Spring is the breeding season for livestock breeding. In order to improve the success rate of livestock breeding, the following are some of the feed additives that help to enhance the reproduction performance of breeding animals (equivalent to livestock “Viagraâ€).
1. Pine needles. Rich in nutrients, containing 8.96% crude protein, 11.1% crude fat, 27.1% crude fiber, 41.5% nitrogen-free extract, 3.43% ash, vitamin A content 950-2203 mg/kg, and also rich in vitamin C, vitamin E and Copper, zinc, selenium, cobalt and other mineral elements, but also can increase the semen volume of breeding stocks and enhance their reproductive performance. According to experiments, the addition of 2.5% pine needle powder to the rabbit diet can increase male libido and mating ability, promote normal estrus and ovulation of female rabbits, increase fertility rate by 6%, and increase litter size by 9.27%. 28% increase, birth weight increase 7.2%; adding 4% pine needle powder in the diet of boar can increase the amount of sperm extraction 8%-10%.
2. Malt. Malt contains more vitamin E, can improve the reproductive function of male livestock, improve semen quality. Dosage: 150 grams per day for pigs, 40 grams for rabbits and 10 grams for leech. According to the experiment, the 2-3 day old wheat was mixed into the feed and fed to the female rabbits. The female rabbits were fed 2 times a day, 20-30 grams each time, and they were exposed to heat for 3 days. Note that malt has a back milk effect, and lactating female rabbits should not feed.
3. Carrots. Cut the carrots into small pieces and mix them into the female rabbit feed. Two times a day, 50-100 grams each time. After two days, the estrus will occur.
4. Eggs. Feeding 5 eggs to the broiler every 3 days during the breeding season can enhance sexual desire, improve semen quality, and increase sperm motility, thereby increasing the conception rate.
5. Trick or treat. Rich in amino acids, minerals, vitamins and more cephalins, lecithin and hormones, can promote the formation of sperm. Dosage: 20 pigs, 5 rabbits and 0.5 mink.
6. Freshwater shrimp. Sexual sweetness, is a high-calorie feed, there are kidney yang, strengthen the effect of male function. For boars with low sexual desire, 100 grams per day, cooked and soup fed, and even served 2-3 times, can greatly increase the success rate of breeding.
7. Silkworm cocoons. Rich in protein, fat, calcium, phosphorus and 12 kinds of amino acids, it can improve the libido and sperm vitality of males. Dosage: Chickens account for 5%-10% of the diet, rabbits account for 3%-5% of the diet, and leech accounts for 10%-20% of animal feed.
8. Animal brains. The fresh brain of various healthy animals contains a large amount of cephalin and amino acids, which can enhance male function, promote the development of reproductive organs, and promote sperm production. Dosage: 100 grams of pigs, 25 grams of rabbits, 3-5 grams of water, cooked and fed.
9. Placenta. The placenta globulin and various hormones, enzymes, and erythropoietin, interferon and other active substances are contained in the fresh placenta of various kinds of healthy livestock, which may enhance libido, promote testosterone secretion, increase ejaculation, increase sperm density, and reduce the rate of sperm abnormalities. Prevent testicular atrophy and other effects. Dosage: 50 grams of pigs, 10 grams of rabbits, and 3-5 grams of leech.
10. Vitamin E. Also known as tocopherols, infertility vitamins, and fertility vitamins, can promote sperm production and activity; when the animal lacks vitamin E, testicular degeneration, atrophy, abnormal sperm movement can not even produce. According to research, adding vitamin E to the diet of male boars can improve sperm production and fertility, which can improve the conception rate; supplementation of vitamin E in ram diets can increase ram ejaculation, semen concentration, and sperm motility. To achieve the effect of improving the conception rate and lambing rate of ewes.
