Effects of including scrapes of residual dehydrated cassava in sheep feeding on intake and nutrient digestibility / Raspa de mandioca residual desidratada na alimentação de ovinos sobre o consumo e digestibilidade dos nutrientes

ABSTRACT

The objective of the present study was to evaluate the inclusion of 0%, 10%, 20%, and 30% of scrapes residual dehydrated cassava (SRDC) in sheep feed on the intake and total digestibility coefficient (DC) of nutrients. We used four sheep with body weight (BW) of 26.0 kg, distributed in a Latin square design. The sheep were placed in metabolism cages and received two meals a day. The variables studied were subjected to analysis of variance and differences were tested using regression analysis at the 5% significance level. We determined that the inclusion of different concentrations of SRDC in sheep feeding did not modify (p > 0.05) the intake of intake of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), or total carbohydrates (TC) expressed in g animal-1 day-1, g kg0.75-1 and %BW). On average 2.83%, 2.58%, 0.34%, 0.07%, 1.62%, 0.91%, and 2.24% of the BW were obtained for intake of DM, OM, CP, EE, NDF, ADF, and TC, respectively. However, the four experimental diets negatively affected the NFC intake and %BW (p 0.05). Different concentrations (0%, 10%, 20%, and 30%) of SRDC in sheep diets did not influence (p > 0.05) the digestibility coefficient...

RESUMO

Objetivou-se avaliar a inclusão de 0%; 10%; 20% e 30% de raspa de mandioca residual desidratada (RMRD) na alimentação de ovinos sobre o consumo e o coeficiente de digestibilidade total (CD) dos nutrientes. Foram utilizados quatro ovinos com peso corporal (PC) médio de 26,0 kg, distribuídos em delineamento em quadrado latino. Os ovinos foram alocados em gaiolas de metabolismos e receberam duas refeições por dia. As variáveis estudadas foram submetidas à análise de variância e as diferenças observa as foram testadas utilização equação de regressão a 5% de significância. A inclusão dos diferentes níveis de RMRD na alimentação de ovinos não alterou (p>0,05) o consumo de matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), extrato etéreo (EE), fibra em detergente neutro (FDN) e ácido (FDA) e carboidratos totais (CHT) expressos em g animal-1 dia-1, g kg0,75-1 e %PC. Os valores médios de 2,83%; 2,58%; 0,34%; 0,07%; 1,62%; 0,91% e 2,24% do PC foram obtidos para o consumo de MS; MO; PB; EE; FDN; FDA e CHT, respectivamente. Porém, os níveis de 0%, 10%; 20% e 30% de inclusão de RMRD influenciaram de maneira linear decrescente (p 0,05) o consumo...
