Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Historically, ruminant animals have provided farmers with the ability to utilize marginal lands for the production of high quality food for human consumption. Ruminants are able to derive their nourishment from feeds that are not in themselves capable of meeting the nutritional needs of the animal. They do this by supporting in the rumen, which is a greatly enlarged region of the stomach which precedes the animals digestive system, a microbial fermentation system. This system partially degrades complex polysaccharides and provides to the animal not only the degradation products (chiefly volatile fatty acids), but also secondary microbial metabolites and microbial biomass (most importantly microbial protein, which can be synthetized from inorganic nitrogen sources). A ruminant animal is able to survive, if not thrive, on a diet containing only cellulose, a non-protein nitrogen source such as urea, and trace minerals. The capacity of the rumen to process low quality feeds is limited by factors such as rumen volume, the time required for digestion of these feeds in the rumen, and the ability of the animal to chew the feed. Hodern ruminant animals have been intensively selected for high production potential, but the limited capacity of the rumen fermentation means that this potential cannot be realized by feeding the animal low quality feeds. The high production potential of these animals can only be realized by feeding large amounts of readily digestible, high quality feeds such as oilseed meals and grains.…

Vietnamese species from the family Plectopylidae are revised based on the type specimens of all known taxa, more than 600 historical non-type museum lots, and almost 200 newly-collected samples. Altogether more than 7000 specimens were investigated. The revision has revealed that species diversity of the Vietnamese Plectopylidae was previously overestimated. Overall, thirteen species names (anterides Gude, 1909, bavayi Gude, 1901, congesta Gude, 1898, fallax Gude, 1909, gouldingi Gude, 1909, hirsuta Möllendorff, 1901, jovia Mabille, 1887, moellendorffi Gude, 1901, persimilis Gude, 1901, pilsbryana Gude, 1901, soror Gude, 1908, tenuis Gude, 1901, verecunda Gude, 1909) were synonymised with other species. In addition to these, Gudeodiscus hemmeni sp. n. and Gudeodiscus messageri raheemi ssp. n. are described from north-western Vietnam. Sixteen species and two subspecies are recognized from Vietnam. The reproductive anatomy of eight taxa is described. Based on anatomical information, Halongella gen. n. is erected to include Plectopylis schlumbergeri and Plectopylis fruhstorferi. Additionally, the genus Gudeodiscus is subdivided into two subgenera (Gudeodiscus and Veludiscus subgen. n.) on the basis of the morphology of the reproductive anatomy and the radula. The Chinese Gudeodiscus phlyarius werneri Páll-Gergely, 2013 is moved to synonymy of Gudeodiscus phlyarius. A spermatophore was found in the organ situated next to the gametolytic sac in one specimen. This suggests that this organ in the Plectopylidae is a diverticulum. Statistically significant evidence is presented for the presence of calcareous hook-like granules inside the penis being associated with the absence of embryos in the uterus in four genera. This suggests that these probably play a role in mating periods before disappearing when embryos develop. Sicradiscus mansuyi is reported from China for the first time. 118 pp., 45 figs, gr. 8.…
