What should the ducks pay attention to in spring?
When choosing a good grazing site for spring ploughing, in the rice planting area, you can reach the green manure field where ducks are ready to plant seedlings after ploughing. There are more natural animal and plant feeds in this field, such as grass, grass roots, earthworms, insects and so on. It is not suitable to graze in the field after transplanting, but not until the rice is harvested. Meticulous grazing in river network areas should make full use of river grazing, generally, it is appropriate to go up against the current when grazing, when the duck has enough physical strength and captures a lot of food. In the cold spring season, when you encounter windy weather, graze against the wind to avoid excessive heat loss of duck feathers caused by the wind. In the more forage

The nutritional function of protein in Pigs
Protein is the material basis of all life. Protein is the main component of all cells, accounting for 15%-21% of the body. The muscles, nerves, connective tissue and blood in the body are all based on protein. The hairs, horns, feathers and hooves on the surface of the animal body are composed of keratin. Enzymes, hormones, antibodies and products such as milk, meat, eggs and hair all have protein components. Proteins in animal organs and tissues are constantly updated in the process of metabolism. According to research, half of the protein in the body is updated in 6 to 7 months. So even if

Why salt in chicken food?
Chlorine and sodium elements are present in the body fluids, soft tissues and eggs of chickens, which maintain the acid-base balance of chickens, maintain the balance between osmotic pressure between cells and blood, and maintain the moisture content of chicken tissues. In addition, it is also a raw material for the formation of gastric juice and gastric acid, which can promote the activity of digestive enzymes and play a major role in the digestion and absorption of fat and protein. Salt can improve the palatability of diet, stimulate appetite and improve feed utilization. Therefore, salt is both an essential nutrient and a flavoring crystal. If the chicken's diet is insufficient in salt, it will cause

Causes of failure of Pig Immunization
(1) the immunization procedure is unreasonable. Scientific immune procedure will produce good immunity, if the immune procedure is unreasonable, its immunity will be reduced accordingly. According to the routine surprise immune injection in spring and autumn, because of the leakage of prevention and injection, those who should be vaccinated can not be immunized, resulting in the disease of some pigs. (2) the epidemic prevention system is not strict. Some epidemic prevention workers and pig breeders do not carry out immunization for fear of death caused by the reaction of piglets after vaccination, resulting in a decrease in the epidemic prevention density of pigs.

Clinical manifestations, prevention and treatment of heat stress in chickens
(1) the tolerance of chickens to heat. Because chickens have physiological characteristics such as high body temperature, exuberant metabolism and no sweat glands, the ability to tolerate high temperature environment is low, so high temperature has become the most harmful stress factor in chicken stressors. According to relevant measurements, the best digestion temperature for laying hens raised in China is 21-24 ℃, the best laying temperature is 15-20 ℃, and the relative humidity is 60% Mel 65%. When the egg production is above 28 ℃, the egg production decreases, and 1 ℃ per liter, the heat dissipation decreases, and the feed intake decreases by 1.6%, and 3% at about 30 ℃.

Effect of airflow on pigs
The motion of air molecules is called air flow, and the air flow that moves horizontally is called wind. The air flow in the atmosphere is caused by the uneven temperature distribution on the earth's surface, and the air molecules flow from the region of low temperature and high pressure to the region of high temperature and low pressure. In weather, the wind speed and direction are often described. The wind speed is the distance of the wind movement per unit time (m); the wind direction is the direction of the wind, expressed in 8 or 16 directions, and the wind direction frequency chart (wind direction rose chart) is drawn according to the probability of the wind appearing in each direction.
