Effects Of Small Intestinal Starch Digestion And Dietary Lipid On Efficiency Of Nitrogen Use In Cattle, Ethan J. Blom
Effects Of Small Intestinal Starch Digestion And Dietary Lipid On Efficiency Of Nitrogen Use In Cattle, Ethan J. Blom
Electronic Theses and Dissertations
The objective of this research was to determine the effects of increases in energy available for gain from increased small intestinal starch digestion (SISD) and dietary lipid source and amount on the efficiency of N use in cattle. Five ruminally, duodenally, and ileally cannulated steers were placed in a 5 × 5 Latin square. Each received duodenal infusion of 1.5 ± 0.08 kg/d raw cornstarch and either 0, 30.9 ± 0.59, 62.4 ± 1.16, or 120.4 ± 3.39 g/d Glu, or 387.9 ± 17.47 g/d casein. Casein increased (P = 0.05) SISD. Similarly, greater duodenal Glu linearly (P = 0.02) …
Analysis Of Starch Branching Enzyme 1 (Sbe1) Gene In Maize, Abiskar Gyawali
Analysis Of Starch Branching Enzyme 1 (Sbe1) Gene In Maize, Abiskar Gyawali
Electronic Theses and Dissertations
A previous study revealed a quantitative trait locus (QTL) in maize on the short arm of chromosome 5 (5S) for endosperm amylose content. In that original study, both low and high amylose parental lines, H99ae and GEMS-0067 respectively, were homozygous recessive for amylose extender 1 (ae1) and the polymorphism responsible for this QTL was additive (semi-dominant). Located within the QTL interval is starch branching enzyme 1 (sbe1), which makes it a candidate gene. In order to test whether a polymorphism in sbe1 is the source of this QTL, we crossed a plant homozygous for ae1 and sbe1-Mu onto a …
Study Of The Effect Of Feeding Highly Digestible Corn Based Calf Starter On The Growth Performance Of Calves, Shruti Srivastava
Study Of The Effect Of Feeding Highly Digestible Corn Based Calf Starter On The Growth Performance Of Calves, Shruti Srivastava
Electronic Theses and Dissertations
New corn hybrids have been developed by Masters Choice (MC) that vary in energy density and starch digestibility. These MC hybrids have lower starch densities due to an altered starch structure, which allows for greater ruminal and intestinal starch digestion. The altered starch structure of these new hybrids results in reduced feed manufacturing costs (i.e., grinding). Thirty (30) 1 to 3 d old (40.6 ± 1.72 kg) Holstein heifer calves were randomly assigned to 1 of 2 calf starters to measure growth performance of Holstein heifer calves through 8 weeks of age. Treatments were: 1) Hard starch (HS) corn calf …
