The objective of the study was to compare three systems for detection of estrus and combinations of these systems on a large commercial dairy (1000 lactating cows) during stress of summer heat. At 37 to 45 days in milk (DIM), 266 cows were fitted with a HeatWatch (HW) device (HeatWatch; DDx Inc., Boulder, CO), an activity (A) sensor (ALPRO; DeLaval Inc., Kansas City, MO), and observed visually ...

Although the number of dairy farms is decreasing, that of large farms is increasing in Japan. Milk production in Japanese dairy cows has increased from 62 kg/year to 88 kg/year over the last 2 decades. However, Japanese dairy cows are experiencing a sustained decline in reproductive performance, calving intervals, and days open; further, the number of inseminations required for conception have ...

Preeclampsia which happens in 5-10% of pregnancies is associated with maternal and prenatal morbidity and mortality in all over the world. Preeclampsia leads to high rates of preterm birth, small for gestational age infant. The objective of the present study was to evaluate the effects of paternal cigarette smoking before and in conception on risk of preeclampsia in non smoker women without exp...

BACKGROUND This paper assesses the risk of cerebral palsy (CP) in children born after assisted conception compared with children born after natural conception (NC). METHODS This population based follow-up study included all 588,967 children born in Denmark from 1995 to 2003.

Gestational stress is believed to increase the risk of pregnancy failure and perinatal and adult morbidity and mortality in both the mother and her child or children. However, some contradictions might arise from methodological issues or even from differences in the philosophical grounds that guide the studies on gestational stress. Biased perspectives could lead us to use and/or design inadequ...

Italy represents an unexpected and in some ways paradoxical outcome in terms of fertility control: one of the lowest birth rates in the world seems to have been accomplished through the preponderant use of “traditional” methods. Compared to other countries, there has been a reluctance to abandon coitus interruptus. In France in 1994, 84% of women used IUDs or the pill, compared to 42% in Italy ...

To clarify effect of postbreeding intramuscular administration of deslorelin on mares, plasma LH and progesterone concentrations and conception rate were evaluated. In Experiment 1, deslorelin, buserelin, or a placebo was administered on day 9 (day 0=day of last breeding or AI). Plasma samples were collected daily from days 6 to 15, and additional samples were taken after treatment. There was a...
