Transforming Feather Meal Into a High-Performance Feed for Broilers.

Background: The poultry industry faces challenges with the high cost and environmental impact of Soybean meal. Feather meal, a byproduct with low digestibility due to its keratin content, is a potential alternative. Recent biotechnological advances, including enzymatic and bacterial hydrolysis, have enhanced its digestibility and nutritional value.

Effects of different lipid sources on performance, blood lipid parameters, immune system activity, and expression of TNFα and TLR4 genes in broiler chickens.

This study aimed to explore the effects of different lipid sources on the performance, blood lipid parameters, immune system activity, and the expression of TNFα and TLR4 genes in broiler chickens. A total of 500 one-day-old male chicks of the ROSS 308 commercial strain were allocated into four treatment groups with five replicates each (each replicate comprised of 25 chickens), following a randomized design. The treatments were as follows: (1) a diet incorporating palm oil (PO, a source of saturated fatty acids); (2) a diet incorporating flaxseed oil (FO, a source of omega-3); (3) a diet incorporating soybean oil (SO, a source of omega-6); and (4) a diet incorporating olive oil (OO, a source of omega-9).

The effects of probiotic and threonine application on the carcass yield, internal organ development, intestinal morphology and cecal microbiota of broilers challenged with Clostridium perfringens.

The aim of this study was to explore the effects of probiotics (Ecobiol®) and threonine supplements on broiler internal organs and intestinal health under Clostridium perfringens challenge. A total of 1600 male Ross 308 broiler chicks were randomly assigned to eight treatments with eight replicates each of 25 birds. Dietary treatments consisted of two levels of supplemented threonine (without and with threonine supplementation), two levels of probiotics (Ecobiol®) supplement (0 and 0.

Pasta wastes, as substitute for corn, in the laying Japanese quails diet: Effects on production performance, egg quality and blood biochemistry.

Background: Animal food shortage and finding efficient ways to produce poultry products are getting more and more important issues in the world.

Objectives: This study was aimed to determine the effect of replacing corn with pasta wastes (0%, 50% and 100%) in the diet on production performance, some blood variables and the egg quality traits of laying quails.

Methods: A total of 240 laying quails were allocated into 3 experimental groups with 8 replicates for 8 weeks.

Evaluation of lactic acid bacteria isolated from poultry feces as potential probiotic and its competitive activity against .

The efficacy of probiotics as alternatives to antibiotics has been defined as one of the potential strategies to prevent spp. infection in poultry. The purpose of this study was to isolate probiotic native Lactic acid bacteria (LAB) with high compatibility to intestinal tract and prevention of from broiler chicken feces.

Effects of probiotic lactic acid bacteria on growth performance, carcass characteristics, hematological indices, humoral immunity, and IGF-I gene expression in broiler chicken.

The effects of screened lactic acid bacteria strains were evaluated on growth performance, humoral immunity, and IGF-1 gene expression in broiler chickens. The three dietary groups of negative control fed basal diet, the native LAB probiotic group (NP), and PrimaLac commercial LAB probiotic (PC) were studied. The results revealed that NP and PC diets significantly improved feed conversion ratio and increased body weight, as well as relative weight of carcass compared with group fed NC diet (P < 0.

Effects of Injection and Inclusion a Blend of Essential Oils and Organic Acids in High NSPs Diets of Broiler Breeders on Performance of Them and Their Offspring.

Two factorial completely randomized design trials 2×2 and 2×2×2 were conducted to evaluate the effect of a blend of essential oils and organic acids (Biacid™) in broiler breeder diets at two levels, two dietary non-starch polysaccharides (NSPs) levels and injection of Biacid™ on their progenies performance, respectively. 240 broiler breeders of Ross 308 strain were fed from the age of week 44 for 12 weeks in four groups. 120 produced eggs from each group were divided in two groups of 60 eggs for injecting by 0.
