This present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg(-1) phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. The results of experiment have shown that egg weight was increased by supplementation of 12 g kg(-1) feed additive whereas egg production, ...

This study was designed to evaluate efficacy of polyherbal hypocholesterolemic supplement AV/HLP/16 (test compound) on serum and egg yolk cholesterol levels and egg quality parameters in layers. One hundred and twenty healthy White Leghorn (BV 300 strain) of 54 weeks age were randomly divided into four treatments (T 0 , T 1 , T 2 , T 3 ); subdivided into three replicates with ten birds in each ...

the expansion of aquaculture in the last 10 years has made it an important source of protein worldwide.  however, increased production, and the culture intensification it carries, results in higher risk of infectious disease due to poor water quality and high stocking densities. disease has several negative effects on fish, which include reduced feed efficiency, impaired growth and death, repre...

Introduction Following the European ban of antibiotic growth promoters (AGPs) in 2006, the use of organic acids in animal nutrition has gained significant importance in the feed industry. Their positive effects on feed quality and animal performance have been known for decades and, as they increasingly capture the attention of the feed industry, there is a growing need to define the several aci...

Variable rate application of fertilisers with traditional spinner-type spreaders is known to suffer from spread pattern uniformity variability as a function of application rate. To demonstrate this variability, simulations using models from the literature were carried out for two cases: (1) a dual disc spreader with segment-type feed gates; and (2) a single disc spreader with conical feed gates...

In this research, the effects of the rotational speed, feed rate, tool material and lubricants on the tool life and the hole quality are studied in the frictional drilling of the titanium sheets. The friction drilling tests are performed on a CNC milling machine. Furthermore, 5 specimens are selected and their metallurgical structures are studied. The results show thatamong the input parameters...
