Cattle feeding urea depends on forage grass
Feeding urea to cattle, urea can be digested by microorganisms in the rumen of cattle to synthesize bacterial protein, instead of part of the protein feed, so urea is a high-quality protein supplementary feed for cattle. But urea is not a protein after all, and its utilization efficiency is affected by many conditions. Generally speaking, feeding urea to cattle should be determined according to the situation of forage grass. Urea can be added in winter and spring when wheat straw, dry corn straw and hay are the main coarse feed, but not in summer and autumn when green feed is the main feed. The experiment shows that the content of crude protein in feed is less than 11%.

Occurrence and prevention of pig bite and fighting
First, the cause of the pig bite phenomenon 1. The probability of contact and conflict among pigs with excessive feeding density is also high, and their activities are limited, which is the inducement of bite-and-fight phenomenon. In addition, there is a unique group order behavior, after grouping pigs, they will bite each other at first, and then establish an obvious rank relationship according to the strength of the physique. If the herd of pigs is too large, it is difficult to establish a position, resulting in frequent bites and fights with each other. two。 Feed nutrition imbalance the use of non-full price feed or the improper proportion of nutrients in feed, especially the protein and vitamins in feed

Diagnosis and prevention of chicken gout
Chicken gout is uricemia caused by disturbance of protein metabolism. First, etiological analysis. 1. Nutritional imbalance: when the content of protein and nuclear protein in the feed is too high, the sharp increase of uric acid in the body exceeds the excretion limit, thus depositing in the form of urate (mainly sodium urate) in the joint, visceral surface and subcutaneous connective tissue, causing a series of pathological changes. Especially in chickens with imbalance of calcium and phosphorus in feed and vitamin An and D deficiency, the disease is more likely to occur.

Harm and Countermeasures of Asthma in Pigs
Porcine wheezing disease is a serious pig infectious disease with high morbidity and low mortality, resulting in higher costs and lower profits in the pig industry. In China, for the same 100 kg pigs, the loss of infected pigs is 119 yuan more than that of uninfected pigs. Infection with Mycoplasma suis alone rarely causes death in pigs, but when infected with other bacteria, it will cause a long course of disease, difficult treatment, a decline in production level, and may lead to a certain mortality. Mycoplasma hyopneumoniae was found in 80% of pig lungs and 90% of pigs.

The feeding method of saving feed for chickens
The cost of chicken feed accounts for about 70% of the cost of raising chickens, so saving feed to reduce costs is the main way to improve the economic benefits of raising chickens. The following methods can be taken to save materials: 1. Raise fine varieties. The production performance of superior breeds of chickens is much higher than that of other breeds with the same age and the same feed consumption. At present, there are more than ten high-yield laying hens and broiler breeds in the world, most of which have been introduced in China. The laying hens adapted to the north are mainly Roman and Hai.

Pig arthralgia syndrome
[etiology] due to the dampness of the pig house, coupled with exogenous wind, cold and dampness, the meridians of the affected pigs were stagnated, and the qi and blood was stagnant. If the blood stasis is blocked, it will be painful, resulting in pain and paralysis in the hindquarters. The disease mostly occurs in winter and spring. Symptoms often occur suddenly, starting from the hindlimb and gradually extending to the abdomen and even the whole body. Suffering from pig lameness, local muscle pain, arch waist bundle walk, some like to lie down, drive reluctantly, but with the exercise time, the pain gradually relieved. Tenderness is common at the site of the disease, and the body temperature is usually about 38-39 ℃.

Persistence of transmission of porcine reproductive and respiratory syndrome (prrs) virus
Porcine reproductive and respiratory syndrome (PRRS) virus has a great impact on the economic benefits of the global pig industry. The disease increases mortality, reduces pig production performance and growth rate, and increases the cost of vaccines and drugs. Although many prevention and control measures have been put forward, their effects are still different after implementation, so these measures are not suitable for some pig farms. PRRS virus has long-term pathogenic infectivity and can spread horizontally and longitudinally. Fetuses in the womb and piglets before weaning are infected with the virus late and can be transmitted to

Disease prevention of fish before storage and transportation
As the saying goes, "if you want to buy a chicken, you have to buy a fish." And many fish farmers after a year of hard work, to the adult fish sales season has encountered problems, fish are not resistant to storage and transportation, the whole body is congested, and even dead fish. At this time, most farmers think that there is something wrong with the feed. Indeed, in order to unilaterally reduce the feed coefficient and improve the growth rate of fish, some feed manufacturers add hormone or hormone-like drugs, such as olaquindox, to the feed, resulting in the above phenomenon in the process of fish storage and transportation. But it makes the fish intolerant of storage and transportation.
