Having the right kind of high protein cattle feed can ensure that your animals remain healthy and strong. However, there are many different types of high protein cattle feed.

Microbial crude protein
Among the proteins for ruminants, microbial crude protein (MP) is the most important. It is an extremely rich source of amino acids, and provides the majority of protein for the small intestine. It is the product of microbial protein synthesis in the rumen. In order to optimise the supply of amino acids to the animal, the dietary protein must contain sufficient rumen-degradable protein (RDP) and must not leave the rumen undegraded.
The microbial community in the rumen of cattle is a complex one. It is composed of billions of bacteria. This community also undergoes a number of adaptations to its environment. One adaptation is the upregulation of nitrogen recycling in the rumen. The rumen microbiota also modulates feed efficiency. Identifying the ruminal bacterial populations that are involved in this process may provide insight into selecting more efficient cattle for HP diets.
Metabolizable protein
Providing milk to dairy cows requires an adequate supply of metabolizable protein in cattle feed. This is the protein that is absorbed by the intestine. It is also called true protein, as it is available to the animal for useful purposes.
The amount of metabolizable protein in a feed ration is calculated by dividing the milk yield by the DMI. Typically, milk yields are measured twice a day, i.e., at 0500 and 1700 hours. The dietary protein concentration is recommended between 0.21% and 0.25 percent dry matter.
In the study, metabolizable protein was supplied through the microbial protein (MP) system. Specifically, a diet containing 100 g of RPLys per cow per day was fed to cows that were MP deficient. This supplement resulted in a positive MP balance, and provided 89% of the MP requirements.
Alternatives to high-protein cattle feed
Using alternative feeds in your cattle feeding program can have several advantages. In addition to reducing feed costs, they can provide an economic incentive for producers. However, it’s important to note that they may also have unintended consequences.
The best way to decide whether alternative feeds are right for your herd is to consult a livestock nutritionist. A nutritionist can advise you on what feeds are best for your herd, ration balancing, and nutrient recommendations. He or she can also perform feed tests for you.
While there is no one size fits all when it comes to alternative feeds, there are a few general rules of thumb to follow. For example, a balanced ration should include appropriate levels of energy, protein, and minerals. It’s also important to remember that nutrient content increases on a dry matter basis. This means that you should be able to easily compare feeds in terms of the number of pounds of each nutrient per ton.
Grass tetany
Grass tetany is a common cattle disease that affects a variety of animals, including sheep, cattle, and horses. It is caused by magnesium deficiency.
Although grass tetany is generally seen during the spring months, it can occur in the fall, too. If you notice any of these symptoms, contact your veterinarian. It can be serious, and can lead to death. It is important to seek treatment right away.
Clinical symptoms include twitching facial muscles, collapse, frequent urination, and muscle tremors. Grazing away from the herd, hypersensitivity to touch, and hyperexcitability are other symptoms.
Some veterinarians recommend giving a subcutaneous dose of magnesium sulfate. Others use intravenous injections of chloral hydrate, or calcium-magnesium gluconate. However, treatment should only be administered slowly and only by a trained person.
Grass tetany can occur on all stages of cattle, but is most common in older animals. Lactating cows are at the highest risk.
Interval feeding
During the summer grazing season, it’s time to assess the costs of the feeding program. It’s important to figure out how much feed is required for each cow in order to minimize feed and forage waste. This includes optimizing the amount and timing of the RDP and the amount of feed offered to each cow.
In general, feed intake in dairy cows is divided into meals. Each meal is measured according to its characteristics. For example, the length of a meal and its distribution are not necessarily correlated with the milk yield. In fact, they might be inconsequential. Nevertheless, determining the size of a meal is a measure of efficiency in production.
The Insentec system, which monitors the feeding of cattle, records the amount of feed consumed and the number of visits to the bins. The data are then summarized and used to calculate the daily DMI (kg/d).
