The major challenges in diagnosing small ruminant lentivirus (SRLV) infection include early detection and genotyping of strains of epidemiological interest. A longitudinal study was carried out in Rasa Aragonesa sheep experimentally infected with viral strains of genotypes A or B from Spanish neurological and arthritic SRLV outbreaks, respectively. Sera were tested with two commercial ELISAs, t...

An experiment was conducted to determine the effects of unsaturated fatty acids supplementation on growth performance and carcass characteristics of finishing lambs. Thirty-two finishing Afshari lambs (initial weigh 58 ± 5 kg and 8 mo age) were used in a completely randomized design with 4 treatments (slaughtered in time series) and 8 lambs/treatment for the final 30 d before slaughter. The sla...

The aim of this study was to estimate the quantity of antibiotics and classes of antibiotics used in the small ruminant industry in the Netherlands in 2011 and 2012. Twelve large veterinary practices, located throughout the Netherlands were selected for this study. All small ruminant farms associated with these practices that had complete records on the quantity of antibiotics prescribed were i...

BACKGROUND: Chlamydia abortus is a zoonotic bacteriumthat commonly causes abortions in ruminants. This microorganismis one of the most important infectious agents causingabortion and major economic losses in sheep and goats worldwide.OBJECTIVES: The objective of this study was investigatingthe status of C. abortus infection among small ruminantflocks of some regions in Iran. METHODS: A total of...

The overly thin sheep or goat is a common presentation for veterinary intervention, either as the client’s chief complaint or a finding during other herd work. Poor body condition is a non-specific sign caused by a wide variety of underlying pathophysiologic processes. Definitive diagnosis and successful treatment or herd interventions will be facilitated by using a step-wise, problem-based app...

Scientific data for carcass traits of terminal-sire sheep breeds can be used to improve the value of market lambs, but information is lacking for modern terminal-sire breeds in the United States. Thus, the effects of terminal-sire breed on 14 fabricated carcass measurements were determined in F1 wether lambs. Columbia, USMARC-Composite (Composite), Suffolk, and Texel rams were mated with mature...

After a previous 84-d performance phase, a study was conducted using 16 West African Dwarf (WAD) ewes. Ewes (Initial BW 17.5 ± 0.19kg) were used in a completely randomized design to study the effects of increasing level of Mexican sunflower leaf meal (MSLM) on nitrogen balance. The experimental animals were assigned to 4 treatment groups A (O%MSLM), B(15%MSLM), C (30%MSLM) and D (45%MSLM) of 4 ...
