The aim of this study was to evaluate the effects of dietary vitamin E on reproductive and productive parameters in Japanese quails. A total number of 240 female and 80 male Japanese quail were divided into five treatments with four replications in a completely randomized design. Experimental diets were zero control, 30, 60, 120 and 240 mg kg-1 of vitamin E. Fertility and total hatch...

the purpose of the present study was to evaluate the impact of vitamin e and selenium (se) supplementation on the performance, egg quality and hatchability of eggs from japanese breeding quails. the experiment was conducted over a 60 day period using 135 quails in a completely randomized design (crd) with two levels of vitamin e and two levels of selenium (80 mg/kg of vitamin e+0.2 mg/kg organi...

The study was carried out to determine the effects of the parental age and egg weight of Japanese quail on the weight of one day old chick, fertility and hatchability of incubated eggs. Three hundred and sixty Japanese quail eggs were obtained from 22 and 36 weeks old quails. The eggs were weighed and grouped into 2 categories: Light (7.5-9.5g) and Heavy (9.6 – 12g). The weight of the chicks we...

The quail raising in Brazil has increased through the last years and the incubation procedures are important to maintenance and improvement of quail egg production. To obtain a sufficient number of eggs to fill an incubator, eggs are usually accumulated in storage over a period from 1 day up to 3 weeks before incubation. The objective of this research was to verify the effect of egg storage on ...

Submitted: Jan 2, 2013; Accepted: Feb 6, 2013; Published: Aug 18, 2013 Abstract: This study was undertaken to determine the effects of divergent selection and different positions of Japanese quail eggs in artificial incubation on hatchability, egg weight loss, chick weight. 300 Japanese quail (100 birds in each line) were used for egg collection. These lines have been selected for high (HW) and...

To determinate the effect of chromium-methionine level in diet on hatchability of Japanese quail in dry tropic weather under temperaturecontrolled in summer season, a completely randomized design experiment was conducted. Thousand two hundred eighty Japanese quail (960 females and 320 males), they were divided in 160 groups of eight (six females and two males), and were allocated in wire cages ...

This study was conducted to investigate the effect of egg size, age of hen and storage period of eggs before incubation on fertility, hatchability, embryo mortality and chick malformations in Japanese quail (Coturnix coturnix japonica). The study was carried out in quail farm located at Tanah Merah, Kelantan. Totally 1441 eggs of quail were set into the incubator by applying 9 treatments groups...

The Japanese quail has been utilized as a research species in establishing the genetic relationships that may also be present in other species. Divergent phenotypic selection for 4-wk BW was conducted for three generations in high (HW) and low (LW) lines. Within each line, 50 females and 25 males were selected among 600 birds, based on 4-wk BW. Mean BW at 4 wk of age in the base generation was ...

Various factors play important roles in influencing hatchability efficiency and growth performance during embryonic and post-hatch life, such as genetic, egg characteristics and incubation environment (Christensen, 1995; Nestor and Noble, 1995; Narushin and Romanov, 2002; Petek et al., 2003; Abiola et al., 2008). Light is one of the environmental factors that improves embryonic growth and hatch...

Yolk deposited by Japanese quail was abnormal for 24 hours after the oral administration of a single capsule containing 200 milligrams of bunker C oil. Both the structure and the staining properties of the yolk were affected. Fewer eggs were laid during the 4 days after dosing, compared to controls, and hatchability was drastically reduced. Hatchability returned to normal in 4 days. Three other...
