For various experimental applications, microbial cultures at defined, constant densities are highly advantageous over simple batch cultures. Due to high costs, however, devices for continuous culture at freely defined densities still experience limited use. We have developed a small-scale turbidostat for research purposes, which is manufactured from inexpensive components and 3D printed parts. ...

Two experiments were conducted to determine the effects of pelleting, diet type (fat and fiber level), and withdrawal of dietary fiber and fat before marketing on growth performance, carcass yield, and carcass fat iodine value (IV) of finishing pigs. Each experiment used 288 pigs (initially 49.6 and 48.5 kg BW, respectively) with 6 dietary treatments arranged as 2 × 3 factorials. In Exp. 1, mai...

In this study, the effects of strain Beauveria bassiana (LPSC 1067) as an endophyte in corn plants on consumption, fecundity, and food preference of Dichroplus maculipennis were examined. We observed that the daily consumption by grasshoppers fed with control plants was almost twice that of those that were fed treated plants. Significant differences in fecundity of grasshoppers that were fed wi...

Sodium saccharin (NaSac) fed as 5% of Prolab diet promotes bladder tumor carcinogenesis in male I 144 rats initiated with ;V-|4-(5-nitro-2furyl)-2-thiazolyl|formamide (FANFT) fed as 0.2% of the diet for 4 weeks. NaSac also increases urothelial proliferation if fed for short periods in Prolab diet, but no increased proliferation is seen if it is fed for up to 10 weeks in AIN-76A semisynthetic di...

Sodium saccharin (NaSac) fed as 5% of Prolab diet promotes bladder tumor carcinogenesis in male F344 rats initiated with N-[4-(5-nitro-2-furyl)-2-thiazolyl]formamide (FANFT) fed as 0.2% of the diet for 4 weeks. NaSac also increases urothelial proliferation if fed for short periods in Prolab diet, but no increased proliferation is seen if it is fed for up to 10 weeks in AIN-76A semisynthetic die...

A study was conducted to determine the effects of corn distillers’ dried grain (CDDG) on the performance and egg quality of laying hens. The hens were fed dietary inclusions of CDDG at 0, 10, 20, 30 and 40% for a period of eight weeks. Average feed intake, weight gain, feed conversion ratio and nitrogen economy varied significantly (P<0.05) among dietary treatments. Birds fed 30% dietary CDDG h...
