Ruminal degradation, amino acid composition, and estimated intestinal digestibilities of four protein supplements

Journal of Dairy Science
M S Piepenbrink, D J Schingoethe

Abstract

Blood meal, canola meal, corn gluten meal, and menhaden fish meal were weighed into dacron bags for incubation in the rumens of two ruminally cannulated Holstein cows on 3 d for 0, 3, 6, 12, 18, and 24 h. Both the original feeds and the residues remaining after 12 h were analyzed for amino acid (AA) content. Canola meal was degraded the most extensively in the rumen, and blood meal was degraded the least extensively. Intestinal digestibilities estimated using an enzymatic in vitro technique were all high; canola meal was estimated to have the lowest intestinal digestibility, and corn gluten meal was estimated to have the highest intestinal digestibility. The AA profile of the 12-h residues differed only slightly from the AA profile of the original protein supplements. A comparison of the AA profiles of feed residues with milk protein showed that isoleucine was the first-limiting AA in blood meal, canola meal, and fish meal, and lysine was the first-limiting AA in corn gluten meal. Although canola meal was extensively degraded in the rumen, its 12-h residue still provided an estimated AA profile to the intestinal tract that was closest to the AA profile of milk protein. Blood meal and corn gluten meal are good sources of ruminal...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
