Itik (Anas plathyrynchos domecticus) merupakan salah satu jenis unggas yang banyak dibudidayakan, terutama sebagai penghasil telur. Produk telur diketahui bermanfaat dalam pemenuhan kebutuhan protein hewani bagi masyarakat di Indonesia. Permasalahan dihadapi oleh peternak itik petelur, Kabupaten Brebes adalah pakan, keterbatasan pengetahuan tentang pemeliharaan itik, permintaan asin konsumen ti...

Effects of plasticizer types and whey protein concentrate (WPC) as coatings were evaluated on internal quality shelf life eggs stored for 42 days. Eggs coated with WPC at 8 % solution combined the plasticizers glycerol (GLY), sorbitol (SOR), propylene glycol (PRO). The 20 °C. Weight loss, Haugh Unit (HU), albumen yolk pH, index (YI) weekly from day 0 to After, electron microscopy eggshell struc...

The current research work was conducted to compare the external and internal egg quality parameters of different breeds peacock. For this purpose, 130 freshly laid eggs 2 species 11 (n = 10 per breed) were obtained from captive breeding facilities. In Pavo muticus muticus, higher weight (106.57 ± 0.69), length (7.21 0.01), width (5.31 breadth (28.18 volume (100.84 0.48) recorded. However, shape...

A study was conducted to determine the effects of corn distillers’ dried grain (CDDG) on the performance and egg quality of laying hens. The hens were fed dietary inclusions of CDDG at 0, 10, 20, 30 and 40% for a period of eight weeks. Average feed intake, weight gain, feed conversion ratio and nitrogen economy varied significantly (P<0.05) among dietary treatments. Birds fed 30% dietary CDDG h...

An experiment with laying hens and broiler breeders of two ages (young 22 vs. 36 weeks, old 83 vs. 64 weeks) and at temperatures of 20 and 28°C was carried out to evaluate the interactions between oviposition time (7:30; 11:30, and 15:30 h), age, and temperature on the one hand and egg quality on the other. A significant interaction (P ≤ 0.011) was determined in oviposition time. The highest nu...

This study was carried out to determine the effect of pre-incubation storage periods on egg weight loss, embryonic development and hatchability of hatching pullet eggs. Three hundred eggs were used for this experiment. The eggs were sourced on five different days (sixty eggs per day) at three days interval (day 0, 3, 6, 9, and 12) and weighed. The sixty (60) eggs collected on each day were subd...

The objective of this study was to investigate the effects of dietary corticosterone on egg quality. For 2 weeks hens received either control or experimental diet containing corticosterone at 30 mg/kg diet. Feed intake and egg production were monitored daily, and body weight measured weekly. Egg weights and egg quality were measured daily. Corticosterone treatment resulted in a remarkable incre...

In the present study, 256 7-wk-old Japanese quail were randomly distributed into four experimental groups (64 birds per group) and given rations containing 0 (controls), 25, 50, or 100 (g aflatoxin B, (AFB1)/kg feed for 168 d. Each treatment consisted of four replicates of 16 quail. Egg production and individual egg weight were checked daily. Feed consumption and feed use were determined weekly...

This paper proposes an easy test for independence between two stationary autoregressive fractionally integrated moving average (ARFIMA) processes via AR approximations. We prove that an ARFIMA (p, d, q) process, φ(L)(1 − L)yt = θ(L)et, d ∈ (0, 0.5), where et is a white noise, can be approximated well by an autoregressive (AR) model and establish the theoretical foundation of Haugh’s (1976) stat...
