Differential expression of microRNAs in the prefrontal cortex as indicators of sheep welfare. [PDF]

BMC Vet Res
Background Indicators that are used to assess animal welfare tend to be non-specific and provide limited information on how a situation is experienced by an animal. There is growing evidence that microRNAs could be useful biomarkers of brain function and

Protein requirements of hair sheep raised in warm areas: a multi-study approach

Scientific Reports, 2022
The protein requirements of hair sheep are a key factor in increasing profitability and decreasing the environmental impacts of nitrogen excretion. The objective of this study was to evaluate the protein requirements of hair sheep.

Development and evaluations of equations to predict empty body weight in pre-weaned hair sheep lambs [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
This research aimed to assess the relationships among shrunk body weight (SBW) and empty body weight (EBW) to develop equations to estimate EBW in 121 pre-weaned hair sheep lambs from different genotypes (Pelibuey, n=39; Katahdin, n=27 and crossbred ...

CHANGES IN SODIUM REQUIREMENT OF THE SHEEP ASSOCIATED WITH CHANGES OF DIET [PDF]

Quarterly Journal of Experimental Physiology and Cognate Medical Sciences, 1966
Observations were made on 3 sheep while their rations were changed from dried grass cubes to fresh frozen grass, then to a dry diet of hay and meals and finally back to fresh frozen grass. In spite of the low sodium intake on the fresh grass, the sheep were neither losing nor gaining sodium up to the time the change to hay and meals was made.

Development and evaluation of a model to predict sheep nutrient requirements and feed utilisation

Italian Journal of Animal Science, 2010
A new feeding system for sheep, called MIPAF, was developed by integrating previously published equations with new  ones to predict energy and protein requirements as well as feed utilization of sheep. Special emphasis was given to  dairy sheep,

The requirement of sheep for cobalt or for vitamin B₁₂ [PDF]

British Journal of Nutrition, 1970
1. Sheep confined topens and given a cobalt-deficient ration which supplied about 30μgCo/d required for maintenance of normal growth rate a Co supplement approaching 40 μg administered per os daily; for maintenance of what appeared, under the conditions of the experiments described, to be the maximum vitamin B12 status of a sheep, namely 3 ng vitamin ...
