Authors: Samar Chandra Roy, Samar Chandra Roy
Abstract: The study was conducted to calculate the chromium contains in skin shavings of tannery industry and removal of it so that it can be used as feed. First initial chromium concentration was determined from untreated skin shavings sample. Then two studies were conducted for reducing chromium concentration from skin shavings. In case of first study 20 gm skin shavings and 10 gm Saccharomyces cerevisiae ware used in 500 ml water. The pH was measured 4.15 and it was kept in normal room temperature around 28OC for 48 hours. In case of another study some duckweed was used with15gm skin shavings in 3 litters water and kept for 48 hours in a plastic container in room temperature. When yeast cell grows it uptakes chromium ions from the solution and Duckweed has biosorption behavior for removal of several heavy metals including chromium from water solution. Then chromium concentration ware determined from the two samples treated with Saccharomyces cerevisiae and duckweed .Finally the percentage of chromium removed by two sample ware found 96.60% and 96.62% that ensure the above two process can be used for chromium removal from skin shavings.2014-01-01T00:00:00ZSTUDY ON WATER HYACINTH AS A CATTLE FEEDFarukhttp://dspace.cvasu.ac.bd/jspui/handle/123456789/26842024-01-15T05:59:13Z2014-01-01T00:00:00ZTitle: STUDY ON WATER HYACINTH AS A CATTLE FEED
Authors: Faruk
Abstract: It is believed that the origin of Water hyacinth to be Amazonia, Brazil, with natural spread throughout Brazil and to other Central and South American countries. Water hyacinth is available also in Asian countries like India, Bangladesh, China etc. To evaluate the nutritional value of water hyacinth, two step of trial was conducted at Feni district under a project work of Chittagong Veterinary and Animal Sciences University. The proximate composition of water hyacinth and its digestion was completed at animal nutrition laboratory during a period of six months. The DM, CP, CF, EE and total ash content of water hyacinth was 12.37, 11.06, 22.00, 1.01, and 12.82 per cent, respectively which was comparable to other perennial grasses available in Bangladesh. The digestion of water hyacinth was also observed though laboratory analysis and the per cent of digestibility of the collected sample was found as 19.16, 45.62, 18.63, 35.29, and 42.27 percent for DM, CP, CF, EE and total ash content, respectively. From this task, it may be concluded that water hyacinth nutritionally was in standard condition,hence,it could be used as a promising feed resource for ruminant2014-01-01T00:00:00ZINFLUENCE OF DIETARY ENERGY AND PROTEIN INTAKE ON YIELD AND COMPOSITION OF MILK IN CROSSBREDNATH, SABUJ KANTIhttp://dspace.cvasu.ac.bd/jspui/handle/123456789/26822024-01-15T05:35:10Z2014-01-01T00:00:00ZTitle: INFLUENCE OF DIETARY ENERGY AND PROTEIN INTAKE ON YIELD AND COMPOSITION OF MILK IN CROSSBRED
Authors: NATH, SABUJ KANTI
Abstract: The study was carried out on 120 crossbred Holstein X Shahiwal dairy cows for a period of 150 days to quantify the influence of dietary energy and protein intake on yield and composition of milk. Total 12 dairy farms having similar housing systems and holding at least 20 dairy cows in between mid to late lactation were selected for study purposes. The farms were located in the peri-urban and urban areas of Chittagong, Bangladesh. Milk samples were collected from individual cow. Milk from cows having same BCS were mixed together to make a composite sample. Chemical analyses of the samples were carried out in triplicate for fat, protein, lactose, total solids (TS), solids not fat (SNF) and ash. Dietary Metabolizable Energy (ME) and crude protein (CP) intake were measured by analyzing the amount of total mixed ration ingested by the individual cow. Results indicated that, ME intake (MJ/d) significantly (P<0.01) influenced milk yield, milk fat and TS content of milk in crossbred Holstein Friesian dairy cows. Similar to ME, CP intake (g/d) also influenced (P<0.01) milk yield, fat, protein, lactose, TS and ash content of milk. Correlation coefficient matrix indicated that, milk yield was positively correlated with ME and CP intake. However, there was a negative association between ME or CP intake and milk protein, lactose, TS and SNF of milk even though the strength of association was variable. It could therefore be inferred that, adequate dietary ME and CP intake is important to optimize milk yield and milk composition in crossbred Holstein X Shahiwal dairy cows reared under intensive farming systems in tropical regions2014-01-01T00:00:00ZNUTRITIVE VALUE AND DIGESTIBILITY OF LIMPOGRASS (BAKSHA GRASS)http://dspace.cvasu.ac.bd/jspui/handle/123456789/26812024-01-15T05:07:43Z2014-01-01T00:00:00ZTitle: NUTRITIVE VALUE AND DIGESTIBILITY OF LIMPOGRASS (BAKSHA GRASS)
Abstract: The present study was undertaken to observe the chemical composition and digestibility of Limpograss (Hemarthria altissima) available in low land area in Bangladesh. Chemical analyses of the samples were carried out in triplicate for moisture, dry matter (DM), crude protein (CP), crude fiber (CF), ether extracts (EE) and total ash in the animal nutrition laboratory, Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh. Data was calculated for all samples by using standard formula. The nutritive value of Limpograss was analyzed and found as DM (30.00%), moisture (70.00%), CP (8.75%), CF (31.75%), EE (2.04%) and Ash (11.30%). The nutritive value of Limpograss after digestion was also analyzed and found as DM (14.25%), moisture (85.75%), CP (4.67%), CF (20.85%), EE (0.61%) and Ash (8.58%). The results showed that digestibility of dry matter, crude protein, crude fiber, ether extract and Ash in Limpograss were 52.50, 46.63, 34.33, 69.90 and 23.84 per cent, respectively. Results indicated that, the digestibility of Limpograss was higher than any other available grasses in Bangladesh, except the crude protein content. However, Limpograss nutritionally was in standard condition, hence, it could be used as a promising feed resource for ruminant.2014-01-01T00:00:00Z
