Parasitosis gastrointestinal and hematocrit value in ewe fed with different levels of crude protein

Abstract

We evaluated the parasitological behavior of sheep females fed with different levels of crude protein, by the value of hematocrit and egg counts per gram of feces (EPG) in identifying severely infected animals. Were used 47 female sheep of Santa Ines, Texel and Ile de France, aged between eight and 12 months, wormed 30 days before the first data of crops, which were held every two weeks. Within each race, the animals were divided into two treatments, deferred by 12% or 16%, crude protein in the diet. It is obtained, laboratory, the value of hematocrit of each animal and the amount of EPG. The value of hematocrit showed a variation (28.5 a 34.0) throughout the experimental period, arising from changes (800 a 5400) of EPG values. No differences were identified for EPG and hematocrit levels between 12 and 16% of PB. Diet recommendation with 12% crude protein, by inferring lower commercial cost in feed.
