Reference should be made to the pig's various feed standard tables based on the reference feeding standards and flexibly applied based on the pig's growth and production performance in practice. If the nutrient level of the compound feed is found to be high, it may be reduced to some extent; otherwise, it may be increased appropriately.
Pay attention to palatability It is generally believed that foods that are rich in water and foods rich in sugar, oil, or protein have good palatability, and poor palatability in dry, fibrous, or bitter. Pigs like to eat a good green feed with a sweet, sour or rich aroma. Pigs have a keen sense of smell and taste and sometimes refuse to feed if they are fed different feeds than usual. Therefore, it is necessary to incorporate some of the pig's favorite old feeds to adapt them gradually.
The choice of ingredients should be as good as possible and inexpensive to use nutritious and inexpensive feeds to match, in order to reduce pig feed costs and improve pig production efficiency. At the same time, according to local conditions, the use of feed in time and make full use of local feed resources.
Considering the physiological characteristics of pigs, different types of pigs have different differences in the absorption and utilization of feeds. Although compound feeds are stipulated in accordance with the feed standards, the type of feeds should be selected for differentiation. For example, for growing pigs, it is not appropriate to use fiber-rich feeds. In particular, piglets cannot use feeds with poor nutrition and bulk, otherwise they are not digestible and they also reduce the growth rate.
Considering the relationship between feed supply and pig feed intake The feed supply must be compatible with the volume of the gastrointestinal tract of the pig and its ability to digest and absorb nutrients. Too much feeding will increase the gastrointestinal burden of the pigs; too little feeding will lead to insufficient nutrition of the pigs, which will affect the growth. The amount of feed the pig can feed depends on the amount, quality, and number of feed dry matter.
The type of feed should be diversified to increase the type of feed, so that the pig can get a full nutrition without partial eclipse, maintain health, and promote growth.
Consider the impact of feed on pork quality. Feed has a greater impact on pork quality, especially fat. Feeding linseed and its by-products will produce soft fat, while feeding carbohydrate feeds will produce hard fat. There are also some feeds that can pass their special odors into the fat and meat of the pigs. If the pigs in front of the column are given fishmeal containing a lot of fat, the quality of the pork will be reduced.
Considering the impact of feed on health, it is necessary to match light-discharge and constipation feeds. In the feeding of fermented roughage, starch-based concentrates that promote fermentation are reduced.
Adding a dry feed with succulent feed alone can cause pigs to lose appetite. In winter, when the temperature is low and the pigs drink less water, it is necessary to feed more fresh roots and silage to achieve the purpose of rehydration.
With wide experience and expertise, Hi-Tech Co., one of the professional manufacturers and suppliers in China, warmly welcomes you to buy or wholesale our quality, safe and effective manufacturer Hyaluronic Acid Powder sodium hyaluronate, professional made in our factory.
We can supply 4 grades Hyaluronic acid: Food grade Hyaluronic acid, Cosmetic grade Hyaluronic acid, Eye drop grade Hyaluronic acid, injection grade Hyaluronic acid.
Hyaluronic acid is a high molecular weight polysaccharide with D- glucuronic acid and N-acetyl-glucosamine as repeating structure unit. Because of the action of hydrogen bond between the monosaccharide in HA linear axle, HA molecular forms a rigid screw column structure in space. Strong hydrophilic properties exist due to the large amount of hydroxyl groups. Furthermore, HA has a special water binding function and binds its water very strongly, so that it has strong water retention. Theoretically its binding water capacity is up to 500 ml/g as an ideal natural moisturizing factor.
HA is also one important component of the skin. It can prevent skin from aging
and improve the appearance and tactile sensation of skin.
A part of low molecular weight HA can penetrate into dermal layer to control
the mid-metabolism, and make the skin moist, smooth and elastic. Therefore the
cosmetic functions of HA are its resistance against skin wrinkles and its
general health protection. HA is not only a good skin moisturizer, but also
promotes cell' s metabolism of skin. So HA stands for bio-mimetic cosmetics.
Hyaluronic acid is a natural part of the human body why it is highly suitable for many applications within the field of medicine and related aids. It is used in ophthalmology, orthopedics and cosmetic surgery. With the researching and development of application in medicine area, hyaluronic acid`s application as HA-supplementation and medical treatment material will be one major stream in health care Industry.
