“…However, Dowarah & Sethi (13) observed that the growth performance was higher in Japanese quail during starter (1 to 3 week) fed on high protein and high energy (27% CP and 3000 Kcal ME/kg). Jordão Filho et al (3) observed that dietary requirement for protein gain was 30% higher for Japanese quails compared with the European, due to their being less efficient in the use of dietary protein to gain than European quails.…”

The aim of this study was to evaluate crude protein (CP) levels for European quails from one to 14, 14 to 28 and 28 to 42 days old. The experiment was carried out in a completely randomized experimental design, with five treatments and five replications. No significant effects of CP levels on weight gain and feed conversion from 1 to 14 days were observed, however quails fed 26% CP diets had lower feed intake. The CP levels from 14 to 28 days had significant effect on feed intake, weight gain and feed conversion. Maximum weight gain and minimum feed conversion were estimated for quails fed 24% CP. The CP levels had a significant effect on the traits studied in the final phase, highest weight gain and lowest feed conversion were estimated for quails fed 23% CP. No significant effects of CP levels on hot and cold carcass weights, breast weight, and thigh and drumstick weight were observed. The crude protein requirements for European quails from 1 to 14, 14 to 28 days and 28 to 42 days old are 26, 24 and 23%, respectively, if the requirements of the first limiting amino acids are met. Keywords: Amino acids, carcass yield, Coturnix coturnix, performance. ResumoO objetivo deste estudo foi avaliar níveis de proteína bruta (PB) para codornas europeias de um a 14, 14 a 28 e 28 a 42 dias de idade. O delineamento experimental foi inteiramente ao acaso, com cinco tratamentos e cinco repetições. Os níveis de PB não influenciaram o ganho de peso e a conversão alimentar das codornas de 1 a 14 dias de idade. Porém, a dieta contendo 26% PB resultou em menor consumo da dieta. Os níveis de PB utilizados no período de 14 aos 28 dias influenciaram o consumo da dieta, o ganho de peso e a conversão alimentar, sendo o melhor ganho de peso e conversão alimentar estimados com dietas contendo 24% PB. Houve efeito significativo dos níveis de PB estudados, sobre o ganho de peso e conversão alimentar no período final, com máximos desempenhos estimados para codornas alimentadas com dieta com 23% PB. Não houve efeito dos níveis de PB sobre o peso da carcaça quente e peso da carcaça resfriada, peso do peito e da coxa mais sobrecoxa. As exigências de PB estimadas para codornas europeias são 26, 24 e 23% para as fases de 1 a 14 dias, 2 Cienc. anim. bras., Goiânia, v.18, 1-12, e-28085, 2017Crude protein in diets of european quails 14 a 28 dias e 28 a 42 dias de idade, respectivamente, se forem atendidas as exigências dos primeiros aminoácidos limitantes.

“…Several studies with quails or broiler chickens have shown that performance is adversely affected with low dietary CP and investigated the main reasons for decreasing growth performance (Folorunso, Adesua, & Onibi, ; Malomo, Bolu, & Olutade, ). On the other hand, Dowarah and Sethi () concluded that dietary CP during starter (23%, 25% and 27%) and finisher (18%, 20% and 22%) phases had no influence on performance of Japanese quail. Low‐CP diet supplemented with synthetic amino acids supports quail performance and is an excellent strategy for mitigating ammonia pollution and reducing feeding cost (Alagawany, Abd El‐Hack, Laudadio, & Tufarelli, ).…”

This study was to investigate the effect of dietary protein levels and supplementation with two cold‐pressed oils on the performance, immunity and antioxidant indices of growing Japanese quails. A 3 × 4 factorial experiment, using 3 dietary crude protein (CP) levels (22%, 24% and 26%) and 4 supplemental herbal oils levels: control without additives, 250 mg marjoram (Mar), 250 mg thyme (Thy) and 125 mg Mar + 125 mg Thy per kg diet. A total of 720 unsexed, 7‐day‐old quail chicks were randomly distributed into twelve treatment groups (4 replicates per group of 15 chicks in each). The live body weight (LBW) on 42 days and body weight gain (BWG) from 7 to 42 days were significantly improved (p < 0.01 and 0.05) in chicks fed 24% or 26% CP compared with those of the 22% CP group. The groups fed diets supplemented with Mar or in combination with Thy oil exhibited significantly better LBW, BWG and feed conversion ratio (FCR) than the control at all periods except BWG from 21 to 42 days and FCR from 7 to 21 days were not significant. Feed intake was gradually decreased with increasing dietary CP level or adding herbal oils during the periods 21–42 and 7–42 days of age. Plasma triglycerides, cholesterol, total lipids and malondialdehyde were decreased by cold‐pressed oils supplementation, but the activity of reduced glutathione and superoxide dismutase was increased (p < 0.01) compared with the control. In conclusion, quails fed a diet containing 24% or 26% CP or diets supplemented with Mar or Thy oils or both exhibited improvement in the performance, lipid profile, immunity and antioxidant capacity without any detrimental impacts on the other studied parameters.

“…In fact, many domestic chickens are severely affected by natural heat stress due to location of tropical or subtropical regions [6,9]. Recently, nutritional strategies have been proposed that can be used to improve the tolerance of birds to heat stress, such as dietary reduction of protein [10,11] or energy and the introduction of dietary supplements [12,13]. With the focus on the animal health, more and morenatural and safe feed additives have become the primary choice for farms.…”

The present study was conducted to evaluate the effects of dietary supplementation of tea polyphenol （TP） on serum hormone, serum enzyme activity, antioxidant-related and immune-related gene expression of laying hens under heat stress. A total of 288 Chinese yellow chicken (186 days old) were randomly distributed among two treatments, each of which included 6 replicates of 24 hens. Dietary treatments were that the basal diet was supplemented with 200 mg / kg tea polyphenol. The study lasted for 7 weeks, including 1 week of adaptation and 6 weeks of the formal test. The content of high-density lipoprotein cholesterol (HDL-C) and total protein (TP) in serum significantly decreased by dietary supplementation with tea polyphenol. Dietary tea polyphenol supplementation improved serum superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) enzyme activity and decreased serum malondialdehyde (MDA) content in treatments compared to the control. However, supplementation of tea polyphenol did not affect the activity of serum catalase (CAT). The results indicated that long-term feeding of tea polyphenols help to increase the amount of hormones (FSH, E2) associated with reproduction in laying hens and thus improve egg production. It also improved the immune function of laying hens in high temperature environments. Adding tea polyphenols to the diet can significantly increase the serum IgG, IgM content of the laying hens and can upregulate the IgA content. Dietary supplementation of tea polyphenols in the laying hens significantly increased the expression of antioxidant enzyme-related genes (SOD, CAT and GPX1) in the liver. Moreover, the addition of tea polyphenols significantly increased the expression of immune-related genes (Interferon-γ (INF-γ), Interleukin 2 (IL-2) and Interleukin 4 (IL-4)) in the spleen. It is concluded that addition of tea polyphenols has a positive effect on antioxidant activity and immune function of laying hens.
