Effects of Saccharomyces cerevisiae and monensin on digestion, ruminal parameters, and balance of nitrogenous compounds of beef cattle fed diets with different starch concentrations
This study was carried out aiming to evaluate the effects of yeast or monensin supplementation on dry matter intake, nutrients digestibility, ruminal volatile fatty acids profile, ruminal pH and ammonia concentration, microbial protein synthesis, and the balance of nitrogen compounds of cattle fed h...

Effects of Saccharomyces cerevisiae and monensin on digestion, ruminal parameters, and balance of nitrogenous compounds of beef cattle fed diets with different starch concentrationsIonophoreFeed additivesFeedlot YeastThis study was carried out aiming to evaluate the effects of yeast or monensin supplementation on dry matter intake, nutrients digestibility, ruminal volatile fatty acids profile, ruminal pH and ammonia concentration, microbial protein synthesis, and the balance of nitrogen compounds of cattle fed high concentrate diet (80 % dry matter (DM) basis) with two different levels of starch. Eight crossbred beef steers fitted with rumen cannula were assigned to two simultaneous 4 × 4 Latin squares arranged in a 4 × 2 factorial design. Two different starch levels (23 and 38 % of DM) were assigned to each Latin square, independently. Within each Latin square, four treatments were randomly assigned to the experimental animals (control; monensin; 1-g yeast [1 g/100 kg body weight (BW)/day] treatment; and 2.5-g yeast [2.5 g/100 kg BW/day] treatment). Feed additives did not influence ruminal pH (P > 0.05). Total ruminal volatile fatty acids (VFA) concentration was greater (P < 0.05) in the diet with the lowest starch level. Similarly, monensin and 1-g yeast treatments resulted in greater (P < 0.05) VFA concentration in the rumen. Monensin inclusion in the diet with the highest starch level led to a decrease (P < 0.05) in lactate concentration in the rumen. However, acetate levels were increased (P < 0.05) by the inclusion of 1 g of yeast in the diet with lowest starch level. Ruminal concentrations of propionate and butyrate, and ammonia-N were not influenced (P > 0.05) by none of the additives evaluated. However, propionate concentration was greater (P < 0.05) in the low-starch diets. Low-starch diets resulted in lower ruminal ammonia-N concentration and greater neutral detergent fiber digestibility (P < 0.05). The excretion of urinary nitrogenous compounds, purine derivatives, synthesis of microbial protein, microbial efficiency, and balance of nitrogenous compounds were not affected by treatments evaluated (P > 0.05). Monensin or yeast inclusion in high concentrate beef cattle diets in tropical regions as in Brazil is not justified by do not alter nutrient digestibility, nitrogen balance, and main ruminal parameters.Tropical Animal Health and Production2017-11-14T09:25:49Z2017-11-14T09:25:49Z2013-03-05info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1573-7438http://dx.doi.org/10.1007/s11250-013-0356-9http://www.locus.ufv.br/handle/123456789/13013engVolume 45, Issue 5, p. 1251–1257, June 2013info:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFVMonnerat, João Paulo Ismério dos SantosPaulino, Pedro Veiga RodriguesDetmann, EdenioValadares Filho, Sebastião CamposValadares, Rilene Diniz FerreiraDuarte, Márcio Souza2024-07-12T06:40:09Zoai:locus.ufv.br:123456789/13013Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:40:09LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false |
