.0 ± 0.5 kg initial body weight. Allocation of experimental animals was into four treatment groups: the control group (C) was fed standard mixtures, without APC addition; group E-15 was fed a basal diet supplemented with 1.5% APC; and groups E-30 and E-30P were fed diets with 3.0% APC inclusion. There were two feeding systems. In the first system, animals of groups C, E-15, and E-30 were fed continuously with suitable mixtures. The second feeding system was used in group E-30P where animals received the experimental or control mixture alternating at two-week intervals. The addition of APC supplement to diets significantly increased (P ≤ 0.05) red blood cell indices, i.e. haematocrit (Ht), red blood cell count (RBC), and haemoglobin concentration (Hb) in growing and finishing periods. The analysis of enzyme activity demonstrated a markedly higher activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and especially alkaline phosphatase (ALP) in the blood plasma of pigs fed APC supplement. This increase may indicate a negative impact of APC on the animal's liver. A positive effect of dietary APC on blood lipid parameters was associated with a decreased level of total cholesterol and reduced low-density lipoprotein fraction. Analysis of the haematological and biochemical blood indices demonstrated that APC additive may affect animal health.
