Intake profile, milk production, and energy balance of early-lactation spring-calving Holstein Friesian and Jersey × Holstein Friesian dairy cows in high-utilization pasture-based systems
Autor: S. Walsh, L. Delaby, M. Kennedy, N. Galvin, Z.C. McKay, M. Egan
Publikováno v: Journal of Dairy Science, Vol 107, Iss 10, Pp 8058-8071 (2024)
ABSTRACT: Early lactation is a critical period for dairy cows, as energy requirements rapidly increase with the onset of lactation; however, early-lactation DMI in pasture-based systems are under measured. The objectives of this study were (1) to mea

Publikováno v: Journal of Dairy Science, Vol 107, Iss 1, Pp 370-384 (2024)
ABSTRACT: Enteric methane (CH4) emissions of 3 genetic groups (GG) of dairy cows were recorded across the grazing season (early March to late October). The 3 GG were (1) high economic breeding index (EBI) Holstein-Friesian (HF) representative of the

Publikováno v: Frontiers in Veterinary Science, Vol 9 (2022)
Avian pox is a common avian virus that in its cutaneous form can cause characteristic lesions on a bird's dermal surfaces. Detection of avian pox in free-ranging birds historically relied on observations of visual lesions and/or histopathology, both

Predicting grass dry matter intake, milk yield and milk fat and protein yield of spring calving grazing dairy cows during the grazing season
Autor: B.F. O'Neill, E. Lewis, M. O'Donovan, L. Shalloo, N. Galvin, F.J. Mulligan, T.M. Boland, R. Delagarde
Publikováno v: Animal, Vol 7, Iss 8, Pp 1379-1389 (2013)
Predicting the grass dry matter intake (GDMI), milk yield (MY) or milk fat and protein yield (milk solids yield (MSY)) of the grazing dairy herd is difficult. Decisions with regard to grazing management are based on guesstimates of the GDMI of the he

Autor: Ravinder N. M. Sehgal, B. M. Myers, Holly B. Ernest, A. C. Bradshaw, A. N. Galvin, Lisa A. Tell
Publikováno v: The Journal of parasitology. 107(5)
Hummingbirds are vital members of terrestrial ecosystems, and because of their high metabolic requirements, they serve as indicators of ecosystem health. Monitoring the parasitic infections of hummingbirds is thus especially important. Haemosporidian
