An experiment was conducted in order to study the possibility of compensatory growth by changing dietary nutrients concentration in the female Arian broiler chicks using a completely randomized design by means of standard and diluted diets. By standard diet is meant diet recommended by Arian’s guide catalogue and by diluted diet is meant the diet used in Iran broiler farms. However, both diets ...
this experiment was conducted to determine the ame, amen, tme and tmen of beet pulp fed to male ostriches at their 90 d of age. different levels of beet pulp (0, 15, 30 and 40%) were fed through replacements in the basal diet. for a determination of ame and amen using marker method, beet pulp was replaced in the basal diet at 40%. a number of 16 vs. 8 ostrich chicks were employed in each of th...
Scientific knowledge of ostrich diseases is incomplete and very fragmented, with specific details on technical aspects of diagnostic and/or screening tests completely absent in most cases. Salmonella Typhimurium is common in multispecies collections and causes mortality in chicks younger than three months on commercial farms, but is rarely found in chicks older than six months, or slaughter bir...
این مطالعه به منظور تعیین اثر زمان برداشت 40 و 60 روزگی (به ترتیب مراحل گلدهی و شیری-خمیری شدن دانه ها) و سطوح کود نیتروژنی (120، 180 و 240 کیلوگرم نیتروژن خالص در هکتار) بر ارزش غذایی علوفه تاج خروس (amaranthus hypochondriacus) با استفاده از آزمایشهای فاکتوریل در قالب طرح بلوکهای کامل تصادفی انجام شد. بدین منظور، مقادیر ماده خشک (dm)، پروتئین خام (cp)، پروتئین حقیقی (tp)، عصاره اتری (ee)، کربو...
BACKGROUND Ostrich (Struthio camelus) breeds have been gaining increasing significance around the world. The large-scale sex determination of chicks is an important task in the development of these breeds. To date, two PCR-based methods have been established for ostrich sex typing, neither of them intended for large-scale analyses. Here, we report on a protocol adapted to carry out large-scale ...
Eight hundred and fifty two multiparous Holstein cows in mid-lactation were used in a completely randomized and nested design with two treatments and three replications. Treatments were: 1) Isfahan and 2) Borkhar-Meymeh. Replications were: 1) class of one to five cows 2) class of six to ten cows and 3) class of eleven to twenty cows. Paired t-test was used for the comparison of nutrient consump...
