Calcium‐enriched goat milk, in comparison with similarly enriched cow milk, favours magnesium bioavailability in rats with nutritional ferropenic anaemia

Abstract

BACKGROUND: The effects of dietary consumption of goat or cow milk, normal or enriched with calcium (Ca), on magnesium (Mg) bioavailability was evaluated in rats with nutritional ferropenic anaemia. Control and iron-deficient rats were fed for 14 days with iron-normal diets containing either normal (5000 mg kg −1 diet) or high (10 000 mg kg −1 diet) Ca content.

Analysis of 22 Elements in Milk, Feed, and Water of Dairy Cow, Goat, and Buffalo from Different Regions of China

“…Fe, Cu, and Zn concentrations in our goat milk samples were lower than those from Turkey [26] and Saudi Arabia [12]. Additionally, the concentrations of most elements in goat milk were higher than those in cow milk (Table 4), as previously reported [27][28][29]. In the present study, Zn concentration in buffalo milk was five times higher than that in buffalo milk from India, while Fe concentrations were similar between the two studies [30].…”

The effect of formulated goats' milk on calcium bioavailability in male growing rats

“…They theorized, as did López Aliaga et al ,13 that this is in part due to a higher percentage of the more readily absorbed medium‐chain fatty acids found in goat milk. This theory was also shared by Nestares et al 14 on the bioavailability of magnesium, where they found that anaemic rats fed goat milk had greater mineral absorption. Oddly, in terms of bone mineral retention the only significant difference found was between two diets using vegetable oil as their fat source.…”

Effect of calcium-supplemented goat or cow milk on zinc status in rats with nutritional ferropenic anaemia

“…However, in our study, the supplementation of Ca in the diet increased the nutritive utilization of Zn in both in the control and the anaemic rats for the goat milk diet and in the control rats for the cow milk diet. In contrast to previous reports, in the current study the Ca is supplied in part by the milk (cow or goat) and this can be a key factor in the improvement of the Zn nutritive utilization, especially with the goat milk diet, because of its habitual consumption increases the mineral bioavailability, even in NFA (Alfé rez et al, 2006;Campos et al, 2007;Nestares et al, 2008).…”
