A 3 x 3 treatment arrangement varying in dietary protein and TSAA:Lys was used to evaluate the effect of low-protein diets fed to Hy-Line W-98 laying hens. Phase I was 20 to 43 wk of age with 18.9, 17.0, and 14.4 g of protein/hen per day and 0.97, 0.85, and 0.82 TSAA:Lys, whereas phase II was 44 to 63 wk of age with 16.3, 14.6, and 13.8 g of protein/hen per day and 0.92, 0.82, and 0.72 TSAA:Lys...

A study to determine the protein digestibility-corrected amino acid score and protein efficiency ratio of nine different cooked Canadian pulse classes was conducted in support of the establishment of protein quality claims in Canada and the United States. Split green and yellow pea, whole green lentil, split red lentil, Kabuli chickpea, navy bean, pinto bean, light red kidney bean, and black be...

To study the physiological and morphological relationships of two clover species affected by herbicides, Pursuit experiment in a factorial based on randomized completely design with 3 replications at the Damavand in 2012. The first factor consisted of two species of Trifolium pretense L. and Trifolium alexandrinum L. and the second factor consisted of three levels of herbicide...

variation in growth, feed utilization and survival was assessed in sturgeon fingerlings of beluga fed different dietary lipid levels. all diets were iso-nitrogenous (protein = 45%) comprising 3.4-3.7 kcal digestible energy g-1. triplicate groups of 35 fingerling beluga with a mean initial wet weight of 2.14 ± 0.07 g (± sd) were fed with four experimental diets containing 6.7, 10.5, 14 and 17% c...

This experiment was conducted to evaluate the efficacy of different levels of Echinacea (Echinacea purpurea) methanol extract on the growth performances (final weight (FW), daily growth ratio (DGR), feed conversion rate (FCR), voluntary feed intake (VFI) and protein efficiency ratio (PER) and some of hematological parameters (hemoglobin (Hb), hematocrit (Hct), red blood cell (RBC) and white blo...

introduction sunflower (helianthus annuus l.) is one of the most important oil crops in the world. iran is climatically regarded as an arid and semi-arid region in the world, where the lack of precipitation and its inappropriate distribution, high temperature and extensive evaporation makes the irrigation the main way for meeting plants water demand. hence, studying the effect of irrigation on ...

A feeding trial was performed to investigate inclusion levels of distillers dried grains with solubles (DDGS) as a fishmeal replacement for juvenile Nile tilapia (Oreochromis niloticus). On a dry matter basis, five isocaloric [19.3 ± 0.4 kJ/g (mean ± SE)], isonitrogenous (39.1 ± 0.5% crude protein) diets were formulated to contain 17.5%, 20%, 22.5%, 25%, and 27.5% DDGS and compared against a 0%...
