Characteristics of rural smallholder communities in northern Vietnam, with particular emphasis on dairy farming
The objective of this field questionnaire survey was to provide information about the characteristics of rural smallholder farming communities, which have been targeted by the Vietnamese government's dairy development policy. The results from this study suggest that the adoption of dairy farming is partly determined by pre-existing wealth of the farming households. It is, therefore, more likely ...

Building reservation economies: Cattle, American Indians and the American West
Removal to reservations involved American Indians in changing economies and federal 'civilisation' programs that were fueled by beef cattle, breeding cattle, working cattle (oxen) and dairy cattle. As 19th century reservations expanded, Native Americans negotiated the bovine economies as consumers, labourers, producers, retailers and marketers. Cattle, working oxen and dairy cows were intended to ...

Recently planted vegetation strips reduce Giardia runoff reaching waterways
Current methods for tracking pathogens across farmland and into surrounding waterways via runoff are limited and typically have been developed using artificially created landscapes. No studies have investigated how Giardia in farm runoff moves across the landscape, despite high prevalence rates in dairy cattle (Bos taurus) worldwide. Here, we report the development of a field-based tracking ...

Dietary forage impacts on dairy slurry nitrogen availability to corn
Precise feeding of protein and mineral supplement can maintain high levels of milk production and reduce nutrient excretion in dairy manure and losses to the environment. No information is available on the impacts of feeding different silages to dairy cattle (Bos taurus) on manure N cycling in soils. Slurry from dairy cattle fed rations containing alfalfa (Medicago sativa L.; ALF), red clover ...

Molecular epidemiology of campylobacter jejuni populations in dairy cattle, wildlife, and the environment in a farmland area
We describe a cross-sectional study of the molecular epidemiology of Campylobacter jejuni in a dairy farmland environment, with the aim of elucidating the dynamics of horizontal transmission of C. jejuni genotypes among sources in the area. A collection of 327 C. jejuni isolates from cattle, wildlife, and environmental sources in a 100-km2 area of farmland in northwest England was characterized ...

Effect of covering composting piles with mature compost on ammonia emission and microbial community structure of composting process
Received for publication February 14, 2008. To control ammonia (NH3) volatilization from the dairy cattle (Bos taurus) manure composting process, a compost pile was covered with mature compost and the gas emissions evaluated using the dynamic chamber system. The peak of NH3 volatilization observed immediately after piling up of the compost was reduced from 196 to 62 mg/m3 by covering the compost ...

Equipment of dairy cattle manure treatment organic fertilizer
Now we can see that many dairy farms, chicken farms and other farms are going to buy organic fertilizer equipment. Why? First of all, because the organic fertilizer production equipment can treat the manure of livestock and poultry into organic fertilizer, which fundamentally solves the pollution caused by the manure of livestock and poultry, so that the environmental problems in the farm can be ...

The new alternative to footbaths for cows: disinfection mats
Introducing One of the most important factors contributing to the health and welfare of cows is the quality of their claw care. The most effective way to improve cow claw health is to use a disinfection mat. In this article, we will discuss the benefits of a cow disinfection mat and explain how it works so that you can prevent Mortellaro and hoof inflammation in your dairy cattle. ...

Things You Need To Know About Dairy Cattle Feed Pellets Formulations
Dairy cattle’s stomach is different from pigs, horses, rabbits, and other livestock, generally, feed without sufficient chewing will reach the stomach. It is not only large in volume but also different in structure and function from that of single stomach livestock. Animal feed machine is indispensable equipment to make dairy cattle feed pellets. Zhengzhou Fusmar is a professional feed ...

Statistical modelling of the impact of some polyphenols on the efficiency of anaerobic digestion and the co-digestion of the wine distillery wastewater with dairy cattle manure and cheese whey
The objective of this study was to determine the effectiveness of anaerobic digestion in the treatment of polyphenols (PP) present in olive mill wastewater (OMW) and wine distillery wastewater (WDW). Anaerobic Toxicity Assay (ATA) was conducted to assess the impact of the most representative phenolic compounds present in OMW and WDW: catechol, tannins and p-Coumaric acid, on biogas production. ...

Soil properties and crop yields in response to mixed paper mill sludges, dairy cattle manure, and inorganic fertilizer application
The contribution of organic wastes to crop yields and soil fertility may be influenced by their composition and the soil type. This 6-yr study (2001–2006) evaluated the effects of repeated additions of mineral fertilizers (MF), mixed paper mill sludges (PMS) (18, 36, and 54 Mg ha–1), dairy cattle manure (DCM) (36 Mg ha–1) alone or with reduced mineral fertilizer (60% NPK) (RMF) and a control, on ...

Dairy cattle manure improves soil productivity in low residue rotation systems
Mineral fertilizer alone may not sustain soil productivity in cropping systems that return little crop residues to the soil, unless additional organic residues and/or manure is applied regularly to the soil. The objective of the present study was to assess the long-term effects of mineral fertilization (No fertilizer, PK, and NPK) and manure addition (0 and 20 Mg ha–1 yr–1) on soil physical and ...

Soil seed bank composition in pastures of diverse mixtures of temperate forages
Seed banks may contribute useful or weedy species that fill gaps in pastures. In a previous study, pastures planted to complex mixtures of forages had a lesser proportion of weedy species in the aboveground vegetation. In this study, we relate changes in the species composition of the seed bank to changes in the aboveground vegetation. In August 2001, four mixtures [two, three, six, and nine ...

Seasonal Changes in Airborne Fungi and Bacteria at a Dairy Cattle Concentrated Animal Feeding Operation in the Southwest United States
The objective of this study was to evaluate a dairy located in the arid southwest United States to determine the concentrations and seasonal variation of airborne fungi and bacteria and to determine the percentage of antibiotic resistant Staphylococcus aureus. The authors used two-stage ambient air sampling systems to measure the culturable airborne fungal organisms and bacteria on a monthly ...

Magox for Dairy Feeds and Buffers
Magnesium (Mg) is an essential mineral for dairy cattle. Many forages are deficient and excessive amounts of other minerals, especially potassium (K), can interfere with Mg utilization, resulting in a greater Mg deficiency. While grains and oilseeds contain more Mg than most forages, the total ration still can be deficient. Most dairy nutritionists recommend 0.35% Mg in the total ration. ...

All-Natural KMI Zeolite for Animal Feed, Dairy & Compost
Feed Additive Zeolite is used widely by livestock farmers as an animal feed additive for beef cattle, dairy Cows, Swine, poultry (broilers & egg production), and sheep. Since Zeolite is the World’s only naturally occurring, negatively charged, mineral a great number of benefits in the feed process can result from the basic chemistry of the zeolite as an animal feed additive. Many ...

Research highlights cattle emissions reduction opportunity
Researchers in Denmark have measured the quantities of greenhouse gases in the breath of dairy cows and demonstrated a heritable variability between individual animals. “This means that we have an opportunity to select for breeding those individuals which will produce offspring that generate less methane,” says Dr Jan Lassen who led the research project on individual methane ...
