Singh RV, Narayan R. This ratio is higher than 0. Tabelas para codornas japonesas e europeias.

[Studies on quail culture [Colombia]]. [Spanish] [1975]

Evaluated parameters Feed intake was weekly measured and the average intake of died birds was subtracted to calculate the real consumption per experimental unit. They were made of galvanized wire and covered and managed under a raffia curtain for the first 15 days of the birds’ life to keep the place warm.

In general, the birds were provided appropriate temperature and humidity in the experimental units according with the literature, records of maximum and minimum temperature and relative humidity Table 3 as well as the behavior of the animals.

The best ratio for uniformity of quails was 0. A deficiency in crude protein could result in deficient feathering coturnicultufa birds. Total dietary coombia and amino acids such as cystine, methionine, arginine, isoleucine, leucine, valine, lysine, serine, threonine, histidine, phenylalanine, tyrosine, and coturjicultura are associated to feather formation.

This diet was formulated to meet the nutritional requirements proposed by Rostagno et al. English pdf Article in xml format Article references How to cite this article Automatic translation Send this article by e-mail.

Ideal ratio of digestible methionine plus cystine to digestible lysine for growing Japanese quails

The ideal protein concept implies feeding the best ratios between lysine and other amino acids, thus reducing the crude protein content of the coturniccultura.


Laying phase from 41 to days of age Birds were moved to laying cages at 41 days of age keeping the same birds from each experimental unit together to evaluate growth and development during the laying phase. Considering the feathering results, quails had privileged maintenance. Conflicts of interest The authors declare they have no conflicts of interest with regard to the work presented in this report. Methionine supply during the growth phase can influence the coturnixultura at sexual maturity and egg size.

Nutrition during the growing phase of the birds can influence their performance during the production phase.

Universidade Estadual Paulista; For the calculation of body fat and protein deposits, the value found in the sample was compared with the average weight of the live animal in each experimental unit, according to Pinto et al. Tabelas Brasileiras para Aves e Suinos: Diferentes pesos corporais ao final da fase de recria sobre o desempenho produtivo de codornas japonesas.

Services on Demand Article. Although they were exposed to heat stress for a certain period during the day, this did not influence production because the performance was within the range considered as normal for this species.

Temperature and humidity inside the shed were controlled with maximum and minimum thermometers, wet and dry bulbs, and according with the quail behaviour.

The authors declare they have no conflicts of interest with regard colommbia the work presented in this report. High protein ingredients e. Since methionine is an important sulfur amino acid in the translation of messenger RNA, being the first amino acid incorporated in the N-terminal position of all proteins, methionine requirement for maintenance and synthesis of feather proteins is as important as the need for body protein synthesis.


Light was provided 16 hours a day during the experimental period. Feed conversion per dozen eggs was worst for quails fed the lowest ratios 0. In conclusion, the 0. Introduction Quail farming is very important for providing jobs and producing high quality protein at a low cost.

The stocking density per experimental unit was O fornecimento nutricional de metionina durante a fase de crescimento pode influenciar fatores como peso corporal para maturidade sexual e tamanho do ovo. The units had 24 hours a day of artificial light with the same light bulbs used for warmth until birds were 15 days old. No effects of the assessed ratios were observed on the other variables. Nutrient requirements of poultry.

One tray feeder diameter: Light supply was controlled with a timer, allowing the lights to be turned on and off at night and early morning, in accordance with common procedures in commercial poultry farms.

Carrera 75 Of.

The use of synthetic amino acids is an interesting alternative to minimize those problems Silva and Costa, Although a similar response was noted in this study, the best result for feathering was obtained using a lower ratio than that required for weight gain and feed conversion. All the intact eggs produced per replicate in the last three days of each week were weighed and total weight was divided by the number of eggs weighed. This allows us to infer that the protein reduction in this study with amino acids supplementation in isonitrogenic diets did not affect maintenance and feathering.

According to these authors, a ratio lower than 0.
