BACKGROUND Rhesus monkey models are valuable to the studies of human biology. Reference values for clinical chemistry and hematology parameters of rhesus monkeys are required for proper data interpretation. METHODS Whole blood was collected from 36 healthy Chinese rhesus monkeys (Macaca mulatta) of either sex, 3 to 5 yr old. Routine chemistry and hematology parameters, and some special coagul...

Genetic parameters were estimated between current UK hill sheep breeding goals and lamb carcass composition and muscularity traits derived using X-ray computed tomography (CT). To produce these estimates, a total of 648 lambs from two hill farms were CT scanned at weaning (ca 120 days of age), over 3 years, and total weights of carcass muscle (MUSC), fat (CFAT) and bone (BONE) and internal fat ...

(Co)variance components and genetic parameters for test day ewe body weight of Lori-Bakhtiari sheep were estimated using a random regression model (RRM). The data consisted of 22153 individual body weight records, obtained from 1994 ewes (progeny of 205 sires and 1010 dams) between 371 and 3416 days of age, collected from the flock stud of Lori-Bakhtiari Sheep Breeding Station in Shahrekord, Ir...

The influence of copper upon some physiological parameters and reproduction in ewes was studied. Four groups of animals were investigated: 1/ control ewes (untreated); 2) ewes receiving copper as a supplement over the recommended amount of copper in food (10, 25 or 50 mg Cu/ewe/day); 3/ control, superovulated ewes; and 4) ewes treated with 50 mg copper during one month and then superovulated. A...

Societal and scientific challenges foster the implementation of the ecosystem approach to marine ecosystem analysis and management, which is a comprehensive means of integrating the direct and indirect effects of multiple stressors on the different components of ecosystems, from physical to chemical and biological and from viruses to 5 fishes and marine mammals. Ecopath with Ecosim (EwE) is a w...

Data of 3272 lambing records collected on 818 ewes born from 689 dams and sired by 371 rams were used in the evaluation of ewe lifetime productivity (total number born, number weaned and total weight weaned). These records were collected from ewes born from 1969 to 1994 and which gave birth during the period from 1971 to 1999. Year of birth of ewe and ewe two-tooth liveweight affected the ewe p...

Ewe deaths affect the productivity and profitability in sheep farming systems have potential animal welfare market perception implications. Internationally, there is scant data on timing causes of ewe extensive grazing systems. There no published literature incidence risk factors associated with casting (ewe late gestation accidentally immobilised, often dorsal recumbency). This study, undertak...

East Friesian-sired F1 ewe lambs (n = 27) and Lacaune-sired F1 ewe lambs (n = 31) born in 1999 were compared for lamb production, lactation performance, and udder morphology traits in a dairy sheep production environment in 2000. The ewe lambs were the progeny of seven East Friesian and five Lacaune sires. A contemporary group of high percentage East Friesian ewe lambs (> 3/4 East Friesian, n =...

Large offspring syndrome (LOS) may be initiated in ovine embryos after exposure to in vitro conditions. The objective of this study was to compare various parameters of the gravid uterus on day 140 after fertilization: (i) in ewes (n=4) bred naturally, and in ewes (n=18) after transfer of embryos produced in vitro, and (ii) in single, twin and triplet pregnancies after transfer of in vitro prod...
