Reproductive performance of cows mated to and preweaning performance of calves sired by Brahman vs alternative subtropically adapted breeds.

Comparisons involving Brahman and Brahman-derivative (Brangus, Santa Gertrudis, Beef-master, Simbrah, Braford) sires indicate the following: 1) cows mated to Brangus and Santa Gertrudis bulls had a shorter gestation length than cows mated to Brahman bulls, 2) calves sired by Brangus and Beefmaster bulls were lighter at birth and weaning than calves sired by Brahman bulls, and 3) birth and weaning weights were similar for calves sired by Santa Gertrudis and Brahman bulls and for calves sired by Simbrah and Brahman bulls. Comparisons involving Brahman and other Zebu (Sahiwal, Nellore, Gir, Indu-Brazil, Boran, Romana Red) sires indicate that gestation length was slightly longer for cows mated to Sahiwal and Nellore bulls and that, relative to the Brahman, birth and weaning weights were similar to or lighter for calves sired by bulls of the other Zebu breeds. The only exception to this pattern was birth weight of Indu-Brazil-sired calves, which were heavier than calves sired by Brahman bulls. Comparisons involving Brahman and non-Zebu subtropically adapted (Tuli, Senepol) sires indicate that cows mated to Tuli bulls had a slightly shorter gestation length than cows mated to Brahman bulls and that birth and weaning weights of calves sired by Tuli and Senepol bulls were lighter than those of calves sired by Brahman bulls.

Practices differentiating high-performing from low-performing supported employment programs.

This paper reports on a qualitative study designed to uncover the practices that differentiate programs producing high rates of competitive employment from those with low rates. The study found 13 differentiating practice factors in three areas: building consumer interest in working, getting a job, and maintaining a job. The congruence between these findings and current definitions of "best practice" is discussed.

Factors affecting broiler breeder performance. 7. Effect of varying levels of dietary protein on the development and reproductive performance of the dwarf broiler breeder.

Vedette dwarf broiler breeder female chicks were raised in floor pens and fed a standard starter ration. At 3 wk of age, 1,032 pullets were divided into four dietary treatment groups (258 bird/treatment). Birds were transferred into individual cages at 18 wk of age and at 21 wk of age assigned to one of four laying rations. Dietary treatments consisted of a 4 X 4 factorial design with four developer diets (12, 14, 16, and 18% protein) and four layer diets (12, 14, 16, and 18% protein). Body weight was determined at 6, 12, and 17 wk of age and thereafter at 4 wk intervals. Hen-day egg production was determined weekly from 21 to 58 wk of age. Specific gravity and egg weights were measured at 4-wk intervals on eggs collected over 4-day periods. Fertility and hatchability were measured at 32, 34, and 44 wk of age on the one-half of the birds in each treatment that had been artificially inseminated weekly with .05 mL of semen from Ross males. Embryonic mortality and chick weights of offspring were recorded when the breeder flock was 32 and 44 wk of age. Dietary treatment had a significant effect on body weight (P greater than .05) at Week 12, (12% and 14% vs. 16% and 18%) but by Week 17 differences were no longer significant. Significant differences in body and egg weights during the laying cycle were detected (P less than .05), with hens receiving the higher protein (16% and 18%) laying diets exhibiting heavier body and egg weights.(ABSTRACT TRUNCATED AT 250 WORDS)

Research note: performance of single comb White Leghorn pullets as influenced by niacin supplementation from zero to six weeks of age and subsequent layer performance.

Two experiments were conducted using a total of 288 Hy-Line W-36 day-old Single Comb White Leghorn (SCWL) pullets in each experiment. The pullets were randomly assigned to one of the six dietary treatments that consisted of 0, 1.5, 3.0, 6.0, 12.0 or 36.0 mg supplemental niacin/kg in a corn and soybean meal basal diet that contained 25.1 mg niacin/kg. Six replicates of eight pullets per replicate were used per treatment in each experiment. Feed and water were provided for ad libitum consumption. The pullets were housed in battery brooder pens with raised wire floors. Total feed consumption (FC), BW, BW gain, and feed efficiency (FE) were measured at 3 and 6 wk of age. Birds were observed daily for any signs of niacin deficiency. At the end of a 6-wk experimental period, the pullets that previously received the diets containing either 0 of 36.0 mg supplemental niacin/kg of diet were raised to sexual maturity (SM) and their age at SM, BW at 24 wk, and number of eggs per pullet through 36 wk were measured in both experiments. No differences (P less than .05) in FC, BW, and FE were observed from 0 to 3 or 3 to 6 wk. None of the birds showed any signs of deficiency during the experimental period. No differences were observed in SM, number of eggs laid, and BW at 24 wk. It was concluded from these experiments that SCWL pullets do not require more than 25.1 mg/kg niacin furnished by the corn and soybean meal diet from 0 to 6 wk.

Factors influencing relative financial performance of hospital laboratories. Economic comparisons to measure performance.

When factors that drive hospital laboratory costs are clearly understood, administrators and laboratory directors can make more informed, comprehensive decisions about the laboratory's future. If internal laboratory operations cause higher-than-average relative costs, department managers can work toward improving productivity, efficiency, and decisions about purchased products/services. If, however, external factors, such as unusually high laboratory utilization and service-level expectations of the medical staff cause higher-than-average relative laboratory costs, hospital administration and laboratory managers can determine whether those external factors can be modified to reduce laboratory costs without adversely affecting patient care.
