“Bantouyan off off period for technology”

Bantouyan While keeping simple, breeding profit higher, but the low
rate of reproduction, laying a short, and therefore how to extend the
period allowed in the non-laying season is how to reduce the cost of
access to key high profits. Next will Bantouyan off perinatal farming
methods introduced to the reader.

1. To the water for drought support Although the surface can be
reduced by breeding Bantouyan cleaning workload, but would lead to
water pollution, summer water bodies become dark autumn release bad
odor, severely affecting Bantouyan health. Thus, at its July platoon
dry off postnatal water, cleansing and disinfection of the pond, then
the appropriate fish, the water lettuce, etc. for Bantouyan
consumption. At this time, more shade Bantouyan transferred to
dryland farming can Yashe (cut to the side wings), and 2 January 2000
of the wild geese and chickens before one month, then of the wild
geese and into the water.

2. Stop illumination, expected to visit Green Bantouyan generally
begin in December at additional illumination to stimulate their
chickens, but that should stop illumination on the post-natal,
maternity or not allowed to prevent its spring. In addition, during
the off-off, to prevent Bantouyan obesity may be feeding material on
the Green, to save feed costs. Conditional arrangements should be
planted in the fall and pasture.

3. For each species, feed savings Use Bantouyan 3-6 month allowed
only in the annual, and other types of characteristics for the month,
when the last batch of eggs End of the wild geese and off, leaving
part of the high-yield, quality of the wild geese and, when all
commodities should Ngan sale. When the end of April last Xiaoyan
incubation loss, the selection of good Xiaoyan When growth of the
wild geese and retained for 9-10 months to 2 years just after the
spring, when these Bantouyan have sexual maturity and begin laying.
Xiaoyan from loss due to the hens used all succulence of the wild
geese and chickens used as fodder half, and therefore significantly
save feed.

4. Good health, vaccination Bantouyan although more
disease-resistant, little disease, but cats, serious environmental
pollution, immunity decline, coupled with cross-infection of poultry
to significantly increase the incidence and therefore should be
closed off to a vaccination. According to the main vaccination Yawen,
cholera two of Miao, E. vaccines several major vaccines. Ngan good
health care while also picked regularly disinfected. Using surface
culture, but also leave in the summer, and the removal of soil water
dung, reservoirs be disinfected.
