Headings: good time for the pig in the spring
The recovery of everything in the spring, at which time the temperature rises, is the season of producing and raising pigs and pigs, and is also a time of vulnerability to viruses and bacterial diseases. In the spring, where the temperature is so low and so cold, pigs are less able to adapt to changes in the spring because of their poor health and physical function, which affects their survival. In order to reduce the mortality rate of pigs in the spring and to improve the efficiency of pig farming, farmers should focus on several key points。
It's how we manage our first-born pig-rearing in spring
Prenatal disinfection and freezing. During the delivery period, pigs are required to clean, disinfect their breasts and nipples before delivery, as well as to quench, deliver beds and care boxes. On the day of delivery, sow feeding should be reduced or not fed to prevent over-eating from being detrimental to pig production. At the same time, various tools, such as iodine wine, scissors and ligatures, should be prepared for delivery with care to decontaminate a certain concentration of iodine-voltage solution in the larvae wound and to ensure normal breathing by removing the slime from the mouth and nose of the pig. In winter and spring, before a child is born, the temperature of the box must be between 30 and 32°c to ensure that the pig can be in a comfortable environment. In addition, there is a need to keep warm during the production process and to create a warm and comfortable production environment for pigs。
When a pig is born, keep it warm and warm. There is a clear difference in the appropriate temperature of new-born pigs of different ages: 30 - 32°c at the age of 1-3 days, 28 - 30°c at the age of 4-7 days, 25 - 28°c at the age of 8 - 14 days, 22 - 25°c at the age of 15 - 30 days and at the temperature of the partition from the age of 31 days to 22°c。
I'll fix my nipples, eat my first nipples and make up for it. Since primary breast milk contains antibodies and nutritional factors produced by the mother, it has many effects on the growth and development of piglets, and for those who are weak and unable to breastfeed, it is necessary to help other piglets to breastfeed by artificially assisted means after they have finished, in order to enhance their nutrition and help them to replenish their water and antibodies. The general operation of fixing nipples is to allow piglets to choose their own nipples and then adjust them to their weight sizes, so that some weak piglets can properly be placed in front of them, because the front nipples contain more milk, while some big piglets can be placed behind them to ensure that each piglet receives adequate nutrition and antibodies. In general, during a six-month-long drink of pig milk, piglings start feeding some of the feed and lead them to eat with the sow, which is also intended to enable piglets to adapt to feed eating habits in the future。
Watching changes in pigs and pigs, it was observed that conditions needed to be quarantined and treated in a timely manner. Newly born pigs are highly vulnerable to cold or bacterial and viral infections, and this phase requires the care of their breeders to carefully observe their growth and food status, and can be appropriately supplemented with some good feed for thin pigs. If food problems with pigs are detected, specialized veterinary doctors are required to examine them in a timely manner and to treat the disease in a timely manner to prevent the occurrence of cross-infection if it is diagnosed. At the same time, each feeding must be done with the care of the pig so as to prevent the case of the strangulation and even the death of the pig while she is lying down。
Do your best to get rid of the virus. In the spring, various viruses and bacteria are widely spread, and a certain dose of vaccination against the disease can be given to pigs in advance for their vaccination purposes, usually in groups around the third day of their birth。
Do the weaning job. Piglet is usually able to wean off after the full month, but must be able to do so flexibly, taking into account the actual situation of the pig, e. G., food, climate, material type, etc., and depending on the mother's milk situation, if she is fed earlier, she can be weaned early at the age of 28 days. It is important to note that during the peak of the mother's milk, weaning is not necessary during an outbreak, and that if the pig is in serious condition, she needs to be weaned in a timely manner. The gradual improvement of future feed, environment and management on the basis of the mother-to-child weaning method, which ensures that there is no change in feed, environment, management and prevention of stress in pigs, ensures that pigs and pigs are able to adapt。
The reason why weight difference is obvious
Reasons for differences in weight when weaning a pig
It's different blood. In the case of incendiary hogs, artificial infusion is carried out in the form of double-coupling, i. E., 12 hours after the first hogs are sown and recombined with another hog. The same type of father is not the result of the production of co-convene pigs, whose genetic differences lead to different rates of growth and weight。
The embryo is in different positions. Although born to the same mother, the different position of the embryo in the womb leads to different growth and development. At the end of the uterus, differences in the availability of nutrition result in different development and hence different birth weight。
Lactating nipples are different. Upon birth, a strong pig takes advantage of the pre-front and mid-generous nipples, which are well nourished, while a weak pig eats milk before and after the mid-milk, which is not sufficient for nutritional needs and slows growth。
Breastfeeding has occurred. Indigestion can affect nutritional absorption if it occurs during breastfeeding, but can still lead to slow growth despite cure. Diseases such as infectious gastrointestinal infections, yellow, white diarrhea, chronic respiratory infections (local asthma)。
Reasons for differences in the weight of the same-weight pig at the same time
The difference in origin. The patrilineal and matrilineal genetic factors of different varieties influence the speed of weighting of pigs. In the case of pigs with local north-east pig blood, the growth rate is slower than that of exotic hybrids; in some cases, the pigs have had diseases that affect growth prior to their purchase or have had healthy virulent pigs, such as yellow, white diarrhea and hidden periods of local asthma; the weight gain is faster than that of the mother because of certain differences in the weight of the male and mother as a result of biological properties; the age at which the food start-up training takes place is earlier, the quality of the product is better adapted and digestive and the rate of growth is faster; and the individual growth is differentiated by the genes。
Differences in breeding processes. In the process of breeding, there is a phenomenon of bullying, which results in less healthy, less well-fed and slower growth of the same pig, and faster growth when the stronger the more he eats, and when he is bought, he recovers from a hidden disease or illness, which affects growth rates such as local asthma, digestive parasites and chronic pig plagues。
Differences in fertility methods. There's a difference in weight speed between the movement and the incompetent pig. There is a difference between the sexuality and appetite of an incompetent pig in the process of fertilizing, leading to a difference in weight, which tends to grow faster than it does; there is also a difference in the rate of growth of a young pig who is born with a cut tooth, a broken tail and a non-cut tail, which is slightly faster than that of a broken pig。
The profit factor plus the price of the pig and the pig
As a result of central storage efforts, the “recovery” of both raw and pig prices was earlier this year than last year。
In the first week of march, the market price for the collection of pigs in the weihai district of shandong province was $39/kg. Since its entry into february, the prices of pigs and pigs have been increasing exponentially, with the prices of pigs collected in the first, second, third and fourth quarters of the region increasing by 34. 6 per cent, 42. 3 per cent, 52 per cent and 56 per cent, respectively, in the first, second, third and fourth quarters of february, well above the prices of raw pigs in the same period。
The main reasons behind the increase in the price of pigs are as follows:
One year is the spring, which is the best time for the traditional refilling of pigs. Every year after the spring season, places are at the peak of the refilling column, which has been affected earlier this year by the market, resulting in increased demand for pigs。
There was a strain on the supply of the pig market. Market research has found that the supply of pigs is mostly low in the years to come as a result of, inter alia, the winter epidemic, that the current period is characterized by a high incidence of market epidemics and that conventional diseases such as blue ears and diarrhoea have a greater impact on pigs, resulting in the death of some of them, and that the lack of seedlings in some areas is one of the reasons for the increase in the price of pigs。
The farming end looks at post-market pig prices, the economy after that
There has been a gradual recovery in consumption, which is expected to improve markedly in 2023 compared to 2022. Thus, it was agreed that the price of pigs in the second half of the year was on a warming trend, with a marked increase in second-generation fertilizer and the heat of the pig's supplement, leading to a chain increase in the price of pigs。
The price of raw pigs led to a “reversible rise” in the market as a whole in february, coupled with a central reserve policy to the city, further boosted the incentives of farmers。
Multiple good-interest factors have contributed to successive increases in the price of pigs and pigs, and it is expected that the subsequent high rates will continue. However, current farming costs are still high, and it is recommended that farming households view the behaviour rationally and account for the meat ratio of the pig farm according to their own circumstances, and make the additions as appropriate, so as not to be blind。
