Piglet "four segments" efficient feeding management measures
The arrangement of piglets' nutrition and feeding stages is closely related to factors such as weaning age, weaning weight, barn setting, and arranging arrangements.
One and one stage feeding mode
It should be said that the earliest domestic promotion of feed is actually a one-stage rearing mode. At that time, most of the pigs were three-dollar Duchangben/Dubenben, weaned at about 45 days of age, and converted to small ones at 70 days of age. Pig material. At the current production level, 60-day-old pigs weighed 15 kilograms, the best ones were able to reach 19-20 kilograms (small groups), and sows had an average of 2 fetuses per year, and the entire group had a ratio of 4:1.
The current general-purpose sucker feed or some low-end feeds for pigs are more suitable for the one-stage model and are suitable for pigs that have been weaned late and have a general variety. (Better pigs tend to be weaned if they are weaned too late. Emotional phenomenon) The advantage of this model is that the feeding is simple and convenient and the cost is low. Its disadvantage is that the piglet production potential has not been fully realized.
Second and second stage feeding mode
With improved sow breed and hybridization, foreign pig breeds and crossbreeding pigs have become the main species for large-scale farming. Early weaning of piglets (reducing sow omnivorousness and promoting healthy growth of piglets) becomes an inevitable requirement.
The original first-stage feed can not meet the growth needs of piglets, especially when the piglets' weaning days are advanced. It is very important to transition from mother milk to feed. On the basis of the original phase of the piglet feed, the company introduced specialised chute products for nutrient concentration, palatability and digestibility, etc. to meet the needs of the piglets and weaning needs. At the age of 45 days, a nursery-stage special-purpose feed product, the nursery stock, was introduced in order to ensure the health and rapid growth of the herd. It is used from the age of 45 to 70 days.
Three and three stage feeding mode
This model is to solve the problem of growth stagnation of weaned piglets, low survival rate of nursery pigs and high proportion of dead pigs.
Piglets have the potential for rapid growth, but because of various factors, the growth potential of more than 75% of piglets does not come into play. To further advance the age of weaning piglets, and to better prevent negative growth and stagnation of weaned piglets after weaning, and to solve the immunosuppressive problems such as PRRS and circovirus disease, which will facilitate the conservation of nursery pigs. The two-stage feeding mode was improved, and a new three-stage feeding mode was introduced (chap feed + pre-care feed + post-conservatory feed).
The further upgrade of the chute material satisfies the nutritional needs of piglets at early weaning, which results in higher nutrient concentration, better digestibility, better palatability, and better resistance to diarrhea in the actual breeding work. With the ease of teaching and the goal of easy weaning, piglets gain more than 300 grams of daily weight within 10 days of weaning. The chute material is used between the ages of 21-25 days weaning to 35 days of age, with a dosage of about 4 kilograms. The weight of the piglets can reach 9.5-10.5 kilograms at 35 days of age.
The evaluation of the quality of teaching materials is not based on the nutrition index. The key is the palatability, feed intake, digestibility, anti-rare-digestion capacity. Whether the piglets can achieve Wangshi food within 3 days after weaning, if the cumulative intake exceeds 600 grams is the judging standard for the top cutting chute material at present. "Weaning for 3 days" is the reason. When the difference in daily gain of piglets within 50 days of weaning is 50 grams, the feed product price can differ by at least 2000-2500 yuan/ton.
In the aspect of nursery materials, the feed in the nursery period was optimized, and the pre-conservation materials were specifically introduced. The age of use was also advanced to 35-42 days of age. The pre-care period was a delicate stage in the pig growth process.
At this stage, we must first achieve a transformation in nutrition. We must transition from the highly nutritious, high-digestibility, and high palatability curative materials to the preservation of feedstuff products made from conventional materials such as corn and soybean meal to avoid secondary nutrient stress. .
Secondly, the pre-conservation period is also a period of high incidence of epidemics. As the piglets are in the empty window of immunity before and after weaning, the body's resistance is low, resulting in the proliferation of pathogenic microorganisms in the body. When the pre-care period, the piglets often begin to show clinical symptoms.
Third, in the early stages of childcare, the stress caused by using multiple vaccines is a great challenge to the health and growth of piglets. Feeding specialized nursery pre-feeding materials, in addition to providing highly nutritious and high digestible feeds, can also promote the improvement of the body's immunity, reduce the incidence of respiratory and digestive tract diseases in piglets, reduce various immune stresses, and effectively improve conservation. The health condition of the pigs in the previous period is conducive to the growth of the pigs. The use period of pre-care materials is from 35-42 days old to 49-56 days old.
This model is also the most classic model used in many pig farms.
Fourth and fourth stage feeding mode
On behalf of the mother's milk + teaching material + pre-care material + nursery material.
The four-stage model is mainly applicable to some ultra-early weaned pig farms, especially for pigs that have been isolated and weaned in order to purify specific diseases. Of course, they can also be used for the treatment of non-dairy or abnormal suckling pigs. The main difference between this model and the three-stage feeding model is the addition of a first-stage material similar to the surrogate mother's milk.
