This study was conducted to determine the effects of three different fat sources and their combination on growth performance, carcass traits and intestinal measurements of broiler chickens reared to 42 d of age. Two hundred day-old male broiler chicks (Ross 308) were randomly assigned to one of five treatments with four replicates of 10 chicks based on a completely randomized design. The dietar...

The poultry industry is now operating under increased regulatory pressure following the introduction of the pathogen reduction and hazard analysis critical control point (HACCP) rule in 1996. This new operation scheme has greatly increased the need for on-farm food safety risk management of foodborne bacteria, such as Salmonella. Information needed to make informed food safety risk management d...

OBJECTIVE This study was conducted to investigate the effect of dietary onion (Allium cepa) extract (OE) supplementation on growth performance, apparent total tract retention (ATTR), blood profile, carcass characteristics and meat quality in broilers. METHODS Four hundred male broiler chicks (Ross 308, 3-d old) were randomly allocated to four dietary treatments for 28 d feeding trial. Each tr...

The effect of acidic, electrolyzed oxidizing (EO) water and chlorinated water on the spoilage microflora of processed broiler carcasses was examined. Carcasses were sprayed for 5 s at 80 psi with tap, chlorinated, or EO water in an inside-outside bird washer. Treated carcasses were then stored at 4 degrees C for 0, 3, 7, or 14 d, and the microbial flora of the carcasses was sampled using the wh...

Twelve (12) weeks feeding trial was conducted to determine the effect of fatty acid content/total lipid and carcass characteristics/organoleptic qualities of broiler fed diets supplemented with dietary fat sources at levels of 5% saturated and 5% unsaturated. Three experimental diets identified as T1, T2 and T3 were formulated, the control diet T1 was with 0% fat, T2 contained palm oil at 5% in...

The whole carcass rinse (WCR) procedure is routinely used as a sampling method for determining the presence and number of quality-indicator organisms or pathogens associated with broiler chicken carcasses in processing facilities. Collection of a cumulative drip sample by placing collection vessels under the processing line could potentially capture a more representative sample of bacterial pop...

A Bayesian method for QTL analysis that is capable of accounting for heterogeneity of variance between sexes, is introduced. The Bayesian method uses a parsimonious model that includes scaling parameters for polygenic and QTL allelic effects per sex. Furthermore, the method employs a reduced animal model to increase computational efficiency. Markov Chain Monte Carlo techniques were applied to o...

One hundred and fifty (150) Anak-2000 day-old broiler chicks were used to investigate the effect of toasted white sesame seed meal (TWSSM) as a source of methionine on growth performance, carcass characteristic, haematological and biochemical indices of broiler finisher chickens. The chicks were randomly assigned to five dietary treatments consisting of three replicates of ten chicks per replic...
