ارزیابی اثر بهبود بخش روغن سیاه دانه بر بافت بیضه موش های تیمار شده با بیس فنول آ.مطالعه استریولوژیک
هدف : بیس فنول آ یک آلاینده زیست محیطی با اثرات استروژنیک است که موجب استرس اکسیداتیو در بافت بیضه می شود. هدف از این مطالعه بررسی اثر حفاظتی روغن سیاه دانه به عنوان یک آنتی اکسیدان بر بافت بیضه موش های تیمار شده با بیس فنول آ بود . مواد و روش ها : در این مطالعه 24 سر موش نر بالغ (nmri) به چهار گروه (6=n) : کنترل ، بیس فنول آ (mg/kg/day 200) ، روغن سیاه دانه (ml/kg/day 5) و بیس فنول آ + روغن ...
forty growing ram lambs (lori-bakhtiari breed) averaging 28 kg (±1.5) were allocated in this study to evaluate the optimal dietary energy density in a lamb fattening enterprise in iran. the feed intake (fi), body weight (bw), gain to feed ratio (g:f) and carcass characteristics were studied. four treatments differed in metabolizable energy content (me) as follow; 2, 2.3, 2.6 and 2.9 mcal/kg for...
The experiment was conducted on 80 Polish Merino ewes, their 82 lambs and 40 fattening rams. Merino ewes were divided into two groups: experimental (E) and control (C), each composed of 40 animals. Four weeks before lambing, 1 day, 3 weeks and 6 weeks after lambing 40 ewes of the experimental (E) group received intramuscular injection of 5 ml 0.1 % Na2SeO4 (selenium [Se]: 2.09 mg), 10 ml 10 % Z...
in this research, effects of adding methafix (containing malate and fumarate as organic acids) with or without monensin in diet of fattening farahani lamb's on performance, and plasma concentration of some metabolites and minerals were investigated. twenty-four male lambs (4-6 months old, 35.9 ±7.4 kg) were randomly assigned to; 1) control diet (control), 2) control with 24 mg of monensin...
The effect of dietary supplementation with organic selenium and vitamin E on chemical characteristics and fatty acid composition of goose meat (breast and leg muscles) and liver is described. Twohundred one-day-old White Koluda® goslings were randomly divided into two groups balanced by sex, with five replicates each. Up to week 13 of age the control group was fed basic feeds, while the experim...
BACKGROUND Facilities for fattening pigs offer limited possibilities for exploration and wet feeding systems, where the pigs drink the food instead of eating it, have expanded on behalf of dry feeding systems. As little has been made to evaluate liquid feeding from the point of view of the pigs, the aims of this study were to compare behaviour in general and behaviour at feeding in particular o...
Three diets with varying amino acid levels were fed in two nitrogen balance studies and two fattening experiments in order to determine the nitrogen retention and growth performance of boars of different sire lines. A total of 12 boars, 6 crossbreed boars sired by Piétrain boars (Study 1) and 6 crossbreed boars sired by Duroc boars (Study 2) were used in the nitrogen balance studies. The feedin...
Case presentation: This report presents a case of trichurosis diagnosed in a farrow-to-finish Belgian pig herd. The infection was associated with severe and persistent diarrhoea, growth retardation, emaciation and/or anaemia in 10 recently purchased gilts and in fattening pigs. In gilts, levamisole [8 mg (kg body weight)] administered once per os gave a good clinical response, as diarrhoea reso...
increased feeding frequency improve bioenergetics efficiency in lactating cows; however, there is little information about its effect on fattening animals.twelve holstein bull calves were allotted to two groups to determine the effect of feeding frequency on body weight, carcass quality and hormonal profiles. control group was fed twice a day and treated group was fed six times a day by a stand...
Forty growing ram lambs (Lori-Bakhtiari breed) averaging 28 kg (±1.5) were allocated in this study to evaluate the optimal dietary energy density in a lamb fattening enterprise in Iran. The feed intake (FI), body weight (BW), gain to feed ratio (G:F) and carcass characteristics were studied. Four treatments differed in metabolizable energy content (ME) as follow; 2, 2.3, 2.6 and 2.9 Mcal/kg for...
