Background： A novel extruded product was characterized with a metabolism and lactation trial to establish the product＇s energy content, and its effects on lactating sow performance. The product was composed of a 60：40 corn-soybean blend, which was then extruded. This product containing the co-extruded 60：40 corn-soybean blend was commercially developed and is used extensively in swine diets in southwest Minnesota. GE of dietary treatments were determined by isoperibol bomb calorimetry. Twelve barrows （59.9 ± 1.4 kg）, were used to determine the digestible and metabolizable energy of the extruded product. DE of treatments was determined by subtracting fecal energy from GE provided to barrows by each respective treatment. ME was determined by subtracting urinary energy from calculated digestible energy. Sixty-three sows were used for the lactation trial. Three dietary treatments were utilized： CONTROL （an industry standard diet）; PRODUCT （contained the product, vitamins and minerals）; OIL （matched the lysine：ME ratio of PRODUCT by addition of soy oil）. Sow weight, backfat thickness at the right and left last ribs, body condition score, number of piglets, and litter weights were recorded on the date of farrowing （d 0）, （d 9）, and at weaning. Blood and milk samples were obtained at weaning, and blood was analyzed for plasma urea nitrogen （PUN）, milk was analyzed for total protein and fat content. Results： On a dry-matter basis, the test diet provided 3,908 kcal/kg DE and 3,833 kcal/kg ME, which was significantly greater than the basal diet, which provided 3,633 kcal/kg DE and 3,567 kcal/kg ME （P 〈 0.0001）. These data were used to establish the DE and ME of the product, which were 3,882 kcal/kg and 3,798 kcal/kg, respectively, on an as-fed basis. No effect of diet was observed for changes in sow backfat （RBF P = 0.24; LBF P = 0.07） or body condition score （P = 0.12） during lactation. Milk total protein （P = 0.69）, fat （P = 0.66）, PUN, average piglet gain （P = 0.55） and pi

Background： The immense growth in global bioethanol production has greatly increased the supply of by-products such as whole stillage and condensed distiller＇s solubles, which could be potentially used for animal feeding. The objective of this study was to investigate effects of liquid feeding high levels of corn condensed distiller＇s solubles（CCDS） and whole stillage（CWS） on growth performance, carcass characteristics, belly firmness and meat sensory traits of ***： A total of 256 pigs were blocked by sex and initial BW（13.5 ± 2.5 kg）, and pens of pigs（8 pigs/pen） were randomly allocated to 1 of 4 dietary treatments（8 pens/treatment）： 1） corn-soybean meal based diet as control, 2） 25%CWS ＋ 5% CCDS, 3） 19.5% CWS ＋ 10.5% CCDS, and 4） 19.5, 26, and 32.5% CWS ＋ 10.5, 14, and 17.5% CCDS in phases 1（28 d）, 2（38 d）, and 3（60 d）, respectively. Inclusion levels of CCDS and CWS for Treatments 1, 2, and 3 were fixed during all the three phases of the experiment. Inclusion levels of CWS and CCDS were on 88% dry matter basis. The liquid feeding system delivered feed from the mixing tank to feed troughs by high-pressure air, had sensors inside feed troughs, and recorded daily feed intake on the basis of a reference feed intake curve. The pigs were fed 5 to 10 times per day with increasing frequency during the ***： Control pigs had greater（P 0.10） dressing percentage, loin muscle depth, and lean percentage were observed among the four treatments. Inclusion of CWS and CCDS reduced（P 0.10） the overall like,flavor, tenderness and juiciness of loin chops when compared with the control ***： In conclusion, our results indicate that including 30–50% of a mixture of whole stillage and condensed distiller＇s solubles in the growing-finishing diets may reduce growth performance, carcass weight and belly firmness, but does not affect pork sensory traits.

Dear Editor, Plant cells are encased by cell walls--rigid yet highly dynamic composite structures, which consist of cellulose, hemicelluloses, pectic polysaccharides, glycoproteins, and the polyphenol lignin （Somerville et al., 2004）. Biosynthesis of the wall polysaccharides is facilitated by donor- and acceptor- substrate-specific glycosyltransferases catalyzing the transfer of the sugar moiety from a nucleotide sugar to form a specific glycosidic linkage. Glycosyltransferases have been grouped into families based on primary structure, one of which is fam- ily GT77 （***/GT77_***）.

Current Research Status of Heterodera glycines Resistance and Its Implication on Soybean Breeding

引用

Engineering 2018年第4期4卷 534-541页

作者： Guiping Yan Richard baidoo Department of Plant Pathology North Dakota State University Fargo ND 58108 USA

Heterodera glycines （i.e., soybean cyst nematode, SCN） is the most damaging nematode pest affecting soybean crop worldwide. This nematode is managed by means of crop rotation with selected resistant sources. With increasing reports of virulent SCN populations that are able to break the resistance within commonly used sources, there is an increasing need to find new sources of resistance or to broaden the resistance background. This review summarizes recent findings about the genes controlling SCN resis- tance in soybean, and about how these genes interact to confer resistance against SCN in soybean. It also provides an update on molecular mapping and molecular markers that can be used for the mass selection and differentiation of different resistance lines and cultivars in order to expedite conventional breeding programs. In-depth knowledge of SCN parasitism proteins and soybean resistance responses to the pathogen is critical for the diversification of resistant sources through gene modification, gene stacking, or incorporation of novel sources of resistance through backcrossing or genetic engineering.

The cultivation of many crops in Africa is negatively affected by a number of constraints, the most important of which is the incidence of pests and diseases. In many areas of the world, the most preferred option in the management of pests is the application of synthetic chemical pesticides. Due to the negative effects of pesticides on humans and the environment as a whole, efforts are being made to find alternatives for pest management. Ethanolic extracts of the leaves and roots of Lantana camara were tested against the major pests of okra, Abelmoschus esculentus. The plant extracts were compared with a standard chemical insecticide, Mektin (a.i 18 g/L abamectin) in a randomly complete block design with four treatments and three replications. Parameters studied included the major pests of the plant and the damage caused, leaf area, plant height as well as yield of okra. Cotton aphids, Aphis gossypii, the tobacco whitefly Bemisia tabaci and the cotton flea beetle, Podagrica puncticollis were the major pests encountered on okra plants. Aphis gossypii and B. tabaci populations were significantly lower on the L. camara-sprayed plots compared with the control plots. Similarly, P. puncticollis numbers were significantly smaller on the L. camara-sprayed plots than the control plots. There were no significant differences between the treatments and the control for plant height, leaf area and yield. The significant reduction in pests numbers on the L. camara-sprayed plots indicates its potential as an alternative to chemical insecticides, thereby reducing the reliance on chemical insecticides in the management of insect pests.

Bambara groundnut, Vigna subterranea is an important legume crop that is adaptable to the dry regions of Africa. It is a major source of protein to people in many parts of Africa. One major constraint to increased production of the crop is the incidence of the storage pest Callosobruchus maculatus which causes significant weight loss to seeds in storage. The preference of the cowpea beetle C. maculatus for a particular seed coat colour was determined using four different colour types of bambara groundnut in an arena. The olfactory attractiveness of testa against cotyledon and cotyledon against whole grain was carried out in an olfactometer. Oviposition preference of C. maculatus on the different seed colours was determined. In the arena experiment significantly more of the beetles showed preference for cream and mottled seeds than red and black seeds. Significantly more beetles chose seeds with testa over decorticated seeds as well as whole grain over decorticated seeds. Colour significantly affected the seeds as oviposition sites. Significantly fewer eggs were laid on red and black seeds than cream seeds in both the choice and no choice tests (P k-coloured seeds which showed lower acceptability to C. maculatus as oviposition site.
