When Rumensin (monensin sodium) was fed to dairy cows: • Services per conception, days open and calving interval were increased, and firstservice conception rate was reduced in the 22 g/ton group. Pregnancy rates and successful calving rates were similar for all treatment groups. All measures of reproductive efficiency for all doses were well within accepted industry standards. • The incidence ...

One of the most important problem in feature-based visual servoing is the slow sampling rate and the delay of the camera that can make the closed loop system oscillative or unstable easily. In this paper, a linearized observer that estimates the object velocity and updates the visual information with the joint sampling rate is proposed. Stability of the observer-based control system and effecti...

OBJECTIVE Based on emerging preclinical findings suggesting that paternal smoking at conception may be a risk for ADHD in the offspring, we investigated whether a similar effect can be observed in humans. METHOD We analyzed data from an opportunistic dataset of girl probands with ( N = 140) and without ( N = 122) ADHD with available information on paternal smoking at conception. Data were ana...

The objectives were to evaluate effects of human chorionic gonadotropin (hCG) (3,300 IU i.m.) administered on d 5 after AI on CL number, plasma progesterone concentration, conception rate, and pregnancy loss in high-producing dairy cows. Following the synchronization of estrus and AI, 406 cows were injected with either hCG or saline on d 5 after AI in a randomized complete block design. Blood s...

Pregnancy in women aged 40 and above is frequently unplanned and the legal abortion rate is high in this age group. Contraception and fertility are shrouded in popular mythology and many women do not appreciate either their risk of conception or the range of methods available to prevent conception. Either hormonal or non-hormonal methods of contraception may be appropriate.
