PERFORMANCE OF CROSSBREED FATTENED CALVES IN COMMERCIAL FARMS IN SPAIN

In the present study, parameters related to animal performance and carcass quality were evaluated in order to technically characterize crossbreed calves under commercial farm conditions. Sixty-six male calves of Holstein Frisian crossed with Rubia Gallega (n=43; 65.15%), Limousine (n= 16; 24.24%) and Belgian Blue-White (n=7; 10.61%) were used, in a ratio representative for the beef industry of the area. Nutriti...

Effects of Two Levels of Quantitative Feed Restriction for a 7-or 14-Days Perio...

Background: Compensatory growth after a feed restriction (FR) period, associated with increased feed intake and digestive adaptation allows the broilers chickens to demonstrate better food conversion efficiency and meat yield when submitted to an early-age food restriction. Differences in levels of feed restriction or on the period of feed restriction need to be adapted to each broilers strain, and should balan...

Priapism associated with lumbar stenosis in a dog

Priapism, a persistent long-lasting involuntary erection of the penis, is uncommon in dogs. In this report, the case of a 13-year-old male Pointer, referred to our services due to persistent exposition of the penis, is described. This condition was consecutive to an intermittent priapism situation lasting for several days, which has been initially attributed to the inflammation and haematoma associated with a p...

Relationship between ultrasound measurements of body fat reserves and body cond...

Several methods have been developed to monitor body fat reserves of farm animals and body condition scoring (BCS) is generally assumed to be the most practical. Objective methods, such as real time ultrasonography (RTU), are accepted methods for measuring fat reserves in several farm species but there is no published information about the use of RTU to monitor body fat reserves in donkeys. The aim of the presen...

Collection of field reproductive data from carcasses of the female Eurasian lyn...

Information about reproductive physiology in the Eurasian lynx (Lynx lynx) would generate knowledge that could be useful in the management of the Swedish lynx population based on the knowledge about their reproductive potential and population development. Age-related differences in ovulation and implantation rates would affect the reproductive output and the development of the population. The aims of this study...

Basic Guidelines for the Collection and Submission of Necropsy Samples

The necropsy (postmortem examination) has a critical importance in the determination of the cause of disease and/or death. However, the necropsy is frequently not the end of the question and after this procedure, it is necessary to perform additional techniques (such as histological and microbiological analysis) in order to achieve a final diagnosis. An interdisciplinary collaboration between pathologists, clin...

Localization of tumor necrosis factor in the canine testis, epididymis and sper...

Tumor necrosis factor (TNF), formerly known as Tumor necrosis factor alpha is now regarded as a natural component of the mammalian seminal plasma (SP). Although not completely clarified, its functions in the SP have been associated with paradoxal roles, such as sperm survival in the female genital tract, while at high levels negatively affect sperm survival and fertility potential. Recently, it has been discove...

Uterine prolapse with associated rupture in a Podengo bitch

A case of uterine prolapse coexisting with uterine horn rupture in a 3-year-old Portuguese Podengo bitch, which is an uncommon occurrence, is described. The female was presented with a history of recent parturition, with delivery of four healthy puppies that were normally tended and nursed. The situation developed after an uneventfully pregnancy, and no direct causative factor was identified. The duration of th...

ospadias in a male (78,XY; SRY-positive) dog and sex reversal female (78,XX; SR...

Hypospadias is rarely reported in dogs. In this study we present 2 novel cases of this disorder of sexual development and, in addition, a case of hereditary sex reversal in a female with an enlarged clitoris. The first case was a male Moscow watchdog with a normal karyotype (78,XY) and the presence of the SRY gene. In this dog, perineal hypospadias, bilateral inguinal cryptorchidism and testes were observed. Th...
