Genetic and Genetic-Feeding Regimen Interaction Effects on Lactation, Growth and Carcass Traits in Dairy Cattle
Average daily gan (ADG), usually estimated from initial and final body weights, ignores information provided by intermediate body-weight measurements. Alternative methods to obtain a more precise estimate of ADG were developed and compared using simulation. Estimated generalized least-squares …

Effect of Feeding Different Protein and Energy Supplements on Performance and Health of Beef Calves During the Backgrounding Period
… BW). Supplemented heifers had higher (P<0.05) ADG than unsupplemented heifers by 42 d. Heifers fed the 30% CP supplement had higher (P<0.05) plasma urea-N by d 42. In trial 2 (pasture study 1), 36 steers (average BW = 217 kg) grazed stockpiled tall fescue and were allotted to three treatments: …

Performance and nutrient digestibility in weanling pigs as influenced by yeast culture, whey, and fiber additions to starter diets
… there was no significant overall effect of YC on ADG or G:F in either trial. In Trial 2 of Exp. I, whey depressed overall ADG (P < .10) and G:F (P < .005). In the nursery phases of Exp. I, there were no significant dietary treatment effects on ADG. Gain to feed ratios tended to be increased (P < …

Environmental factors, pasture composition, growth rate and puberty in growing Thoroughbreds
… were compared with day length, IGF-I and ADG using Spearman correlations. Concentrations of progesterone at birth (2.3 ± 0.4 ng/mL) decreased within the first week of life to basal values (0.11 ± 0.01 ng/mL) in colts and fillies. Progesterone in the geldings remained at baseline …

A framework for decision support in systems architecting
… the result of a set of interrelated decisions. ADG's explicit representation of an interconnected decision problem is a bipartite graph of decision variables, property variables, logical constraints, and property functions. The Architecture Decision Graph's framework provide tools for reasoning …

Effect of energy and undegraded intake protein on growth and feed efficiency of growing Holstein heifers
… (30 or SO% CP), energy (supporting .S9 or .91 kg ADG), and source of UIP (blood meal or combination protein supplement). Trial one was a 2x2 factorial, with two levels of energy and UIP. High UIP was achieved with blood meal supplementation. From 6-13 mo of age (phase I), high energy increased ADG …

Quantifying the Effects of Microbial Phytase and Diet Acidity on Ca and P Utilization by Weanling Pigs
… adding phytase to low P diets linearly increased ADG (P < .001), rib shear force (P < .01), shear energy (P < .02), ash weight (P < .001) and ash percent (P < .001), Ca (P < .001) and P (P < .001) digestibility and digestible Ca (P < .001) and P (P <.001). Added P linearly increased ADG (P < …

A Spacetime, Balance-Law Formulation of Coupled Atomistic and Continuum Dynamics for Solids
… element, atomistic discontinuous Galerkin (ADG) method. On the continuum side I develop a two- and three-field SDG formulations for linearized elastodynamics to illuminate the mathematical structure of the original one-field SDG formulation and to assist in making connections to the …

Characterizing meat tenderness of finishing steers fed for different rates of gain
… to characterize effects of average daily gain (ADG) on Warner-Bratzler shear force (WBSF) and characterize effects of ADG on postmortem proteolysis in steers. Thirty-six steers (initial body weight 271 ± 24 kg) were stratified by weight into 6 pens of 6 steers each. Steers were limit fed the …

Effect of circovirus vaccination on immune responses, viral load, and growth performance of pigs under field conditions
… effects of vaccination on average daily gain (ADG), immune responses, and viral circulation under field conditions. In the first study evaluating circovirus vaccination effects on PCV2 antibody titer, regardless of age and dose administration protocol, pigs vaccinated with a 2-dose circovirus …

The effects of feeding aflatoxin contaminated swine diets with clays on performance, mineral metabolism, immune response and liver function in weanling and growing Pigs
… AC. In the nursery phase, average daily gain (ADG), average daily feed intake (ADFI), and feed per gain (F:G) were depressed (P < .05), while serum gammaglutamyltransferase (GGT), alkaline phosphatase levels, and liver weights were increased (P < .05) in pigs fed AC. Feeding SB with AC …

Interactions between skimmed bovine milk and tea infusions under an acidulous environment: a thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… dairy gels produced with tea infusions (ADG), as well as the secondary structure of protein components, were investigated to explore the practicality of using green tea, oolong tea and black tea extracts as an additive in milk products. Reconstituted skim milk was supplemented with …

Effects of Supplemental Fat on Beef Cow and Heifer Performance, Lactation and Reproduction
… fat supplementation increased (P < 0.05) ADG, with the flaxseed resulting in higher (P ≤ 0.05) ADG than the soybeans. Feeding supplemental fat did not affect ( P ≥ 0.05) cow milk production or calf ADG. Supplemental fat increased (P ≤ 0.05) cow milk fat percent and yield with the …

Effects of Ractopamine and Muscle Fiber Number on Swine Growth Performance, Carcass Traits, and Meat Quality
… is attained through shortening days to harvest (ADG), enhancing feed conversion (G:F), and increasing carcass leanness. One method to increase ADG, G:F, and carcass leanness is through the utilization of RAC. Ractopamine hydrochloride is an orally active beta1 adrenergic agonist that is approved …

Intensified Calf Feeding Programs for Purebred and Crossbred Calves
… remained on study for 8 wk. Body weight gain, ADG, total weight gain, and stature measurements were greatest for calves fed 28/25 and lowest for calves fed diet 20/20, whereas calves fed 28/20 were intermediate. In the second experiment, 70 calves were assigned to one of two treatments. Calves …

Forage Utilization and Nitrogen Management of Tall Fescue Stockpiled for Winter Grazing
… how grazing methods impact nutritive value, ADG, and utilization of tall fescue stockpiled for winter grazing. Three treatments (continuous grazing, moved once per week, and moved twice per week) were used. In year one, cattle moved once and twice per week showed significantly higher ADG (P < …
