Research ArticleOpen accessIn the abstractDetermining the Time Required to Detect Induced Sow Lameness Using an Embedded Microcomputer-Based Force Plate SystemBrady McNeil, Julia Calderón Díaz, Caitlyn Bruns et al.Lameness in swine breeding herds is a common cause of compromised animal well-being and economic loss to pig producers. Current lameness assessment methods are subjective and require intensive training. It has been shown that embedded microcomputer-based force plate systems can detect lameness by measuring weight distributions in livestock. The objective of this study was to determine the minimum time required … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 2 · 25 May 2018 · 7,616 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuality Herbage Production of Dwarf Napiergrass with Italian Ryegrass Cropping under Digested Effluent Application in Southern Kyushu, JapanHadijah Hasyim, Yasuyuki Ishii, Ahmad Wadi, Sachiko IdotaDigested effluent produced by a biogas-plant contains essential plant nutrients to solve the treated and disposal problems of livestock manure. Dwarf variety of late-heading type (dwarf) napiergrass as a perennial summer crop and intercropping of over-sown Italian ryegrass as an annual winter crop were applied to 3 levels of digested effluent in southern Kyushu from 2007 to 2009. Digested effluent … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 1 · 25 Feb 2016 · 7,555 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSustainable Management of Effluents from Small Piggery Farms in MexicoJ.L. de Victorica-Almeida, M. Galván-García, R. Ayala-RuizIn Mexico, pig farming is the third most important livestock activity due to its contribution to the total meat production. However, it is estimated that around 38% of pig farms dispose their wastewaters without any treatment directly into the nation’s water bodies, which in turn has a severe impact in the environment. One reason for not treating is the high … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,369 accessesView PDF Cite
