Oat (Avena sativa L.) traditionally has been a major crop for feed and forage in Turkey. Theobjective of this research was to study hay yield and quality of oat genotypes harvested at thelate milk stage. One hundred oat varieties of worldwide origin were compared in fieldexperiments in Samsun (northern Turkey) over two growing seasons (2007-2008 and 2008-2009).Significant differences between th...

Reproductive performance was evaluated in beef heifers born over a 2-yr period to determine the effects of target breeding weight (TBW) and development system (SYS) on growth and subsequent reproductive efficiency. Spring-born Angus heifers (253 ± 0.7 kg) were randomly allocated over 2 consecutive yr (yr 1, n = 80; yr 2, n = 96) to be developed to either 55% (350 kg) of mature BW (moderate gain...

AIM To investigate the effect of pre-partum prilled fat feeding on dry matter intake (DMI), energy balance and milk production in Murrah buffaloes. MATERIALS AND METHODS Advance pregnant Murrah buffaloes were either received a dietary supplement of prilled fat at 100 g/day for 35 days pre-partum and at 150 g/day for 95 days post-partum (supplemented group [SG]) or did not receive fat suppleme...

Carotenoids are unstable compounds and are easily degraded to a variety of products in the presence of oxygen and light as well as at elevated temperatures. Ohloff (1972) hypothesised that carotenoids are precursors of aromatic compounds such as C13-norisoprenoids. Recently, several C13-norisoprenoids have been identified upon liberation from their bound forms in grapes and wines (Sefton et at....

Anthropogenic nitrogen (N) emissions can have considerable effects on terrestrial ecosystems, with chronic N deposition leading to changes in plant species composition. The Athabasca Oil Sands Region (AOSR) represents a large point source of emissions, which has prompted concern for surrounding habitats. objective this study was determine the relative importance as driver community composition ...

BACKGROUND The hydrological cycle is an important way of transportation and reallocation of reactive nitrogen (N) in forest ecosystems. However, under a high level of atmospheric N deposition, the N distribution and cycling through water flows in forest ecosystems especially in bamboo ecosystems are not well understood. METHODOLOGY/PRINCIPAL FINDINGS In order to investigate N fluxes through w...

Twelve Dorper × Pelibuey wether lambs (26.8 ± 1.6 kg initial BW, 5 mo of age) were used to evaluate effects of zilpaterol hydrochloride (ZH) on feedlot performance, and effects of ZH and ZH supplementation period (15 and 30 d) on nutrient intake and digestibility. Lambs were blocked by initial BW, and assigned randomly within BW blocks to 1 of 2 treatments: i) control (no ZH), and ii) supplemen...

Abstract Repeat breeder is a problem faced by cattle farmers in Indonesia. The highest reproductive disease commonly occurring repeat conditions reaching up to 32.76%. Limited feed cause cows have low Body Condition Score (BCS) so that the energy utilization process body not optimal and there decrease BCS which causes disturbances performance. If mineral deficiency body, metabolic will be disru...

We evaluate the impacts of different nutrient management strategies on potential for co-managing estrogens and nutrients in environmental waters Potomac watershed Chesapeake Bay. These co-management approaches represent agricultural urban runoff, wastewater treatment plant effluent, combined sewer overflow replacements. Twelve estrogenic compounds their metabolites were analysed by gas chromato...

We analyzed groundwater-transported nitrogen (N) exports from 41 watershed segments that comprised 10 Cape Cod, Massachusetts watersheds to test the hypotheses that chemical form of N exports is related to land use and to length of flow paths through watersheds. In the absence of human habitation, these glacial outwash–plain watersheds exported largely dissolved organic N (DON) but at relativel...
