Description
This study was conducted to investigate the rate of raising, viability and growth rate of the Gifu Native Fowl. Results obtained are as follows.<br>(1) Rate of raising and viability<br>The average rate of raising during 20 weeks of age and viability after 20 weeks of age for male and female birds were approximately 92% and 90%, and 74% and 72%, respectively.<br>The viability of males hatched on February was higher than that of the birds hatched on March, May, June, September and December. On the other hand, females hatched on July were higher than that of birds hatched on January, April and August.<br>(2) Growth rate<br>Body weight of males or females is increased gradually till about 28 or 24 weeks of age. The mean values of body weight for males at 28 and 55 weeks of age were nearly 1, 140 and 1, 297 g, and 873 and 920 g for females at 24 and 55 weeks of age. No appreciable change was observed in the body weight after 55 weeks of age. However, summer season caused a slight decrease in the body weight for both sexes.
