Six lactating dairy cows in mid lactation were fed either white clover silage or a mixture of white clover and maize silages (70 : 30, dry matter basis). Milk yields (about 20 L/day) and compositions were similar when cows were fed either diet. Altho

Lambs of ewes immunized during pregnancy against somatotropin release inhibiting factor and of corresponding control ewes were separated from their dams at birth before sucking and fed artificially, for 5 weeks, milk harvested mechanically from the e

Responses to immunization against somatotropin release inhibiting factor (SRIF) were compared in lambs injected with SRIF plus either Freund's complete adjuvant (FCA), muramyl dipeptide (MDP), Freund's incomplete adjuvant/muramyl dipeptide (FIA/MDP),

Multiparous ewes, pregnant with twin foetuses, were immunized with a complex of somatotropin release inhibiting factor/bovine serum albumin emulsified in Freund's Complete Adjuvant, or placebo on about days 90, 111 and 132 of pregnancy. At lambing, e

Immunization of cross-bred ewes against somatotropin release inhibiting factor significantly increased (P < 0.01) milk yields, relative to yields of similar non-immunized (control) ewes, without affecting milk composition. Feed intakes of immunized e

Crossbred ewe lambs [Dorset Horn X (Border Leicester X Merino)] fed chopped 1ucerne:rolled barley in the proportions 2:1 at either 36 g kg-1 liveweight (moderate intake) or 40 g kg-1 (high intake) were immunized on four occasions at intervals of 25 d

The experiment comprised two sections. First, radiotracer techniques were used to study the metabolism of IgG1 and IgG2 in 5 non-pregnant and 4 pregnant ewes. In the pregnant ewes, the rates of synthesis for IgG1 and IgG2 were similar to the rates ob

Two separate experiments were conducted to examine the effects of exogenous oestrogen on selectivetransfer of IgG1 into mammary secretion of ewes. In one experiment, non-pregnant ewes were induced to lactate artificially by first developing mammary g

A study was designed to determine whether syntocinon administered to nonpregnant intact and ovariectomized ewes with developed mammary glands would trigger milk secretion in the absence of the milking stimulus. 8 ovariectomized and 4 intact ewes rece

Two separate experiments were conducted with alloxan-induced, diabetic ewes. In one study it was found that the diabetes induced by alloxan could be stabilized with exogenous insulin (1.2-1.3 U h-1). Feed intake and milk yield were maintained at norm
