Efeitos da fibra dietética extrusada na alimentação de matrizes suínas em gestação / Effects of extruded dietary fiber in the diet of gestating sows

This work was based on the experiment in which forty-four newly weaned pig matrices with the same birth order and age were used, equally distributed in two experimental groups where they received two different treatments, with and without an increase of 15% of extruded fiber along gestational period. Collections and analysis of zootechnical data were performed at 40, 65, 87, 107 days of gestation, and after 21 days of piglets. The main objectives proposed were achieved with satisfaction, which were to maintain the batch uniformity (body score close to 3), ideal fecal score, reduction of stereotypes caused by the sensation of hunger, and increase in the number of piglets born alive and consequently weaned. The swine matrices, besides having been submitted to the animal welfare precepts, characterizing a healthier creation, still presented an increase of 1.95 more piglets per parturition.

Weaned Pig

Feed intake in the days immediately following weaning is both low and variable. This period is critical as low food intakes can lead to reduced digestive efficiency and suboptimal animal welfare. This is of commercial importance as performance around weaning has been shown to impact on the number of days an animal takes to reach a given slaughter weight (Mahan and Lepine 1991). If the variation in an individual’s performance could be characterised in terms of feeding behaviour and/or social status then production systems could be designed to optimise growth. In this trial liveweight gain during the late suckling period and liveweight gain, familiarity with penmates and social status (as determined by weight) after weaning were analysed to assess their impact on the performance of the post weaned pig.

Otoconia are microscopic geometric structures that cover the sensory epithelia of the utricle and saccule (gravitational receptors) of mammals, and the lagena macula of birds. The importance of otoconia for maintanance of the body balance is evidenced by the abnormal behavior of species with genetic defects of otolith. Although a few reports have dealt with otoconia formation, some basic questions remain unanswered. The chick embryo is desirable for studying otoconial formation because its inner ear structures are easily accessible, and its gestational period is short (21 days of incubation).The results described here are part of an intensive study intended to examine the morphogenesis of the otoconia in the chick embryo (Gallus- domesticus) inner ear. We used chick embryos from the 4th day of incubation until hatching, and examined the specimens with light (LM) and transmission electron microscopy (TEM). The embryos were decapitated, and fixed by immersion with 3% cold glutaraldehyde. The ears and their parts were dissected out under the microscope; no decalcification was used. For LM, the ears were embedded in JB-4 plastic, cut serially at 5 micra and stained with 0.2% toluidine blue and 0.1% basic fuchsin in 25% alcohol.

Production Conditions

Innovators of in vitro meat (IVM) are convinced that this approach is the solution for problems related to current meat production and consumption, especially regarding animal welfare and environmental issues. However, the production conditions have yet to be fully clarified and there is still a lack of ethical discourses and critical debates on IVM. In consequence, discussion about the ethical justifiability and desirability of IVM remains hypothetical and we have to question those promises. This paper addresses the complex ethical aspects associated with IVM and the questions of whether, and under what conditions, the production of IVM represents an ethically justifiable solution for existing problems, especially in view of animal welfare, the environment, and society. There are particular hopes regarding the benefits that IVM could bring to animal welfare and the environment, but there are also strong doubts about their ethical benefits.
