Research ArticleOpen accessPhrase 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 · 8,247 accessesView PDFCite
Research ArticleOpen accessPhrase 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 · 7,555 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleInclusion of Molasses or Glucose Syrup in Starter Concentrate for Dairy Calves: Effects on Diarrheic CalvesMarcelo Cezar Soares, Carlos Eduardo Oltramari, Marília Ribeiro de Paula et al.Severity of metabolic acidosis and other clinical signs in diarrheic dairy calves fed a starter concentrate containing molasses or glucose syrup as a replacement for corn were evaluated. Thirty-two calves were blocked according to birth weight and were divided into four treatments according to starter concentrate composition: (1) Control, starter concentrate based on corn; (2) 5% of molasses as a … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 28 Mar 2016 · 7,254 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEvaluation of Different Oral Rehydration Solutions for Diarrheic Dairy CalvesEvangelina Miqueo, Jackeline Thais da Silva, Fernanda Lavínia Moura Silva et al.Regardless of the causative agent, diarrhea results in large loss of water and electrolytes, which leads to reduced performance and mortality. The aim of this study was to evaluate oral rehydration solutions in order to determine the most effective in restoring electrolytes and water while maintaining animal performance. Forty two calves (14 per treatment) were distributed in one of three … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 4 · 26 Nov 2018 · 8,385 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleIncrease in Crude Protein Content of Milk Replacers with Vegetable Protein: Effect on Health and Dairy Calves' PerformanceEvangelina Miqueo, Thais Manzoni Torrezan, Nathalia Britto Rocha et al.The use of milk replacer instead of whole milk may be an economical alternative to calf-rearing systems. However, together with the volume fed, its composition is critical for high performance, especially regarding the origin of the protein. Two milk replacers with different protein content were evaluated to see the effect on the performance of calves. Thirty-three Holstein calves were distributed … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 1 · 6 Feb 2017 · 7,776 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEconomic Feasibility and Growth Performance of Holstein Friesian Calves Fed Whey-Dangke Fortified Green Calf StarterZyahrul Ramadan, Renny Fatmyah Utamy, Hasbi Hasbi et al.This research evaluated the impact of feeding green calf starter fortified with whey-dangke on Holstein Friesian dairy calves' economic feasibility, growth performance, and health parameters. Experimental diets were applied to 18 Holstein Friesian dairy calves using a randomized complete factorial design with two factors: type of calf starter and level fortification of whey-dangke. The results showed that calves fed different … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 9 Jul 2025 · 3,296 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Saccharomyces cerevisiae and Mannan-Oligosaccharides on Daily Weight Gain and Health of Pre-Weaned Holstein Calves in ChilePedro Melendez, Pablo Pinedo, Maria Paz Marin, Angelica AriasThe objective was to compare the effect of S. cerevisiae and mannan-oligosaccharides on Average Daily Gain (ADG), live weight and health of dairy calves in Chile. Calves were weighed at birth and randomly assigned to 3 groups: (i) Yeast (YS): 5 g/calf/day of a live yeast (n = 25); (ii) Mannan (MN): 3 g/calf/day of mannan-oligosaccharides (n = 25); (iii) … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 1 · 1 Feb 2018 · 8,073 accessesView PDFCite
InvestigationOpen accessIn the keywordsImprovement of the Technology for Young-Stock Breeding of Black-and-White Diary Cattle in the Southeast of KazakhstanDinara Asylbekovna Begaliyeva, Aleydar Saldarovich Alentayev, Abdirakhman Moldanazarovich Ombayev, Dastanbek Asylbekovich BaimukanovIt was found that it is possible to give high-quality starter feeds to calves beginning from the 4th day of age and not later than from the 10th-12th day of age. A high-calorie starter contains 16-18% of raw protein or 20% of protein, if calves are weaned when they are four weeks old or younger.
