A digestibility trial was conducted to examine the effect of feeding rate on dry matter, gross energy, crude protein and phosphorus digestibility in Atlantic salmon (Salmo salar). Duplicate groups of fish were fed 0.25, 0.5, 0.75, 1.0, 1.25 and 1.9% BW/day. The faeces were collected by Guelph-type collectors for five successive days. Dry matter, protein and phosphorus digestibility’s were all s...

The remnants of pesticides in livestock feeds have been increased by excessive using of these pesticides so as to meet extreme demands for more feeds. Finding a new strategy for reducing pesticides negative effects is absolutely necessary. Therefore, evaluation of the effects of sodium bentonite on blood parameters, feed digestibility and rumen fermentation parameters in sheep fed diets contami...

The present study was conducted on efficiency of utilization of dietary energy for milk production in lactating crossbred cattle. 18 lactating crossbred cattle of early to mid-lactation, approximate body weight (375.39±23.43 kg), milk yield, parity and stage of lactation were divided into three groups of six animals each and were fed 0, 50 and 100% diammonium phosphate (DAP) in the mineral mixt...

The aim of this study was to determine the most optimal heating time in protection of protein rich feedstuff on digestibility and in vitro ruminal fermentation profile. Proteinous feedstuffs used in this study is soybean meal (Glycine max). This study is designed using one way ANOVA, with five treatments of heating time (T0 (control)= unheated, T1= 10 min, T2= 20 min, T3= 30 m...

18 Producing organic fish diets requires that the use of both fish meal and fish oil is minimized 19 and replaced by sustainable, organic sources. The purpose of the present study was to 20 replace fish oil with organic oils and evaluate the effects on feed intake, feed conversion 21 ratio (FCR), daily specific growth rate (SGR) and nutrient digestibility in diets in which fish 22 meal protein ...

The effect of adding increasing levels (0, 25, 50 and 75 μl/75 ml buffered rumen fluid) of essential oils (EOs) to a basal substrate (50% roughage: 50% concentrate) on ruminal fermentation characteristics was evaluated in vitro by a semi automatic gas production (GP) technique. The EOs used were from Achillea santolina (AS25, AS50, AS75), Artemisia judaica (AJ25, AJ50, AJ75), Schinus terebenthi...

As a byproduct of sewage treatment plants, sludge presents dual characteristics “resource” and “pollution”. While it enriches nutrients from wastewater, also contains portion toxic substances. Moreover, when the organic matter content is low, affects efficiency resource utilization energy recovery (sludge digestion efficiency, consumption incineration systems). Developing new physicochemical-bi...

A trial involving a 2x2 factorial arrangement of treatments was conducted to evaluate two corn silage hybrids (Agromen, AGN35-A42) and (Bayer, A3663) and concentrate levels (25 and 50%) on animal performance. Twenty-four Holstein x Zebu crossbred steers, averaging 335±30kg of BW, were distributed in six randomized blocks to evaluate intake, digestibility, and performance. Treatments consisted o...
