“…In organic systems, information on the effect of breed on milk yield is sparse, although seemingly lower than in conventional systems: organic systems are based on pasture utilisation with low concentrate supplementation, a diet that could make interbreed differences less evident. In fact, when comparing different type of diets in conventional systems, Oldenbroek (1988) found that differences between Holstein-Friesian and other breeds, although always present, were more evident with diets with higher amounts of concentrate compared with those based on forages. Moreover, the evolution of the milk yield along the productive life of our organic HolsteinFriesian cows was very similar to that observed in their conventional counterparts.…”

“…In organic farming information of the effect of breed on milk composition is sparse. Similarly to milk yield, organic (pasture-based) diets would make the interbreed influence on milk composition less evident compared with those based on large amounts of concentrate (Oldenbroek, 1988).…”

“…On the contrary, differences in the fat content were lower, with the only exception of Holstein × Brown Swiss cows in farm#2 that produced milk with a high fat content compared to pure Holstein-Friesian. It is well assumed that in conventional systems HolsteinFriesian cows produce higher milk volumes but with a lower fat and protein content compared to other breeds such as Brown Swiss, Jersey or Swedish Blond (Oldenbroek, 1988;Heins et al, 2006a;Vance et al, 2009;Prendiville et al, 2011). Crossbred cows may be beneficial under a milk payment scheme that rewards higher components in contrast to systems where the payment is based on milk volume; in those systems care would have to be taken to select breeds, and bulls within breeds that could maintain milk volume (Bluhm, 2009).…”

Organic systems are highly dependent on the environment and require animals well adapted to local conditions. In Spain, organic dairy farmers are not satisfied with the productive performance of their herds and ask for technical advice to obtain suitable animals for organic systems. The milk productive performance (milk yield, nutritional composition, and somatic cell count) of Holstein-Friesian cows in organic farming in North Spain compared with conventional farms has been analysed. When breed diversity was present in the same organic farm, Holstein-Friesian milk performance was compared with other breeds and/or crosses. Holstein-Friesian cows in organic farming produce slightly less milk than grazing conventional cows, but milk was similar in composition and somatic cell count across systems. The limited data from organic farms where breed diversity exists indicate that Holstein-Friesian cows produce numerically more milk than other breeds and crosses but with statistically lower protein content. Considering that in Spain organic milk production is mostly used for liquid milk consumption and that the payment system is based only on milk volume, Holstein-Friesian cows would better fit the farmer interests than other breeds or crosses. However, in addition to productive performance, reproductive efficiency, animal health and consumer's preferences should be fully considered when selecting a breed for organic production. If Holstein-Friesian was the selected breed, efforts should be made to identify cows within the breed that are best adapted to organic conditions. New productive, reproductive, nutritional and economic studies would be needed to develop a genetic merit index for organic systems.Additional key words: dairy cattle; milk composition; crosses; suitability; production systems.Correspondence should be addressed to Marta López Alonso: marta.lopez.alonso@usc.esAbbreviations used: DCR (dairy control record); FS (farm system); LG (lactation group); SCC (somatic cell count).

“…For instance, a Holstein cow, on average, is larger and produces larger amounts of milk, while a Jersey cow has better fertility, is more efficient at maintaining its body condition during lactation, and produces milk with a higher content of solids (13,(17)(18)(19)26). The relative importance given to certain traits is greatly influenced by circumstances that change priorities.…”

Differences in the Rumen Methanogen Populations of Lactating Jersey and Holstein Dairy Cows under the Same Diet Regimen

In the dairy cattle industry, Holstein and Jersey are the breeds most commonly used for production. They differ in performance by various traits, such as body size, milk production, and milk composition. With increased concerns about the impact of agriculture on climate change, potential differences in other traits, such as methane emission, also need to be characterized further. Since methane is produced in the rumen by methanogenic archaea, we investigated whether the population structure of methanogen communities would differ between Holsteins and Jerseys. Breed-specific rumen methanogen 16S rRNA gene clone libraries were constructed from pooled PCR products obtained from lactating Holstein and Jersey cows, generating 180 and 185 clones, respectively. The combined 365 sequences were assigned to 55 species-level operational taxonomic units (OTUs). Twenty OTUs, representing 85% of the combined library sequences, were common to both breeds, while 23 OTUs (36 sequences) were found only in the Holstein library and 12 OTUs (18 sequences) were found only in the Jersey library, highlighting increased diversity in the Holstein library. Other differences included the observation that sequences with species-like sequence identity to Methanobrevibacter millerae were represented more highly in the Jersey breed, while Methanosphaera-related sequences and novel uncultured methanogen clones were more frequent in the Holstein library. In contrast, OTU sequences with species-level sequence identity to Methanobrevibacter ruminantium were represented similarly in both libraries. Since the sampled animals were from a single herd consisting of two breeds which were fed the same diet and maintained under the same environmental conditions, the differences we observed may be due to differences in host breed genetics.
