Genetic structure and diversity of 13 Portuguese native and 3 imported cattle breeds were assessed with 39 microsatellites. Allelic richness per locus was high, with an overall average of 8.3 +/- 2.5. The mean observed and expected heterozygosities were 0.673 +/- 0.043 and 0.691 +/- 0.034, respectively. The mean number of alleles per breed ranged between 5.36 +/- 1.27 and 7.87 +/- 2.66. Brava d...

In many grasslands, grazing by large native or introduced ungulates drives ecosystem structure and function. The behavior of these animals is important as it directs the spatial effects of grazing. To the degree that temperature drives spatial components of foraging, understanding how changes in climate alter grazing behavior will provide guidance for the conservation of ecosystem goods and ser...

ABSTRACT: This study describes an outbreak of acute necrotic hepatopathy associated with spontaneous poisoning by Lantana camara L. in dairy cattle. A herd 15 cows and heifers was introduced into a native pasture limited food supply, and, sixteen days later, eight animals had nasal hemorrhage, fever, lethargy, jaundice, dry, dark stools mucus blood. The clinical course varied from two to five d...

Histopathological findings of eosinophilic myositis in the carcass of a slaughtered Korean native cow are presented. Lesions contained massive fibrous septae with vacuolar changes in some lesions, and the hypercontraction and rupturing of muscle bundles, with replacement by eosinophils. Necrosis and severe eosinophil infiltration were observed. Sarcoplasmic fragmentation and atrophy developed. ...

This paper reports on two species of mites of the genus Cosmolaelaps Berlese, 1903 in Iran--C. dorfakiensis sp. nov., and C. pinnatus sp. nov., extracted from soil and leaf litter samples in Guilan Province, Northern Iran. A key to the species of Cosmolaelaps occurring in the Iran is also provided.

BACKGROUND Head injury (HI) is preventable and knowledge of the epidemiology of children's HI is essential for developing preventive strategies. OBJECTIVES The aim of this study was to survey pediatric HI patients admitted to emergency wards at Poursina Hospital in Rasht, Iran, from 2009 to 2010, and to identify the cause of HI in these children. PATIENTS AND METHODS In this retrospective s...

The objective of this study was to estimate variance components and genetic parameters for growth curve parameters in Guilan sheep. Studied traits were parameters of Brody growth model which included A (asymptotic mature weight), B (initial animal weight) and K (maturation rate). The data set and pedigree information used in this study were obtained from the Agricultural Organization of Guilan ...
