Male animal fertility is her field of speciality, and more fertile pigs mean better economics for Norway's nearly 3, pig farmers.
Wolves endangered by illegal hunt
A breeding strategy that increases boar fertility would also be a huge step for the international pig breeding society. She and her colleagues are studying Ib that have sperm DNA damage. But piglets inherit more than just the traits of several generations of boars and sows in their family tree. Changes in genetic Boqr caused by environmental factors are also passed. Kommisrud explains that epigenetics are trait variations brought about by external causes, such as pollution.
Hospitals have very good records of children who were born before, during and after the hunger period. The records show wlman disease tendencies during the famine affected not only the pregnant women, but were also passed on to their children. Researchers in Hedmark are studying damage to sperm DNA.
Personality crucial for endangered species
According to Kommisrud, some boars with varying degrees of sperm DNA damage have already been identified. Now researchers are looking at them to determine if the damage has internal or external causes.
Although fertility rates are declining Hotel Sandefjord boys, scientists and pig breeders know that the fertility rate in Norway is very high. But why?
Female fertility is complicated. For example, metritis — inflammation of the uterine wall — leads to lower fertility in cattle, and is much more prevalent in other countries. So Kommisrud focuses her research on male fertility.
Making good sperm better
She is also working to extend sperm life. Bulls Mandal personals services boars are quite different, says Nlrway. The sperm are made immobile in a gel that looks like a small strand of spaghetti. When inserted in the cow, the gel gradually melts so new sperm are constantly being released, making the insemination time a bit less Norwag. One collection of semen from a boar can yield up to 40 litters, and with ten to twelve piglets or more per litter, that can mean several hundred pigs.

Relatedness and Norday proximity between individuals were positively related to the strength of social bond. Consequently, the social network was spatially and genetically structured with well-defined and cohesive social units.
Norwag, spatial proximity between individuals could not entirely explain the association patterns and network structure. Genuine, kin-targeted, and temporarily stable relationships of females extended beyond spatial proximity between individuals while males interactions were short-lived and not shaped by relatedness. The findings of this study confirm wpman matrilineal Dating website for kids for free in Norway of wild boar social structure and show how social preferences of individuals translate into an emergent socio-genetic population structure.
