Feedyard Assessment: Assessor's Guide
Feedyard Assessment: Assessor's Guide
Nebraska Beef Quality Assurance Program
The BQA Feedyard Assessment is an on-site educational tool that allows for assessing and benchmarking key indicators of animal care and well-being as well as feedyard conditions. The Feedyard Assessment focuses on three main areas – Animals, Records and Best Management Practices (BMP), and Facilities and Equipment.

Stocker And Backgrounding Self Assessment
Nebraska Beef Quality Assurance Program
Cattlemen in stocker operations have long recognized the need to properly care for livestock. Sound animal husbandry practices, based on decades of practical experience and research, are known to impact the well-being of stocker cattle, individual animal health and herd productivity. Stocker cattle operations are located in many diverse environments and geographic locations in the United States. A universal set of production practices can not be recommended for all stocker cattle producers in light of the divergent climate and geographic variations of the stocker and backgrounding segment. Personal experience, training and professional judgment can serve as a valuable resource for …

Group Feeding For The Lactating Cow, Anthony Joseph Martin
Dairy Science
Feeding individualized rations for lactating dairy cattle in the commercial herd based on dietary needs is a popular issue. This has been a debating topic since evolution of the Total Mixed Ration (TMR). Since dairymen were able to mix grain in a feed wagon and mix a specific dietary ration to meet the demand for an organized group, there has been an issue in which protocol cow pen grouping should take. Dairymen have always feed cattle based on if lactating or late in their gestation, nonlactating. With the evolution of the TMR dairymen are then allowed to go into more …

Pyrilamine is an antihistamine used in human and veterinary medicine. As antihistamines produce central nervous system effects in horses, pyrilamine has the potential to affect the performance of racehorses. In the present study, O-desmethylpyrilamine (O-DMP) was observed to be the predominant equine urinary metabolite of pyrilamine. After intravenous (i.v.) administration of pyrilamine (300 mg/horse), serum pyrilamine concentrations declined from about 280 ng/mL at 5 min postdose to about 2.5 ng/mL at 8 h postdose. After oral administration of pyrilamine (300 mg/horse), serum concentrations peaked at about 33 ng/mL at 30 min, falling to <2 ng/mL at 8 h postdose. Pyrilamine was not detected in serum samples at 24 h postdosing by either route. After i.v. injection of pyrilamine (300 mg/horse) O-DMP was recovered at a level of about 20 ̄g/mL at 2 h postdose thereafter declining to about 2 ng/mL at 168 h postdose. After oral administration, the O-DMP recovery peaked at about 12 ̄g/mL at 8 h postdose and declined to <2 ng/mL at 168 h postdose. These results show that pyrilamine is poorly bioavailable orally (18%), and can be detected by sensitive enzyme-linked immunosorbent assay tests in urine for up to 1 week after a single administration. Care should be taken as the data suggest that the withdrawal time for pyrilamine after repeated oral administrations is likely to be at least 1 week or longer.
