To feed sows (more pig knowledge, click on the right side of the pig), feeding high protein diets can significantly improve body weight and fitness, British researchers have found. From the two week before the sow's delivery, feed the sow with high protein diet containing more than 18% of the crude protein until weaning, and then feed the normal diet of low protein after weaning. This method not only can improve the birth, weaning weight, reduce the prevalence rate, but also shorten the reproductive cycle, improve conception (please click on the right side of the pig more knowledge, more pig technology) rate and litter size. A Japanese company developed a system that allows plankton to be cultured as bait quickly and rapidly. The system can increase plankton by about 6 times in 10 days. System (more pig knowledge, please click on the upper right corner of more pig technology) consists of 1 100L tank, heating and cooling devices, mixers and pumps. In a certain amount of plankton in the water, (more pig raising knowledge, click on the upper right corner of the pig more technology) into the culture medium, and then enter the air, control temperature and stir, after about 10 days training bait can support 15 thousand fry food. The system is suitable for both marine aquaculture and freshwater aquaculture. Additives to promote the growth of fish and shrimp, German scientists found that adding a certain amount of inositol in the fish commodity feed can significantly promote the growth of fish and shrimp. Per kg of feed add inositol was respectively: carp 400 mg to 500 mg, 300 mg to 400 mg of salmon, 200 mg to 300 mg of shrimp. The use of solar energy according to the size and amount of pig pig built a number of moderate size solar barn. Quanshe north wall seal, south wall mounted glass window, the top covered with plastic film, and with good ventilation. In the sunny day sheds light absorbing heat and energy storage, without sunlight thermal insulation. The use of solar energy housing pigs, weight gain increased 20% ~ 30% fold than ordinary, can shorten the breeding cycle of pigs. Because the physical consumption caused by cold is reduced, the feed consumption and the feeding cost are reduced, and the economic benefit is improved. Japanese researchers have developed a technique to clone cattle by embryonic colony culture. The technique was successfully cloned by implanting nuclei into unfertilized eggs after embryonic implantation. In theory, 1 embryos can be cloned from 200 embryos, but only 30 to 60 can be cloned at present, the researchers said. The technology is expected to be applied to the production of good quality beef cattle. Calciumformate piglets according to researchers in Finland test, adding 1.5 grams of calcium formate within weeks after weaning diets, the growth rate of piglets increased by more than 12%, the feed conversion rate increased by 4%, and can reduce the incidence rate of piglets. VE to sow more Zi according to the study of German experts, from the third day weaned piglets, sows in diets containing 200 mg of vitamin E and 400 mg carotene, to sow estrus, the number of the two kinds of additives to reduce 50%, and fed to the 21 day after pregnancy, the 21.9% increase in the number of young sows. The pig moves to fatten the University of Missouri in the United States. Experiments show that fattening pigs can increase appetite and speed up growth. But the replacement ring is not too often, once a month is appropriate, the size of the circle, the form should be basically the same, but each group of pigs do not arbitrarily change or add new pigs. Drinking oxygen water to increase the weight of piglets, according to foreign information, the use of oxygen containing water to feed weaned piglets, drink 1 times every 5 days, daily gain of up to 200 grams ~250 grams. Oxygen containing water is made from common water and added to a certain proportion of oxygen. Pig feed beet weight gain, a British pig farm with 400 Hybrid Pigs to do experiments, adding sugar beet in the diet, weighing 13 kg to 32 kg of pigs, adding 15% of Beet Powder; 32 kg or more to add 20%. The results showed that the feed conversion rate was improved, the slaughter period was shortened, and the meat quality was improved. Many pig farms now add beets to their diets. Transform of the light at the head of a number of egg laying hens in April, the day period to 28 hours, and at 12 hours of light and 16 hours of dark interval transform light, can make the egg production increased by 10%, and the eggshell strong are small eggs. The new formula, net lean meat, developed a new formula for lean chicken production abroad. On the basis of the general full price feed formula, the crude protein content was 38%, and another ammonium polyphosphate or ammonium sulfate 0.54% was added. Feeding this kind of feed can make chicken lean meat and reduce fat deposition. Call sow music a Japanese pig and chicken fast growth of animal husbandry field test recorder regularly broadcast lactation, milk can effectively shorten the time interval, and can avoid the phenomenon of dead piglets of sows. The results showed that the average time of feeding was 44.7 minutes, and the average weight of weaning was 7 kg. The average time of feeding was 50.6 minutes and the average weight was 6.2 kg without playing the recording group. The recorded piglets did not die from a crush, compared with 8.7% in the control group. When the chicks hatch, they play the recording of the chirping of young chickens out of the shell, which can make the chicks out of the shell in good order and improve the hatching rate. In a day of 12 hours of play or make the chicken sweet serenade, every 1 hours of rest for 1 hours, 7 weeks ~8 weeks. The daily gain of broilers increased by 3%, and the laying rate of hens increased by 10%.
