LOW COST, INDIGENOUS CRADLE FOR SAFE RESTRAINING OF SHEEP FOR PREGNANCY DIAGNOSIS.

摘要

The present investigation, low cost,indigenous cradle for safe restraining of sheep for pregnancy diagnosis is related to design and fabrication of simple, indigenous, safe and cost-effective cradle for fast scanning of sheep for pregnancy diagnosis. The requirement of cradle is pre-requisite for scanning of sheep in comfortable condition. This equipment can easily be assembled by Indian manufacturers. This cradle is made up of the following components: (i) a rectangular platform open from back and on both lateral side attached with vertical iron pipes (ii) front side of cradle is attached with a gate (iii) both side portion to standing platform attached with two lateral gliding rods (iv) stairs for easy movement of sheep (v) cradle is mounted on rollers for its easy movement. The stairs of the cradle helps sheep to move comfortable towards the platform and after scanning sheep can come down with out any risk of falling of sheep or any injury. The two gliding stands attached with the both lateral side of the platform help in holding the sheep according to sheep body width and length. The small gate attached to the front side of the platform has two gliding rods by which the neck of the sheep can be restrained gently. The material used in cradle is made-up of 16 gauze iron pipe (rectangular and spherical). Animal is scanned in the cradle in standing position. The operator generally used to stand near left flank of sheep. For transabdominal ultrasonography a probe of 3.5 to 7 MHz is placed on the groin side of the ewe. Lubricant is used to maximize the contact between probe and skin. The ideal and reliable period for transabdominal ultrasound is between 40 and 90 days of gestation. The utilization of this cradle for ultrasonography of sheep may result in safe and accurate scanning with out the fear of abortion and injury to the sheep. In conventional methods minimum two labours are required to restrain the ewe on its hip. In this improved cradle sheep posture did not disturbed during the scanning which intern will facilitate easy and fast scanning and ultimately helps in augmenting sheep production.
