Straw feed fermentation operation method

Straw, due to its hard and fibrous texture, is difficult for animals to chew directly, leading to poor palatability and low nutritional value. Freshly harvested wheat and rice straw, as well as dry straw, are high in cellulose but low in protein and soluble sugars. Feeding these types of straw to cattle and sheep can negatively impact their feeding behavior and overall productivity. To improve this, straw fermented feed is produced by adding microbial inoculants, such as the Jinbao straw fermenting agent, which helps break down the tough fibers. Under the action of these microorganisms and enzymes, the straw becomes soft, moist, and more appealing to livestock. Here’s how to produce fermented feed using the Jinbao straw starter:

1. Prepare the raw materials by cutting or shredding them into small pieces. For cows, horses, and quail, cut the straw into 1-2 cm lengths. For sheep and deer, use 1 cm pieces. For pigs, chickens, ducks, geese, and rabbits, it's better to crush the straw into smaller fragments.

2. The recommended dosage is 1 kg of fermenting agent per 500 kg of dry straw. First, mix the starter with warm water (30-35°C) and then combine it thoroughly with the prepared straw. Ensure the moisture level is around 60-70%. A simple test is to grab a handful of material—if no water drips from your fingers, the moisture is just right.

3. Pile the mixed straw into a heap approximately 50 cm high. The length and width can vary depending on the quantity. Insert a thermometer and cover the pile with a heat-retaining and moisture-retaining material to start fermentation.

4. In summer, fermentation usually takes 6-8 hours. During winter, if the temperature is above 15°C, it may take 16-24 hours. If the ambient temperature is below 15°C, try to raise it to at least 15°C. Using insulation on the pile can speed up the process.

5. Once the temperature reaches 40°C, turn the pile over. Be careful not to let it exceed 45°C, as this could lead to over-fermentation. It's best to turn the pile 1-2 times during the entire process. When the straw turns yellow and emits a pleasant sour smell, the fermentation is nearly complete. At this point, remove the cover and allow the temperature to drop to prevent secondary fermentation.

Additionally, corn stover has a waxy layer that is harder to break down. Soaking it in lye before fermentation can help improve the results. Using the Jinbao straw fermentor not only enhances the nutritional value of the feed but also reduces farming costs and promotes sustainable resource use. This method is an effective and practical solution worth promoting and applying widely.

Isolated Whey Protein

Whey protein then undergoes another process to make one of three main types:

1. Concentrate: Products with whey protein concentrate vary widely in their protein, lactose and fat content. Whey protein concentrate is in many protein drinks, bars and nutritional products. It’s also used in infant formula.

2. Isolate: This type is consistently high in protein and low in fat or lactose. You may see it listed on the labels of protein supplements, such as bars and drinks. Whey protein isolate may be a suitable choice for people who are lactose intolerant — but don’t try any of these if you have a milk allergy.

3. Hydrolysate: Also known as hydrolyzed whey protein, whey hydrolysate is the easiest to digest. It’s gentle on digestion because its long protein chains, called peptides, are pre-broken down into shorter ones. Specialized infant formulas often use hydrolyzed whey protein. You may also see it in medical supplements for nutritional deficiencies.

Whey protein may be useful for:

· Muscle building: Muscles love protein, especially complete proteins like whey. “Whey protein contains branched-chain amino acids, a specific type of amino acid that helps with muscle building,” Smith says.

· Wound healing: The amino acids in whey protein help repair skin and tissues from wounds or surgery.

· Weight gain and nutritional boost: People who need to gain weight can benefit from whey protein. It’s also helpful if a person has a long-term illness and needs extra nutrition. “If you can’t get enough protein from whole food sources, a whey protein supplement can help,” says Smith. “It’s beneficial for people who have chewing or swallowing disorders or a lack of appetite.”
