In four trials, lactic-acid-producing bacterial cultures were applied to the skin of live broilers 24 h before slaughter to determine whether inoculation of the cultures could affect the numbers of bacteria that are normally found on the skin of processed broiler carcasses. The cultures contained 10,000 to 100,000 cfu/mL and were sprayed in 250 mL of a pH 6.0 nutrient medium (including glucose,...

In this study, we screen the proteolytic activity of Bacillus species in meat and bone meal (MBM) investigate effects fermented MBM–soybean products (FMSMPs) on growth performance broilers. Trial 1, FMSMPs were using four strains—Bacillus siamensis M3 (M3), B. velezensis M5 (M5), subtilis M6 (M6), M20 (M20)—all which presented more total peptides higher degrees hydrolysis (DH) than var. natto N...

The objective of our study was to test amaranth grain or dried biomass in the diet for broiler chickens as a resource of protein replacing animal protein. Further, the effect of amaranth on broiler performance, carcass characteristics and meat quality were assessed in a feeding trial. The experimental groups of broilers were fed feed mixtures with crude amaranth grain (AC), heat processed amara...

This 42-day experiment was undertaken to compare the nutritional value of insect-protected corn event MON810 (YieldGard) and YieldGard x herbicide-tolerant corn event GA21 (Roundup Ready) to their nontransgenic controls as well as four different commercial reference corns, when fed to growing Cobb x Cobb broilers. A randomized complete block design was used, and each treatment was replicated wi...

Lipid and glucose metabolism of 76 ten-day-old Cobb male broilers, experimentally infected with Eimeria acervulina, was studied for 30 days. Birds were distributed in 2 groups: one infected with 1x10 E. acervulina sporulated oocysts, and the other inoculated with distilled water. Pathological e biochemical liver changes were assessed, as well as plasma glucose concentrations and total cholester...

A study was conducted to investigate the effects of thermostable phytase supplementation on the growth performance and nutrient digestibility of broilers for 42 d. 1-day-old Arbor Acres chicks with similar initial body weight were randomly divided into 3 treatments consisting 6 pens of 20 chicks per pen. The control group was given maize-soybean meal basal diet and the other two groups were fed...

Experiments were conducted to determine the digestible lysine (DLys) requirement of Liuzhou Mahua broilers from 1 to 21 d and from 22 to 42 d of age. Monofactorial design was adopted in this study. 1200 one-day-old healthy broiler chicks were divided randomly and evenly into five treatments, and were all fed with isoenergetic diet (with ME of 3.0 Mcal/kg) but with graded levels of DLys: 1.22%, ...

The goal of this study was to investigate the effects Lactobacillus plantarum (L. plantarum) supplementation on growth performance, nutrient digestibility, gas emission, excreta microbiota, and meat quality in broilers. A total two hundred eighty-eight, one-day-old Ross-308 chicks (mixed sex) were randomly allocated one treatments with eight replicated cages (18 per cage). For a period 35 days,...

The objective of this study was to investigate the protective effect of dietary natural sorbent-sodium humate (HuNa) on the prevention of aflatoxin B1 (AFB1) toxicity in the broiler chicken. Seventy-two (72) broiler hybrid Hybro birds were randomly divided into 4 groups: control group (G1) and 3 experimental groups (G2-G4) with addition of HuNa (G2); only AFB1 (G3) and HuNa; and AFB1 (G4). HuNa...

Research with adult mammals has shown that the diet-induced thermogenesis (DIT) related to the oxidation of macronutrients has a negative feedback on feed intake (FI), depending on the nutrient considered: proteins are combusted first, then carbohydrates and finally fat, corresponding to their satiating ability. However, previous studies revealed no significant differences in DIT between broile...
