The objective of this study was to compare EBVs, reliability and genetic parameters in random regression models with Legendre polynomials using structures of data sets with different minimum number of test days in lactation. The original data base was edited in order to prepare for subsets by deleting cows that did not have at least 4, 6, 8 or 10 test day (TD) records in lactation. The original intervals between monthly TD were used. Random regression models with third (M3), fourth (M4) and fifth-order (M5) Legendre polynomial were used. The lowest values of AIC, BIC, −2LogL and RV was found in the models with highest Legendre polynomials orders within structure with 6, 8 and 10 TD and lowest in structure with 4 TD. The eigenvalues indicated models with lowest Legendre polynomial orders as M3 and M4 in all structures. Heritability on days in milk ranged from 0.24 to 0.48 for M3 and from 0.17 to 0.31 for M4 and M5. Spearman correlations of EBVs of bulls and cows between M3, M4 and M5 were higher than 0.99 in all structures. Average reliability of EBVs of a group of bulls in common was around 0.82, 0.82, 0.80 and 0.63 in structures with at least 4, 6, 8 and 10 TD, respectively. Results indicate M3 and M4 as sufficient for genetic evaluations in all data sets of Holstein cattle. Random regression models will have similar reliability and ranks of EBVs in data sets with a minimum of 4, 6 or 8 TD. |

The role of Escherichia coli in healthy microbiota of psittacine is controversial, and the presence of Salmonella sp. indicates possible disease. Therefore, this study aimed to identify the presence of E. coli and Salmonella spp. in a psittacine pet that died in Fortaleza, Brazil, correlating pathogenicity aspects of the isolates through the evaluation of lesions and antimicrobial susceptibility. Psittacine pets sent to the Laboratory of Ornithological Studies, State University of Ceará, that died in 2014 and 2015 were necropsied. Fragments of liver, kidneys, intestine, lung, heart, spleen and brain were collected for microbiological and histopathological analyses. Scores were attributed to lesions and isolated strains submitted to antimicrobial susceptibility test. From the seventy necropsied birds, nineteen were positive for E. coli and one for Salmonella Typhimurium. Congestive lesions and lymphoplasmocitic inflammatory infiltrate were observed varying from light to moderate and were the main findings. In the analyzed strains, multidrug resistance against different groups of antibiotics was observed. In conclusion, according to the results, E. coli strains and the Salmonella Typhimurium isolate produced significant lesions in the psittacine pets, and multidrug resistance may hinder treatments with antibiotics used in avian pet medicine. |
