[QUOTE="Margonme, post: 1356503, member: 25776"] HD: Regarding natural resistance in Bos indicus vs Bos taurus: Found this in a reference. [i]Parker and colleagues (89) observed a milder anaplasmosis infection in B. indicus cattle than in B. taurus, while other authors did not find any difference (8, 63 , 141). Parasitaemia with A. marginale is modified by the genotype , B. indicus cattle generating a lower inoculation rate than B. taurus (1 , 6). [/i] Also found this, not specific to anaplasmosis but does indicte better adaptation of indicus influenced cattle to tick borne diseases: [i]Considerable variation both between and within breeds has been observed for tick resistance, with well-documented evidence of greater resistance of Bos indicus breeds compared to Bos taurus breeds. Tick load is affected by several genetically controlled morphological traits, such as coat colour and hair type, as well as genes related to the immune response. Within-breed heritability estimates vary from very low to high.....[/i] [/QUOTE]
