Problems solved by technology

The main reasons for this technical bias are: the growth-promoting effect of exogenous hormones is directly to the cell body through blood circulation, and it is not regulated by factors that deplete inhibitory factors; after exogenous hormone additives are banned, People simply replace exogenous hormones with endogenous hormones, ignoring the inhibitory effect of inhibitory factors on endogenous hormones, and ignoring the effect of enhancing the effect of endogenous hormones by depleting inhibitory factors

Embodiment 1

[0016] Embodiment 1 pig feed additive

[0017] 1. Single factor experiment

[0018] 1 experimental group

[0019] Select about 90 piglets of three-element crossbreed piglets with a weight of about 10 kilograms, and through 10 days of nursery transition, they are randomly divided into 9 groups with 10 pigs in each group, of which 3 groups are pollen extract test groups, respectively named as the first group ( Pollen extract content is 250mg / kg), the second group (pollen extract content is 300mg / kg), the third group (pollen extract content is 400mg / kg); 4 groups are cysteamine test groups, named respectively The fourth group (cysteamine content is 75mg / kg), the fifth group (cysteamine content is 100mg / kg), the sixth group (cysteamine content is 400mg / kg), the seventh group (cysteamine content 800 mg / kg), and two groups of blank groups were set up, a total of 20 pigs were fed normally without adding pollen extract or cysteamine. The experiment started on April 8, 2006 and ende...

Embodiment 2

[0029] Embodiment 2 fish feed additive

[0030] single factor experiment

[0031] 1 experimental group

[0032] 160 tilapias of about 50 grams were randomly divided into 8 groups: pollen extract test groups 1, 2 and 3, the contents of pollen extract were 300, 500 and 800 mg / kg respectively; cysteamine test groups 4 and 5 , 6 groups, cysteamine content were 100, 300, 500mg / kg; control group 2, no pollen extract or cysteamine added; 20 tails in each group. Each group was placed in a sterilized cement pool with a volume of about 1 cubic meter.

[0033] 2 Experimental steps

[0034] Fish farms use fish premixed feed from Shennong Feed Company to prepare bait according to the standard, and then add the pollen extract or cysteamine in the formula amount in the experimental group to the bait to make pellets to feed the fish.

[0035] 3 Experimental results

[0036] The experimental results are shown in Table 2.

Embodiment 3

[0041] Embodiment 3 chicken feed additive

[0042] single factor experiment

[0043] 1. Experimental grouping

[0044] A total of 480 hatchlings of Avian broiler chickens with normal development and health were selected for 4 days of adaptive brooding, and then randomly divided into 8 groups with 60 chicks in each group. Among them, 3 groups are pollen extract groups, and the contents of the pollen extracts in groups 1, 2, and 3 are 80 mg / kg, 150 mg / kg, and 300 mg / kg, respectively. The other three groups are cysteamine test groups, which are groups 4, 5, and 6, and the contents of cysteamine are 80 mg / kg, 100 mg / kg, and 400 mg / kg, respectively.

[0045] 2. Experimental steps

[0046]The broiler commercial full-price powder produced by Yunnan Shennong Feed Co., Ltd. was selected, and the pollen extract and cysteamine were mixed evenly with the mixer in the feed processing room of the farm after purchase. The wooden fence semi-open chicken house for the production of commerc...

Abstract

The invention relates to the field of livestock raising, in particular to a feed additive. The feed additive comprises the following components in parts by weight: 12.5-20 parts of pollen extracts and 5-20 parts of cysteamine. The feed additive can completely replace exogenous hormone additive on the premise that the feed additive is harmless to animals and human bodies, and has obvious effect; by adding the feed additive which accounts for 0.2% of the feed by weight to the feed, on the premise that the feed amount is not increased, the weight of each pig increases by 50-300g each day on average and the weight of each fish can increase by 15-20%, and the body color and shape of the fish are very close to those of wild fish, the weight of each broiler can increase by 15-20% and the broilerhas red crown and colorful feathers, and the laying rate of layer chicken can increase by 18-23% and the layer chicken has big eggs, thick eggshells and good eggshell shape.

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 psychoactive drugs in feed and drinking water, but the residues of such drug additives are harmful to human body through the food chain. The hazards also emerged. Among the feed additives approved for use in my country, there are no varieties with high efficiency, low toxicit...
