Abstract A 6-week feeding trial was carried out to investigate the optimal calcium level in the diet of quail chicks in Nigeria. Four isonitrogenous (25% crude protein) diets containing 0.5, 1.0,1.5 and 2.0% dietary calcium were employed in the trial which involved 480) day-old, uncensored quail chicks. The diets were also isocaloric (2750 kcal/kg M. E). Each dietary treatment was replicated three times. Responses measured included weight gain, feed consumption and feed conversion ratio. Feed intake was higher in diet A (P<0.05) in comparison to others. Diet D recorded lower feed intake (P<0.05) than Diets B and C. Weight gain was similar (P>0.05) for Diets A, B and C which were better than diet D (P>0.05). Feed conversion was better with Diets C And D (P<0.05) than with diets A and B. Diet A was poorer (P<0.05) than diet B in terms of feed conversion. Feed cost/gain ratio was lower (P<0.05) on Diet A than others. Percent bone ash was similar on the diets except Diet C. Results of this study indicated that dietary calcium levels of between 0.5 and 1% will support acceptable weight gain and % bone ash in the first 6 weeks of life.

Fifty-two Yankasa lambs of mixed sexes age, 6 to 8 months, were used in this study to determine calcium requirement. Varying levels of dietary calcium viz: 0.28, 0.42, 0.56, 0.70, 0.86, 0.99 and 1.15% were tested in a Completely randomized design. Phosphorus was kept constant at the level in the control ration. The criteria of adequacy employed included clinical observations, growth performance and mineral retention. No clinical abnormality was Observed among the groups throughout the experimental period. Although growth performance improved with increase in dietary calcium level, treatment effects among groups on 030, 0.86, 0.99 and 1.15% dietary levels were not significant (P > 0.05). Apparent dry matter digestibility and calcium retention improved with increase in dietary calcium. Mean calcium requirement for lambs was 305 mg/day/kg body weight. Comparisons with the findings of some temperate workers showed that while the endogenous calcium loss for lambs in this region was lower, their requirement for calcium Was higher than those in the temperate region

Findings of studies on the link between dietary acid-base balance and bone mass are relatively mixed. We examined the association between dietary acid-base balance and bone mineral density (BMD) in a sample of Iranian women, hypothesizing that a higher dietary acidity would be inversely associated with BMD, even when dietary calcium intake is adequate. In this cross-sectional study, lumbar spine and femoral neck BMDs of 151 postmenopausal women aged 50 - 85 years were measured using dual-energy x-ray absorptiometry. Dietary intakes were assessed using a validated food frequency questionnaire. Renal net acid excretion (RNAE), an estimate of acid-base balance, was then calculated indirectly from the diet using the formulae of Remer (based on dietary intakes of protein, phosphorus, potassium, and magnesium; RNAERemer) and Frassetto (based on dietary intakes of protein and potassium; RNAEFrassetto), and was energy adjusted by the residual method. After adjusting for potential confounders, multivariable adjusted means of the lumbar spine BMD of women in the highest tertiles of RNAERemer and RNAEFrassetto were significantly lower than those in the lowest tertiles (for RNAERemer: mean difference -0.084 g/cm2; P=0.007 and for RNAEFrassetto: mean difference - 0.088 g/cm2; P=0.004). Similar results were observed in a subgroup analysis of subjects with dietary calcium intake of >800 mg/day. In conclusion, a higher RNAE (i. e. more dietary acidity), which is associated with greater intake of acid-generating foods and lower intake of alkali-generating foods, may be involved in deteriorating the bone health of postmenopausal Iranian women, even in the context of adequate dietary calcium intake.
