Formula and application of feed for piglet

Teaching trough feed is not only a feed product of suckling pig stage, but also a special feed product with high nutrition from birth to 4 weeks old. The main types of teaching trough material used in production are granule, crushing, powder and liquid. The first three are the most widely used in actual production. Let's take a look at the formula and use of suckling pig trough material.

The formula of teaching trough material for suckling pigs

1. Feed formula: expanded corn 300.00 (kg), corn (grade I) 263.00 (kg), full-fat soybean 125.00 (kg) whey powder 3120.00 (kg), peeled soybean meal 3120.00 (kg), plasma protein powder 3120.00 (kg), imported fish meal 50.00 (kg), soybean oil 20.00 (kg), calcium dihydrogen phosphate 4.00 (kg), calcium powder 6.00 (kg), Acidifier 3.00 (kg), sodium butyrate 1.00 (kg), zinc oxide 3.00 (kg), lysine 3.00 (kg), methionine 1.00 (kg), threonine 1.00 (kg), premix 10.0 (kg).

2. Nutritional indicators: digestible energy 3500 kcal / kg, crude protein 18.0%, calcium 0.65%, available phosphorus 0.45%, lysine 1.40%, methionine 0.45%, threonine 0.91%, tryptophan 0.24%.

Characteristics of trough feed for suckling pigs

1. Easy to absorb: suckling pig trough feed contains low content of anti-nutritional factors and allergic factors, and improving feed digestibility is the key to increase feed intake of suckling pigs. The feed has a good performance after digestion, absorption and re-deposition, and the daily weight gain of suckling pigs at this stage is of special significance to the whole growth performance of commercial pigs.

2. Good palatability: suckling pigs like to eat, feed intake is very large, it is possible to have a good daily gain index.

3. Nutrition balance: the nutrient composition of all kinds of raw materials is different, and the digestibility is also different. Therefore, it must be scientifically formulated and carefully prepared.

4. Low incidence: in particular, it is necessary to minimize the incidence of diarrhea. The indigestible feed enters the large intestine after passing through the small intestine, which is a good medium for bacteria in the large intestine, which leads to the rapid reproduction of bacteria in the large intestine, which is the main cause of diarrhea in suckling pigs.

5. Weaning stress: weaning stress will result in weight loss and growth stagnation of piglets after weaning. In order to restore the normal growth rate of pigs as soon as possible and make up for the stress loss of weaning, it must be solved by increasing the feed of weaned pigs and improving the feeding conditions.

The use of trough material for suckling pigs

The main results are as follows: 1. The use time of the teaching trough material is arranged from 7 days after birth to 14 body weight after weaning, a small amount of food is fed every day from 7 to 14 days after weaning, and 4 times per day from 14 to 5 times a day before weaning. Through these two stages to ensure the success of the piglet trough, 10-14 days after weaning gradually transition to conservation material.

2. Usage: free feeding and step-by-step feeding are two main methods to use teaching trough materials.

① free feeding: free feeding is to add a sufficient amount of feed regularly, and remove the residual contaminated feed in time each time.

② feeding: feeding is 4-6 meals a day, so as to feed less frequently. When feeding the teaching trough material in the early stage, you can feed a few granules when injecting a health care needle or epidemic prevention needle, or paste it on the sow's nipple to allow the piglets to eat when they are breast-feeding, or adjust the proportion of water feed at 4:1 into a paste, or give the piglets a little granule to stop for a while before breast-feeding.

3. Precautions: the bag feed should be fastened in time after opening and collecting materials, and the shelf life is generally 45-60 days to prevent deterioration due to moisture absorption. Maintain the material trough and environmental hygiene to prevent feed pollution. When feeding, make sure that piglets can drink clean water. Feed less and add more frequently, and gradually overfeed. Pay attention to keep the piglets warm.
