    Studies related to animal production and reproduction aim to minimize economic losses, since the number of lambs born and weaned per female / year is directly related to the productive efficiency of the herd. In this way, the greater the amount of lambs born and weaned by sheep, the greater number of animals for sale, for replacement of matrices and for the selection of the flock. The present study aimed to evaluate lambs' weight gain in three different types of weaning management, which were: the precocious, the mixed system and exclusive breastfeeding. Among the types of management mentioned in the experiment, the mixed management group was the one that demonstrated greater advantages in relation to the others.

    Técnica para cateterização do espaço subaracnóideo em ovinos
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2007-09-30) BOCHINI, João Carlos; ALVES, Jeferson Douglas Soares; SILVA, Angélica do Rocio Carvalho; NABI, Mariana Sintoni; DEFAVARI JÚNIOR, Antônio Carlos; FELICIO, Luciano Freitas; PANATTONI, João Flávio; HUCKE, Érica Engelberg Teixeira da Silva
    Techniques for collecting cerebrospinal fluid (CSF) in some animal species have been used for some time. However, the existing techniques present restrictions, both methodological and for animal welfare, which need to be minimized. In this way, 6 multiparous sheep (Ovis aries) of the Santa Inês breed were used to obtain CSF through a puncture of the subarachnoid space with the aid of an epidural catheter between the cervical vertebrae C1 and C2 fixed on the epidermis. After anesthetic recovery of the animals, CSF was harvested for 5 consecutive days. 3 ml of CSF were obtained per animal / day. Throughout the experimental period, the sheep did not show neurological changes, nor a sign of infection, as well as no changes in the CSF's physical characteristics. We conclude that the method for catheterization of the subarachnoid space presented above is feasible and effective for obtaining continuous CSF for prolonged periods, thus avoiding more invasive methods with the same objective.
