MicroRNAs are a class of naturally occurring non-coding RNAs. Typically they are $22 nucleotides long and suppress translation of their targets genes. Several laboratories have attempted to identify miRNAs from pig muscle and the bioinformatics strategies using ESTs have proved to be successful for this aim. In this study we report an in silico identification of ncRNA in pig EST libraries focusing on novel pig ...
A associação entre os alelos do loco BoLA-DRB3.2, identificados pela técnica de PCR-RFLP, e a produção de leite na raça Gir foi estudada por meio da análise de dados moleculares e fenotípicos de 424 vacas Gir, utilizando um modelo misto, sob modelo animal. Os dados moleculares consistiam dos genótipos dos animais para os alelos do loco BoLA-DRB3.2 e os dados fenotípicos eram referentes à produção de leite em at...
The aim of this study was to evaluate the effect of dietary lysine on performance, protein deposition and respiratory chain gene expression in male broilers. A total of 252 Cobb 500 broilers were distributed, in a completely randomized design, into four treatments with seven replicates of nine birds per experimental unit. Experimental treatments consisted of diets based on corn and soybean meal, with four level...

Follicular dynamics and the expression of candidate genes using real-time polymerase chain reaction (PCR) were compared during the oestrous cycle of pig breeds with high (commercial line; n = 24) and low (local Brazilian Piau; n = 21) ovulation rates and prolificacy. Gilts were killed on Days 0, 4, 10 and 18 of the oestrous cycle and visible ovarian follicles were classified by follicular diameter. Recovered cu...
