Four measures to increase hens' egg production
A: Feeds with higher energy levels are very cold in winter, causing laying hens to fall. They need to replenish energy levels in the feed. Add 10 kilos of soybean oil per ton of feed or remove the bran from the feed formula and replace it with corn. can. B: Vaccination at a timely time Infectious laryngotracheitis, which is most susceptible to adult chickens, is a typical form of the disease. Therefore, the immunity of the disease should be immunized after 7 weeks of age to obtain good results. Poultry encephalomyelitis (AE) must be immunized at 10-15 weeks of age. Immunization before 10 weeks of age can sometimes cause morbidity, immunization after 15 weeks, and egg poisoning may occur.
Car Blanket is also called as auto blanket, as it is normally used for keeping warm in the car.
As a result, it is normally used in the open air. When people go out for a picnic and want to have a snap in the daylight or even spend the whole night outside, then the car blanket would be a best choice for you.
It uses 12V voltage, rather than AC power.
You just need to plug it into cigarette lighter of your car, and it the blanket will keep you warm.

Both vegetable oils and animal fats contain high metabolizable energy, with less than twice the metabolic energy of corn and 2.5 times more or more. The essential fatty acids vary widely. The essential fatty acids required by chickens are: linoleic acid, linolenic acid and arachidonic acid, of which linoleic acid is the most important. In the linoleic acid content of animal and vegetable fats and oils, the plant oil content is much higher than animal fats.
Immunization with Marek’s disease (MD) must be within 24 hours of hatching because chicks have the highest susceptibility to MD and their susceptibility to MD decreases with increasing age. Chickenpox is immunized after 35 days of age. Once it is immunized within 35 days of immunization, it must be immunized twice.
C: Provide processing of high protein content feed soybean cakes, peanut cakes, rapeseed cakes, cottonseed cakes: The processing methods of these cakes include pressing method, top extracting method and direct extracting method. Crushing method is the soybean, peanut, rapeseed, cottonseed after purification treatment, crushing, steaming, pressing and other processes, so that residual oil content reduced to 6% to 7%, and then grated cake to prepare for feeding.
D: The diet should contain more calcium salts in cages fed diets containing unequal amounts of salt, calcium, and phosphorus to study effects on production performance. A 33-factor permutation combination method was used in the case where supply salt and total calcium amount were 0.18%, 0.35%, 0.7%, and 2.25%, 3.5%, and 6.0%, respectively. When both salt and phosphorus are variables, the three factors of the above salt are combined with 0.45% or 0.7% of phosphorus, and the amount of calcium is 6%.
