Feed for weaned piglets and feeding method thereof

Abstract

The invention discloses a feed for weaned piglets. The feed is composed of Zhubao rice flour, a creep feed and a piglet feed. The Zhubao rice flour and the creep feed are used for breeding a piglet both three days before weaning and three days after weaning; then the piglet feed gradually replaces the creep feed for feeding of the piglet within 7 days; and then about 30 kg of the piglet feed is used for feeding the piglet for 30 to 35 d, and the body weight of the piglet is increased to 30 kg. According to the invention, based on the characteristics of the growth of piglets in different growthstages, the feed conforming to the growth characteristics of piglets is provided on the premise of reducing the usage amount of antibiotics; the feed digestion and absorption rates of the piglets areincreased; the stress syndrome of the piglets is reduced; the diarrhoea rate of the piglets is lowed; the survival rate and growth speed of the piglets are improved; and the weight uniformity of a pig group is enhanced.

Description

technical field [0001] The invention belongs to the technical field of suckling pig feed, and in particular relates to a weaned suckling pig feed and a feeding method thereof. Background technique [0002] Stage feeding of suckling pigs is a bottleneck restricting pig production. In order to improve the economic benefits of pig raising, the early weaning technology of weaning piglets at the age of 3-4 weeks is generally adopted. However, the body of early weaned piglets is in the critical period of young development, and its own functions are not perfect. Coupled with the influence of many factors such as environmental changes and pathogenic microorganisms, the structure of the intestinal mucosa has changed, resulting in strong weaning stress. , resulting in reduced appetite, indigestion, low feed utilization rate, slow growth, decreased disease resistance, diarrhea and edema, growth retardation, and even death of piglets. These stress reactions are collectively referred to a...

[0003] Patent CN102450342B discloses a weaned suckling pig feed and its feeding method. The feed is composed of suckling pig milk powder and suckling pig feed composed of a new formula; Feed the suckling pig milk powder 4kg until the age of 59-65 days, and then feed the suckling pig feed 20kg until the suckling pig is 59-65 days old. This method can improve the growth rate, health and safety of the suckling pig to a certain extent, but there are still the following Insufficient: (1) The formula in this patent is a traditional formula, and the content of the formula corn is relatively high, and the corn itself is susceptible to mold and produces toxins. Risk of disease in pigs; (2) This patent uses whey powder to provide a large amount of lactose for piglets, which can reduce the pH value in the digestive tract of piglets and inhibit the reproduction and growth of pathogenic bacteria. In a wet environment, whey powder will deteriorate if stored for too long, which will reduce the digestion and absorption rate of feed by piglets, and the high salt content in whey powder is not conducive to the growth of piglets; (3) the patent also contains plasma protein powder , although the substance has a good growth-promoting effect on feeding suckling pigs, in recent years, the industry has increasingly opposed the use of plasma protein powder, mainly as follows: First, how to ensure that plasma protein powder does not contain viruses ? If the virus is not completely inactivated during processing, it will easily infect pigs after feeding, and even bring a huge risk of virus mutation; secondly, is the use of "homologous" products scientific? Plasma protein powder is obtained by separating pig plasma, and the biggest risk of transmission of "homologous" products is blood products. The impact of using homologous products is unpredictable, and there are great hidden dangers of disease and food safety. "Mad cow disease" is a typical feeding "homologous" product
