Joint breeding value evaluation for fertility in Finnish and Norwegian blue foxes
Autor: Riitta Kempe, Ismo Strandén
Publikováno v: Journal of Animal Breeding and Genetics. 135:472-484
We developed a multiple-trait animal model for blue fox fertility evaluation and estimated genetic parameters simultaneously for seven traits: first three litter sizes (LS), pregnancy rate (PREG), whelping success (WHELP), grading size (gSI) and fur

Breeding for better eye health in Finnish blue fox (Vulpes lagopus)
Autor: Riitta Kempe, Ismo Strandén
Publikováno v: Journal of Animal Breeding and Genetics. 133:51-58
Summary The frequency of eye infections in the Finnish blue fox population has increased during the past decade. Eye infection may incur economic losses to producers due to reduced selection intensity, but ethical aspects need to be considered as wel

Siniketun (Vulpes lagopus) nahkaominaisuuksien, rehuhyötysuhteen ja koon väliset geneettiset tunnusluvut
Autor: Nita Koskinen, Riitta Kempe, Ismo Strandén
Publikováno v: Suomen Maataloustieteellisen Seuran Tiedote
Siniketun tärkeimmät jalostustavoitteet ovat pentue- ja nahkakoko sekä nahan laatu (värin puhtaus, tummuus ja yleislaatu). Merkittävin nahasta maksettavaan hintaa vaikuttava tekijä on koko. Rehu on puolestaan tuotantosuunnan suurin kustannustek

The genetics of body condition and leg weakness in the blue fox (Alopex lagopus)
Autor: Nita Koskinen, Esa Mäntysaari, Riitta Kempe, Ismo Strandén
Publikováno v: Acta Agriculturae Scandinavica, Section A - Animal Science. 60:141-150
In recent years, the size and fatness of blue foxes have increased because the length of the pelt is an important factor affecting its price. However, extreme fatness poses a risk to the animal's welfare and increased body weight (BW) has been suspec

Body condition scoring method for the blue fox (Alopex lagopus)
Autor: Nita Koskinen, Jussi Peura, Minna Koivula, Riitta Kempe, Ismo Strandén
Publikováno v: Acta Agriculturae Scandinavica, Section A - Animal Science. 59:85-92
Breeding for larger size in the blue fox has been successful. Today, most of the animals are large and fat at pelting time, but obesity is also more common. Extreme fatness is detrimental especially for young vixens, because fattening followed by fas

Siniketun rehuhyötysuhteen perinnölliset tunnusluvut
Autor: Nita Koskinen, Esa Mäntysaari, Riitta Kempe, Ismo Strandén, Teppo Rekilä
Publikováno v: Suomen Maataloustieteellisen Seuran Tiedote
Rehu on turkistuotannon suurin kustannustekijä ja siinä saavutettavat säästöt alentavat merkittävästi turkisten tuotantokustannuksia. Kotieläinten parempi rehuhyötysuhde vähentää myös ympäristöpäästöjä. Sinikettujen rehuhyötysuhde

Effect of linseed cake supplementation on digestibility and faecal and haematological parameters in dogs
Autor: Riitta Kempe, Markku Saastamoinen
Publikováno v: Journal of Animal Physiology and Animal Nutrition. 91:319-325
The experiment was conducted with a 6 x 4 cyclic changeover design. Six adult Alaskan huskies were assigned to diets containing 0%, 2%, 4%, 6% and 8% linseed cake. A linear decrease in the apparent digestibilities of organic matter (OM) (p < 0.020),

Risk aversion affects economic values of blue fox breeding scheme
Autor: Jussi Peura, Riitta Kempe, Ismo Strandén, L. Rydhmer
Publikováno v: Journal of animal breeding and genetics = Zeitschrift fur Tierzuchtung und Zuchtungsbiologie. 133(6)
The profit and production of an average Finnish blue fox farm was simulated using a deterministic bio-economic farm model. Risk was included using Arrow-Prat absolute risk aversion coefficient and profit variance. Risk-rated economic values were calc

Genetic parameters of pelt character, feed efficiency and size traits in Finnish blue fox (Vulpes lagopus)
Autor: Nita Koskinen, Riitta Kempe, Ismo Strandén
Publikováno v: Journal of animal breeding and genetics = Zeitschrift fur Tierzuchtung und Zuchtungsbiologie. 130(6)
Summary Pelt character traits (size, quality, colour clarity, darkness) are important economic traits in blue fox breeding. Better feed efficiency (FE) is another economically important and new breeding goal for fur animals. The purpose of this study
