One-loop leading logarithms in electroweak radiative corrections, I. Results [PDF]
, 2000 We present results for the complete one-loop electroweak logarithmic corrections for general processes at high energies and fixed angles. Our results are applicable to arbitrary matrix elements that are not mass-suppressed. We give explicit results for 4-

Veterinary Record, EarlyView.Abstract Background During lambing, 10% iodine is often used to protect neonatal navel and ear tag sites. The evidence for its effectiveness is sparse. Recently, a specific navel barrier solution (NBS) was developed. Here, an in vivo field trial compared the two treatments. Methods Ten farms reported data from 6840 lambs. The navel and ear tag sites of

Influence of body weight on reproductive activity in Sarda female lambs
Italian Journal of Animal Science, 2010 One way to improve reproductive performance of ewes is through extending its lifetime productivity. Breeding ewe lambs is one method of improving the reproductive performance in the sheep.

Effects of extended grazing during mid, late or throughout pregnancy, and winter shearing of housed ewes, on ewe and lamb performance [PDF]
, 2007 peer-reviewedA flock of March-lambing ewes was used to evaluate the effects of (i) extended (deferred, winter) grazing of pasture during mid, late or throughout pregnancy, and (ii) winter shearing of ewes housed during mid and late pregnancy, on lamb ...

Veterinary Record, EarlyView.Abstract Background Laparoscopic intrauterine artificial insemination (Lap‐AI) is used in sheep genetic improvement programmes. However, the lambing rate (LR) (i.e., the proportion of inseminated ewes that lamb) following Lap‐AI is variable. Previously, one small UK study investigated factors associated with LR, but it did not adjust for dependencies ...

Implications for early rearing techniques: ovarian dynamic and hormonal effects in Barki Ewes
Journal of Basic and Applied ZoologyBackground Compared to mature ewes, the ovarian dynamics and hormonal characteristics of ewe lambs aged 10–12 months are still poorly understood, although reproductive efficiency in sheep is essential for increasing flock productivity.

Management Strategies for Lamb Production on Pasture-Based Systems in Subtropical Regions: A Review
Frontiers in Veterinary Science, 2020 Sheep production on pasture plays an important role in subtropical climates around the world, with great economic and environmental relevance to those regions. However, this production is much lower than its true potential in subtropical regions, largely

Veterinary Record, EarlyView.Abstract Background Reliable body condition scoring in rabbits is essential in managing healthy bodyweight. The commonly used Rabbit size‐o‐meter (RSOM) has shown poor inter‐rater reliability, particularly among inexperienced raters. This study aimed to develop a reliable, reproducible body condition scoring scale for companion rabbits across breeds ...
