A review of the nutritional and health aspects of goat milk in cases of intestinal resection

Abstract

-The objective of this paper is to review the beneficial effects of the dietary inclusion of goat milk on the utilization of protein, fat and minerals (Ca, P, Mg, Fe, Cu, Zn and Se), which affect malabsorption syndrome caused by resection of the intestine. The consumption of a goat milkbased diet, compared to bovine milk, has shown a higher protein efficiency ratio, protein digestibility, nitrogen balance and food conversion ratio in rats with resection of the distal small intestine. Goat milk diet also improves digestive utilization of fat, reduces fecal losses and decreases plasma triglycerides. Goat milk diet increases the biliary secretion of cholesterol and causes a decrease in plasma cholesterol levels, whereas the levels of bile phospholipids, biliary acid and lithogenic index remain normal. In relation to mineral bioavailability, apparent digestibility coefficients and the balance of calcium, phosphorus, magnesium, iron, copper and zinc are higher after the consumption of a goat milk diet compared to bovine milk diet in resected rats, despite the intestinal absorptive surface being reduced by 50% due to intestinal resection. Based on the particular biological, nutritional and metabolic characteristics, these reports suggest that goat milk can be an excellent natural food in cases of malabsorption syndrome, as an alternative to bovine milk.goat milk / protein / fat / minerals / intestinal resection Article published by EDP Sciences l'inclusion du lait de chèvre dans l'alimentation sur l'utilisation des protéines, des matières grasses et des minéraux (Ca, P, Mg, Cu, Zn et Se) dans le contexte du syndrome de malabsorption causé par la résection de l'intestin. La consommation d'un régime basé sur du lait de chèvre a montré un ratio d'efficacité protéique, une digestibilité des protéines, une balance azotée et un ratio de conversion alimentaire plus élevés chez les rats ayant subi une résection de la partie distale de l'intestin grêle, en comparaison au régime à base de lait de vache. Le régime à base de lait de chèvre améliore aussi l'utilisation digestive des matières grasses, réduit les pertes fécales et diminue les triglycérides dans le plasma. Le régime à base de lait de chèvre augmente la sécrétion biliaire du cholestérol et provoque une diminution des niveaux de cholestérol du plasma, alors que les niveaux de phospholipides de la bile, de l'acide biliaire et l'indice lithogénique restent normaux. En relation avec la biodisponibilité des minéraux, les coefficients de digestibilité apparente et les équilibres en calcium, phosphore, magnésium, fer, cuivre et zinc sont plus élevés après la consommation du régime à base de lait de chèvre en comparaison à celui à base de lait de vache chez les rats résectionnés, malgré une surface intestinale absorbante réduite de 50 % en raison de la résection intestinale. Sur la base des caractéristiques biologiques, nutritionnelles et métaboliques, ces études suggèrent que le lait de chèvre peut être un excellent aliment naturel dans les cas du syndrome de malabs...

Effect ofCSN1S1gene polymorphism and stage of lactation on milk yield and composition of extensively reared goats

“…Goat milk differs from cow, mainly on the basis of its smaller size of fat globules, which cause a better digestibility and higher proportion of short and medium chain fatty acids, which are partly responsible of its stronger flavour (Silanikove et al 2010). Its peculiar properties make it suitable for infants and children, for example in some cases of malabsorption syndrome (Lopez-Aliaga et al 2010).…”

Separation of α-Lactalbumin-Enriched Fractions from Caprine and Ovine Native Whey Concentrate by Combining Membrane and High-Pressure Processing

“…Many studies have highlighted the beneficial effects of goat and sheep dairy products on human health, being considered more easily digestible than cow milk [3,4]. Caprine milk has been described as an alternative for infants with cow milk allergies on account of its nutraceutical and hypoallergenic properties due to its high digestibility and the lower presence of β-Lactoglobulin [5,6].…”

Manufacture and Physicochemical Properties of Chitosan Oligosaccharide/A2 β-Casein Nano-Delivery System Entrapped with Resveratrol

“…Goat milk has been widely used to produce various milk products (Amigo and Fontecha, 2011; Lopez-Aliaga et al, 2010). Compared with cow milk, goat milk has lower allergenicity and higher digestibility due to differences in genetic types of amino acids, which lead to the changes in the digestibility (Haenlein, 2004; Park et al, 2007; Yangilar, 2013; Zhao et al, 2014).…”
