“…No influence of avP levels were detected on eggshell (FPP) and albumen (CPP)absolute weights. However, Ribeiro et al (2016) did not find any effect of dietary avP levels on eggshell weight. There was no effect (p>0.05) of dietary avP levels on the absolute weights of the albumen and yolk, independently of dicalcium phosphate particle size, or of the eggshell of birds fed FPP.…”

This experiment was conducted to investigate the effects available phosphorus levels and dicalcium phosphate particle size on the live performance, and egg parameters and bone parameters of Japanese quails in lay. The experimental diets were based on corn and soybean meal and formulated to contain 2900 kcal metabolizable energy (ME) kg-1 , 200 g kg-1 crude protein (CP) and 30.5 g kg-1 calcium (Ca). Feeds were supplied ad libitum. Laying Japanese quails (n=720, 20-wk-old) were distributed in a completely randomized design in a 5 x 2 factorial arrangement, with five levels of available phosphorus (avP; 1.0, 2.0, 3.0, 4.0, 5.0 g kg-1) and two dicalcium phosphate particle sizes (fine orcoarse), totaling ten treatments with eight replicates of nine birds each. Egg laying rate, feed intake per bird per day, egg weight, egg mass, feed conversion ratio per egg mass and per dozen eggs, eggshell, yolk and albumen relative and absolute weights, as well as bone ash, phosphorus, calcium, and magnesium contents were evaluated. Based on the results, avP recommendations for 20-to 32-wk-old laying Japanese quails varies according with phosphate source particle size and the dietary avP levels of 4.40 g kg-1 and 3.85 g kg-1 avP levels when using fine and coarse particle dicalcium phosphate, respectively, yielded the best results.

“…Consequently, birds have higher FI to attempt to achieve normal blood P levels. However, Ribeiro et al (2016), evaluating 1.5 or 3.0 g kg -1 avP levels did not observe any feed intake inhibition or stimulation in Japanese quails.…”

“…The number of eggs and broken and soft-shelled eggs were recorded. The weekly total egg production and the percent of marketable eggs (normal eggs without cracks, misshapen and soft shells) [33] were calculated according to the formula: weekly egg production = total number of eggs during the week /12 birds; and the percent of marketable eggs = normal eggs/total number of eggs [34].…”

This study was to investigate the effects of Bacillus subtilis on production performance and bone pathophysiological characteristics of layers. Twenty-four 48-week-old Lohmann Pink-shell laying hens were randomly divided into two groups: a basic diet (control) and the basic diet mixed with Bacillus subtilis (0.5 g/kg) for a 60-day trial. Statistically, independent-sample t-test was used to assess the treatment differences. The results showed that Bacillus subtilis supplementation improved the percent of marketable eggs (p < 0.05) with reduced numbers of broken and soft-shelled eggs but had no effects on egg weight, height of albumen, yolk color, and Haugh unit (p > 0.05). Bacillus subtilis supplement also elevated maximum load (p = 0.06), maximum stress (p = 0.01), stiffness (p < 0.01), and Young’s modulus (p < 0.01) but suppressed maximum strain (p = 0.06) in the femur. In addition, compared with control birds, phosphorous concentration (p < 0.01) was reduced in serum at day 61 but increased in the femur (p < 0.05) in Bacillus subtilis fed birds. Bacillus subtilis fed birds also had lower magnesium concentrations in both femur (p = 0.04) and feces (p = 0.09). Furthermore, Bacillus subtilis increased plasma estrogen concentration (p = 0.01) and femur TNF receptor superfamily member 11b (OPG) expression (p < 0.05) but reduced plasma IL-1 (p < 0.01) and TNF-α (p < 0.01) concentrations. These results indicate that Bacillus subtilis could be used as a health promotor to reduce overproduction-induced inflammation and associated bone damage and to increase marketable egg production. The data provide evidence for developing a management strategy to use Bacillus subtilis as a feed additive to improve marketable egg production and health and welfare status of laying hens.

“…(2000) , studying laying quails, found similar results; these authors observed lower feed consumption for the higher levels of Ca and a quadratic effect for aP in which the highest consumption occurred at 0.36%, different from the present study. Other authors found no significant differences in feed intake in regard to the levels of Ca and aP studied ( Costa et al., 2007 ; Ribeiro et al., 2016 ), which proves the need for further studies to clarify the true effect of these mineral on DFI.…”

Calcium and available phosphorus requirements of Japanese quails in early egg-laying stage

et al. 2021

An experiment was conducted to estimate the nutritional requirements of calcium ( Ca ) and available phosphorus ( aP ) for Japanese quails ( Coturnix coturnix japonica ) in the egg-laying stage (64–168 D). The experiment was an entirely randomized design, in a factorial scheme (Ca = 1.70, 2.40, 3.10, and 3.80% and aP = 0.15, 0.30, 0.45, and 0.60%), with 3 replicates and 10 quails per experimental unit. No interactions were found for quail body weight and daily feed intake ( DFI ) ( P > 0.05). However, body weight decreased linearly ( P < 0.05) as the levels of Ca increased, whereas DFI exhibited a quadratic effect ( P < 0.05) for both Ca and aP. The lowest values of DFI were estimated in 2.79 and 0.36% for Ca and aP, respectively. Egg production, egg mass, and feed conversion ratio per egg dozen presented significant interaction in which all of them had a quadratic effect ( P < 0.05), with estimations for maximum yield in feed containing 2.74, 2.71, 2.75, and 2.74% Ca and 0.40, 0.39, 0.39, and 0.40% aP. The concentration of Ca in the eggshell increased linearly as per the levels of Ca studied, having a quadratic effect for aP levels, with a maximum point of 0.44%. In relation to the bone parameters, there was a linear interaction for Ca and aP in bone density and bone resistance ( BR ) of the femur, with a quadratic effect in BD estimating 2.84 and 0.50% for Ca and aP, respectively. In BR, the estimation was 3.27% Ca, with linear increase for aP. The BR of the tibiotarso increased linearly as per the Ca levels, obtaining the same Ca concentration response in this bone. As conclusion, when considering the estimations obtained through overlapped contour plots, the best responses to the effects of Ca and aP on productive characteristics were estimated at 2.68% Ca and 0.38% aP to produce feed for egg-laying Japanese quails.
