Résumé:
Nutritional deficiencies associated with incorrect sanitary practices make animals more
likely to develop disease. The sanitary commitment becomes more eminent in the
period of peripartum of dairy goats, which in this period become more prone and
sensitive to develop diseases of metabolic, nutritional and infectious nature. At this
stage, hormonal and metabolic changes are necessary to meet the demands of
maintaining organic activities, gestation, delivery and lactation, resulting in greater
attention to the producer for the correct management of these animals, whose
deficiencies can result in losses linked to Milk production, replenishment of animals or
even death. This dissertation was divided into two chapters. The first one was submitted
to the Brazilian Archive of Veterinary Medicine and Animal Science, evaluating the
metabolic profile of dairy goats in the peripartum, created in the micro region of
Western Cariri Paraiba. The animals were evaluated from the 30 days before delivery,
on the day of delivery and up to 41 days of lactation. Measurements were performed in
relation to the mineral, energetic, proteic and enzymatic aspects of metabolism. At the
time of calving there was a significant reduction (P<0,05) in variables such as total
calcium, phosphorus, total proteins, globulins, cholesterol and in the elevation of AGNE
values. Glucose reduction and urea increase were recorded from 32 to 41 days of
lactation. In the second chapter, submitted to Acta Scientiae Veterinariae, the nutritional
and parasitic management of goats during the transition period, from 20 days before
calving, at calving and up to 35 days of lactation, were evaluated. Metabolites linked to
the mineral, energetic, proteic and enzymatic profile were measured, as well as
parasitological evaluation by means of OPGs and body weight variation. Values of total
calcium, ionized calcium, magnesium and albumin obtained a significant reduction (P
<0,05) at delivery. There was a significant increase (P<0,05) in glucose at calving,
which resulted in a significant increase (P<0,05) in fructosamine soon afterwards.
Triglyceride values were higher in the prepartum, registering higher values between 13-
1 days prepartum, where the highest serum peak of urea was recorded. GGT showed
upward behavior, with a significant increase (P<0,05) during lactation with peak serum
in 14-22 days postpartum. Goats recorded greater elimination of eggs and oocysts in the
prepartum, with maximum values of OPGs close to calving (13-1 dap). Note the
importance of the nutritional level for peripartum matrices, a crucial aspect for the good
attendance to physiological demands and coping with gastrointestinal parasitoses.
