This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Large White turkey breeder hens were tested in a 4 X 3 factorial design to evaluate the effect of three different levels of physical feed restriction on subsequent reproductive performance. The feed treatments comprised: Control Control (CC) - ad libitum fed throughout the study, Control Restricted (CR) - feed restricted from 16-24 WOA, Restricted Control (RC) - feed restricted from 3-16 WOA and Restricted Restricted (RR) - feed restricted from 3-24 WOA. Feed restriction was implemented so that restricted fed hens achieved a 45% reduction in BW as compared to Control hens at 16 WOA. From 16-24 WOA restriction was implemented to maintain a slight increase in BW. At the completion of the respective restriction period, hens were gradually released back to ad libitum feeding. At the time of photostimulation (30 WOA) all treatments were divided into sub-treatments by weight: HEAVY, MEDIUM and LIGHT, resulting in four treatments with three sub-treatments within each. All hens continued on ad libitum feeding throughout a 20 wk lay cycle. Body weight (BW) for all treatments differed significantly (P

Book Synopsis Reproductive Performance of Turkey Breeders as Influenced by Feed and Light Restriction by : Kenneth Kay Krueger
Download or read book Reproductive Performance of Turkey Breeders as Influenced by Feed and Light Restriction written by Kenneth Kay Krueger and published by . This book was released on 1976 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Restricting day length or feed consumption in winter-hatched Broad Breasted White turkeys were studied for their effects on reproductive performance. Turkey males were either full-fed and received 15, 12 or 8 hours of light per day or restricted-fed and received 15 hours of light per day from 18 through 64 weeks of age. Dark-housed (8 hours of light per day) turkey breeder hens were either full-fed or restricted-fed from 22 to 30 weeks of age. At lighting (30 weeks of age) the full-fed and restricted=fed hen groups were randomly divided and full-fed either 14% or 18% protein diets through 20 weeks of egg production. Turkey males exposed to an 8 hour day produced semen with significantly (P (less than or equal to) 0.05) higher sperm cell concentration over a 30 week collection period than did males receiving 15 hours of light per day. A significant decline in semen volume occurred in full-fed turkey males receiving 15 hours of light per day while full-fed males exposed to 12 or 8 hours of light per day produced increasing semen volumes over the collection period. Mechanically restricting daily feed consumption by approximately 50% (as compared to full-fed males) in turkey males from 18 through 64weeks of age resulted in a 30% reduction in body weight. Restricted-fed males produced increasing semen volume over a 30 week collection period with significantly (P (less than or equal to) 0.05) higher sperm cell concentrations than males full-fed and receiving 15 hours of light per day. Fertility over a 20 week egg production period was significantly higher (P (less than or equal to) 0.05) for restricted-fed males receiving 15 hours of light per day than for full-fed males receiving 15, 12 or 8 hours of light per day. Data presented suggests that the seasonal decline in semen quantity and quality in off-season turkey breeder males may be prevented through the use of feed or light restriction.
