Résumé:
The dissertation includes two articles related to digestive system disease. The first refers to a field
research whose objective was to detect changes in the homeostasis of the horse organism affected
by colic syndrome seen at the Veterinary Hospital of the Rural Health and Technology Center of the
Federal University of Campina Grande (HVU/CSTR/UFCG), Campus Patos - PB between the
period of 2018 to 2019. 32 animals from the clinical routine were used, divided into two groups: In
G1 animals with colic by compaction and G2 with other types of colic, in both groups variables
such as sex, range age and degree of dehydration. A percentage of 46.9% of the animals was
diagnosed with colic by compaction, with colons being the most affected areas. In the group at the
biochemical level, a hypoglycemia was found and justified by a prolonged fasting to which the
animals were submitted after suspected colic still in its place of origin. The reduction in electrolyte
levels was detected, being directly related to the compaction itself and in procedures related to
colic. In the second article, clinical records of horses treated from June 2009 to June 2019, HVU /
CSTR / UFCG, were reviewed. A total of 3.241 horses were treated, of which 262 were diagnosed
with colic syndrome (8.1%). The most common cases were colon compaction, gastric overload, gas
colic, spasmodic colic, displacement of pelvic flexure, gastritis, mesentery torsion, enteritis,
displacement of the large colon and displacement of the cecum. Colic horses were 2.16 times more
likely to die than if they were affected by another disease. In this research, a lethality of 35.9% was
observed, showing a decline compared to a study carried out between 2001 and 2010 in the local
referent in the current research, whose lethality was 61.4%. Among the variables studied, the treated
water was significant for triggering colic. The presence of grass in the diet leads to 1.59 times more
chance of colic, due to the wrong supply, as well as the poor quality of the fiber. It is concluded that
the colic syndrome represents a great impact on the equidoculture of the backlands of Paraíba due to
its complexity that leads to a high degree of lethality, with numerous factors associated with its
development, among them the grass-based diet the main elephant grass (Pennisetum purpureum),
brachiaria (Brachiaria spp.), sorghum (Sorghum spp.), Tifton 85 (Cynodon spp.) and Buffel
(Cenchrus ciliaris).
