Mass produced factory bred commercial breeds
are very similar genetically.
In the present study, we used 26 microsatellite markers, recommended by the Food and Agriculture Organization (FAO) of the United Nations and the International Society of Animal Genetics (ISAG), to elucidate the degree and pattern of genetic variability in the six indigenous pig breeds in Shandong, explain their genetic relationship, and assess their integrity and degree of admixture with the Western commercial breeds
, Landrace, Yorkshire and Duroc, mainly used in Shandong.
It is assumed that there is considerable difference in growth response, especially late growth, according to dietary limiting AA levels between KND and commercial breeds
It demonstrated that methods used for assessing rare breed numbers are not always applicable to commercial breeds
Washington's documents never mention the breed by name, but the Hog Island sheep probably have more in common with his flocks than with modern commercial breeds
Could this information shed light on how North American commercial breeds
respond to similar circumstances?
The commercial breeds
are usually New Zealand Whites, Californians or crossbreeds thereof.
In the lineups they feel the sheep for meat and fat cover, which will always be superior in the faster-maturing commercial breeds
Our previous study elucidated the genetic variability of Asian native chicken populations and commercial breeds
and genetic relationships among them using seven egg white protein polymorphisms (Kinoshita et al.
Researchers Collaborate with Applied Biosystems to Validate Specific Genetic Polymorphisms for Identifying Individual Pigs from Commercial Breeds
This study was the first attempt to analyze comparative population structure of important commercial breeds
of chicken in India along with some native stock of birds.
Wild swine eat half the portion of commercial breeds
The sequencing DNA panel for SNP detection consisted of two individuals from each of five commercial breeds
in Korea, such as Berkshire, Duroc, Large White, Landrace, and Korean Native Pig (KNP).
The genetic variability analysis within the porcine CS-3 gene employed genomic DNAs from 189 individuals that represented three Chinese indigenous breeds (Tongcheng, Laiwu and Wuzhishan pigs) and three introduced commercial breeds
(Landrace, Yorkshire and Duroc).
Their background and breeding means that they are used to eating a wide variety of plants, so they find it easier to cope on a nature reserve than some commercial breeds
