Nutritional characteristics of energy feed for pigs
Where the content of crude protein in feed dry matter is less than 20%, and the content of crude fiber is less than 18%, such as corn, wheat, millet, rice, broken rice, wheat bran, rice bran, etc., all belong to energy feed. (-) Corn soil rice has high energy, less fiber, good palatability and high digestibility.

The nature and application of feeding standard
(1) the scientific, practical and relatively reasonable feeding standards of animals are based on the theory of nutrition science and the results of production practice, and their indexes and values are obtained from a large number of scientific experiments, but they have been too extensive.

Matching principle of Pig Diet
The purpose of formulating the feeding standard is to carry out standardized feeding for pigs, that is, the diets used for feeding should be in line with the nutrition of specific pigs, and through the diet formula, pigs can be provided with nutritious full-price diets, give full play to the production potential of pigs, and improve feed utilization.

Processing and Storage methods of Pig Feed
Adopting appropriate methods to process and prepare the feed can increase the feed intake of pigs and increase the digestion and absorption of nutrients. First, the choice of feed raw materials can not be made into a good feed with comprehensive nutrition if there is a complete feed formula.

Key points of feeding and management of breeding boars
(1) the nutrition of breeding boars and the diets reasonably fed to breeding boars should pay attention to good palatability and should not be too large so as not to cause belly. The diet contains 12.9 megajoules of digestible energy, 17% protein, 7.9 grams of lysine, 2.6 grams of methionine and a moderate ratio of calcium to phosphorus.

Feeding and management of sows in the preparation period for breeding
1. Adopt short-term optimal feeding to restore the body condition of weaned sows as soon as possible. For the sows that began to be fed 3 days before weaning, the sows were not fed on the day of weaning, and the body condition of the sows was restored as soon as possible from the second day after weaning to mating, and the daily feed amount was increased to 2.5 kilograms after breeding.

Feeding and management of pregnant sows
The weight gain of sows in the early stage of pregnancy was faster than that in the later stage, accounting for most of the weight gain in the whole period, and most of the fat deposition was in this period. This shows that sows are mainly "re-fat" in the early stage of pregnancy, and the fetus in this period develops slowly, so a suitable low feeding standard should be adopted. but at this point,

Analysis of the causes of metaplasia, stillbirth and abortion in pregnant sows
The main results are as follows: 1. The causes of fetal transformation, stillbirth and abortion are as follows: (1) due to poor egg quality or failure to master timely mating, the egg ages prematurely, although it can avoid forced fertilization, but the embryo can not develop normally, resulting in death and absorption by sows. (2) the feed nutrition of pregnant sows is not comprehensive.

Feeding and management of parturient and lactating sows
(1) the superiority of net bed litter birth is a new technology rising in the intensive breeding field, which has the advantages of convenient work, dryness, hygiene, tread-proof, pressure-proof and so on. Compared with the ground birth bed, the net bed gives birth is to install the sow delivery room into a net bed and set up a fence to reduce the number of sows.

1. Strengthen the cleaning and disinfection of perinatal sows: one week before ① parturient sows enter the delivery room, clean and disinfect the delivery room, then wash the parturient sows one week before delivery, and then enter the delivery room after disinfection with compound aldehyde. ② washed the abdomen of sows with compound iodine solution 2 hours before delivery.

Feeding and management of suckling piglets
1. Physiological characteristics of suckling piglets after piglets left the mother, sudden changes took place in three aspects. ① piglets rely on maternal placental blood to supply oxygen and excrete carbon dioxide. After birth, they rely on their own respiratory system and blood circulatory system to supply oxygen.

Key points of feeding and Management of Piglet Conservation
(1) the feeding frequency, feed intake and feeding behavior of piglets with limited feeding in the early stage all affect the acidity in the digestive tract of piglets. The increase of pH value in digestive tract of piglets after feeding is related to food intake, so that multiple meals in piglets can slow down the acid requirement in digestive tract and make the pH value in digestive tract not.
