we want to compare the efficacy and safety of vaginal versus sublingual misoprostol for cervical ripening and induction of labor. this randomized clinical trial was performed on 140 women with medical or obstetric indications for labor induction. the patients were randomly divided into two groups: vaginal and sublingual administration of misoprostol. in first group, 25 µg misoprostol was placed...

The cow mammary transcriptome was explored at -30, -15, 1, 15, 30, 60, 120, 240, and 300 d relative to parturition. A total of 6,382 differentially expressed genes (DEG) at a false discovery rate ≤ 0.001 were found throughout lactation. The greatest number of DEG (>3,500 DEG) was observed at 60 and 120 d vs. -30 d with the largest change between consecutive time points observed at -15 vs. 1 d a...

Nutrition has a significant effect on reproduction and lactation in Ruminant. Supply of require nutrient of dairy cows and ewes in early lactation is the main challenges that will be considered, since in most cases the animals facing negative energy balance after calving and the beginning of the period of lactation. Negative energy balance may sometimes result in reduced livestock production an...

The study aimed to determine factors affecting the dry period length and effect of dry days on milk yield, milk composition and lactation length in the next lactation of dairy cows. Data used for analysis included 7264 lactation records collected from 2012 to 2016 on 4737 Holstein cows raised in 152 herds. The statistical model used to determine the factors influencing the dry period length sho...

osteoporosis is considered as an important public health problem especially in postmenopausal women. there are some hypotheses support the contributory effect of pregnancy and lactation on osteoporosis later in life. high calcium demand during pregnancy and lactation and low estrogenic state support those hypotheses. numerous studies have investigated on the issue but there is no consensus abou...

in this study a total of 171,360 monthly test day milk records obtained from first lactation of iranian holstein cattle (three times a day milking) distributed in 96 herds and calved from 1999 to 2008 were used to estimate genetic parameters and to predict breeding values of the animals. the data was analyzed using random regression test day model. the results showed that average of heritabilit...

in order to estimate the genetic parameters and comparison legendre polynomials for production traits of iranian holstein dairy cattle test-day records of first lactation cows for milk yield, fat yield, protein yield, fat percentage and protein percentage traits were used. these records collected from 2006 to 2010, by the animal breeding center of iran. the genetic parameters were estimated usi...
