Abstract

The invention discloses an extruded hard pellet feed for lactating sows, which is prepared by the following raw materials in parts by weight: 50-55 parts of corn, 3-4.5 parts of imported super steam fish meal, 3-5 parts of fermented soya bean meal, 8-10 parts of flour, 10-15 parts of wheat, 13.5-15.1 parts of non-transgenic soya bean, 2-4 parts of rapeseed meal, 5-10 parts of extruded-soybean, 1-2 parts of mineral substance premix, 0.2-0.3 parts of vitamins premix, 1.0-2.0 parts of calcium hydrogen phosphate, 2.5-4 parts of soybean oil, 1-2 parts of calcium propionate and 0.1-0.2 parts of oligosaccharide. The extruded hard pellet feed is prepared by tempering the raw materials in the formula by using a double-shaft squeezing well-done extruder under a certain condition and then curing under a certain curing condition. The crude protein of the extruded hard pellet feed is greater than 16.2%, the curing degree is above 80%, the extruded hard pellet feed has comprehensive nutrition and extrusion, the anti-nutrition factors are destroyed, and after the extruded hard pellet feed is used for feeding pregnant sows, the birth weights of piglets are above 1.6 kg in average.

Description

Expanded hard pellet diet of a kind of milking sow and preparation method thereof
Technical field
The present invention relates to the feed of milking sow (conceived 84 days-wean), be specifically related to expanded hard pellet diet of a kind of milking sow and preparation method thereof.
Background technology
Along with the raising of breed improvement, feeding and management technical merit, support the family to the pursuit of fanning economics, sow year litter size and birth weight (quality of farrowing), outstanding weaning weight be the pith ignored do not allowed most that affects economic benefit.Sow is produced recent two decades per year, and great change has been experienced in the management of multiparity sow and gilt, and gilt is less at the monthly age, breed in the lighter situation of body weight.So that modern gilt has even begun its breeding cycle at less than 200 ages in days.Commodity group of mean people sow oestruses first generally at 150 to more than 200 ages in days.Litter size increases in addition, and is large to the demand of breast milk, and Weaning Age improves, and needs outstanding wean supports of reforming, and delivers morning for sale, and the use of sow house is more intensive.Although sow has unusual carrying capacity to deal with deficiency on nutrition supply, just long-term nutrition overdraw, can make the sow body condition descend, and affects some parameters of breeding.The nutrition condition of first farrowing sow and physical qualification, wean is to the gap phase of oestrusing and sow life-span, and is closely bound up with the nutrition of sow, sufficient sow nutrition will reduce in sow nutrition stress, you should pay special attention to the nutrition of lactation.
The sow material is generally powder or common hard pellet diet at present, does not process through expanding processing, and pelleting temperature is not higher than 85 ℃, efficiency of feed utilization is low, has ANFs, and litter size is low, the piglet birth weight is low, and the sow output of milk is not enough, and the low or Weaning Age of weaning weight extends.Culture-cycle is long, and cost is also high.There is no at present open suitable expanded pellet diet for milking sow, this need to be to material component, the content of each material component, after suitable production technology etc. is rich in creative research and test, just can obtain being suitable for milking sow ingests, and nutrition is reasonable, and the digestive utilization ratio of expanded pellet diet is high, the expanded hard pellet diet of the milking sow that feed coefficient is lower.
Summary of the invention
The invention provides a kind of milking sow expanded pellet feed and preparation method thereof, the feed of gained has well doneization, and digestive utilization ratio is high, good palatability, ANFs is destroyed, and the characteristics that feed coefficient is lower are particularly suitable for the expanded hard pellet diet of milking sow.
The present invention solves the problems of the technologies described above the technical scheme that adopts:
A kind of milking sow expanded pellet feed is characterized in that: by the raw material dubbed feed base-material of following weight parts: corn 50~55, the super steam fish meal 3~4.5 of import, fermented bean dregs powder 3~5, flour 8~10, wheat 10~15, non-transgenic dregs of beans 13.5~15.1, rapeseed dregs 2~4, expanded soybean 5~10, mineral substance premix 1~2, vitamin premix 0.2~0.3, calcium monohydrogen phosphate 1.0~1.2, soya-bean oil 2.5~4, calcium propionate 1~2, oligosaccharides 0.1~0.2.
