S OF PAPERS 213 M72 Relationship of Hatch Time to Broiler Chick Percentage Yolk Sac and Subsequent Live Performance John Brake*1, Serdar Ozlu2, Okan Elibol2 1North Carolina State University, Raleigh, NC; 2University of Ankara, Ankara, Turkey Broiler hatching eggs from broiler breeder flocks (Ross 344 X 308SF) at 59 and 55 wk of age were used in Experiments 1 and 2, respectively. Eggs were store...

Current understanding of the factors influencing hawksbill sea turtle (Eretmochelys imbricata) hatch success is disparate and based on relatively short-term studies or limited sample sizes. Because global populations of hawksbills are heavily depleted, evaluating the parameters that impact hatch success is important to their conservation and recovery. Here, we use data collected by the Jumby Ba...

the accuracy of stereolithography (sl) product is very essential for meeting the intended functional applications. the parameters like layer thickness, hatch spacing, hatch overcure contribute significantly to the accuracy of the sl parts. in this paper an attempt has been made to identify the process parameters that influences on the accuracy of the parts made with ciba tool 5530 and optimize ...

This study was conducted in two steps to determine the effects of in ovo injection of zinc acetate (ZAC) on some gene expression associated with embryonic growth and development, and with growth and carcass characteristics of the resultant chicks. In the first step the effect of in ovo injectionofZAC on the expression of insulin-like growth factors (IGFs:IGF-I and IGF-I), myog...

This study determined the availability of glycerol as indicator of energy status of broiler chicks during hatch, and the behavior of chicks subjected to three fasting times with reference to production standards. Chicks originating from 31 and 54 week-old Ross breeder flocks were utilized. Samples of liver were taken from chicks during the following time periods: pipping of eggshell, wet hatch,...

The aim of this study was to evaluate the effects of dietary vitamin E on reproductive and productive parameters in Japanese quails. A total number of 240 female and 80 male Japanese quail were divided into five treatments with four replications in a completely randomized design. Experimental diets were zero control, 30, 60, 120 and 240 mg kg-1 of vitamin E. Fertility and total hatch...

Wheat germ oil was added to a larval liquid diet for rearing Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) to optimize fruit fly quality. Effects of various concentrations of wheat germ oil at 0.04, 0.07, 0.15, 0.30, and 0.66% and their possible mode of action were evaluated. Results suggest that addition of wheat germ oil does not affect pupal weight, larval developmental period, adult e...

We examined biochemical changes accompanying feeding and starvation from hatch to Stage VI (day 74 after hatch) in spiny lobster, Jasus edwardsii, phyllosoma larvae. Larval dry weights (dw) increased 17-fold from hatch (80+/-1 microg) to Stage VI (1415+/-44 microg). Larvae starved for 6-11 days at Stages II, IV and VI were 14-40% lighter than their fed counterparts fed enriched Artemia. The inc...

introduction criteria for starting weight-bearing on the heel with a symptomatic calcaneal insufficiency fracture have not yet been reported. case presentation we describe a rare case of a 52-year-old woman with a calcaneal insufficiency fracture who sustained a second ipsilateral calcaneal insufficiency fracture within a short time span. the initial fracture was not evident radiographically, b...
