The current study aimed to evaluate effects of four levels (0, 2, 4 and 6 % of diet) of soybean lecithin in the isoproteic and isoenergitic (50% protein and 18.5 kj/g) diets on growth performance, feed utilization and hematological parameters of juvenile sobaity seabream (Sparidentex hasta) with initial weight of 37.9±0.16 g. At the end of 56 days of feeding trial, results showed that growth pe...
the current study was conducted to investigate the effect of short-term divergent selection on the shape growth curve in different lines of japanese quail. the quail lines utilized in this study were two divergently selected for high (hw) and low (lw) 4-wk body weight during 7 generation and also a control line (c). the richard function parameters were used to describe growth curves of differen...
In this study, it is explained how the Richards model, which one of sigmoid growth models, transformed into a mechanical model with biologically significant parameters such as maximum value, lag time and specific rate. Detail transformations containing 4 calculated help first second derivatives were given. order to test accuracy prediction values analyzed by using height data E. Camaldulensis D...
The aim of this study was to investigate the effects of extruded flaxseed and conjugated linoleic acid on growth performance, blood parameters in Holstein suckling calves. This experiment was carried out with 30 newborn Holstein calves with an average age of 1-8 days, and about 36±2 kg body weight, with 6 treatments and 5 replications in a completely randomized factorial design (3×2). The treat...
staphylococcus aureus is one of the most prevalent causes of gastroenteritis worldwide. knowing the precise boundary for the growth/no growth interface of s. aureus and also determining the period of time needed for bacterial growth initiation is necessary for food safety risk assessment. this study was designed to examine the combined effects of temperature, acetic acid, inoculum level and nac...
The purpose of this study was to evaluate Y shape appliance for expansion on maxillary arch of patients in their mixed dentition age. Eight patients, 6 girls and 2 boys, with maxillary constriction, retrusion of maxillary anteriors, and space deficiency of upper canine were treated by Y-plate expansion. For each patient 8 parameters on upper cast and 7 parameters on lower cast were measured. St...
