With the ever-increasing demand for animal protein and the continual need for the assurance of proper animal welfare, investigations of preventative strategies for diseases is greatly needed. Specifically in the cattle industry, infectious bovine keratoconjunctivitis (IBK), commonly known as pinkeye, causes a large economic loss to the producer. Ho...
European starlings are one of the most abundant and problematic avian invaders in the world. From their native range across Eurasia and North Africa, they have been introduced to every continent except Antarctica. In 160 years, starlings have expanded into different environments throughout the world, making them a powerful model for understanding r...
The finishing trial was conducted to evaluate the ability of earlage to serve as a roughage source compared to corn silage when both sources were balanced on an NDF basis. Steers were fed in a randomized block design with a 2x2 treatment arrangement, with one factor being NDF source (corn silage or earlage) and the other factor being inclusion ("no...
North American populations of Black Vultures Coragyps atratus have increased and expanded their distribution in the southern and eastern USA. In conjunction with these patterns has been a rise in human–vulture conflicts. To improve our understanding of space use patterns and better inform management, we evaluated the movements of Black Vultures (n ...
The study compared pregnancy rates of beef heifers artificially inseminated with multi-sire semen to single-sire semen at ranch 1 and demonstrated pregnancy to multi-sire sexed semen at rand 2. It was hypothesized pregnancy rates resulting from multi-sire semen would be increased compared to single-sire semen. Ranch 1 heifers were inseminated with ...
A study was conducted to determine which winter-hardy small cereal grain was best suited for early spring grazing. Three species were evaluated: winter wheat, cereal rye, and winter triticale, as a double-cropped forage in a continuous soybean rotation. Within this rotation the number of grazing days is limited, but all three species provided high ...
A finishing trial conducted at the Pan-handle Research, Extension, and Education Center (PREEC) near Scottsbluff, NE evaluated the effect of Vivalto®, a B-vitamin complex, on the feeding performance and carcass characteristics of feedlot steers. The design of the study was completely randomized block design with three treatments, control without Vi...
Implementation of minimal supplemental protein strategies during late gestation may have the potential to minimize any negative postweaning progeny performance while decreasing feed costs. A 3-yr study was conducted to evaluate the effects of mid- to late-gestation supplementation strategies on reproduction, cow body weight, and calf performance in...
In a 2-yr study, data were collected on 118 crossbred cow-calf pairs from March and May-calving herds. On approximately 30, 60, 90, 120, and 210 d postpartum, individual cow 24-h bilk yield was estimated through weigh-suckle weigh techniques. Cow body weight (BW) and body condition score (BCS) were collected weekly through breeding. Calf BW was rec...
Raccoon rabies virus (RRV) has been managed using multiple vaccination strategies, including oral rabies vaccination and trap-vaccinate-release (TVR). Identifying a rabies vaccination strategy for an area is a nontrivial task. Vaccination strategies differ in the amount of effort and monetary costs required to achieve a particular level of vaccine ...
