There is a wonderful way to prolific female rabbits.
Prolific female rabbits is an effective way to improve feeding efficiency. So, how to give birth to female rabbits? Relevant studies have shown that the mating time of female rabbits is the key to determine the sex of future offspring. Experience shows that the male rabbits who have mated on the previous day mated with the female rabbits on the second day of oestrus, and most of them gave birth to female rabbits; if the male rabbits who were not mated in the third day mated with the female rabbits on the third day of estrus, the majority of male rabbits were born. The experiment showed that using the former mating method, 68 rabbits survived after giving birth to 9 litters, of which 57 female rabbits were born.

Conditions and main technical requirements for co-rearing of young silkworms
First, the purpose of co-rearing young silkworms, as the saying goes, "raise half of the young silkworms", which fully illustrates the importance of raising young silkworms. The purpose of the co-rearing of young silkworms is to enhance the physique of young silkworms to ensure the safety of large silkworms and to achieve high quality and high yield of cocoons. The advantages of small silkworm co-rearing are as follows: (1) it is beneficial to realize scientific sericulture, adopt advanced sericulture technology and facilities, promote the neat development and strong physique of young silkworms, provide guarantee for large silkworm rearing, and lay the foundation for high and stable cocoon production. (2) it is beneficial to disinfection and disease prevention. Overcome the resistance of young silkworms to adverse environment
