Item Influência do estresse causado pela tosquia e aumento de peso ao nascer de cordeiros(Centro Universitário da Fundação de Ensino Octávio Bastos, 2007-09-30) MORINI JÚNIOR, João Carlos; MORINI, Adriana Caroprezo; FRANCIOLLI, André Luis Rezende; FAVARON, Phelipe Oliveira; WENCESLAU, Cristiane Valverde; RIBEIRO, Luiz Alberto Oliveira; MANÇANARES, Celina de Almeida Furlanetto; MIGLINO, Maria Angélica; BOMBONATO, Pedro PrimoReproductive losses in the southern region of Brazil have been a major problem for sheep farmers and studies in the area report that the weight of lambs at birth when greater than 4Kg allows it to survive during the winter period in which they are born. Due to the need for greater weight at birth, to ensure greater survival, numerous procedures have been performed in an attempt to promote lower mortality. The purpose of this work was to verify the influence of shearing on transplacental glycogen transport and its supposed relationship with the increase in birth weight in lambs (Ovies aries). For the realization of the project 9 sheep of the Australian Merino breed were used which were raised at the Federal University of Rio Grande do Sul - Porto Alegre / RS) - UFRGS in collaboration with the Lutheran Brazilian University - ULBRA. The animals were divided into 2 groups: the first with 5 sheared animals (OVE) at 70 days of the perinatal period and the second with four animals that were kept as control (OVC). The fetuses were collected through a surgical cesarean section performed at the end of pregnancy. For comparative purposes, placental and fetal weight were initially measured; to characterize the placenta, the number of placentons and the length, width and thickness of the placentonium were quantified, with the aid of a caliper. The collected placental material was fixed, dehydrated, diaphanized and included in paraffin, for later making slides and quantifying glycogen. As a partial macroscopic result, the placentas of the sheep in the sheared group had a weight 13% greater than those in the control group, in the fetuses the difference was more expressive, the weight of the fetuses sampled in the sheared group was 25% greater than those in the second group. The differences between the measures of thickness, length and width were insignificant, but always with higher rates in the tested group.Item Caracterização da morfologia externa de fetos de Paca(Centro Universitário da Fundação de Ensino Octávio Bastos, 2007-09-30) FRANCIOLLI, André Luis Rezende; AMBRÓSIO, Carlos Eduardo; MARTINS, Daniele dos Santos; MANÇANARES, Celina Almeida Furlanetto; CARVALHO, Ana Flávia de; WENCESLAU, Cristiane Valverde; COSTA, Gerlane M.; MORINI JÚNIOR, João Carlos; MORINI, Adriana Caroprezo; MIGLINO, Maria AngélicaThe present scientific investigation aimed to study the embryonic development of pacas (Agouti Paca), with a view to the external morphological description of fetuses. Five fetuses were used, three of which were donated from the donation maintained by the Faculty of Agricultural and Veterinary Sciences of Jaboticabal - UNESP and two donated from the collection of biological material from FMVZ - USP. Fetuses 1 and 2 with 5.7 and 6.8 cm of Crow Rump, respectively, presented as morphological characteristics: marked facial immaturity, with the eyes covered by a prominent lens; the earlobes had a low level of development. The mouth had a small opening, where the formation of the incisor teeth was observed. Fetuses 3 and 4 with 9.6 and 10.5 cm of Crow Rump, respectively, showed well-developed ears, thoracic and pelvic limbs were in an equal degree of development with the presence of claws and development of facial features, like vibrissae around the nasal edges, the eyes remain protected by a prominent lens and the mouth contained the incisor teeth in an intermediate stage of development. Fetus 5, with 15.5 cm of Crow Rump, presented as a striking feature, the body covered by hair, thoracic and pelvic limbs in an equal degree of development with claws, development of facial characteristics, such as vibrissae, prominent eyes and well-developed ears. In all fetuses, the genital tubercle and the anal rim can be seen in the perineal region.
