Supplemental thyroid hormones and molting in turkey breeder hens
Poultry Science, 1997 The objective of the current study was to determine whether thyroid physiology may affect molting time in turkeys. Two trials using approximately 144 hens were conducted to elucidate thyroidal factors that limit the molting process. Thyroid hormones or a thyroid blocker (thiouracil) were given to the hens during a molt by supplementing the diet with ...

Relationship of Body Fat to Fertility in Broiler Breeder Hens
Poultry Science, 1985 Sixty-one dwarf broiler breeder hens (58 weeks of age) were utilized to examine relationships among body weight, body fat, oviduct fat, and fertility. Body weight showed a significant (P less than .05) positive relationship to percent body fat (r = +.26). The correlation coefficient between percent body fat and percent oviduct fat was +.26 (P less than

A Revised Artificial Insemination Schedule for Broiler Breeder Hens
Poultry Science, 1976 Broiler type hens maintained in individual cages were artificially inseminated with either 0.023, 0.035, or 0.047 ml. of pooled semen. Insemination intervals were nine, nine, and ten days on a repetitive basis. This schedule was adopted because it allowed an extension of the conventional insemination interval and yet remained compatible with a five ...

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.Abstract Multispectral three‐dimensional (3D) imaging offers substantial potential for plant phenotyping, yet manual segmentation of plant organs remains a bottleneck in breeding programs. We developed a color‐based filtering workflow for faba bean (Vicia faba L.) point clouds that optimizes lower and upper thresholds of spectral indices and broadband ...

Choline and Tallow in Breeder Hen Diets
Poultry Science, 1956 Abstract The need of choline in the diet of mature hens has been adequately reviewed by Welch and Couch (1955) and Burns and Ackerman (1955). In most of the work cited, it was concluded that dietary choline was required for optimum egg production and hatchability. It was also reported that the hen has a limited ability to synthesize choline.
