A study was conducted to estimate heritabilities of, and genetic correlations among, body weight (WT) and testicular measurements - scrotal circumference (SC), testicular diameter (TD), testicular length (TL) and epididymal diameter (ED) - in ram lambs between 6, 9 and 12 months old, and relationship of the testicular traits with age at puberty in ewe lambs (AP). Two fat-tailed sheep breeds, th...

BACKGROUND Previous studies have indicated that breakfast has a protective effect against obesity. The aim of this study was to describe the breakfast habits of the Spanish adult population and to assess the possible association between breakfast frequency and the presence of abdominal obesity, in a cross-sectional analysis of the ANIBES Study. METHODS A representative sample of 1655 Spanish ...

We estimated genetic parameters for various phases of body and testicular growth until 550 days of age in Nelore cattle, using Bayesian inference, including correlation values and error estimates. Weight and scrotal records of 54,182 Nelore animals originating from 18 farms participating in the Brazilian Nelore Breeding Program (PMGRN) were included. The following traits were measured: we...

The effects of Trypanosoma brucei infection on testicular morphology and function and the changes associated with treatment of infected dogs with diminazene aceturate were studied using fifteen Nigerian adult male dogs. The dogs were randomly assigned into three groups A, B and C consisting of five dogs each. Groups A and B were infected with 1 × 10(6) trypanosomes and group C was the uninfecte...

The short-term effect of gonadotrophin releasing hormone (GnRH) vaccine was evaluated in ten adult male dogs with mean weight of 8.0±1.2 kg, and age ranging between 1 and 3 years. The first group (control) comprised five intact dogs treated with normal saline, while the second group included five dogs treated with a single subcutaneous injection of 400 μg GnRH vaccine. Semen was obtained from t...

quart bottle, through the rubber stopper of which pass two pieces of glass tubing,?one short,-just reaching the neck of the bottle. To this the can ill a is attached by about four feet of rubber tubing such as is used for infants' feeding bottles. The canuia can be made by the silversmith out of a rupee, or a hydrocele canuia can be firmly tied in. I have on one occasion used a small quill. The...
