one hundred forty-four 26-wk-old white hy-line layers (w-36) were fed commercial diets containing 0, 1.5, 3 and 5% surplus date for three period of 28 days each to study the effects of dietary surplus date on hen performance (egg production, egg weight, egg mass, feed intake, feed conversion ratio ‘fcr’ and body weight gain) and egg quality parameters (haugh unit score, yolk colour index, yolk ...

the present study was carried out to investigate the effect of corn replacement by different levels of wheat with supplementation of phytase with reduced phosphorus level for laying hens. two hundred seventy nine layer hens (the strains of hy-line w36) at the 53th week of age, selected based on the same egg production percentage and body weight, assigned in a factorial arrangement with complete...

This work aimed to study the effect of two different levels of ration energy supplemented with Alpinia officinarum. Rabbits were classified into six equal groups (G1-G6). The 1 and 4 groups received basal ration with 100 % and 90 % energy requirement and served as first and second control respectively. The 2 and the 3 groups received basal ration with 100 % energy requirement supplemented with ...

— The following new species of Cochliopinae (Prosobranchia: Hydrobiidae) are described: Aroapyrgus polius from Mexico; Cochliopa perforata from Costa Rica; Heleobops clytus from the Dominican Republic; H. torquatus from Jamaica; Lithococcus aletes from Costa Rica; and Littoridina microcona from Costa Rica. In addition, the following new genera and species are described: Mesobia pristina from Ho...

Understanding variation in SW (seed weigh) is of major importance in understanding SY (seed yield) variation. The objective of this study was to determine factors such as SN (seed number) per unit area, SFD (seed filling duration) and SFR (seed filling rate) and temperature, LAI (leaf area index), LAD (leaf area duration), above-ground dry matter, CGR (crop growth rate), leaf dry matter re...

The genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. The results revealed that the single shell weight showed higher genetic variation such as PCV% (17.20%), GCV% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. The D2 (Mahalonobis? distance) statistics reveal...

The existence and role of an L-arginine:nitric oxide (NO) pathway in two human colorectal adenocarcinoma cell lines, SW-480 and SW-620, were investigated. Both cell lines, which derive from the same patient, SW-480 from the primary tumor and SW-620 from its metastatic lesion, were shown to have a cytosolic, Ca(2+)-independent, NADPH-dependent NO synthase, the activity of which was lower in the ...

Researchers are currently developing new value-added uses for almond shells, an abundant agricultural by-product. Almond varieties are distinguished by processors as being either hard or soft shelled, but these two broad classes of almond also exhibit varietal diversity in shell morphology and physical characters. By defining more precisely the physical and chemical characteristics of almond sh...

abstract almond is an important nut tree which is cultivated in many mediterranean countries. this study was carried out to study some vegetative and reproductive traits as well as qualitative and quantitative characteristics and their correlation in some self-compatible and self-incompatible genotypes obtained from crossing between touno (male parent) and shahrood 12 (female parent). quantitat...
