Description

Technical Field

[0001] This utility model relates to the field of livestock feeding technology, and in particular to an automatic piglet feeding system. Background Technology

[0002] Piglets, due to incomplete physiological development, generally suffer from weak thermoregulation, an underdeveloped digestive system, and low passive immunity, leading to a high early mortality rate. The sow's milk production and nutrient concentration decrease significantly after three weeks of lactation, failing to meet the piglets' growing energy and nutrient needs. Therefore, external nutritional supplementation is essential to fill this gap, which is crucial for ensuring piglets' health and promoting uniform growth.

[0003] In current pig farming practices, nutritional supplementation for piglets (especially weak piglets) mainly relies on two methods: first, early feeding through feed troughs to encourage feeding; and second, artificial feeding for weak piglets that cannot compete for effective teats. Artificial feeding typically uses tools such as bottles and feeding cups, relying on manual labor for preparing, dispensing, and feeding the piglets with milk products or milk replacers. In large-scale pig farms, this process has become a routine but arduous management task.

[0004] However, the aforementioned manual feeding methods have significant drawbacks: firstly, they are highly dependent on manual labor, inefficient, and labor-intensive, making it difficult to achieve continuous and timely feeding; secondly, the amount, temperature, and concentration of milk depend on manual control, resulting in significant fluctuations that affect the digestion, absorption, and health of piglets. Therefore, developing an automated piglet feeding system that can achieve precise, efficient, and low-manual dependence has become an urgent technical problem to be solved in the livestock industry.

Under the action of the circulation pump 3, the prepared milk is delivered to the feeding bowls 6 in each farrowing crate through the circulation system outlet pipe 4 and the circulation pipe 5 for the piglets to eat. The milk returned by circulation enters the balancing collection pipe 2 through the circulation system inlet pipe 7.

The entire circulation pipeline 5 is cleaned by the circulation pump 3. After cleaning, the outer solenoid valve on the return pipe 11 is opened and the inner solenoid valve is closed, so that the cleaning liquid is discharged from the end of the return pipe 11.
