The purpose of this study was to determine the relationships between conception rate and other parameters before estrus synchronization with a Controlled Internal Drug Release Device (CIDR) and estradiol benzoate (EB). In the estrus synchronization program, animals were injected with 2 mg EB and then received a CIDR. Seven days later, the CIDR was removed and the animals were given an injection...

AIM To evaluate estrus induction response and fertility including plasma progesterone and biochemical profile following use of three standard hormonal protocols in anestrus crossbred cows. MATERIALS AND METHODS The study was carried out on 40 true anestrus and 10 normal cyclic cows. 10 anestrus cows each were treated with standard intravaginal controlled internal drug release (CIDR) device, O...

As we enter the era of data deluge, turning data into knowledge has become the major challenge across most sciences and businesses that deal with data. In addition, as we increase our ability to create data, more and more people are confronted with data management problems on a daily basis for numerous aspects of every day life. A fundamental need is data exploration through interactive tools, ...

While “no one size fits all” is a sound philosophy for system designers to follow, it poses multiple challenges for application developers and system administrators. It can be hard for an application developer to pick one system when the needs of her application match the features of multiple “one size” systems. The choice becomes considerably harder when different components of an application ...

this experiment was conducted to determine the reproductive performance of kurdi ewes which were artificially inseminated (ai). in total 240 kurdi ewes, weighing 49.5±2.5 kg were used in the trail. the ewes were allocated randomly to one of four groups (n=60/in each group). for synchronizing, controlled internal drug release (cidr) was placed in the vagina of all individuals for 14 days. after ...

The efficiency of a short-term treatment with an intravaginal device containing progesterone (CIDR) combined with pregnant mares’ serum gonadotrophin (PMSG) and prostaglandin analogue (PGF2α) was evaluated for the induction of estrus, initiation of cyclic activity, and fertility in postpartum suckled yak cows. Seventy-five postpartum suckled yak cows were assigned to three treatments: (1) inser...

This study evaluated the effects of systemic progesterone concentration on oocyte quality and in vitro embryo production. Oocytes were retrieved from 15 crossbred cows (Bos taurus x Bos indicus). These cows were randomly allocated into three groups to provide low; high, or very low (LP4, HP4 and VLP4, respectively) plasma progesterone concentrations and received either a previously used CIDR, t...
