egg yolk is the most commonly used cryoprotective agent for sperm cryopreservation of several species.the objective of this experiment was to compare the effectiveness of egg yolk from four avian species(domestic chicken, duck, turkey and pigeon) on sperm quality following cryopreservation of the ram semen.ejaculates were collected, using an electroejaculator, from six fertile rams. samples wer...

the effect feeding olive-pulp silage (ops) for 120 days on several blood attributes was studied using 16 rams allotted to two diets consisting of 70% corn silage or 70% ops. olive-pulp silage feeding resulted in lower serum total protein, alanine aminotransferase, calcium and phosphorus levels and higher glucose concentration compared to the corn silage diet. body weight and other blood attribu...

the present study investigated the possibility of replacing salamon with modified shotor diluent (msd) and egg yolk (ey) with low density lipoprotein (ldl) for chilled storage of ram semen. good quality semen (>80% progressive forward motility (pfm) of sperm) from 3 fertile rams was collected using an artificial vagina and pooled for each experiment. low density lipoprotein was extracted from f...

In songbirds song production requires the intricate coordination of vocal and respiratory muscles under the executive influence of the telencephalon, as for speech in humans. In songbirds the site of this coordination is suspected to be the nucleus retroambigualis (RAm), because it contains premotor neurons projecting upon both vocal motoneurons and spinal motoneurons innervating expiratory mus...

We take an important step forward in making Oblivious RAM (O-RAM) practical. We pro-pose an O-RAM construction achieving an amortized overhead of 20 ∼ 35X (for an O-RAMroughly 1 terabyte in size), about 63 times faster than the best existing scheme. On the theoreticfront, we propose a fundamentally novel technique for constructing Oblivious RAMs: specifi-cally, we partition a bi...

For 6 years adult, non-synchronized Hampshire ewes (n=2,5,8,8,9 and 12) and rams (n=6,10,12,11,11 and 9) were maintained separately and released to contiguous pastures having in common a woven-wire fence about 80m long and 1.1m high. Natural estrous cycles were monitored daily by observations of ram-seeking behavior as defined as a ewe being persistent in staying at the common fence with attent...
