Evaluation Of Feeding Alternative Feedstuffs Including Hydroponic Barley Sprouts And Carinata Meal To Dairy Cattle, Rhea D. Lawrence
Evaluation Of Feeding Alternative Feedstuffs Including Hydroponic Barley Sprouts And Carinata Meal To Dairy Cattle, Rhea D. Lawrence
Electronic Theses and Dissertations
The purpose of this dissertation research was to examine alternative feed ingredients not typically found in dairy cattle diets. In total, four studies were conducted to evaluate feedstuffs such as hydroponic barley sprouts and carinata meal and how they affect cattle performance. To determine how feeding hydroponic barley sprouts would affect growing dairy heifer and lactating cow performance two feeding studies were conducted. In the first study, inclusion of 14 % (DM basis) hydroponic barley sprouts (HYD) was evaluated in an ad libitum total mixed ration (TMR) compared to a control (CON) diet on dairy heifer performance during a 12 …
Response Of Dairy Cows To Dietary Starch Concentrations: Performance, Nutrient Digestion, And Gas Emissions, Juan Isidro Sanchez-Duarte
Response Of Dairy Cows To Dietary Starch Concentrations: Performance, Nutrient Digestion, And Gas Emissions, Juan Isidro Sanchez-Duarte
Electronic Theses and Dissertations
Three studies and a meta-analysis were conducted to determine the performance, nutrient digestion, and gas emissions of dairy cows fed diets with different starch concentrations (19 to 27% of DM). Study 1 evaluated the effects of reducing corn grain starch with non-forage fiber sources (NFFS, soybean hulls and beet pulp) in diets of soybean meal (SBM) or canola meal (CM). In study 1, reducing starch from 27 to 20% with soybean hulls and beet pulp had a negative effect on dry matter intake (DMI), milk yield and energy-corrected milk (ECM), regardless of the crude protein (CP) source. Those effects were …
