Hanley, Thomas A.; Barnard, Jeffrey C. 2014. Variation in nutritional quality of plants for deer in relation to sunny versus shady environments. Res. Pap. PNWRP-602. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacifi c Northwest Research Station. 30 p. Variation in nutritional quality of natural forages for black-tailed deer (Odocoileus hemionus) was studied in summer and wint...
Forages are a necessary component of diets for lactating dairy cows because they provide coarse fiber needed to optimize rumen function. However, forages alone provide insufficient nutrients to achieve high milk yield, and they must be supplemented with other feed ingredients. Because forage quality is highly variable, their quality must be assessed before diets are formulated. Forages have bee...
The aims of this work were to elucidate the potential of using milk fatty acid (FA) concentration to predict cow diet composition and altitude of bulk milk collected in 10 different European countries and to authenticate cow-feeding systems and altitude of the production area using a data set of 1,248 bulk cow milk samples and associated farm records. The predictions based on FA for cow diet co...
Recently, much of the U.S. has been under drought conditions. Lack of water has limited the availability and quality of normal forages. In addition, livestock producers have often been forced to utilize alternative roughage sources. During normal years, nitrate-nitrogen (NO3-N) is taken up by plants and quickly converted to protein. When forages grow under drought stress, however, they tend to ...
Dry biomass of algae is a good source of nutrients and biologically active substances, which in the last years attracted the interest of the specialists in their search for natural, ecologically and healthy sound foods for the animals. The aim of the present study was to characterize the chemical composition and the nutritive value of the dry biomass of fresh water algae of Chlorella genus cult...
Corn can produce high dry matter yields with one harvest. Corn is a good crop to recycle nutrients from manure and maintain water quality. Corn silage is easily ensiled and generally results in palatable forage with relatively consistent quality and higher energy content than other forages. Corn silage production requires less labor and machinery time than other harvested forages. Thus, the cos...
We conducted a lactation trial with a fresh forage diet in order to evaluate 1) the effects of monensin on nitrogen metabolism, and 2) the Cornell Net Carbohydrate and Protein System (CNCPS). Thirty Holstein cows in midlactation (eight fitted with ruminal fistulas) were gradually introduced to a fresh forage diet. A concentrate mix based on corn meal was fed before the a.m. and p.m. milking tim...
In this experiment eight 1,600 mL dual-flow continuous culture fermenters were used to measure the fermentation pattern of cultivable and pasture forages in camel. Two adult camels were used as rumen inocula donors. Fermenters were fed with 120 g of DM/d in 3 equal portions at 08:00, 16:00, and 24:00 h. The trial contained two treatments of four replicate each in a completely randomized design....
