Introduction The “Grass-fed beef ” label indicates meat that is produced by feeding forages from start to finish without any grain supplementation (USDA-AMS 2007). Many healthful aspects of grass-fed beef have been identified, including lower total fat content and higher content of omega-3 fatty acids, conjugated linoleic acids (CLA), and antioxidants as compared to feedlot-finished beef (Razmi...

due to manual feeding of grass carps in aquaculture, digestion problems in this specie are developing. diagnosing and treating these diseases require a good knowledge of anatomy of digestive tract and its appendixes. the goal of this research is getting acquinted with different parts of grass carps’ digestive tract and their relationship. for this purpose, twenty grass carps were used. first th...

Organic steer production demand several decisions concerning grazing strategy, feeding level in the winter and factors as slaughter weight and length of the fattening period. The production can be difficult to optimise, therefore the objective of this study was to describe a model developed to optimise the fattening and slaughter strategy of steer production concerning economy at an individual ...

The South African grass-feeding leafhopper Vilargus Theron is revised. Vilargus pumilicans (Naudé) is redescribed and the specific status of V. campanus (Naudé) is discussed. Seven new species of Vilargus are described: V. bicornicans sp. n., V. budenticans sp. n., V. dentulicans sp. n., V. lobulicans sp. n., V. simulans sp. n., V. triquetricans sp. n. and V. trunculicans sp. n. A key is provid...

A population of hedgehogs (Erinaceus europaeus L.) in pasture land in Canterbury was fcund to vary between less than four and eight per hectare. Feeding habits were studied through stomach contents and analysis of faeces. Grass grub beetles (Costelytra ualandica) and porina moths (Wiseana cervinta), both important pasture pests, were relatively important food items. Estimates of the number of g...

BACKGROUND Breast-feeding may affect the risk of developing allergy during childhood and may also cause exposure to immunotoxicants, such as polychlorinated biphenyls (PCBs), which are of concern as marine pollutants in the Faroe Islands and the Arctic region. OBJECTIVES The objective was to assess whether sensitization and development of allergic disease is associated with duration of breast...

Growing consumer interest in grass-fed beef products has raised a number of questions with regard to the perceived differences in nutritional quality between grass-fed and grain-fed cattle. Research spanning three decades suggests that grass-based diets can significantly improve the fatty acid (FA) composition and antioxidant content of beef, albeit with variable impacts on overall palatability...
