parent turtle culture

The female tortoise is more than 0.5 kg and the male turtle is more than 0.15 kg. The tortoise over 5 years old is suitable to be the parent. The ratio of female to male was 3 ∶ 1 and the density was 0. 6ind / m 2. Parent turtle feed with 40% crude protein and 20% fresh feed. The sexual maturity of turtles in South China is 5 summer years old, and the first turtles lay 1 litter of eggs per litter. 8-year-old female turtles lay an average of 3.2 eggs per litter, with an average of 5.5 eggs per litter, with an average of 16-20 eggs per year. 10-year-old female turtles lay more than 4.5 eggs a year, laying more than 30 eggs a year, with a maximum of 14 eggs per litter. The study shows that the older the female turtle is, the larger the individual is, the more eggs are laid, the weight of the egg is heavy, and the hatched turtle seedlings are larger. The parent female turtle should be more than 7 years old, the individual weight should be 0.5-0.7 kg, and the male tortoise should weigh more than 0.3 kg.
