This experiment was designed to evaluate the effects of different sources of calcium at different rates and cholecalciferol(Vitamin D3) on the performance and egg quality of Hy-line W-36 Laying hens. In this study a total of 648 hens were managed in a completely randomized design using a factorial arrangement of 3 × 3 × 2 treatments, with three calcium sources (oyster shell, OS; ground limeston...

This study investigated the impact of different levels dietary energy and crude protein on productive performance, egg quality, reproductive parameters in Rajasri breeder birds during a 12-week period between 25 to 36 weeks age. A total 648 were divided into nine treatments, each with eight replicates, following 3 × factorial arrangement three metabolizable (2400, 2500, 2600 kcal ME/kg) (14, 15...

The TA-XT21 texture analyzer (TA) was used to evaluate vitelline membrane strength (VMS). Fresh and aged (1 wk at 25 C) eggs (n = 48 eggs x 2 replications) were evaluated. Fresh and aged eggs were further divided into two groups of yolk only or whole egg (with intact albumen). Yolk index, Haugh units, pH, broken-out egg weights, VMS, yolk viscosity, and scanning electron microscopy (SEM) images...

Abstrak. Ayam ALOBRA merupakan hasil persilangan antara ayam lokal dengan brahma yang dikembangkan di Laboratorium Lapangan Peternakan (LLP) Fakultas Pertanian Universitas Syiah Kuala. Rendahnya produktivitas serta kualitas DOC dihasilkan masih belum optimal menjadi permasalahan utama dalam pemeliharaan ALOBRA, sehingga perlu adanya upaya untuk meningkatkan performa reproduksi dan menunjang pot...

the correlation between serum steroid hormones, testosterone (t), 17β-estradiol (e2), and progesterone (p) and weight of female fishes, biological characteristics of gonad (e.g. fertilization rate, fluid egg rate, gonadosomatic index , polarization index and oocyte diameter) in 10 female of the migratory population of sterlet (acipenser ruthenus) and 5 female of the migratory population of sibe...

Abstract Present study was planned to determine variations in external and internal quality egg parameters of different avian species including ostrich Struthio camelus, ducks Anas platyrhynchos, chicken Gallus gallus, turkeys Meleagris gallopavo grey francolin Francolinus pondicerinus. All the birds were kept under similar rearing conditions. A total 150 eggs collected for each record features...

We present a scheme for constructing various Conley indices for locally deened maps. In particular we extend the shape index of Robbin and Salamon to the case of a locally deened map in a locally compact Hausdorr space. We compare the shape index with the cohomological Conley index for maps. We also prove the commutativity property of the Conley index, which is analogous to the commutativity pr...

This research aimed to compare the effects of pigments extracted from dried petal meal of marigold flower and synthetic pigments on productive performance of laying hens, egg quality and antioxidant properties of the egg. A total of 64 laying hens, aged 75 weeks, were distributed in a completely randomized design in 4 treatments and 4 replications containing 4 hens per cages. Experimental group...
