Partial Tooth-Clipping Of Suckling Pigs: Effects On Neonatal Competition And Facial Injuries, Daniel M. Weary, David Fraser
Partial Tooth-Clipping Of Suckling Pigs: Effects On Neonatal Competition And Facial Injuries, Daniel M. Weary, David Fraser
Farm Animal Husbandry Collection
Piglets are born with fully erupted ‘needle teeth’ which are used in competition for access to teats. Producers often clip these teeth to the gum line soon after birth to avoid any resulting facial lacerations, but this clipping can itself lead to injury or infection. Two experiments investigated the effects on facial injury and piglet performance of the potentially less damaging practice of ‘partial clipping’ whereby only the distal third of the tooth is removed. In Experiment 1, teeth were (1) partially clipped, (2) fully clipped to the gum line, or (3) left intact. All piglets of a litter received …
Stream Channel And Vegetation Responses To Late Spring Cattle Grazing, Warren P. Clary
Stream Channel And Vegetation Responses To Late Spring Cattle Grazing, Warren P. Clary
Ecological Impacts of Animal Agriculture Collection
A 10-year riparian grazing study was conducted on a cold, mountain meadow riparian system in central Idaho in response to cattle grazing-salmonid fisheries conflicts. Six pastures were established along Stanley Creek to study the effects on riparian habitat of no grazing, light grazing (20-25% utilization), and medium grazing (35-50%) during late June. Stream channels narrowed, stream width-depth ratios were reduced, and channel bottom embeddedness decreased under all 3 grazing treatments as the area responded to changes from heavier historic grazing use. Streambank stability increased and streamside willow communities (Salix spp. L.) increased in both height and cover under all 3 …
