Stray voltage threshold is better determined under choice test conditions in sheep

Stray voltage threshold is better determined under choice test conditions in sheep.

Stray voltage (usually <10 V) can occur in farms. However, very little information is available related to sheep. In addition, little work has been carried out on the effects of the contextual conditions under which the animals are submitted to stray voltage. The aims of this study were (i) to determine the threshold voltage at which lambs start to express avoidance behaviour and (ii) to test i...

Voltage Equalization of DC Link capacitors in a CHB-Based PET under the Unbalance Voltage Conditions

The unbalance currents injection by power electronic transformers in order to improve the unbalance voltage conditions of the network causes an imbalanced voltage in the DC link capacitors and creates an active powers inequality in the different phases. In this paper, the proposed control structure independently controls the active power of each phase by modifying the power angle between the vo...

Sheep-goat hybrid born under natural conditions.

The paper reports a 5 year old male sheep-goat interspecific hybrid born under natural conditions. The hybrid was castrated at 10 months of age. Karyotype analysis confirmed that the animal was a male and a hybrid with 57 chromosomes, an intermediate number between sheep (2n=54) and goat (2n=60). Morphological characteristics of the animal were compared with those of castrated male Tswana goats...

Stray voltage and milk quality: a review.

If animal contact voltage reaches sufficient levels, animals coming into contact with grounded devices may receive a mild electric shock that can cause a behavioral response. At voltage levels that are just perceptible to the animal, behaviors indicative of perception (eg, flinches) may result with little change in normal routines. At higher exposure levels, avoidance behaviors may result. The ...
