Feed Formulas and Scientific Preparation Methods for Lactating Sows
Lactating sows need large amounts of nutrients to support lactation. During peak lactation, the sow's milking capacity exceeds the nutrients she takes in through feed and exceeds the nutrients excreted in milk, so her body condition declines rapidly. Preparing high-quality, high-nutrient-density feed for lactating sows is the best way to resolve this contradiction. Feed Formula 1: Lactation Feed Formula 1 in Table 4-3 avoids as much as possible the use of bulky feeds such as alfalfa and rice hull bran. In the design of lactation feed formulas, unknown nutritional factors appear to be less

Application Methods of Fertilizer Long in Formula Fertilization for Rice
1. Advantages of Fertilizer Long: (1) Long-acting and synergistic effect, extending the fertilizer efficiency period of nitrogen fertilizer by 1 time, with no fertilizer deficiency phenomenon throughout the entire growth period of rice. (2) Improved nitrogen fertilizer utilization rate; deep fertilization overcomes fertilizer loss due to running, overflowing and seepage of field water, reducing fertilizer loss. (3) Enhanced resistance of rice to low temperature, drought and disease erosion. (4) Changes traditional multiple surface fertilization to deep one-time fertilization, saving fertilization labor and costs. (5) Reduced nitrogen fertilizer dosage; according to plots with different fertility, the pure nutrient amount of nitrogen fertilizer can be reduced by 15%-25%. 2. Fertilizer Long

How to treat postpartum paralysis in pigs and sheep? This effective formula works well
1. Treating postpartum paralysis in sows. Postpartum paralysis in sows mostly occurs within 2-5 days after farrowing. In the early stage of the disease, the animal is listless, has reduced appetite, and produces less milk; body temperature is normal or slightly elevated. In mild cases, standing is difficult and the hindquarters sway; in typical cases, the animal cannot stand and lies down in a stupor. For treatment, add 4% bone meal, AD3 powder and trace element additives to the feed. Inject the sick pig intramuscularly with 3-5 milliliters of vitamin D3 colloidal calcium, 5-10 milliliters of vitamin E injection (twice daily); vitamin D3 600-1200 international units, once daily, or take an appropriate amount of quicklime, add clean water, stir and let stand. Each time the affected sow is fed, take 300-400 milliliters of the clear supernatant limewater and mix it into the feed. Generally, feeding continuously for 10 days gives a marked curative effect.

How to mix nutritional formulas for silkworms in summer and autumn
The main feed for silkworms is mulberry leaves. Since the quality of mulberry leaves varies greatly between seasons, it has a considerable impact on cocoon yield and quality. If nutritional supplements are fed to silkworms raised in summer and autumn, the yield can increase by 10%-20%. The formula techniques are introduced as follows: 1. Supplement formulas and feeding methods. 1. Glucose solution additive. During the silkworm rearing period, if there is continuous rainy weather, the mulberry leaves are tender in texture due to insufficient sunlight, have a high moisture content, and lower carbohydrates. At this time, a 5% glucose solution can be sprayed on the harvested mulberry leaves. After

High-nutrition formula cultivation of oyster mushrooms can achieve exceptionally high yields
The high-nutrition, exceptionally high-yield cultivation technique for oyster mushrooms uses raw materials such as wheat straw and rice straw, and adopts measures including high-nutrition formulas, removing the plastic casing from the mushroom logs, and covering with nutrient soil, so that the input-to-output ratio reaches more than 1:10, with very significant economic benefits. 1. Strain selection: choose wide-temperature varieties such as Changbai No. 1. The suitable cultivation time is from September of the current year to April of the following year. 2. Formula and treatment: there are 4 formulas: ① 50% soybean straw (crushed), 40% corncob or wheat straw, 8% cornmeal or wheat bran, 2% lime. ② 70% wheat straw, 27% wheat bran, 1% compound fertilizer

How to apply formula fertilizer to garlic to save fertilizer and increase income
In 2005, 8 demonstration sites were set up in the three towns of Wangmiao, Yucheng and Lige and in Luotun Township, with 100-130kg of formula fertilizer applied per mu, averaging 121.9kg per mu (equivalent to N 17.1kg, P2O5 21.9kg, K2O 12.2kg), while a conventional fertilization control was also arranged, with an average of 129.4kg of compound fertilizer applied per mu (equivalent to N 20.7kg, P2O5 20.7kg, K2O 20.7kg,). At harvest, 5 sites were actually harvested and 3 sites were yield-measured, and the average yield per mu in the formula fertilizer demonstration area was 1485.

Reasonable pig feed formulation is the only way to prevent pigs from losing their appetite
When the temperature rises above 35°C, pigs have low feed utilization and slow weight gain. Therefore, in hot seasons, different feeding methods should be given according to different categories of pigs and different physiological stages of pigs. Boars: feed 2 times a day, and add green feed or thin feed at noon. Mating and exercise are both carried out in the morning and evening; after mating, do not immediately let them go into water to wallow or spray them with cold water. From 1 p.m. to 3 p.m. every day, spray water once on the pigs' bodies and the ground, and reduce light to 8-10 hours. If the number of matings is low, the amount of concentrated feed should be reduced to prevent overfattening and poor libido.
