Breeding and management of sows play a crucial role in ensuring the health and productivity of the herd. The care of sows involves several key stages, including feeding for pregnant sows, nursing sows, and weaned sows. Among these, the nutrition of nursing sows is particularly important. They should be provided with high-quality feed rich in protein, minerals, and vitamins to support milk production, especially during the first month after birth. This ensures that piglets receive adequate nutrition for rapid growth. Immediately after birth, piglets should consume colostrum as soon as possible. Colostrum is rich in immunoglobulins, which are essential for passive immunity. Newborn piglets have a strong ability to absorb these antibodies, but this ability declines rapidly within two days. Therefore, early intake of colostrum is vital for building their immune system.
In addition to proper nutrition, breeding boars require careful management. A balanced diet and appropriate exercise help maintain their sexual drive and overall health. This, in turn, improves semen quality and quantity. Breeding schedules should be planned carefully, especially when it comes to inbreeding. Young boars (1–2 years old) are still developing and can be bred 1–2 times per week. Adult boars (2–5 years old) are more mature and can be bred up to twice daily. It's important to avoid overfeeding or underfeeding, as both can negatively affect reproductive performance. Boars should also be kept in good physical condition throughout the year.
For special wild boars, hygiene and disease prevention are essential. These animals are naturally clean and have strong resistance to diseases, but regular disinfection is still necessary. Pens should be cleaned regularly, ideally once every two weeks using solutions such as 10–20% lime water, 10% potassium permanganate, or 5–10% bleach. Sows must be thoroughly cleaned before and after farrowing, as well as when pigs are moved. Daily sweeping of the pen is recommended to maintain a clean environment. Clean water should always be available, and pigs should be encouraged to develop good habits by eating, sleeping, and defecating in designated areas. Proper ventilation and temperature control are also important during extreme weather conditions.
Vaccination is a key component of disease prevention. Common vaccines include those for swine fever, erysipelas, and porcine pulmonary disease. Pigs should receive one dose every six months at 2ml per head. Piglets should be vaccinated according to a schedule: an edematous vaccine within 15 days, a paratyphoid vaccine at 20 days, and a triple vaccine at 30 days. Within 48–72 hours after birth, a 1.5ml intramuscular injection of vitamin is recommended. For skin rashes, a 1–2% trichlorfon solution mixed with 0.05% sterilized ester can be sprayed. Insecticides like insect killer or specific treatments can also be used for lice control. Prevention starts with maintaining a clean and dry environment.
Wild boars should also be treated for internal parasites every six months. This can be done by mixing insecticides into their feed for 5–7 days to eliminate adult worms and eggs. In addition, antibiotics such as terramycin powder, tylosin, or new toxins can be added to feed for general disease prevention. Overall, a combination of proper nutrition, hygiene, vaccination, and parasite control is essential for maintaining a healthy and productive pig population.
Moisturizing Raw Materials
What are the best moisturising ingredients ingredients
Moisturizing ingredients in cosmetics can be divided into the following categories:
1. natural moisturizing factors: this type of moisturizing raw materials mainly include Amino Acids, urea, lactic acid, sodium PCA, etc. They can simulate the skin's natural moisturizing mechanism to provide long-lasting moisturizing effect.
2. Polyols: including glycerin, propylene glycol, butylene glycol, etc. These ingredients have good hygroscopicity, which can adsorb water in the air and provide moisture to the skin.
3. polysaccharides: such as hyaluronic acid, alginate, etc., this kind of ingredients can form a protective film on the skin surface, preventing water evaporation, to provide long-lasting moisturizing effect.
4. Fatty acids: such as fish oil, olive oil, etc., these ingredients can provide moisturization for the skin and improve the dryness of the skin.
5. proteins and peptides: such as serine, collagen, etc., these ingredients can enhance the skin's ability to moisturize, improve skin elasticity.
6. plant extracts: such as aloe vera, rose, witch hazel, etc., this kind of ingredient is rich in active ingredients, can provide the skin with sufficient moisture and nutrition.
