Intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate Anais da ABC (AABC)
SILVA,LEANDRO D. DA; PEREIRA,OODILON G.; SILVA,THIAGO C. DA; VALADARES FILHO,SEBASTIÃO C.; RIBEIRO,KARINA G.; SANTOS,STEFANIE A..
Abstract Legume silage can increase the forage quality of the diets as well as supply it with nitrogen, calcium and phosphorus. The objective was to evaluate the intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate. Twelve crossbred sheep with an average initial body weight of 32.2 ± 1.26 kg, with six animals cannulated in the rumen were distributed into four 3 × 3 Latin squares. The treatments were 1) Stylosanthes silage without concentrate (StS), 2) Stylosanthes silage with concentrate (StS+C), and 3) corn silage with concentrate (CS+C). StS diet showed lowest intake, except for neutral detergent fiber (NDF). The diets StS+C and CS+C showed similar intake of dry...

Evaluation of methods for the quantification of ether extract contents in forage and cattle feces Anais da ABC (AABC)
BARBOSA,MARCÍLIA M.; DETMANN,EDENIO; VALADARES FILHO,SEBASTIÃO C.; DETMANN,KELLY S.C.; FRANCO,MARCIA O.; BATISTA,ERICK D.; ROCHA,GABRIEL C..
ABSTRACT The objective of this study was to compare the estimates of ether extract (EE) contents obtained by the Randall method and by the high-temperature method of the American Oil Chemist's Society (AOCS; Am 5-04) in forages (n = 20) and cattle feces (n = 15). The EE contents were quantified by using the Randall extraction or AOCS method and XT4 filter bags or cartridges made of qualitative filter paper (80 g/m²) as containers for the samples. It was also evaluated the loss of particles, and concentration of residual chlorophyll after extraction and the recovery of protein and minerals in the material subjected to extraction. Significant interaction was observed between extraction method and material for EE contents. The EE estimates using the AOCS...
