| ABSTRACT The aim of this study was to assess the sperm quality and testicular histomorphometry of Wistar rats supplemented with extract and fractions of fruits of Tribulus terrestris L. The ethanolic extract was obtained by dynamic maceration of spray-dried fruit. This extract was fractionated by liquid-liquid partition, using increasing polarity solvents. Twenty male rats were separated in four groups, with five rats in each group. The control was supplemented with distilled water, while the others were daily given the ethanolic extract, hexanic or aqueous fraction soluble in methanol in a dose of 42 mg.kg-1.day-1 for 70 days. Sperm was obtained from the right epididymal tail for the analysis of motility, count, morphology and viability. The testicular... |

| The objective of this study was to evaluate the effect of adding different doses of insulin to swine semen processed and stored at 15 ºC. The experiment used sixteen ejaculates from four commercial breeding pigs, distributed in a randomized block design (ejaculate) with split plot along time (0, 24, 48 and 72 hours of storage) with four treatments (insulin levels - 0.0 4.0 8.0 and 12.0 IU per dose) and 16 repetitions. The experimental unit was made of two insemination doses of 100 mL each, with 3×10(9) spermatozoids. Insulin used was NPH-human, added at the time of processing the doses. The addition of insulin did not affect motility, sperm viability, the percentage of abnormal cells, the osmotic resistance or the degradation rate of motility in 120... |
