Abstract:

The scrotal-testicular biometry was evaluated in goats raised in Piaui state, Brazil, presenting different levels of scrotal division, in rainy and dry periods of the year. For this study, eighteen male goats at mating age were accomplished and arranged into three groups (6 animals each), obeying the classification as goats with no scrotal bipartition (GI), goats showing scrotal bipartition up to 50% of testicular length (GII), and goats with more than 50% of scrotal bipartition (GIII). The biometry of the scrotal-testicular was made evaluating the scrotal length (SL), scrotal circumference (S

Abstract:

Bovine antisperm antibodies (ASAs) have been associated with teratospermia and asthenospermia. It was hypothesized here that scrotal insulation induces the formation of ASAs and deterioration of sperm function. Scrotal insulation bags were placed in 10 bulls for 8 days. Semen was collected on days −29, −22 and −2, twice weekly from days 5 to 54, and thereafter weekly until day 96 (day 0 = first day of scrotal insulation). On each collection day, scrotal circumference, sperm motility, morphology, membrane integrity, acrosome integrity, apoptosis, lipid peroxidation, mitochondrial membrane poten

Abstract:

The present study investigated the serum testosterone profile of Marwari stallions before and after exposure to a mare and the relationship of serum testosterone profile with scrotal circumference, semen characteristics, reaction time, stallion age, bodyweight, and height. Marwari stallions (n=9) of three age groups (2-4 years, n=3; 4-6 years, n=3; and 6+ years, n=3) were used in the study. Scrotal circumference, height, and bodyweight of each of the stallions were measured. Semen was collected from each stallion twice per week in the early-morning hours using an artificial vagina and a mare i

Abstract To find an in vitro predictor of in vivoM/em&gt; semen motility prompted this study. Our objective was to evaluate semen motility for an 8-hour period immediately following a breeding soundness exam. Ejaculates from 52 Angus and 56 Charolais bulls were evaluated. Motility, morphology, scrotal circumference and pH of ejaculate were evaluated at the time of collection. Ejaculates were then extended using a one to one ratio and incubated in a water bath held at 37 degrees Celsius and evaluated hourly. Motility was evaluated hourly for 8 hours, or until motility of the sample reached

Abstract Background: Injection of alloplastic material underneath the penile skin for penile augmentation causes many complications such as inflammation, infection, ulceration, and pain during sexual activity. One of the treatments for complications after these penile augmentation procedures is surgical excision of the foreign body granuloma followed by penile skin coverage with bilateral scrotal flaps. There are no prior prospective studies published about anatomical and functional outcomes. Objective: To study the anatomical and functional outcome of one-stage bilateral scrotal flap reconstr

Abstract The objective of this study was to determine if oral meloxicam (M; a nonsteroidal anti-inflammatory drug) administered at castration to pre-weaning age calves affected average daily gain (ADG) or behavior. Prior to castration (d −14), Angus bulls were weighed and randomly assigned to be band castrated (BAN; n = 8; age = 90.2 ± 6.5 d; BW = 146.3 ± 11.4 kg; scrotal circumference = 16.0 ± 0.5 cm) or castrated with M (BAN + M; n = 9; age = 102.1 ± 6.2 d; BW = 146.0 ± 7.7 kg; scrotal circumference = 16.1 ± 0.3 cm).

Abstract:

The polymorphism of the bovine growth hormone gene (bGH) was studied in 211 Nellore pure breed males for association with reproductive traits. Scrotal circumference and testosterone concentrations were collected monthly from 10 until 16 months of age. Additionally, testicular growth rates were calculated. DNA was amplified by PCR and digested using Msp I and Hae III restriction enzymes. Every polymorphism presented two alleles. The predominant alleles were D (0.85) and F (0.98), respectively, and genotype EE - bGH/Hae III was missing. Significant association (P<0.05) between bGH/Msp I polym

Abstract:

The records of sixty-six yearling and 2-yr-old beef bulls selected for breeding in 1980 and 1981 were used to study the relationships between body weight (BW) and gain measurements, scrotal circumference (SC) and semen characteristics in young beef bulls. The bulls belonged to four breed groups; Hereford, Beef Synthetic, Dairy Synthetic and Pee Wee. A week before the start of breeding season, the bulls were weighed and measured for scrotal circumference. A single prebreeding semen sample was collected by electro-ejaculator from each bull in 1980, while three samples (pre-, mid- and postbreedin
