Poult Sci ; Services on Demand Article. This is possible due to the availability of industrial amino acids in the market. 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.

University Books Publishers; Temperature was recorded at 4: Temperature and humidity inside the shed were controlled with maximum and minimum thermometers, wet and dry bulbs, and according with the quail behaviour. The ideal protein concept implies feeding the best ratios between lysine and other amino acids, thus reducing the crude protein content of the diet.

Review of the nutrition of Japanese Quail. 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. A linear increase occurred in the laying phase for feed intake and weight gain of the birds.

Rev Colomb Cienc Pecu ; Total dietary protein and amino acids such as cystine, methionine, arginine, isoleucine, leucine, valine, lysine, serine, threonine, histidine, phenylalanine, tyrosine, and tryptophan are associated to feather formation.

Coturnix japonicaideal protein, productive performance, sulfur amino acids.

The units had 24 hours a day of artificial light with the same light bulbs used for warmth until birds were 15 days old. On em 40 days, two birds that were within the average weight of each experimental unit were slaughtered.


The cages were set inside a shed. According to these authors, a ratio lower than 0.

In conclusion, the 0. One sixty-watt light bulb was placed in each cage to warm the birds until they reached 15 days of age.

Lysine, methionine and glycine requirements of Japanese quail to five weeks of age. 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.

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

Nutrient requirements of poultry. 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. 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.

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. Carrera 75 Of.

The best ratio for uniformity of quails was 0. High protein ingredients e.

Feed intake was weekly measured and the average intake of died birds was subtracted to calculate the real consumption per experimental unit. Evaluated parameters Feed intake was weekly measured and the average intake of died birds was subtracted to calculate the real consumption per experimental unit.

A quadratic effect was observed for feed conversion and uniformity at 40 days of age, and percentage of feathers did not vary. 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 copombia and synthesis of feather proteins is as important as the need for body protein synthesis. Conflicts of interest The authors declare they have no conflicts of interest with regard to the work presented in this report.


The authors declare they colombla no conflicts of interest with regard to the work presented in this report. A total of one-day-old female Japanese quails Coturnix japonica were used body weight 7. Quail farming is very important for providing jobs and producing high quality protein at a low cost.

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.

How to cite this article. A basal diet formulated to meet all nutrient requirements was added with graded levels coturniculrura DL-methionine replacing glutamic acid. Low ratios were related to low weight of the animals, increased feed ingestion, and greater weight gain during the production phase. Mortality was daily recorded to determine bird viability in the growing and laying phases.

Most research has focused on the nutritional requirements of quails during the laying phase and there is little information about requirements during the growing phase.

Birds were dry-plucked and feathers were weighed for feathering calculations. When quails reached 40 days they had their beaks trimmed before moving them to egg laying cages.

The stocking density per experimental unit was
