In order to improve the success rate of livestock breeding, several feed additives that help to enhance the reproductive function of breeding animals are described below. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

1. Pine needles. Pine needle powder is the leaf of pine tree, which is not only rich in nutrients (including crude protein 8.96%, crude fat 11.1%, crude fiber 27.1%, nitrogen-free extract 41.5%, ash 3.43%, vitamin A content 950-2203mg/kg, also rich in Vitamin C, vitamin E and copper, zinc, selenium, cobalt and other mineral elements), and for the male animal has the effect of increasing the amount of semen secretion, thereby enhancing its reproductive performance. According to the test, adding 2.5% pine needle powder to the rabbit diet can improve the sexual desire and breeding ability of the rabbit, promote the normal estrus and ovulation of the female rabbit, increase the conception rate by 6%, and increase the litter rate by 9.27%. Increase by 28%, increase the birth weight by 7.2%; add 4% pine needle powder to the diet of the boar, which can increase the sperm production by 8% to 10%. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

2. Malt. Malt contains more vitamin E, which has the effect of improving reproductive function and improving semen quality in male livestock. Dosage: 150 grams per day for pigs, 40 grams for rabbits, and 10 grams for leeches. According to the test, the wheat germinated for 2 to 3 days was mixed into the feed and fed to the female rabbit. It was fed twice a day for 20 to 30 grams, and the estrus was observed even after feeding for 3 days. It is worth noting that malt has a retort effect and lactating rabbits should not be used. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

3. Carrots. Cut the carrots into fine diced and mix them in the feed of the female rabbits. Feed twice a day, 50 to 100 grams each time. After two days, they will estrus. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

4. Eggs. During the breeding season, 5 eggs are fed to the males every 3 days, which can make the livestock sexually strong, improve the quality of the semen, increase the vitality of the sperm, and thus improve the conception rate; before the estrus, use 5 eggs, 10 grams of sulfur, Mix well with warm water, once a day, even for 3 days, to help conceive. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

5. Trick or treat. It is rich in amino acids, minerals, vitamins and more cephalin, lecithin and hormones, which promote the formation of sperm. Dosage: 20 pigs at a time, 5 rabbits, and 0.5 water leeches. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

6. Freshwater shrimp. Freshwater prawn is warm and sweet, and it is a high-calorie feed. It has the effect of strengthening kidney and strengthening yang and strengthening male function. For boars with less sexual desire, 100 grams per day, cooked and even soup, even served 2 to 3 times, can greatly improve the success rate of breeding. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

7. Cocoon. It is rich in protein, fat, calcium, phosphorus and 12 kinds of amino acids. It has the effect of enhancing sexual desire and improving sperm motility for male livestock and poultry. Dosage: Chickens account for 5% to 10% of the diet, rabbits account for 3% to 5% of the diet, and leeches account for 10% to 20% of animal feed. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

8. Animal brain. The fresh brain of various healthy animals contains a large amount of cephalin and amino acids, which enhances male functions, promotes reproductive organ development, and promotes sperm production. Dosage: 100 grams of pigs, 25 grams of rabbits, 3 to 5 grams of water, cooked after feeding. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

9. Placenta. The fresh placenta of various healthy livestock contains placental globulin and various hormones, enzymes, and active substances such as erythropoietin and interferon, which enhances sexual desire, promotes testosterone secretion, increases ejaculation, increases sperm density, and reduces sperm deformity rate. Prevent testicular atrophy and other effects. Dosage: 50 grams of pigs, 10 grams of rabbits, 3 to 5 grams of water. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry

10. Vitamin E. Vitamin E, also known as tocopherol, anti-fertility vitamins, fertility vitamins or anti-fertility factors, can promote sperm production and activity; when animals lack vitamin E, testicular degeneration shrinks, sperm movement abnormalities and even can not produce sperm. Therefore, it has a good effect on improving the reproductive performance of animals. According to the study, the addition of vitamin E to the boar diet can improve the sperm production and fertilization ability, which can improve the conception rate. Vitamin E supplementation in the ram diet can increase the ejaculation volume, semen concentration and sperm motility of the ram. Achieve the effect of increasing the conception rate and lambing rate of the ewes. fG8 China Feed Industry Information Network - based on feed, serving animal husbandry
