KOYUNCU, M. and S. OZIS ALTINCEKIC, 2013. Testicular development and body growth in prepubertal ram lambs of Kivircik, Karacabey Merino and Tahirova in South Marmara region of Turkey. Bulg. J. Agric. Sci., 19: 152157 An experiment was conducted to compare testicular diameter (TD), testicular length (TL), scrotal circumference (SC), scrotal length (SL) and body weight (BW) gain of 150 ram lambs ...

Data from 528 male and 645 female progeny of 63 sires were used to estimate genetic correlations between female and male reproductive traits. Data were from two Hereford herds involved in a long-term selection program of the North Carolina Agricultural Experiment Service. Testicular measurements of circumference, diameter, length and volume were obtained on bulls at 205 and 365 d. Testicular gr...

This study was designed to determine the testicular abnormalities in rams slaughtered Sokoto, Nigeria. The testicles of presented for slaughter were examined, and age, breed, position, sites noted. Out 638 3 had abnormalities, representing a prevalence 0.47%, comprising 2 (0.31%) unilateral cryptorchidism 1 (0.16%) hypoplasia. (0.58% (2/342) 0.34% (1/296) obtained at Sokoto metropolitan abattoi...

Independent of whether natural mating or artificial insemination is used for breeding, libido (sex drive) is evidently crucial to reproductive competence in all male meat animal species. Breeding goat bucks vary in their levels of libido; therefore, there is a need for the development of a predictive standardized test for estimating sex drive. The objective of this study was to evaluate libido ...

The aim of the present study was to determine seasonal variations in semen characteristics, testicular size, and plasma testosterone concentration in Iranian Khalkhali goats. An artificial vagina was used to collect semen from 10 bucks (2–4 years of age), from November 2013 to October 2014. Testicular circumference was higher (P<0.05) from September to October. Ejaculate volume, sperm ...

Testicular fine needle aspiration cytology (FNAC) is widely being used in humans to evaluate the functional testicular mechanism, but its application is very limited in animals especially breeding bulls. This preliminary study was conducted to assess the effect of testicular fine needle aspiration (FNA) technique on testicular biometry and seminal characteristics in Karan Fries crossbred bulls....

Records of body weight and testicular measurements (scrotal circumference, scrotal length and average testes weight) were obtained from 296 (197 Red Sokoto and 99 Borno White) indigenous goats of various ages (between one and three years of age) in Nigeria. Red sokoto goats had significantly (P<0.05) higher body weight than the Borno White. The Borno white had significantly (P<0.05) longer scro...

The objective was to determine the effects of a recombinant fusion protein anti-GnRH vaccine on testicular development, feedlot performance, and carcass quality of beef bulls. Crossbred beef bulls (n = 58, average weight 306 kg, 9 mo of age), were randomly allocated to two groups and received either an anti-GnRH vaccine (GnRH) or placebo (Control) by intramuscular injection on d 0, 56, and 112....

Mechanisms of testicular thermoregulation, the relationship of scrotal, testicular vascular cone (TVC), and testicular morphology with thermoregulatory capability, and their effects on semen quality and sperm production were studied in 20 Bos indicus, 28 crossbred, and 26 Bos taurus bulls. The ratio of testicular artery length and volume to testicular volume were larger (P<0.05) in B. indicus a...

The body weight and testicular and epididymal parameters of Afar, Long-eared Somali (LES), and Woyto-Guji (WG) breeds of goat were investigated. A total of 405 randomly selected bucks of Afar (n = 135), Long-eared Somali (n = 135), and Woyto-Guji (n = 135) were included in this study. The overall mean scrotal circumference (SC), testicular volume (TV), testicular length (TL), testicular weight ...
