13. Comportamento sexual, parâmetros seminais e diluição pós-congelamento de sêmen de jumentos (Equus asinus) da raça Pêga / Sexual behavior, seminal parameters and dilution after freezing Pêga breed donkeys (Equus asinus) semen
The aim of this study was to elucidate aspects of asinine behavior from the description of various collections using an artificial vagina and relate this behavior with the seminal parameters. We evaluated also the availability of the formulation of the diluent T2-94 plus dimethylformamide in the protection of sperm cells during cryopreservation of semen from

15. Insulin addition to swine semen diluted and cooled at 15 ºC
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

17. Reproductive characteristics of captive greater rhea (Rhea americana) males reared in the state of São Paulo, Brazil
Rheas (Rhea americana) belongs to the ratite group. Considering the commercial significance of this birds, some techniques, such as semen collection, were standardized. In this study, 107 male rheas (3 to 4 years of age) reared in commercial farms in the state of São Paulo, Brazil, were used. Semen was collected during the breeding and off-breeding seasons

18. Cigarette smoking impairs sperm bioenergetics
OBJECTIVE: The growing consensus on the negative impact of cigarette smoking on fertility prompted us to compare the rate of sperm respiration in smokers and non-smokers. MATERIALS AND METHODS: Semen samples from 20 smokers and 58 non-smokers consulting at the andrology laboratory for fertility evaluation were used. Smoking was defined as consumption of at l

20. Efeito do tratamento com antioxidantes na qualidade de espermatozóides criopreservados de cães / Effect of antioxidants on post-thaw canine sperm quality
One of the main factors known to impair post thaw semen quality is oxidative stress (i.e., higher production of reactive oxygen species not compensated by improved antioxidant protection). The present experiment aimed to evaluate the effects of antioxidant treatment with glutathione (GSH) and vitamin E on the quality of dogs cryopreserved semen. Towards this

21. Avaliação andrológica e criopreservação de sêmen de pumas (Puma concolor Linnaeus, 1771) adultos / Andrologic evaluation and cryopreservation of adult cougars (Puma concolor Linnaeus, 1771) semen
The wild felines is one of the most endangered species of the world and its population is affected by some factors that vary geographically because of the alduteration of their habitat, food available, strong hunt pressure or even the low population density. Assisted reproduction techniques such as gametes cryopreservation and in vitro fertilization are fund

22. Avaliação do sêmen ovino diluído e congelado em meio à base de água de coco em pó (ACP-102c) ou Tris. / Evaluation of sheep semen diluted and frozen in the middle of the base of coconut milk powder (ACP-102C) or Tris.
The cryopreservated semen at artificial insemination programs is a value tool for genetic and ovine breed conservation programs. To facilitate the disponibility of seminal extenders and reduce the costs, it was developed a vegetal extender based on powder coconut water (PCW- 102), that shown satisfactory results in chilled ram semen. However, there is a lack

24. Protein profile of swine seminal plasma and its association with quality of frozen semen / Perfil protéico do plasma seminal de suínos e sua associação com a qualidade do sêmen congelado
Artificial insemination (AI) in swine with frozen semen presents lower reproductive performance than AI with cooled semen. Such inefficiency can be attributed to many factors, especially to the semen extenders and individual boar effects, since boars may have different protein content in their seminal plasma. The objective of this study was to evaluate the p
