Crouch, A. N., Grimes, J. L., Christensen, V. L., & Krueger, K. K. (2002, January 1). Poultry Science.

By: A. Crouch*, J. Grimes n, V. Christensen n & K. Krueger*

author keywords: turkey breeder hen; feed restriction; body weight gain; feed consumption; feed conversion
MeSH headings : Animal Feed; Animal Husbandry / methods; Animals; Body Weight / physiology; Eating / physiology; Female; Food Deprivation / physiology; Oviposition / physiology; Random Allocation; Turkeys / growth & development; Turkeys / physiology
topics (OpenAlex): Animal Nutrition and Physiology; Livestock and Poultry Management; Agricultural Practices and Plant Genetics
TL;DR: Large White turkey breeder hens were fed ad libitum for a 20-wk summer season egg production cycle, feed-restricted from 16 to 24 wk (CR), feed- restricted from 3 to 16 wK (RC), or feed- restricts for 3 to 24Wk (RR), and at the end of the study, cumulative feed consumption was significantly less for restricted treatments.

2002 article

Effect of physical feed restriction during rearing on Large White turkey breeder hens: 3. Body and carcass composition

Crouch, A. N., Grimes, J. L., Christensen, V. L., & Krueger, K. K. (2002, December 1). Poultry Science.

By: A. Crouch*, J. Grimes*, V. Christensen* & K. Krueger*

author keywords: turkey breeder hen; feed restriction; body and carcass composition; prolactin
MeSH headings : Adipose Tissue; Aging; Animals; Body Composition; Body Water; Body Weight; Crop, Avian / anatomy & histology; Female; Food Deprivation; Light; Muscle, Skeletal / anatomy & histology; Organ Size; Oviducts / anatomy & histology; Oviposition; Prolactin / blood; Proteins / analysis; Seasons; Turkeys / growth & development; Turkeys / physiology
topics (OpenAlex): Animal Nutrition and Physiology; Livestock and Poultry Management; Agricultural Practices and Plant Genetics
TL;DR: Further research on quantitative feed-restriction programs, which result in body weight reductions as described in this study, should address specific physiological and nutritional requirements and not be implemented as general programs. (via Semantic Scholar)

1999 article

Restriction of feed consumption and body weight in two strains of large white turkey breeder hens

Crouch, A. N., Grimes, J. L., Christensen, V. L., & Garlich, J. D. (1999, August 1). Poultry Science.

By: A. Crouch n, J. Grimes n, V. Christensen n & J. Garlich n

author keywords: turkey breeder hen; restrictive feeding; body weight; egg production
MeSH headings : Animal Feed; Animal Husbandry; Animals; Body Weight; Eating; Female; Fertility; Male; Turkeys / growth & development
topics (OpenAlex): Animal Nutrition and Physiology; Livestock and Poultry Management; Agricultural Practices and Plant Genetics
TL;DR: It was concluded that early severe feed restriction of female line breeder hens might improve subsequent reproductive performance and achieve the cumulative feed consumption or BW of control fed hens by 56 WOA. (via Semantic Scholar)

Enzyme Supplementation to Enhance Wheat Utilization in Starter Diets for Broilers and Turkeys

Crouch, A. N., Grimes, J. L., Ferket, P. R., Thomas, L. N., & Sefton, A. E. (1997, July 1). The Journal of Applied Poultry Research, Vol. 6, pp. 147–154.

author keywords: body weight; chicks; enzyme; feed conversion; gut viscosity; poults; wheat
topics (OpenAlex): Animal Nutrition and Physiology; Agronomic Practices and Intercropping Systems; Legume Nitrogen Fixing Symbiosis
TL;DR: It was concluded that supplementation of wheat sources for both chicks and poults lowered intestinal viscosity, and enzyme supplementation of NC wheat diets improved performance of chicks andpoults and source of wheat affected chick and poult performance. (via Semantic Scholar)
