the present work aimed at studying growth pattern and carcass traits in pearl grey guinea fowl fed on dietary neem (azadirachta indica) leaf powder (nlp) over a period of 12 weeks. day old guinea fowl keets (n=120) were randomly assigned to four treatment groups, each with 3 replicates. the first treatment was designated as control (t0) in which no supplement was added to the feed, while in tre...
Understanding the functional linkages between the pelagic and demersal stages of marine organisms is a central goal in ecology. To better understand events that occurred during the larval period as well as their initial influence on juvenile traits, we examined individual level variation in early life-history traits (larval and early juvenile otolith growth rates, size-at-age, and larval durati...
Sowing a second season crop following the harvest of first (hereafter referred to as double cropping) is practice that allows for temporal diversification cropping systems increase efficiency land use and yield per unit area while improving ecosystem services. Sunflower particularly suitable cropping, especially under current context Southern Europe. However, planting sunflower in may result po...
For benthic marine organisms with complex life cycles, conditions experienced by pelagic larvae can influence juvenile survival. Trait-specific selective mortality has been documented in the laboratory and field, yet our knowledge of the factors contributing to the existence, strength, and consistency of natural selective mortality is limited. We compiled previously published and unpublished da...
Background: As Moringa peregrina is a valuable medicinal plant in traditional medicine, it is necessary to determine responses of this plant to salinity. Objective: To determine some biochemical and growth responses of Moringa peregrina to salinity at the seedling stage. Methods: This experiment was conducted in Institute of Medicinal Plants-ACECR, on base of factorial experiment as ...
The data were collected from 1992 to 2009 in Burri, White Boni and Black Boni sheep maintained at the Regional Research Station in the Central Highlands of Yemen. Data were analyzed to study the effects of environmental and genetic factors on body weight and growth rate from birth to weaning. The least square means for body weights (BW) were 2.54, 2.18 and 2.26 kg for birth; 12.49, 10.58 and 11...
the ovine melatonin receptor 1a (mtnr1a) and aromatase (cyp19) genes were structurally characterized and the association between their variants and reproductive and growth traits was studied in kurdi sheep at kurdi sheep breeding station located in shirvan, iran. the genomic dna was extracted by guanidine thiocyanate-silica gel method. polymerase chain reaction was carried out to amplify 824 bp...
The pattern of genetic variation in shoot growth of Turkish red pine (Pinus brutia TEN.) was studied in 180 open-pollinated families from a south to north transect in southern Turkey. Seedlings from 1 coastal, 1 inland and 2 centrally located populations (45 open-pollinated families each) were grown for 2 growing seasons in a forest nursery located near Antalya. The study revealed that both pop...
the genetic parameters and (co) variance components of body weight at birth (bw), weaning (ww) and six months of age (bw6) and average daily gain (adg) pre and post-weaning of afshari sheep were estimated using restricted maximum likelihood (reml) methodology and animal model implemented in dfreml software. the likelihood ratio test (lrt) was used to compare the models. year of birth, age of mo...
genetic parameters for birth weight (bw), weaning weight (ww), 6 months weight (6mw), 9 months weight (9mw) and yearling weight (yw) in baluchi sheep were estimated using data collected during a 26-year period (1984-2010). estimates of (co)variance components were obtained by reml procedures by fitting a linear mixed animal model. significant random effects for each trait were explored by fitti...
