Description

An automatic breastfeeding machine dedicated to lactating puppies

technical field

The utility model relates to the technical field of animal husbandry and breeding equipment, in particular to an automatic breast-feeding machine for young rabbits in the lactation period.

Background technique

At present, in domestic rabbit breeding, the pups before weaning are all breast-fed by the female rabbit, and the lactation period is about 30 days. Most of the female rabbits have 8 teats, and generally can bring 4-8 pups alive. Taking the most intensive breeding mode as an example, the theoretical limit of each female rabbit can contribute 64 weaned rabbits per year. Among them, there are 4 difficulties:

1. During breastfeeding, the young rabbits often starve to death due to insufficient supply of breast milk;

2. After the young rabbits are 20 days old, the nutrition of the female rabbits shows a negative growth, and they lose weight rapidly, which affects the astern milk of this litter and the fetal development of the next litter;

3. The number of pups breastfed by the mother rabbit can only be controlled within 8 due to the number of nipples of the mother rabbit; the prolific pups of each female rabbit can only be eliminated;

4. The temperature and humidity in the production box are mainly maintained by bedding and bedding, and often freeze to death or trample to death.

At present, the production efficiency of my country's rabbit industry is still low, resulting in the cost of net rabbit meat far exceeding broiler chicken and lean pork. In the chicken industry, the artificial incubation of eggs is implemented, which greatly improves the production efficiency; the dairy cows are artificially fed with calves, which greatly reduces the cost.

To break the bottleneck in the development of the rabbit industry, it is an important topic that can greatly increase the productivity of the female rabbit and reduce the cost of feeding after the baby rabbit is born.

There are three major problems that need to be solved for the artificial feeding of puppies:

1. Source of nutrition. Developing the use of reconstituted milk in the early stage of lactation, liquid milk substitute feed in the later stage, and transition to full-priced pellet feed before weaning can speed up the growth and development of lactation and avoid growth retardation caused by weaning.

2. Environmental control. The breeding box fully meets the needs of pups of different ages. The breeding box is set in a special breeding room, equipped with automatic control systems for temperature, humidity, air quality, harmful gases, light, noise, etc. and a sterilization and disinfection system to create the most suitable nest environment for the growth of young rabbits. There is no need to use bedding and wool in the breeding box, which is clean and hygienic.

3. The automatic breastfeeding machine for puppies is the technical solution to be provided by the utility model.

The automatic lactation machine not only saves the breeding site, but also facilitates manual management. It is suitable for the intensive breeding management mode of all in and all out in the production of rabbits.

4. Rabbits and female rabbits are kept in separate cages, which prevents the possibility of the germs and viruses carried by the mother rabbits from spreading infection to the pups; prevents the female rabbit from jumping in and out of the pups' nest during breastfeeding, trampling or biting the pups The damage caused; after the pups and female rabbits are separated, it is also prevented that there are always young rabbits chasing the female rabbit to eat milk, which affects the occurrence of the female rabbit's rest.

5. Due to the configuration of special milk powder for puppies and the application of automatic breastfeeding machine, it can not only ensure the quality and temperature of milk, but also ensure sufficient milk supply, which makes up for the problem of insufficient milk in female rabbits and accelerates the growth of puppies The speed, the pups are in good shape, the weight gain is fast, and the weaning is early. The method of artificial feeding, especially for frail and underweight pups, can be managed separately, and the number of feedings can also be increased to ensure that the frail pups are fed, fed, and grow up healthily. It completely avoids the natural competition of the pups when the mother rabbit is feeding, and the weak pups will not be able to eat milk or be full of milk, resulting in weaker physique or even death. In the production example, an average female rabbit breastfeeds 8 young rabbits, and some litters of young rabbits died 4, leaving 4 young rabbits.

6. Artificial formula milk powder can be prepared according to the age, growth status and needs of pups, which is convenient and flexible. With milk as the base milk, the production cost is relatively low.

7. After the newborn rabbits eat the mother's colostrum at the age of 3 days, they leave the female rabbit. The female rabbit can return to milk and go into estrus again, and can be bred again. In this way, a female rabbit can be equipped with 11 litters a year, and contribute 122 weaned pups annually, which increases the number of viviparous births of the female rabbit. The nutrition that the mother rabbit used to suckle the pups is all supplied to the embryonic development of the pregnant rabbit, which is not only conducive to the recovery of the mother rabbit's physique, but also improves the weight and physique of the newborn rabbits, and improves the annual output of the mother rabbit. Aberdeen quantity.

8. The automatic breastfeeding machine is made of stainless steel, with accurate positioning, stable and flexible operation, low accident rate, and easy cleaning and sterilization.
