Supplementary feeding pens for early weaning of lambs

Abstract

The invention discloses a supplementary feeding pen used for weaning lambs from breast milk in an early period. The pen comprises a feeding supplement groove; a plurality of milk supplement nipples and a plurality of branch screw material feeding tubes are arranged over the feeding supplement groove, and the arrangement of the milk supplement nipples and the branch screw material feeding tubes meets one-to-one correspondence; a plurality of supplementary feeding fences are arranged in front of the feeding supplement groove; a supplementary feeding passage through which lambs can pass is formed between each two neighbouring supplementary feeding fences; a flat floor is arranged at the bottom of each supplementary feeding passage; a footboard is arranged on each flat floor; a weighing sensor is arranged between each group of footboard and flat floor; an end part of each supplementary feeding passage is equipped with a group of milk supplement nipple and branch screw material feeding tube; the upper end of each branch screw material feeding tube communicates with the bottom of a main screw material feeding tube through a branch material inlet channel; and the main screw material feeding tube communicates with the bottom of a feeding mixing barrel through a main material inlet channel. The supplementary feeding pen provided by the invention has a reasonable structural design, is more scientific and effective in weaning, can reduce the feeding cost, and can reach a good feeding effect.

Description

technical field [0001] The invention relates to the technical field of lamb feeding, in particular to a supplementary feeding bar for lambs weaned from mother's milk in the early stage. Background technique [0002] The weaning time and method of weaning lambs is a noteworthy issue of feeding management strategy. Weaning is a stressful period in a lamb's life, manifested by a slowed or stopped production rate and sometimes even weight loss. The level or extent of this weaning shock depends on the age and weight of the lamb at weaning, as well as the feeding regimen prior to weaning. Studies with lambs and goats have shown that body weight at weaning is more important than age at weaning in order to minimize the effects of weaning shock. Lambs and goats fed solid feed during lactation were less affected by the weaning shock than lambs not fed solid feed. Other factors affecting weaning shock were: male lambs were more affected by weaning shock than ewe lambs, and healthy g...

Problems solved by technology

However, most of the existing supplementary feeding pens only have the function of supplementary feeding, and it is difficult for lambs to achieve more scientific weaning
