Methods for Pond Culture of Tubifex Worms and Key Points of Breeding Technology
For breeding premium aquatic products, feed is an important material foundation and restrictive factor, as it determines the success or failure of the cultured species and the level of economic benefit. Tubifex worms reproduce quickly and have high nutritional value (dry matter contains 62% crude protein, total essential amino acids reach 35%, nitrogen recovery rate reaches

Technical Methods for Inducing Estrus in Meat Dog Breeding
The estrous cycle of adult female dogs is irregular. Affected by many factors such as season, environment, feed structure, and physical condition, female dogs generally produce one and a half to two litters per year. Mastering artificial estrus induction techniques can enable most female dogs to produce two to two and a half litters per year, and four to five litters of pups in two years.

What are the prevention methods for abomasal displacement in dairy cows?
Under normal circumstances, the abomasum of a dairy cow is located on the right side of the abdominal cavity, with the left side adjacent to the rumen. However, due to certain internal or external causes, the normal position of the abomasum changes abruptly, either lying below the rumen or shifting to the left side of the rumen, all of which can cause the dairy cow to lose its appetite entirely.
