Forty-two mares were randomly assigned in a 3 x 2 factorial experiment which included three intervals between rectal palpation (6/6h, 12/12h and once a day palpation) and two frequencies of inseminations (daily or every other day). The mares were inseminated with semen from only one stallion, diluted in minimal contamination extender. There were no differences in the conception rate at first cycle, conception/cycle, conception total, efficiency of pregnancy in either system of rectal palpation, independently of the frequency of insemination utilized. Also there were no differences among intervals of rectal palpation concerning the following reproductive characteristics: number of cycles/mare, cycles/pregnant mare, cycles/ pregnancy, pregnancy/cycle, number of inseminations/mare, inseminations/ pregnant mare and insemination/open mare. There were no differences in pregnancy rate at first cycle, pregnancy rate/cycle, pregnancy rate total and efficiency of pregnancy between the two frequency of insemination. However, the frequency of insemination influenced the number of inseminations/mare, number of inseminations/ pregnant mare and inseminations/open mare. The highest values were observed with the mares inseminated daily. Therefore, insemination every other day can be recommended. If necessary the mare may be palpated rectally at intervals of six hours without reducing the pregnancy rate.

The stroke, cause of morbidity and mortality, has been associated with imbalance in the neural control of the heart, which contributes to the decrease in heart rate variability (HRV) and a prognostic factor for cardiacevents and arrhythmias. The aim of this study was to in investigate the autonomic modulation of heart rate of men suffering from lesions stroke in chronicphase. Eight menaged 58.62 ± 2.88 years, 27.41 ± 5.33 kg/m2of bodymass índex, with paresis for at least six months were studied. Heart rate (HR) and RR intervals (iR-R) were recorded at rest in supine position for 10 minutes. Geometric índices of the Poincaré plot were calculated: SD1, associatedwith vagal activity; SD2, associated with global activity but sympathetic predominance, and the relationship of both (SD1/SD2). Geometric index values in the sample: SD1 = 20,54 ± 9,90ms; SD2 = 36,80 ± 30,61ms; SD1/SD2 = 0,49 ± 0,04. The reference values from literature for healthy subjects are: SD1 = 19.6 ± 9.4ms e 22.8 ± 16.1 ms; SD2 = 43.2 ± 17.7 ms e 56.3 ± 12.3 ms; SD1/SD2 = 0.49 ± 0.21ms. Men in chronic phase of stroke haven't autonomic dysfunction analyzed by nonlinear method – Poincaré geometricíndices.
