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 pursuit of family to the culturing economic benefit, sow year litter size and birth weight (quality of farrowing), outstanding weaning weight be the pith ignored do not allowed most that influences 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, body weight is gently bred under the situation.So that modern gilt even begun its breeding cycle at less than 200 ages in days.The commodity group of mean people sow age in days surplus 150 to 200 of oestrusing first generally.Litter size increases in addition, and is big to the demand of breast milk, and the wean age in days improves, and needs outstanding wean supports of reforming, and delivers for sale early, and the use that sow is given up more intensifies.Though sow has carrying capacity very to deal with the deficiency on the nutrition supply, just long-term nutrition overdraw can make the sow body condition descend, and influences some parameters of breeding.The nutrition condition of first farrowing sow and physical qualification, wean is to gap phase of oestrusing and sow life-span, and is closely bound up with the nutrition of sow, sufficient sow nutrition will reduce in the sow nutrition stress, pay attention to the nutrition of lactation especially.

The sow material generally is powder or common hard pellet diet at present, does not handle 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, the low or wean age in days prolongation of weaning weight.Culture-cycle is long, and cost is also high.Openly be not directed against the suitable expanded pellet diet of milking sow at present; This need be to material component, and the content of each material component is after suitable production technology etc. is rich in creative research and tests; 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 is adopted:
