\"The<\/a>A study carried out at the Department of Animal Science of Universidade Federal do Cear\u00e1 (UFC) evaluated different feeding programs for European meat-type breeder quail and found evidence that small restrictions in feed supply can reduce feed intake and bird mortality without affecting egg production, egg quality, or hatchability rates. The study was developed in partnership with the institution\u2019s meat quail breeding group and involved undergraduate and graduate students as well as faculty specialized in poultry nutrition, management, and genetics. The article Feeding programs for the grower phase of two strains of meat-type breeding quails<\/a> was published in the journal Ci\u00eancia Rural<\/em> (vol. 55, no. 8, 2025).<\/p>\n

According to researcher Fernanda de Ara\u00fajo, \u201cthe idea arose because the production sector had been reporting difficulties in controlling the body weight of meat quail breeders, which consume large amounts of feed and may become obese, reducing fertility, increasing mortality, and raising production costs,\u201d in addition to the lack of specific information for this category of birds, since \u201cmost previous studies focus on Japanese laying quail or broilers, and there were almost no data on European meat-type breeder quail.\u201d<\/p>\n

The experiment used 480 quail distributed into three feeding programs between 14 and 42 days of age: ad libitum<\/em> feeding (as much as desired), controlled feeding per bird per day, and a version of controlled feeding with a 10% restriction. The birds were monitored from the initial phase up to 51 weeks of age, evaluating feed intake, weight gain, sexual maturity, egg production and quality, and incubation parameters. According to the researcher, \u201cour results show that a mild restriction of only 10% during growth reduces feed intake, weight gain, and final body weight, and delays the age at first egg by about four days, without compromising any reproductive parameter.\u201d<\/p>\n

The data confirm these findings: birds in the restricted group consumed less feed and had lower body weight both at 42 days and at the end of the laying cycle, in addition to showing lower mortality, whereas birds fed ad libitum<\/em> had the highest mortality during the productive phase. \u201cReducing mortality without harming fertility, hatchability, and egg quality is extremely relevant for the sector,\u201d Fernanda comments. She emphasizes that controlling breeder body weight is essential to prevent obesity, which may impair ovulation and egg development.<\/p>\n

Despite differences in feed intake and body weight, there were no losses in egg production, egg mass, internal and external egg quality, or hatchability rates among the evaluated programs. \u201cThis means we can adjust feeding programs during the growth phase to reduce costs and improve bird welfare without losing reproductive efficiency \u2014 something very valuable for commercial farms,\u201d she explains.<\/p>\n

In practice, the results may help farms design more efficient feeding programs for breeder quail. Scientist Fernanda summarizes: \u201cif the farm\u2019s goal is management simplicity, ad libitum<\/em> or controlled feeding works well; but if the objective is to reduce feed intake and mortality, mild restriction is a safe alternative, provided it is properly monitored.\u201d She reinforces that any change should be applied only during the growth phase, since after 42 days all birds received laying feed ad libitum<\/em>.<\/p>\n

The study stands out for monitoring quail throughout the entire production cycle and for simultaneously evaluating performance, maturity, production, egg quality, and incubation variables \u2014 aspects still little explored in European meat-type quail. \u201cOur work helps fill an information gap and has the potential to guide management manuals and on-farm decision-making,\u201d the author states.<\/p>\n
