Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and in particular to an SPF piglet feeding device. Background Technology

[0002] SPF (Specific Pathogen Free) piglets play a vital role in biomedical research and high-end livestock breeding. Their rearing process requires strict control of a sterile environment and meticulous nutritional management. Feeding with colostrum or milk replacer is crucial for ensuring piglet survival and immune development. However, existing feeding devices have several problems that limit the health and growth of SPF piglets.

[0003] First, the steam aerosol generated during open-top milk tray heating may carry Bacillus spp. from the environment, which can settle on the milk surface, further increasing the risk of contamination. Second, precise temperature control is lacking. Immunoglobulins (IgG) and lactoferrin in milk replacer are easily denatured and inactivated at high temperatures, but existing equipment relies on manual temperature measurement, resulting in large temperature fluctuations (±5℃) and nutrient degradation. Third, there is excessive reliance on manual intervention. Frequent manual intervention (such as holding piglets) can trigger stress responses in piglets, increasing cortisol levels and inhibiting their active sucking behavior. A single operator can only feed 15-20 piglets per hour, which cannot meet the production needs of large-scale SPF facilities.

[0004] In summary, existing feeding devices have significant shortcomings in terms of aseptic control, temperature regulation, and human dependence. There is an urgent need to develop a new SPF piglet feeding device to improve feeding efficiency and piglet health. Utility Model Content
