| Objetivou-se neste trabalho avaliar a seletividade e a eficiência de herbicidas no controle de plantas daninhas na cultura da alfafa. Foram desenvolvidos dois experimentos em Anápolis, GO. No primeiro, avaliaram-se oito herbicidas (imazethapyr, MSMA, fomesafen, bentazon, chlorimuron-ethyl, imazamox) aplicados em pós-emergência da alfafa, e no segundo, seis misturas de herbicidas [(diuron + MSMA), (diuron + MSMA), (diuron + paraquat), (diuron + paraquat)] aplicados um dia após o corte da alfafa. Em ambos os experimentos, foram incluídas duas testemunhas (capinada e sem capina), sendo os tratamentos distribuídos em blocos ao acaso com quatro repetições. Os herbicidas como imazethapyr, MSMA, fomesafen, bentazon, chlorimuron-ethyl e imazamox foram seletivos à... |

| Abstract: The objective of this work was to determine the genotypic profile specific to scrapie in codons 136, 154, and 171 of the PRNP gene of the Pantanal creole sheep. Genomic DNA was extracted from blood samples collected from 66 sheep, and the regions of interest on the DNA strand were amplified by PCR. Five haplotypes were identified: ARR, alanine, arginine, arginine; ARQ, alanine, arginine, glutamine; AHQ, alanine, histidine, glutamine; ARH, alanine, arginine, histidine; and VRQ, valine, arginine, glutamine. The most common genotypes were ARQ/ARQ (27%) and ARR/ARQ (24%). The genotypic profile of the Pantanal creole sheep shows low to moderate susceptibility. |

| The objective of this study was to evaluate the influence of crossings between sheep breeds on the intrinsic quality of leather. It was used the skins of 36 lambs (18 females and 18 males), resulting from crosses between ewes of a native breed from the Brazilian state of Mato Grosso do Sul and rams of the same native breed as well as the Texel and Santa Inês genetic groups. The animals were raised in confinement until slaughter weight, from 28 to 32 kg. After slaughter, samples were taken from the skins for histological analysis. The skins were tanned with chromium, retanned and greased. It was taken from the leather samples for electromicrographs and for tests for tensile and tear strength (intrinsic quality). Morphological aspects from the skin as well... |
