    Refinando a avaliação bioclimática do estado de Pernambuco para a criação de vacas leiteiras
    (2021) Oliveira, Gabriela Mayara Pereira; Silva, Thieres George Freire da; http://lattes.cnpq.br/0213450385240546; http://lattes.cnpq.br/6833841784894704
    The Brazilian Northeast has shown significant growth in dairy cattle, which has contributed to the improvement of the economy. In this context, the objective was to improve the bioclimatic assessment of the state of Pernambuco for the creation of dairy cows through the application of bioclimatic risk, and multivariate statistics. Meteorological data from 13 to 20 years from 14 municipalities in the state of Pernambuco were used. From the meteorological data, bioclimatic indices were generated, such as ITU, DPL, RCA, TGN, ITGU, and CTR, as well as the bioclimatic risks for levels 10, 15, 20, 25, 30, and 35 kg of animal milk-1 day-1 . A principal component analysis was carried out with bioclimatic indices and animal performance to verify the capacity and the discriminative relationship of the variables in each season of the year. The four principal components were responsible for explaining 85.70% (summer), 88.75% (autumn), 93.06% (winter), and 85.70 (spring) of the total variation of the data sets. The municipalities of Arcoverde and Caruaru were the only ones that showed a negative correlation with the indices of DPL, RCA, CTR, TGN, ITGU, and bioclimatic risk, which qualify as places of significant potential for the implantation of a dairy in the state of Pernambuco
