The influence of feed restriction during rearing was investigated in male-line Large White breeder hens with regard to effects on ovarian morphology, egg production, laying patterns, and egg characteristics. Two hundred poults were reared from 4 to 28 wk of age under four treatments as follows: full-fed controls (FF), low-protein diet (12% CP from 12 to 28(More)
The influence of feed allowance during rearing was investigated in male-line Large White breeder hens. A flock of 200 poults was reared from 4 to 28 wk of age under four treatments as follows: full-fed controls (FF), low-protein diet (12% CP from 12 to 28 wk; LP), and reduced BW (10 or 20% lower BW than FF; R10 and R20). At photostimulation (28 wk), all(More)
A liquid methionine supplement known as methionine hydroxy analogue-free acid (MHA-FA) was evaluated as a source of methionine in the diet of young broiler chicks. Diets calculated to be deficient in methionine were supplemented with MHA-FA and performance compared to that obtained when comparable diets were supplemented with molar equivalents of methionine(More)
We designed a system using hand-held computers allowing physicians in the hospital setting to access their surgical schedules, to track patients in multiple hospitals, and to quickly enter billing information. The physicians would then update their schedules and pass billing information electronically when they returned to the office. The system was(More)
Three experiments were conducted to compare different methods of short-term potentiation of tetracycline antibiotics for broiler chicks. Reduction of dietary calcium and addition to sodium sulfate were compared in different combinations with various levels of chlortetracycline (CTC) and oxytetracycline (OTC). Reducing dietary calcium from 0.8 to 0.4%(More)
Endoscopic detection of small tumors is key to the early diagnosis and treatment of malignancy. This paper describes a simple, endoscopic detection system which enables tumor localization and a permanent record based on the laser-induced fluorescence of dihematoporphyrin ether (LIFD). Spectral analysis of dihematoporphyrin ether (DHE, Photofrin II) was(More)
Nonproducing, small-type breeder hens in excess of 65 weeks of age were used to represent the maintenance state. All birds had been in laying cages since 30 weeks and accustomed to 16 hr of 70 lx lighting at 16 C. Nitrogen (N) balance was performed in metabolism cages under the same conditions. Ad libitum intake of a common breeder ration led to an intake(More)
Two models are used for the development of practical skills with the fiberoptic choledochoscope. The models allow the surgeon to become comfortable in manipulating the fiberoptic choledochoscope and various tools. Olympus, Pentax and American ACMI fiberopticscopes have been shown using these models. Use of models eliminates the cost and ethics of using live(More)
