2002 journal article

Effects of the tricothecene mycotoxin diacetoxyscirpenol on egg production of broiler breeders

Poultry Science, 81(12), 1807–1810.

By: J. Brake n, P. Hamilton n & R. Kittrell n

author keywords: mycotoxin; broiler breeder; diacetoxyscirpenol; tricothecene; egg production
MeSH headings : Aging; Animals; Chickens / physiology; Diet; Egg Shell / anatomy & histology; Egg White; Egg Yolk; Eggs; Female; Mycotoxins / administration & dosage; Mycotoxins / pharmacology; Organ Size; Oviposition / drug effects; Trichothecenes / administration & dosage; Trichothecenes / pharmacology
TL;DR: Long-term consumption of DAS at levels that might naturally occur appears to have little effect on broiler breeder egg production and egg quality of broiler breeders. (via Semantic Scholar)

2000 journal article

Effects of the Trichothecene Mycotoxin Diacetoxyscirpenol on Feed Consumption, Body Weight, and Oral Lesions of Broiler Breeders

Poultry Science, 79(6), 856–863.

By: J. Brake n, P. Hamilton n & R. Kittrell n

author keywords: mycotoxins; tricothecene; broiler breeder; mouth lesions; feed refusal
MeSH headings : Animals; Body Weight / drug effects; Chickens / physiology; Eating / drug effects; Female; Male; Mouth Diseases / chemically induced; Mycotoxins / adverse effects; Trichothecenes / adverse effects
TL;DR: Evidence that DAS caused decreased BW and feed consumption as well as cytotoxic injury including oral lesions in broiler breeders is provided. (via Semantic Scholar)

1999 journal article

Effects of the tricothecene mycotoxin diacetoxyscirpenol on fertility and hatchability of broiler breeders

Poultry Science, 78(12), 1690–1694.

By: J. Brake n, P. Hamilton n & R. Kittrell n

MeSH headings : Animal Feed; Animals; Chickens / physiology; Female; Fertility; Male; Mycotoxins / pharmacology; Oviposition; Ovum / physiology; Reproduction; Semen; Trichothecenes / administration & dosage; Trichothecenes / pharmacology
TL;DR: Low levels of DAS appeared to improve female-related fertility, presumably because of enhanced spermatozoal storage within the oviduct, and Conversely, DAS decreased male-relatedertility, presumably by direct toxic effects on the testes. (via Semantic Scholar)

1998 journal article

4 beta, 15-diacetoxyscirpenol induces cytotoxicity and alterations in phagocytic and Fc-receptor expression functions in chicken macrophages in vitro

IMMUNOPHARMACOLOGY AND IMMUNOTOXICOLOGY, 20(4), 541–553.

By: M. Qureshi n, M. Brundage n & P. Hamilton n

MeSH headings : Animals; Antineoplastic Agents / pharmacology; Cell Survival / drug effects; Chickens; Cytotoxicity, Immunologic / drug effects; Female; Macrophages / drug effects; Macrophages / physiology; Male; Mycotoxins / pharmacology; Phagocytosis / drug effects; Receptors, Fc / biosynthesis; Receptors, Fc / drug effects; Receptors, Fc / physiology; Trichothecenes / pharmacology
TL;DR: It is demonstrated that DAS exposure causes a suppression in macrophage phagocytic function and therefore may alter the first line of immunological defense in chickens. (via Semantic Scholar)

1998 journal article

Dietary exposure of broiler breeders to aflatoxin results in immune dysfunction in progeny chicks

Poultry Science, 77(6), 812–819.

By: M. Qureshi n, J. Brake n, P. Hamilton n, W. Hagler n & S. Nesheim  n

author keywords: aflatoxin feeding; broiler breeder; residues testing procedure; progeny immune functions; hatchability
MeSH headings : Aflatoxin B1 / pharmacokinetics; Aflatoxin B1 / pharmacology; Aflatoxins / administration & dosage; Aflatoxins / pharmacokinetics; Aflatoxins / pharmacology; Analysis of Variance; Animal Feed; Animals; Antibody Formation / drug effects; Aspergillus; Brucella abortus / immunology; Carcinogens / pharmacokinetics; Carcinogens / pharmacology; Chick Embryo; Chickens / immunology; Female; Fertility; Macrophages / drug effects; Macrophages / immunology; Oviposition; Phagocytosis / drug effects; Reactive Oxygen Species / metabolism
TL;DR: The findings of this study imply that the progeny chicks from hens consuming a AF-amended diet may be increasingly susceptible to disease owing to suppression of humoral and cellular immunity. (via Semantic Scholar)

DEPOSITION IN EGG-YOLKS OF THE CAROTENOIDS FROM SAPONIFIED AND UNSAPONIFIED OLEORESIN OF RED PEPPER (CAPSICUM-ANNUUM) FED TO LAYING HENS

POULTRY SCIENCE, 69(3), 462–470.

By: P. Hamilton n, F. Tirado & F. Garciahernandez

TL;DR: The influence of saponification on the deposition in egg yolks of the carotenoids from oleoresin of red pepper was investigated and the ah (redness), in particular, and the bh (yellowness) increased significantly. (via Semantic Scholar)
