Chromium propionate in turkeys: effect on performance and animal safety.

Two hundred eighty-eight male Nicholas Large White turkey poults were used to determine the effect of supplementing turkeys with chromium propionate (Cr Prop) from 1 to 84 d of age on performance and animal safety. Treatments consisted of Cr prop supplemented to provide 0, 0.2, or 1.

Chromium propionate in turkeys: effects on insulin sensitivity.

The objective of this study was to evaluate the effects of dietary chromium (Cr), as Cr propionate (Cr Prop), on measures of insulin sensitivity in turkeys. Plasma glucose and nonesterified fatty acid (NEFA), and liver glycogen concentrations were used as indicators of insulin sensitivity. One-day-old Nicholas Large White female poults (n = 336) were randomly assigned to dietary treatments consisting of 0 (control), 0.

Research Note: Chromium propionate for turkeys: effect on tissue chromium concentrations and human food safety.

This study was conducted to determine the effect of supplementing turkey diets with chromium propionate (Cr Prop) on Cr concentrations in tissues consumed by humans. Nicholas White male day-old poults were used in this study. Treatments consisted of 0, 0.

Chromium propionate increases insulin sensitivity in horses following oral and intravenous carbohydrate administration.

Forty-eight Quarter Horse geldings (3 to 8 yr of age) were used to determine the effects of dietary chromium (Cr), in the form of Cr propionate (Cr Prop) on insulin sensitivity. Horses were blocked by age, body condition score, and glucose response to concentrate feeding on day 0 and randomly assigned to treatments. Treatments consisted of 0, 2, 4, or 8 mg Cr/d from Cr Prop.

Chromium propionate in broilers: human food and broiler safety.

Chromium propionate (Cr Prop) is approved by the U.S. Food and Drug Administration Center for Veterinary Medicine for supplementation to broiler diets up to 0.

Testicular cavernous hemangioma associated with testicular torsion - case report and review of literature.

Introduction: Testicular neoplasms that are derived from connective tissue, blood vessels and musculature are uncommon and intra-testicular tumors of vascular origin are extremely rare; both are benign in nature. Testicular hemangioma is exceedingly rare and typically occurs in patients younger than 20 years, the age in which a primary germ cell tumor of the testis may present, necessitating a radical approach to management with orchidectomy, although potential conservative focal partial surgical excision is desirable. Hemangiomas of the testis have a similar sonographic and magnetic resonance imaging appearance to that of malignant tumors of the testis, especially seminoma.

Chromium concentrations in ruminant feed ingredients.

Chromium (Cr), in the form of Cr propionate, has been permitted for supplementation to cattle diets in the United States at levels up to 0.50 mg of Cr/kg of DM since 2009. Little is known regarding Cr concentrations naturally present in practical feed ingredients.

Chromium propionate in broilers: effect on insulin sensitivity.

The objective of this study was to evaluate the effects of dietary chromium (Cr), as chromium propionate, on measures of insulin sensitivity. Liver and muscle glycogen, and plasma glucose and non-esterified fatty acid (NEFA) concentrations were used as indicators of insulin sensitivity. In total, 288 newly hatched male Ross broilers were divided into 4 dietary treatments consisting of 0 (control diet analyzed 0.

Chromium propionate enhances insulin sensitivity in growing cattle.

Thirty-six Angus and Angus×Simmental heifers, averaging 291 kg, were used to determine the effects of dietary Cr, in the form of Cr propionate (Cr Prop), on glucose metabolism and serum insulin concentrations following glucose administration. Heifers were stratified by body weight (BW) within a breed and randomly assigned to treatments. Treatments consisted of 0, 3, 6, or 9 mg of supplemental Cr/d from Cr Prop.

Effects of supplementing dairy cows with chromium propionate on milk and tissue chromium concentrations.

Eight primiparous and 8 multiparous Holstein cows were used to determine the effects of Cr supplementation, in the form of Cr propionate (Cr Prop), on milk and tissue Cr concentrations. Cows were randomly assigned by parity to one of 2 diets: 1) control diet or 2) 2 mg of supplemental Cr/kg of DM. The level of Cr Prop supplemented exceeded by 4-fold the concentration of 0.

[Laparoscopic surgical procedures in children with the Hirschprung's disease--initial experience].

Laparoscopically assisted resection of the large intestine in the Hirschprung's disease patients was introduced into practice worldwide in mid 90-ies of the last century. In the Czech Republic this procedure had not been conducted. The aim of this work was to introduce the method in the Czech Republic.

[Endoscopic investigations in children under 3 years of age at the clinic of paediatric surgery].

Background: Retrospective study of gastroscopic investigations in children under 3 years of age.

Methods And Results: Since 1.1.

[Percutaneous endoscopic gastrostomy in children].

Aim: The authors evaluate their experience with percutaneous endoscopic gastrostomy in children at the age of three months to 14 years.

Cohort: Forty three patients treated with this method in the years 1995-2002.

Methods: The percutaneous endoscopic gastrostomy is applied in children under general anesthesia.

[Laparoscopic surgery of the spleen in children].

Laparoscopic operations of the spleen, incl. splenectomy, are increasingly accepted worldwide. The most frequent indications for this type of surgical treatment are haematological diseases (some types of haemolytic anaemia, thrombocytopenia, myeloproliferative syndrome).

[The importance of laparoscopy in children].

The authors submit the evaluation of 720 laparoscopic operations performed at the Clinic of Child Surgery and Traumatology in Brno between the end of 1994 and May 1999. The group is formed by children aged 3 weeks to 18 years. The mean age was 8.

[An unusual esophageal stenosis].

In the submitted case-history the authors describe the case of a child operated after delivery on account of oesophageal atresia type Vogt IIIb. After a two-year interval the child returned on account of acute dysphagia and endoscopy revealed oesophageal stenosis caused by a mucosal strangulating bridge. The latter was removed endoscopically and during a check-up examination 6 months later the endoscopic picture was negative.

[Transcutaneous anorectal sphincteromyectomy--possible use in pediatric anorectal surgery].

Anorectal sphincteromyectomy (SME) is a simple operation: after accurate localization of the inner anal sphincter from the latter a longitudinal strip 3-4 cm long and 2-4 mm wide is resected, depending on the child s age. In the submitted paper the author describes the surgical method which is used less frequently although it gives comparable results, it is simple and the number of complications is minimal.

[The first 100 laparoscopic procedures in children].

Laparoscopic operations (LO) of adults are performed as a routine in many departments, while LO in children are only at their onset. During September 1994 to May 1995 at the Clinic of Paediatric Surgery and Traumatology in Brno the first 100 LO and two thoracoscopic operations were performed. The group is formed by children aged 3 to 17 years.
