Objective(s): Echis carinatus is one of the venomous snakes in Iran. The venom of Iranian Echis carinatus is a rich source of protein with various factors affecting the plasma protein and blood coagulation factor. Some of these proteins exhibit types of enzymatic activities. However, other items are proteins with no enzymatic activity.   Materials and Methods: In order to study the mechanism ...

The chemical composition and in vitro gas production of some leguminous browse species were evaluated. Crude protein (CP) content was highest (P

Phytate in poultry rations containing rice bran (RB) critically reduce poultry performance while increasing N and P excretion. The objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. Twenty days old male broiler chicks (n=180) in 60 floor pens wer...

Abstract Background The aim of this study is a comparison between some different protein sources in sheep rations to identify the best source that achieves highest production performance and lowest economical feed efficiency. Twenty Farafra male lambs weighed on average 41.39 ± 1.66 kg were divided randomly into four similar groups 5 animals each. All fed concentrate mixture (CFM) at 3% their b...

The objective of this study was to evaluate the effect of crude glycerin inclusion levels on BRS Capiaçu grass (Pennisetum purpureum) silage on the parameters of fermentation and chemical-bromatological composition. Experimental treatments consisted of BRS Capiaçu grass silage with five levels of inclusion of crude glycerin (0, 1, 5, 10 and 15% inclusion in the natural matter) during e...

Search for an adapted forage species for feed production under existing marginal lands and harsh conditions is needed to overcome sever feed shortage in Egypt. Sesbania, Sesbania aegyptiaca (Sesbania sesban, L) has shown potential for forage production and being included in grazing systems, especially on marginal lands and salt–affected soils. An experiment was conducted in the summer of 2004 a...

The potential of cotton seeds to serve as animal feed in reducing feed-food competition between humans and animals was examined this research. Proximate analysis, mineral characterization, fatty acid composition the seed were determined using standard analytical techniques. protein content found be 24.81 ± 0.42% observed above requirement 18% by rabbits chicken 12% for goats sheep. combination ...

1. Twenty-seven energy and protein balances were done using nine cross-bred (Brown Swiss times Sahiwal) mature bullocks in a series of three balance trials. The bullocks were fed 75, 100 and 125 percent of the metabolizable energy (ME) and digestible crude protein standard values recommended by the (US) National Research Council (1966). Heat production was estimated by indirect calorimetry, by ...
