an experiment was conducted to evaluate the feeding value of date pits in broiler chickens. one hundred sixty eight male broiler chicks (ross 308) from 1 to 42 days of age were used. experimental design was crd, in a factorial arrangement of 4 replicates per treatment. the factors included: 3 levels of date pits (10, 20 and 30%) either with or without multi enzyme supplementation. a control die...

introduction due to scarcity of forage and water resources and high feed prices in iran, it seems that the utilization of native and cheap forage resources for ruminants is important. the milk thistle (silybum marianum) is distributed in different regions of iran included: gonbad kavoos, gorgan, nodeh kalardasht, dareh hezareh, dasht mugan, poshtkoh, mollassani, shush, hamidieh, ramhormuz, izeh...

Abstract Background This study was conducted to evaluate the clinical effect of Granulocyte Colony Stimulating Factor (GCSF) on prognosis of neonatal sepsis. Materials and Methods Present study is a double- blinded randomized clinical trial, conducted on 46 preterm infants with neutropenia (Absolute Neutrophil Count (ANC) ≤ 5000 / μL) and clinical sepsis. Infants were randomly allocated ...

In this study, the shape and size differences between 30 samples of Garra rufa and Garra variabilis species captured in Tigris River were investigated by using geometric morphometric methods. According to the results of this study, there is no difference between these two species in terms of size (CS); however, they are quite different from each other in terms of shape and this difference is si...

to compare the nutritional value of rapeseed meal and cottonseed meal in holstein cows, feeding 20 lactating holstein cows each with an average weight of 580± 34 kg and 100± 10 days in milk were studied in a randomized complete block design. the experimental diets consisted of 4 levels of 0, 8, 14 and 25 percent rapeseed meal replaced with cottonseed meal and barley grain in the diets. diets we...

The creation of feeding currents by calanoid copepods increases encounter rates of copepods with their food and provides and advantage in dilute nutritional environments. Small-scale turbulence has also been hypothesized to increase the encounter rate between planktonic predators and their food. Centropages hamatus was exposed to turbulent and nonturbulent environments at two prey concentration...

Bombesin's purported role in satiety mechanisms prompted this investigation of its effects on thresholds for stimulation-induced feeding and self-stimulation in the rat. Single electrodes were implanted in the lateral hypothalamus and the ability of each electrode to support self-stimulation and stimulation-induced feeding was evaluated at four current levels between 80 and 320 microA. The freq...

Free-living nematodes are an important group in all benthic habitats. They occur in high abundance and due to the feeding types they have strong influence on bacteria, algae, detritus and meiofauna in periphyton and sediments. The main aims of this study were to determine the vertical distribution of nematodes and their feeding types within the moss-covered tufa barrier over a one year period i...
