Effects of 2 pellet diameters for piglets pre- and postweaning on feed intake, BW, and feed-related behavior were studied in 3 experiments. In Exp. 1, 19 litters were provided with pellets of 2 and 12 mm in diameter in a choice-feeding setup from d 4 of lactation onward. From d 4 to 18, piglets preferred the 12-mm diameter pellet over the 2-mm diameter pellet (519 vs. 168 g/pen; P < 0.001). In ...

turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. in order to obtain desired surface quality by machining, prope...

The wear behavior of a single-layer electroplated cubic boron nitride (cBN) grinding wheel was investigated in creep feed Inconel 718 narrow-deep-groove with width 2 mm. In this paper, the protrusion height cBN grits on side edge measured by three-dimensional optical profiler, and scanning electron microscope used to detect topography worn grit nickel bonding layer. investigation results indica...

Nutrient absorption is important in all stages of life. As the diet of an animal changes from birth on, morphological and biochemical adaptation can be anticipated in order to accommodate changing demands. The main focus of the present study was to examine the relationship between age and diet on the potential for peptide transport via PepT1 in the gastrointestinal tract of lambs and to relate ...

Samples of rumen digesta were collected from 2 cows fed with a 100:0 or 40:60 forage/concentrate diet 1 h before and 2 h after feeding. Enzymes from particle-associated microorganisms were extracted by 5 different methods, including physical (freezing, grinding and sonication) or chemical and enzymatic (autolysis in a buffer, lysozyme and CCl4) treatments. Hydrolytic enzyme activities were meas...

One hundred and sixty seven Droughtmaster cows with calves were used in two experiments to evaluate the effect of early weaning and creep feeding on cow reproduction rates. Weaning of calves that weighed 48-92 kg instead of the conventional weaning weight of about 180 kg improved cow live weights and increased pregnancy rates by 48% at weaning. The early weaned calves were raised on Stylosanthe...

Two experiments evaluated digestive and performance effects of field pea-based creep feed in nursing calf diets. In Exp.1, eight nursing steer calves (145 +/- 27 kg initial BW) with ruminal cannulas were used to evaluate effects of supplementation and advancing season on dietary composition, intake, digestion, and ruminal fermentation characteristics. Treatments were unsupplemented control (CON...

This study investigated the influence of particle size and feed form on the performance, the AME(n), and the gross morphological and histological parameters of various segments of the digestive tracts of broilers fed wheat-based diets. The experimental design was a 2 x 2 factorial arrangement of treatments evaluating 2 wheat particle sizes (medium and coarse) and 2 feed forms (mash and pellet)....

1Carrington Research Extension Center, NDSU 2Hettinger Research Extension Center, NDSU The objective of this project was to evaluate corn processed by fi ne grinding or rolling or fed whole in relation to dietary forage level for fi nishing yearling steers. Results indicate when forage levels are greater than 15.5 percent on a dry-matter basis, dry rolling or fi nely grinding corn to maintain a...
