Crespilho, André Maciel; Chiaradia, Livia; Cortez, Adriana; Dinelli, Marcela; Papa, Frederico Ozanam [UNESP]; Gomes, Gustavo MendesMade available in DSpace on 2022-04-30T04:22:58Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-01-01; Sperm concentration is traditionally evaluated by counting cells in a hemocytometric Neubauer chamber, often a highly subjective, time-consuming, and laborious technique prevalent in andrology laboratories around the world. However, the Computer-Assisted Semen Analysis (CASA) represents a more consisten...

Crespilho, André Maciel; Bosco, Karinne Ávila; Dell’aqua, Camila de Paula Freitas [UNESP]; Segabinazzi, Lorenzo Garrido [UNESP]Made available in DSpace on 2022-04-30T14:24:48Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-10-25; Protocols for cooling or freezing goat semen usually recommend centrifugation for seminal plasma removal. However, little is known about the effect of this process on goat sperm viability and functionality. The present study evaluated the effects of centrifugation force on the plasma membrane, acrosomes...
Does bull temperament impact growth performance and semen quality?
Braz, Karoline Maria Gil; Monteiro, Fabio Morato; Fernandes, Luana Gomes [UNESP]; Rodrigues, Naiara Nantes [UNESP]; Peixoto Jr, Kléber da CunhaMade available in DSpace on 2020-12-12T01:21:50Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-06-01; The aim of this study was to evaluate the influence of temperament on body weight and reproductive performance of Nelore bulls. Temperament of 24 young bulls was assessed by chute score (CS) and flight speed (FS). Based on the results of two consecutive evaluations (M1 and M2), bulls were divided into t...
Action of cholesterol-loaded cyclodextrin on viability of ram semen
Marques Silva, Juliano Pianowski; De Almada, André Felipe Berto; De Lima, Jonathan Soares; De Freitas Guaitolini, Carlos Renato; Crespilho, André MacielMade available in DSpace on 2020-12-12T01:31:59Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-01-01; Background: Studies report that cyclodextrins have the property of carrying cholesterol to the membrane, but in some cases can also remove this cholesterol from the plasma membrane. The mechanism of action of CLC is not well understood, however, it seems to involve sperm protection during the freezing a...
Can cover sheath model influence semen retention in AI-gun trials and pregnancy...

Crespilho, André Maciel; Bosco, Karinne Ávila; Dell'Aqua, Camila de Paula Freitas; Segabinazzi, Lorenzo Garrido; Papa, Frederico OzanamProtocols for cooling or freezing goat semen usually recommend centrifugation for seminal plasma removal. However, little is known about the effect of this process on goat sperm viability and functionality. The present study evaluated the effects of centrifugation force on the plasma membrane, acrosomes, and DNA integrity of goat semen. Four ejaculates from each of the four different Anglo Nubian male goats wer...
Effect of the Flunixin Meglumine on Pregnancy Rates in an Equine Embryo Transfe...
Okada, Carolina Tiemi Cardoso [UNESP]; Segabinazzi, Lorenzo Garrido [UNESP]; Crespilho, André Maciel; Dell'Aqua, José Antônio [UNESP]Made available in DSpace on 2018-12-11T17:36:27Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-03-01; During the equine embryo transfer (ET), manipulation of the recipients cervix can stimulate the release of prostaglandin F2α by the uterine environment. Nonsteroidal anti-inflammatory drugs such as flunixin meglumine (FM) are frequently used in order to prevent a potential luteolysis. However, despite t...
