Harvesting Maize at the Milky Stage: Benefits for Silage MakingGive two reasons why maize should be harvested at milky stage for silage making.
Detailed Answer:
Maize should be harvested at the milky stage for silage making due to two main reasons:
Name four practices used by farmers to reduce the temperature of a silo during silage making18/11/2023 Practices to Reduce Silo Temperature during Silage MakingName four practices used by farmers to reduce the temperature of a silo during silage making.
Four Practices to Reduce Silo Temperature during Silage Making
Farmers employ various practices to reduce the temperature of a silo during the process of silage making. Here are four commonly used practices:
Qualities of Good Silage: Lactic Acid Content, Absence of Moulds, Fresh Color, and Optimal pHOutline four qualities of good silage.
Outline: Four Qualities of Good Silage
Good silage possesses several qualities that indicate its high quality and suitability for livestock feeding. Here are four key qualities of good silage:
Factors Influencing the Size of a Silage Pit: Animals to be Fed and Length of the Dry SeasonGive two factors that determine the size of a pit for silage making.
Detailed Answer:
There are two factors that determine the size of a pit for silage making:
Considering these factors allows farmers to determine the appropriate size of the pit for silage making, ensuring an adequate supply of feed for the animals and effective management of the feed resources. The Procedure of Silage Making: From Harvest to FeedoutOutline the procedure of making silage
Detailed Answer:
Making silage involves a step-by-step procedure to ensure proper fermentation and preservation of the forage. The procedure typically includes the following steps:
Give one reason why too much air in the silo is undesirable in the process of making silage18/11/2023 The Undesirability of Excess Air in Silo during Silage MakingGive one reason why too much air in the silo is undesirable in the process of making silage.
Detailed Answer:
One reason why too much air in the silo is undesirable in the process of making silage is that it may cause decomposition. When there is excess air present in the silo, it provides an oxygen-rich environment. This oxygen allows aerobic bacteria and fungi to thrive and break down the organic matter in the silage through the process of decomposition. Excessive decomposition of the forage can lead to spoilage, resulting in a loss of nutrients, foul odors, and reduced palatability. Decomposed silage is not suitable for feeding to livestock as it can negatively impact their health and performance. To prevent decomposition, it is essential to minimize the amount of air within the silo. Proper compaction during the filling process helps remove air pockets and create a dense, airtight environment. Additionally, sealing the silo with an oxygen barrier film or plastic cover helps prevent air ingress and creates an anaerobic condition that inhibits the growth of aerobic bacteria responsible for decomposition. By minimizing the presence of excess air, farmers can reduce the risk of decomposition and ensure the preservation of high-quality silage for optimal livestock feeding. The Beneficial Effect of Low pH in Silage MakingWhat is the effect of low pH is silage making.
Detailed Answer:
The effect of low pH in silage making is highly beneficial. A low pH inhibits bacterial growth and plays a crucial role in preserving the silage. During the ensiling process, when forage is packed and sealed in a silo, lactic acid bacteria (LAB) begin to ferment the sugars present in the forage. As LAB consume the sugars, they produce lactic acid. This lactic acid production leads to a decrease in the pH level of the silage. The low pH achieved through lactic acid fermentation has several effects:
Overall, the effect of low pH in silage making is crucial for inhibiting bacterial growth, preserving the silage, and maintaining its nutritional quality. Undesirability of Excess Air in Silo during Silage MakingGive two reasons why too much air in silo is undesirable during process of silage making.
Detailed Answer:
There are two main reasons why too much air in a silo is undesirable during the process of silage making:
By minimizing air exposure, farmers can promote the proper fermentation and preservation of the silage, ensuring that it retains its nutritional value and remains suitable for feeding to livestock. |
