A 2 x 2 factorial experiment with pigs was undertaken to investigate the effect of particle size (fine and coarse) and feed processing (pelleted and nonpelleted) on morphological characteristics in the small intestine, cecum, and colon of pigs and on the adhesion of Salmonella enterica serovar Typhimurium DT12 to the ileum in vitro. Ninety-six pigs (average BW = 33 +/- 7 kg) were fed the experi...

Three experiments were conducted to determine the effects of pelleting and extrusion of feeds on the utilization of phytate P by broilers. The first experiment investigated the effects of pelleting the whole corn-soybean meal (SBM) diet, the corn, or SBM separately on phytate P utilization. The P-deficient basal diet contained 0.5% total P and 0.2% phytate P. Steam pelleting the whole diet, the...

A study was carried out to determine if the presence of bacitracin methylene disalicylate (BMD) interfered with the assay of chlortetracycline (CTC) and if the presence of CTC interfered with the assay of BMD when both are combined in a pig feed. In addition, the potential influence of steam pelleting on active concentrations of BMD and CTC was determined. Further, the stability of BMD in the p...

Aqueous and ethanolic extracts of duckweed (Lemna pauciscostata) meal was tested on fungal isolates from stored pelleted fish feeds to ascertain its efficacy as an antifungal agent against feed spoilage fungi. Test organisms used were Fusarium oxysporium, Penicillium digitatum, A. niger, A.flavus, A.fumigatus, Rhizopus oryzae and .stolonifer .Phytochemical analysis of the crude extract was also...

Seed vigor is an important trait for tobacco production. However, the evaluation of seed using molecular biomarkers scarcely reported in tobacco. In this study, development marker isopropylmalate synthase NtIPMS was conducted to detect ageing degree and priming effect Quantitative real-time PCR (qRT-PCR) analysis showed that expression significantly induced at initial imbibition stage during ge...

The present study compared the performance of commercial PCR-based Salmonella enterica detection methods (BAX System Q7, the iQ-Check Salmonella II kit, and the TaqMan Salmonella enterica detection kit) with culture-based methods (modified semisolid Rappaport-Vassiliadis [MSRV] and NMKL71) in spiked and naturally contaminated samples of feed mill scrapings (FMS), palm kernel meal (PKM), pellete...

This research was designed to examine the effect of both physical form of the roughage (chaff or ground/pelleted) and or urea supplementation on intake, and digestion by sheep fed barley straw housed at high ambient temperature (40C). The experimental design was factorial 2 x 2 x 4. Sixteen Merino sheep, weighing 26.3 ± 2.1 (SE) kg were randomized into four groups (n=4). Each group was fed one ...

an experiment was conducted to predict the true metabolizable energy (tmen) of compounded starter feeds of broiler chickens trough their chemical composition using precision-feeding method of sibbald in male boilers. in the first, eight compounded feed samples provided from eight feed plants and their chemical composition determined in laboratory. results of chemical composition showed that ave...

1. Measurements were made of portal blood flow, heat production and oxygen consumption in the digestive tract of sheep either fasted or given the following diets: chopped, dried grass, pelleted, dried grass; chopped, dried lucerne; pelleted, dried lucerne, or a pelleted barley diet. 2. For sheep that had been fasted for 48 h, portal blood flow was 1.84 l/min, total visceral heat production was ...

The aim of this experiment was to determine the productive performance and egg quality of Japanese quails fed different types of processed rations (mash, extruded, or pelleted). One hundred and fortyfour 18-w-old quails (Coturnix coturnix japonica) were housed in galvanized wire cages and fed a 21.50% CP and 2850 kcal ME/kg basal feed supplied in mash, extruded, or pelleted form. Experimental d...
