Description
Technical field:
The invention belongs to livestock-raising technical fields, and in particular to a kind of low ratio roughage for promoting fattening lamb weight gain
Daily ration and preparation method thereof.
Background technique:
In the intensive cultures such as modern milk cow, beef cattle, mutton sheep, people are in order to pursue higher economic benefit, ruminant
Feed high energy, high starch daily ration.High energy, high starch daily ration ferment in ruminant body, and to generate a large amount of volatile fatty acids poly-
Collection declines the pH value of rumen fluid sharply in cud.When rumen fluid pH value is too low, ruminant tumor gastric acid poisoning can lead to, and draw
It sends out the symptoms such as complication such as hepatapostema, founder, diarrhea and inflammation a series of, seriously endangers the development of aquaculture.Ruminant
Enough fibers of searching for food are conducive to stimulation and ruminate and chew, and maintain normal rumen ph, reduce animal and lead because searching for food excessive fine fodder
Cause the risk for suffering from SARA.Fiber is often indicated with NDF in daily ration, is divided into roughage source (FNDF) and essence according to the source of NDF
Feed resource (NFF).Partial size contained by the NDF of fine fodder source is shorter to stimulate ruminant to chew, and generate saliva, maintain cud
The stabilization of environment；The partial size of roughage source NDF is longer can to stimulate ruminant chewing, ruminate, and can promote point of saliva
It secretes.However, the crude fiber content in daily ration is excessive, the energy concentration of daily ration on the one hand can be reduced, influences the feeding value of feed,
On the other hand, a large amount of fiber accumulations be will cause when dietary fiber is excessively high in cud, the space of cud is filled, reduce ruminant
Feed intake influences the production performance of animal.
Stalk nutritional ingredient itself is poor, and feeding value is lower, and largely addition will cause the productivity of animal in feed
It can decline.But fiber diameter contained by stalk is larger, and facilitates ruminant and form straw mattress layer in cud, in high yield animal
Demand of the animal to fiber had been able to satisfy not only with less amount addition in daily ration, but also roughage can be hindered to fill out the cud of ruminant
It fills and feed intake is caused to decline, while being also able to satisfy demand of the high yield animal to energy.In the U.S., many farms are by stalk
It is applied in fattening diet as a kind of fibre resources.But stalk with the addition of what kind of ratio just can ensure that animal gives birth in daily ration
It is maximum to produce performance, and the research for not damaging animal rumens health is less.IRA feeds system recommendation ruminant and comes from crude feed
