Resumo: | The objective of this study was to evaluate the use of crude glycerin as an energetic supplement in the diet for lactating cows kept in a ryegrass (Lolium multiflorum) system. Eighteen Holstein cows were used in a experiment carried out at Regional Institute for Rural Development in Augusto Pestana, RS, Brazil, distributed in a block design (according to the days in lactation) in a simple reversion scheme, in three periods of 14 days each on. The diets were composed of grazing ryegrass, supplemented with corn silage and concentrate, with or without 10% crude glycerin on a total dry matter basis (DM). Samples of food and milk were collected and analyzed. Data were submitted to analysis of variance and the effect of treatment compared by the T test through the SAS statistical program. The inclusion of GB does not affect milk production and composition. The sum of saturated fatty acids (ΣAGS) and caprylic, capric and lauric acids were significant (P <0.05) in relation to the control group, increasing their values with the inclusion of crude glycerin in the diet. In relation to the monounsaturated acids the oleic acid the values were heigher when glycerin was not established in the diet (control group), as well as the sum of monounsaturated fatty acids (ΣAGMI). Polyunsaturated fatty acids did not differ between treatments (P> 0.05). We conclued that the inclusion of crude glycerin in the diet of dairy cows does not affect milk production or milk quality and is a good option for energy supplementation. |

As dietas foram constituídas de azevém em pastejo, suplementado com silagem de milho e concentrado, acrescido (grupo tratado) ou não (grupo controle) de 10% de glicerina bruta com base na matéria seca (MS) total. Foram coletadas e analisadas amostras de alimentos e leite. Os dados foram submetidos à análise de variância e o efeito de tratamento comparado pelo teste T através do programa estatístico SAS. Verificou-se que a inclusão de glicerina bruta não afeta a produção e a composição do leite. O somatório de ácidos graxos saturados (ΣAGS) e os ácidos caprílico, cáprico e láurico obtiveram significância (P<0,05) em relação ao grupo controle, aumentando seus valores com a inclusão de glicerina bruta na dieta. Dos ácidos monoinsaturados, o oleico foi o que apresentou significância (P<0,05), aumentando os valores quando a glicerina não foi instituída na dieta (grupo controle), assim como o somatório dos ácidos graxos monoinsaturados (ΣAGMI). Os ácidos graxos poliinsaturados não diferiram entre os tratamentos (P>0,05). Conclui-se que a adição de glicerina bruta na dieta de vacas leiteiras não afeta a produção de leite ou a qualidade do mesmo, sendo uma boa opção de suplementação energética. Para a composição de ácidos graxos, o uso da glicerina bruta afetou indesejavelmente os índices de ácidos saturados.porUniversidade Federal de Santa MariaCentro de Ciências RuraisPrograma de Pós-Graduação em ZootecniaUFSMBrasilZootecniaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessGlicerina brutaLeiteÁcidos graxosGlycerin crudeMilkFatty acidsCNPQ::CIENCIAS AGRARIAS::ZOOTECNIAProdução, análise química e perfil de ácidos graxos do leite de vacas em pastagem de azevém suplementadas com glicerina brutaProduction, chemical analysis and profile of fatty milk from vegetation cows in azevém pasture supplemented with crude glycerineinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisViégas, Juliohttp://lattes.cnpq.br/6750187644177333http://lattes.cnpq.br/1252443045127710Nornberg, José Laertehttp://lattes.cnpq.br/1252443045127710Pereira, Emerson Andréhttp://lattes.cnpq.br/5851413155070841http://lattes.cnpq.br/4730276513275842Kleemann, Ana Paula Huttra500400000002600ed59cae3-710d-40c1-b98a-67096b4529b571128b93-9fb7-45f0-92d3-bf3d568924379187891d-4dd1-4037-8061-2b76bdac9be6fcd7e238-a340-403a-afed-d3b254412f6creponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALKleemann, Ana Paula Huttra.pdfKleemann, Ana Paula Huttra.pdfDissertação de Mestradoapplication/pdf1114669http://repositorio.ufsm.br/bitstream/1/11764/1/Kleemann%2c%20Ana%20Paula%20Huttra.pdfac37fdf8e89f7d4258804ca2f9094456MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

The objective of this study was to evaluate the use of crude glycerin as an energetic supplement in the diet for lactating cows kept in a ryegrass (Lolium multiflorum) system. Eighteen Holstein cows were used in a experiment carried out at Regional Institute for Rural Development in Augusto Pestana, RS, Brazil, distributed in a block design (according to the days in lactation) in a simple reversion scheme, in three periods of 14 days each on. The diets were composed of grazing ryegrass, supplemented with corn silage and concentrate, with or without 10% crude glycerin on a total dry matter basis (DM). Samples of food and milk were collected and analyzed. Data were submitted to analysis of variance and the effect of treatment compared by the T test through the SAS statistical program. The inclusion of GB does not affect milk production and composition. The sum of saturated fatty acids (ΣAGS) and caprylic, capric and lauric acids were significant (P <0.05) in relation to the control group, increasing their values with the inclusion of crude glycerin in the diet. In relation to the monounsaturated acids the oleic acid the values were heigher when glycerin was not established in the diet (control group), as well as the sum of monounsaturated fatty acids (ΣAGMI). Polyunsaturated fatty acids did not differ between treatments (P> 0.05). We conclued that the inclusion of crude glycerin in the diet of dairy cows does not affect milk production or milk quality and is a good option for energy supplementation. |
