Abstract

Alguns aspectos biométricos do aparelho genital externo de jumentos doadores de sêmen da raça PêgaSome biometric aspects of the external genital tract from donkey Pêga breed semen donors RESUMO Pêga, com peso médio de 272±34, de 7,4 (5,9 a 9,6), e o VT esquerdo foi de 155,5±14,4mL, enquanto o direito foi de 149,3±14,9. A medida de FUND foi de 25,3±3,3mm (20,3a 30,8mm) (TH -dorso ventral) and thickness of spermatic funiculum (FUN -third part). The biometric data from biometric testis were used to calculate the testis indices (TI) and testis volume (TV). The TI observed was 7.4 (5.9 a 9.6) and TV was 155.5±14.4, 149.3±14.9 respectively left and right. The average FUN was 25.3±3.3mm (20.3 a 30.8mm) O presente estudo foi conduzido com seis jumentos reprodutores da raça altura testicular (AT -dorso ventral), largura testicular (LT -médio lateral) e espessura do funículo (FUNterço médio). Os dados de biometria testicular foram utilizados para o cálculo do índice testicular (IT) e volume testicular (VT). O IT médio observado foi Palavras-chave: biometria, volume, índice testicular. ABSTRACT The present study was performed with six Pêga breed donkeys, weight from 231 to 326kg (272±34.9). The breeders were divided into the adult group (J1, J2 e J3, 15 years old average) and the young group (J4, J5 e J6, 3.5 years old average). . The donkeys presented normal rates of fertility

Evaluation of hypo-osmotic swelling test and supra vital staining technique as indicators for donkey semen freezability

“…Our results from raw semen (Table 1) were not different from the others researchers who obtained similar values to volume, motility and strengh (Morais et al 1994, Canisso et al 2009, Canisso et al 2011, Rota et al 2012and Madison et al 2013.The minimum requirement for fresh semen motility prior to freezing is above 60 %, because after freezing and thawing a reduction of 30 % to 40 % in total motility values of fresh semen, and the minimal post thawed motility must be at least 30 % (CBRA 2013).…”

“…In respect of sperm morphology, the average of major and minor defects found (Table 1) was higher compared to values reported by Canisso et al (2009Canisso et al ( , 2011, Morais et al (1994), who found a mean of (7.0 ± 3.0 %), (8.5 ± 2.1%) for major defects, and (7.0 ± 4.0 %) and (7.0 ± 2.6 %) for minor defects respectively. This can be explained by the small number of animals that the cited authors have worked with.…”

Immunocastration in donkeys: clinical and physiological aspects

“…The experiment was performed from June to October of 2015, in São José de Mipibú, Rio Grande do Norte state, Brazil, that displays latitude 6° 4' 22'' south, longitude of 35° 14' 6'' west and altitude of 49 meters. A total of 12 male donkeys from the Northeast breed were selected, with age from 5 to 7 years (Mean and Standard Deviation), weight varying from 108 to 120 kg, after clinical andrological exam as recommendations by Canisso et al (2009). Animals were vaccinated against rabies, encephalomyelitis, influenza, and tetanus.…”

Vascularização uterina de éguas prenhes de jumento e de garanhão monitoradas por ultrassonografia Doppler

“…Segundo Blanchard & Taylor (2005), os asininos e muares (produtos híbridos do cruzamento entre asininos e equinos) estão desfrutando de crescente popularidade como animais de estimação e animais de trabalho. Canisso et al (2009) confirmam essa informação ao afirmarem que, no Brasil, tem havido grande interesse em jumentos com especial foco na doação de sêmen para a produção de muares, embora existam no país plantéis asininos de elevado padrão genético, onde o reprodutor é utilizado para a melhoria zootécnica da própria espécie.…”
