Feeding method capable of promoting rumen development of lambs/calves

Abstract

The invention discloses a feeding method capable of promoting rumen development of lambs / calves. The technical scheme of the feeding method capable of promoting the rumen development of the lambs / calves has the following key points of: adopting milk-replacement powder, a starter feed and a concentrated feed as the daily ration of the feeding method; starting feeding young animals, namely the lambs / calves, with the milk-replacement powder when the young animals are 5 days old and weaned, and adding trace acetic acid, propionic acid and butyric acid into the milk-replacement powder for two timesso as to promote adaption of intestines and stomachs of the young animals to volatile fatty acids in advance; gradually reducing the dosage of the milk-replacement powder, and adding the starter feed; mixing the concentrated feed with the milk-replacement powder and the starter feed from the 15th day; stopping using the milk-replacement powder from the 20th day; and then, stopping using the starter feed from the 31st day. The feeding method capable of promoting the rumen development of the lambs / calves has the following advantages: compared with traditional distributed feeding methods, the feeding method can make the young animals to start to only take the concentrated feed in only 30 days, so that higher breeding and feeding efficiency is achieved so as to promote separation of the younganimals from mother animals as early as possible, thereby allowing the mother animals to enter a next round of breeding as soon as possible; and moreover, the feeding method is also capable of promoting production performance of the young animals, thereby beneficially avoiding various adverse effects caused by weaning.

Description

technical field [0001] The present invention relates to a kind of animal husbandry feeding method, more specifically, it relates to a kind of feeding method that promotes lamb / calf rumen development. Background technique [0002] The rumen is vital for ruminants. The rumen of adult ruminants inhabits a large number of microorganisms that can help digest cellulose and hemicellulose that monogastric animals cannot digest. As neonatal ruminants develop into adulthood, their rumen undergoes major structural and physiological transformations. Before the lamb / calf eats the solid diet, the rumen is not fully developed, and there is no fiber digestion function, and all or the necessary nutritional needs are provided by milk or milk replacer, which is ingested by the lamb / calf After that, it directly enters the abomasum through the esophageal groove, similar to monogastric animals. Rumen development begins with the intake of solid feed. The rumen microflora of lamb / calf has not y...

Problems solved by technology

Roughage is also critical in the development of the rumen in young ruminants, and insufficient supply can lead to irregular branching of the rumen teats and incomplete keratinization of the rumen, affecting animal health
