In the first trial, 64 one‐week‐old male broiler chicks were fed ad libitum in four dietary treatment groups for a 6‐week period. Experimental mash diets were prepared by mixing a maize‐soybean based standard broiler starter or finisher with tap water in the ratios of 0.0: 1.0, 0.5: 1.0, 1.0: 1.0 and 1.5: 1.0 (water: air‐dry feed, w/w). More water in the diet increased BWG, DMI, abdominal fat and carcass weight, carcass CP, crude fat, but it deteriorated DM conversion efficiency. In the second experiment, 64 one‐week‐old male broiler chicks were given air‐dry or wet (waterfeed, 1.5: 1) starter or finisher diets without or with ascorbic acid supplementation (0 and 250 mg/kg air‐dry feed, resp.) ad libitum for a 6‐week period. Ascorbic acid supplementation increased BWG, carcass weight and carcass CP significantly, while reducing carcass crude fat content. However, feeding broilers with a diet mixed with water in a ratio of 1.5: 1.0 increased BWG, DMI, carcass weight and carcass lipid markedly, but deteriorated DM conversion efficiency. There was also a significant interaction between ascorbic acid and wet feeding, whereby ascorbic acid supplementation induced a significant reduction in carcass lipid contents of broilers fed on air‐dry diets but not on wet diets. It is concluded that wet feeding, especially an addition of 150% water to produce a porridge like consistency, improved growth performance by increasing fat, ash and protein deposition in the body, while reducing DM conversion efficiency. It is also concluded that under heat stress supplemental ascorbic acid in air‐dry diets stimulates broiler performance but not in wet diets.","PeriodicalId":8141,"journal":{"name":"Archiv für Tierernaehrung","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83110883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Latin square experiment was carried out with 4 horses and 4 dietary treatments. The experimental periods lasted 21 d. Blood samples were taken 16 h after feeding. The diets consisted of hay and experimental concentrates, differing in fat source (MCT or soybean oil) and carbohydrate source (corn starch plus glucose or cellulose). The dietary variables, MCT or soybean oil, provided on average 27% of total dietary net energy, while glucose plus cornstarch or cellulose provided 33%. The feeding of MCT versus soybean oil raised the level of plasma triacylglycerols significantly from 196.7 ± 30.2 to 427.3 ± 85.7 mmol/1 and that of VLDL cholesterol from 0.028 ± 0.01 to 0.069 ± 0.01 mmol/ml. As based on analysis of variance, for the four experimental diets there was no significant effect of carbohydrate source and no fat‐carbohydrate interaction. Thus, the hypothesis was rejected. When the diets contained soybean oil, cellulose versus starch plus glucose produced significantly greater increase plasma triacylglycerols. This carbohydrate effect was not seen when horses were fed the MCT diets. The experimental concentrates did not differently influence the concentrations of plasma glucose, total serum cholesterol, phospholipids, insulin, free fatty acids and the activity of post‐heparin lipoprotein lipase. We suggest that the MCT‐induced increase in plasma triacylglycerols is related to an increase in hepatic VLDL secretion, with the extra substrate for increased synthesis of triacylglycerols being the acetyl‐CoA derived from the hepatic oxidation of medium chain fatty acids.","PeriodicalId":8141,"journal":{"name":"Archiv für Tierernaehrung","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81516150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two hours after feeding, significantly higher arabinose and xylose concentrations were present in the stomach for diets Cel‐i, Cel‐a and Xyl‐i. In the ileum xylose and arabinose concentrations were higher 2 to 4 and 6 to 8 hours after feeding the enzyme‐treated diets. In stomach and ileum there were no differences between the diets in pH, osmolality, VFA and lactic acid concentrations, but ileal VFA concentration from 4 h after feeding tended to be higher for diets Cel‐i and Xyl‐i.

Three basal diets, marginally deficient in dietary P mainly provided as phytate, were formulated. Both phytases were added to the diets at the rate of 500 U/kg diet. The phytases significantly (P ≤ 0.05) improved the availability of phytate P to broilers, layers and young pigs. Aspergillus and E. coli phytases enhanced the pre‐caecal digestibility of P by 11 and 29% for broilers and 18 and 25% for layers, respectively. Total tract digestibility of P (P balance) was also enhanced but with smaller magnitude. In pigs, total tract digestibility of P was improved by 33 and 34% by Aspergillus and E. coli phytases, respectively. Under the conditions of this study, it was observed that E. coli consistently, though with small magnitude in layers and pigs, enhanced the availability of phytate P at the same range or slightly better than Aspergillus phytase. It was only in pigs that the availability of Ca was significantly (P ≤ 0.05) improved by addition of both phytases. It can be concluded that E. coli phytase is highly effective in improving the bioavailability of phytate P to broilers, layers and young pigs. This seems to be based on the high proteolytic stability of the enzyme in the digestive tract, as shown recently.","PeriodicalId":8141,"journal":{"name":"Archiv für Tierernaehrung","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80810769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The air‐dry mango seed kernels (MSK) contained CP 70 gkg‐1, EE 128gkg‐1, and tannins 67 gkg‐1. Compared with raw kernels the contents of trypsin inhibitory activity (30 TIU g‐1) and cyanogenetic glucosides, measured as hydrocyanic acid (71 mgkg‐1), were lowered by boiling, autoclaving and radiation treatments. Tannin content (67.2 gkg‐1 in raw kernels) was decreased only by boiling or autoclaving, but irradiation did not introduce any effect. The low in vitro protein digestibility and AMEN values of raw MSK were enhanced by processing. The improvements were paralleled to reductions in trypsin inhibitory activity, cyanogenetic glucosides and tannin contents. Greater improvements were noticed with boiling and autoclaving than with irradiation alone. Autoclaving for 30 min plus irradiation treatment up to 20 kGy increased the in vitro protein digestibility and AMEN by 139% and 72%, respectively. These results indicate that tannins, trypsin inhibitors and cyanogenetic glucosides are responsible for the poor nutritive value of MSK. The effects of feeding 200 g kg‐1 raw or processed MSK on the performance of broiler chicks were examined. The inclusion of raw kernel affected body weight gain and feed consumption, while weight gain of birds fed the autoclaved (30 min) plus irradiated (20kGy) kernels was significantly more improved than by the other treatments. However, feed conversion ratio was not significantly different between groups fed the processed MSK, The results showed that the combination of autoclaving for 30 min plus irradiation up to 20 kGy upgraded the nutritive value more than the other tested treatments and that this method is most effective in processing MSK to be used as animal feed.","PeriodicalId":8141,"journal":{"name":"Archiv für Tierernaehrung","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2001-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78138507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inocula of both rumen ciliates Entodinium caudatum and Epidinium ecaudatum were used at a volume of 34 ml into the 50 ml glass syringes together with the feed and compounds tested. Despite penicillin G ‐ streptomycin treatment methane production in both cultures was significantly decreased by the inhibitors for Epidinium ecaudatum. Methane production of the bacterial fraction of both protozoan species was significantly lower than in the whole cultures. No epifluorescence of methanogens on (or in) the cells of Entodinium caudatum was observed in contrast to Epidinium with which strong epifluorescence of methanogens on the cell surface was detected. Microscopic observation could indicate that the methane production by Entodinium caudatum was probably caused by their intracellular methanogenic activity, while methane production by Epidinium ecaudatum could be related to both the methanogenic bacterial fraction from their external surface and probably also to intracellular activity. Decreased feed degradability and differences in the fermentation end products accompanied the inhibition of methanogenesis in both in vitro cultures.

Lumen samples and mucosal tissues from the hind gut of piglets displayed increasing colonization of the probiotic strain throughout the trial period. After oral administration of vegetative cells to broiler chicken and weaned piglets, sporulation was detected in all intestinal samples. The distribution of spore CFU indicated repeated germination and sporulation during the intestinal passage in piglets.
