Influence of dried tomato pomace as an alternative to wheat bran in maize or wheat based diets, on the performance of laying hens and traits of produced eggs
In a 2 3 2 factorial arrangement, 144, fifty–four-week-old laying hens, in 12 treatments with 12 replicates for each treatment, received one of 12 diets based on maize or wheat containing three levels of dried tomato pomace (DTP: 0, 50 and 100 g/kg) as a substitute for wheat bran, and two levels of pigment (0 and 900 mg/kg), for 9 weeks. Weight gain (WG), egg production (EP), egg weight (EW...
متن کاملEffects of Barley Cultivar and Dietary Supplemental enzyme on Performance, Egg Quality Traits, and Selected Blood Parameters of Laying Hens
The effect of supplementing two commercial multienzyme to diets included two barley cultivars (Sararood [71.99%] and Valfajr [66.39%]) on performance, egg quality, and blood parameters of laying hens was investigated in an 8-wk (65 to 73 wk of age) experiment. The commercial multienzymes were Grindazym™ (with mainly β-glucanase and xylanase activity) and Hemicell® (with mainly β-mannanase acti...
متن کاملA Comparative Study between the Effects of Feed Inclusion with Garlic (Allium sativum), Cloves and Turmeric (Curcuma longa) Rhizome Powder on Laying Hens’ Performance and Egg Quality
This experiment was conducted, during a seven-week period to investigate, the effects of using various levels of garlic cloves and turmeric rhizome powders, on laying hens’ performance, egg quality characteristics and cholesterol content in yolk. Two hundred and sixteen, 27-weeks old Novogen white laying hens were assigned randomly into nine treatments with eight replicates of three birds each....
متن کاملA comparative study on the colonization of Salmonella enteritidis hilA mutant and its parent strains in laying hens
BACKGROUND: Several regulatory proteins are involved in Salmonella invasion. The key regulator of SPI-1 (Salmonella pathogenicity island 1 ) is hilA, a transcriptional activator encoded on SPI-1 that regulates the expression of the SPI-1 secretion system. OBJECTIVES: Importance of hilA mutation on S. enteritidis colonization and shedding in layer hens was evaluated in a long-term experiment. ME...
متن کاملGenotype and environment effects on feed grain quality
The extent of genotype and location effects on chemical composition and nutritive value of grains fed to animals was surveyed. The review covered the winter cereals (wheat, barley, oats, and triticale), the summer cereals (sorghum and maize), and the pulses (field pea, lupins, faba beans, and chickpea) when fed to cattle, sheep, poultry, pigs, rats, and mice. The bulk of the literature does not...
