How to treat egg breeders with high calcium gout
Most breeder farms have their own feed processing settings. In comparison, their own recipes, raw materials they purchase, and their own processing to control their own production storage time, this is more sure to adjust the nutritional needs of breeders at any time to ensure the accuracy of feed nutrient intake. In this regard, because of the internal management of the self, it is relatively safe to use, but it can also be more extensive and there will be times when we are negligent. If we do not do well, we will also cause undue losses to the breeding chickens. Here is a case of gout caused by high calcium in an egg breeder who had participated in consultations for reference in the industry.
Some 3000 breeds of Roman egg breeders on a farm show signs of slow growth, lameness, and laziness on 160 days of age. Some of the chicken joints are swollen on the visual inspection and show slow movement, unstable standing, poor appetite, and loose feathers. , Thin, row of white semi-mucoid thin stool. The continuous use of drugs such as ciprofloxacin, kanamycin, and florfenicol were not effective. Add 3 times more than the constant amount of multivitamins in the feed, plus AD3 powder to kidney detoxification medicine drinking water, but also not improved. The egg production rate was only 15% at 220 days.
Treatment: This kind of chicken farm is replaced with bone meal, supplemented with the increase of bran content (phosphorus source material) in a certain period of time. Kidney swelling detoxification drug treatment, so that large groups of hens recovered, egg production rose, but has not seen the peak.
Many breeder farms always think that to ensure the quality of eggs, especially the quality of egg shells, it is necessary to use bone meal or shell powder. It is believed that if only mineral sources of calcium such as stone powder are used, eggshell quality is unstable; Gout and pull lime-like excrement; but for the doping of animal-like calcium sources such as bone meal and shell powder, it is impossible to identify them. I learned from interviews that in some areas, some small egg breeder farms use stone powder ( Some use calcium hydrogen phosphate powder as a calcium source for chickens, and the effect is also good. Therefore, broiler breeders, egg breeders, etc., in the case of bone powder quality can not be determined, you can consider completely using mineral calcium source, but should pay attention to the actual utilization. Generally speaking, the stone powder contains about 36-38% calcium, which is similar to the shell powder, but the absorption rate and palatability are far less than the shell powder, so we must add more, such as the 9% of stone powder that can be used in some chicken farms. +1% light calcium powder; others use stone powder, the amount of 7.5% -8.5%. In addition, we must also consider the chicken's age. Generally, the absorption rate of calcium in chickens will decrease as the age increases. From chicken to mid-lay, the absorption rate for calcium is 55-60%, and after mid-term it is 40%. about. It can also be calculated that the amount of calcium required for laying hens should reach 3-4.5% in the feed. Alternatively, an adult hen needs 0.17 grams of calcium per day to maintain body condition and an egg produces about 2.2 grams (calcium). Therefore, each egg produces 4-4-4 grams of calcium.
