This article describes genesis and the advances of schooling, research and extension of animal nutrition science and practices in Bangladesh. It portrays sine qua non of the advancement of animal nutrition, fodder production and frontier knowledge of allied disciplines. Domestic growth of good practices and its global and regional competitive advantages are delineated for supporting the growing need of safe animal sourced food pillared with profit, people, planet and the ethics of sustainable production of farm animals. A vision of becoming world middle income country with a national population plateau of around 202.0 million and demographic shifts by 2050 may require the annual production of 130.0 and 27.0 thousand tons of manufactured dairy and beef feed furthering global trading competitions for feed ingredients. This competition may be minimized through the production and supply of domestic sourced unique quality feeds and value additions to roughages. Capacity enhancement in research, education and extension will boost socioeconomic and the production efficiency of farm animals and enhance sustainable growth of feed industry racing with regional and global competitions.

In Vitro Treatment

This study was aimed to evaluate the in vitro Centrosema pubescens response treated with sulfur water and sheep manure. The experiment was conducted at Agrostology Laboratory, Department of Animal Nutrition Science, Faculty of Animal Husbandry, Sam Ratulangi University Manado. Randomized group design of 2 x 5 factorial patterns with three repetitions based on the rumen liquid collecting time was used in this research. There were two factors in this experiment; sheep manure and sulfur water. The first factors consisted of 0 ton/ha manure (A1) and 25 ton/ha manure (A2). The second factor was sulfur water that divided into 5 levels; 0% (B1), 25% (B2), 50% (B3), 75% (B4) and 100% (B5). Variables measured in this research were dry matter digestibility (DMD), organic matter digestibility (OMD), ammonia (NH3) and Volatile Fatty Acid (VFA). In vitro nutritional evaluation performed with all variables showed both factors (sulfur water and sheep manure) had significant differences (p < 0.001) and had no significant effect (p < 0.05) on each variable. Interaction of both factors was very significant (p < 0.01) ontotal VFA and DMD. From this study it can be concluded that production of NH3, VFA, total DMD and OMD showed an optimal result if treated with 25 ton/ha of sheep manure and 50% sulfur water (39.25 ppm).

Application Prospects

Natural astaxanthin helps reduce the negative effects caused by oxidative stress and other related factors, thereby minimizing oxidative damage. Therefore, it has considerable potential and broad application prospects in human health and animal nutrition. Haematococcus pluvialis is considered to be the most promising cell factory for the production of natural astaxanthin. Previous studies have confirmed that nonmotile cells of H. pluvialis are more tolerant to high intensity of light than motile cells. Cultivating nonmotile cells as the dominant cell type in the red stage can significantly increase the overall astaxanthin productivity. However, we know very little about how to induce nonmotile cell formation. In this work, we first investigated the effect of phosphorus deficiency on the formation of nonmotile cells of H. pluvialis, and then investigated the effect of NaCl on the formation of nonmotile cells under the conditions of phosphorus deficiency. The results showed that, after three days of treatment with 0.1% NaCl under phosphorus deficiency, more than 80% of motile cells had been transformed into nonmotile cells. The work provides the most efficient method for the cultivation of H. pluvialis nonmotile cells so far, and it significantly improves the production of H. pluvialis astaxanthin.
