________________________________________________________________________________ Abstract The aim of the study was to determine if the breeding potential of 25-month old Bonsmara beef bulls could be predicted from production characteristics. Forty-one Bonsmara bulls were included in an on-farm performance test (also known as the Phase D growth test) for a period of 180 days. At an average age o...

AIM The study was conducted at Artificial Breeding Research Centre, NDRI, Karnal, to determine the sexual behavior and its relationship with semen quality parameters in Sahiwal breeding bulls. MATERIALS AND METHODS A total of 63 ejaculates were collected from six adult Sahiwal bulls (age ~47 mo and bwt ~466 kg), to study the relationship of sexual behavior and semen quality. The degree of ass...

OBJECTIVE To assess the relative effects of individual testosterone products among hypogonadal men. DESIGN Systematic review and network meta-analysis. METHODS We searched MEDLINE, Embase, Cochrane CENTRAL, and grey literature (25 May 2017) for randomised-controlled trials (RCTs) and non-randomised studies (NRS) that involved hypogonadal men given testosterone replacement therapy (TRT) for ...

CONTEXT The relationships between testosterone dose and its effects on sexual function, mood, and visuospatial cognition are poorly understood. OBJECTIVE To elucidate testosterone dose-response relationships in older men, we examined the effects of graded testosterone doses on sexual function, mood, and visuospatial cognition in healthy, older men (age, 60-75 yr). SETTING This study was per...

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 ...

OBJECTIVE To conduct a systematic review and meta-analysis of randomized placebo-controlled trials to measure the effect of testosterone use on sexual function in men with sexual dysfunction and varying testosterone levels. METHODS Librarian-designed search strategies were used to search the MEDLINE (1966 to October 2004), EMBASE (1988 to October 2004), and Cochrane CENTRAL (inception to Octo...

INTRODUCTION Both clomiphene citrate (CC) and testosterone supplementation therapy (TST) are effective treatments for men with hypogonadism. We sought to compare changes in symptoms and treatment efficacy in hypogonadal men before and after receiving CC and TST. PATIENTS AND METHODS 52 men who received TST and 23 men who received CC for symptomatic hypogonadism were prospectively followed for...

To determine the effect of low protein intake on boar libido, semen characteristics, and plasma hormone concentrations, 20 crossbred boars (1 yr of age) were divided into 10 littermate pairs, and boars from within pairs were fed 44 g/kg of BW.75 per day of either a low-protein diet (7% CP) or a control diet (16% CP) with the same energy content (3.41 Mcal of ME/kg). During the first 16 wk and f...

BACKGROUND Trypanosomiasis is a disease caused by Trypanosoma (Dutonella) vivax, a hemoprotozoa that can affect bovines. In South America, the sanguineous form is mechanically transmitted from one mammalian host (ruminant) to another by the bite of a blood-sucking insect or by needles contaminated with infected blood. The negative impact of the parasitosis caused by T. vivax infection on the re...
