Effects Of Milk Replacer And Multivitamin-Mineral Supplementation On Performance Of Heat Stressed Dairy Calves, Steven Joseph Blair
Effects Of Milk Replacer And Multivitamin-Mineral Supplementation On Performance Of Heat Stressed Dairy Calves, Steven Joseph Blair
LSU Master's Theses
Seventy-one Holstein calves were used to evaluate the effects of milk replacer (MR) feeding management alone or in combination with a multivitamin-electrolyte supplement on growth and mitigation of heat stress. Milk replacer treatments consisted of Land O’Lakes Herdmaker Supreme (20% CP, 20% fat) and Land O’Lakes Warm Front (27% CP, 10% fat). Calves received either 0 or 20 ml Palamountains Calf Boost® in MR once daily. Calves were offered treatments beginning on day 4. Calves on 27% CP : 10% fat MR were fed 2.72kg MR twice daily for the first three weeks of life, and 3.86kg twice daily until …
Effects Of Feeding Milk Replacer Once, Twice Or Three Times Daily On Growth And Performance In Neonatal Holstein Calves, Michael Thomas
Effects Of Feeding Milk Replacer Once, Twice Or Three Times Daily On Growth And Performance In Neonatal Holstein Calves, Michael Thomas
LSU Master's Theses
Sixty-three neonatal Holstein calves (45 female; 18 male) were assigned to one of 3 treatments at d 2 of age to study effects of milk replacer feeding frequency on growth, performance, and health. Treatments consisted of 1X, with total amount of reconstituted milk replacer fed 1X/day at 6:00 a.m.; 2X, with total amount of reconstituted milk replacer divided into 2 equal amounts and fed at 6:00 a.m. and 5:00 p.m.; or 3X, with total amount of reconstituted milk replacer divided into 3 equal amounts and fed at 6:00 a.m., 12:00 noon, and 5:00 p.m. Calves were housed in individual hutches …
Effects Of Meal Timing On Growth Hormones, Ghrelin, And Insulin Sensitivity In Male Holstein Calves, Erica Lynn Chartier
Effects Of Meal Timing On Growth Hormones, Ghrelin, And Insulin Sensitivity In Male Holstein Calves, Erica Lynn Chartier
LSU Master's Theses
Eighteen neonatal Holstein bull calves (38.85 ± 4.71 kg) were assigned to one of two treatments at birth to determine the effect of feeding time on growth, nutrient intake, metabolic hormone secretion, and energy metabolism. Regularly fed calves (n = 9) were fed MR daily at 0630 h, and irregularly fed calves (n = 9) at 1030, 0800, 0630, 0830, 0530, 0930, and 0730 Monday through Sunday. Body weights were measured weekly from birth to 9 weeks. Water intake, fecal scores, and starter intake were measured daily. Serial blood collections were conducted at 2, 4, 6, and 8 weeks for …
Effects Of Resistant Starch In Milk Replacer On Health And Performance In Neonatal Holstein Heifer Calves, Bethany Leann Fisher
Effects Of Resistant Starch In Milk Replacer On Health And Performance In Neonatal Holstein Heifer Calves, Bethany Leann Fisher
LSU Master's Theses
Forty-two female Holstein calves were assigned to one of three treatments at d 2 of age to study the effects of adding resistant starch (RS) to the milk replacer on health and performance. Treatments were control (0g RS), 4g RS, or 8g RS mixed into the reconstituted milk replacer. Calves were housed in individual calf hutches and fed milk replacer once daily until d 42 of age. Water and an 18% crude protein calf starter were offered ad libitum beginning d 3 throughout the duration of the 56 d trial. Calves remained in their hutches until d 56 of age …
Prepartum Maternal Cortisol Concentrations On Postnatal Cortisol Concentration And Immunoglobulin Absorption In Neonatal Dairy Calves, Dana Nadine Wooley
Prepartum Maternal Cortisol Concentrations On Postnatal Cortisol Concentration And Immunoglobulin Absorption In Neonatal Dairy Calves, Dana Nadine Wooley
LSU Master's Theses
The role of glucocorticoids on intestinal closure in neonates has recently become an area of interest but a definitive mechanism remains to be identified. It is known that glucocorticoids enhance immunoglobulin absorption in dairy calves, but the role of maternal glucocorticoids at parturition is not clear. In the present experiment, we obtained plasma and milk samples from primiparous and multiparous Holstein cows (n=24) to measure cortisol at 72, 48 and 24 hours before and 3, 6, 12, 24 and 48 hours after spontaneous parturition. After parturition, calves (n=24) were immediately removed from their dams and a blood sample was taken …
Effects Of Varying Levels Of Cottonseed Hulls On Growth And Metabolic Indications Of Rumen Development Of Dairy Calves, Ryan Doescher
Effects Of Varying Levels Of Cottonseed Hulls On Growth And Metabolic Indications Of Rumen Development Of Dairy Calves, Ryan Doescher
LSU Master's Theses
A study was conducted to determine the effects of varying levels of cottonseed hulls on growth and metabolic indications of rumen development of dairy calves. Sixty-four Holstein calves (Heifers, n=40; Bulls, n=24) were randomly assigned to one of four dietary treatments which included calf starters containing no cottonseed hulls (control; C), 10% cottonseed hulls (10% CSH), 15% cottonseed hulls (15% CSH), or 20% cottonseed hulls (20% CSH). Calves were fed their respective treatments beginning on day 6 until day 56 of age. Body weights were measured at birth and biweekly thereafter until day 56 of age. Wither and hip heights …
Effects Of Meal Timing On Anabolic Hormone Status And Energy Metabolism In Neonatal Dairy Calves, Katherine Claire Simon
Effects Of Meal Timing On Anabolic Hormone Status And Energy Metabolism In Neonatal Dairy Calves, Katherine Claire Simon
LSU Master's Theses
Twelve neonatal Holstein bull calves (38.52 ± 5.87 kg) were fed milk replacer at a fixed or varied meal time to determine the effects on metabolic hormone secretion, average daily intake, growth, and energy metabolism. Body weights were measured every two weeks from birth to 8 weeks. Rumen fluid was collected every two weeks from week 2 through 8. Serial blood collections were conducted every two weeks from week 2 through 8. Blood was collected, beginning at 0530, at 0, 15, 30, 45, 60, 75, 90, 105, 120, 135, and 150 minutes. Plasma was analyzed for ghrelin, leptin, growth hormone …
