Cow age, resilience and productivity of cow–calf systems

Animal Production Science
Context The energy availability for cow–calf systems is related to climate disturbances, and energy use is influenced by the age of the cows. Both factors determine the productivity and resilience of herds after climate disruption. Aims

Excavations of Iron-Age dwellings on the Calf of Eday in Orkney

Proceedings of the Society of Antiquaries of Scotland, 1939
Further excavations of a group of Iron Age dwellings. The largest is a substantial stone-built circular structure identified as a 'potter's workshop' due to the large quantity of associated pottery and peat fires within. Three less substantial circular structures are located close by. The fourth stone-built structure is rectangular and thought to be of

Estimation of the developmental age of the bovine fetus and newborn calf.

The Veterinary record, 1990
Jersey cows from several herds provided 97 fetuses and 24 calves at fixed gestational intervals between 80 and 290 days after conception. The fetuses and calves were killed, weighed and measured and, after dissection, the sizes and weights of a range of skeletal and soft tissues were recorded. Six morphological measurements emerged as most suitable for

The aging Achilles tendon: model-predicted changes in calf muscle neuromechanics

Journal of Biomechanics
Forward propulsion depends on the forces generated by the triceps surae muscles and transmitted through the muscles’ subtendons, which merge and twist to form the Achilles tendon (AT). As people age, the AT may undergo structural changes that could alter the subtendons’ ability to transmit forces or function with some independence ...

[Changes in calf digestion depending upon age and type of feed].

Veterinarno-meditsinski nauki, 1983
Calves were surgically supplied with double fistular anastomoses (duodenal and ileal) to study the dynamic of digestive processes. The experiment was carried out in three periods: sucking, transitive (milk and vegetative feed), and fully vegetative.
