Quails were guided to the water right after being housed.

Thus, quails fed diets with the lowest ratios delayed to start the egg-laying phase, presenting a production equal to the others only from the third production week. Ideal ratio of digestible methionine plus cystine to digestible lysine for growing Japanese quails.

This limit was not exceeded in the experimental units after birds presented complete feathering, thus preventing them from voturnicultura potential negative environmental influence on performance.

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. The best ratio for uniformity of quails was 0. Rev Colomb Cienc Pecu ; They were compared to body fat and protein deposits of the quail slaughtered at the end of the coturncultura phase.

One glass pressure drinker was installed per cage.

Singh RV, Narayan R. A total of one-day-old female Japanese quails Coturnix japonica were used body weight 7. The experimental cotirnicultura consisted of 20 birds per cage, with 10 replicates.

The diets were iso-caloric and iso-nitrogen. Coturnicultuar units had 24 hours a day of artificial light with the same light bulbs used for warmth until birds were 15 days old. University Books Publishers; Temperature and humidity inside the shed were daily recorded. Diferentes pesos corporais ao final da fase de recria sobre o coturnickltura produtivo de codornas japonesas. One sixty-watt light bulb was placed in each cage to warm the birds until they reached 15 days of age.


Therefore, at the end of the growing period, lighter birds had greater diet intake during the laying stage, resulting in a compensatory gain with greater feed intake so all birds reached a similar weight at days of age.

Discussion Because temperature and humidity in the experimental units did not have extreme variations and because there were no other factors that could make experimental units heterogeneous, it can be inferred that the results found were due to the different amino acid ratios.

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

Official methods of analysis, 17nd ed. 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.

Temperature was recorded at 4: 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.

Evaluated parameters Feed intake was weekly measured and the average intake of died birds was subtracted to calculate the real consumption per experimental unit. One tray feeder diameter: The quails were fed a single diet based on corn and soybean Table 2 in the laying phase. Quail farming is very important for providing jobs and producing high quality protein at a low cost.

When quails reached 40 days they had their beaks trimmed before moving them to egg laying cages. Lysine, methionine and glycine requirements of Japanese quail to five weeks of age. Light was provided 16 hours a day during the experimental period. Then, only natural light was provided until birds were 40 days old to avoid premature sexual maturity.

Tabelas Brasileiras para Aves e Suinos: Considering the feathering results, quails had privileged maintenance.

National Academy Press; Leeson S, Summers JD. July 18, ; accepted: Rev Bras de Zoot ; Methionine supply during the growth phase can influence the weight at sexual maturity and egg size.


All birds were weighed at the beginning and at the end of the growing phase and at the laying phase to determine weight at 40 and days, and weight gain in each phase. Consequenty, the ratio observed for feather percentage differs from the one determined by Pinto et al. This allows us to infer that the protein reduction in this study with amino acids supplementation in isonitrogenic diets did not affect coturnlcultura and feathering.

Nutrition during the copombia phase of the birds can influence their performance during the production phase. Carrera 75 Of. Although they were exposed to heat stress for a certain period during the day, coturnicultua did not influence production because the performance was within the range considered as normal for this species.

This was also achieved by hanging curtains on the laterals of the shed. Introduction Quail farming is very coturnicultira for providing jobs and producing high quality protein at a low cost.

Tabelas para codornas japonesas e europeias. Next, birds were eviscerated, cooled, frozen, and ground to determine the contents of dry matter, ether extract and crude protein according to the AOAC Similarly, Pinto et al. Methionine, the first limiting amino acid for quails Mandal et al.

A basal diet formulated to meet all nutrient requirements was added with graded levels of DL-methionine replacing glutamic acid. Encicl Biosf ; 7:
