Broiler breeder age affects carrying eggs intensity, brood eggs incubation values and chicken quality
(Journal of Food, Agriculture and Environment, 2010)
These investigations were attended to identify the influence of parental flock age at heavy hybrid Cobb 500 (usage period) on more important reproductive capabilities, respectively, on carrying eggs intensity of brood eggs, ...
Phytosociological alliances in the vegetation of arable fields in the northwestern Balkan Peninsula
(Gebruder Borntraeger, Stuttgart, 2008)
A stratified dataset of 2426 releves of weed vegetation of arable fields of the Balkan Peninsula was analysed by cluster analysis. The major division in species composition was associated with the type of crop. This accords ...
Possibilities of more efficient usage of genetic potential of broilers breeders
(African Journal of Biotechnology, 2010)
During the last ten years, poultry production in the world and particularly, EU has been specific due to new trends, whereby special attention is focused on regulations and procedures that are adopted by European Union ...
The influence of population density and duration of breeding on broiler chickens productivity and profitability
(African Journal of Biotechnology, 2010)
Fattening of broiler chickens is a very specific production process characterized by intensive production principles, rapid increase in broilers, small consumption of food/kg of gain (feed conversion ratio) and a large ...
The mode of inheritance of grain yield in two single-cross maize (zea mays l.) Hybrids
(Romanian Agricultural Research, 2011)
Efficacy of maize breeding program based on maize grain and choice of breeding method depend on effects of genes included in expression of this trait. The objective of this study was to determine genetic parameters for ...
Isolation and characterization of xanthomonas euvesicatoria bacteriophages
(Journal of Plant Pathology, 2011)
Host range, plaque morphology, thermal inactivation point, genome size and restriction fragment patterns of ten bacteriophage isolates originating from soil, pepper seed and irrigation water collected from five localities ...
Morphometric characteristics and nectar potential of Ocimum basilicum L. var. genovese (Lamiaceae) in relation to microclimatic and edaphic environmental factors
(Periodicum Biologorum, 2010)
BACKGROUND: and Purpose: Ocimum basilicum L. var genovese was grown from seed in selected soil types (eutric cambisol, fluvisol and humoglay) in order to analyse its morpho-physiological flower preference and morphometric ...
Water quality in semi-intensive carp production system using three different feeds
(Bulgarian Journal of Agricultural Science, 2010)
In the era of growing demand for sustainable usage of water, all types of aquaculture systems are under reconsideration. Until recently semi-intensive production was concerned to be one of the least polluting. Nowadays, ...
Inbred lines of different cycles of selection - donors of favourable alleles for the improvement of the kernel row number of f-1 maize hybrids
(Turkish Journal of Field Crops, 2012)
Eight maize inbred lines of different cycles of selection, originating from synthetic populations BSSS and BSCB1, were observed in the present study. The aim of the study was to evaluate inbreds and to determine which ones ...
Kinetics of Cu2+ binding to the poly(acrylic acid) hydrogel
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Isothermal kinetics of copper (ion) binding to poly(acrylic acid) (PAA) hydrogel at 20, 25, 35 and 45 C was investigated. Isothermal conversions and kinetic curves of Cu2+ binding to the PAA hydrogel were determined. It ...
