Effects Of Cellulase Supplementation And Wheat Bran On Mineral Utilization In Broilers

In this experiment, 3-week-oId broiler type chicks were assigned to 24 groups of 10 chicks each for two replicates of 12 treatments. A completely randomized experiment with a 4 x 2 factorial arrangement involved feeding 0, 10 or 20% wheat bran or 20% wheat bran plus cellulase. The birds were housed in electrically heated batteries with raised wire floors. Feed and water were supplied ad libitum. The wheat bran was defatted and the cellulase (imported from Boerhinger, Mannheim, Gmn H. W. Germany) was mixed at .008% in the total diet. The enzyme supplementation to the diet was as a dry preparation

Some Effects Of Enzyme Supplementation And Various Wheat Bran Levels In A Broiler Diet On Apparent Digestibility

It is generally recognized that birds do not have an enzyme in their digestive fluid which digests cellulose. However, cellulosic materials are major renewable resources available in large quantities which need to be properly utilized to help meet our needs for energy, chemicals, food and feed for a long-range solution. A variety of lignocellulosic materials containing acid-detergent fibers, are available and microorganisms capable of degrading either one or more of the three main constituents, viz., cellulose, hemicelluose and lignin, have been studied. A further variety of strategies are being explored, including thermal methods of degradation such as pyrolysis or biological methods such as enzymatic hydrolysis and fermentation

Sampling of Large Round and Large Square Bales

Four hay probes were used to sample four lots of hay. The lots of hay were as follows: alfalfa large round bales, alfalfa large square bales, alfalfa-grass mix large round bales, and alfalfa-grass mix large square bales. Probes used were as follows: E-Z Probe, John Skogberg handcrafted probe, Utah Hay Sampler, and Frontier Mills probe. Six bales from each lot were sampled. Dry matter (DM), crude protein (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF) percentages and relative feed value (RFV) were predicted by near infrared reflectance spectroscopy. Bale variation within hay type was much greater than probe variation. Bale variation was significant for all measurements except DM. Probe type only affected NDF% and RFV
