Summary: | The crossbreeding between dairy cow breeds has been used as an alternative to improve some characteristics such as milk composition, udder health, and reproductive aspects on dairy herds. The aim was to compare growth, milk yield and composition, and mammary gland health of crossbred Holstein x Simmental and purebred Holstein cows. Data were gathered from a farm located in Santa Catarina state, south of Brazil. Cow growth was assessed by weighing calves and heifers monthly. Yet for milk yield and udder health, data were taken from records of the official Dairy Herd Improvement Program carried out in the evaluated farm. These data were subjected to variance analysis using the MIXED procedure of SAS statistical software. Non-linear regressions were used to adjust the data to the growth curves. The crossbred Holstein x Simmental cows produced more milk than did purebreds (31.8 kg/day vs. 30.4 kg/day; p < 0.05), with higher contents of lactose (4.63% vs. 4.53%) and protein (3.14% vs. 3.03%), but no differences in fat content (3.00 vs. 2.96). Purebred cows had higher somatic cell score (SCS) 4.49 vs. 2.93 (P < 0.0001). Furthermore, no differences were found for the growth of calves and heifers. In conclusion, crossbred Holstein x Simmental cows have higher energy corrected milk as the Holstein ones, whit greater uncorrected milk yield only for cows with three or more lactations. Crossbreeds cows produce milk with better quality, indicated by lower SCS and higher solids content, besides showing a lower SCS and no differences regarding weight gain of calves and heifers. |

O objetivo foi comparar o crescimento, produção e composição do leite e sanidade da glândula mamária de vacas mestiças Holandês x Simental e vacas puras Holandês. Os dados foram obtidos em uma fazenda em Santa Catarina, sul do Brasil. Crescimento de bezerras e novilhas foi estimado pela pesagem mensal dos animais. Informações sobre produção e composição do leite e sanidade de glândula mamária foram obtidos dos relatórios de controle leiteiro oficial. Os dados foram submetidos análise de variância usando o procedimento MIXED do pacote estatístico SAS. Regressões não lineares foram usadas para gerar curvas de crescimento. Vacas mestiças Holandês x Simental produziram mais leite que vacas puras Holandês (31,8 kg/dia vs. 30,4 kg/dia; p < 0,05), com maior teor de lactose (4,63% vs. 4,53%) e proteína (3,14% vs. 3,03%), mas sem diferença para teor de gordura (3,00 vs. 2,96). Vacas puras Holandês apresentaram maior escore de células somáticas (ECS) 4,49 vs. 2,93 (P < 0,0001). Além disso, não houve diferença para crescimento de bezerras e novilhas. Conclui-se que, vacas mestiças Holandês x Simental, produziram mais leite corrigido para energia e proteína em relação as vacas Holandês, com maior produção de leite não corrigido apenas para vacas com três ou mais partos. Vacas mestiças produzem leite com mais qualidade, indicado pela baixa ECS e o maior teor de sólidos, sem diferença para crescimento de bezerras e novilhas.UEL2018-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionresearchapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3121610.5433/1679-0359.2018v39n6p2597Semina: Ciências Agrárias; Vol. 39 No. 6 (2018); 2597-2606Semina: Ciências Agrárias; v. 39 n. 6 (2018); 2597-26061679-03591676-546Xreponame:Semina.
