Extract

Choice of breed

A model should be developed to allow the selection of the optimal breed on the basis of production traits and economic efficiency.

Choice of selection method

New breeding schemes to replace the current widespread use of progeny testing should be examined critically and, in particular, breeding schemes incorporating multiple ovulation and embryo transplant should be assessed.

Identification of marker traits

Research to evaluate the relevance of marker traits to milk quality should be pursued.

Genetical engineering

Long-term prospects of applying genetical engineering techniques to cattle should be assessed in terms of desk studies.

Nutritional manipulation of milk fat

The biochemical and metabolic aspects of lipid protection in the rumen should be examined further.

Nutritional manipulation of milk protein

Further studies should be undertaken to examine the effects and possible benefits of protein and specific amino acid protection.

New milk products

Work should be conducted to increase the range of marketable products of high added value, particularly new types of cheese for export.

Alleged relationship between milk fat and coronary heart disease (CHD)

The alleged causal relationship between dietary fat and CHD should be examined critically, particularly the definition of safe levels of serum cholestrol in man.
