Facing the double test of non - pest + resistance, how to choose more cost-effective piglets


    In 2020, China's ban will be launched

　　On July 9, 2019, the Ministry of Agriculture and Rural Affairs of the People's Republic of China issued Notice No. 194, stipulating that "from January 1, 2020, all kinds of feed additives for growth-promoting drugs except traditional Chinese medicine will be withdrawn; As of July 1, 2020, feed manufacturers will stop producing commercial feeds containing growth-promoting drug feed additives (except traditional Chinese medicine).

       As is known to all, growth-promoting drug feed additives on the effect of piglet growth performance is at present no single for resisting additive products cannot achieve, the majority of feed manufacturers choose organic acids, probiotics, plant essential oil, plant extracts, antimicrobial peptides, and combinations of short chain fatty acid and other products in order to achieve the growth of the use of antibiotics.

　　African swine fever has discouraged farmers from using hog-derived materials

　　The first case of African swine fever (ASF) occurred in Shenyang, Liaoning Province, China on August 3, 2018. The outbreak has lasted for 15 months, and no breeding area in China has been spared. Before THE occurrence of ASF, porcine raw materials such as plasma protein powder and intestinal membrane protein were almost irreplaceable components in piglets' feed, but after the occurrence of ASF, their high risk of carrying non-asF virus made feed mills and farmers afraid to use them again.

　　In the face of non - pest + resistance, how to choose safe feed raw materials?

　　Facing the dual pressure of the forbidden and the blast resistance to pig industry, the safety of feed raw materials is particularly important at this time, the biggest problems facing the piglet stage was weaned stress syndrome, according to de-fa li academician of Chinese Academy of Engineering in the United States dairy export association feed technology seminar on the report, weaning weight 1 catty, output can be an average weight gain of 2.61 kg, and such can shorten the time of about 6.2 days, thus improve piglets after weaning feed intake and body weight is a very important to increase farmers earnings targets.

　　In order to increase the weaning weight of piglets, it is necessary to increase the feed intake in the nursing stage. In this stage, the lactase activity in piglets is higher, while the amylase activity is lower, so the digestion and absorption of lactose in piglets is better than that of plant raw materials. Therefore, whey powder becomes one of the best choices to increase the feed intake in the nursing stage.

        Whey powder as a kind of cheese production product, due to rich in lactose into piglet feed an important raw material, lactose can provide energy, improve piglet feed intake, increase pig weight, help beneficial bacteria value-added, reduce harmful bacteria, accelerate the growth of intestinal villus, enhance nutrient absorption, promote intestinal health.

　　In addition, the good news for whey powder application is that from September 17, 2019 solstice and September 16, 2020 (for a period of one year), China will no longer impose tariffs on feed whey imported from the United States (by weight, protein content 2%-7%, lactose content 76-88%), and the tariffs on feed whey from the United States will return to 2%. This greatly reduces feed mills' recipe costs for whey powder.

　　How much lactose does a piglet need at the conservation stage?

　　So how much whey should be added to the feed at the piglet stage? The south Dakota state university animal and animal sciences pig technical promotion expert Robert Dr Thaler in the United States dairy export association feed technology conference report, summarizes the pig nutrition guidelines from the United States, PIC and and a number of research institutions in colleges and universities about low protein whey powder adding in the piglet conservation phase quantity of research results, the conclusion is that every head of piglet need about 1000 g low protein whey powder. According to Dr. Qingping Liu of American International Raw Materials, a pig in China USES 404G of low-protein whey powder, which is only 40% of that in the United States. Therefore, it is necessary to increase the amount of lactose added to improve the quality of the feeding material in order to improve the health level, survival rate, production performance and input output of piglets.

The key point of quality control of low protein whey powder

　　How do we choose a quality milk raw material product at a low price? First of all, it is necessary to distinguish the differences between low protein whey powder, sweet whey, lactose and whey protein concentrate and other lactose source products, as shown in the table below:

　　In order to make better use of low-protein whey powder, several key points should be grasped: the crude protein in low-protein whey powder is mainly non-protein nitrogen, including urea, creatinine, uric acid, whey acid and ammonia, which has no nutritional value to monogastric animals, so it is unnecessary to overestimate the crude protein. The calcium, phosphorus and other milk minerals in the low-protein whey powder are all from the natural ash content of the milk source, and the biological utilization rate is very high, so in the formula to calculate the content of this part of the milk mineral, of course, we use the low-protein whey powder is mainly to use the lactose.

Why is American whey powder so popular?

　　The United States has vast land resources, efficient farms and processing facilities, sufficient supply of dairy cows, continuously improved dairy processing technology, and strict testing standards and regulatory processes to make its dairy products yield high and stable quality. As the world's largest dairy producer, the US produced 98.65 million tons of milk in 2018, three times the combined output of Australia and New Zealand. In 2017, the output of low-protein whey powder in the US was about 531,000 tons, equivalent to two-thirds of the global output. 75% of the total output of low-protein whey powder in the US was supplied to export markets.
