Embodiment

[0021] A feeding method for promoting rumen development of lambs / calf. The feeding ration adopted includes precise calf milk replacer, precise lamb starter, concentrated feed and alfalfa. The nutritional components are shown in Table 2.

[0022] Table 2

[0023]

[0024] On the 5th day after the lamb was born, that is, when the lamb was 5 days old, the lamb was separated from the ewe, and the milk replacer was fed separately. The hours are 7:00 am, 11:30 noon, 16:00 pm and 20:30 pm.

[0025] At the age of 9 days, the average feed intake of lamb milk replacer was 147g / day / head. The feeding amount of milk powder at the age of 10 days was 147g / day / head, and then reduced by 5g / head every day until the feeding amount of milk replacer powder reached 30g / day / head, and was fed three times a day at 7:00 am, 13:30 noon and 20:00 pm. Starter and alfalfa were added at the age of 10 days. The alfalfa was cut into 6-8 cm long, and the starter and alfalfa were free to eat.

Abstract

The invention relates to the technical field of animal husbandry breeding, in particular to a breeding method for promoting lamb/calf rumen development. A feeding ration adopted in the breeding method comprises baby meal, starter feed, concentrated feed and alfafa. A pup eats breast milk after birth. The pup is separated from a dam when being five-days old, is fed with the baby meal four times a day, and is not limited in ingestion. When the pup is nine-days old, the baby meal ingestion quantity of each pup is measured, and a reference is provided for limiting baby meal ingestion. The starter feed and the alfafa are added when the pup is ten-days old and can be freely ingested by the pup. Meanwhile, the ingestion quantity of the baby meal is limited and gradually reduced by days, and the baby meal is fed three times a day for promoting the ingestion of the starter and the alfafa. The pup is weaned when being 38-days old, the baby meal and the starter feed are stopped feeding and changed into the concentrated feed for feeding adult animal, the ingestion of the concentrated feed is limited, and the alfafa still can be freely ingested.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a feeding method for promoting 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 yet been established. Compared with...
