The effect of cecectomy on food intake and defecation was studied in Wistar rats fed ad libitum or under restriction. Food intake, fecal output, dry matter and water content of feces, and numbers of scybala increased significantly in both groups of cecectomized rats. The weight of scybala and their dry matter and water content also increased after cecectomy. Water intake did not change signific...

Two lamb trials were conducted to determine the effects of particle length (PL; 2.5 vs 10 cm) and sodium hydroxide (NaOH) treatment (0 vs 4%) of wheat straw on dry matter (DM) intake and site and extent of DM and neutral detergent fiber (NDF) digestion. Lambs in the first trial were fed ad libitum once daily. Lambs in the second trail were fed four t imes/d at 6-h intervals and were sacrificed ...

Supplementation of dairy rations with steroidal sapogenins was evaluated in an in vitro, an in situ, and a production trial. Sixteen in vitro semicontinuous rumen cultures were supplied a 55:45 concentrate to roughage substrate with Sarsaponin concentrations of 0, 33, 55, and 77 ppm of air-dry feed for 22 d. Supplementation decreased protozoa numbers and increased bacterial numbers and acid det...

This study was conducted to investigate the effect of biological treatment withPleurotus floridafungi on chemical composition and rumen dry matter (DM) and organic matter (OM) degradability of wheat and barley straw. Wheat and barley straw were collected from Golestan province of Iran and after pasteurization mixed with fungi spawn (than 5% by weight). After 21 days samples were dried in oven (...

The temperature-phased anaerobic digestion (TPAD) process was used for the anaerobic digestion of the source separated biodegradable organic fraction of municipal solid waste (OFMSW). The TPAD process was used to co-digest OFMSW with primary wastewater solids (PS) at ratios of 20:80, 40:60, 60:40, and 80:20 O FM SW :PS. Th e OF MS W/P S feed mixtu re wa s slurrie d at co ncen trations up to 5.2...

(109)Cd-based K-shell X-ray fluorescence spectrometry (hereafter, for brevity, XRF) is used, often in epidemiological studies, to perform non-invasive, in vivo measurements of lead in bone. We conducted the first interlaboratory study of XRF via the circulation of nine goat tibiæ in which the mean lead value ranged from 4.0 µg g(-1) to 55.3 µg g(-1) bone mineral. The test tibiæ were subsequentl...

Correlations between kernel vitreousness and ruminal in situ (RDMD) and total tract dry matter (TDMD; sum of ruminal in situ and post-ruminal in vitro measurements) degradabilities were determined for 33 diverse corn germplasm sources. These included a wide range of endosperm characteristics from opaque 2 (o2) types to densely packed flint types, and a number of intermediates. Harvests were don...
