Nonstructural carbohydrate concentrations in Timothy as affected by N fertilization, stage of development, and time of cutting
Forages with increased total nonstructural carbohydrate (TNC) concentrations improve the N-use efficiency of dairy cows. This study determined the effect of time of cutting (0700 vs. 1500 h), stage of development (heading and anthesis), and N fertilization (30, 50, 70, 90, and 110 kg N ha–1 as NH4NO3) on the fermentable carbohydrate concentration of timothy (Phleum pratense L.) grown in northern ...

Dairy diet Phosphorus and rainfall timing effects on runoff Phosphorus from land-applied manure
Surface-applied dairy manure can increase P concentrations in runoff, which may contribute to eutrophication of lakes and streams. The amount of dietary P fed to dairy cows (Bos taurus) and the timing of a rain event after manure application may further affect runoff P losses. The objective of this study was to examine dietary P supplementation effects on manure and runoff P concentrations from ...

Dietary cation–anion difference and tetany index of timothy forage fertilized with liquid swine manure
Incidence of metabolic disorders increases when dairy cows (Bos taurus) are fed forages that have a high dietary cation-anion difference (DCAD) (>250 mmolc kg–1 dry matter, DM) or high grass tetany (GT) index (>2.2), both associated with high forage K concentration, often caused by applications of liquid swine manure (LSM). We determined how DCAD and GT index of timothy (Phleum pratense L.), ...

Yield and nutritive value of ‘spring green’ Festulolium and ‘Jesup’ Endophyte-free tall Fescue stockpiled for winter pasture
Pasture-based dairies in the Midwest have a difficult time providing high-quality pasture during winter. Little is known about the yield and nutritive value of festulolium when stockpiled for winter grazing compared to tall fescue. In this study, the yield and nutritive value of ‘Jesup’ endophyte-free tall fescue [Schedonorus phoenix (Scop.) Holub.] and ‘Spring Green’ festulolium [Festulolium ...

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 ...

Agricultural Manure Drying Machine for Cows
Manure drying machines are utilized in agricultural settings to remove moisture from wet manure. The drying process breaks down manure, kills bacteria and creates pathogen-free bedding. The drying process also cuts down on storing and disposing of bulk manure and the costs associated with both activities. Dried Manure Solids (DMS) can be used as bedding for the dairy industry. A lactating ...

Nitrogen losses from dairy manure estimated through nitrogen mass balance and chemical markers
Received for publication February 13, 2009. Ammonia is an important air and water pollutant, but the spatial variation in its concentrations presents technical difficulties in accurate determination of ammonia emissions from animal feeding operations. The objectives of this study were to investigate the relationship between ammonia volatilization and 15N of dairy manure and the feasibility of ...

Three Tips to Reduce Heat Stress in Dairy Cows
Summer is here and with it comes high temperatures, high humidity, and increased chances of heat stress. According to a 2019 Foundation for Food and Agriculture Research study, the US dairy industry experiences $1.5 billion in losses to heat stress annually. With afternoon humidities of 60-70%, and temperatures at 75-77°F, cows may already begin to experience the effects of heat stress ...

Effects of reducing dietary nitrogen on ammonia emissions from manure on the floor of a naturally ventilated free stall dairy barn at low (0–20°C) temperatures
Received for publication December 30, 2008. This study was conducted to determine the potential for reducing ammonia (NH3) emissions from manure deposited on the floor of a naturally ventilated free stall barn by mid-lactation dairy cows fed reduced or normal N diets. Two crude protein (CP) diets (178 g kg–1 [high] and 159 g kg–1 [low] dry matter ), were used. The diets were fed to 48 Holstein ...

Greenhouse gas, animal performance, and bacterial population structure responses to dietary monensin fed to dairy cows
Received for publication January 27, 2009. The present study investigated the effects of a feed additive and rumen microbial modifier, monensin sodium (monensin), on selected variables in lactating dairy cows. Monensin fed cows (MON, 600 mg d–1) were compared with untreated control cows (CON, 0 mg d–1) with respect to the effects of monensin on the production of three greenhouse gases (GHG), ...
