Research ArticleOpen accessInfluence of Dietary Curcumin on Rumen Fermentation, Macronutrient Digestion and Nitrogen Balance in Beef CattleT. Vorlaphim, M. Phonvisay, J. Khotsakdee et al.Abstract: Problem statement: Previous studies have shown that curcumin has antibacterial activity. It was hypothesized that the feeding of curcumin to ruminants may disturb rumen function and affect macronutrient digestibility and nitrogen utilization. Approach: In an experiment with Latin-square design, beef cattle were fed rations consisting of urea-treated rice straw and concentrates without or with 0.1 or 0.2% added curcumin. … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 26 Jul 2011 · 9,152 accessesView PDF Cite

Research ArticleOpen accessInteractive Effects of the Feeding of Leucaena Leaves and Curcumin on Macronutrient Digestion and Nitrogen Balance in Beef CattleC. Yuangklang, J. Khotsakdee, K. Vasupen et al.Abstract: Problem statement: The feeding of curcumin to beef cattle has been shown to increase nitrogen retention and decrease the apparent digestibility of acid detergent fiber in beef cattle. It was suggested that there could be interactions between the effects of curcumin and the composition of the ration. Approach: In this study with beef cattle, concentrates without or with curcumin … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,067 accessesView PDF Cite

Research ArticleOpen accessEffect of Replacement of Soybean meal by Dried Tomato Pomace on Rumen Fermentation and Nitrogen Metabolism in Beef CattleC. Yuangklang, K. Vasupen, S. Wongsuthavas et al.Problem statement: Dried tomato pomace may be considered as an alternative feedstuff in ruminant nutrition. The limited literature data that are available so far may be interpreted as indirect and suggestive evidence for diminished ruminal fermentation and bacterial synthesis after substitution of dried tomato pomace for soybean meal. Approach: Rumen-fistulated beef steers were used to address the questions whether the … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,867 accessesView PDF Cite

Research ArticleOpen accessEffect 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 PDF Cite

Research ArticleOpen accessNephrocalcinosis in Female Rats Fed Diets Containing Either Pectin, Galacturonic Acid or GlucoseH.E. Mohamed, A. Alhaidary, A.C. BeynenProblem statement: In our earlier study, dietary pectin has been shown to promote nephrocalcinosis in rats when compared with the feeding of cellulose. It was not known whether this pectin effect relates to its structure or to its monosaccharide component, galacturonic acid. Approach: The effects of dietary pectin, galacturonic acid and glucose on kidney calcification were studied in female rats. … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 14,717 accessesView PDF Cite

Research ArticleOpen accessNephrocalcinosis in Female Rats Fed Diets Containing Either Pectin or CelluloseAhmed Alhaidary, H.E. Mohamed, A.C. BeynenProblem statement: There is evidence that the type of fiber influences the development of nephrocalcinosis in rats, but the effect of pectin was unknown. Approach: The effects of dietary pectin and cellulose on kidney calcification were studied in female rats. The diets used contained either 0.4-0.6% phosphorus and either cellulose (10%, w/w) or pectin. The purified diets used were balanced … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 7,534 accessesView PDF Cite

Research ArticleOpen accessOral Administration of Gelatin Hydrolysate Reduces Clinical Signs of Canine Osteoarthritis in a Double-Blind, Placebo-Controlled TrialA.C. Beynen, H.W. Van Geene, H.V. Grim et al.Problem statement: There are indications that the intake of gelatin hydrolysate has a beneficial impact on the clinical signs of osteoarthritis in dogs. Data from a controlled trial were required to substantiate these indications. Approach: A double-blind, placebo-controlled trial with privately owned dogs was carried out to assess the efficacy of a preparation of gelatin hydrolysate in the treatment of … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 18,245 accessesView PDF Cite

Research ArticleOpen accessInfluence of Dietary Beta-1,3/1,6-Glucans on Clinical Signs of Canine Osteoarthritis in a Double-Blind, Placebo-Controlled TrialA.C. Beynen, E. LegersteeProblem statement: There are indications for a beneficial effect of beta-1,3/1,6-glucans on the clinical signs of dogs with osteoarthritis. Data from a controlled trial were necessary to prove or disprove the indications. Approach: A double-blind, placebo-controlled trial with privately owned dogs was carried out to assess the efficacy of a preparation of beta-1,3/1,6-glucans in the treatment of osteoarthritis. With the … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 10,105 accessesView PDF Cite

Research ArticleOpen accessExposure of Broiler Chickens to a Weak Electromagnetic Field Reduces the Impact of a Simulated, Commercial Eimeria InfectionM.A. Elmusharaf, J.J. Cuppen, H.N.A. Grooten et al.Problem statement: In a previous study, the exposure of broiler chickens to a weak Electromagnetic Field (EMF) reduced the severity of a coccidiosis infection. The birds were infected by gavage into the crop which was not representative for the field situation. Approach: The possible anticoccidial activity of EMF was investigated in broiler chickens with a simulated, commercial coccidiosis infection. There … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,276 accessesView PDF Cite

Research ArticleOpen accessImpact of Dietary Fat Type and Amount on Growth Performance and Serum Cholesterol in RabbitsA. Alhaidary, H. E. Mohamed, A.C. BeynenProblem statement: Literature data on the effect of dietary fat on growth performance in rabbits are inconclusive. For commercial rabbit production it is relevant to know to what extent dietary fat level and type can be manipulated. In the present study serum cholesterol was also analyzed because its relation to the amount and type of dietary fat was not known … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,476 accessesView PDF Cite
