Dr. Yang: Hello!
I am a professional chicken farmer. Long-term high temperatures can easily induce various diseases. The ratio of feed to meat is reduced, and the breeding efficiency is significantly reduced. Can you introduce some feeding methods and technical measures for summer broilers to improve the breeding efficiency of summer chickens? Thank you! Reader: Zhang Lei
Zhang Lei reader: Hello!
During the high temperature season in summer, chicken farmers should adjust feeding methods, pay attention to cooling and heatstroke prevention, guard against chicken heat stress, strengthen the prevention and control of chicken disease, and improve the comprehensive benefits of chicken breeding. The measures are as follows:
Provide a good breeding environment
First of all, it is necessary to improve the hardware facilities of the chicken house, and to strengthen the maintenance and reconstruction of old and inefficient equipment and facilities, and to upgrade and renovate all inapplicable equipment and facilities as far as possible so as to achieve the requirements of thermal insulation in winter and thermal insulation in summer. The superiority and inferiority of the chicken house's small environment directly affect the body's ability to resist pathogenic microorganisms, and the feed intake and weight gain of chickens. The improvement of the chicken house's small environment should be strengthened. The control of the environment in the chicken house is positively related to the level of feeding and management. Because the specific measures of feeding and management are often reflected in the management of details, it is important to adjust the management methods in a timely manner and improve the small environment of the chicken house. For example, to deal with the relationship between temperature and humidity in winter, the temperature difference between day and night can not be too large, otherwise the body resistance is reduced, easily stimulated by cold stress, resulting in a variety of bacterial and viral diseases. Large-scale chicken farms use ventilation systems in winter, so we must pay attention to the tightness of the chicken house and block the gap between the walls and roof of the house. In summer, the window used for natural ventilation is changed into a small air inlet. The size and number of air inlets should be matched with the exhaust fans to eliminate the dead angle of ventilation. Experience shows that if the management of this link is done well, the survival rate of chickens can often increase by 5%-10%. Appropriate increase of empty time can ensure the safety of chickens and product quality.
Feeding high quality feed
According to the growth and development of chickens and the requirements of the various stages of growth, provide different levels of full-priced feed, according to the appropriate adjustment of feed formulations in the season, to ensure the necessary nutritional levels of chickens, so that the chickens to spend a long summer. The quality of feed quality is the key to the success of chicken breeding. The cost of raising chickens is 70% of the cost of feed. Therefore, all effective measures must be taken to ensure the quality of feed and ensure that every chicken can eat fresh, non-polluting and mildew-free. A sufficient amount of feed. It is advisable to conduct microbiological examinations on feeds on a regular basis and find that unqualified feeds are handled in time Limiting the light and feeding time of broilers can not only reduce the incidence of ascites in broilers, but also reduce the feed-to-meat ratio, thereby reducing the cost of feeding.
Control common diseases
To do a good job of comprehensive epidemic prevention is an important condition for raising good chickens. The scope of comprehensive prevention measures is very wide, including the sanitation and disinfection of chicken coops, the management of chicken manure, garbage, and sewage, the timely isolation of diseased chickens, elimination of dead chickens. Incineration or shipment to chemical processing station. Control the spread of important infectious diseases, complete the immunization work according to the established immunization procedures and medication procedures, schedule, maintain the quality and quantity, regularly conduct preventive drug administration, and observe strict biosecurity measures. Control the environment of the chicken house to minimize stress and reduce the reaction intensity of the vaccine. When selecting vaccines, SPF chicken embryos should be used as vaccines, because ordinary eggs often contain immunosuppressive viruses, affect the body's immune response, reduce the survival rate, increase the cost of raising chickens. After the immunization, timely detection of the immune effect should be established, and a set of test data suitable for their own chicken farms should be established as a basis for future designated immunization procedures.
Sweet corn. The light green outer leaves of sweet corn are yellow grains, but also purple and yellow. The grains are small and round, the skin is thin and soft, tender, sweet and delicious.Contains carotene, zeaxanthin, with the effect of eye protection.
Sweet corn is most often boiled into soups. It is a favorite soup for children and adults, whether it is made into a clear corn soup with ribs or pureed with cream.
Corn is also a good choice for consumption during weight loss because of its high available energy. The metabolic energy of corn is 14.06 MJ/kg, with the highest being 15.06 MJ/kg, the highest of the cereal feeds. This is mainly due to the fact that there is very little crude fibre in corn, only 2%, while the nitrogen-free leachate is up to 72% and the digestibility is up to 90%; on the one hand, corn has a high crude fat content, between 3.5% and 4.5%.
So how do you cook a sweet corn?
1. Leave the leaves
If you strip the leaves off, the corn will lose nutrients and flavor when it cooks, so it's best to leave two thin leaves to make it easier to cook and have a nice aroma.
2. Soak
Soak the corn in cold water for 20 to 30 minutes before boiling, then boil it on high heat to give it a bit more chew.
3. Add salt
When the water is boiling, add a little salt to amplify the sweetness of the corn.
