Description

Technical Field

[0001] This invention relates to the field of feed additive technology, and in particular to a feed additive that reduces the content of behenic acid and erucic acid in animals. Background Technology

[0002] Behenic acid and erucic acid are two common fatty acids found in high amounts in some vegetable oils and animal fats. However, these two fatty acids can have adverse effects on animal health, requiring special attention during animal husbandry. Furthermore, behenic acid and erucic acid affect the flavor and quality of animal meat, thus impacting human health. Behenic acid is a long-chain saturated fatty acid, a type of saturated fatty acid that increases cholesterol levels. Intake increases cholesterol levels in the blood of both humans and animals, thereby increasing the risk of cardiovascular diseases. In addition, behenic acid can also affect the normal function of the immune and reproductive systems in animals.

[0003] Erucic acid is an unsaturated fatty acid containing double bonds. It is relatively unstable and easily oxidized to produce harmful substances. When animals ingest excessive amounts of erucic acid, they may experience problems such as stunted growth, weakened immunity, and decreased reproductive capacity. Furthermore, erucic acid can damage the liver and kidneys. Behenic acid and erucic acid can also affect the flavor of meat. Therefore, in animal husbandry, attention should be paid to diets that may increase the levels of behenic acid and erucic acid in animals, ensuring that the types and amounts of fatty acids in the animal's diet are beneficial to its health.

[0004] Excessive accumulation of behenic acid and erucic acid in animals can lead to health problems such as obesity, high blood pressure, and high cholesterol. Clearly, these two fatty acids can have adverse effects on animal health. Therefore, how to reduce the levels of behenic acid and erucic acid in animals through the use of specific feed additives is a pressing technical challenge that needs to be addressed. Summary of the Invention

[0039] Effect verification experiment:

[0040] Healthy chickens and pigs of the same age, raised under the same conditions, were divided into groups of an average of 20 birds per group. The feeding details for each group are as follows:

[0041] Experimental Group 1: The chicken feed additive prepared in Example 1 was added to the chicken basal diet at a dosage of 0.5%.

[0042] Experimental Group 2: The pig feed additive prepared in Example 2 was added to the basal diet of pigs at a dosage of 0.5%.

[0043] Control group 1: fed with a basal chicken diet;

[0045] The chickens used in this invention were purchased from an egg-laying chicken breeding base in Taoyuan County, Hunan Province. The basic chicken diet formula is corn-soybean meal type, formulated according to the nutritional requirements of laying hens in the Chinese "Chicken Feeding Standard (NY / T33—2004)". The composition and nutritional levels of the basic chicken diet are shown in Table 1:
