Daylength used as a management tool has powerful implications on the welfare of both broilers and turkeys. Near-constant light results in many detrimental impacts, including lack of behavioural rhythms and circadian melatonin rhythms. Both are suggestive that sleep fragmentation could result in birds reared on long photoperiods, which can lead to the same negative health and physiological respo...

Pathogens in the genus Campylobacter are the most common cause of food-borne bacterial gastro-enteritis. Campylobacteriosis, caused principally by Campylobacter jejuni and Campylobacter coli, is transmitted to humans by food of animal origin, especially poultry. As for many pathogens, antimicrobial resistance in Campylobacter is increasing at an alarming rate. Erythromycin prescription is the t...

The article presents data on pathomorphological changes of the digestive organs in associative course heterakidosis and histomoniasis turkeys. Changes liver were observed 57.1% cases: protein fatty dystrophy, hepatocyte necrosis. cеcal lesions 100% cases, mainly fibrinous inflammation. In other parts intestinal tract – acute catarrhal

Abstract Semen quality and fertility in crossbreeding between white plumage black indigenous turkey hens using artificial insemination were investigated. Eighty-two healthy turkeys, comprising 72 (Thirty-two forty white) 10 toms (five five used. The turkeys grouped into four treatments based on the breeding plans: T1 (White X White hens), T2 (Black Black T3 hens) T4 hens). was harvested from to...

Quantitatively and qualitatively most important metabolites of the indispensable polyunsaturated fatty acids (PUFA) of the n-6 (linoleic acid, LA) and the n-3 (α-linolenic acid, LNA) series are arachidonic acid (AA), and eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), respectively. In the present experiment, AA content, long-chain n-3 PUFA equivalent (LCE; calculated as 0.15 LNA + E...

HREE live poultry viruses-fowl pox, Rous sarcoma and Newcastle diseasehave been employed experimentally at the Agricultural Research Center, Beltsville, Maryland, iin studies designed to test their action on parthenogenesis in eggs of Beltsville Small White (BSW) turkeys. Each of the viruses was found to have an enhancing influence on cells of parthenogenetic origin (OLSEN 1956, 1961; OLSEN and...

A study was conducted utilizing two strains of male Large White turkeys (BUT Big 6 and Nicholas 700) to determine the effects of increasing Arg:Lys ratios on live performance and carcass composition. Diets were formulated to provide 100, 110, and 120% of NRC (1994) Lys levels, adjusted for dietary energy level, with Arg:Lys ratios of 1.0:1, 1.1:1, 1.2:1, and 1.3:1 in a 3 x 4 factorial arrangeme...

Compared with quadrupeds, bipedal runners of the same weight have longer legs, take longer steps and can presumably use slower, more economical muscle fibers. One might predict that bipedal running is less expensive, but it is not. We hypothesized that bipeds recruit a larger volume of muscle to support their weight, eliminating the potential economy of longer legs and slower steps. To test our...

There is a gap in knowledge of microbiological quality in raw chicken products produced by nonconventional methods and no studies have reported the microbiological quality of turkeys produced under different rearing environments. Thus, the aim of this study was to compare the microbiological quality of conventionally and organically reared whole chicken and turkey carcasses purchased from 3 ret...
