Bovine Milk Triacylglycerol Regioisomer Ratio Shows Remarkable Inter-Breed and Inter-Cow Variation

Seasonal Variation of Triacylglycerol Profile of Bovine Milk

Milk contains 3-6% of fat, of which the dominant component is triacylglycerol (TAG). Over 100 TAG groups can be readily detected in any non-enriched milk sample by LC-MS; most TAG groups contain several isomers (TAG molecules with different fatty acid composition), which cannot be fully resolved chromatographically by any single stationary phase. TAG profile of mature milk from 19 cows was surv...

Genetic variation within the Lidia bovine breed.

The results of an exhaustive data collection from a bovine population with a low level of exchangeability, the Lidia breed, are presented. A total of 1683 individuals from 79 herds were sampled and genetic diversity within and among lineages was assessed using 24 microsatellite loci on 22 different chromosomes. Expected heterozygosity ranged between 0.46 and 0.68 per lineage and there was signi...

Inter-varietal structural variation in grapevine genomes.

Grapevine (Vitis vinifera L.) is one of the world's most important crop plants, which is of large economic value for fruit and wine production. There is much interest in identifying genomic variations and their functional effects on inter-varietal, phenotypic differences. Using an approach developed for the analysis of human and mammalian genomes, which combines high-throughput sequencing, arra...

Inter-provincial variation in government drug formularies.

In Canada, coverage for ambulatory prescription drug expenditures is provided to some groups by provincial drug plans through a provincial formulary. Little is known about the drugs provincial formularies give access to. We report the variation in availability of new drug molecules (NDM) across provincial formularies. We identified 108 NDM approved in Canada between 1991 and 1998. From each dru...
