This paper proposes a procedure for transfer function identification (specification) based on least-squares estimates of transfer function weights using the original or filtered series. The corner method is then used to identify a parsimonious rational form of the transfer function. The procedure is illustrated in a simulated example; it is shown how this straightforward approach outperforms ot...

ABSTRACT The aim of this study is to evaluate the influence including levels calcareous seaweed flour in replacement for calcite limestone on diet under egg conservation at different storage periods. 140 Japanese quails were used a completely randomized experiment consisting 4x4 factorial design. design was four inclusions (0%, 10%, 20%, and 30%) periods (zero, seven, 14, 21 days) with ten repl...

The effect of supplementing natural zeolite (NZ) on the laying characteristics and internal external egg quality during period Japanese quails was studied. average eggs per female were lower in control (C) Z1 experimental groups (1% NZ) compare with Z2 group (2% NZ). significant NZ addition comparison C found eggshell weight yolk index. (1.10±0.01 g) significantly than (1.18±0.01 g). had Z1. af...

Currently, the egg industry is experiencing a shift in demand for eggs from cage-free environments. This study aims to evaluate quality parameters of white laid several different housing environments utilized industry. Egg battery cages, barren colony enriched cages and pens were compared. Overall, most found be across Battery produced heaviest with highest Haugh unit (p < 0.05). Cage-free h...

This meta-analysis aimed to evaluate the effects of dietary supplementation with essential oils (EOs) on egg production and quality, antioxidant status in blood serum, intestinal morphology laying hens. The data used were obtained from 38 peer-reviewed publications. effect size was evaluated by weighted mean differences (WMD) between experimental treatments (diets added EOs) control without EOs...

Eggs are foods with almost perfect proteins, while also containing nutrients high biological value. The purpose of this study was to evaluate the morphological structure, physical-chemical, nutritional, and microbiological parameters commercial free-range eggs sold in municipality Santarém, State Pará, Brazil. two types were compared check for any differences quality. evaluations conducted on v...

Our previous studies demonstrated that low-grade tea had some beneficial effects on egg production performance and quality. Extracts derived from high levels of active ingredients. Thus, this study investigated the green water extracts (GTWE) supplementation production, quality nutritional value laying hens. A total 192 hens were randomly allotted to four groups T0, T1, T2 T3, which fed with ba...
