Effects of forage quality and type of protein supplement on intake and digestibility in beef steers and performance of postpartum beef cows

Creator:: White, Jenny J.
Abstract:: Two experiments were conducted to evaluate the effects of forage quality and supplemental undegradable intake protein (UIP) level on intake, digestibility, and performance of beef cattle. In Exp. 1, five ruminally cannulated steers (BW = 456 ± 6 kg) were used in a 6 x 5 incomplete Latin square with...

The influence of cow age on grazing distribution and utilization of mountain riparian areas and adjacent uplands

Creator:: Morrison, Julie A.
Abstract:: The objective of this study was to evaluate the influence of cow age on grazing distribution relative to mountain riparian areas. In each of two years, sixty cow-calf pairs were stratified by age into the following treatments: 1) thirty first calf heifers (442 kg, body condition score (BCS)=4.5), and 2)...

Factors influencing diet composition of beef cattle grazing mixed conifer mountain riparian areas

Creator:: Darambazar, Enkhjargal
Abstract:: Two trials were conducted to evaluate changes in the quantity, quality, and moisture of available forage in the pasture, and shrub utilization by cattle during a 30-d late summer grazing period (Trial 1) and the effect of cow age (experience) on grazing distribution and diet composition (Trial 2) in mountain...

Influence of previous cattle and elk grazing on the subsequent diet quality and nutrient intake rate of cattle, deer, and elk grazing late-summer mixed-conifer rangelands

Creator:: Damiran, Daalkhaijav
Abstract:: Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...

The influence of supplemental alfalfa quality on the intake and utilization of low-quality roughages by beef cattle

Creator:: Weder, Christoph E.
Abstract:: Three experiments were conducted to evaluate the influence of quality of supplemental alfalfa quality on beef cattle consuming low-quality meadow grass (MG) roughages. Fifteen steers (250 kg) were assigned randomly to one of three treatments: 1) meadow grass (5.2% CP), no supplement (MNS); 2) meadow grass plus high quality alfalfa...

Nutritional and managerial considerations for wintering beef cattle in the northern Great Basin

Creator:: Brandyberry, Steven D.
Abstract:: A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...

The effects of timber harvest and herbivory on understory vegetation and composition of beef cattle diets on forested rangelands

Creator:: Walburger, Kenric J.
Abstract:: The objectives of the experiment were to: 1) determine the relationship between overstory canopy cover and ungulate herbivory on understory production composition and diversity and 2) determine the effects of timber harvest, ungulate herbivory and season of use on botanical composition and nutritional quality of beef cattle diets. Three randomly...

Management of stockpiled forages and optimal use of supplements by beef cattle while consuming low-quality forages

Creator:: Suverly, Norman A.
Abstract:: Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X...

Quantities of prostaglandins in whole and extended bovine semen and their potential effect on fertility following insemination

Creator:: Jaeger, John Ralph
Abstract:: Our objectives were to determine 1) the concentration of prostaglandin F2α (PGF2α) in whole and extended bovine semen, 2) if concentrations of prostaglandins in extended bovine semen are correlated to fertility, and 3) if PGF2α administered at the time of artificial insemination would improve conception rate. Concentration of PGF2α tended...
