We evaluated sexual behavior of St. Croix White (SC; n = 5) and Barbados Blackbelly hair (BB; n = 4) rams under two environmental conditions in the tropics. Sexually naive rams were individually exposed for 15 min to a restrained, ovariectomized ewe, three times during a 3-wk period in June, in a pen with shade (SHADE; 33.1+/-.3 degrees C) or without shade (SUN; 38.3+/-.3 degrees C). Rectal tem...

With the trend of SOC technology, high density and high capacity embedded memories are required for successful implementation of the system. In modern SOCs, embedded memories occupy the largest part of the chip area and include an even larger amount of active devices. As memories are designed very tightly to the limits of the technology, they are more prone to failures than logic. Thus, memorie...

Intense intrasexual competition between males often results in the establishment of a dominance hierarchy, promoting differential access to females. Dominant males are expected to evolve more prudent sperm allocation strategies, whereas subordinate males are expected to counteract their mating disadvantage by increasing their sperm allocation. Burying beetles, insects that breed on small verteb...

Profiles of LH and FSH levels and pituitary LH responses to exogenous luteinizing hormone releasing hormone (LHRH) have been characterized in rams, castrated rams (wethers), and wethers implanted with testosterone. Rams were castrated when adult, and, at the time of castration, two groups of wethers were implanted with either four or eight testosterone capsules. Rams showed random pulses of LH ...

The preponderance of large-scale healthcare databases provide abundant opportunities for comparative effectiveness research. Evidence necessary to making informed treatment decisions often relies on comparing multiple options outcomes interest observed in a small number individuals. Causal inference with treatments and rare is subject that has been treated sparingly the literature. This paper d...

Objectives were to estimate effects of sire breed (Dorset, Finnsheep, Romanov, Texel, and Montadale), dam breed (Composite III and northwestern whiteface), mating season (August, October, and December), ewe age (1, 2, and 3 yr), and their interactions on reproductive traits of F1 ewes. A total of 1,799 F1 ewes produced 3,849 litters from 4,804 exposures to Suffolk rams during 35-d mating season...

This research was carried out to investigate the effects of different organic feeds (1. Traditional barley (control), 2. Organic (OB), 3. triticale (OT)) and 4. corn (OC) on reproductive performance in Karayaka sheep. Trial were given from 20 days before mating with rams 10 after added pasture period The animals used experiment 3-4 years old, their average live weight 56±0.5 kg, heads each tria...

I tested the effects of male body size on male mating behavior and reproductive success in the western mosquitofish, Gambusia affinis. In two separate behavioral experiments (male–male competition and no-competition), I tested the predictions that (1) larger males out-compete smaller males for mates and (2) small males increase their number of mating attempts in the absence of a larger competit...
