As part of an investigation of factors responsible for a previously reported lower efficiency of carcass lean gain in steers offered grass silage diets, 16 Simmental × Friesian steers (515 (s.e. 6·4) kg) were offered perennial ryegrass silage ad li

In an investigation of factors responsible for the lower efficiency of carcass lean gain seen previously in steers offered grass silage diets 18 Simmental × British Friesian steers (361 (s.e. 5-35) kg) were offered one of three diets: a perennial ry

The synthetic androgen 19-nortestosterone (beta-NT) has been used illegally as a growth promoter in cattle production in the European Union. Elimination of beta-NT and its metabolites in plasma, urine and bile was studied in three cattle with cannula

Attempts were made to produce twin calves by implanting in vitro fertilised and matured (IVF) embryos into dairy cows. Twinning rates were consistently at the lower end of the range reported to have been obtained with in vivo derived embryos. The low

The use of the beta-agonist clenbuterol (CBL) as a growth promoter has been outlawed in European meat production. The detection of its illegal use is dependent on CBL residues persisting in animal tissues for longer than the withdrawal times given by

Portal blood flow (PF) is central to the quantitative characterisation of dietary nutrient uptake. Dilution of PAH (p-aminohippurate) is unsuited to rapidly changing flow and visceral studies often use frequent-feeding to encourage “steady-state”

Steen (1992) demonstrated that grass silage diets sustained lower carcass lean gain per MJ digestible energy (DE) intake than diets of low forage: concentrate ratios (F:CR), at equal levels of DE intake. Jugular concentrations of IGF-1, insulin and g

Studies have shown that reducing energy intake by restricting dry matter intake (DMI) at a constant forage: concentrate (F:C) ratio is more effective at increasing carcass lean and reducing carcass fat content than is reducing energy intake by increa

Thirty specimens of lung obtained by Abram's needle biopsy were examined using direct immunofluorescence. In 2 cases of Goodpasture's syndrome, linear deposits of IgG were demonstrated in alveolar walls. Diffuse deposits of IgG were found in the alve
