	abstract = {Propensity of wool to yellow is defined as its yellowness after  incubation for 14 days at 40 C and 100\% relative humidity. It was  determined for mid-side wool samples from Romney, Coopworth and  Perendale ewes shorn in summer and/or winter. All samples had a high propensity to yellow (mean Y-Z after challenge 13.0  SD 3.2). The breed ranking from lowest to highest was Perendale, Romney  and Coopworth (12.4, 13.1, 13.6, respectively; SED 0.2). Wool shorn in  winter was less susceptible to yellowing than wool shorn in summer (11.7 vs  14.4; SED 0.26) and short wool was less susceptible than long wool (12.0 vs  14.1; SED 0.26). There was a highly significant interaction between wool  length and time of shearing. Propensity to yellow of wool sampled at hogget shearing was not a  significant predictor of propensity to yellow of the adult fleece wool. The  measurement was repeatable between some, but not all, successive shearings  of adult ewes. This suggests that the method used may be useful in selecting  adults to reduce yellowness by breeding.},

	abstract = {The influence of season on the composition of milk from  approximately 200 Beta-lactoglobulin (B-LG) AA and 200 B-lactoglobulin  BB phenotype cows was determined for the 1992/93 and 1993/94 seasons.   Marked seasonal fluctuations were observed in all components measured:  protein, casein, whey protein, ash, lactose, alpha-lactalbumin, B-LG, alpha/s-  casein, Beta-casein, k-casein (k-CN), bovine serum albumin, calcium,  magnesium, sodium, potassium, chloride, and phosphate. Significant  differences in composition were observed between the AA and BB  phenotype milks, with the Beta-LG BB phenotype milk containing more total  protein, casein, fat, and total solids, whereas the Beta-LG AA phenotype  milk contained more whey protein, Beta-LG, and had a higher ratio of Beta-  LG to k-CN. Such differences in composition could have a marked effect on  the physicochemical characteristics of these milks. The higher concentration  of casein found in the Betal-lactogloblin BB type milk should make this milk   type more suitable for the manufacture of cheese and casein.   },
