How to increase sow farrowing rate?

To improve sow reproductive performance and increase litter size, it's essential to focus on proper feeding and management throughout the entire breeding cycle. First, during the non-pregnant period, sows should be given a diet rich in green and juicy feeds to maintain a good body condition. This helps ensure they are in optimal health for breeding. Second, before mating, sows should be fed 1 to 2 kg of high-quality feed 10 to 20 days in advance. This can stimulate multiple ovulations, increasing the chances of larger litters. However, after mating, feeding levels should be reduced back to normal, as overfeeding can lead to higher embryonic loss. Third, during pregnancy, special attention must be given to the nutrition and care of sows, especially during the critical periods when embryo mortality is highest. The first peak of embryo death occurs between 9 to 13 days post-breeding, and the second peak happens around the third week of pregnancy, with mortality rates reaching up to 40%. During these times, stress factors such as sudden changes in environment, overcrowding, or poor feeding practices should be minimized. Sows should remain in their usual feeding routine for the first 3 to 4 weeks after breeding. In late pregnancy, the mortality rate increases again, so providing balanced nutrition becomes even more important. Fourth, the timing of the initial breeding is crucial. Sows should be bred once they have reached the appropriate weight and age, typically after showing estrus 2 to 3 times. For example, crossbred sows are usually ready for breeding at around 12 months of age and a weight of 100 kg or more. Fifth, preventing miscarriages is key. From 9 to 12 days after mating and 21 days before farrowing, sows should receive nutrient-rich diets high in protein, minerals, and vitamins. Fresh green feeds and quality concentrates should be provided while avoiding any spoiled, frozen, or moldy feed. Overcrowding, aggressive behavior, and stressful handling should also be avoided. Throughout the entire pregnancy, careful attention must be paid to feed quality, as moldy feed containing aflatoxins can lead to stillbirths, abortions, and poor growth in piglets.

Wet Strength Agent

With the constant improvement of economic level, people` requirements on the quality of paper are increasing high. A great number of paper products must have excellent resistance to fracture under moist state, in other words, must have a certain degree of wet strength. While the traditional papermaking wet strength agents are urea resin and melamino-formaldehyde, both belonging to formaldehyde resin with intense pungent smell and certain toxicity, and can be used in acid condition to acquire the wet strength. However the whiteness will descend a lot and the paper will be weak after the finished paper acquiring the wet strength. Polyamide polyamine epichlorohydrin resin (PAE) is water soluble, cationoid and thermosetting resin. This product is a non-formaldehyde polymer, non-toxic and tasteless, with a wide range of PH value and suitable for acid, neutral or slightly alkaline papermaking conditions, as well as the acid condition. Wet strength effect is better than the urea-formaldehyde resins and melamine formaldehyde resin. PAE resin, which is an excellent wet strength agent, develops fast in recent years with China`s paper industry development.

The high performance papermaking wet strength agent (PAE) that we produced has been widely used in a great amount of domestic factories and the finished paper products` wet strength index has surpass the similar products in domestic and foreign counties.

1. Performance Indicators

2. Application

PAE active ingredient is polyamide epichlorohydrin thermosetting resins that can be used as below:

1. Paper products with the need for drying or wiping water, such as: napkins, wet tissue paper, facial tissue, paper napkins, kitchen towels, wiping window paper, industrial wipes, lens wiping paper, cosmetic paper etc.;

2. Outdoor paper: such as kraft paper, packing paper, outdoor poster paper, construction paper, sack paper, map paper, germinating paper, fruit bag paper;

3. Wet wrapping materials: such as paper cups paper, meat paper, wrapping paper and boxes for fruits and vegetables, frozen and refined food packaging paper, pressure sensitive copy paper, filter paper, leaching processing paper and tea bag paper;

4. Paper soaked in water: as photographic raw paper. Instead of disposable textile products, such as hospital bed sheets, toilet paper and other disposable hospital garb.

Other issues such as cigarette paper, paper used for invoices.

PAE, as wet strength agent excellent efficiency (PAE), has been widely accepted by the papermaking industry

5. Storage Condition

Storage: Avoid direct sunlight, prohibiting contact with concentrated acids. Storage temperature is 0 ~ 35 ℃and the product can be stored for up to 3 months under 5 ~ 35 ℃.

4.Package and Transportation Safety

Package: 200 kg polyethylene barrels or 1000 kg IBC barrels.

Transportation: The product is non-flammable, non-explosive and low corrosive and non-dangerous. It can use plastic buckets as containers on railways, highways, aviation, marine to achieve the purpose of the safe transport, and if the leaking occurs during transportation, you can simply rinse on the spot.
