Data collected monthly over a period of two years were live weight, packed cell volume (PCV), nematode faecal egg counts (FECs) and coccidial oocyst counts from faecal analyses for 100 mixed age (3-7 years) indigenous Tswana does. The aims of this experiment were to determine seasonal FECs and coccidial oocysts in these goats and quantify the relationships of these burdens to liveweight and PCV...

licensed dairy farms in the central region of fars province were randomly selected in order to participate in aseasonal prevalence study. a cross-sectional study was designed to determine prevalence at cow and quarterlevel based on clinical signs for clinical mastitis and indirect tests for subclinical mastitis. 6180 quarters from1545 dairy cows were tested by clinical examination and californi...

Northern Arabian Sea is one of the most biologically rich region in the North Indian ocean during winter season. In the present study I wish to investigate the the dynamics behind the enrichment of Chlorophyll-a at the above region using multi satellite observations. Ocean Color Monitor (OCM) imageries are used to identify these areas along the west coast of India during February 2000 & 2001 an...

We examined combination therapy with both lactoferrin (Lf) and antibiotics on clinical mastitis due to Staphylococcus aureus (S.aureus) on drying cows. The clinical symptoms of mastitic quarters were cured 81% of combination therapeutic quarters at 7 days post injection (dpi). Moreover, most of mammary gland secretions (MGSs) in combination therapeutic quarters were normal at 7 days after partu...

Mercury was refluxed in countercurrent molecular stills in order to concentrate 204Hg. Two glass sti lls , with heater and cooler placed outside the distillation columns, and one still, consisting of a glass column heated externally and a stainless-steel cooler placed concentrically inside the column, were used . As compared with a lO-cell steel column described previously, these columns showed...

Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...

The genetic basis, mode of inheritance and recent evolutionary changes of migratory directions in birds are discussed on the basis of published and new experimental evidence. Displacement experiments with wild-caught migrants and orientation tests with hand-reared passerines illustrate that inexperienced young birds possess genetic information about the direction and approximate distance of mig...

The optimization of nitrogen application for root crops such as radish is important not only for yield and product quality (sponginess and hollowness) but also for the environment. Therefore, we evaluated the effect of four levels of N application (0, 150, 300 and 450 mg l-1 N) on three radish cultivars (Saxa, Red Fuoko and White Ghiaccio) grown in pots in autumn/winter (from mid-October to mid...
