The chicken has no sweat glands and its body temperature is as high as 41°C-42°C. Its heat dissipation mode is mainly respiratory heat dissipation, supplemented by surface heat dissipation. When the ambient temperature exceeds 28°C, the flock shows: 1) Reduced feed intake, increased drinking water, feces Thinning. 2 The body's endocrine reduction, metabolic disorders, eggshell thinning, protein thinning, soft shell eggs, shell eggs increased. 3 mouth breathing, wheezing, shortness of breath, drowsy, severe respiratory alkalosis or collapse. If you do not strengthen the feeding and management, and do a good job in preventing heatstroke, the chicken population will experience a serious decline in the egg production rate, the hatching rate of hatching eggs, and the hatching rate, which will bring huge economic losses to the chicken farmers. In the following, combining production practices, some measures for raising the temperature of the broiler breeder chickens in the summer to prevent them from cooling off are introduced. 1, reduce the breeding density, prevent heat accumulation. 2. Make changes to feeding methods for feeding and management of chickens. Feed the animals two times a day early and late to improve the feed intake of the flock. 2 In the hot season, the air humidity is relatively large, and more water is sprayed at the same time. The feed chute should be periodically cleaned to prevent the feed from agglomerating and moldy in the feed chute and ensure the feed is fresh. 3 To strengthen water spray and ventilation is an economical and effective way to prevent heatstroke in the summer. The open, semi-open house is sprayed with water in small quantities as many times as possible. Every time the chicken is sprayed, it is wet and the chicken house is wet but not slippery. Generally, 50% of the chickens in the flock should be considered for breathing. Water spray. Two rotations per day using disinfectant water to disinfect the chickens, reduce the deposition of cobwebs and dust in the house, reduce the dust in the house, purify the air, reduce the propagation of harmful bacteria, and kill bacteria and viruses in the air and on the surface of cages, Reduce chicken manure fermentation. In the hot weather can reduce Sherwin 3 °C -4 °C. Install a fan inside the house to increase ventilation, increase the amount of heat that the chicken's body surface heats, and at the same time promote the evaporation of water and take away heat. 4 To ensure the clean drinking water of chickens, add anti-stress drugs such as vitamins and electrolytes in drinking water to reduce the stress of chickens and increase resistance. Water pipes are often flushed to ensure that the birds are clean and drinkable, preventing the propagation and spread of harmful microorganisms in the pipes. (5) When the chickens are stopped on water, choose to do it in the morning or evening, and reduce the time of water stoppage. 6 Regularly disinfect, fly, and eradicate rats to reduce the spread of disease. 7 Greenhouse around the house to prevent direct sunlight on the body. Tile roof can be sprayed with lime, lime: white cement ratio of 5:1 into lime water, sprayed with a light pump to the roof, to be dry after the formation of a layer of white reflective layer, can reduce the temperature 2 °C -3°C.
Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months.
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
