No effects of the assessed ratios were colomboa on the other variables. One glass pressure drinker was installed per cage. Rev Colomb Cienc Pecu ; 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.

Light was provided 16 hours a day during the experimental period. The experimental units were 50 x 34 rn galvanized wire cages in a ladder arrangement, equipped with gutter feeders in the front section and corresponding nipple drinkers.

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.

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. This was also achieved by hanging curtains on the laterals of the shed. Body fat and protein deposits were calculated by slaughtering an additional group of 50 one-day-old quail. A basal diet formulated to meet all nutrient requirements was added with graded levels of DL-methionine replacing glutamic acid.

Effect of enzyme supplementation on the metabolizable energy contento of solventextracted rapeseed and sunflower seed meals for chicken, guinea fowl and quail.

Temperature and humidity inside the shed were daily recorded. July 18, ; accepted: Temperature and humidity inside the shed were controlled with maximum and minimum thermometers, wet and dry bulbs, and according with the quail behaviour.


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

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

On reaching 40 days, two birds that were within the average weight of each experimental unit were slaughtered. Nevertheless, this practice increases production costs, deviate amino acids for functions not related to growth, worsens environmental conditions, and increases pollution.

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. Br Poult Sci ; The experimental unit consisted of 20 birds per cage, with 10 replicates.

The units had 24 hours a day of artificial light with the same light bulbs used for warmth until birds were 15 days old. High protein ingredients e.

When quails reached 40 days they had their beaks trimmed before moving them to egg laying cages. 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.

Official methods of analysis, 17nd ed. This is possible due to the availability of industrial amino acids in the market. A quadratic effect was observed for feed conversion and uniformity at 40 days of age, and percentage of feathers did not vary.


The best ratio for uniformity of quails was 0. Quails are characterized by early sexual maturity 40 daysdemanding feeding programs that maximize growth by combining body development with sexual maturity, thus allowing uniformity of breeding stock and productivity Pinto et al.

Methionine supply during the growth phase can influence the weight at sexual maturity and egg size. Quail farming is very important for providing jobs and producing high quality protein at a low cost.

They were made of galvanized wire and coturnicultuga and managed under a raffia curtain coturniculgura the first 15 days of the birds’ life to keep the place warm.

Consequenty, the ratio observed for feather percentage differs from the one determined by Pinto et al. How to cite this article. Feed intake was weekly measured and the average intake of died birds was subtracted to calculate the real consumption per experimental unit.

A deficiency in crude protein could result in deficient feathering of birds.

Conflicts of interest The authors declare they have no conflicts of interest with regard to the work presented in this report. Feed conversion per dozen eggs was worst for quails fed the lowest ratios 0. Light supply was controlled with a timer, eh the cooturnicultura to be turned on and off at night and early morning, in accordance with common procedures in commercial poultry farms.

Quails were guided to the water right after being housed.
