ANIMALS 1,637 dogs > or = 6 months old of the following breeds: Akita, Bloodhound, Collie, Great Dane, Irish Setter, Irish Wolfhound, Newfoundland, Rottweiler, Saint Bernard, Standard Poodle, and Weimaraner.

A deterministic beef efficiency model (BEM) was used to evaluate life-cycle herd efficiency (LCHE) in cow-calf beef production systems using four breed groups of beef cattle. The breed groups were Beef Synthetic #1 (SY1), Beef Synthetic #2 (SY2), Dairy Synthetic (DS), and purebred Hereford (HE). The LCHE was defined over the lifetime of the herd as the ratio of total output (lean meat equivalen...

OBJECTIVES To investigate the dependence of echocardiographic ratio indices (ERIs) on age, body weight (BW) and breed/study group using individually contributed and published summarized data in dogs. BACKGROUND ERIs allow for narrow prediction intervals of M-mode echocardiographic measurements in generic adult dogs. Breed and age-specific differences have not been examined systematically usin...

BACKGROUND Parasitological investigations on paramphistomosis were carried out over a 12-month period in the southeast of Iran to determine the prevalence and intensity of this disease. METHODS A total of 1000 cattle, Sistani breed (n= 450) and Brahman breed (n= 550) of all sex and age groups were inspected at random for the presence of paramphistomidae flukes in Zabol slaughterhouse from Dec...

eighteen primiparous rabbit does comprising of six per breed of new zealand white (nzw), chinchilla (cc) and dutch belted (db). they were randomly allocated to three rebreeding interval groups of 7, 14 and 21 days postpartum. three breeding males, one per breed were used giving a total of 21 rabbits. significant (p

Water buffaloes (Bubalus bubalis) are quite well adapted to climatic conditions in the Amazon, and in this biome, they are noted for the considerable amount of meat and milk they produce and how hard they are able to work. Because of a lack of research dedicated to improving the rearing of buffaloes in the Amazon, the objective of this study was to genetically characterize the Murrah and Medite...

To clarify the genetic ancestry and the mitochondrial DNA (mtDNA) diversity of the Lidia cattle breed, a 521-bp D-loop fragment was sequenced in 527 animals belonging to 70 herds distributed across 29 lineages. The mtDNA diversity recorded was similar to that seen for Middle Eastern breeds and greater than that recorded for the majority of European breeds. Haplotype T3 was the most common (81%)...

BACKGROUND Previous research has indicated a breed predisposition to gastric carcinoma in dogs. However, results to date are inconsistent since several studies have failed to prove such a predisposition. Better knowledge of breeds at risk could facilitate early detection of gastric carcinoma in dogs. The aim of the study was to retrospectively investigate the proportion and possible breed predi...

The objectives of this study were to evaluate the influence of different pure pig breeds and muscle types on the expression of muscle proteins, as well as their interactions, and second, to find biomarkers for breed and muscle types. A total of 126 male pigs, including 43 Landrace, 21 Duroc, 43 Large White, 13 Pietrain, and 6 Belgian Landrace, were slaughtered at the age of 174 +/- 6 d. Samples...

BACKGROUND The Korean native pig (KNP) is generally thought to have come from northern China to the Korean peninsula approximately 2000 years ago. KNP pigs were at the brink of extinction in the 1980s, since then efforts have been made to restore the breed by bringing together the remaining stocks in South Korea. As a result, KNP was registered as a breed in 2006. To find additional breed-speci...
