Castrated dogs showed a slightly weak erectile response to cavernous nerve stimulation compared with normal dogs. Intracavernous injection of acetylcholine induced a dose-dependent increase of intracavernous pressure in normal dogs, however, there was almost no penile response in castrated dogs. Histological study showed a significant higher ratio of collagen tissue/smooth muscle in the corpus ...

One hundred eighty-eight male calves were randomly assigned to one of five treatments at about 6 wk of age t o determine the effect of castration at different weights on feedlot performance and carcass characteristics. Calves were castrated at 70, 230. 320 or 410 kg or left intact. All calves received a 36-mg zeranol implant 6 0 d postweaning and were re-implanted every 56 d for the duration of...

Young male albino rats yawn significantly more than females or castrated males when injected with physostigmine (0.10 mg/kg). Treatment with testosterone (100 micrograms daily) during seven days restores cholinomimetically induced yawning in castrated males, and increases yawning in normal and androgenized females. Treatment with estradiol (200 micrograms daily) during one week does not modify ...

Renal angiotensinogen (ang-n) mRNA concentration in the male WKY rat increases significantly during puberty. Furthermore, renal angiotensinogen mRNA level in the adult female WKY rat is considerably lower than in the male. The present study investigates the role of androgen in differential renal ang-n mRNA expression. Northern and slot blot analyses with a-32P labeled ang-n cDNA (pRang 3) demon...

Objective: This study aims to determine the intake, digestibility of nutriens and growth performance Kacang goats that were given complete feed in terms sex differences, castration treatment. Methods: The research took place experimental enclosure faculty Agriculture, Timor University from Marh October 2021. livestock used 15 young goats, which divided into 3 treatment groups. three groups T1 (...

Recent studies suggest beneficial effects of castration before soft tissue trauma and hemorrhagic shock on splenocyte immune functions. Nonetheless, it remains unknown whether this effect of testosterone depletion is limited to splenocytes or is a generalized effect on immune function. The present study was therefore carried out to determine whether androgen depletion before trauma-hemorrhage a...

The relation between men and women suffering pulmonary tuberculosis is 7/3 in favor to males. Sex hormones could be a significant factor for this difference, considering that testosterone impairs macrophage activation and pro-inflammatory cytokines production, while estrogens are proinflammatory mediator's inducer. The aim of this work was to compare the evolution of tuberculosis in male and fe...

The present study aimed to evaluate the effects of immunocastration on animal growth, carcass traits, and meat quality Nellore cattle receiving or not Ionophore supplementation at pasture with concentrate (semi-feedlot). first experiment (Pasture) was carried out during rainy season, while second (supplemented = Semi-feedlot) conducted dry season. In each assessment, 60 males were allocated int...
