Arteriographic Evaluation of Laminitis Digits in the Hind Limbs of Dairy Cattle

Objective: Laminitis is one of the main causes of lameness in dairy cattle. In this situation the corium blood circulation is disrupted and the production of healthy horny hoof wall is reduced. The purpose of this study was to evaluate the arteriographic pattern of the digital arterial branches in the laminitic digits and to compare them with the normal digits. Design: Original study. Animals...

Atypical Actinobacillosis in a Dairy Cow

Actinobacillosis is an infectious, chronic, generally non-fatal disease caused by Actinobacillus lignieresii. The etiologic agent is a part of the oral flora and causes pyogranulomatous lesions of the soft tissues. A 5-year old, approximately 500 kg cross-breed Holstein cow was presented for the treatment of a large, ulcerated and hemorrhagic mass at the left side of the neck in vicinity of the...

Sire x herd interactions for weaning weight in beef cattle.

Weaning weight records of 44,357 Australian Angus calves produced by 1,020 sires in 90 herds were used to evaluate the importance of sire x herd interactions. Models fitted fixed effects of contemporary group (herd-year-date of weighing subclass), sex, calf age, and dam age and random effects of sire or of sire and sire x herd interaction using REML. Effects of standardizing the data, including...

Ruminant Nutrition: Growing Cattle and Beef Breeding Herd

Data from an experiment utilizing 78 individually fed heifers (407 ± 32 kg) were used to determine relationships of G: F and residual feed intake (RFI) to metabolizable protein balance (MPB), purine derivative excretion to creatinine excretion (PD:C) and 3-methyl histidine excretion to creatinine excretion(3MH:C). Heifers were fed steam-flaked corn based diets containing either 0 (NEG) or 1.5% ...
