AIM:To examine the relationship between the trends in food consumption and gastric cancer morbidity in Poland.METHODS:The study was based on gastric cancer incidence rates and consumption of vegetables,fruit,vitamin C and salt in Poland between 1960 and 2006.Food consumption data were derived from the national food balance sheets or household budget surveys.Spearman correlation coefficients were used to estimate the relationship between the variables.RESULTS:A negative correlation was found between vegetables(-0.70 both for men and women;P < 0.0001),fruit(-0.65 and-0.66;P < 0.0001) and vitamin C(-0.75 and-0.74;P < 0.0001) consumption and stomach cancer incidence rates.The same applied to the availability of refrigerators in the household(-0.77 and-0.80;P < 0.0001).A decline in these rates could also be linked to reduction in salt intake.CONCLUSION:The decline of gastric cancer incidence probably resulted from increased consumption of vegetables,fruit and vitamin C and a decrease in salt consumption. 展开更多

A 56-day feeding trial was performed to evaluate the effects of dietary probiotic Clostridium butyricum(CB) on intestine digestive and metabolic capacities, intestine short-chain fatty acids(SCFA) content and body composition of kuruma shrimp Marsupenaeus japonicus. Shrimp s were randomly allocated into 9 tanks, 30 each, and f ed with diets containing different levels of C. butyricum(1×10~9 cfug^(-1)): 0 mgg^(-1) feed(Control), 100 mgg^(-1) feed(CB-100), 200 mgg^(-1) feed(CB-200), while each level was triplicated. The results indicated that compared with the control group, the intestine pepsin(Pep) activity and 5-hydroxytryptamine(5-HT) concentration of two C. butyricum group s were both increased. Amylase(AM Y) and lipase(LPS) activities wer e only induced in CB-200 group. Alanine aminotransferase(ALT) and aspartate aminotransferase(A ST) activities of two C. butyricum group s showed no significant change. The α-amylase(AM Y) gene expression was induced in CB-200 group, and tryp sin gene expression of two C. butyricum treated group s were both induced. Intestine SCFA content and body composition analysis showed that the contents of propionic acid, butyric acid and the crude protein of two C. butyricum group s were all higher than those of control. These results revealed that C. butyricum can modulate intestine digestive and metabolic capacities, improve intestine SCFA content and body crude protein content in M. japonicus. 展开更多

Juvenile silver pomfret, Pampus argenteus, was grown in culture tanks for 9 weeks on four different diets, and their effects on fish growth, digestive enzyme activity, and body composition were assessed. The feeding regime was as follows: Diet 1: fish meat; Diet 2: fish meat+artificial feed; Diet 3: fish meat+artificial feed+Agamaki clam meat; Diet 4: fish meat+artificial feed+Agamaki clam+copepods. The greatest weight gain was associated with Diet 4, while the lowest weight gain was associated with Diet 1. No significant difference was observed in weight gain between fish receiving Diet 2 and Diet 3. Specific growth rate followed similar trends as weight gain. The feed conversion ratio (FCR) of fish fed Diet 1 was significantly higher than the other fish groups, but no significant differences were observed in FCRs of fish fed Diet 2, Diet 3 or Diet 4. There was also no significant difference in the hepatosomatic index (HSI) between the four diets. For fish that received Diets 2-4, containing artificial feed, higher protease activities were detected. A higher lipid content of the experimental diets also significantly increased lipase activities and body lipid content. No significant differences in amylase activity or body protein content were found between Diets 1-4. In conclusion, a variety of food components, including copepods and artificial feed, in the diet of silver pomfret significantly increased digestive enzyme activity and could improve growth performance. 展开更多

Eight goats of 7-8 months old and an average body weight (BW) of 20 ± 5.0 kg were used in double 4 × 4 Latin square design. The treatments were the four levels of leucaena meal replacement for soybean meal in concentrates at 0%, 25%, 50% and 75% of crude protein. The results showed that roughage intake (% BW and g/kgBW^0.75) increased linearly (P 〈 0.01) with increasing levels of leucaena meal while total feed intake was not significantly different among dietary treatments. Similarly, dry matter, organic matter, neutral detergent fiber digestibility and ruminal ammonia nitrogen (NH3-N) were not significantly different among dietary treatments. However, crude protein digestibility, ruminal pH (6 hr after feeding), nitrogen (N) intake, N absorption, N retention and total volatile fatty acids increased quadratically (P 〈 0.01) with the increasing levels of leucaena meals. It could be concluded that leucaena meal could replace up to 50% of soybean meal in the diet without any negative effect on feed intake, nutrient digestibility and rumen fermentation of meat goats. 展开更多

The objective of this study was to evaluate the effect of high digestible essential amino acids (DEAA) on weight gains and carcass compositions of laying hens. Three hundred and sixty lsa Brown hens in five replications per treatment (12 birds/replicate) were used. Six experimental diets which contained of treatment 1 (negative control) as the conventional layer diet are recommended by NRC (1994) while another dietary treatments; treatments 2 (positive control), 3, 4, 5 and 6 were formulated to meet 100%, 110%, 120%, 130% and 140% of Standard Ileal Digestible Lysine Levels (SIDLL) without crude protein minimum, while methionine (Met), threonine (Thre) and tryptophan (Tryp) as related by Ideal Protein Concept (IPC) which suggested by NRC (1994) and INRA (2004). However, metabolizable energy (ME), calcium and available phosphorus (Avai P) levels of all experimental diets were meet requirement as recommended by NRC (1994). The experiment was assigned in CRD and laying hens fed dietary treatments from 28 to 44 weeks of age and cage was the experimental unit (3 hens/cage). The result shown that percentages of thigh (TP), feet (FP), drumstick (DP), heart (HP), liver (LP) and gizzard (GP) were not affected by dietary treatment. However, weight gains (WG) and percentage of dressed weight (DWP), eviscerate weight (EWP) and breast (BP) were increased (P 〈 0.05) and abdominal fat was reduced (P 〈 0.05) when birds fad diets containing 130% of SIDLL as compared with control group and another dietary treatments, when increasing the DEAA levels upper to 130% of SIDLL. The result indicated that diets formulated without crude protein minimum and increased DEAA resulted in increasing the efficiency of converting metabolizable energy (ME) to net energy (NE) for increasing weight gain and improved meat products while fat deposition in carcass composition was reduced. 展开更多

The new Nordic diet (NND) was designed by gastronomic, nutritional and environmental specialists to be a palatable, healthy and sustainable diet containing 30%-40% less meat than the average Danish diet (ADD), ≥ 75% organics, and more locally grown wholegrain products, nuts, fruit and vegetables. In this study, the NND was based on economic modelling to represent a "realistic NND bought by Danish consumers". The objective was to investigate whether the ADD-to-NND diet-shift has environmental consequences that outweigh the increased consumer cost of the diet-shift. The diet-shift reduced the three most important environmental impacts by 16%-22%, mainly caused by reduced meat content. The surcharge to consumers of the ADD-to-NND diet-shift was ∈216/capita/year. In monetary terms, the savings related to the environmental impact of the diet-shift were ∈151/capita/year. 70% of the increased consumer cost of the ADD-to-NND diet-shift was countered by the reduced socioeconomic advantage associated with the reduced environmental impact of the NND. 展开更多

The study was conducted to investigate the effects of feeding high-fiber diet (HFD) on apparent total tract digestibility (ATTD) and absorption of minerals in growing pigs. Sixteen barrows averaging 16.39 kg were randomly assigned to one of four diets after metabolic crate assignment with individual pig serving as experimental unit. Diets include: a corn-soybean meal based low-fiber diet (LFD), as the control (CON) and 3 HFD (D1, D2 and D3), each containing 5% sugar beet pulps and a 1:2, 1:1 and 2:1 oats to barley ratios, respectively, replacing 47% of the corn in the diet. Diets were formulated to meet nutrient requirements, however, the fiber content of the LFD was substantially lower than the average of the HFD (8.38% vs. 22.40%). Feed allowance was limited to 10% of average body weight and fed twice/d. The study period was divided into 10 d of adjustment and 5 d of feces collection. Data collected were analyzed using SAS, GLIMMIX procedure where animals were considered random effects, and minerals were fixed. Results of the study show that digestibility of Ca in pigs fed HFD was lower (P 〈 0.05) than in pigs fed LFD. On the other hand, the apparent digestibility of P, K, Na, S and Zn in pigs fed D2 and D3 were higher (P 〈 0.05) than in pigs fed CON diet. It was also observed that digestibility of Ca, P, K, Na, S and Zn in pigs fed D1 were lower (P 〈 0.05) than in CON, D2 or D3 fed pigs. Therefore, it was concluded that while feeding HFD reduced availability of Ca, the availability of P, K, Na and S to pigs improved as the oat to barley ratio in the diet increased. 展开更多
