Resumo: | This work aimed to evaluate the effects of inclusion of bakery waste (BW) in sheep diets on intake, apparent digestibility, balance of nitrogen compounds and ruminal parameters, and determine the carbohydrates and nitrogenous fractions of food and diets. Five levels of corn replacement by BW (0, 25, 50, 75 and 100%) were studied, using five male lambs with live weight of 30 kg, in a Latin square 5 X 5 design. The experimental diets were composed of concentrate and hay Tifton 85 (Cynodon spp) in a forage:concentrate ratio of 60:40. To determine the intake and digestibility were collected samples of food, orts and feces. Urine was collected in buckets for a period of 24 hours to determination of nitrogen balance. Data were interpreted with to variance analysis and regression, using the t test at 5% significance. The BW present higher value for the non fiber carbohydrate and protein fraction with fast ruminal degradation (A+B1), which brought a greater proportion of these fractions in diets replacing 100% of corn by the BW and greater timing of energy supply and protein in the rumen. There wasn t effect (P>0.05) levels of substitution of intake, digestibility of nutrients, balance of nitrogen compounds and weight gain. Different levels of substitution didn t affect (P>0.05) pH values and concentrations of volatile fatty acids, but for the concentration of ammonia nitrogen (N-NH3) was found linear reduction (P<0.05) with the level of replacement, in which each 1% BW promoted reduction of 0,11 mg/dL in the concentration of N-NH3, which may be related to increased ruminal availability of energy, which allows greater use of ammonia for microbial growth. The addition of BW caused a reduction of 51,15% in the cost of ration. It was concluded that the BW can replace the corn in concentrate rations for sheep. |

Foram estudados cinco n?veis de substitui??o do milho pelo RP (0; 25; 50; 75 e 100%), utilizando-se cinco cordeiros machos, com peso m?dio de 30 kg, distribu?dos segundo um delineamento em Quadrado Latino 5 x 5. As dietas experimentais foram compostas de concentrado e feno de capim-Tifton 85 (Cynodon spp), numa rela??o volumoso:concentrado de 60:40. Para a determina??o do consumo e digestibilidade aparente foram coletadas amostras dos alimentos, sobras e das fezes. Foram realizadas coletas de urina por um per?odo de 24 horas para a determina??o do balan?o de compostos nitrogenados. Os resultados foram interpretados de acordo com a an?lise de vari?ncia, e regress?o, utilizando-se o teste t a 5% de signific?ncia. O RP destacou-se pelos elevados valores das fra??es de carboidratos n?o fibrosos e de prote?na de r?pida fermenta??o ruminal (A+B1), o que conferiu maior propor??o dessas fra??es nas dietas com a substitui??o de 100% do milho pelo o RP e maior sincronismo da disponibilidade de energia e prote?na no r?men. N?o houve efeito (P>0,05) dos n?veis de substitui??o sobre o consumo, digestibilidade dos nutrientes, balan?o de compostos nitrogenados e ganho de peso. Os diferentes n?veis de substitui??o n?o afetaram (P>0,05) o pH do l?quido ruminal e as concentra??es dos ?cidos graxos vol?teis, por?m para a concentra??o de nitrog?nio amoniacal (N-NH3) foi observada redu??o linear (P<0,05) em fun??o dos n?veis de substitui??o, em que cada 1% de RP promoveu redu??o de 0,11 mg/dL na concentra??o de N-NH3, o que pode estar relacionada ao aumento na disponibilidade de energia no r?men, que possibilita maior utiliza??o da am?nia para o crescimento microbiano. A adi??o de RP causou redu??o de at? 51,15% no custo da ra??o concentrada. Concluindo-se que o RP pode substituir totalmente o milho nas ra??es concentradas de ovinos.Made available in DSpace on 2016-04-28T14:59:41Z (GMT).
