ArticleItem Open Access Constraints in preparation of silage(2016-06) Deepa, K.; Senthilkumar, S.; Suganya, T.; Kalpana, K.; Purushothaman, M.R.; TANUVASSilage is a product formed when grass or other material of sufficiently high moisture content (e.g., forage legumes and forage corn) liable to spoilage by aerobic microorganisms is stored anaerobically. However, ensiling forages has its own set of disadvantages. There can be extensive losses in storage if the silage is mismanaged. This loss of nutrients and other problems can be overcome by sufficient guidelines which need to be followed during ensilage.ArticleItem Open Access Estimating Methane Emission Using SF6 Technique in Ruminants(2016-04) Deepa, K.; Senthilkumar, S.; Kalpana, K.; Senthilkumar, R.P.; Muralidharan, T.; Suganya, T.; Sasikumar, P.; Sureshkumar, R.; TANUVASSulphur hexafluoride (SF6) is the most common tracer gas used to estimate CH4 production from the ruminants. This technique relies on a constant release of SF6 from a bolus administered into the rumen of an animal. Gas samples are collected from around the nose and mouth of the animal via a harness and evacuated canister and these samples are then analysed using a gas chromatograph. The release rate of SF6 from the bolus and the ratio of SF6 to CH4 in the breath sample are used to calculate the CH4 emission from each animal. This method of estimating CH4 emissions has the advantage that individual grazing animals can be measured, as well as groups of animals simultaneously. It is also a relatively cheap method for measuring CH4 emissions, although the cost of purchasing a gas chromatograph capable of measuring SF6 in parts per trillion is considerable.ArticleItem Open Access Herbal Feed Additives in Poultry(2016-06) Suganya, T.; Senthilkumar, S.; Deepa, K.; Muralidharan, J.; Gomathi, G.; Gobiraju, S.; TANUVASUse of herbal feed additive is gaining importance in animal production due to ban on use of certain antibiotics, harmful residual effects and cost effectiveness. Probiotics, prebiotics, enzymes and highly available minerals as well as herbs can be seen as alternatives. Herbs, spices and their extracts (botanicals) have a wide range of activities. They can stimulate feed intake and endogenous secretions or have antimicrobial, coccidiostatic or anthelmintic activity. A major field of application of herbs is the protection of animals and their products against oxidation.ArticleItem Open Access Metal Toxicosis in Poultry – A Review(2016-04) Suganya, T.; Senthilkumar, S.; Deepa, K.; Muralidharan, J.; Sasikumar, P.; Muthusamy, N.; TANUVASAt high levels all mineral elements can produce adverse effects in animals. Thus, the essential minerals must be provided in the diet at concentrations sufficient optimum response and the dietary intake of other minerals must be low enough to provide complete safety for both the animals and also the human population which will consume the meat and eggs. Dietary maximum tolerable levels have been generated which can serve as guidelines in ensuring safety for both domestic animals and humans. Although there are several potential dietary sources of toxic elements for poultry, adequate quality control programs at the feed mill coupled with good manufacturing practices and a knowledgeable nutritionist should greatly decrease the likelihood of significant contamination. Contaminated ground water from hazardous waste sites and other forms of industrial pollution as well as municipal waste systems probably represent the most likely sources of contamination in the United States at the present time. (Henry and Miles., 2001).ArticleItem Open Access NIRS in Animal Sciences(2016-04) Deepa, K.; Senthilkumar, S.; Kalpana, K.; Suganya, T.; Sasikumar, P.; Thirumalaisamy, G.; Sureshkumar, R.; Vasanthakumar, P.; TANUVASThe standard chemical method of analysis of the most important quality parameters of raw materials and finished products takes a long time and cost when compared to production process. Therefore, the application of the NIRS method, as a rapid method, enables that the analysis of the content of important ingredients in feed production is completely in line with the production process. NIRS is, in fact, an empirical and secondary analytical technique that requires previous calibration by using samples of known composition and properties determined by certain standard (laboratory) methods of analysis. (Givens and Deaville, 1999). Today the NIRS technology is very compatible with the internet technology to transfer electronic data in both directions, thereby reducing the cost of NIRS data interpretation and report distribution.ArticleItem Unknown Supplementation of Molasses in Livestock Feed(2016-06) Senthilkumar, S.; Suganya, T.; Deepa, K.; Muralidharan, J.; Sasikala, K.; TANUVASMolasses is a sticky dark by-product of processing sugar cane or sugar beets into sugar. Molasses can be a source of quick energy and an excellent source of minerals for farm animals. Molasses can also be a key ingredient for cost effective management of feeds and pastures. The calcium content of sugar cane molasses is high (up to one percent), whereas the phosphorus content is low. Cane molasses is also high in sodium, potassium, magnesium and sulphur. Beet molasses is higher in potassium and sodium but lower in calcium. Molasses also contains significant quantities of trace minerals such as copper, zinc, iron and manganese. Supplementing poor quality hay with molasses will increase feed intake and improve palatability. Microbes in the rumen break down the sugars in molasses rapidly, which extensively causes a rapid release of energy that makes molasses very useful for balancing other feeds in the dairy diet all year round. Feeding molasses to farm animals will improve digestion of pastures/hay; increase milk production, help maintain body condition and appetite and result in less feed waste. Cane sugar, which has similar benefits to molasses, is an inexpensive alternative to use.ArticleItem Unknown Therapeutic Properties of Noni (Morinda citrifolia) and its Products(2016-06) Senthilkumar, S.; Deepa, K.; Suganya, T.; Janakarajan, M.; Muralidharan, J.; Vasanthakumar, P.; TANUVASNoni (Morinda citrifolia) is a drought tolerant tree, which grows in adverse climatic conditions (20-450 C).
