HAY MAKING :-
Hay :- It is refers to the grasses or legumes that are harvest dry and store as 85-90% dry matter and is pale green to pale gold in colour. this is leafy and easily peliable. It is also free from mustiness. and can be utilize as an excellent feed for dairy cattle.this is rich in protein, vitamins and minerals. this should be cut at mid bloom stage.( 50% flowering). It is low moisture content( 10-15%).
*KINDS OF HAY :-
1.) LEGUME HAY:- It has higher percentage of digestable nutrients, higher protein content of superior quality. It has higher vitamin content specially rich in keratin, vitamin E. Legume hay are generally rich in calcium and are peliable. Crops:- Barseem, lucern, Cowpea
2.) NON-LEGUME :- It is less peletable and less amount of protein, vitamin nutrients. It is rich in carbohydrates. Crop:- oat, barley, bajra, sorghum and many grasses.
3.) MIXED HAY :- The nutrientive value of mixed hay depends upon the type of legume and non- legume crops used in mixed hay.
MTHODS OF MAKING =
:- 1.) FIELD CURING :- The herbage is allow to lie in field for few hours then it is put on pack in small loose heaps known as windrows. In order to hasten curing the windrows can be turn after few hours.
2.) BY HANGING ON Tripot:- There are three pole are fix on ground at different height or which the crop is hang. Racks:- On the higher spot at the corner of field iron bars are post across each other and the crop is put on it.
3.)COCKS AND STAKING – It is tie into bundles in beginning when moisture content is high. The bundles are kept erect supporting each other for easy circulation of air and when moisture content is reduce then bundles are kept in stacks.
4.)MODERN METHOD :- It is chopped in small pieces. Electrical drying:- Hot air is passes through the small pieces until the moisture content is less than 12% Shade drying:- In this method, material is dries in thin layers for quick drying.
*LOSSESS OF NUTHRITION IN HAY MAKING :-
protein Storage of hay:- Usually store in stacks in shady place where there is no danger of fire. Stacks should be on elevate place.
