Description
WET-BASE FERMENTED FEED FOR PERINATAL SOW AND PREPARATION METHOD THEREOF
TECHNICAL FIELD
The present invention relates to the technical field of animal feed, and in particular to a wetbase fermented feed for perinatal sows and a preparation method thereof.
BACKGROUND
Perinatal period of a sow refers to a period between 7 days before delivery and 7 days after delivery of a sow. In this period, sows are controlled by complicated physiological and endocrine activities, resulting in physiological changes, including sharp changes in hormone levels in vivo, a massive loss of body fluid, metabolic disorder, and exhausted labor, allowing them to be in a high stress and negative nutrition balance state. Sows’ digestive, immune, endocrine, and reproductive systems may further suffer from varying degrees of injuries, finally lowering their reproductive performance, limiting swinery production levels, and subsequently influencing economic gains in the breeding process. Providing sows with a high quality source of nutrition to increase feed intake, guarantee drinking quantity, improve nutrient digestibility, and promote gut health can help sows to reduce stress and lower management difficulties of perinatal sows.
Microbial fermented feed is a feed rich in highly active probiotics and metabolites thereof. To obtain this feed, different proportions of microbes are added in feedstuffs (e.g., soybean meal). Through microbial metabolism, macromolecular substances and anti-nutritional factors in the feed are decomposed and transformed to further help animals ingest and utilize. Not only can fermented feed improve degree of diet acidification, palatability, absorption and utilization rate of nutrients, but also promotes intestinal functions by increasing beneficial intestinal microorganisms and improves production performance of animals. Therefore, it is of realistic significance that addition of fermented feed in feed for perinatal sows may improve nutrient absorption in sows, promote gut health, and relieve constipation.
So far, however, most of commercially available fermented feeds for perinatal sows are wellprepared, dried fermented feeds. Such feeds facilitate the preservation and transportation; however, due to preparation at a high temperature and low water content, probiotics content is far below that in wet-base fermented feeds, and palatability and promoting effect on gut health are further inferior
2020100242 19 Feb 2020 to wet-base fermented feeds. Therefore, it is important to promote perinatal health and production performance of sows by developing and producing a wet-base fermented feed for perinatal sows, enabling its long-term preservation by means of a proper preservation method under breeding conditions, and guaranteeing quality.
