Probiotics gained significant attention for their potential to improve gut health and enhance productivity in animals, including poultry. This comprehensive study focused on the genetic analysis of Lactiplantibacillus plantarum 18 (LP18) understand its survival colonization characteristics gastrointestinal tract. LP18 was supplemented late-stage diet laying hens investigate impact growth perfor...

The present experiment was planned to ascertain the effect of dietary incorporation chili (Capsicum annuum) leaf powder on production performance and egg quality parameters Rhode Island Red laying hens 28 weeks age for a period 12 weeks. Hens were individually weighed then randomly assigned into four treatment groups with three replicates 6 birds each viz., T1: (control, containing basal diet);...

The objective of this study was to determine the ideal amino acid ratio for Japanese quail based on egg quality. In total, 120 were used. A completely randomized design used with 12 treatments and 10 replicates per treatment. consisted a balanced protein (BP) subsequent 11 diets obtained by 40% deletion BP specific test Lys, Met + Cys, Thr, Trp, Arg, Gly Ser, Val, Ile, Leu, His, Phr Tyr. trial ...

We introduce two new methods to calculate bounds for zero-sum game options using Monte Carlo simulation. These extend and generalise the duality results of Haugh–Kogan/Rogers and Jamshidian to the case where both parties of a contract have Bermudan optionality. It is shown that the Andersen–Broadie method can still be used as a generic way to obtain bounds in the extended framework, and we appl...

The influence of calcium source (limestone and oyster shell) and particle size (<0.1 mm; 0.85 to 2 mm) on laying performance, egg quality, and bone properties were examined in laying ducks by a 2 × 2 factorial arrangement of treatments. Longyan females (288) with similar BW at 24 wk of age were randomly allotted into 4 treatments, each with 6 replicates of 12 individually caged birds and studied...

This study aimed at evaluating the effect of dietary calcium levels and the replacement of calcium sources with different particle size compositions on the performance and egg quality of brown layers in their second egg production cycle. A randomized block experimental design was applied with 12 treatments in a 3x4 factorial arrangement: three calcium levels (2.6, 3.2, 3.8 %) and four combinati...

OBJECTIVE An experiment was conducted to determine the effect of superdosing phytase on productive performance and egg quality in laying hens. METHODS A total of 200 42-wk-old Hy-Line Brown laying hens were allotted into 1 of 5 dietary treatments with 5 replicates consisting of 8 hens per replicate. The positive control (PC) and negative control diets (NC) were prepared based on the recommend...
