Book Description
The book contains proceedings of the XV International Scientific Conference INTERAGROMASH 2022, Rostov-on-Don, Russia. The agro-industrial complex is the most extensive and vital industry. It is rapidly developing by introducing the latest technologies and automating various processes necessary for the functioning of this area. The book is dedicated to engineering technologies of precision farming and agricultural robotics. It includes studies on natural resources variability, sustainable soil management, Agro Big Data, Internet of Things, software and mobile apps for precision agriculture, smart weather for precision agriculture, simulations models and decision support systems, expert systems, DGPS, soil physical and chemical characteristic sensors, machinery, etc. Different types of agricultural robots are presented in the book: autonomous fruit picking robots, farming bots that can seed and water plants, test the soil and remove weeds, completely autonomous robot for ecological and economical ultra-high precision spraying and weeding, harvesting robots with the special vision systems that can “see” fruits and understand whether they're ripe and ready to pick, and others. Also, the book covers advances in agricultural biotechnology in such areas of research as crop production improvement practices, genetic modification, as well as microbial biotechnology in agriculture, etc. The book is aimed for scientists, researchers, and graduate students. It is also useful for representatives of regional authorities, as it gives an idea of existing high-tech solutions for agriculture. The book is written and edited by international researchers, academics, and experts in the corresponding research areas.

Seminar paper from the year 2017 in the subject Veterinary medicine, Jimma University College of Agriculture and Veterinary Medicine, language: English, abstract: Objective of this review is focus on effect of feeding protected fat and protected protein on milk yield and its composition and how these nutrients are protected. Many researchers in this review investigate that the responses are highly dependent on the type of fat and protein supplement and the stage of lactation. A higher milk response was observed with saturated than with unsaturated fat supplements. Diet with added fat increase milk production compared with a control diet without added fat in cows. Feeding of bypass fat resulted in significant increase in milk yield and Fat Corrected Milk yield particularly in early lactation. The source of Protected fat are (origin (animal, plant, processed or whole oilseeds, calcium salts) and Cereal Grains such as corn, wheat, Barly, oil seeds, sun flower, cotton seed, soybeans and canola). The supplementation of protected protein in the diets of lactating animals increases the milk yield due to proportionate increase in the supply of amino acids to the host postruminally Milk yield in cows fed protected methionine for the whole experimental period was numerically higher than in cows of the other groups. However, the difference was not statistically significant .At the centeral high land of Ethiopia the Treatment of shredded wheat and barley straw with urea, molasses, salt and water prior to feeding is a technology that should be considered . Cows with excessive body tissue mobilisation at this stage may take up to 20 weeks to regain a positive energy balance status. Key words milk yield, composition ,protected fat , protein protected

Book Description
Due to the incorporation of niacin into the coenzymes NAD and NADP, niacin is of great importance for the metabolism of man and animals. Apart from niacin in feed and endogenous formation, microbial niacin synthesis in the rumen is an important source for dairy cows. But the amount synthesized seems to differ greatly, which might be influenced by the ration fed. Many studies revealed a positive impact of a niacin supplementation on rumen protozoa, but microbial protein synthesis or volatile fatty acid production in the rumen showed inconsistent reactions to supplemental niacin. The amount of niacin reaching the duodenum is usually higher when niacin is fed. But not the whole quantity supplemented reaches the duodenum, indicating degradation or absorption before the duodenal cannula. Furthermore, supplementation of niacin did not always lead to a higher niacin concentration in blood. Effects on other blood parameters have been inconsistent, but might be more obvious when cows are in a tense metabolic situation, for example, ketosis or if high amounts are infused post-ruminally, since ruminal degradation appears to be substantial. The same is valid for milk parameters. In the few studies where blood niacin and milk parameters have been investigated, enhanced niacin concentrations in blood did not necessarily affect milk production or composition. These results are discussed in the present review, gaps of knowledge of niacin’s mode of action on the metabolism of dairy cows are identified and directions for future research are suggested.
