Phosphorus rich rocky lick brick significant efficacy: 1: solve the problem of breeding of female animals 2: extend the peak period of lactation; improve milk production. 3: Extend the life of female animals; 4: improve the comprehensive health index, reduce the incidence of dairy cattle 5: Pica disappears (gnawing wood, licking hair, licking urine, gnawing plastic) and the fur is smooth. 6: to promote food digestion, improve feed utilization, saving concentrate.
In the hot summer,heat stressIt is easy to cause reproductive obstacles in ewes, such as the decline of conception rate, lambing number and lactation performance, and the increase of abortion, dystocia and stillbirth. The growth rate of fattening sheep is slow, which seriously affects the economic benefits of sheep industry.
Causes of stress
Stress refers to a series of non-specific reactions or tension caused by the body of livestock and poultry under the stimulation of adverse environment. There are many factors that cause stress in sheep production.
① Climate:Sudden climate changes, high temperature, low temperature, wind, especially in the heat stress caused by high temperature on the breeding ram and breeding ewes the greatest damage.
② Management:Catch sheep, turn herd, transport, crowded, trample, weaning and sudden changes in the living environment, tail and other strong stimulation.
③ Feeding environment:Feeding density is too large, harmful gases (NH3, H2S, CO2, etc.) concentration is too high, too much dust and pathogenic microorganisms do not pay attention to spray disinfection, ventilation and so on.
④ Feed nutrition:Sudden changes in feed type, quality, quantity, and feeding times. Unreasonable formula, long-term lack or excess of certain nutrients.
Effects of High Temperature Stress on Sheep in Summer
Under the stimulation of continuous high temperature in summer, the digestive tract function of sheep will be weakened, endocrine disorder and liver detoxification function will be reduced, resulting in decreased resistance, body heat balance will be destroyed, and in severe cases, body temperature will rise and sheep will be in a coma. Sheep heat stroke.
High temperature in summer is the most harmful to the reproductive performance of breeding sheep. On the one hand, heat stress reduces the sexual desire and semen quality of rams; on the other hand, high temperature has serious adverse effects on estrus, breeding, pregnancy and lactation of ewes, reducing the fecundity of ewes.
In the high temperature environment in summer, the appetite of sheep is poor, the feed intake is reduced, and the growth rate and weight gain are also reduced. Therefore,Lodge lick brick can supplement the daily needs of cattle and sheep minerals and major trace elements, improve the health of cattle and sheep, speed up the growth rate, improve economic efficiency.
Phosphorus-rich Rocky Lick BrickSignificant efficacy:
1: solve the problem of breeding of female animals
2: extend the peak period of lactation; improve milk production.
3: Extend the life of female animals;
4: improve the comprehensive health index, reduce the incidence of dairy cattle
5: Pica disappears (gnawing wood, licking hair, licking urine, gnawing plastic) and the fur is smooth.
6: to promote food digestion, improve feed utilization, saving concentrate.
Management Measures of Raising Sheep in Summer
In summer sheep production, it is very important to take effective feeding management measures to improve the microclimate of the sheepshed and create suitable environmental conditions for sheep.
1、strengthen nutrition
Improve dietary nutrient concentrations, especially energy, protein and vitamin levels. Under high temperature, the decrease of feed intake of sheep is easy to lead to insufficient nutrition supply, and the nutritional needs can be ensured and heat stress can be properly alleviated by increasing the nutrient concentration of the diet.Low phosphorus content in the feed leads to a high rate of ground conception and a high rate of rebreeding.It is recommended to add phosphorus-rich lodge lick bricks to ewes, and high phosphorus content helps to supplement the phosphorus loss during milk production. A variety of major trace elements such as phosphorus and calcium work together to promote strong bone growth.
2、Strengthen ventilation
Strengthen ventilation to promote evaporation and heat dissipation of sheep body. In hot summer, doors and windows should be opened to strengthen air convection. It is better to set up ground windows in ewes houses, and iron fences or flower walls should be used in sheep pens to facilitate effective ventilation of ewes living and resting areas. Conditional sheep farms can be installed according to the actual situation of the sheep with air conditioning or longitudinal negative pressure mechanical ventilation of the overall control facilities, and with a wet curtain cooling system, can effectively reduce the ambient temperature inside the house.
3、Adjust the timing of feeding and breeding utilization
In summer, feeding and breeding should be carried out when the temperature is low every day (such as morning or night). The feeding times can be appropriately increased, the use of wet mix feeding and appropriate supplementary feeding green juicy feed, in order to improve the appetite and feed intake of sheep.
4、Reduce the feeding density of flocks
In order to reduce the stress, the feeding density of sheep can be appropriately reduced in summer, and the number of times of changing flocks can be reduced. When it is necessary to change flocks, it is best to choose when the temperature is cooler in the day. In addition, attention should be paid to the timing of the sheep deworming, scabies and other ectoparasites infection will make the sheep irritable and aggravate the adverse effects of heat stress.
5、Sheep Shade
Do a good job in the design of green shading, ventilation and heat insulation around the sheep house. The sheep house should be built to be warm in winter and cool in summer. The site should be located in a place with high dryness and facing south. The sheep house should not be built too low. It is better to set up a thermal insulation layer on the roof and whiten the outside of the wall to enhance the reflection ability of solar radiation.
