Key Points and Measures for Health Care Technology of Finishing Pigs Explained in Detail

Applying small peptide nutrition to finishing pigs to promote growth, and applying "Dazhuangsu" or "Dazhuangsu-B" to eliminate mycotoxins in feed can improve the body's disease resistance and greatly reduce the occurrence of diseases; in addition, eliminating ammonia gas, hydrogen sulfide and asthma in livestock housing, controlling respiratory disease complex, shortening the feeding period by more than 10 days, and improving feed conversion rate and meat quality.

Small peptide nutrition and its health care

The previous view held that protein digestion always occurs in the intestine, where it is digested into individual free amino acids and then absorbed. Research over the past twenty years holds that protein in the intestine is not entirely digested into free amino acids, and part of it is digested into small peptides (dipeptides and tripeptides). It has also been found that small peptides have the following four major effects: eliminating the absorption competition of free amino acids; accelerating protein synthesis, improving carcass lean meat percentage and carcass quality, and reducing PSE meat; improving production performance; and facilitating the absorption and utilization of minerals. The "Xiaotaishu" developed by Changsha Luye Biotechnology Co., Ltd. has the effect of causing protein entering the body to produce large amounts of dipeptides and increasing the activity of dipeptide absorption carriers. Practice has proved that adding Luye "Xiaotaishu" to the diet at 0.2-0.3% increased protein utilization by 15%, significantly reduced PSE meat, and clearly improved feed conversion rate, daily weight gain, carcass lean meat percentage and meat quality. The specific method of use is: add 0.3% to the diet of piglets and growing pigs, and add 0.2% to the diet of large pigs.

Eliminating subclinical levels of mycotoxins and improving disease resistance

According to research, the effects of subclinical levels of mycotoxins on pigs include four aspects: affecting palatability; loss of nutrients; increased PSE meat and decreased lean meat growth potential; and immunosuppression. Among these, immunosuppression caused by mycotoxins reduces the body's disease resistance, leading to pigs being susceptible to more than thirty diseases such as swine fever, influenza, colibacillosis and eperythrozoonosis, with increased incidence, and finishing pigs having their feeding period extended by more than 5-10 days on average, with costs increasing by 10-30 yuan per head. Therefore, eliminating the effects of mycotoxins can significantly improve the body's disease resistance, release lean meat growth potential, and improve feed conversion rate and meat quality. Specific methods: first, improve disease resistance, for auxiliary treatment of asthma, add Dazhuangsu or Daqiesu-B at 1%; second, prevent disease and promote growth and improve meat quality: add 0.8% Dazhuangsu at 30-75 kg, and add 0.5% Dazhuangsu above 75 kg; third, use in combination with small peptides: add 0.4% Dazhuangsu + 0.2% Xiaotaishu at 30-75 kg, and above 75 kg: 0.2% Dazhuangsu + 0.2% Xiaotaishu. Health-demonstration pig farms may also use the following formula for health-care feeding: add 0.8% Daqiesu-B at 20-30 kg; add 0.6% Daqiesu-B at 35-60 kg; add 0.5% Daqiesu-B from 60 kg to slaughter.

Respiratory disease complex and ammonia removal and deodorization in livestock housing

The respiratory mucosa of animals can secrete large amounts of mucus and lysozyme, which can adhere to bacteria, viruses and dust and kill pathogenic microorganisms. The respiratory mucosa also secretes large amounts of cilia, which can expel the adhered bacteria, viruses and dust from the body. High concentrations of ammonia gas and hydrogen sulfide in pig housing can damage the respiratory mucosa, reduce disease resistance, and prevent it from effectively adhering to, killing and eliminating bacteria, viruses and dust, thereby destroying the natural barrier of the animal's respiratory system and leading to mixed infections of various bacteria and viruses. High concentrations of ammonia gas in livestock housing have become one of the most important triggers of the high incidence of respiratory diseases. Therefore, ammonia removal and deodorization are of great significance for preventing respiratory diseases.

Ammonia removal and deodorization must adopt comprehensive health-care measures, specifically doing the following work:

(1) Do a good job of environmental sanitation and clean up manure in a timely manner; (2) provide appropriate ventilation; (3) apply the ideal protein principle to appropriately reduce the amount of soybean meal and reduce ammonia emissions; (4) apply the ammonia-removal and deodorizing health-care premix "Anjing". This patented technology was developed by experts such as Wen Lixin. The specific formulas are as follows: 20-51 kg: corn 62%, wheat bran 10%, soybean meal 24%, Anjing No. 1 4%; 50-80 kg: corn 62%, wheat bran 12%, soybean meal 22%, Anjing No. 2 4%; 80 kg to slaughter: corn 62%, wheat bran 14%, soybean meal 20%, Anjing No. 3 4%.

Health care and rehabilitation for asthma

Asthma is a contagious infectious disease caused by Mycoplasma hyopneumoniae, with cough and asthma as its clinical features. The pathogen mainly attacks the cilia of the respiratory mucosa, destroying the mucosal cilia, the most important defense system of respiration, and opening the door to infection by other respiratory pathogens. It has become the chief culprit and core pathogen of respiratory disease complex. This disease exists in 90% of pig farms in China, and the annual economic loss caused by asthma nationwide reaches 7 billion yuan.

Pigs that recover from asthma can obtain strong immunity. Research by experts such as Wen Lixin found that the pathogenesis of acute asthma is similar to the allergic phenomenon in immune stress, and the clinical manifestations of chronic asthma are similar to immune stress. The research group's experts regarded asthma infection as natural immunity and immune stress caused by immunity, and developed "Kangchuan No. 1" to eliminate immune stress, achieving success (one national patent applied for). Specific health-care measures: (1) Health care and rehabilitation for chronic asthma in old epidemic areas: add "Kangchuan No. 1" at 2% and feed for 10-15 days, then feed at 1% for 10 days; (2) Health-care nursing during the rehabilitation period of acute asthma: for acute asthma, first use drug treatment, and after symptoms have somewhat eased and pigs begin to eat, add 2% Kangchuan No. 1 to the feed for health-care nursing for 15 days to promote recovery.
