Alteration of Milk Composition in Dairy Cows Fed Supplemental Fat
… percentage that is associated with feeding supplemental fat to lactating dairy cows. In experiment one, it was hypothesized that feeding ruminally protected methionine and lysine would alleviate this depression in milk protein. Feeding supplemental fat increased milk production and decreased …

Effects of Supplemental Fat on Beef Cow and Heifer Performance, Lactation and Reproduction
… of this research was to evaluate the effects of supplemental fat on beef cow and heifer performance, lactation and reproduction. Supplemental fat sources, differing in fatty acid composition, were evaluated to determine the effects on performance, lactation and reproduction in Angus x Simmental …

The effects of supplemental fat and methionine hydroxy analogue on cellulose digestion in wether lambs
… the effects of different levels of two types of fat on cellulose diges tion in lambs on a poor quality roughage. Methionine hydroxy analogue, the alpha keto acid of methionine, was studied to determine its effect on a low sulfur ration made up of natural feeds."--Page 2

Effects of feeding supplemental fat to cows in late gestation on cold tolerance in newborn calves
… conducted to investigate the effects of added fat in late gestation cow and heifer diets on thermogenic and neonatal metabolic responses. In Experiment 1, the effects of source of fat in late gestation diets on serum glucose and thermogenic response during short-term cold stress were examined …

Peripartal Lipid Metabolism and Tissue Fatty Acid Composition in Holstein Cows Fed Supplemental Fat During the Dry Period
… calving after attempting to add BCS by feeding fat to dry cows. Results were confounded; feeding supplemental fat to dry cows was associated with lower DMI and BCS loss. Consequently, 36 cows were fed high-grain or fat-supplemented diets to reassess the effects of feeding supplemental fat to dry …

Digestion and utilization of nutrients in diets containing feather meal and (or) supplemental fat by lactating dairy cows
… the effects of feeding feather meal and fat. The objective of Experiment 1 was to determine milk production, milk composition, feed intake, and concentrations of AA and long chain fatty acids in blood plasma. Thirty two Holstein cows began a six week trial at the start of the fourth week …

Effects of Protected Fat When Fed to Dairy Cattle and the Interaction Between Supplemental Fat and Antibiotics in Mixed Cultures.
Fat is added to diets of lactating dairy cattle as an affordable method of increasing the amount of energy available to the animals. Unsaturated fatty acids are desirable end-products of milk production. However, their presence in the rumen can be toxic to ruminal bacteria, which will then decrease …

Response of Lactating Cows to Added Unsaturated Fat and Niacin
… with 4 wk periods to evaluate the response to supplemental fat and niacin. Diets were control, control plus niacin (12 g/d), added fat, and added fat plus niacin. All total mixed diets (DM basis) contained 25% alfalfa hay, 25% corn silage, and 50% respective concentrate mixture. Supplemental …

Biohydrogenation, postruminal flow, and apparent digestibility of dietary lipids in lactating Holstein cows
… flow rates, and digestibility of dietary fatty acids in the gastrointestinal tract. In the first experiment, four cows were fed diets with 0% supplemental fat, 3% tallow, 3% partially hydrogenated tallow, or 3% tallow coated with casein and corn syrup solids. Fatty acid intake and flow to …

Effect of dietary protein degradability and fat on rumen, blood and milk components of Jersey and Holstein cows
… the effects of dietary protein degradability and supplemental fat on rumen, blood, and milk components. Diet dry matter contained 16% CP with two levels of rumen undegradable protein (RUP) obtained by substituting blood meal for soybean meal. Treatments were 29% RUP, 0% added fat; 29% RUP, 2.7% …

Characteristics of Milk and Reduced Fat Cheddar Cheese from Cows Fed Extruded Soybeans and Niacin
… are demanding food products that are "low-fat", "reduced fat", "high in -unsaturated fatty acids", and "low cholesterol". This trend in food product selection is at the advice of many health professionals. Current health recommendations are to lower the dietary intake of fat, especially …

Nutritional Management Strategies to Increase Energy Intake of Lactating Cows
… first 100 d); or increased caloric density from fat (FAT = 50:50 first 100 d). After 100 d postpartum, all cows continued on the CON diet with F: C increasing to 60:40 after production declined to < 32 kg/d ( < 25.0 kg/d for lactation 1), and to 70:30 for ≥2 lactation cows producing < 20. 5 kg/ …

Effects of Using Canola Meal as a Protein Source in Broiler Diets
… meal in broiler diets with a constant level of supplemental poultry oil. The resulting data suggested when diets are formulated with a constant level of supplemental fat; the level of CM should not exceed 10%.</p> <p>Experiment 3 and 4 were conducted simultaneously which examined two diet types …

Effects of gestation length and supplemental dietary fat on colostrum and milk composition in swine
… induced premature or delayed farrowing and supplemental dietary fat on colostrum and milk composition in the sow. The induction of premature farrowing (d 112 of gestation) was shown to affect the composition of colostrum and milk, particularly by altering the fat content. The average fat …

Postruminal flow, digestibility, and utilization of fatty acylamides or conjugated linoleic acid for milk fat synthesis by lactating Holstein cows
… were used to evaluate the effects of dietary fatty acylamides (canolamide) or abomasally infused conjugated linoleic acid on milk production and composition. In the first experiment, cows were fed diets with no supplemental fat(control), or the control diet supplemented at 3.3% of DM with …

Influence of dietary fat and protein on nutrient supply and utilization by the lactating bovine mammary gland
… of this study was to determine whether dietary fat supplementation and level of undegradable intake protein (UIP) could affect daily milk output and composition by influencing nutrient supply to the mammary gland. Three lactating Holstein cows (60, 68, and 74 d postpartum) were used in an …
