Resumo: | The objective of this study was to evaluate the effect of the type of milking and the environment on raw milk quality by identification of Somatic Cells Count - CCS in the samples obtained from farms in the mesoregion of south goiano and correlate it with the different types of milk, milk components, and time of year. The research was developed in 229 farms associated with the Catalão Cooperative, divided for types of milking: manual and mechanical. A monthly sample was collected in each property in the expansion tank, totaling 8244 samples. Mechanical milking presented the highest number of samples with CCS > 500.000 cells / mL. There was a positive correlation between CCS and fat and total solids - TS, but there was a negative correlation between CCS and protein and lactose. During the rainy season CCS increased compared to dry season. Also, the rise of temperature and humidity index - THI caused a reduction in fat and TS. In conclusion, hand milking was more feasible to obtain the milk CCS parameters required by the legislation and CCS and milk components suffer interference from the time of the year.Keywords: Environmental indices; Hand milking; Mechanical milking; Subclinical mastitis |

A pesquisa desenvolveu-se em 229 fazendas associadas à Cooperativa de Catalão, divididas por tipo de ordenha: manual e mecânica. Em cada propriedade foi coletada amostra mensal no tanque de expansão, no total de 8244 amostras. A ordenha mecânica obteve maior número de amostras com CCS > 500.000 células/mL. Existiu correlação positiva entre CCS e teor de gordura e sólidos totais - ST, porém houve uma correlação negativa entre CCS e teores de proteína e lactose. No período da chuva tem-se uma elevação de CCS se comparado ao período da seca, e com a elevação do Índice de Temperatura e Umidade - ITU ocorreu uma redução nos teores de gordura e ST. Pode-se concluir que a ordenha manual mostrou-se mais viável para obtenção do leite com parâmetros de CCS exigidos pela legislação e que CCS e componentes do leite sofrem interferência da época do ano.Palavras-chave: Índices ambientais; Mastite subclínica; Ordenha manual; Ordenha mecânicaUniversidade Federal de Goiás2018-08-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/e-3463510.1590/cab19034635Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 19 (2018): Continuous publication; 1-16Ciência Animal Brasileira / Brazilian Animal Science; v. 19 (2018): Publicação contínua; 1-161809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/e-34635/25957https://revistas.ufg.br/vet/article/view/e-34635/25958Cassiano Silva, JulianaCarlos Antunes, Robsoninfo:eu-repo/semantics/openAccess2023-03-23T18:50:39Zoai:ojs.revistas.ufg.br:article/34635Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:56:10.079839Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true |
