“…This finding can be attributed to the similar content of calcium and phosphorus in each treatment diet. According to Ahmed et al (2013), calcium is one of the nutrients that influence the eggshell quality and production of laying hens. Eggshell strength of laying hens fed 2.62% calcium in the diet was more weakness than that of laying hens fed diet containing 3.70 to 4.4% calcium (Jiang et al, 2013).…”

This study was performed to evaluate the effect of inclusion of boiled tomato waste powder in laying hens diet on growth performances and egg quality. Tomato waste used in this experiment was surplus and unsold mature tomato from the last harvest on the field. The tomato waste was boiled in boiling water (100 ºC) for 8 minutes to convert their lycopene structure from trans to cis, which is easily absorbed by the poultry digestive tract. In a completely randomized design, 200 Isa Brown laying hens were divided into five groups with different inclusion levels of boiled tomato waste powder (0, 3, 6, 9 and 12%) in an iso-nitrogenous (16%) and iso-caloric (2600 kcal/kg) diet. Daily feed intake, hen day egg production, egg weight, egg mass, feed conversion ratio, eggshell thickness, and eggshell strength were measured. The obtained results showed that boiled tomato waste powder in the diet did not significantly affect daily feed intake, feed conversion ratio, egg production and egg quality. In conclusion, the tomato boiled powder could be used up to 12% in laying hens diet with no effect on performance and egg quality of laying hens.

“…Ca is the most prevalent mineral in the bird’s body [ 17 ] and the most critical factor to ensure the proper calcification of the eggshell, since up to 96% of the dry mass of an eggshell consists of calcium carbonate [ 18 ]. Moreover, Ca plays an important role in regulating the reproductive hormones and ovary growth [ 19 ].…”

The objective of this study was to evaluate hen performance and eggshell quality response to genotype, housing system, and feed calcium (Ca) level. For this purpose, an experiment was conducted on 360 laying hens of ISA Brown, Bovans Brown (commercial hybrids), and Moravia BSL (traditional Czech hybrid). Laying hens were kept in enriched cages and on littered floor and fed similar feed mixtures with different Ca content (3.00% vs. 3.50%). In terms of hen performance, ISA Brown had the highest egg production (84.2%) compared to Moravia BSL (74.3%) and Bovans Brown (71.4%). Regarding eggshell quality, Bovans Brown showed the highest values of all eggshell quality parameters. Increasing feed Ca level augmented egg production (p ≤ 0.001) but had no effect on other performance parameters. Except eggshell thickness, all eggshell quality parameters were affected by the three-way interaction of genotype, housing, and Ca. Bovans Brown, which had the strongest eggshells (5089 g/cm2) when housed on a littered floor system and fed 3.00% Ca, while Moravia BSL housed on a littered floor had the weakest eggshells (4236 g/cm2) at 3.50% Ca. The study pointed out the importance of the interactions between studied factors on performance and eggshell quality compared to an individual factor effect.

“…Narvaez-Solarte et al (2006), Safaa et al (2008) and El-Maksoud (2010) indicated an improvement of egg production with increasing dietary Ca levels. Additionally, an increasing dietary Ca level increased the egg production of laying pigeons (Chang et al 2019) while the study of Pelicia et al (2011) concluded a significant linear reduction of https://doi.org/10.17221/228/2019-CJAS egg production as dietary Ca levels were increased. Layers fed diets with 4.50% Ca presented lower egg production than those fed 3.00% and 3.75% Ca.…”

“…However, An et al (2016) found no significant effect of Ca levels on the Haugh unit. Chang et al (2019) reported a significant effect of different dietary Ca levels (0.60, 0.90, 1.20, 1.80, 2.40, and 3.00%) on the egg quality of pigeon eggs. They indicated that albumen percentage, albumen height and Haugh unit were all linearly increased by rising dietary Ca.…”

“…However, An et al (2016) and Tumova et al (2016) reported no significant effect of dietary Ca levels on egg production. Kermanshahi andHabavi (2006), Pelicia et al (2011) and Chang et al (2019) stated that dietary Ca levels did not significantly affect the feed consumption. These different findings might be related to different experimental factors which affected the final outputs.…”

The present study aimed to evaluate the effect of two dietary Ca levels (3.00% vs 3.50%) in three hen genotypes (ISA Brown, Bovans Brown and Moravia BSL) on their laying performance and quality of their eggs. In order to evaluate the response to dietary Ca, an experiment was conducted with 300 laying hens. One hundred birds from each genotype were divided into 10 replicates (10 birds/cage/Ca level). To reveal the differences, the following characteristics were measured: hen-day egg production percentage, daily feed intake, egg weight, albumen and yolk weights, Haugh unit, eggshell colour, eggshell weight, eggshell thickness, eggshell strength, egg shape index and eggshell index. A higher Ca level significantly increased the hen-day egg production percentage of Bovans Brown and Moravia BSL, while ISA Brown laying hens had the higher egg production percentage at a lower dietary Ca level (85.97% vs 82.41%). No significant effect of dietary Ca level was observed on any internal egg quality measurements except the Haugh unit. However, the dietary Ca level significantly affected some of external egg quality measurements, namely eggshell colour (P < 0.001), eggshell weight (P = 0.003) and eggshell strength (P = 0.012). The results of the present study show that laying performance and egg quality parameters responded differently according to hen genotype and dietary Ca level. Bovans Brown and Moravia BSL laying hens required higher levels of Ca to keep egg production high, while the eggshell quality measurements were better at the lower dietary Ca level. Thus, it is recommended to adjust the Ca levels in feed to the nutritional requirements of laying hens.
