First, feeding and management 1. Enclosure environment: clean, dry, dust-free, temperature is suitable for 18-25 degrees Celsius, moderate density (3 heads/M2), good ventilation (no thirsty wind), adequate lighting. 2. Tuning: Piglets should be strengthened in feeding and management within a week of purchase, so that pigs can develop good habits of eating, sleeping, and excreting, which will facilitate future management and reduce labor. 3. Feeding: 30 pounds of body weight or less, can be fed 5 times a day, the time interval should be the same for each feeding, can be fed suckling pig or use SL221 ingredients. 30 pounds -60 pounds of body weight are fed four times a day, using S512 ingredients. 60 pounds - slaughtered, feed 2-3 times a day, using S513 ingredients. The daily feed intake is calculated as: Weight less than 30 pounds = Weight = 0.05 pounds. 30-100 pounds = weight * 0.045 pounds. 100-160 kg = weight * 0.04. 160 - slaughter = weight * 0.035. Based on the above formula, the calculated daily feed intake can be reduced in summer and autumn, and it can be increased in winter and spring. (except for free intake) 4. Drinking water: The daily water intake of a pig is about 2 times the daily intake, and it can be increased in an appropriate amount during the hot season. Therefore, sufficient and clean drinking water must be given. 5. Castration: The piglet castration can be implemented during the second week of the purchase and when it is fasted in the morning, it must be done when the piglet is in a good state of mind, healthy and disease-free. Before filling, add water to the water or feed. 800 kg of water or 400 kg of spices are used together for 7-15 days to reduce the pig's stress. 6. Disinfection: A, environmental disinfection, disinfection usually 1-2 times a week in the summer, 3-4 times a week in winter, disinfection once a day in the disease-prone season (with pig disinfection) can choose to use Wei Kang, special kill or farm blessing Use in turn to avoid virus and bacterial resistance. B, disinfection of drinking water, every three days plus three days Wei Kang or potassium permanganate, can also be used Xin Kang Kang or Keduening (200-400 kg per bag of water) Second, disease prevention and control 1. Piglets were immediately injected with swine fever vaccine when they were purchased. Each piglet was injected with 6-8 piglets and 1-3 ml of Delixian was injected at the same time. Other vaccines can be used to develop a reasonable immunization schedule according to the season and local disease epidemic. All kinds of bacterins do not do as little or as little as possible, through careful management, regular administration of drugs to prevent bacterial diseases; strengthen disinfection. Piglets allergic to the vaccine can be treated with 2 ml of epinephrine or dexamethasone. 2. After 2 hours of water supply to the piglets, the piglets should be given less ground, avoiding stress diarrhea, accelerating the water intake in the water, and even drinking for a week, drinking better in the long term. Can improve the disease resistance of pigs. Promote growth and development of piglets. After four hours of purchase, feed (appropriate amount of material in the first three days before purchase, and feed six or seven full meals per day). Adding Hushushu or Hunuoyu (100g per 100 kg of feed plus feed) for a week, Control common bacterial diseases. 3. When the piglets purchase the second week of deworming, they can add Dinobi (50g per 100 pounds of feed) into the feed and feed it for a week to remove various parasites inside and outside the pig. When it is purchased two months later, the pig will no longer be disturbed by parasites when it is slaughtered. 4. When the piglet is purchased for the second month, another week of Hunobi is added to the feed. Before the weight of 80 and 130 pounds, the feed is supplemented with Taishuping (80g per 100 pounds of feed) or oxytetracycline for one week. Salt (mixed 200 kg of feed in each bag) controls various respiratory diseases. (Liaoning company Qiu Baoku)
Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages, and on hydrolysis give the constituent monosaccharides or oligosaccharides. They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch and glycogen, and structural polysaccharides such as cellulose and chitin.
Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure, these macromolecules can have distinct properties from their monosaccharide building blocks. They may be amorphous or even insoluble in water. When all the monosaccharides in a polysaccharide are the same type, the polysaccharide is called a homopolysaccharide or homoglycan, but when more than one type of monosaccharide is present they are called heteropolysaccharides or heteroglycans.
Natural saccharides are generally of simple carbohydrates called monosaccharides with general formula (CH2O)n where n is three or more. Examples of monosaccharides are glucose, fructose, and glyceraldehyde. Polysaccharides, meanwhile, have a general formula of Cx(H2O)y where x is usually a large number between 200 and 2500. When the repeating units in the polymer backbone are six-carbon monosaccharides, as is often the case, the general formula simplifies to (C6H10O5)n, where typically 40≤n≤3000.
As a rule of thumb, polysaccharides contain more than ten monosaccharide units, whereas oligosaccharides contain three to ten monosaccharide units; but the precise cutoff varies somewhat according to convention. Polysaccharides are an important class of biological polymers. Their function in living organisms is usually either structure- or storage-related. Starch (a polymer of glucose) is used as a storage polysaccharide in plants, being found in the form of both amylose and the branched amylopectin. In animals, the structurally similar glucose polymer is the more densely branched glycogen, sometimes called "animal starch". Glycogen's properties allow it to be metabolized more quickly, which suits the active lives of moving animals.
Cellulose and chitin are examples of structural polysaccharides. Cellulose is used in the cell walls of plants and other organisms, and is said to be the most abundant organic molecule on Earth.It has many uses such as a significant role in the paper and textile industries, and is used as a feedstock for the production of rayon (via the viscose process), cellulose acetate, celluloid, and nitrocellulose. Chitin has a similar structure, but has nitrogen-containing side branches, increasing its strength. It is found in arthropod exoskeletons and in the cell walls of some fungi. It also has multiple uses, including surgical threads. Polysaccharides also include callose or laminarin, chrysolaminarin, xylan, arabinoxylan, mannan, fucoidan and galactomannan.
