  • The Curious Divide between Conservation Science and IA

    Since returning to academia, I have been struck by a particular disjuncture between the biodiversity sciences and IA practice in my country, Namibia. Having worked across Africa, my suspicion is that it probably applies to the entire continent, perhaps even broader. Allow me to expand. I had my wildlife scientist hat on a few weeks ago at a southern African symposium on wildlife tracking and ...

  • Valtra and Kesla are a perfect combination for forestry work

    Valtra and Kesla are an ideal pairing for forest tasks. Customers have used Valtra-Kesla combinations for years, of course, but now the two companies are also teaming up in product development and the sales network. For example, in Finland and some other markets Valtra and Kesla products can be purchased from the same dealer. The Unlimited Studio at the Valtra factory in Suolahti has also ...

  • The Ins and Outs of Cattle Nutrition

    They say, “You are what you eat.” What goes in and out of our bodies is obviously important for our general health and maintenance. Well, the same holds true for our cattle as well, but with one main difference: Where we only have one stomach to worry about, they have four! Cattle are animals technically classified as ruminants, a distinction that includes sheep, ...

  • Bull Calves Need Care Too

    By far, most bull calves will never become a lasting benefit to a dairy herd, and as such may not always receive the same level of care that heifer calves do. Harmonizing your calf rearing programs will yield positive results for all calves and your bottom line. All calves require excellent care, especially in the first few days of life. Without adequate, timely colostrum and proper ...

  • Performance of airlift MBR for on-site treatment of slaughterhouse wastewater in urban areas of Vietnam

    In many cities in Vietnam, wastewater generated in slaughterhouses is normally discharged directly into surface waters without treatment. Management of slaughterhouse wastewater (SHWW) is difficult due to the lack of infrastructure for conveyance to centralized facilities. On-site treatment presents one cost-effective way of managing SHWW compared to mass improvement of infrastructure. This ...

  • Revolution through fresh sugar cane juice centers

    This is quite common street business found everywhere in India. Sugarcane juice vendors extract sugarcane juice in presence of customers and serve the glasses of fresh juice to the people. Mostly this business is on the street, very rarely in shops. Small sugarcane crushers are mostly driven by 1 hp motor where repeated crushing is done many times to extract enough juice. Hand ...

  • Analysis and dissipation of the antiparasitic agent ivermectin in cattle dung under different field conditions

    Cattle treated with the veterinary parasiticide ivermectin (IVM) fecally excrete residues. Here we report the exposition and dissipation characteristics of these residues in dung of IVM‐treated cattle, and in soil beneath this dung, on pastures including Canada, France, Switzerland, and The Netherlands. Residues were quantified for dung collected from cattle after 3, 7, 14, and 28 d post‐ ...

  • Degradation and transformation of 17α‐trenbolone in aerobic water‐sediment systems

    Synovex® ONE is an extended‐release implant containing the active ingredients estradiol benzoate (EB) and trenbolone acetate (TBA) for use in beef steers and heifers. TBA is rapidly hydrolyzed in cattle to form 17β‐trenbolone and its isomer, 17α‐trenbolone, which are further transformed to a secondary metabolite, trendione. As part of the environmental assessment for the use of Synovex® ONE, ...

  • Degradation and transformation of 17α‐estradiol in water‐sediment systems under controlled aerobic and anaerobic conditions

    17α‐Estradiol is one of the principal metabolites in cattle excreta following the administration of Synovex® ONE, which contains estradiol benzoate (EB) and trenbolone acetate (TBA). As part of the environmental assessment of the use of Synovex® ONE, data were generated to characterize the fate of 17α‐estradiol in the environment. Studies were conducted to determine the degradation and ...

  • Adsorption isotherm and kinetic studies of As(V) removal from aqueous solution using cattle bone char

    The As(V) adsorption onto bone char was investigated as a function of bone char dosage, pH and contact time in batch tests. The initial As(V) concentrations were varied from 0.1 to 1 mg/L to evaluate the adsorption kinetics and isotherm. The As(V) concentrations were analyzed using a graphite furnace atomic absorption spectrophotometer. The highest As(V) removal was found to be 62% after 3 d ...

  • Validation of a standard field test method in four countries to assess the toxicity of residues in dung of cattle treated with veterinary medical products

    Registration of veterinary medical products (VMPs) includes the provision that field tests may be required to assess potential non‐target effects associated with the excretion of product residues in dung of treated livestock (Phase II, Tier B testing). However, regulatory agencies provide no guidance on the format of these tests. Here, we report development of a standardized field test method ...

  • The potential of ultrasonic membrane anaerobic systems in treating slaughterhouse wastewater

    Direct discharge of slaughterhouse wastewater causes serious environmental pollution due to its high chemical oxygen demand (COD), total suspended solids (TSS) and biochemical oxygen demand. In this study, an ultrasonic-assisted membrane anaerobic system was used as a novel method for treating slaughterhouse wastewater. Six steady states were achieved, using concentrations of 7,800–13,620 mg/l ...

  • Sustaining Mali’s Inner Niger Delta

    The Inner Niger Delta in central Mali is a giant green oasis on the edge of the Sahara desert. It is one of the country’s most productive areas, but also among its poorest. At the height of the wet season, when the River Niger is swollen by heavy rainfall in Guinea, an area the size of Belgium, from Mopti to Tombouctou, turns into a landscape of lakes. As I discovered on a previous ...

  • Have Your Steak and Eat It, Too

    In our recent feature, “Has Meat Met Its Match?,” writer Rowan Jacobsen explores ways people can (now and possibly in the future) reduce the environmental and food security impacts of their diets, including entomophagy (bug-eating), synthetic meat and vegetarian substitutes. If none of those fits your needs, there are plenty of other ways ...
