The aim of this study was to evaluate the feeding of Qizil fattening lambs with different levels of broiler litter (BL) on their weight gain, dry matter intake (DMI), nutrient digestibility, selected blood metabolites and husbandry economics. During an eight-weeks experimental period, 28 male lambs (an average of 42.21 ± 5.63 kg and ages of 7-8 months) were allocated randomly to one of four die...

Based on past studies of an experimental model of severe intrauterine pulmonary hypertension, we hypothesized that endothelin-1 (ET-1) contributes to high pulmonary vascular resistance (PVR), hypertensive lung structural changes, and right ventricular hypertrophy (RVH) caused by prolonged closure of the ductus arteriosus. To test this hypothesis, we studied the effects of BQ 123, a selective ET...

a total of 150 day old female chickens (ross 308) were randomly allocated to 2 groups with 5 replicate and 15 chicks in each replicate to determine the effects of cold induced ascites on performance, antioxidant status, blood enzyme activities and bone metabolism. the two experimental treatments were: 1) chicks that reared under normal temperature (nt) and 2) chicks that reared under cold tempe...

In two separate 2 x 2 factorial arrangements, 69 male, crossbred lambs were allotted randomly to the following treatments: 1) nonimplanted (NI) rams, 2) implanted (I) rams, 3) NI wethers, and 4) I wethers. In Trial 1, 36 lambs were allotted to treatment groups at birth (n = 9) and I lambs were implanted with 12 mg of zeranol between 1 and 3 d of age and again at weaning (average age of 62 d). L...

The objective of the study was to determine effect feeding ration on growth and survival Oreochromis niloticus. Three experimental hapas (T1, T2 T3) were studied for a total 8 weeks. had rectangular shape same size (0.0725 decimal). In each three conditions, 420 fish/decimal stocked. fish fed 8% their body weight in 12% T3. T1, reliant food that occurred naturally environment. T3, fishes twice ...

Essential amino acids such as methionine have been increasingly included into diets of lambs. However, few studies have determined the effects of methionine supplementation in the general performance and economic returns of lamb production. To address this question, 21weaned male Rahmani lambs were allotted to 3 dietary treatments: control diet (C), control diet plus 3.30 g of methionine/kg con...

this study was conducted to investigate the effects of l-carnitine and different levels of animal fat on performance, carcass characteristics and some blood parameters of broiler chickens. two hundred one-day old male broiler chicks were allotted to5 treatments in 4 replicates and 10 birds in each replicate. dietary treatments consisted of: 1) diet with 5% vegetable oil (t1), 2) diet with 5% ve...

INTRODUCTION Clinical application of arteriovenous (AV) extracorporeal membrane oxygenation (ECMO) requires assessment of cardiovascular ability to respond adequately to the presence of an AV shunt in the face of acute lung injury (ALI). This ability may be age dependent and vary with the experimental model. We studied cardiovascular stability in a lamb model of severe ALI, comparing convention...
