Etiological diagnosis and analysis of pig bite rack
In the process of pig breeding, the phenomenon of pig bites (including tail biting) often occurs, especially the lean pigs which grow fast and can not keep up with feeding and management are more likely to occur, and the wound is inflamed and ulcerated, which affects the production of live pigs. caused a lot of economic losses. Here, briefly talk about the inducement of pig bites and solutions for reference. The main results were as follows: (1) the inducement of pig bites 1.1 the feeding density was high (piglets > 3 / m2), the feeding trough was narrow, and the conflict of contact was frequent. 1.2 single

Etiological analysis of gout in chickens
Gout is due to the disturbance of uric acid metabolism in chicken body, the increase of uric acid concentration in blood and the excretion of a large amount of uric acid through the kidney; renal damage and renal function decline caused by various reasons further lead to the obstruction of uric acid excretion and the formation of a metabolic disease of uric acidosis, which mostly occurs in broilers and caged chickens. The main causes of chicken gout are as follows: 1. Lack of VA in VA can protect mucous membrane. When lacking, it can make keratosis and squamous metaplasia of renal tubule, collecting duct and ureter. Due to the epithelium

Prevention and treatment of heat radiation disease in pigs
In 1996, the town of Waisha set off an upsurge of raising pigs. Due to the lack of funds, there are more miniature pig farms. With a certain scale, there is only one with an annual output of more than 1000 heads, 8 with an annual production of several hundred heads, and more farm-style pigs with an annual output of dozens of heads. Sows are mainly grown-up, large-length hybrid offspring. Generally speaking, due to the small pig house, poor equipment, lack of ventilation, stuffy inside, pig shit, smelly urine and other factors, those obese non-pregnant sows or pregnant sows often cause heat ejection every year during the hot June-September period. If it is not found in time

The reason why pigs grind their teeth at night
Pigs grind their teeth at night for many reasons, and corresponding measures should be taken to eliminate them. A single feed is best for pigs to feed formula feed, because the various nutrients of formula feed, such as minerals, trace elements and so on, are reasonable. Concentrate feed should be matched with green roughage, and appropriate amount of minerals and trace elements should be added, such as 1% 2% mineral feed, such as bone powder, calcium hydrogen phosphate, eggshell powder, etc., and 0.25% 0.5% salt should be added to the diet, which has a certain effect on preventing pig molars at night. Or every day.

Talking about the Health Care Technology of fattening Pigs
Small peptide nutrition is used to promote the growth of finishing pigs, and the application of "dazhuangsu" or "dazhuangsu-B" to eliminate mycotoxin in feed can improve the disease resistance of the body and greatly reduce the occurrence of disease. in addition, it can eliminate ammonia, hydrogen sulfide and asthma in the barn, control respiratory disease syndrome, shorten the feeding period of more than 10 days, and improve feed conversion rate and meat quality. According to the previous view of small peptide nutrition and its health care, the digestion of protein is digested into a single free amino acid in the intestine, and then absorbed.

Remember not to throw cold water on pigs in summer
The temperature is high in summer and pigs are often hot and gasping for breath. Some farmers are worried that the pig will have a fever problem, so they throw cold water on the pig in order to cool it down and make the pig feel more comfortable, but they do not realize that this is harmful rather than beneficial. Hot panting of pigs is caused by poor perspiration and lack of heat in the body for a while. If cold water is thrown on the pig at this time, due to strong cold stimulation, the sweat pores of the pig's whole body contract sharply, the heat in the body is blocked, and the body temperature rises abruptly, causing high fever and inflammation of the lungs in the pig, and death in the pig. Therefore, it must not be the height of summer.

Study on processing technology of frozen surimi
Frozen surimi is a new type of raw material for processing fish surimi, which is mainly used for processing surimi products and conditioning frozen food. Frozen surimi processing technology is a new technology developed by Japanese fishery researchers using narrow cod as raw material from 1950s to 1960s. Frozen surimi should be frozen in the shortest possible time. A plate freezer is usually used, the quick-freezing temperature is-35 ℃ and the time is less than 4 hours, so that the central temperature of surimi can reach-20 ℃. The lower the temperature of frozen surimi

Introduce three methods of catching "hot water fish"
First, the pulling net method is a common fishing method to catch "hot water fish" at present. The net generally uses nylon net or the middle part uses nylon net, which requires that the length of the net is about 1.5 times the width of the pool, and the height of the net is about 2 times the depth of the pond. The advantages of this fishing method are as follows: first, there are a wide range of fish in the pond, which can meet the requirements of different fishmongers; second, in the process of pulling the net, the sediment and pond water are stirred, which plays the role of fertilizer and aeration. Of course, this method of starting arrest also has obvious shortcomings: first, pull

Identification of Easily Mixed Species of Famous Fish
With the development of socialist market economy and the improvement of people's living standard, the development of fishery production has taken off, especially in recent years, the development of famous fish is extremely rapid, but because some famous fish are very similar in appearance, it is difficult to identify them, which causes certain difficulties for farmers and consumers to purchase and identify them. 1. The pectoral fins of Pelteobagrus fulvidraco, Pelteobagrus longatus, Pelteobagrus vachelii, Pelteobagrus lustre and Pelteobagrus lustre are hard.

Fishing should be fastidious in autumn
First, pay attention to the weather: autumn dragnet fishing must choose sunny days, cool weather, pond fish do not float around the dawn, because at this time the least impact on the fish in the pond, but also in time to supply the fresh fish caught in the morning market. Haze, muggy weather is not suitable for net fishing, so as not to cause a large number of dead fish. In addition, it is not appropriate to catch fish in ponds when they have floating heads or fish diseases. Second, feed restriction before fishing: the oxygen consumption of fish increases after they are full, and they will be frightened, jump and run away when they are caught in the net, which is easy to cause death.

Measures for intensive cultivation of fish fry in autumn
First, improve the growth environment. After several months of breeding, the water quality of the ponds that used to cultivate fish species is gradually aging, which is disadvantageous to the growth of fish species. Efforts should be made to improve it. One is to add new water, the water in the original pond can be released into 1 beat 3-1 tap 2, and then add new water with the same temperature. Second, fertilization, fermented manure can be properly applied, generally about 150 kg per mu, once every 7-10 days, a total of 500-750 kg, generally adopt the method of small pile stacking or sprinkling in the whole pool. In addition, it should be appropriate

Four ways to get rid of wild fish
When adding water, changing water and feeding water plants in intensive ponds, it is inevitable to mix with wild miscellaneous fish or eggs, such as meal strips, wheat ear fish, crucian carp, Loach, grass shrimp and so on. These wild miscellaneous fish not only have strong grazing ability, large food intake and low economic value, but also reproduce fast. in addition, snakehead, catfish and other carnivorous ferocious fish can also swallow farmed seedlings. Therefore, various measures must be taken to eliminate wild miscellaneous fish in culture management. 1. Kill the wild miscellaneous fish in the pond beforehand, drain the pond water before restocking, let the bottom of the pond freeze in the sun for a period of time, and then add 20: 3.
