Turkeys ( Meleagris gallopavo ).
British Poultry Science, 20111. Ultrastructural changes that take place in the spermatids of the turkey were studied. Twelve steps of spermiogenesis are described. 2. Acrosomal formation is similar to that in the domestic fowl and quail. The perforatorium develops as a dense granule in a tubular invagination of the thickened part of the nuclear membrane during the acrosomal phase ...

Sleep characteristics in the turkey Meleagris gallopavo
Physiology & Behavior, 2003Electrophysiological and behavioral characteristics of the states of vigilance were analyzed in chronically implanted specimens of the turkey Meleagris gallopavo (M. gallopavo). Five different states of vigilance were observed throughout the nyctohemeral period: active wakefulness (AW), quiet wakefulness (QW), drowsiness (D), slow wave sleep (SWS) and ...

Plasma lipoprotein distribution in the turkey (Meleagris gallopavo)
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2001The plasma lipoprotein profile has been determined in fasted 7-week-old male turkeys. Lipoprotein classes were subfractionated by density gradient ultracentrifugation. According to phospholipid concentration over the density gradient, an initial peak was visible in the usual LDL density range, whereas two peaks were detected in that of HDL.

Mycoplasma iowae in turkeys (Meleagris gallopavo)
World's Poultry Science Journal, 2013Mycoplasma are a successful group of pathogens because of their ability to enter and colonise a host, whilst, at the same time, evading the bird's immune response. Mycoplasma iowae (MI) is no exception and, while mostly being a pathogen of turkeys, it can be found in other domestic poultry.

Matrix metalloproteinase activities of turkey (Meleagris gallopavo) bile
Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2001The bile from turkey (Meleagris gallopavo) gall bladders was found to contain substantial matrix metalloproteinase (MMP) activities using gelatin, collagen, and casein substrate zymography, [3H]labeled collagen degradation assays, and gelatin-agarose affinity purification.

Phenotypic characterization of the Guajolote (Meleagris gallopavo gallopavo) in Mexico
Animal Genetic Resources Information, 2008SummaryThe study was conducted to investigate the phenotypic diversity of Guajolote present in small backyard poultry operations. From September 2004 to July 2006, in 54 municipalities in the coastal region of Oaxaca, Mexico 768“guajalotes”growers were visited.

The immunoglobulin light chain locus of the turkey, Meleagris gallopavo
Veterinary Immunology and Immunopathology, 2012To date, most jawed vertebrate species encode more than one immunoglobulin light (IgL) chain isotypes. It has been shown that several bird species (chickens, white Pekin or domestic duck, and zebra finches) exclusively express lambda isotype. We analyze here the genomic organization of another bird species turkey IgL genes based on the recently ...

The Nasal Gland in Turkeys (Meleagris gallopavo): Anatomy, Histology, and Ultrastructure
Avian Diseases, 2019This study provides a detailed description of the major morphoanatomic and ultrastructural features of the nasal gland in turkeys. In this avian species, nasal or salt glands are bilateral, pale pink, elongated to spindle-shaped, serous, tubuloalveolar structures, with a mean length ranging from 0.64 ± 0.15 cm in poults of 4 days of age to 2.15 ± 0.17 ...

Characterization of prolactin receptor in meleagris gallopavo
1997Prolactin receptor (PRLR) is a membrane anchored protein mediating the biological actions of prolactin. The turkey PRLR (tPRLR) cDNA was isolated and characterized. The open reading frame (ORF) of tPRLR predicted 831 amino acid residues composed of a signal peptide, an extracellular domain (ECD), a single transmembrane domain and an intracellular ...

Precocial sexual behaviour in turkeys (Meleagris gallopavo L.)
Animal Behaviour, 1970Abstract Precocial struts were observed in 95 per cent of turkey poults of both sexes, wild and domesticated. In male turkey poults it occurred with about constant frequency up to day 100 (domesticated turkey: 0·6 struts per hr of observation time; wild turkeys: 0·1 struts per hr observation time) and dramatically increased in frequency after day 130,
