Abstract:
This study was achieved in one of the fields of special factor in Basaer village
Euphrates in Heet district l Anbar,. For the period between 1/2/2014 to 1/7/2014, 40 local female goats aged 2-4 years with a weight ranging from 35-40 kg, and
at least one birth, all female goats were examined using an ultrasound machine.
Sonar) to make sure they are free of pregnancy before the start of the
experiment. Females were randomly divided into two equal groups (20 goats in
each group), Female group I (T1) was treated by placing the one-time used cider
in the vagina for 12 days. Upon removal eCG 500 IU was injected into the
muscle withdrawal, Females of the second group (T2) were treated with the
application of the vaginal progesterone (CIDR) device containing 0.3 g
progesterone for 12 days removal, withdrawal eCG 500 IU was injected into the
muscle. The females were inseminated through the release of males with them at
the end of the hormonal program and the male was rotated between the cages to
avoid the differences caused by male influence and continued presence of males
with females for five days. The results of the study showed the superiority of the
new CIDR group over the CIDR group used no significantly in the performance
reproductive. The results of the present study showed an increase in the weight
of newborns due to the impact of the weight of the mother, and that hormonal
treatments used in the standardization of estrus did not affect the weight of
births at birth or their vitality. However, the results showed that the births of
high-weight mothers led to increased birth weight and increased vitality and
preserve their life after birth. We conclude from the present study that the use of
CIDR in standardizing estrus gives good results and improves reproductive
performance in goats when injecting hormone eCG, can be reused CIDR again
and gives acceptable results.
