Effects of sources and routes of administration of vitamins A, D and copper on postnatal status of these micronutrients in piglets.

Twenty-six nulliparous sows were fed conventional gestation and lactation diets supplemented ( = 13) or not ( = 13) with extra daily supplements of 25-hydroxy-cholecalciferol (25-OH-D3; 4 ĸIU), β-carotene (24 ĸIU), and copper ()-proteinate (45 mg) from day 90 of gestation to 21 d of lactation (). In each litter, 10 piglets were divided into 5 pairs received, at 2 () and 8 d () of age, one of the five combinations of micronutrient sources and routes of administration ( = 260 piglets total). These neonatal treatments (= 26 pairs or 52 piglets each) consisted of oral vitamin D3, retinol acetate and CuSO (); oral 25-OH-D3, β-carotene, and Cu proteinate (); exposure to ultraviolet light (), oral retinol palmitate and Cu gluconate (); intramuscular vitamin D3 and retinyl propionate and oral Cu acetate (); oral saline ().

Effects of high levels of zinc oxide and dietary zinc/copper ratios on the metabolism of iron in weaned pigs.

The present study compares the use different levels of dietary zinc oxide and zinc/copper ratios on the metabolism of iron (Fe) in weaned pigs. Two experiments were conducted using 120 and 160 weanling piglets (7.96 ± 1.

Improving implementation of best practices in obesity management: Physician experiences in obesity care.

In this study, we sought to analyse experiences in weight management among physicians working in the area of obesity and contrast these experiences with best practices. By understanding experiences of physicians working in obesity management, we can better support implementation of best practices in their day-to-day practice. An online survey of Canadian primary care physicians, internists and endocrinologists recruited from a nationwide market research database was conducted.

Effects of dietary zinc/copper ratios on the metabolism of zinc and copper in weaned pigs.

This study compared the effects of different dietary zinc/copper ratios on zinc (Zn) and copper (Cu) metabolism in weaned pigs. One hundred and sixty piglets (7.81 ± 0.

Effects of dietary zinc oxide levels on the metabolism of zinc and copper in weaned pigs.

This study compared different dietary zinc oxide (ZnO) levels on zinc (Zn) and copper (Cu) metabolism in weaned pigs. One hundred twenty weaned piglets (7.96 ± 1.

Impact of dietary zinc:copper ratio on the postprandial net portal appearance of these minerals in pigs1.

The present study compared the net intestinal absorption of zinc (Zn) and copper (Cu) after meals containing different dietary ratios among these trace elements. Ten 46-kg pigs were used in a cross-over design to assess the 10-h net portal-drained viscera (PDV) flux of serum Cu and Zn after ingestion of boluses containing ZnSO4 and CuSO4 in different Zn:Cu ratios (mg:mg): 120:20; 200:20; 120:8; and 200:8. Arterial Zn concentrations peaked within the first hour post-meal and responses were greater with 200 (0.

Bioavailability of Vitamin B from Dairy Products Using a Pig Model.

The present study compares the bioavailability of vitamin B (B) of dairy products or synthetic B, using the pig as an experimental model for humans. Eleven pigs were used in a cross-over design to assess the net portal drained viscera (PDV) flux of blood plasma B after ingestion of tofu (TF; devoid of B), Swiss cheese (SC), Cheddar cheese (CC), yogurt (YG), and synthetic B (TB; TF supplemented with cyanocobalamin), providing a total of 25 µg of B each. PDV blood plasma flow for SC and CC were higher than for TF and TB ( ≤ 0.

The importance of pyridoxine for the impact of the dietary selenium sources on redox balance, embryo development, and reproductive performance in gilts.

This study aimed to determine the effects of dietary pyridoxine and selenium (Se) on embryo development, reproductive performance and redox system in gilts. Eighty-four gilts were fed one of five diets: CONT) basal diet; MSeB60) CONT+0.3mg/kg of Na-selenite; MSeB610) diet 2+10mg/kg of HCl-pyridoxine; OSeB60) CONT+0.

Interaction between vitamin B6 and source of selenium on the response of the selenium-dependent glutathione peroxidase system to oxidative stress induced by oestrus in pubertal pig.

This study aimed to assess the interaction between vitamin B6 and selenium (Se) for the flow of Se towards the Se-dependent glutathione peroxidase (GPX) system in response to oxidative stress naturally induced by oestrus in a pubertal pig model. At first oestrus, forty-five gilts were randomly assigned to the experimental diets (n=9/group): basal diet (CONT); CONT+0.3mg/kg of Na-selenite (MSeB60); MSeB60+10mg/kg of HCl-B6 (MSeB610); CONT+0.

Fish oil diets alter the phospholipid balance, fatty acid composition, and steroid hormone concentrations in testes of adult pigs.

The objective was to determine the effect of long-term dietary supplementation of two types of fish oil on lipid composition and steroidogenesis in adult pig testis. Twenty-four Duroc boars, aged 204.5 ± 9.

Fish oil diets do not improve insulin sensitivity and secretion in healthy adult male pigs.

The effects of long-term dietary supplementation of fish oil (n-3 PUFA-rich) in adult male pigs on body condition as well as insulin sensitivity and secretion were examined. Fifteen Duroc boars aged 204.5 (sd 9.

Breast conservation surgery using nipple-areolar resection for central breast cancers.

Hypothesis: Resection of the nipple-areolar complex (NAC) for central breast cancers that involve the nipple or areola, with postoperative radiation therapy, adheres to the oncologic principles established for breast conservation surgery of other breast cancers. Good or excellent cosmetic results can be achieved. The rate of ipsilateral breast recurrence will be similar to that seen with peripheral breast cancers.
