Abstract:
The sheep industry is an important and good development prospects having
confinement, a limiting factor the cost of feeding activity. In this sense makes it
necessary to search for alternative sources of food, which would reduce the high cost of
food and they have availability in the region where the confinement is deployed. The
experiment was conducted in the Department of Sheep industry and Animal Nutrition
Laboratory Campus Patos, Federal University of Campina Grande. Were used 12 Santa
Inês sheep, males, adults, with an average body weight of 20 kg. The animals were fed
total mixed ration composed of 40% concentrate and 60% roughage, designed for a gain
of 200g per day, with treatments consisting of different associations hay Jurema Preta
(FJP) buffel grass (FCB): 0% FJP FCB 100% +, 33% + 67% FJP FCB, 67% + 33% FJP
FCB; FJP 100% + 0% FCB. The diet was fed to provide plenty of 10% and
consumption was assessed by weighing the offered and refuse. Being collected samples
of the diet, the leftovers, the faeces and urine for the chemical analyzes and protein
balance. Nitrogen (N) was quantified in dry matter intake (NI), in feces (NF) and urine
(NU). Was observed a linear decrease effect substitution of FCB by FJP (P> 0.05) for
NI (g/kg PM/day), NU (g/day), NU (g/kg PM/day), NU (% ), NU (g/kg PM/day) and
NA (%).These results may reflect a possible effect of tannin on hay Jurema Preta, which
due to its astringent characteristic.
