Abstract
The ability of chickens to retain calcium at high temperatures is low, so a lot of calcium is wasted through feces. As a result, the adequacy of minerals to support growth, bone strength and egg production is reduced. The aim of this study was to examine the effect of different calcium sources on Arabic hens during the early egg-laying period. This study used 30-week-old Arabic hens in cages with a semi-scavenging system and were given the opportunity to choose calcium from limestone and oyster. As a control (T1), chickens were only given a ration with calcium and phosphorus were based on feed standards from Hy-line International in 2018. Other treatment feeds were control feeds without lime fed with a combination of limestone (T2) or oyster (T3) separately. The data collected were feed consumption, calcium consumption, calcium concentration and egg production. This study used a completely randomized design. The results showed that the treatment had no significant effect (P<0.05) on feed consumption (g/bird/week) and egg production (%) but had a significant (P<0.05) effect on calcium consumption (g/ bird /week) and calcium concentration (%). Calcium consumption and concentration were the same at T1 and T3, and both were higher than T2. It can be concluded that Arabic chickens are able to consume calcium according to their needs during the early laying period and the calcium requirements is lower (3.15%) than the current calcium recommendation in the control diet (4.2%), especially when limestone as source of Ca due to produce the same percentage of egg production.
