All organisms are probably exposed to different types of electromagnetic fields (EMFs). This study is an attempt to evaluate the effect of extremely low-frequency EMFs (50 Hz) on some growth parameters and survival rate of common carp fingerling. The fry (n = 120, averaged 16.76 ± 0.88 g in initial weight) was exposed to ELF-EMF at four intensities of 0.1, 0.5, 1 and 2 mT only once for 2 h and ...

background: the timing of maternal weight change in pregnancy may be an important determinant of birth weight. the objective of this study was to measure weight gain patterns from early pregnancy until delivery, and to examine the relationship between prenatal weight gain and low birth weight.   methods: a total of 500 pregnant women within 15-20 days of conception, with confirmed pregnancies a...

This study was conducted to determine the effects of dietary supplementation of peppermint ( Mentha piperita L.) on the performance of broiler chicks. 500 Ross broiler chicks were divided into 5 treatment groups of 4 replications in a completely randomized design format. The diets were ISO-caloric and ISO-nitrogenous ones and contained 1.5, 3, 4.5, and 6 g/kg of peppermint powder. At start, gro...

In 40 Polish Landrace, 38 Polish Large White and 14 Pietrain fatteners the longissimus lumborum (LL) muscle fibres were characterized and LL quality indicators determined. The correlation was estimated between the LL fibres traits and daily live weight gain, muscle pH and texture parametres. Muscle fibres were identified as I, IIA and IIB types based upon their dehydrogenase (NADH) activity. Th...

The effects of methanolic extract and leaf powder of Artemisia annua were studied on performance, cellular and humoral immunity in 240 Cobb broiler chicks in a completely randomized design. Control group did not receive any treatment. The chicks in the second and third groups were fed with feed which contained 2000 and 4000 ppm plant extract in diet and in the groups 4, 5 and 6 chicks received ...

the effect of a commercial probiotic (protexin) on growth performance and survival rate in sobaity sparidentex hasta was investigated. 240 fish with average weight of 2.99±0.87g were treated for 10 weeks. this study was carried out in a completely random design with 12 experimental groups, in 4 treatments each with 3 replicates. experimental groups were consisted of four levels of 0.0, 0.5, 1.0...

Background: Infants may lose their body resources after surgery due to inadequate nutrient intake and undergoing long periods of fasting after surgery for esophageal atresia, increases risk of several complications. Aim: This study aimed to evaluate the effects of early feeding support on the postoperative weight gain status of infants with esophageal atresia. Method: This randomized, controlle...

Background: Breastfeeding failures and oral feeding problems in preterm infants result in long-term health complications. In this study, therefore, we aimed to evaluate the effect of oral stimulation along with non-nutritive sucking (NNS) on independent oral feeding initiation and weight gain in preterm infants. Methods: This prospective randomized clinical trial was carried out at Aliasghar Ho...

Introduction After the introduction of surfactant, the survival rate of preterm neonates has increased significantly. This issue attracted much attention towards this fragile population. Many studies have demonstrated that massage plays a role in the weight gain of preterm infants. This study compares the effect of massage therapy on infants who were massaged by a nurse or their mother with tho...
