Research ArticleOpen accessEvery word in the titleManagement of Data for Health Performance Measurement in the Industrialized Dairy HerdMogens Agerbo Krogh, Carsten EnevoldsenOne part of dairy herd management is to handle disease occurrence by means of health promotion, disease prevention, timely medical treatments, or eradication of disease. Supporting this part of herd management is an essential task for the cattle veterinarian. The study objective was to identify principles and tools for analysis of herd health data in industrialized dairy herds. The analysis … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 23 Nov 2012 · 8,257 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTrends in Maximum Daily Rainfall in Marginal Desert Environment: Signs of Climate ChangeKhaldoun A. Al-Qudah, Abdullah A. SmadiProblem statement: Change in intense precipitation has been used as an indicator for anticipated climate change. The trend in maximum daily rainfall in 10 rainfall stations distributed in the north and north east of Jordan has been investigated. Based on mean annual rainfall and geographic location, rainfall stations were divided into subhumid, semi-arid and arid stations. Approach: The regression approach … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 14 Sep 2011 · 7,405 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePublic Perception and the Future of the Illinois Dairy IndustryC. Matthew Rendleman, Phillip R. Eberle, William C. Peterson et al.Problem statement: Illinois dairy production is shrinking both absolutely and relative to other states. If historic trends continue growth will come from larger, more technologically and economically efficient dairy operations. Several expansions that could have slowed the decline have been thwarted by community opposition. This paradox, the need for change versus resistance to growth in dairy farming, motivated the study … …Journal of Social Sciences, Vol. 6, Issue 3 · 30 Sep 2010 · 7,423 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Calcium Supplementation on Growth, Nutrient Digestibility and Fecal Lactobacilli in Dairy CalvesC. Yuangklang, C. Wachirapakorn, H.E. Mohamed et al.Problem statement: Based on earlier studies in veal calves and rats, the hypothesis tested was that high calcium intakes by ruminating dairy calves reduce fat digestibility, but do not affect growth performance due to enhanced colonization of the intestine with lactobacilli. Approach: In dairy calves that were fed on a combination of milk replacer, concentrate on grass hay, the effects … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,250 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDairy Heifer Rearing in Hot Arid Zone: An Economic AssessmentM. A. Razzaque, S. A. Mohammed, T. Al-MutawaProblem statement: Economic losses due to high mortality in young calves born in hot arid zone including Kuwait and a high cost of rearing are the main constraints to this region. Therefore, dairy producers have to depend on importation of pregnant heifers for herd replacement. Research data on cost of heifer rearing from their weaning to first lactation were lacking. … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,547 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Rumen-Protected Methionine on Dairy Performance and Amino Acid Metabolism in Lactating CowsW.R. Yang, H. Sun, Q.Y. Wang et al.Problem statement: Free Met as one of the most limiting AA in dairy cows would be mostly degraded in the rumen. This study was to determine the effect of different levels of Rumen-Protected Met (RPMet) on dairy performance and serum amino acid metabolism. Approach: Thirty-six Holstein cows in similar condition were randomly assigned to six experimental treatments with six replicates … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Jan 2010 · 8,269 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance of Pre-Weaned Dairy Calves under Hot Arid Environment: Effects of Immunoglobulins and Age on Diseases and MortalityM. A. Razzaque, T. Al-Mutawa, S. Abbas, M. BedairProblem statement: A high mortality rate (crude mortality 43.6%) of pre-weaned dairy calves resulted in unavailability of replacement heifers in Kuwait. Dairy producers resorted to import pregnant heifers for herd replacement. This study was undertaken to investigate the effects of dam vaccination and age, serum Immunoglobulin (Ig) on disease syndromes and mortality in pre-weaned calves. Approach: Late pregnant Holstein Friesian … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,560 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Developed Version of Conjugate Gradient Method With a New Parameter for Dai-Liao Conjugacy Condition With an Application to Solar PanelAhmad Alhawarat, Ramadan Sabra, Mehiddin Al-Baali et al.Conjugate Gradient (CG) methods are broadly employed in solving bigger-scale unconstrained optimization problems. Two famous methods are the Hestenes–Stiefel (HS) as well as Polak–Ribière–Polyak (PRP) CG methods, which usually work well in practice. However, they cannot satisfy the Global Convergence (GC) property. To retain and enhance the previous practical behavior as well as rectify the latter difficulty, this paper constructs … …Journal of Computer Science, Vol. 21, Issue 7 · 15 Jul 2025 · 3,153 accessesView PDFCite
