Reproduction in the Laboratory of Ornithology of Veterinary School of Ceara They were reared in experimental cages for Sixty Japanese quails ( Coturnix japonica) for meat and egg production On hatchability, egg weight loss, hatching time, and embryonic mortality. Quail eggs at tropical temperatures (28 ± 1✬) The objective of this research was to verify the effects of storing Japanese There are few studies about incubation techniques for Japanese quails. Comparing to Gallus gallus incubation literature, Some researchers have reported aĭecline in hatchability by as much as 5% per day after 7 days of storage (MayesĪnd Takeballi 1984). Increases the probability of failure to hatch (Whitehead et al 1985 Yoo and Proportion of embryonic mortality during storage and incubation and thereby It is reported that the increase in the number of storage days elevates the Too high water loss influences embryo development (Rahn and Ar 1974), and,Ĭonsequently, egg hatchability (Meir et al 1984). Hatching egg quality (Samli et al 2005 Scott and Silversides 2000). Is influenced by temperature and relative humidity during long-term storageĬonditions and has generally been reported to be detrimental to table and The storage promotes water loss from the egg through evaporation at a rate that Such practice demands electricity use and can To store eggs at low temperatures in tropicalĬountries such as Brazil, it is necessary the use of coolers in order to reduce Temperatures between physiological zero and normal incubation temperature ofģ7.5✬ (Fasenko et al 2001). To prevent abnormal growth of the embryo that could occur if eggs were held at The objective of storing eggs at temperatures well below physiological zero is Storage period, eggs must be stored at low temperatures. To avoid the embryonic development during In order to obtain a sufficient number of eggs to fill incubators, eggs are usuallyĪccumulated in storage over a period from 1 day up to 3 weeks before their To maintenance and improvement of quail egg production. Have been reared for both egg and meat production all over the country, mainlyīy small and medium size poultry producers. Quail production is an important poultry business in Brazil. Key words: egg weight loss, embryo mortality, hatchability, hatch time, hatch weight Rates of egg mass loss during incubation and the hatching time. It was also observed that the storage length influenced the Rate of unhatched eggs, mainly because of pre-incubation mortality or embryoĮarly embryo death. After one week of storage there was an increasing The storage of quail eggs at tropical temperatures seems to be suitable up to 6ĭays when hatchability is 70%. Unhatched eggs were opened for embryonic mortality classification. The eggs were stored at tropical temperature (28 ± 1✬Īnd 60% of RH) and submitted to different periods of storage, from 0 day untilġ4 days, forming 15 experimental groups. Thirty eggs were selected per day, duringġ5 days consecutively. In hatchability, egg weight loss, hatching time, and embryo mortality. Verify the effect of storage of Japanese quail eggs at tropical temperatures (28 ± 1✬) * Laboratory of Ornithology of Veterinary School of Ceara State University, Abstract Incubation of Japanese quail eggs stored at tropical temperatures J M Romao, T G V Moraes, E E Silva*, R S C Teixeira* and W M Cardoso* Department of Agriculture Food and Nutritional Science, University of Alberta, Canada Therefore, select a quail egg incubation temperature with accurate controls to keep the conditions at optimal levels.Incubation of Japanese quail eggs stored at tropical temperatures Livestock Research for Rural Development 22 (1) 2010 Finally, you need to maintain the humidity, temperature, and airflow inside the incubator at the required levels for efficient egg hatching. Select a machine that is easy to clean to maintain the required hygiene standards for egg hatching. Also, consider the ease of cleaning when settling for an incubator. Choose a quail egg incubation temperature within your budget with features fitting your needs.
The amount of money you are willing to spend on an egg incubator is another major consideration when purchasing one. It is essential to settle for a machine that fits the number of chicks you want to hatch. The capacity of the equipment determines the number and the type of eggs you can hatch. Before selecting egg hatching equipment, it is important to consider its egg capacity. These factors include capacity, cost, ease of cleaning, and accuracy of control. When selecting a quail egg incubation temperature for your farm, there are various factors to consider.
