Mineral balance of finishing pigs fed copper sulfate or a copper-lysine complex at growth-stimulating levels.

Abstract: Twenty-four crossbred barrows (average BW, 70.8 kg) were used to compare the digestibility of dry matter and the mineral absorption and retention by pigs fed two Cu sources. Dietary treatments were 1) basal (B) (16% CP corn-soybean meal-based diet, 36 mg/kg of Cu), 2) B + 200 mg/kg of Cu from CuSO 4 .5 H 2 O (CuSO 4 ), and 3) B + 200 mg/kg of Cu from a copper lysine complex (CuLys). All diets contained equal lysine content and.05% chromic oxide for indirect determination of absorption. Two 7-d total collection periods were conducted. Pigs were fed 8% of metabolic BW (BW .75 ) divided into two equal feedings. Average daily gain tended to be higher for pigs fed CuLys than for pigs fed CuSO 4 (P .10) among treatments. The absolute amount of Cu absorbed and retained was greater for pigs fed both Cu sources (P .10) among treatment groups. Chromium intake and excretion in feces were not different (P >.10), with an average recovery of 93.8%. Indirect DM digestibility was similar to total collection values ; however, mineral values were similar only after correction for Cr recovery. Pigs fed elevated Cu absorbed more Cu, with no difference between the two sources. Zinc and Fe absorption and retention were generally not affected (P >.10) by Cu addition or sources. The absorption and retention of Cu was similar for pigs fed growth-stimulative levels of Cu from CuSO 4 or copper lysine complex.

The effects of isomaltulose, isomalt, and isomaltulose-based oligomers on mineral absorption and retention

Abstract: We carried out a balance study to examine the effects of isomaltulose, lactose, isomalt, and isomaltulose-based oligomers (IBOs) on mineral (calcium, magnesium, phosphorus, and iron) absorption and retention Four-week-old male Wistar rats were divided into five groups of six rats each and fed a basal diet or diet the containing either 5% isomaltulose, 5% lactose, 5% isomalts or isomaltulose-based oligomers (IBOs) ad libitum for 16 d After 1 wk, the animals were subjected to a 5-d mineral (calcium, magnesium, phosphorus, and iron) balance study The isomalt feeding, as well as the IBOs feeding, led to significantly elevated mineral absorption and retention On the other hand, lactose feeding, widely known to enhance calcium absorption, increased only calcium absorption and isomaltulose feeding did not affect mineral absorption or retention The organic acids in cecum contents were increased by IBOs or isomalt feeding Succinic and acetic acids in cecum contents were significantly increased by IBOs feeding Similarly, succinic, acetic, and i-valeric acids and total amount of organic acid in cecum content were significantly increased by isomalt feeding Although the organic acids in cecum contents were increased by IBOs or isomalt feeding, the pH values and acidity in cecum contents were not changed by IBOs or isomalt feeding The effect of addition of various organic acids to the mucosal fluid was examined with in vitro study using a hindgut segment By the addition of acetic acid, and butyric acid, the mineral (calcium, magnesium, and phosphorus) uptake was increased

Mineral absorption accelerating agent

Abstract: PROBLEM TO BE SOLVED: To obtain a mineral absorption accelerating agent containing cells of a bacterium belonging to the genus Bifidobacterium as an active ingredient, having an accelerating action on the increase of a bone strength and a bone mineral content, and useful for the prevention and treatment of osteoporosis. SOLUTION: This mineral absorption accelerating agent contains cells of a bacterium belonging to the genus Bifidobacterium such as Bifidobacterium longum, B. bifidum, B. adolescentis, B. breve and B. infantis, as an active ingredient and e.g. by 1×10 to 1×10 /g number of cells as live cells. These cells are obtained by inoculating the prescribed cells to a liquid medium for propagation such as Brigg's liver broth, culturing under an anaerobic condition, at 37 deg.C for 16hr, then collecting cells by a centrifugal separation, washing and lyophilizing. Further, preferably this medicine is taken by >=1×10 cells daily in the case of an adult.

Promoter of mineral absorption, and mineral nutrient

Abstract: PROBLEM TO BE SOLVED: To obtain a promoter of mineral absorption having activities promoting the absorption of calcium and magnesium supplied from exterior to the interior of the body, and useful for treating and preventing osteoporosis by including a fermented material by using lactic acid bacteia. SOLUTION: This promoter of mineral absorption includes a fermented material by using lactic acid bacteria belonging to genus lactobacillus, preferably Lactobacillus casei, and/or the one belonging to genus streptococcus, preferably Streptococcus thermophilus. The promoter can includes a dried powder, etc., obtained by using the fermented material as a raw material, as an active ingredient. Further the promoter can have a form of a fermented milk such as yogurt, or can be prepared as a composition containing ≥10% of the fermented material expressed in terms of solid.

Digestibilidade (aparente) de sucedâneos do leite com bezerros

Abstract: Eight calves were used in a digestibility assay, to evaluate digestibilities and mineral absorption rates of four milk replacers, used as only feed sources, and varying according to the nature of their protein: (A) 100% of digestible protein from milk, (B) 20% of Digestible Protein as Soybean Protein Concentrate, (C) 40% of Digestible Protein as Soybean Protein Concentrate and (D) 60% of Digestible Protein as Soybean Protein Concentrate. The apparent Digestibility Coefficient for Dry Matter, Crude Protein and Ash absorption were: (A) 87.63, 85.39 and 69.97%; (B) 83.73, 79.82 and 52.54%; (C ) 80.95, 71.37 and 65.35% and (D) 75.7, 69.03 and 42.86%, respectively, with significant linear regression effect (p < 0.01), (p < 0.05) and (p < 0.05). No differences among treatments were observed for diarrhea incidences.
