The reactive oxygen species (ROS) which are produced during storage of boar semen are causing oxidative stress and leads to poor fertility. Also, tropical and sub-tropical weather condition adversely impacts the physicomorphological quality and fertility of boar sperm. The aim of this study was to examine the effects of feeding linseed oil to boar on its seminal attributes, sperm kinetics, biomarkers of antioxidant, fatty acid profile of seminal plasma (SP) and sperm and in vivo fertility. Six Hampshire crossbreed boars were fed with 90 ml linseed oil (LIN) whereas six Hampshire crossbreed boars were fed 90 ml canola oil (CON) for 16 weeks. Sperm quality was evaluated (60 ejaculates for each group; a total of 120 ejaculates) for motility, livability, abnormal morphology, acrosomal membrane integrity, hypo-osmotic swelling test (HOST) and sperm kinetic parameters by computer assisted semen analysis (CASA) at 0 h and at 72 h of storage at 17°C. Biomarkers of antioxidant (glutathione peroxidase; GPx, catalase; CAT, total antioxidant capacity; TAC) and malondialdehyde (MDA) were measured in SP and serum. Gas chromatography–mass spectrometry (GC–MS) was used for the estimation of fatty acid composition of SP and sperm. Boars fed with linseed oil had higher semen volume (p < .01) and more total sperm numbers (p < .01). Feeding linseed oil to boar enhanced seminal attributes (p < .05) at 0 h as well as at 72 h of storage. Linseed oil feeding (p < .01) improved biomarkers of antioxidants and significantly (p < .01) lowered the lipid peroxidation in serum and SP. Linseed oil feeding (p < .05) increased the proportion of alpha linolenic (ALA), arachidonic and docosahexaenoic (DHA) fatty acids in SP. The ratio of n-6 to n-3 fatty acids in sperm increased significantly (p < .01) in treatment group. Farrowing rate was significantly (p < .05) higher in treatment group. In conclusion, feeding linseed oil to boar improved the in vivo fertility, enhanced antioxidant capacity and increased the DHA content of SP and sperm. 相似文献

There are about 800 different species of wild edible crops in India, out of which about 300 species are used mostly by the tribal and rural population of the North-eastern region alone. This region is the natural reservoir of a number of wild edible fruits. These naturally occurring fruit are not only nutritionally and medicinally rich but also thrive well under adverse climatic conditions and are resistant to biotic and abiotic stresses. In spite of their potential, these fruits are unattended both at scientific and farmers level. Due to lack of proper documentation, the information about the ethno-botanical uses of these fruits have been lost at an alarming rate. Therefore, an attempt has been made during 2015–16 at to enumerate the ethno-medicinal uses and socio-economic importance of wild edible fruits of Mokokchung district of Nagaland, India. In the present study, altogether 55 wild edible fruit species belonging to 29 families have been enumerated. These fruits are used traditionally for the treatment of gastro-intestinal disorders, respiratory ailments, urogenital problems, dermatological problems, fever, cuts and wounds, diabetes, jaundice, cardiovascular problems, nutritional disorders, antidote, bone diseases, cancer, toothache, opthalmia, ENT, food poison, malaria and allergy. In addition, these fruits have also been use in the socio-economic life of the rural people as constructional timber, firewood, fodder, charcoal, fish poisoning, dyes, oil etc. Although, these fruits play an important role in the social and cultural life of rural people, but most of them are going to be extinct due to a number of factors. Therefore, there is urgent need to conserve these species for livelihood security of rural people. 相似文献
