Guzerat indicine cattle and A2 milk production

Animal Biotechnology, 2021
Cow milk might be associated to gastrointestinal disorders and abdominal pain in some people, which are, in part, due to the digestion of A1 beta-casein. Within this context, A2 milk has emerged as an alternative since it only contains A2 beta-casein that does not cause these complications. This milk is produced by cows with the A2A2 genotype.

Changes in Metabolites from Bovine Milk with β-Casein Variants Revealed by Metabolomics

Animals, 2020
β-casein is a primary protein in milk, and its variants have been associated with changes in the protein content of bovine milk. However, there has been little research focused on the effects of β-casein variants on milk metabolites. In the present study,

Brazilian consumers’ perception of knowledge regarding the presence of the β-casein polymorphism in milk [PDF]

Ciência Rural
: A2 milk contains the A2 β-casein protein, which does not release the opioid peptide β-casomorphin-7 (BCM-7) during digestion. However, there is limited knowledge among Brazilian consumers regarding the concept, characteristics, benefits, and market ...

Production of Cow’s Milk Free from Beta-Casein A1 and Its Application in the Manufacturing of Specialized Foods for Early Infant Nutrition

Foods, 2017
Beta-casein (BC) is frequently expressed as BC A2 and BC A1 in cow’s milk. Gastrointestinal digestion of BC A1 results in the release of the opioid peptide beta-casomorphin 7 (BCM7) which is less likely to occur from BC A2. This work was aimed to produce

A1 and A2 milk caseins-comparative FTIR and spectroflourimetry analysis

Indian Journal of Animal Sciences, 2021
Around 35% of the total caseins are β-caseins, which are further classified as A1 β-caseins and A2 β-caseins, based on differences in the amino acid composition of both. A2 is the wild type genetic variant of β-casein while A1 is the mutant.

Effects of cow’s milk beta-casein variants on symptoms of milk intolerance in Chinese adults: a multicentre, randomised controlled study

Nutrition Journal, 2017
Background A major protein component of cow’s milk is β-casein. The most frequent variants in dairy herds are A1 and A2. Recent studies showed that milk containing A1 β-casein promoted intestinal inflammation and exacerbated gastrointestinal symptoms ...
