Intake and digestibility of diets containing jitirana hay for finishing sheep
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2017, Vol 12, Issue 1
Abstract
Jitirana is found in semiarid region of brazilian northeastern, giving high biomass production and satisfactory nutrient content during the rain season that qualifies as alternative feed for ruminants. Thus, it was evaluated the substitution effect of 0; 25; 50 and 75% of tifton 85 hay to jitirana hay (JH) on intake and digestibility of diets for sheep, randomized in double 4 x 4 latin square design, with eight sheep. Dry matter (DM) and nutrients intake were influenced (P<.05) by JH inclusion, except for neutral detergent fiber (NDF) intake, that was around 682.76 ± 125.13 g per animal per day. DM intake increased linearly (P<.05) raising approximately 6.33 g per unit percentage of JH increased. There was positive linear effect (P<.05) for crude protein (CP) end NDF intake, with an increase of 1.11 g per animal per day and 0.02% of body weight, per unit percentage of JH included. There was a positive effect for NDF digestibility which resulted in linear increase (P<.05) by 0.14%. JH in substitution of tifton 85 hay increases DM and nutrients intake, but does not influence the digestibility, except for NDF digestibility, recommending use of 75% in substitution, which allows satisfactory nutritional requirements for DM and CP intake, and increase the NDF digestibility.
