Contrary to a commonly held belief that broiler chickens need more space, there is increasing evidence that these birds are attracted to other birds. Indeed, commercially farmed birds exhibit a range of socially facilitated behaviours, such as increased feeding and preening in response to the presence of other birds. Social facilitation can generate feedback loops, whereby the adoption of a par...

The embryonic modal value of heart rate (MHR) differs between broiler and White Leghorn chickens, but the initial development of cholinergic chronotropic control of embryonic heart rate (HR) does not. Thus, we hypothesized that hatchling MHR should also differ between broiler and White Leghorn strains, while the development of a physiological regulation, such as the endothermic HR response, sho...

Residues from cereal grain production are important feedstuffs for ruminants throughout the world. They are, however, low in protein and high in fiber, which limit feed intake and digestibility. The nutritive value of cereal crop residues can be improved by various processing methods, such as treatment with alkalis like sodium hydroxide or ammonia. Another means of improving nutritive value of ...

The application of broiler manure and bedding (litter) on land has been a long-used disposal method that benefits plant and soil. For proper manure management, factors such as nutrient content, house cleaning management, application methods, and many land, crop, and climatic factors must be considered. A study was undertaken to characterize broiler cake and broiler litter as the by-products of ...

A study was conducted with green tea (GT) and biotite to evaluate their effect on broiler growth, meat quality, and the development of internal organs. A total of 210 Ross day old chicks (DOC) were distributed to 6 dietary feed additive groups having 5 treatments with 7 chicks in each group. The groups were control (basal), antibiotic (basal + 30 ppm oxytetracycline), GT (0.5 and 1.0% with basa...

AIM The study was conducted to evaluate the attribution of antibacterial and antioxidant activity of methanolic extract of Cassia tora toward its growth promoting effect in broiler birds. MATERIALS AND METHODS A limit test was conducted for C. tora extract in Wistar albino rats. Phytochemical screening of methanolic extract of leaves of C. tora was carried out. In-vitro antibacterial activity...

Sudden death syndrome has developed into a major problem to the broiler industry in many parts of the world. Broilers of all ages are affected starting as early as 2 days of age and continuing through to market age. Peak mortality usually occurs between 3 and 4 weeks of age. (Gardiner et al.,1988) The syndrome has been reported to cause between 1.31 and 2.46per cent mortality with males more co...

We examined 29 isolates of Salmonella enterica subspecies enterica serovar Schwarzengrund from broiler chickens (n=19) and retail chicken meats (n=10) in Japan for antimicrobial susceptibility and pulsed-field gel electrophoresis (PFGE) profiling. All isolates exhibited resistance to both bicozamycin and sulfadimethoxine (minimum inhibitory concentration of both antimicrobial agents: >512 micro...

An experiment was carried out to evaluate the effect of five commonly used antistress agents on haemato-biochemical profiles of broiler and broiler breeder hen. In case of broiler, significant differences were observed between treatment groups for haemoglobin concentration, total RBC and total WBC count, total blood glucose, total serum protein, total serum albumin, total alkaline phosphatase a...
