Strategy for Improving Production Performance and Quality of Layer Eggs by Giving Symbiotics (Inulin and L. Fusiformis BIP-211 isolate) Through Feeding

Symbiotic is a combination of pre-biotic and pro-biotic. This study aims to evaluate the impact of giving symbiotics through feeding on the performance and quality of layer eggs. This study used 408 Layer 65 weeks old which were divided into 2 groups as treatment. Layer maintenance was carried out for 14 days in a closed house cage with a battery cage system. The treatment in this study was giving symbiotic through feeding (0.1% of feeding) and without symbiotic as a control. The symbiotic used consisted of inulin, mineral mix, and L. Fusiformis BIP-211 bacterial isolates with a cell density of 1012. Parameters observed were production performance [(Feed Intake (FI), Hen Day Production (HDP) and Feed Conversion Ratio (FCR)], Feed digestibility [Dry matter digestibility and organic matter digestibility] and egg quality [(shell thickness, Egg Yolk Index (EYI), Haugh Units (HU), and Egg Yolk Color (EYC)]. The data obtained was analyzed using the T-Test. The results showed that giving symbiotics through feeding had a very significant effect (P-0.000) on HDP and FCR, but not significantly different on FI (P-0.900). The average FI in this study was 102 g/day. The HDP and FCR in the layer that were given the symbiote were 87.6% and 1.8 respectively, while those that without symbiotic were 81.16% and 2.02, respectively. Feed containing symbiotics had a higher level of digestibility of dry matter and organic matter compared to the control (P-0.000). The digestibility of dry matter and organic matter in this feed was 95.5 and 96.07% respectively. Symbiotic administration had a very significant effect (P-0.000) on shell thickness and had no significant effect on EYI, HU, and EYC. The conclusion of this study is that the administration of symbiotics can improve the performance and feed digestibility of layer production and increase the shell thickness without affecting egg quality.
