Leal, Dyhogo Henrique Veloso; Azevedo, Alcinei Mistico; Almeida, Anna Christina de; Pires Neto, Otaviano de Souza; Duarte, Eduardo RobsonThe purpose of the present study was to evaluate the principal component analysis (PCA) to guide technical assistance regarding several dairy farms’ issues, which includes improving microbiological quality and physical-chemical composition of raw refrigerated milk. Data of monthly analysis of fat, protein, lactose, dry defatted stratum, somatic cell count, total bacterial count, milk temperature of 8,101 sample...
Inbreeding on productive and reproductive traits of dairy Gyr cattle
Reis Filho, João Cruz; Verneque, Rui da Silva; Torres, Robledo de Almeida; Lopes, Paulo Sávio; Raidan, Fernanda Santos Silva; Toral, Fabio Luiz BuraneloThe objective of this study was to estimate genetic parameters and to evaluate the effects of inbreeding on productive and reproductive traits of dairy Gyr cattle. Single-trait animal models were used to estimate genetic parameters and solutions for inbreeding coefficients for milk (milk 305-d), fat (fat 305-d), protein (protein 305-d), lactose (lactose 305-d), and total solids (TS 305-d) yield up to 305 days o...
