“…At a lower level of LG supplementation the effects were not statistically significant. This finding confirms in part previous reports on the effect of limestone and oyster shell particle size on laying performance (Roland and Harms, 1973;Roland, 1986;Guinotte and Nys, 1991), and on feed intake and egg mass data reported by Vogt (1983).…”

“…The highest values were found at 40-60%) LG replacement, when hens received diets containing limestone grit at levels of 3.24-4.86 g"100g _1 . These results are generally consistent with numerous reports confirming a positive effect of coarse particle sized limestone on eggshell quality (Scott et al, 1971;Guinotte and Nys, 1991;Richter et al, 1999), mainly in the summer (Roland and Harms, 1973), but are inconsistent with other results reported in the review by Roland (1986). The inconsistencies in the positive effect of limestone may depend not only on particle size but also on the lighting schedules used, especially the duration of the dark period.…”

“…The solubility of finely ground limestone has no effect on calcium utilization (Cheng and Coon, 1990;Richter et al, 1999). Particle-sized calcium sources persist in the gizzard and tend to cover calcium requirements of hens better than pulverized sources (Scott et al, 1971;Roland and Harms, 1973;Guinotte and Nys, 1991;Richter et al, 1999). The slower dissolution of grit forms may make calcium available during the night, when there is no feed intake but calcification of eggshells is proceeding (Roland and Harms, 1973).…”

Limestone was crumbled into fine particles (LF) of 0.1-0.4 mm or to a particulate grit (LG) of 2-4 mm. One hundred and eighty individually kept Hy-Line Brown laying hens were used in the experiment and divided into 10 groups. Diets containing 8.1% of LF or LG substituted for LF at a proportion of 10, 20, 40, 50, 60, 80 and 100% were compared with diet containing 8.1% oyster shells.At moderate substitution levels, the particulate limestone grit increased the thickness of eggshells in the first laying period (60-80% LG), improved yolk pigmentation (20-100% LG) and enlarged calcium deposition in eggshells (10-100%) LG). Partial (20-90%) and complete substitution of LG for LF increased eggshell breaking strength, but improvement of tibia bone strength was observed only at 20% LG limestone. Analysis of feed refusals suggests that the limit value of voluntary intake of grit particles LG is 5.5 g daily per hen.

This study evaluated the effect of dietary calcium levels and limestone particle size distribution on first-cycle layer performance and egg quality. A completely randomized experimental design in 4x3 factorial arrangement (four Ca levels -3.0, 3.5, 4.0, 4.5%; and three limestone particle size distributions -100% fine, 50% fine and 50% coarse, 30% fine and 70% coarse) was applied, totaling 12 treatments with six replicates of eight birds each. The treatments did not influence the most of evaluated performance and internal and external egg quality parameters. However, limestone particle size distribution quadratically affected with percentage of defective eggs, with the lowest percentage obtained with the distribution 61.75% fine limestone and 38.25% coarse limestone. Increasing dietary Ca levels significantly increased eggshell weight per surface area and the percentage of Ca excreted in the feces. It was concluded that the combination of the highest dietary Ca level (4.5%) with 50% replacement of fine-particle limestone by coarse limestone results in better eggshell and increases the number of marketable eggs.
