Problem statement: Acute heat stress at marketing age especially in broiler chickens raised in open houses with reduced means of heat exchange leads to economic losses. The objective of this study was to determine beneficial effects of early age thermal conditioning in reducing adverse effects of acute heat stress and decrease losses. Approach: Ninety one day-old broiler chicks were randomly as...

background & aim: medicinal plants is very potential to be used as a supplementary feed as well as feed additive in broilers.this experiment was conducted to investigate the effects of milk thistle (mt) and thyme seeds (ts) on the performance in broilers. experimental: in this study, 160 one-day-old (ross 308) male broiler chicks were divided randomly into four major groups with 4 replicate...

three-hundred and twenty 7-day-old ross 308-strain broiler chickens were fed diets containing 0 or 125 ppb aflatoxin b 1 (afb1) from 7 to 28 days of age. sodium bentonite (0.5%), yeast (saccharomyces cervisiae) 0.2%, hydrated sodium calcium aluminosilicate (hscas) (0.5%), ammonia (0.5%), formycine (0.1%), and toxiban (0.1%) were added to the basal diet, as fed basis to determine the effects of ...

The present study was carried out to determine the effects of using dried rose dreg (DRD) as an alternative litter material for broiler performance and microbiological characteristics of litter. A total of 225 day-old broiler chicks was raised on pine wood shavings (PS), DRD and PS+DRD until 42 days. The effects of litter material on broiler performance and FCR did not differ. At 42 days the ef...

The objectives of this experiment was to evaluate the subsequent growth and organ weights, blood profiles and cecal microbiota of broiler chicks fed pre-starter diets containing fermented soybean meal products during early phase. A total of nine hundred 1-d-old chicks were randomly assigned into six groups with six replicates of 25 chicks each. The chicks were fed control pre-starter diet with ...

The study was conducted on 72 day old straight run commercial broiler chicks (DOC) till 6 weeks of age to investigate the effect of Tulsi (Ocimum sanctum) leaf powder (TLP) on the hematological parameters of broilers. Chicks were randomly divided into four groups of 18 chicks each. Control group received standard broilers diet. Chicks in second, third and fourth group received standard broilers...

This study evaluated the behavior of broiler chickens subjected to thermal stress during different periods day and age birds. A total 180 one-day-old male chicks were allocated three chambers. Each chamber contained five boxes, with 12 chicks/box. Birds assigned a completely randomized design. The birds filmed, images recorded every minute two periods: morning (from 08:00 09:00 h) afternoon 17:...

Immunomodulatory effects of Flumequine and enrofloxacin were evaluated on humoral immune response of Newcastle disease virus (NDV) vaccinated broiler birds. It was observed that birds receiving flumequine as growth promoter had higher mean body weights, better feed conversion ratio, higher NDV haemagglutination inhibition (HI) antibody, lesser overall mortality, 100% protection against challeng...

The experiments were conducted to determine effects of a mixture of conjugated linoleic acid (CLA) isomers on T cell subpopulations and responsiveness to mitogen of splenocytes in male broiler chicks. In experiment 1, birds (8-d old) were fed basal, CLA-(CLA) and safflower oil-supplemented (SA) diets which were formulated by supplementary 10 g CLA or safflower oil/kg to the basal diet for 14 d....
