	abstract = {The properties of the milk serum protein alpha-lactalbumin are  reviewed with special emphasis being placed on its central role in  determining the lactose and water content of milk. Much circumstantial  evidence suggests that artificial depression of alpha-lactalbumin  synthesis should decrease lactose synthesis and that this will, in turn,  decrease the water content of milk. Experimental evidence indicates,  however, that patterns of alpha-lactalbumin gene expression in lactating  ovine and bovine mammary tissue are complex and we should be cautious in  making such predictions. Studies with transgenic mice expressing either  elevated or depressed levels of alpha-lactabumin will be required to  settle this question. In the meantime, a promising line of research is  the investigation of dairy cattle carrying variant alpha-lactabumin  genes. It is possible that correlations will be found between some of  these variants and both the water content and protein yield of milk.  Conceivably, selective breeding of cattle carrying variant proteins may  prove a more practical means of altering alpha-lactalbumin synthesis  than current transgenic techniques.  },

	abstract = {From a population of 1270 Coopworth ewe hoggets 70 were selected   for high greasy fleece weight (CHFW) at hogget shearing and 50 controls   were selected at random (CC).     The CHFW ewes were joined in 1987 and 1988 to sires from a Romney high   fleece weight (RHFW) flock, also mated contemporaneously within that   flock. The CC were mated with commercial Coopworth rams. The CHFW and   CC flocks were grazed with the RHFW flock and its control (RC). Results   for progeny showed that relative to the RC (100) the greasy fleece   weight of the RHFW, CC and RHFW x CHFW were 118, 112 and 125   respectively. Corresponding values for lamb fleece weight were 112, 106   and 121; and for October (12 month) live weight were 106, 109 and 114   respectively. RHFW rams crossed with CHFW ewes generated progeny   markedly superior to Romney and Coopworth controls for greasy fleece   weight, showing that appropriate breeding programmes can rapidly improve   this trait.    },
