Quick-feeding of broiler chickens means that the broilers are reared in brooding and rearing, that is, the chicks are raised in the broiler house until they are 4 weeks old, and then transferred to the rearing house for rearing. This way, the broilers are accelerated to turn around the broilers. The batches also increased the utilization rate of chicken houses and reduced the occurrence of epidemics. The economic benefits were quite significant. Practice has proved that this feeding method can raise 8 to 9 batches of broiler chickens a year, and brooding, rearing with the same housing, can only raise 4 to 5 batches a year. The breeding method is described as follows:
1 Variety selection At present, the main fine inner chicken breeds are: Aviin, Kaunis, AA, Star and Red Jade. These species have high survival rate (up to 95% to 98%), rapid growth (up to 2 kg in 8 weeks of age), low consumption of material (feed ratio 1.8 to 2.1), and feeding throughout the year, etc. Advantages, breeders can choose according to local conditions.
2 The ratio of the sterilized brooding house and the finishing house is generally 1:2. The brooding houses can be replaced by ordinary houses, and they can be used after they are trimmed, cleaned and painted. The fattening house uses a wall outside the house and builds the remaining three sides with bricks or slabs. It requires a height of 2 to 2.5 meters. The length and width can be determined according to the amount of rearing, and the front and rear windows and the top are set. The brooding house and the finishing house must be disinfected before each batch of feeding. The method is: first clean the house, and then use 2% to 2.5% caustic soda water spray disinfection, and then press formalin per square meter of space to add water 14ml, into the container, will be 14 grams of potassium permanganate Put into it, you can carry out fumigation, close the doors and windows a week later, and then free for 2 to 3 days, you can start feeding.
3 Diet formula The diet of broilers should be high-energy, high-protein, full-price compound feed, and the proportion of various nutrients should be appropriate. 1 to 4 weeks of age require diets containing 2900 to 3,000 kcal per kilogram of metabolic energy and 22% to 23% of crude protein; 5 to 8 weeks of age require kilograms per kilogram of dietary energy to be 3100 to 3200 kcal, including Protein 19% to 20%. The diet can be composed of corn, sorghum, barley, wheat, rice bran, bran, soybean, pea, bean, rapeseed cake, cottonseed cake, peanut cake, bean cake, cocoon, fish meal, blood meal, bone meal, shell powder, and the like. 1 to 4 weeks old reference formula: corn meal 53.7%, bran 2%, bean cake meal 22%, cottonseed cake meal 6%, rapeseed meal meal 6%, fish meal 6%, bone meal 2%, shell powder 2%, salt 0.3%, and 0.25 kg of selenium auxin, 0.25 kg of multivitamin, and 100 olaquindox (crushed) were added for every 50 kg of feed. 5 to 8 weeks old reference formula: corn meal 57.7%, bran 4%, bean cake meal 23%, cottonseed cake meal 6%, fish meal 5%, bone meal 2%, shell powder 2%, salt 0.3% (additives Ibid.)
4 In the first 2 days after the chicks are properly fed into the broiler house, they can feed broken rice or corn grits and feed the cooked egg yolk (3 egg yolks for every 100 chicks). From the 3rd day, feed the compound feed. 1 to 2 days old chicks, the feed meal sprinkled on a plastic sheet, feed once every two hours; 3 to 10 days of age will be mixed feed coarse powder plus the right amount of water (hand fingers do not drip) After being steamed and fed, the chickens can be digested and absorbed; after 10 days of age, the dried feed meal can be directly fed into the strip feed tank. The number of feed troughs should be higher and lower, so that each chicken can be at the same time. Eat food, feeding 6 times a day; after 20 days of age (when the body weight reaches 0.25 kg or more), dry whole grain for the whole day and let any chicken feed freely. At the same time, provide plenty of clean drinking water.
5 Careful management For the first time, maintain proper temperature and humidity. In the first few days, the temperature in the house should be maintained at 35 °C ~ 32 °C, then down 3 °C every week, until it has dropped to about 20 °C. With suitable temperature, broilers are not susceptible to disease and grow faster. The humidity should not be too large, otherwise the bacteria and eggs will be easy to reproduce. The chickens are susceptible to aspergillosis and coccidiosis. Suitable relative humidity for broilers is: generally maintained at 65% to 70% in the early stage and about 55% in the latter stage. House humidity can be used for hygrometer determination. Second, do a good job of ventilation. The simple method of ventilation is to build a sunroof on the top of the house, or to open the window before and after, so that the air convection, but also can install a two-way fan. In a well-ventilated chicken house, people feel no ammonia smell and no pungent glare. Third, reasonable lighting and breeding density. The purpose of broilers to light is to extend the time of eating and speed up the growth. Experience has shown that it is best to give light 24 hours a day, and the light intensity is slightly stronger in the first 3 days to facilitate chicks to become familiar with the environment and gradually weaken afterwards so that the chicken can see the food. The reasonable rearing density per square meter is: 30 to 32 for 1 to 4 weeks of age and 14 to 16 for 5 to 8 weeks of age. Fourth, we must be diligent. The litter can be sawdust, glutinous rice, short straw, etc. Sand can also be used in summer. During the entire feeding period, litter is added as needed, and the matted litter can be used after being fluffed and loosened. In addition, we must promptly do a good job in the size, strength, and division of work, and constantly eliminate sick, weak, miscellaneous chickens, and carefully care according to their different circumstances to promote consistent growth of chickens. The brooding house can be used with 250-300 flocks, and fattening contains 400-500 flocks.
6 The epidemic prevention and control keepers should perform personal hygiene and wear work clothes and hats. Keep the brooding house, the finishing house and the surrounding environment clean and hygienic, so that the chicken body, feed, drinking water, food utensils, tools and litter are all six clean. It is strictly forbidden that personnel enter the shed to prevent the introduction of human germs. In addition, drug prevention and treatment measures, etc., are the same as those raised by ordinary methods.
Excretion is an important part of metabolism, however, due to various reasons, many patients will not be able to auto- urinate normally and smoothly. So we need to help urinate manually. Catheterization is a very common practice of nursing operations after closely observed and documented.
Yingmed offers you a series of catheter-related care products. For example: Silicone catheter, Urine bag, Urinal,Bed Pan .
Through the urine and stool, doctors can judge patients` condition. Yingmed also provided Urinal cups and disposable tubes for storage , then the urine and stool could be delivered to lab to do analysis. In addition, the urine analyzer will help the experimenter to get a correct data .
