Raising Water Buffalo For Beginners

Raising Water Buffalo Water Buffalo Feeding Guide Buffaloes are, like cattle, ruminants. This means that they utilize micro-organisms in the rumen to digest the feed. The feed eaten by ruminants are mainly of vegetable origin. The ruminant is an expert in converting cellulose and other fibrous materials into high quality milk and meat. Their digestive capacity is greater than the non-ruminant. Ruminants” chew the cud" e.g. regurgitate the food to the mouth and chew it several times, thus helping the breakdown. The feed will enter the rumen compartment when swallowed by the animal. The rumen is an anaerobe environment, e.g. no oxygen is present. The feed is exposed to microbes such as bacteria, protozoa and fungi. These microbes attack the feed particles and by enzymatic action the components are broken down and used for their own metabolism, growth and propagation. The feed is masticated, regurgitated and exposed to microbes in the rumen. Large particles will become smaller and eventually be transported to the reticulum and further on. How long time a specific feed particle will stay in the rumen depends on size, palatability and fiber content of the feed. The buffalo has slower rumen movement than cattle, which leads to a slower rate of ingest outflow. The pH of the rumen content is similar to that of cattle, and it is affected in the same manner. Normal pH is between 6 and 7 depending on feed and time of feeding. The components of the feed can be divided into protein, energy (carbohydrates), fat, minerals and water. The breakdown and utilization of the different feed components are reviewed below.The waste end products of the microbial attack are methane and carbon dioxide which are eructated. Volatile fatty acids (VFA) of which acetic, prop ionic and butyric acids are the predominant ones, are together with ammonia absorbed by the animal through the rumen wall, and transported via the blood to, e.g. the liver and udder where they serve as building material for chemical compounds such as glucose, protein and fat (see Figure 10). Ammonia can be utilized directly by the rumen microbes to synthesize proteins. To be correct, one is actually not feeding the buffalo, but its’ microbes. Ruminants are entirely dependent on the function of the rumen microbes. Therefore, it is important to keep the rumen environment healthy. The easiest and best way is to feed a high amount of good quality roughage and a smaller amount of good quality concentrate. Protein Almost all protein is attacked by the microbes and utilized in their metabolism and incorporated in the microbial mass. Microbial protein is of high quality and is absorbed as amino acids after being digested by gastric enzymes in the abomasums. Ammonia which is absorbed by the rumen wall and transported by the blood to the liver, is converted to urea. In case of protein deficiency, urea can be utilized by the rumen microbes as a non-protein nitrogen source to build protein. In this way nitrogen is circulated and efficiently used by the animal. Protein can be protected to withstand microbial attack. It is then called”by-pass protein”. By-pass protein is only degraded in the abomasums and small intestine where it undergoes enzymatic attack similar to that of mono-gastric animals. By-pass-protein is commercially available in some ready made concentrates and is usually given to high producers. Carbohydrate Carbohydrates are the predominant sources of energy for ruminants. Carbohydrates, or sugars, are the components of starch and fibers. Fiber is a common name for cell-wall components such as cellulose, hemi-cellulose and lignin. Starch can be degraded by animal gastric enzymes, whereas fibers cannot. Ruminants can utilize fibers to a larger extent than mono-gastric animals because of the ruminal microbes. However, lignin (wood-fiber) is not utilized. It is generally believed that buffaloes utilize fiber more efficiently than cattle do. The coefficient of digestion is 5-8% higher in buffaloes than in cattle. Fat Fat is not as such required in other than very small amounts for the ruminant. However, what ever fat is present in the feed undergoes microbial attack and degradation. Unsaturated fatty acids are hydrolyzed and thus saturated. This is one of the reasons for the milk and body fat of the ruminant to be of equal composition, largely independent of the type of feed given. If the fat can in some form be protected from ruminal degradation, and instead be utilized in the lower intestinal tract, it may be used as an additional energy source. However, it may then alter the milk fat composition unfavorably. Too much unprotected fat in the diet depresses the ability of the microbes to ferment fibers, thus influencing the energy utilization negatively. Water Buffalo Management Irrespective of breed, season or time of day, body temperature, respiration rate and pulse rate of buffalo in the shade is lower than that of cattle. These physiological differences often lead to buffalo being incorrectly considered to have a better heat regulatory mechanism. Management methods to ameliorate adverse effects of physical environment. Housing Housing needs to be very simple, because the winter is mild and the rain fall medium, with severe heat in the summer. Such a climate calls for open structures allowing plenty of air movement to keep heat stress to a minimum. A system of loose housing is best for these conditions and also saves on labour. A system for a herd of 20 cows was devised at the National Dairy Research Institute Karnal. This consists of a roofed shed 40'x15' (about 12.5 m x 4.5 m), along the 40' length on one side is a 2.5' (0.75 m) wide manger, with a water trough at one end. The remaining 12' (3.75 m) of the 15 ft (4.5 m) covered space is concreted and slopes away from the manger. There is an open paved area behind measuring 40'x35' (12.5 m x 10.75m) surrounded by a 5' (1.5m) wall with a gate (Sundaresan 1973). Wallowing and bathing Water buffaloes like to wallow in fresh water in herds. In hot weather, perhaps due to their thick subcutaneous fat layer and less developed sweat glands, buffalo are more comfortable while wallowing. Even sprinkling of water or showering and splashing makes buffalo comfortable. Wallowing buffalo seek out rivers, ponds and other waters in groups of five to ten animals clustered together. When sufficient water is not available particularly in the summer months, they lie in the mud to keep their body cool. Wallowing tanks should be provided on large farms and animals in small numbers should be washed or showered once or twice a day. Various thermal ameliorative measures that have been tried include wallowing, mud plastering, sprinkling, splashing, body wetting with small quantities of water and providing cool drinking water (Pandey and Raizada 1979). Simple body wetting two to three times during the hottest part of the day was found to keep buffalo in a reasonably comfortable condition as judged by their physiological reactions (Sastry and Tripathi 1988). Summer sub-fertility Despite the evidence of some intrinsic hormonal constraints in the buffalo (Madan 1987), the problem of long intercalving periods seems to be due to environmental factors, and can be controlled by the farmer (Sastry and Tripathi 1988). Bhat et al (1983) observed that buffalo cows continue to come in heat regularly in all months, the highest incidence being after a period of wet season feeding. However, conception rates at this time are lower due to poor semen quality of buffalo bulls. Buffalo protected from high ambient temperature and direct solar radiation, and with adequate nutrition, show higher reproductive performance (Acharya and Bhat 1989). Management practices involving provision of shade and application of water to the skin surface reducing the adverse effects of a hot environment and improving estral expressivity and thus reducing seasonality of breeding, should be adopted. In addition, low levels of nutrition appeared to increase the length of the oestrus cycle.
