Comprehensive measures to improve the body weight of weaned pigs
If the piglets are weaned at the same age, the greater the individual weight of weaned piglets, the stronger their physique, the stronger the vitality of piglets, the faster the weight gain after weaning, the higher the feed conversion rate and the higher economic benefits. Therefore, taking comprehensive measures to strive for the maximum individual weight of weaned piglets has become one of the keys to improve the economic benefits of raising pigs. 1. Long sows were selected and crossbred to improve the birth weight of piglets. The birth weight of piglets determines the strength and increase of piglets' vitality to a certain extent.

Breeds and characteristics of ducks

Representative are Beijing duck, Cherry Valley duck, French Muscovy duck, Oberstar duck and so on. At present, French muscovy duck and Oberstar duck are more suitable for the market, which are characterized by good meat quality, high lean meat rate, low feed-to-meat ratio and strong disease resistance. For example, the meat of French Muscovy duck has the flavor of wild fowl; chest and leg muscles account for 27% of the carcass;

Three attentions in feeding self-made Pig Feed
Whether it is family or intensive pig raising, using self-made pig feed can greatly reduce the feeding cost. However, three "precautions" must be grasped when feeding self-made pig feed. Pay attention to the type and proportion of raw materials commonly used pig feed raw material proportion is: grain such as corn, rice, barley, sorghum, etc., generally should account for 50%-70%; bran such as wheat bran, rice bran, etc., generally should account for 10%-20%; toxic cottonseed cake, meal and rapeseed cake, etc., should be less than 10%.

Prevention and treatment of Porcine Respiratory Syndrome
With regard to the situation that the respiratory disease of growing and fattening pigs in Luxi pig farm is more serious than that of fattening pigs, a lot of drugs have been used to control it without good results, that is, as farmers say, "good money has been spent but no good has been done." Since 2005, many piglets in pig farms have developed pneumonia, cough and cyanosis in individual pigs' ears. Growing pigs weighing more than 25 kg are mainly characterized by cough and wheezing as well as dermatitis. Compared with 2005, diarrhea is the main symptom, but now it is mainly respiratory symptoms and cough and fecal spray. Hot climate in summer and autumn

Identification of the best insemination time of sows by hand pressure method
The insemination worker stood on one side of the estrus sow, facing the sow's back, stretching both hands flat, gently on the sow's back, and then gradually exerting pressure, if the sow's back suddenly bowed up and had a sense of upward rebound, and then pressed for 1-2 minutes, the sow stood still and kept barking, it was the best time for insemination; if the sow's limbs moved back and forth, accompanied by a cry, it was not the best time for insemination.

Effect of Air flow on Pig growth
The effect of air flow on pig body is mainly to affect the heat dissipation of pig body. Under general environmental conditions, as long as there is air flow, it can promote the convection and evaporation heat dissipation of the body. When the ambient temperature is lower than the suitable temperature limit of the pig, the heat dissipation of the pig is increased due to the action of air flow, which makes the pig feel cold. at this time, more energy is needed to maintain the body temperature. On the contrary, when the ambient temperature is higher than the upper limit of the suitable temperature for pigs, because the air flow contributes to the heat dissipation of pigs, and when the air flow is large, the heat dissipation is more, so the wind speed is increased.

How to rescue pig poisoning
The causes of pig poisoning are feed poisoning and drug poisoning. There are five common rescue methods: vomiting is generally used for organophosphorus and other drug poisoning. Can be subcutaneously injected with veratrine 0.01g to 0.03g, or oral emetic agent 1g to 3g (or potassium antimony tartrate 1g to 2g); if there is no emetic, you can also use sticks and hoses to gently wipe the throat mucosa to cause vomiting. Gastric lavage should be carried out 4 or 6 hours after the poison enters the pig. Hydrocyanic acid poisoning can be selected 1

Etiological Analysis and differential diagnosis of Chicken leg Diseases
In the process of feeding, chickens often suffer from leg diseases such as soft feet, claudication, paralysis, squatting and unwilling to walk, deformed legs and paws and paralysis. The causes of leg diseases in chickens are extremely complicated. Leg disease is mostly a symptom of a disease, or a type of disease, a very small number of independent diseases, which some people call foot weakness syndrome. The occurrence of leg disease in the flock directly affects the uniformity of the flock and improves the abandonment rate and sporadic mortality of the flock. In this paper, the etiology and characteristics of chicken leg disease are summarized as follows. Chicken leg

How to prevent swine dysentery
Porcine dysentery is an acute infectious disease caused by Treponema pullorum, which is characterized by varying degrees of mucinous hemorrhagic dysentery (commonly known as "blood dysentery"), weight loss and catarrhal hemorrhagic and necrotizing inflammation of the cecum. The disease can occur all the year round, and can occur in pigs of all ages, mostly at the age of 2-3 months. The morbidity of piglets after infection can reach 75%, and the mortality rate is 5% 25%. Diseased pigs and infected pigs are the main sources of infection, and fecal pollution is the main route of transmission. The carrier rate of recovered pigs is very high.

Pig poisoning is mostly caused by feeding half-cooked food
Some farmers feed pigs with half-cooked food, and soon after eating, pigs will be manic, walking, breathing difficulties, convulsions and death. This is food poisoning, the main reasons are as follows: first, vegetables will be placed in the pot for a long time slow cooking, coupled with no stir, easy to produce a toxic substance called hydrogen cyanide, pig food after easy poisoning. Second, the feed is not cooked cooked thoroughly, long-term storage deterioration. When pig food is around 40 ° C ~70 ° C, it will be stuffy in the pot for a long time, and the nitrate in the feed will be converted into a nitrite.

Attach importance to the rational drinking water of pigs
First, the harm of insufficient drinking water of pigs is widespread in pig feeding, which only pays attention to feeding while neglecting drinking water, but they do not realize that drinking water and feeding are as important as feeding, even more important than feeding. The main harm of insufficient drinking water is: 1. Insufficient drinking water will lead to an increase in the incidence of intestinal tract in pigs. Farmers raise pigs, most of them use the traditional one-time feeding method of water supply, no matter what the weather conditions, regardless of the type of feed, do not give drinking water. Pigs often drink dirty water after they are thirsty due to lack of drinking water, especially in hot summer.

An overview of proteins in the nutritional needs of pigs
(a) carbohydrates are the most widely sourced and account for the largest proportion of nutrients in diets, and are the main source of energy for pigs. In cereal feed, there is little soluble grass sugar and disaccharide, mainly starch, so it is the main energy source of pigs. Starch is converted into glucose by amylase in the digestive tract and then absorbed into the blood to form blood sugar. Biooxidation and energy supply in the body. The digestibility of soluble sugar and starch in livestock is 95% to 100%. In piglets before 3 weeks of age, due to the secretion of pancreas in the digestive tract.
