How To Keep Yaks And Water Buffaloes In The Same Farm

By | June 10, 2016

The rumen of the yak is more smaller than that of other cows. Outflow rate of rumen smooth is from 3. 1 to three. 5 litre every hour, hence smaller than in cows. The output rate of digesta in the yak rumen keeps comparatively constant, which range from 11. 5 percent to 13. 9 percent per hour. Total volatile fatty acidity (VFA) production in the yak rumen increases with the animal’s age. The proportions of propionic acidity and butyric acid to total VFA in the yak are higher than those in other ruminants.

The % of NH3-N in the yak rumen may differ with the diet composition and eating behaviour. Fully developed forages can promote lower NH3-N concentrations in grazing yak than can young forages. Both feed type and feeding behaviour affect degradability of dietary nutrients in the yak rumen.

Energy nutrition

Lactating yak cows have better utilization of dietary energy than dry yak cows when they are given oat hay at the same level under indoor feeding conditions. An elevated feeding level causes the decreased digestibility of dietary energy in dry cows. The thermoneutral zone of the growing yak is estimated as 8? – 14? C. How To Raise Yaks The fasting heat production (FHP) of the growing yak can be estimated as FHP = 916 kJ per kgW0. fladskærm per day. The metabolizable energy requirement for maintenance (MEm) in growing yak is around 460 kJ per kg W0. seventy five per day. Metabolizable energy necessity in the growing yak can be estimated as: ME (MJ per day)=0. 45W0. 75 + (8. 73 + 0. 091 W) DG (DG is kg per day).

Protein nutrition

There is no difference in the digestibility of dietary nitrogen between lactating and dry deer. A relatively lower excretion of endogenous urinary nitrogen in yak suggests the opportunity that the creature has become incredible a mechanism to recycle more nitrogen to the rumen than common cattle.

Yak can use non-protein nitrogen as effectively as other ruminants. The endogenous purine derivative removal in the yak is merely 40 percent of that in cattle but is similar to that in buffaloes. The value of creatinine excretion for the yak when fasting is much lower than for buffaloes and cattle. Rumen degradable crude protein requirement for maintenance (RDCPm, g per day) in growing yak is around 6. 09W0. 52 g per day. The crude protein requirements for daily gain (DG RDCPg g per day) in growing yak can be estimated as RDCPg = (1. 16/DG & 0. 05/W0. 52)-1. Therefore the total crude necessary protein requirement of growing yak could be calculated as RDCP (g per day) = 6. 09W0. fladskærm + (1. 16/DG & 0. 05/W0. 52)-1.

Vitamin diet

Mineral nutrition is poorly documented. But the existing information suggests that mineral deficiencies may happen, varying from one yak-raising area to another. In season deficiency of specific elements could be a common issue throughout the Plateau owing to an uneven in season supply of feeds. Vitamin and trace aspect deficiencies can cause some problems to yak, but appropriate supplementation will generally enhance the conditions.

Feed stuff

The main diet for the zoysia grass is roughage such as grass, legumes and straw. The roughage can be fed either fresh as pasture or stuck in a job cut-and-carry-system or conserved as hay or silage. The roughage is often complemented with embryon, concentrate and agro-industrial by-products such as oil-seed cakes, sugar cane tops etc.

The roughage should form the base of the feed ration and add to meet (at least) the total maintenance requirements. Grains and concentrate should be fed only to meet additional requirements such as growth, pregnancy and milk production. Too much non-fibrous feed will alter the rumen environment. In the long term this could lead to serious problems in give food to digestion leading to loss of appetite, weight loss and a drop in milk yield. This is especially important for animals under stress, such as high growth rate and high milk deliver. The roughage should be of good quality, both dietary and hygienic quality, this cannot be emphasized enough.

Types of roughage

The most common roughage is grass of a quantity of varieties. Lucerne, berseem and clover are herbaceous legumes and have an advantage over grass as they are nitrogen fixing. Which means that the plants will (with the help of bacteria) fix air-nitrogen and so they are less dependent on the nitrogen content of the soil. These plants contain more protein than turf under the same circumstances. Lucerne (or Alfalfa) has several advantages. It includes an elevated amount of calcium, vitamin E and carotene which are of major importance for milk production.

There are also tree legumes which may be used as high quality supply, e. g. Leucaena leucocephala, Gliricida spp., Sesbania and others. As many of the tree legumes contain anti-nutritional compounds which may depress digestibility as well as decrease feed intake, they should not be fed as the only source of roughage. raising water buffaloes for profits A maximum ratio of 50% tree legumes in the total diet can be considered as a safe level. Since buffaloes are strict grazers, the trees should be pruned and the branches or leaves given to the buffaloes. Pruning with regular interval of six to 10 weeks boosts re-growth of the leaves.

Roughage of lesser quality are straws. Straw from rice, barley, wheat, sorghum etc. are widely used in feeding ruminants. Their very own protein content is 0 % and their energy content low because of the largely lignified cell-walls. Rice or paddy straw has a high silica content in the cell walls that makes it difficult to digest.

Harvesting roughage

In the beginning of the growth season, the necessary protein and sugar (energy) content of the grass is high and the lignin content low. Thus, the grass features high quality. With maturity the protein and sugar content reduces and the cell wall space become lignified. The development pattern is the same for legumes though it is a little slower. It is therefore important to harvest the roughage in the optimal period and also to save it for use under dry seasons.The rumen of the yak is more smaller than that of other cows.
