  2. 1. Genetic and clinical studies of teat traits in the pig

    Author : Helena Chalkias; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : A major goal of pig breeding is to produce sows with good longevity, which can raise many uniform litters with healthy, fast-growing piglets. The fitness of the sow, including the presence of sufficient number of functional teats, is one key to the success of the initial rearing period of the piglets. READ MORE

  4. 2. Hormones and sex steroid receptors in the female pig : effects of mating, artificial insemination, seminal plasma and genistein

    Author : Mattias Norrby; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Artificial insemination (AI) of sows and gilts is replacing mating in many countries. Another change over the last decades is that soya, rich in phytooestrogens, is routinely used in the diet to pigs. READ MORE

  5. 3. Exploiting genomic information on purebred and crossbred pigs

    Author : André Hidalgo; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The use of genomic information has become increasingly important in a breeding program. In a pig breeding program, where the final goal is an increased crossbred (CB) performance, the use of genomic information needs to be thoroughly evaluated as it may require a different strategy of what is applied in purebred (PB) breeding programs.

  6. 4. Genetic Heteroscedasticity for Domestic Animal Traits

    Author : Majbritt Felleki; Erling Strandberg; Lars Rönnegård; Ole Fredslund Christensen; Högskolan Dalarna; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Quantitative genetics; genetic heteroscedasticity of residuals; genetic heterogeneity of environmental variation; genetic heterogeneity of residual variance; double hierarchical generalized linear models; teat count in pigs; litter size in pigs; milk yield in cows; somatic cell count in cows; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Abstract : Animal traits differ not only in mean, but also in variation around the mean. For instance, one sire’s daughter group may be very homogeneous, while another sire’s daughters are much more heterogeneous in performance. The difference in residual variance can partially be explained by genetic differences. READ MORE

  7. 5. Genetic variation, biochemical contents and wound healing activity of Plantago major

    Author : Muhammad Zubair; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Plantago major L. (greater plantain, common plantain) has been used as a wound healing remedy in different parts of the world for centuries. Different bioactive compounds have been proposed to contribute to the wound healing properties of this plant. READ MORE
