The effects of oral drenching with Co or vitamin B12, drenching frequency and Co via rumen bolus on plasma vitamin B12 concentration in weaned lambs (2022)
Journal Article
Hession, D., Kendall, N., Hanrahan, J., & Keady, T. (2022). The effects of oral drenching with Co or vitamin B12, drenching frequency and Co via rumen bolus on plasma vitamin B12 concentration in weaned lambs. Livestock Science, 266, Article 105108. https://doi.org/10.1016/j.livsci.2022.105108

Weaned lambs (n = 88) were stratified by sex and body weight (BW) and allocated at random to 1 of 10 treatments for 12 weeks (consecutive 6-week periods), to evaluate the effects of supplementation with Co or vitamin B12 (B12) on the concentrations o...

Willow leaves as a cobalt supplement for weaned lambs (2022)
Journal Article
Walker, B., Stoate, C., & Kendall, N. R. (2022). Willow leaves as a cobalt supplement for weaned lambs. Livestock Science, 264, Article 105047. https://doi.org/10.1016/j.livsci.2022.105047

Cobalt is an essential trace element in sheep for the synthesis of vitamin B12 in the rumen to support growth and prevent clinical deficiencies (Pine). Willow (Salix spp.) leaves contain a high concentration of cobalt (∼6 times the requirement of lam... Read More about Willow leaves as a cobalt supplement for weaned lambs.

Working with farmers to optimise mineral balance in grazing sheep (2022)
Journal Article
Clarkson, A., Angell, J., & Kendall, N. (2022). Working with farmers to optimise mineral balance in grazing sheep. In Practice, 44(6), 348-356. https://doi.org/10.1002/inpr.229

Background: Trace mineral analysis is a useful but underused tool in ruminant livestock production. Routine on-farm use of diagnostic techniques can help to ensure animal nutritional requirements are being met through improved supplementation choices...

X-ray absorption spectroscopy of copper and iron in sheep digesta (2022)
Journal Article
Clarkson, A. H., & Kendall, N. R. (2022). X-ray absorption spectroscopy of copper and iron in sheep digesta. Journal of Trace Elements in Medicine and Biology, 72, Article 126987. https://doi.org/10.1016/j.jtemb.2022.126987

Background: The bioavailable supply of copper to ruminants has long been problematic. Complexities in supply exist due to interactions with other dietary elements in the rumen, most notably with iron or molybdenum in combination with sulphur, which c...

Mineral and vitamin supplementation on sheep farms: 
a survey of practices and farmer knowledge (2022)
Journal Article
Hession, D. V., Loughrey, J., Kendall, N. R., Hanrahan, K., & Keady, T. W. J. (2022). Mineral and vitamin supplementation on sheep farms: 
a survey of practices and farmer knowledge. Translational Animal Science, 6(1), Article txac026. https://doi.org/10.1093/tas/txac026

Mineral and vitamin (MV) supplementation is a routine management practice in many pasture-based systems of prime lamb production. The aim of the current study was to establish the MV supplementation practices on Irish sheep farms and farmer's knowled... Read More about Mineral and vitamin supplementation on sheep farms:
