Methods to Evaluate Rumen Protected Lysine for Dairy Cows

In vivo testing procedures are complex, time consuming and expensive. This study was conducted to determine if a newrapid, lower cost in vitro method developed for feed ingredients could be applied to a rumen protected lysine product (DairynatLys-30, Jefo Nutrition Inc).

Dietary Supplementation of Rumen

Nov 18, 2015In addition to basal diet, animals in second group (rpMetLys) were fed with 5 g of rumen-protected methionine and 20 g of rumen-protected lysine, and in third group (rpCholine), 54 g of rumen-protected choline was supplemented 40 days before and 120 days after calving.

Effects of rumen

Abstract. A series of trials was conducted to determine the effects of supplemental rumen-protected methionine (RPMet) and lysine (RPLys) on nutrient metabolism and performance. In situ RPMet N disappearance was less than 4% following 48 h of incubation and was not affected (P greater than .05) by diet or resultant ruminal pH differences,

New Research Highlights the Role of Rumen Protected

The researchers found that this could be done when using a reference rumen-protected amino acid supplement with a known bioavailability. According to the research results, the bioavailability of the test product used was 20.8% relative to the reference rumen protected methionine. The use of ruminally-cannulated cows was shown to not be needed.

The effect of liquid "rumen protected" lysine

The rumen protected lysine product evaluated did not improve cow productivity, probably because the product was either unprotected from rumen degradation, or overprotected to the extent that the lysine was not available for absorption in the small intestine; or absorbed but could not be metabolised.

Four trials were conducted to determine the effects of supplemental rumen-protected methionine (RPMet) and lysine (RPLys) on lamb N metabolism and steer feedlot performance. In trial 1, 20 Suffolk-sired, crossbred lambs (avg weight 32 kg) were fed diets containing no supplemental methionine (Met) and lysine (Lys), .03% RPMet, .05% RPLys or .03% RPMet + .05% RPLys.

Transition cows require both methionine, choline

Piepenbrink and Overton (2003) determined that cows fed rumen-protected choline (RPC) during the precalving period and on through early lactation tended to have increased fat-corrected milk yields (average response of 5.3 lb. per day) during early lactation, along with a trend for decreased storage of radio-labeled palmitate as liver triglycerides in vitro and increased concentrations of liver glycogen,

May 18, 2012Rumen-protected amino acids are nutrients and, as such, have the ability to accentuate the biology of the cow and facilitate the use of other dietary ingredients to better meet the production, health and reproductive needs of the animal at all stages of lactation and levels of production.

More Concentrated AjiPro

The new AjiPro-L raises the industry standard for supplemental rumen-protected lysine. It offers 80 percent rumen bypass and digestibility of more than 60 percent in the small intestine. Two plasma lysine studies, one at the University of New Hampshire and another at the W.H. Miner Institute, revealed that the new AjiPro-L was 30% to 40% more bioavailable than the first generation product.

LYS

Rumen by-pass Lysine HCl. Lys–by is a microencapsulated Lysine HCl protected by a pH sensible lipid matrix in order to by-pass the rumen and be highly available in the gut. Due to its particular chemical structure, Lys-by is resistant to mixing, grinding and pelletizing. Lys-by combines high rumen bypass value with high bio-availability of Lysine in the gut.

USA LYSINE PROTECTED AMINO ACID

Lysine is one of the two first limiting amino acids in a lactating dairy cow's diet. USA Lysine is protected so that it escapes the rumen at a high rate but is very available in the intestines where it is absorbed by the cow. One-hundred grams of USA Lysine is equivalent to 44 grams of mLys, the highest mLys concentration of any protected lysine product currently on the market.
