ABSTRACT
In situbags made from microfiber fabrics have a greater surface area and filtration efficiency that retains the fine particles and reduce the variation in the results. Also, it is more durable than that made from traditional fabrics. This work aimed to study the effect of filament denier on the performance of in situbags. Two polyester microfilaments with 0.4 and 0.7 deniers were used in manufacturing of four fabrics. Physical and mechanical properties of manufactured fabrics were measured before and after incubation to show the efficiency ofthe manufactured samples. In vitro trail was conducted to estimate ruminal degradability after 24 and 48 hours for three feedstuffs using three cannulated rams as replicates. The mechanical properties of manufactured in situbags were significantly affected with both denier per filament and weft densities. According to the statistical analysis of radar chart, sample 2 remarked the highest value which achieved the acceptable ruminal dry matter disappearance compared with Ankom bags in different incubation times.(AU)

Microfiber fabrics are more efficiency in retaining fine-particles that increase the variation in in situ degradability. The aim of this was to examine the performance of in situ bags made from different microfiber fabric for meeting the required specification and their ruminal degradability compared with standard Ankom in situ bags. Four fabrics were manufactured using polyester microfiber with 1.04 denier, weft yarn counts (150 and 300), weft density (22 and 28 picks / inch), plain 1/1 textile structure. Physical and mechanical properties of manufactured fabrics were measured before and after incubation. Ruminal degradability was measured for three feedstuffs (soybean meal, wheat bran and berseem hay) using three rumen-fistulated rams as a replicates after 24 and 48 hours. Fabric's pore size was significantly decreased as either yarn weft count or density increased. Yarn weft count had a significant effect on all fabric's properties. Air permeability was significantly decreased as fabric's weft yarn count increased. Sample (1) meet the specific requirements for in situ bags and showed the nearest degradability values to those observed using Ankom bags for all feedstuffs in most incubation times. Microfiberin situ bags could be used in in situ ruminal degradation trials to reduce the variation in results due to the present of the fine particles.(AU)
