BYPASS PROTEIN AVAMIX INTENS FOR RUMINANTS

Bypass protein is the part of any ingredient’s protein that is not broken down in the rumen, but is digested in the small intestine by enzymes. It provides the body with high-quality amino acids that are essential for maintaining the animal’s vital functions, as well as stimulating milk production and growth.

Total protein for ruminants is usually divided into fractions.

The RDP fraction (rumen degradable protein) is fermented by microorganisms to nitrogen (N) and used for their vital activity.

Under normal conditions, microbial populations in the rumen are constantly renewed. A certain amount of them regularly enters the small intestine with the feed – this is how ruminants provide themselves with microbial protein.

The bypass protein fraction (RUP) is not broken down by microorganisms in the rumen, but is digested and absorbed in the intestine, providing the animal with a reliable source of metabolic protein, which is so important for milk production.

The amount of microbial protein and the amount of bypass protein (RUP) is the DVE (digestible intestinal protein/metabolizable protein).

The use of commercial products with guaranteed bypass protein content allows you to provide cows with reliable and high levels of metabolic protein without overloading the rumen with excessive amounts of ammonia. This, in turn, increases productivity, improves milk quality, reduces urea levels in milk, and ensures rumen and liver health and reduces culling rates in high-yield cows.

The level of DVE (metabolic protein) in the ration is a driver of cow milk production. The higher the productivity, the higher the level of DVE is required. The potential for microbial protein production in the rumen is limited, so to stimulate high milk production, it is necessary to increase the bypass protein content and maintain it at 95-100mg/kg of dry matter.

There are several ways to control of protein level and protein type.

METHOD 1 – ANALYSIS OF MILK UREA NITROGEN (MUN). The amount of milk urea nitrogen (MUN) is an indicator of the protein feeding and cow health. It helps to assess the efficiency of microbial protein synthesis in the rumen. The norm of milk urea nitrogen (MUN) is considered to be 8-12 mg/dl. However, this numbers is quite individual for each farm.

• A low MUN level (<8 mg/dL) may indicate a deficiency of rumen derived protein (RDP) in the rationor an imbalance in protein and carbohydrate breakdown. It is believed that the potential of the rumenis not being utilized.
• A high MUN (> 12 mg/dL) indicates an excess of rumen protein (RDP), an imbalance of protein and carbohydrate breakdown, and thus inefficient rumen function, otherwise, a lack of energy and fermentable carbohydrates.

The amount of urea nitrogen in milk is a fairly effective indicator for adjusting herd management. Its excess actually indicates an excess of urea in the cow’s body, which has a number of negative factors on the economics of milk production and cow health:

• disruption of rumen function;
• toxic effects on the cattle;
• low efficiency of protein feeding;
• loss of profit;
• decrease in reproduction rates;
• low viability and development of embryos (impact on progesterone levels);
• uterine ph, Mg and K absorption, which negatively affects cow fertility.

METHOD 2 – ANALYSIS OF MILK FAT LEVEL. The lack of available protein in the rumen leads to a decrease in the growth and development of the necessary microbial populations, which in turn reduces the synthesis of volatile fatty acids, in particular acetic acid, thereby negatively affecting the fat content of milk.

METHOD 3 – ANALYSIS OF COW MANURE: Changes in manure consistency are a direct indicator of rumen health. Its visual analysis can help assess the balance of protein and carbohydrate breakdown in the rumen.

Avamix Intens bypass protein has the lowest cost ofmetabolic protein unit (DVE). If you provide a high DVE ration, you can spend less and get more with these products. The products also have a proven positive effect on increasing cow productivity.  Due to its high nutritional value and optimal digestibility, bypass protein increases the economic efficiency of production by reducing feed costs and improving performance.

Cow consumes about 52-57 g of DVE (metabolic protein for every liter of milk produced.). The norm of DVE in the diet of dairy cows is 95-105 g/kg of dry matter consumed, and high-yield cows – more than 100 g/kg DM. Our nutrition consultants will help you find the best solution. If your goal is to increase milk production, it is ideal to take into account the approach of precision and intelligent feeding, where bypass protein can help you.

Yes, Bypass Protein can be effectively combined with other feed additives to create a balanced diet for maximum results.

Bypass protein is suitable for the diets of all ruminants. Young animals that have a poorly developed or undeveloped rumen do not need to be fed bypass protein. For example, these are calves 0-3 months old.
