Publikováno v: Canadian Journal of Animal Science. 74:451-456
Investigations of legume species which do and do not cause bloat suggested that a bloat-safe alfalfa (Medicago sativa L.) might be produced by reducing its initial rate of digestion. This study compared a third cycle alfalfa synthetic selected for a

Publikováno v: Canadian Journal of Plant Science. 73:111-122
A modified nylon bag technique, described in detail in this paper, appears to be an effective method of selecting for a lower initial rate of digestion (IRD) in alfalfa. Breeding for reduced IRD in alfalfa resulted in a 15% reduction in 4-h dry matte

A recessive gene for white sepal colour in sweetclover, Melilotus alba L
Autor: B. P. Goplen
Publikováno v: Canadian Journal of Plant Science. 72:1259-1262
A genetic analysis involving P, F1, F2 and F3 in sweetclover (Melilotus alba L.) revealed that the white sepal trait was controlled by a single recessive gene, designated ws. This trait is characterized by chlorophyll-deficient white sepals and sever

AC Nordica alfalfa
Autor: B. P. Goplen, B. D. Gossen
Publikováno v: Canadian Journal of Plant Science. 74:145-147
AC Nordica alfalfa (Medicago sativa L.) was developed by the Agriculture Canada Research Station at Saskatoon, Saskatchewan. It is similar to Beaver alfalfa in having a broad crown and a tap root with many branches. AC Nordica is 1–2 d earlier in m

RELATIONSHIPS BETWEEN RUMINANT BLOAT AND THE CHEMICAL COMPOSITION OF ALFALFA HERBAGE. I. NITROGEN AND PROTEIN FRACTIONS

Daily bloat incidence was recorded in cattle fed alfalfa silage at Kamloops, British Columbia, during the 1973, 1974 and 1975 growing seasons. The overall bloat frequency was 3.32% of animal days. The occurrence of bloat differed significantly (P b w
