Study of Dietary Protein Levels on Growth and Survival of Carp Spawn
ISBN: 9783843355247 / Angielski / Miękka / 60 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Proteins are the most important and essential food components.The growth of the fish depends upon the quality of proteins in the diet. The scientific fish culture in India aims at a high rate of the survival and production of spawn, fry, fingerlings and table sized fish. The aim is achieved by fertilization of the ponds and by providing supplementary feeding to the fish stocks. But, in intensive fish culture systems where the density of spawn, fry and fingerlings per unit water area is kept very high the proteins and certain other nutrients become growth limiting factors. Present study...

Nematodes of Banana
ISBN: 9783843357463 / Angielski / Miękka / 316 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Banana is one of the major fruit crops of tropics and sub-tropics forming an important item in diet of millions across the globe. India is the second largest banana producing country of the world with the production of 3633 thousand tons per annum. Nematodes constitute one of the major limiting factors in banana production. Tylenchids, the plant parasitic nematodes have been recognised as a major constraint in banana production and are responsible for serious yield losses. The dorylaimid nematodes act as vectors of so many fungal, bacterial and viral diseases of this important fruit crop....

Live Food: Mass Production, Biochemical Profiling and Enrichment
ISBN: 9783843363495 / Angielski / Miękka / 188 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Aquaculture is the fastest growing food production sector in the world. The most critical stage in the production cycle for many species is still the larval stage. The primary problem in larviculture is food. Early stages of fish have very high potential of growth, which require an abundant and adequate supply of nutrients. Live food plays important role to meet the nutritional requirements of many fish species. As interest in larviculture is increasing, demand for live food is also increasing. To meet the requirements, research on the development of mass production techniques for live feed...

Genetically improved parasitoid strain for biological pests control
ISBN: 9783843368315 / Angielski / Miękka / 100 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A strain of egg parasitoid, Trichogramma chilonis was developed for tolerance to insecticides and high temperature. The LC50 values were 13-folds higher for endosulfan, 233-folds for monocrotophos and 4- folds for fenvalerate. In high temperature, the developed strain could parasitise up to 53.3 eggs as compared to 6.7% by susceptible strain. Exact identification of developed strain was done using primers, viz., OPA-4,OPC-12 and OPL-4. Increased GST activity was recorded in developed strain, whereas decrease in carboxylestrase and similar acetylcholine activity to susceptible...

Fiber Degrading Enzyme in Poultry Feeds
ISBN: 9783843372053 / Angielski / Miękka / 76 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Poultry feed contains about 5-6% crude fiber but fiber degrading enzymes are absent in broilers. To utilize this portion of feed different fiber degrading enzymes are supplemented in poultry diets that enhance the growth performance and digestibility of nutrients. Total nine isoproteinous experimental diets were formulated with three enzyme levels (0, 500 and 1000 g/ton of feed) and three energy levels (ME: 2700, 2800 and 2900 kcal/kg of diet). The results suggested that enzyme (Rovabio TM Excel) supplementation at 1000g/ton of feed significantly improved body weight gain and feed conversion...

Technique in Metabolizable Energy Assays for Poultry
ISBN: 9783843362047 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Most developing countries are facing difficulties in providing sufficient animal protein for their population. The cost of feed is very high and this has made livestock production very expensive. Since energy is one of the most expensive segments of a poultry ration, accurate knowledge of the available energy content of feedstuffs is necessary to formulate the most economical least-cost rations. This research work determines (i) the true metabolizable energy (TME) of maize pap waste (MPW) and rice milling waste (RMW), (ii) the growth response of broiler birds to diets containing graded levels...

Amphibians watched the dinosaurs come and go, but today almost half of them are threatened with extinction. Amphibian species diversity is highest in the tropics. Hibernation is usually thought of as a resting condition in which an animal exists in a state of complete or partial torpidity. This is associated with low temperature. During this time animal's dramatically slowing heart and breathing rates, lowering body temperature, going for long periods without eating. Biochemical and physiological parameters played very crucial role during hibernation. Antioxidant activity, enzyme expression...

Infanticide in Monkeys
ISBN: 9783838343150 / Angielski / Miękka / 152 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Infanticide or the killing of dependent offspring by a mature animal of its own kind occurs in various species of monkeys. The interpretation on the adaptive significance of infanticide in monkeys has been one of the most controversial topics in animal behavior. Documenting infanticide in non-human primate species in the wild is not an easy task since it often occurs quickly and field observers could easily miss out the actual process. The author, who is an international primatologist with 25 years of experience in watching wild monkeys in all three tropical continents, has managed...

From the present results and previous studies, itcould be concluded that the neurotoxicity whichcaused by different cement components may be, inpart, due to the elevation in glutamate which lead toincrease the intracellular of calcium concentrationand the inhibition of membrane-bound Na+, K+, Ca2+ATPase activity which lead to cellular alterationsand death. So long term exposure to cement componentsas environmental pollutants may lead toneurodegenerative diseases.
