Problems solved by technology

People try to replace exogenous hormone feed additives by stimulating the secretion of endogenous hormones to reduce the harm to the human body through the food chain, but they are still inferior to exogenous hormones in terms of the growth effect of animals

Embodiment 1

[0016] pig feed additive

[0017] 1 Experimental group

[0018] Select 90 piglets of three-way hybrid piglets with a weight of about 10 kg, and after 10 days of nursery transition, they are randomly divided into 9 groups, 10 pigs in each group, of which 3 groups are pine leaf extract test groups, named as the first group (The content of pine leaf extract is 250mg / kg), the second group (the content of pine leaf extract is 300mg / kg), the third group (the content of pine leaf extract is 400mg / kg); 4 groups are cysteamine test groups , respectively named the fourth group (cysteamine content of 75mg / kg), the fifth group (cysteamine content of 100mg / kg), the sixth group (cysteamine content of 400mg / kg), the seventh group ( The content of cysteamine was 800mg / kg), and two blank groups were set up, a total of 20 pigs were fed normally without adding pine leaf extract or cysteamine.

Embodiment 2

[0024] The 500-day-old laying hens have passed the peak of laying eggs and are ready to be eliminated. Take 375g of pine leaf extract, 375g of cysteamine and 800g of starch and fully mix to obtain a feed additive. The feed additive and the premix are dosed in a mass ratio of 1.5:1000. The egg production rate at 500 days of age was significantly improved, and the egg production rate was maintained at 81%. At 600 days of age, it was maintained at 75%. The average egg weight was 69 grams per egg. group compared with an increase of 18.9%.

[0025] The feed additive of the present invention can completely replace exogenous hormone additives on the premise of no harm to animals and human bodies, and the effect is obvious; by adding the feed additive equivalent to 0.2% of the feed weight in the feed, the feed additive can be added without increasing the amount of feed. On the premise that the average weight of each pig can increase by 50-300 grams per day; the weight gain of broile...

Abstract

The invention provides a feed additive for a pine needle extract. The feed additive is characterized by comprising the following components in parts by weight: 12.5-20 parts of pine needle extract and 5-20 parts of cysteamine. The feed additive also contains a small peptide preparation and a diluent, and the total weight of the small peptide preparation and the diluent is equivalent to 1-1.5 times of the total weight of pine needle extract and cysteamine. The pine needle extract is obtained by extracting effective components from pine needles by adopting an advanced sporoderm-breaking technique and an advanced extraction technology; as a health product for people, the pine needle extract is used for medicine, is widely accepted and developed and utilized extensively, can improve the immunity and increase appetite, and contains alkaloid, saponin, polysaccharide and multiple enzymes and coenzymes; various active components comprehensively act on a multi-layer regulation hormone axis of a neuroendocrine system, promote secretion of'endogenous hormones' together, and exert stable and durable growth-promoting effects.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a feed additive. Background technique [0002] Feed additives refer to the addition of a small or trace amount of nutritive or non-nutritive substances to feed in order to improve feed utilization, ensure or improve feed quality, meet the nutritional needs of animals, promote animal growth, and ensure the health of animals. Among them, feed additives can be divided into pharmaceutical additives and mineral additives. In the 1980s and 1990s, in order to improve the level and efficiency of farming, the farming industry of various countries in the world successively used additives such as exogenous hormones or psychotropic drugs in feed and drinking water. The hazards also emerged. [0003] Among the feed additives approved for use in my country, there are no varieties with high efficiency, low toxicity and no residue. It is of great significance to find feed additives that can...
