An assay procedure comprising plasma oestrogen extraction into ether, separation of phenolic steroids (oestrogens) from non-phenolic matter, separation of oestrogens by chromatography on Sephadex LH20 and their radioimmunoassay (RIA), using oestrogen

In artificially inseminated cows (AI on day 1) peak concentrations of oestradiol-17β in defatted milk occurred at median times of day 0 during the pre-ovulatory period, days −5 to 2, and day 6 during the post-ovulatory period, days 2–15. Median

Two groups of British Friesian heifers with cyclic ovarian function and the potential for further growth were individually fed a restricted diet at two levels over a 12-week period. Eight heifers receiving the higher level of feed (SP group) and five

Three groups of five lactating dairy cows in the mid-luteal phases of oestrous cycles were given an injection (at time 0 h) of the naturally-occurring prostaglandin F2 alpha (PGF2 alpha) or cloprostenol (a synthetic analogue of PGE2 alpha) at doses r

Progesterone concentrations have been measured in defatted milk of British Friesian cows of four herds during the oestrus cycles (other than short cycles) immediately before artificial insemination (AI) at oestrus and immediately after AI (in non-pre

The relative merits of three hormone treatments of dairy cows: (1) intravaginally administered progesterone and oestradiol benzoate; (2) intravaginally administered progesterone and injected cloprostenol; and (3) injected cloprostenol; begun 35–75

Concentrations of oestradiol-17 beta and progesterone in defatted milk have been used to study the post-partum restoration of ovarian function in 52 autumn-calved dairy cattle. In 32 cows the first preovulatory peaks in oestradiol-17 beta concentrati

Pre-ovulatory peaks in oestradiol-17 beta concentrations were observed on days 1 or 2 and post-ovulatory peaks between days 4 and 7, both in jugular venous plasma and defatted milk, day 1 being the day of the onset of oestrus in the goats. Mean value

High-pressure liquid chromatography (HPLC) has been used to separate oestradiol-17β, oestradiol-17α and oestrone. Oestrogens were extracted from defatted cows' milk collected one day before oestrus, using Sepharose coupled to antiserum having high

The incidence of eleven components of behaviour exhibited by 24 British Friesian heifers, housed in three groups of eight, was recorded for 24 days. All observed behaviour involved the participation of two individuals, these being within groups. The
