Description

Technical Field

[0001] The present application relates to the technical field of sow feed production, and in particular to a sow feed added with puffed rice and a production method thereof. Background Art

[0002] Feed is a general term for food for all animals raised by humans. In a narrower sense, feed refers primarily to food for animals raised in agriculture or animal husbandry. Feed includes over ten types of feed ingredients, including soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils and fats, meat and bone meal, grains, and feed additives.

[0003] Feeding standards, based on experience accumulated from livestock production practices and combined with energy metabolism and feeding experiments, scientifically define the daily amounts of energy and various nutrients that should be provided to livestock of varying species, gender, age, physiological state, production objectives, and levels. These prescribed amounts for livestock are called feed standards or nutritional requirements. The nutrient requirements specified in these standards are reflected through the consumption of various feeds. Therefore, in practical feeding practices, it is necessary to calculate the proportions of various feeds based on their characteristics, sources, prices, and nutrient content—in other words, to formulate a balanced, complete ration. Therefore, feed standards tabulate the nutrient requirements of livestock and poultry. For ease of use, a table of livestock feed ingredients and nutritional values ​​is included with the livestock feeding standards.

[0004] At present, the feed ingredients of sows are single, which cannot effectively improve the sow's body immunity, thereby affecting the body immunity of piglets. Therefore, it is necessary to produce a sow feed with added puffed rice. Summary of the Invention
