In sika deer, the normal method of estimating fetal age, based on fetal weight, is not applicable during the early pregnancy period. The objective of the present study was to describe the growth and development of sika deer fetuses and to establish a method for fetal age estimation during early pregnancy using ultrasonography. Five captive female Hokkaido sika deer (Cervus nippon yesoensis) wer...

The assessment of the powers of body measurements in the estimation of weights and the accuracies of body weights in the estimation of size among livestock species has been widely reported. Body weight is the commonly reported measure of size (Fitzhugh & Bradford, 1983). The reliability of single measurements such as wither height, body length, heart girth, rump height and width e.t.c. in the e...

The degree of fetal growth restriction has been unclear in equine reproduction. In this study, 2,195 fetuses from 2,137 abortions during 11 seasons were examined to determine the causes of abortion, and fetal size dimensions (crown rump length and body weight) were measured. In total, 900 cases (42.1%) of abortion were identified as caused by viral infection (215, 10.1%), bacterial infection (1...

background: our previous studies revealed anethum graveolens l. caused some changes in female reproductive system that induced infertility. therefore, in this study, oocyte changes as one of probable reasons of infertility were investigated.    methods: in this study, 59 adult female rats were divided into 3 groups of control, low dose (0.5 g/kg) and high dose (5 g/kg) of dill seed aqueous extr...

Chromatin insulators are DNA-protein complexes that are situated throughout the genome that are proposed to contribute to higher-order organization and demarcation into distinct transcriptional domains. Mounting evidence in different species implicates RNA and RNA-binding proteins as regulators of chromatin insulator activities. Here, we identify the Drosophila hnRNP M homolog Rumpelstiltskin (...

to study of environmental effects (sex and age) on fleece traits of dromedary camel in sistan and balouchestan province, 48 male and female which rose in five cities (zahedan, zabol, khash, iran-shahr and ghabahar) belonging to three age groups (7 years) were measured. results indicated that there was not significantly different between sexes and age groups for all of fleece parameters, expect ...
