White backed planthopper (WBPH; Sogota furcifera Horvath) has become the major threat to rice crops throughout Asia, damaging plants both through its feeding behavior and by acting as a virus vector. Here, we developed a novel method for biologically controlling WBPH by using endophytic bacterium to express anti-pest plant lectins. Strain SJ-10 of an endophytic bacterium, characterized as Enter...

Three experiments were conducted to evaluate effects of rice and other cereal grains on growth performance and health of weanling pigs. Pigs (1,008 in Exp. 1 and 3 and 1,004 in Exp. 2; 21 d old) with an initial BW of 5.8 ± 1.0 kg were used. Pigs in each experiment were divided into 3 BW blocks (heavy, medium, or light) in each of 4 rooms, resulting in 12 blocks per experiment. Each pen within a...

Rats fed diets with cadmium (Cd) concentrations similar to that found in human diets, and nutritionally marginal with respect to iron (Fe), zinc (Zn), and calcium (Ca) retained 10 times more Cd in the duodenum than rats fed adequate mineral diets. In the current study, 2 experiments were performed to determine the role of intestinal metallothionein (MT) in the accumulation of duodenal Cd, and t...

Experiments were carried out to study the digestibility of a cassava (gari) diet and its effect on growth in young male dogs. Three groups of dogs were fed on diets with rice (control), cassava (gari), and rice + cyanide respectively as the carbohydrate source. Each diet contained 130 g crude protein (nitrogen x 6,25)/kg, was supplemented with vitamins and minerals, and was fed for 14 weeks. Va...

The aim of this study was to determine the effect of different physical forms and urea treatment of rice straw on feed intake, rumen fermentation, and milk production. Four, multiparous Holstein crossbred dairy cows in mid-lactation with initial body weight (BW) of 409±20 kg were randomly assigned according to a 4×4 Latin square design to receive four dietary treatments. The dietary treatments ...

One major concern regarding the release of Bt rice is its potential impact through tritrophic interactions on nontarget arthropods, especially natural enemies. We studied the effects of two Bt transgenic rice varieties, TT9- 3 and KMD1, expressing Cry1Ab/Cry1Ac and Cry1Ab, respectively, on a predatory ground spider [Ummeliata insecticeps (Bösenberg et Strand)] supplied with Bt rice-fed brown p...

Rice stripe disease, caused by Rice stripe virus (RSV), is one of the most serious rice diseases in temperate and subtropical regions of the world. Since RSV is not transmissible mechanically, an insect transmission test was the original basis for identification of the viral population and cultivar resistance. A simple, rapid and reliable method is described by which virus-free small brown plan...

The aim of this study was to investigate the effects of isolated protein from white rice on lipid metabolism in a hypercholesterolemic animal model. Male Sprague-Dawley rats were divided into three groups and fed either a normal diet or a high-cholesterol diet (HCD) containing either casein or isolated rice protein for 4 weeks. Compared with rats fed a HCD with casein, the total cholesterol (TC...

Forty-eight, 21-d-old pigs were used to examine the effects of different types of cooked white rice on starch digestion, digesta and fermentation characteristics, shedding of beta-haemolytic Escherichia coli and performance after weaning. Pigs received one of three rice-based diets: (i) medium-grain Amaroo (AM), (ii) long-grain Doongara (DOON), and (iii) waxy (WAXY). The remainder of the diet c...
