Classification and cultivation of Edible Grass for cattle, Sheep, Pig, Rabbit and Goose
1. It is recommended to feed cattle: Mexican corn, alfalfa, tall fescue, pennisetum, Sudan grass, etc., should not be planted with succulent leaf forage with high crude fiber content. Mexican corn is suitable for planting in areas with annual rainfall of more than 800 mm and frost-free period of more than 180 days, and can be cut once a month when the plant height is 1.5 meters. Forage dry matter contains 9.5% crude protein, 2.6% crude fat and 27.3% crude fiber. The stems and leaves are crisp, tender and juicy, sweet and palatable, and are also suitable for silage or drying hay.

Prevention and treatment of common blight in cattle after flood
It is hot, rainy and flooded in summer, which is the season with high incidence of bovine epidemic disease. Therefore, attention must be paid to the prevention and control of cattle susceptible diseases in this period. Anthrax is an acute zoonotic disease. Cattle are most susceptible to anthrax. Blood-sucking insects often occur when they are active during the rainy season and after flooding. The disease is characterized by sudden high fever, coma, purple conjunctiva, trembling all over the body, molars, spasm, natural pore bleeding and other symptoms.

Technology of low pollution Diet for Pigs (Research Progress)
[abstract] it has been a common goal for producers and nutritionists to maximize the production performance of each pig. Therefore, the general diet has little or no consideration for the excretion of nutrients, resulting in the excretion of excess nutrients (mainly nitrogen and phosphorus) with feces and urine. In recent years, the public has paid more and more attention to the environment. Through nutrition technology, to improve the feed conversion efficiency of pigs and reduce the discharge (feces and urine) has become a hot spot in the current pig science and nutrition research.

Prevention and treatment of Porcine circovirus Type 2 infection
So far, there are no effective measures to control and eliminate other diseases caused by porcine circovirus type 2 infection, and there are no effective commercial vaccines and drugs to prevent porcine circovirus type 2 infection. Moreover, porcine circovirus type 2 infection is very resistant to conventional disinfectants, which brings difficulties to the purification of pig farms. At present, comprehensive control measures should be taken. 1. Change and improve the feeding mode to achieve all stages of pig production, so as to avoid mixed feeding of pigs of different ages.

Cutting pig eyelashes can prevent pigs from jumping.
If a pig jumps in a circle, its upper eyelashes can be cut off. In this way, when the pig looks up again, its eyes will be stimulated by wind, light and dust, causing the pig to feel a sense of fear. If its eyelash is long, it can be cut off until it does not jump in a circle. However, it should be noted that the pig's upper eyelashes should not be pulled out to prevent the pig from having a stroke.

Diagnosis and treatment of bovine actinomycosis
In early May 2006, a cattle farmer in Munong Village, Bahuang Town introduced 42 cattle with an average age of 8 months from Shandong Province. Without isolation and observation, they were directly put into pens and mixed with the original 20 cattle, thus causing 7 cattle infected with actinomycosis. 1. The disease occurred in one cow in the introduced herd. After long-distance transportation of mixed herds and transportation to the destination, the introduced cattle were not isolated for observation and directly entered the breeding house, resulting in the spread of the disease. From 1 head at the time of introduction to early July

Chickens and ducks pluck easily
1) when slaughtering chickens and ducks, first fill them with two tablespoons of white vinegar or white wine, wait 5 minutes for 10 minutes, the pores of the chickens and ducks become dilated, then slaughtered, then scalded with hot water, the feathers of the birds can be easily removed. 2) boil a pot of boiling water, add a spoonful of vinegar, put the slaughtered chicken into the pot, soak the chicken in water, turn it over and take it out after a few minutes. 3) do not boil the hot duck water, because the duck feathers shrink when exposed to 100 ℃ boiling water and are difficult to pull out. The correct way is to slaughter the duck when the water is boiling to blistering.

The main causes of non-disease death of koi and its solutions
1. Water quality problems at present, tap water is the main water for household culture of koi, and the quality of tap water sources in some areas is relatively poor. Waterworks use a large number of disinfectants and detergents during treatment, and the fish will be poisoned if they do not adapt to the change of water. that's why there are water treatment links such as sun water and aeration before changing water. Chlorine in water is the main cause of fish poisoning. In the process of changing water, the method of gradual addition should be adopted as far as possible, the change of water should be completed several times, and sodium thiosulfate should be properly put into the water to remove the residual chlorine.

Russian experts find new fish additives
Russian fish culture experts have recently found that chitosan, a biopolymer extracted from the crustaceans of marine crustaceans, can be used as a fish feed additive to make fish feed more suitable for handling, and fish will become fatter if they eat feed containing chitosan. General fish feed is processed into loose particles, but it is easy to break up due to friction or extrusion in the process of transportation, and it is quickly expanded and split due to soaking in the water, resulting in waste. Therefore, when processing fish feed, it is necessary to add feed adhesion components to increase.
