[ 1 ] - Performance, growth status, rumen fermentation and some blood metabolites in blood of Holstein bull calves fed starch or fermented fiber based diets
Starch (SS) and fermented fiber (FFS), as energy sources were included in Holstein bull calf diets to evaluate their growth performance, rumen fermentation pattern and concentration of insulin and selected blood metabolites. Fourteen Holstein bull calves (BW=94.5±2.1 kg; age 87±9 d) were allocated to treatments (n=7 calves per treatment) and the study lasted 10 weeks. The diets were based on ba...
[ 2 ] - تولید و ارزیابی مکملهای ریزپوشانی شده روغن ماهی در شرایط برون تنی (آزمایشگاهی): ارزش تغذیهای و مقاومت در برابر زیست هیدروژندارشدن شکمبهای در مقایسه با مکملهای کلسیمی
هدف از این پژوهش، تولید و ارزیابی مکملهای جامد روغن ماهی با استفاده از روش تولید نمکهای کلسیمی و ریزکپسوله نمودن با استفاده از سیستم خشککن پاششی بود. دو نوع ماده پوشاننده به همراه سطوح مختلف روغن ماهی در ساخت ریزکپسولها مورد استفاده قرار گرفتند. میزان انواع مواد مغذی و الگوی اسیدهای چرب، میزان پوشانندگی مواد دیوارهای مختلف و ارزیابی کیفیت تغذیهای ریزکپسولها بر اساس سیستم پروتئین و کربوهی...
[ 3 ] - The potential of sunflower (Helianthus annuus) residue silage as a forage source in Mohabadi dairy goats
This study was conducted to determine the chemical composition and nutritive value of sunflower residues silage (SRS) and effects of its substitution with alfalfa hay and corn silage on lactation performance, feed intake, nutrient digestibility and some blood parameters of Mohabadi dairy goats. Four experimental diets were formulated to gradually replace alfalfa hay and corn silage with SRS as ...
[ 4 ] - Microwave irradiation of whole soybeans in ruminant nutrition: Protein and carbohydrate metabolism in vitro and in situ
Whole soybeans serve as one of the main sources of protein in ruminant nutrition. Different processing methods have been employed for ruminal protein protection. The present study was conducted to determine the effects of microwave irradiation [900 W; 2, 4 and 6 min] on quality, ruminal degradability and estimated in vitro intestinal digestibility of availability soybean crude protein....
[ 5 ] - Investigating the effects of varying wall materials and oil loading levels on stability and nutritional values of spray dried fish oil
High oxidative capacity of polyunsaturated fatty acid rich oils is the main problem with their dietary application. The main objectives of this study were to determine the effects of different encapsulants and oil loading levels on nutritive value, fatty acid profile, and oxidative stability of microencapsulated fish oil powders. Four types of wall materials [glucose syrup and maltodextrin base...
