Silage or Murghas and related products questions and answers :
The acid environment of the silage eventually reduces the activity of the enzymes that break down proteins.This is an anaerobic fermentation in which the growth and development of acetic acid-producing bacteria occurs. These bacteria ferment soluble carbohydrates and produce acetic acid.
L = Length of Silage (ft) When full length bags are used, the length of silage is the bag length minus the unused portion needed to seal each end of the bag. The quantity of dry matter in the bag is the volume multiplied times the dry matter density.
Silage can also be made from forage and small grain crops. The biggest risk factor associated with feeding silage to sheep and goats is the risk of listeriosis. … The major source of listeria in sheep and goats is from eating poorly fermented or moldy silage.
Corn silage is a popular forage for ruminant animals because it is high in energy and digestibility and is easily adapted to mechanization from the stand-crop to time of feeding. Corn silage should have a light, pleasant smell with only a slight vinegar odor. It should be slightly brown to dark green.
It is not unusual to get foul, putrid smells in wet cereal and grass silages, and particularly in alfalfa silage. This smell is most associated with clostridia, which utilize soluble sugars or organic (lactic) acids to produce butyric acid (which has a rancid butter smell).
A gestating cow will easily consume about 2.5% of her body weight on a D.M. basis of corn silage. If the cow weighs 1200 pounds, she could consume on a daily basis 30 pounds of silage on a D.M. basis. If the silage is 35% D.M., this 1200 pound cow could eat 86 lb (30 lb/.35 = 85.7 lb) of silage daily.
Three to four weeks Traditionally, nutritionists have recommended allowing silage to ferment for three to four weeks before feeding, although recent research from Cumberland Valley Analytical Services Inc. (CVAS) indicates waiting longer may increase silage digestibility.
Silage must be filled rapidly, packed well, sealed carefully, and immediately covered to reduce spoilage losses. Silage inoculates in the top 1 to 2 feet help reduce spoilage and extend silage bunk-life. Store silage in bunker silos at moisture contents of 62 to 68 percent.
Today the most common definition is that haylage is drier than silage, and some haylage is so dry it is hay wrapped in plastic. In the feeding experiments presented on this website forage with dry matter (DM) concentrations between 50-70% are called haylage and between 35-50% are called silage
The word silo comes from the Greek word ‘siros’ which means a hole or pit in the ground for storing corn. It is known that the Greeks and Egyptians were familiar with ensiling as a technique for storing fodder as far back as 1000 to 1500 BC.
The main difference between hay and silage is that the hay is grass cut and dried to use as animal fodder whereas silage is the fermented, green forage fodder stored in a silo. The moisture content of hay is not more than 12% while that in the silage is 40-60%.Both crops are made up of grass.
Question:मुरघास म्हणजे काय ?
हिरव्या वैरणीतील उपलब्ध पोषण मूल्य घटकांचे जतन करणेसाठी (हिरव्या वैरणीची प्रत व दर्जा कायम राखण्यासाठी) अतिरिक्त हिरवी वैरण योग्य वेळी कापणी करुन वैरणीत 30 टक्के शुष्कांक (ड्रायमॅटर) व 70 टक्के आर्द्रता असतांना कुट्टी करुन खड्डयात (घ्त्द्यद्म) मध्ये हवाबंद स्थितीत (अनअेरोबीक कंडीशन) मुरण्यासाठी/आंबविण्यासाठी (फरमंटेशन) साठविली जाते. या हिरव्या वैरणी साठविण्याच्या / टिकविण्याच्या पध्दतीला मुरघास बनविणे संबोधिले जाते.
Question: उत्तम मुरघासाची वैशिष्टये?
- 1. वास : चांगल्या तयार झालेल्या मूरघासास आंबट असा वास येतो.
- 2. रंग : मूरघासाचा रंग फिक्कट हिरवा किंवा तपकिरी दिसतो.
- 3. आम्लता : मूरघासाची गुणवत्ता आणि आम्लता याचां परस्पर संबध आहे. उत्तम दर्जाच्या मूरघासाचा सामू (पी.एच.) 3.5 ते 4.5 असतो.
- 4. ओलावा : मूरघासामध्ये 75 ते 85 टक्के पाण्याचे प्रमाण असते.
मूरघास व ताजी हिरवी वैरण यांची पोषणमूल्यदृष्टया तूलना होणे जरी शक्य नसले तरी हिरवी वैरण साठवून ठेवण्यासाठी मूरघास ही एक चांगली पध्दत आहे.
