1. USO DE DILUENTES ALTERNATIVOS A BAIXAS TEMPERATURAS NA MANUTENÇÃO DA QUALIDADE ESPERMÁTICA DO SÊMEN SUÍNO / USE OF ALTERNATIVE SOLVENTS AT LOW TEMPERATURES IN THE MAINTENANCE OF SPERM QUALITY OF SWINE SEMEN
Countless studies have been conducted with the purpose of improving the conservation of boar semen, either with the use of diluents or alternative temperature ranges, or adding antioxidants or amino acid to the diluent. The present study aimed to define an alternative diluent and temperature preservation of boar semen and evaluate the effects of adding trolo

2. Uso de análise multivariada para determinar a associação do desempenho reprodutivo de machos suinos com as caracteristicas seminais / Use of multivariate analyses to determine the association of boar fertility with semen traits
The application of new approaches that measure certain sperm motion characteristics and their association with boar fertility has shown a recent increase. Computer-assisted semen analysis (CASA) offers standardized assessment of multiple sperm motion parameters and it is plausible that the combination of these parameters with morphological sperm defects may

3. Inseminação artificial em ovinos.
ABSTRACT: The aim of this review is to show and illustrate an way clear and objective of the aspects involved in the artificial insemination in sheep. In this species the potential is great, therefore it is early in its productive and reproductive aspects, with eminence to the short interval between generations. In the program of artificial insemination (AI)

4. Métodos alternativos para análises da capacidade de ligação dos espermatozóides caprinos / Alternatives methods for analysis of the goat sperm binding Capacity
This study aimed to carry out the analysis using the simple binding of goat sperm to bovine oocytes and to the perivitelline membrane of the hen s egg yolk compared to binding to the goat oocytes, looking for an alternative to predict the buck semen quality without losing the precision and accuracy of their own oocytes. Sixteen doses of goat semen were colle

5. Effects of the overshadow availability at pasture on the reproductive characteristics in Nelore Bulls / Efeitos da disponibilidade de sombra na pastagem sobre as características reprodutivas de touros da raça Nelore
It is known that heat stress is the main cause that affects bulls reproductive performance, consequently leaded to testicular degeneration. This pathologic alteration can also occur in Bos Indicus cattle. The objective of this experiment was verify the shadow availability effect at pasture on reproductive characteristics in Nelore, a Bos Indicus bull. For th

6. 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

7. Fatores de risco para a contaminação bacteriana durante a coleta do ejaculado suíno e suas consequências sobre a qualidade das doses inseminantes / Risk of factors for bacterial contamination during boar semen collection and the consequences on the quality of extended semen doses
O objetivo do presente estudo foi verificar a influência de diferentes pontos de risco de contaminação bacteriana durante a coleta do ejaculado suíno e seus efeitos sobre a qualidade da dose inseminante (DI). O experimento foi realizado em quatro centros de difusão genética (CDG), nos quais as coletas dos ejaculados foram observadas buscando possíveis

9. Enzymatic antioxidant activity and resistance against the oxidative stress in semen of captive partridges (Rhynchotus rufescens) supplemented with selenium / Dosagem dos níveis de anti-oxidantes enzimáticos e resistência celular ao estresse oxidativo, do sêmen de perdizes (Rhynchotus rufescens) criadas em cativeiro e suplementadas com selênio
Considerando a importância comercial da perdiz (Rhynchotus rufescens), implantou-se algumas biotecnologias reprodutivas. Trinta animais foram divididos aleatoriamente em dois grupos: controle (sem selênio orgânico) e tratamento (com 0,2 a 0,8mg de selênio em 1000kgs de ração ), provenientes da FCAV-UNESP/Jaboticabal (2007-2008). Coletou-se semên por e

10. Use of propolis and ascorbic acid on goat semen cryopreservation / Uso da própolis e do ácido ascórbico na criopreservação do sêmen caprino
The objectives of this study were to verify if the propolis and ascorbic acid contain effect on plasmatic membrane integrity of goats spermatozoa as well as investigate the potential of these antioxidants on the use of goats spermatozoa cryopreservation extenders. Semen from five adults goats were used, totalizing 5 semen samples for each one. After semen co

11. Colheita, análise e criopreservação de sêmen de uma espécie modelo de primata neotropical, Sagui-de-Tufo-Branco (Callithrix jacchus) / Collection, analysis and cryopreservation of semen from a model species, the common marmoset (Callithrix jacchus)
The Callithrix jacchus can be used as a model species for other Neotropical primates species, mainly Callithriquids, for reproductive studies. Semen samples were collected with the following objectives: to improve the penile vibrostimulation technique, validate sperm evaluation techniques for field work, analyse the semen characteristics from animals at 2 co

12. Criopreservação de sêmen de galos / Roosters sperm cryopreservation
Adding extenders to poultry semen is currently used in artificial insemination programs to optimize the management of genetically superior males. Fresh semen fertility usually declines after 1 hour of collection, raising the need to use diluents and low temperatures to store semen for longer periods. Low density lipoprotein (LDL), extracted from the egg yolk
