Effects Of Feeding Probiotics To Pre-Weaned Dairy Calves, Sara Tomis
Effects Of Feeding Probiotics To Pre-Weaned Dairy Calves, Sara Tomis
Honors Scholar Theses
Pre-ruminant calves are particularly susceptible to pathological and environmental stressors that may have negative effects on their health and growth. Supplementing probiotics to this vulnerable population may have positive implications for the dairy industry, as probiotics may encourage improved growth rates and enhanced health in dairy neonates. However, there is variation in existing literature with regard to effectiveness. This study seeks to explore the impact of dietary probiotic supplement on health and growth parameters in pre-weaned dairy calves. Holstein and Jersey calves (n=30) were assigned to 1 of 2 treatment groups, receiving either 0 or 5 grams of probiotic containing …
Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello
Effects Of Probiotic Supplementation On Growth And Health Of Pre-Weaned Dairy Calves, Lily Bello
Honors Scholar Theses
Dairy calf immune development leaves calves susceptible to illness during the pre-weaned stage of life. Previous studies have shown that the use of probiotics during this time may result in increased growth rates and decreased incidence of illness, particularly diarrhea and scours. We hypothesized that by providing probiotics during the time from birth until weaning, calves on study would experience similar growth and health benefits. Neonatal calves (N=32) were provided milk replacer three times daily, with half of the calves receiving Probios® supplements mixed in with their first morning feeding. Growth and health measurements were collected weekly. Probiotic administration significantly …

Colorectal cancer (CRC) is the second leading cause of cancer death in the United States. Modification of the gut microbiome offers potential for CRC prevention.
Evaluation Of Flax Oil Supplementation On Performance Of Growing Dairy Heifer Calves And Lactating Cows, Chelsea Rose Schossow
Evaluation Of Flax Oil Supplementation On Performance Of Growing Dairy Heifer Calves And Lactating Cows, Chelsea Rose Schossow
Electronic Theses and Dissertations
Utilization of flax oil is new to the livestock industry, and limited research has been done to see the benefits of feeding the highly unsaturated oil to both dairy calves and lactating cows. Two studies were conducted to evaluate the potential benefits of flax oil as a lipid supplement. The first study compared the supplementation of two plant based oils to growing dairy calves. Thirty-six female Holstein calves in individual hutches were used in a 12-wk randomized complete block design study. Treatments were: 1) control (CON) with no oil, 2) 80 g/d of flax oil (FLAX), and 3) and 80 …
Influence Of "Added" Whey Protein Isolate On Probiotic Properties Of Yogurt Culture Bacteria And Yogurt Characteristics, Luis Alfonso Vargas Lopez
Influence Of "Added" Whey Protein Isolate On Probiotic Properties Of Yogurt Culture Bacteria And Yogurt Characteristics, Luis Alfonso Vargas Lopez
LSU Master's Theses
Consumers are becoming conscious of their diet, increasing protein intake and avoiding carbohydrates and fats. Whey proteins have branch chain amino acids responsible for muscle building. Whey protein isolate (WPI) contains more than 90% protein. The effect of incremental addition of WPI on probiotic characteristics of pure cultures and cultures in yogurt and yogurt characteristics are not known. The hypothesis was that “added” WPI will influence the characteristics of yogurt culture bacteria in pure form and in yogurt. The objectives were: to determine the influence of added WPI on (1) acid and bile tolerance, growth and protease activity of pure …
Effects Of Probiotics And Yeast Culture On Rumen Development And Growth Of Dairy Calves, Jennifer Marie Laborde
Effects Of Probiotics And Yeast Culture On Rumen Development And Growth Of Dairy Calves, Jennifer Marie Laborde
LSU Master's Theses
Forty-eight calves (heifers n=20, bulls n=28) were randomly assigned one of four dietary treatments which included no additive (C); the yeast culture Saccharomyces cerevisiae (YC); the probiotics Bacillus lichenformis and Bacillus subtilis (P); and both yeast culture and probiotics (YCP). Calves were administered treatments from day 2 to 56 in starter and from day 57 to 84 in grower diets. Body weights were measured at birth and weekly thereafter until day 112 of age. Wither and hip heights were measured weekly. Feed intake, water intake, and fecal scores were recorded twice daily until day 56. Rumen fluid was collected on …
Growth Measurements Of Holstein Females From Birth To Seven Years, H. P. Davis, I. L. Hathaway
Growth Measurements Of Holstein Females From Birth To Seven Years, H. P. Davis, I. L. Hathaway
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
Measurements of growth, to be meaningful, must be taken of various parts of the body, at regular intervals, under standardized environmental conditions, from birth through the growth span of the animal. From these measurements skeletal growth standards may be prepared for the several ages. Such standards can be used to measure growth at any age period. They will serve the research worker as a guide for experimental procedure and will provide the livestock raiser a basis with which his animals may be compared. Present standards of growth for dairy cattle are based mostly upon live weight, although considerable data are …
