The sources of variation of health claimable omega-3 polyunsaturated fatty acids (eicosapentaenoic acid, EPA+docosahexaenoic acid, DHA) in 2000 Australian lambs were investigated using 98 sires (Merino, maternal or terminal breeds) that were mated to about 5000 Merino or crossbred (Border Leicester×Merino) ewes. Pasture was supplemented with feedlot pellets, grains or hay as necessary, when the...

Cryo-electron tomography (cryo-ET) has emerged as perhaps the only practical technique for revealing nanometer-level three-dimensional structural details of subcellular macromolecular complexes in their native context, inside the cell. As currently practiced, the specimen should be 0.10.2 microns in thickness to achieve optimal resolution. Thus, application of cryo-ET to intact frozen (vitreous...

OBJECTIVE The purpose of this study was to histologically analyze allografts from cadaveric semitendinous muscle after cryopreservation at -80 degrees C in comparison to a control group kept at only -4 degrees C to test the hypothesis that the histological characteristics of the tissue are maintained when the tendons are kept at lower temperatures. METHODS In a tissue bank, 10 semitendinous t...

skeletal abnormalities are most often used to describe defects in the arms or legs that are associated with genes or chromosomes, or that occur due to an event that happens during pregnancy. spider lamb syndrome (sls) is a congenital disorder in sheep breeding that is recognized by some deformities in skeletal system especially in the limbs.a dead day-old cross-breed white lamb with deformed li...

background toxoplasma gondii is an obligate, intracellular parasite, which is widely spread in the world. the parasite is able to infect all warm-blooded hosts including human.the infection occures via consumption of food or water containing oocytes, eatingundercooked meats containing tissue cysts, and placenta. undercooked meat consumption is one of the most important ways of toxoplasma transm...

The impact of selecting for lean meat yield using breeding values for increased eye muscle depth (PEMD) and decreased fat depth (PFAT) on the consumer acceptance of lamb meat was evaluated. Consumer sensory scores (tenderness, juiciness, flavour, odour, overall liking) were obtained for the longissimus lumborum (loin) and semimembranosus (topside) muscles of 1471 lambs. On average loin samples ...

The effect of different periods of display and/or storage, as practiced under retail conditions for frozen turkey upper arms in Nigerian open markets, on physical appearance, odour and extent of lipid peroxidation of the meat was investigated. Five batches of frozen turkey shipments, sampled bi-monthly at 45 upper arms per batch were used. The frozen upper arms from each batch were displayed on...

Severe discharge of sewage and industrial effluents into the Persian Gulf leads to the deposition of various types of heavy metals, especially lead and mercury, in the muscles of fish. Total mercury and methylmercury contents were determined in the edible parts (muscle tissue, fillet) of two different most popular frozen fish species from the Persian Gulf to ascertain whether the concentrations...

A progeny test was conducted in Western Australia in conjunction with the national central progeny test (CPT) program to evaluate 14 American Suffolk and 2 Australian rams as prime lamb sires, 4 of these rams having been evaluated previously in the national CPT program. The American Suffolks produced lambs that were heavier and had leaner carcases than lambs from the Australian sires. However, ...

Chorioamnionitis (inflammation of the fetal membranes) is strongly associated with preterm birth and in utero exposure to inflammation significantly impairs contractile function in the preterm lamb diaphragm. The fetal inflammatory response to intra-amniotic (IA) lipopolysaccharide (LPS) is orchestrated via interleukin 1 (IL-1). We aimed to determine if LPS induced contractile dysfunction in th...
