The goslings have a high metabolism and emit a large amount of carbon dioxide and feces. They produce harmful substances such as water vapor and ammonia. They need to be discharged in time to keep the air fresh. Otherwise, goslings can cause ammonia poisoning. To this end, it is necessary to strengthen ventilation in the brooding room. Ventilation should take place at noon on sunny days. Raise the room temperature by 1 to 2 and slowly open the doors and windows. Be careful not to blow the wind directly to the goslings to avoid cold.
The breeding density of goslings is closely related to the movement of the goslings, the air in the brood chamber, and the indoor temperature. Excessive breeding density is not conducive to growth and development, and is susceptible to bad habits such as feathering and toeing. When the density is too low, the utilization rate of the brooding room is reduced. The reasonable rearing density is: at the age of one week, 25 animals will be reared per square meter of area. With the growth of goslings, the stocking density will be continuously adjusted. By the first month of age, 4 to 5 animals per square meter will be raised. Geese hit the heap and die, pressure and conducive to the growth of the goslings are uniform and well-groomed. They should often be based on the size and development of the goslings, and should be grouped regularly according to the size and strength of the goslings. Generally, 50 to 100 animals per group are appropriate.
Hyaluronic Acid For Skin, Sodium Hyaluronate is well known as the best [Natural Moisturizing Factor". For Hyaluronic Acid Cream . In the early 1980s, the excellent moisturizing function of Sodium Hyaluronate has been widely concerned by international cosmetics industry. With its unique film-forming and hydrating characteristics, Hyaluronic Acid Powder Cosmetic Grade is used as a highly effective humectants in cosmetics. It attracts moisture to the skin and hold moisture in the skin, which preserve skin smoothness, suppleness and elasticity. 1 gram of Hyaluronic Acid Powder Cosmetic Grade is able to retain up to 1000 gram of water. So it is regarded as the [key to the fountain of youth".
The effects are as follows:
(1) Moisturizing effect
Moisturizing is the most important effect of Sodium Hyaluronate in cosmetics products. It can be hydrated shell
in skin surface and make the corneum hydration and softening. Compared with
other humectants, Sodium Hyaluronate is less effected by the environment as it
has the highest hygroscopic capacity in a relatively low humidity (e.g., in a
dry winter), but has the lowest hygroscopic capacity in a relatively high
humidity (e.g., in a damp summer). This unique property of Sodium Hyaluronate
makes the skin adapt to different seasons.
(2) Skin nutrition effect
Sodium Hyaluronate is the inherent biological materials of skin. The exogenous
Sodium Hyaluronate can complement the endogenous Sodium Hyaluronate. Low molecular Sodium Hyaluronate can
penetrate into dermis directly to improve the nutrient supply.
(3) Skin repair effect
There is some evidence that topically applied Sodium Hyaluronate can reduce
skin irritation
from various causes. During clinical trials it was also shown that this
ingredient is effective in promoting healing and fighting inflammatory
conditions of the skin. Sodium Hyaluronate serves as a free radical scavenger
and antioxidant, helping to protect the skin from the aging effects of
excessive sunlight exposure.
(4) Emollient and Film-forming
Sodium Hyaluronate is high polymer with high lubrication and film-forming.
Sodium Hyaluronate contained in cosmetics creates protective film on the
surface of skin, which retains moisture, and at the same time prevents moisture
in the skin from evaporation, so that improves freshness of the skin.
(5) Thickening
Sodium Hyaluronate solution have
high viscosity, and 1% solution is gelatinous. It can be added to cosmetics to
improve the thickening and stability.
