Comparison of Purified and Practical Diets for Reproduction in Japanese Quail ,

NUMEROUS experiments with laying hens conducted at this laboratory over the past several years have demonstrated that purified diets did not support reproductive performance equal to that obtained with practical diets. Both types of diets were formulated to contain adequate quantities of all known essential nutrients. Menge (1967) observed that rate of egg production, egg weight and hatchability of fertile eggs were significantly lower for hens fed a casein-gelatin-glucose diet compared with a corn-soybean diet. Substitution of isolated soy protein for casein and gelatin in the purified diet improved egg weight and hatchability but not rate of egg production. Young (1969) also noted that hens fed purified diets laid smaller eggs than hens fed a practical diet.The Japanese quail (Coturnix coturnix japonica) was selected to further investigate this problem. Wilson et al. (1961) described characteristics which make the Japanese quail a useful animal for research. Quail also eat less…

Effect of Gold Thioglucose on Survival, Feed Consumption and Body Weight of Broilers

INTRODUCTIONWAXLER and Brecher (1950) reported that about one-third of the stock albino mice that survived a single LD50 dose of gold thioglucose (GTG) developed varying degrees of hyperphagia and obesity. Marshall et al. (1955) found that the GTG induced obesity in mice was associated with lesions in the ventromedial nuclei in the hypothalamus. Liebelt and Perry (1957) reported that GTG produced different degrees of hypothalamic damage and obesity in two genetically independent inbred strains of mice.At the time the present study was initiated, there were no reports concerning the effect of GTG on fowl. Recently, Carpenter et al. (1969) reported that feed consumption, body weight and reproduction of Japanese quail were not affected by GTG treatment. Carpenter et al. (1969) did not find any evidence of destruction in either the hypothalamus or amygdala in GTG treated quail.The objectives of the present study were: (1) to determine the…

Effect of Wave Length of Light on Growth and Reproduction in Japanese Quail (Coturnix coturnix japonica)

LITERATURE on the effect of wave length (visible spectrum) on growth and reproduction in the fowl is limited and contradictory. Benoit and Ott (1944) found that gonadal development in the duck responded chiefly to the red wave lengths. Scott and Payne (1937) reported that subjecting immature turkeys to white light or the long wave lengths of red induced sexual maturity months in advance of the breeding season. In contrast to the above results, age at sexual maturity in the chicken is hastened by short wave lengths (blue and green), according to reports by Lauber (1965), Harrison et al. (1966), and McGinnis (1967). Donovan et al. (1965) reported an increase in production of gonadotropins by chickens receiving blue light.The purpose of this study was to determine the effect of different wave lengths of visible light, of known filtering characteristics, on growth and reproduction in the Japanese quail (Coturnix coturnix japonica)…

Selenium Deficiency and Impaired Reproduction in Japanese Quail

SummaryImpaired reproduction was observed in Japanese quail fed a diet low in both selenium and vitamin E from 1 day of age to maturity. Oviposition rate and fertility were not affected by the deficiency but hatchability of fertile eggs was markedly reduced and viability of both the adult females and the newly hatched chicks were reduced. Dietary supplementation with either selenium (1 ppm) or vitamin E (30 IU/kg) prevented the impaired reproduction but ethoxyquin (0.3%) was only partially effective.

Effect of Vitamin A on Growth, Egg Production and Reproduction of Japanese Quail

THE Japanese quail (Coturnix coturnix japonica) continues to receive increasing emphasis as a research animal since it grows rapidly, matures at an early age, and is a prolific egg producer. Although the Japanese quail has been advocated for many areas of avian research (Shellenberger and Newell, 1965), only limited information is available on its nutritional requirements.Fox and Harrison (1964) and Kienholtz et al. (1965) used these birds in a study of zinc deficiency and absorption. Nelson et al. (1964) have investigated calcium and phosphorus requirements of the adult bird, while Howes (1965) reported on the protein-energy interrelationships for the growing and adult Japanese quail. However, vitamin requirements of this species apparently have not been reported. This study was undertaken to determine the effect of vitamin A on growth, egg production, and reproduction of the Japanese quail.EXPERIMENTAL METHODSNewly hatched Japanese quail chicks from a stock colony maintained at …
