Resumo: | Colostrums considered of good and very high quality are considered colostrums with a BRIX of ≥25%, so the first weeks of a neonate's life are considered critical, showing a greater susceptibility to diseases. In this sense, the objective was to evaluate the quality of colostrum and the transfer of passive immunity in Holstein heifers. The experiment was carried out on a milk producing property, located in the municipality of Olho D'agua das Flores, Alagoas, from October 2021 to April 2022, where 181 crossbred heifers were used. To measure the quality of the colostrum, an optical Brix refractometer was used, if it showed a quality lower than 25% BRIX, this colostrum was corrected and offered to the calf. The collected blood was stored in a tube without anticoagulant and left to rest until the serum was obtained, later, a drop of this serum was applied to the refractometer prism and, similarly to colostrum, a reading was performed to determine the concentrations of proteins. totals. For Pearson's correlation study, correlation coefficient analysis (r) was performed, assuming intervals of -1 (negative linear association) and 1 (positive linear association). Serum protein showed a negative correlation with the time of colostrum supply after birth (r = -0.16) and positive with calf weight at birth (r = 0.15). The adequate program of colostrum and evaluation of transfer of passive immunity allied to the proper management collaborate for the success in the productive indexes of the properties. |

Neste sentido, objetivou-se avaliar a qualidade do colostro e a transferência de imunidade passiva em bezerras da raça holandesa. O experimento foi realizado em uma propriedade produtora de leite, localizada no município de Olho D’agua das Flores, Alagoas, no período de outubro de 2021 a abril de 2022, onde foram utilizadas 181 bezerras mestiças. Para aferição da qualidade do colostro, utilizou-se o refratômetro de BRIX óptico, caso demonstrasse qualidade inferior a 25% BRIX esse colostro era corrigido e ofertado a bezerra. O sangue coletado foi armazenado em um tubo sem anticoagulante e deixado em repouso até a obtenção do soro, posteriormente, uma gota desse soro foi aplicado ao prisma do refratômetro e, de modo semelhante ao colostro, foi realizado uma leitura determinando-se as concentrações de proteínas totais. Para o estudo de correlação de Pearson foi realizado análise de coeficiente de correlação (r), assumindo intervalos de -1 (associação linear negativa) e 1 (associação linear positiva). A proteína sérica apresentou correlação negativa com o tempo de fornecimento do colostro após o nascimento (r = - 0,16) e positiva com o peso da bezerra ao nascer (r = 0,15). O programa adequado de colostragem e avaliação de transferência de imunidade passiva aliado ao manejo adequado colaboram para o sucesso nos índices produtivos das propriedades.Universidade Estadual de Alagoas - Eduneal2023-04-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliados pelos paresapplication/pdfapplication/pdfhttps://diversitasjournal.com.br/diversitas_journal/article/view/251410.48017/dj.v8i2.2514Diversitas Journal; Vol. 8 No. 2 (2023): Através das lentes: a importância da biodiversidade para o equilíbrio ambiental; 1237-1248Diversitas Journal; Vol. 8 Núm. 2 (2023): Através das lentes: a importância da biodiversidade para o equilíbrio ambiental; 1237-1248Diversitas Journal; v. 8 n. 2 (2023): Através das lentes: a importância da biodiversidade para o equilíbrio ambiental; 1237-12482525-521510.48017/dj.v8i2reponame:Diversitas Journalinstname:Universidade Estadual de Alagoas (UNEAL)instacron:UNEALporenghttps://diversitasjournal.com.br/diversitas_journal/article/view/2514/2085https://diversitasjournal.com.br/diversitas_journal/article/view/2514/2086Copyright (c) 2023 Joyce Ramos da Silva, Maria do Carmo Carneiro, Ariane Loudemila Silva de Albuquerque, Chiara Rodrigues de Amorim Lopeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRamos da Silva, JoyceCarneiro, Maria do CarmoSilva de Albuquerque, Ariane LoudemilaRodrigues de Amorim Lopes, Chiara2023-10-26T10:14:19Zoai:ojs.diversitasjournal.com.br:article/2514Revistahttps://diversitasjournal.com.br/diversitas_journal/indexPUBhttps://www.e-publicacoes.uerj.br/index.php/muralinternacional/oairevistadiversitasjournal@gmail.com2525-52152525-5215opendoar:2023-10-26T10:14:19Diversitas Journal - Universidade Estadual de Alagoas (UNEAL)false |
