"three methods" for fattening old and remnant cattle
Fattening old and residual cattle is an effective measure to give full play to the production performance of cattle and improve the economic benefits of raising cattle. Before fattening, cattle were first dewormed and vaccinated, and then intensive fattening was adopted, that is, fattening was achieved in a short period of time (80,100 days). (1) Rice water plus rice bran fattening 20 kg of rice bran per cow per day, adding 2 kg of rice bran and feeding the cattle after mixing. Other conventional feed allows the cattle to eat freely and gain about 1 kg per day. (2) Distiller's grains with concentrate fattening daily for each cow

Eight measures to prevent Chicken stress
It is reasonable to reduce the feeding density by using a set of equipment to support 100 adult chickens, and the feeding density should be 6-8 per square meter. After fixing the flock, do not casually throw new chickens into the flock. Careful transfer should be carried out at night. 2-3 days before the transition, an appropriate amount of antibiotics and vitamins should be added to the feed or drinking water. 1-2 hours before the chicken is caught, chlorpromazine should be added to each kilogram of feed, 30 mg per chicken, and 50 mg each for adult and adult chickens.

Pig pull sheep feces
There are many reasons for dry pig feces, such as high roughage content, classical swine fever, swine toxoplasmosis and so on. For specific reasons, it is recommended that you make further observation and diagnosis, or contact the local veterinary epidemic prevention department for consultation. Pigs with extensive feeding and management and poor feed conditions are prone to loss of appetite, slow action, dry and hard faeces into abacus beads, arch ground, brick gnawing, fecal eating and other abnormal phenomena. Etiology: first, the proportion of concentrate in pig diet is too high. The second is the deficiency of calcium and phosphorus in pig diet. Third, the proportion of cereals and legumes in pig diet is too large. Cereal

The fat and thinness of pigs can be regulated.
After nearly a decade of scientific and technological research, Chinese scientists have discovered the mechanism of differentiation and regulation of pork fat cells, and made a major breakthrough in the use of biotechnology to control pork fat content. In this study, cell biology, molecular biology and other techniques were used to determine and analyze the growth and development of adipocytes, adipose tissue metabolism and related genes among different types of pigs, and a series of research results were obtained. This major achievement has recently passed the achievement evaluation organized by the Ministry of Education.

The first priority in the management of infectious diseases in pigs
The emergence of new pig diseases forces us to re-evaluate the existing production system. If there is no vaccine, improved management methods must be adopted to control the disease; even if there is a vaccine, it may not work without management. This paper provides some basic methods to help pig farms adopt appropriate methods to control infectious diseases according to their respective conditions. The goal of disease control must be clear, the goal is to "control" the disease, not to eradicate the disease. In general, the control measure is usually to reduce the number of pigs in a reasonable way.
