CIDR Progesterone Implants for Cow


CIDR for cow, pack of 10

CIDR cow Insert Progesterone is given to cows and heifers as an implant. One form available in Australia is the CIDR Cattle Insert, which achieves synchrony by lengthening the oestrus cycle while it remains implanted. It releases progesterone, which is the same as the natural hormone produced by the corpeus luteum on the ovary between Day 7-17 of the normal cycle. When the implant is removed the progesterone level in the bloodstream drops quickly. This results in another egg developing and normal signs of oestrus behaviour are shown. The progesterone implants have the advantage over prostaglandins in that they will not cause abortions if they are used on pregnant animals (in fact they may have the opposite effect and may be able to help sustain some early pregnancies) and are also still effective if used on cows that have just been in season. Progesterone treatment can be used to stimulate the hormonal system of cows that are not cycling (anoestrus). The benefits of using the CIDR Cattle Insert include:

  • ~ AI programs can be completed in only a few days

  • ~ Better use of labour resources by spending less time on heat detection

  • ~ More accurate oestrus detection

  • ~ Fewer non-pregnant animals at the end of the breeding period

  • ~ Improved rates of genetic gain through better use of AI and ET

  • ~ Enhanced fertility in embryo transfer recipient

  • ~ Concentrated breeding, therefore concentrated calving

  • ~ Predetermined calving for special needs

  • ~ Manipulation of breeding to suit seasonal feed supply

  • ~ Reduced parturition to conception period.
