1. Effect of glycerol, n, n-dimethylformamide and n-methyl-2-pyrrolidone on rabbit sperm stored at 4 °C and 16 °C
Abstract Artificial insemination with cooled semen is the most common practice in rabbit farms and any improvement on it helps to increase the efficiency and productivity of rabbit meat farms. Therefore, the aim of this study was to assess whether different cryoprotectant agents (CPA) as glycerol, N, N-Dimethylformamide (DMF) and N-Methyl-2-Pyrrolidone (NMP)

2. Assessment of viability of sperm cells of Litopenaeus vannamei on cryopreservation
Aiming at assessing the cryopreservation potential of Litopenaeus vannamei sperm cells, 74 spermatophores were manually extracted from the sexually mature individuals. After the toxicity test to define the cryoprotectant concentration, suspensions of spermatic cells were cryopreserved in the groups in freezing solutions comprising different cryoprotectants s

3. 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

4. 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

5. Efeito de meios de re-diluição pós-descongelação sobre a cinética e morfologia de espermatozóides caprinos congelados em meio à base de água de coco em pó (ACP-101) ou TRIS. / Effect of means of re-diluted post-thaw on the kinetics and morphology of frozen goat spermatozoa through the base of coconut milk powder (ACP-101) or TRIS.
O trabalho teve como objetivos: avaliar in vitro o sêmen caprino congelado nos meios diluentes à base de água de coco em pó (ACP-101) e TRIS (hidroxi-metil amino metano); analisar o efeito de soluções para re-diluição seminal pósdescongelação por meio de parâmetros cinéticos mensurados pelo sistema Sperm Class Analyser e; comparar a eficiência

6. 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
