The effects of dietary fat or fructose supplementation during late gestation and lactation on sow milk production and composition and on progeny were examined. On d 88 of gestation, 24 sows were allotted by parity to three dietary treatments (eight sows/treatment). Treatments were 1) a 12.5% crude protein, corn-soybean meal control, 2) the control + 10% added fat or 3) the control + 23% high fructose corn syrup. All treatments were fed to supply 1.82 kg/d of the control diet from d 89 of gestation to parturition with sows in treatments 2 or 3 receiving .18 kg of additional fat or .53 kg of additional high fructose corn syrup, respectively. Feed was gradually increased from d 1 to 7 of lactation to 4.54 kg/d of the control diet (plus .45 kg of added fat and 1.33 kg of added fructose for treatments 2 and 3) and remained at these levels for the remainder of the 21 d lactation period. All treatments were iso-nitrogenous; treatments 2 and 3 were iso-caloric. Litter birth weights, number of pigs born alive, weaning weights and piglet survival rate were not affected by sow treatment. Stillbirths were less (P less than .05) for sows fed fat. Lipid content of milk 24 h post-farrowing was greater (P less than .05) from sows fed fat compared with sows fed fructose. Milk production estimates indicated that multiparous sows fed fat produced more (P less .05) milk than sows fed the control diet. On d 112 of gestation and d 15 of lactation, serial blood samples were drawn to monitor sow response to a glucose challenge (1 g/kg body weight).(ABSTRACT TRUNCATED AT 250 WORDS)
The effect of feeding various levels of dietary fructose, furnished by high fructose corn syrup (HFCS), to broiler-type chicks housed in Petersime batteries was studied in two experiments. In experiment 1, HFCS was added to a corn-soybean meal basal diet at levels of 0, 5, 10, and 15%. In Experiment 2, HFCS was added to the diet at levels of 0, 2, 4, 6, and 15%. In both experiments diets were isocaloric and isonitrogenous. In Experiment 1, chicks fed HFCS consumed more feed (P less than or equal to .05) and grew more rapidly (P less than or equal to .05) than chicks fed the control diet. No differences in the feed to gain ratio were observed among treatments. Feeding HFCS resulted in non-significantly higher liver weight and percent liver lipid. Values for kidney weights and plasma uric acid were higher (P less than or equal to .05) in chicks fed 15% HFCS. In Experiment 2, adding 4, 6, and 15% HFCS resulted in more rapid growth (P less than or equal to .05). No significant differences were observed in feed intake and kidney weights. Chicks fed the 15% HFCS diet had heavier (P less than or equal to .05) livers.
Citrus black spot is an emerging fungal disease that affects Florida citrus. Various symptom types occur about a month before harvest. Black spot has the potential to cause major economic damage to the fresh fruit industry and significant yield loss on processing varieties. This trifold brochure was written by Megan Dewdney and Jamie Yates, and published by the UF Department of Plant Pathology, January 2011. *Jamie Yates' name has changed to Jamie Burrow PP281/PP281: Citrus Black Spot: No Longer an Exotic Disease... A Manageable Disease in the Florida Citrus Industry (ufl.edu)
