Selected hydrolytic enzymes are added to animal feeds in order to degrade specific antinutritional factors and(or) to increase availability of certain components of feedstuffs to the animal. A method is described that allows detection and quantification of beta-glucanase activity in complex feedstuffs. The method is based on radial diffusion of an enzyme-containing feed extract through an agar ...

Arsenic exposures contribute significantly to the burden of preventable disease worldwide, specifically related to increased risks of cancer, diabetes, and cardiovascular disease. Most exposures are associated with natural contamination of groundwater, which is difficult to mitigate when these sources are used for drinking water. An anthropogenic source of arsenic exposure stems from the widesp...

One of the obstacles in raising tapah fish is supply feed. Tapah a carnivorous predatory that eats small so it very dependent on live For this reason, necessary to get used feeding with artificial feed (pellets). Usually for one time process making uses total weight 10 kg raw materials and takes approximately 4 hours. This situation detrimental farmers because they cannot increase number ponds ...

The altitudinal range of the aridland herbaceous perennial Cryptantha flava overlaps with the wintering range of mule deer (Odocoileous hemionus ) in the Colorado Plateau region of the western United States. Deer do not feed on C. flava , but do influence its microhabitat via excretion of nitrogenous compounds. We were interested in determining the importance of Mule deer in redistributing N ac...

When producing aquaculture fish feed pellets, the size of the output product is of immense importance. As the production method cannot produce pellets of constant and uniform size using constant machine settings, there is a demand for size control. Fish fed with feed pellets of improper size are prone to not grow as expected, which is undesirable to the aquaculture industry. In this paper an im...

Two key feed processing parameters, conditioning temperature and time, were altered to determine their effects on concentration of gelatinized starch and vitamin retention in a pelleted finishing swine diet. Diet formulation (corn–soybean meal based with 30% distillers dried grains with solubles) was held constant. Treatments were arranged in a 2 × 3 factorial design plus a control with 2 condi...

Hexazinone [3-cyclohexyl-6-(dimethylamino)-l-methyl-l,Z,5-tria~in~2,4,(lH,ZH)-dione] was tested in the 2, 1, and 0.5 cc size uellet (10% ai) against very small stems [average height, 1.97m; average ground line diameter (GLD), 2 cm] of water oak, Quercus nigra L., at 1.12 and 2.24 kg/ha on a sandy loam soil. First year defoliation of water oak by the 0.5 cc pellet at 2.24 kg/ha was significantly...

We tested the hypothesis that endometriosis can be induced in baboons more successfully by intra-pelvic injection of the pellet of menstrual endometrium when compared to its supernatant. Menstrual endometrium, separated into pellet (n = 5) and supernatant fractions ( n = 8), or phosphate buffered saline (1 ml, n = 7, controls) was injected laparoscopically into the pelvis. During laparoscopy 25...
