1. Effect of adenosine concentration on quality of cooled ram semen
ABSTRACT This study analyzed the adenosine concentration on quality of ram semen in different refrigerated storage times at 5 °C. The design was in blocks with repeated-measures factorial design. Five levels of adenosine and four refrigeration times were considered as fixed effects and the animal as random effect (block). Ram semen was diluted with Andromed

2. Storage of boar semen at 16-18 °C in the long-term commercial extender prepared with deionized water or nanowater
Abstract The aim of this study was to assess the usefulness of nanowater (NW; water declusterized using cold plasma treatment) as a diluent for a commercial boar semen extender during the 15-day storage (Days 1 to 15) at 16-18 °C. Ejaculates collected from 8 boars were subjected to the standard evaluation and then diluted in the extender prepared with deion

3. Concentration of soybean lecithin affects short-term storage success of goat semen related with seminal plasma removal
Abstract The objective of this study was to investigate the need of seminal plasma removal for short-term cooling of buck semen in soybean lecithin (SL) based extender. Each pool was divided equally, and one half was subjected to centrifugation to remove seminal plasma (SP-), while the other half remained with seminal plasma (SP+). Then, both SP+ and SP- sam

4. 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)

5. Addition of chlorogenic acid and caffeine during the processing of cooled boar semen
RESUMO O objetivo deste estudo foi avaliar os efeitos da adição de ácido clorogênico (ChA) antes do resfriamento e sua combinação com cafeína adicionada durante o reaquecimento sobre a qualidade do sêmen suíno resfriado. Dez ejaculados foram diluídos em diluidor comercial com adição ou não de 4,5mg/mL de ChA e armazenados a 15°C. Após zero, 24

6. The effects of xanthan gum on equine sperm quality during cooling storage
RESUMO Esse estudo foi desenvolvido para avaliar os possíveis benefícios de acrescentar xanthan gum a um extensor padrão através de analises in vitro de qualidade de esperma. Semen foi coletado quatro vezes de cinco garanhões diferentes (n = 20 amostras) e submetido a armazenamen to resfriado em diferentes condições: controle (apenas extensor padrão)

7. Histochemical study of the oviducal gland and analysis of the sperm storage tubules of Mustelus schmitti Springer, 1939 (Chondrichthyes, Triakidae)
Abstract: The paired oviducal glands of immature and mature females of Mustelus schmitti were examined macro and microscopically. Findings indicate that these glands possessed the same zonation as in most chondrichthyans from anterior to posterior: club, papillary, baffle and terminal zones. The whole gland is composed by simple tubular glands that connect w

8. Osmolality and composition of the extender during the cold storage of Prochilodus lineatus (Characiformes: Prochilodontidae) sperm
Neste trabalho avaliou-se os efeitos da osmolalidade e da composição do diluidor no sêmen de Prochilodus lineatus, após o resfriamento. O sêmen foi diluído em seis diluidores: duas composições (água de coco em pó(r) = ACP; Beltsville Thawing Solution(r) = BTS) x três osmolalidades (285, 325 e 365 mOsm/kg) mais uma alíquota sem diluição como con

9. Development of single tubing-type canister for cryo-storage of bull semen and their effect on sperm motility and viability
The objective of this study was to evaluate the potential of using single tubing-type canister on sperm quality. Semen was collected from the Bali cattle bull by electroejaculation technique and was cryopreserved in liquid nitrogen using slow freezing cryopreservation method. Two type of canister volume was used in this study; commercial canister (342.25π x

10. 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

11. Viability of bull spermatozoa collected from the epididymis stored at 18-20°C
The aim of this study was to evaluate the viability of bull spermatozoa collected from the cauda epididymis stored at 18-20°C, which were compared with semen collected by electro-ejaculation method and preserved at 5°C. Ten pairs of testes from Tabapuã bulls were removed by orchiectomy and stored for 6 (G6), 12 (G12), 18 (G18), 24 (G24) and 30 (G30) h at

12. 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
