The present study demonstrates the prevalence of footpad lesions in turkeys and their level of expression in both live birds and in carcasses. In clinical investigations of 11,860 turkeys (5,740 males, 6,120 females) of the strain British United Turkeys Big 6, individuals of all the observed flocks showed alterations to the plantar skin. In general, the degree and severity of skin alterations w...

Within Galliformes, megapods (brush turkey, malleefowl, scrubfowl) exhibit unique forms of parental care and growth. Hatchlings receive no post-hatching parental care and exhibit the most exaggerated precocial development of all extant birds, hatching with fully developed, flight-capable forelimbs. Rather than flying up to safety, young birds preferentially employ wing-assisted incline running....

Low pathogenicity avian influenza virus (LPAIV) and lentogenic Newcastle disease virus (lNDV) are commonly reported causes of respiratory disease in poultry worldwide with similar clinical and pathobiological presentation. Co-infections do occur but are not easily detected, and the impact of co-infections on pathobiology is unknown. In this study chickens and turkeys were infected with a lNDV v...

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...
