The crop is a known source of Salmonella and Campylobacter contamination. Previously, we evaluated lactic acid in the drinking water during a simulated pretransport feed withdrawal (FW) and reported 0.44% lactic acid significantly (P < 0.05) reduced the number of Salmonella recovered in market-age broiler crops. However, total consumption of the organic acid-treated drinking water was reduced. ...

This experiment was conducted to evaluate the effect of different levels alfalfa saponins on cholesterol metabolism in broilers. A total of 320 Arbor Acres (AA) broilers of 1 day-old were randomly allotted to 4 treatments with five replicates in each treatment, and with 16 broilers in each replicate. The experiment last 49 days. During the stage from 0 to 3 weeks, broilers in the control group ...

A research study was conducted at Peshawar to investigate the effect of Habek mint on the hematology, immunity and overall performance of broilers. One hundred and sixty day-old broiler chicks were purchased from a local hatchery and divided into four groups (A, B, C and D; each group representing four replicates with 10 chicks per replicate). Group A, B and C were respectively given Habek mint...

The effects of graded levels of corn distillers dried grains with solubles (DDGS) were investigated as a partial replacement for sources of protein, energy, and other nutrients for broilers when the digestible amino acid balance was maintained. Zero, 8, 16, and 24% DDGS were incorporated into isonutritive diets at the expense of corn, soybean meal, and dl-Met. Poultry oil, l-Lys, and l-Thr addi...

The effects of environmental temperatures on live performance and carcass characteristics of broilers have been well documented [1, 2, 3]. In addition, Cahaner et al. [4] reported that nutritional requirements are affected by variations in ambient temperature. Amino acid requirements and digestibility in broilers and laying hens at high temperatures is known to vary from those that are raised a...

Energy utilization in broilers as influenced by supplementation of enzymes containing phytase or carbohydrase activities was investigated. Day-old male broilers (480) were allocated to four slaughter groups, thirty broilers in the initial slaughter group and 150 broilers in each of the final slaughter groups on days 7, 14 and 21. Broilers in each of the final slaughter groups were allocated to ...

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,...

The objectives of this study were to compare measurements of retention and prececal (pc) digestibility in evaluating mineral phosphorus (P) sources in 3- and 5-wk-old broilers. A corn-soybean meal-based basal diet was used (0.35% P on DM basis). Anhydrous monosodium phosphate (MSP(a)) or anhydrous dibasic calcium phosphate (DCP(a)) was supplemented to increment the P concentration by 0.08%, 0.1...

Previous study and our laboratory have reported that short-wavelength (blue and green) light and combination stimulate broiler growth. However, short-wavelength stimuli could have negative effects on poultry husbandry workers. The present study was conducted to evaluate the effects of human-friendly yellow LED light, which is acceptable to humans and close to green light, on broiler growth. We ...

Major objectives of this study were to assess antioxidant protection and fatty acid profile in lung mitochondria and whole liver in broilers with pulmonary hypertension syndrome [(PHS; with and without high dietary vitamin E (VE)] (Experiment 1) and in broilers that did not develop PHS but were genetically selected (S) or not selected (NS) for resistance to PHS (Experiment 2). In Experiment 1, ...
