15 صفحه اولA comparison of hoof lesions and behaviour in pregnant and early lactation heifers at housing.
Lameness, hoof lesion development and behaviour were compared for two groups of 10 heifers: one in early pregnancy (PH), the other in early lactation (LH). Both groups were housed in the summer in cubicles under identical conditions. Behavioural observations commenced immediately after housing, and then at 2, 4 and 6 weeks post-housing. Locomotion scores were assessed weekly, and feet were exam...
متن کاملCharacterising Lactation Curves in Heifers of Different Breeds First Calved in Moderate or Low Condition
Milk yields were measured every 6 weeks from 21220 days after calving in either moderate or low conditioned groups of Angus, Angus x Friesian or Simford first-calf heifers for 3 successive years. Day of peak yield, peak yield and total 220 day yield were calculated by fitting 3 published equations to data on each of the breed x year x calving condition combinations. All equations ranked breed a...

Claw-free graphs and 2-factors that separate independent vertices
In this article, we prove that a line graph with minimum degree δ ≥ 7 has a spanning subgraph in which every component is a clique of order at least three. This implies that if G is a line graph with δ ≥ 7, then for any independent set S there is a 2-factor of G such that each cycle contains at most one vertex of S. This supports the conjecture that δ ≥ 5 is sufficient to imply the existence of...
