Herbage Quality At Continuous Grazing With Dairy Cows At Different N-Intakes And Sward Types, K Soegaard, O Aaes

IGC Proceedings (1977-2023)

Herbage quality was examined in paddocks continuously grazed by dairy cows fed supplements with low and high N. There were two sward types for each level of supplement, i.e. fertilized perennial ryegrass (Lolium perenne L) and unfertilized perennial ryegrass/white clover (Trifolium repens L) with a mean clover content of 49 % of dry matter. Decreasing N-intake from 307 to 140 g N cow -1 d -1 by feeding low-N supplements had a small influence on herbage quality in spite of the reduced N-output via urine and faeces. Variation in herbage quality was large during the growing season. The fibre concentration …

Characterizing Effective Fiber With Particle Size And Fiber Concentration Interactions, D R. Buckmaster, A J. Heinrichs, R A. Ward, B P. Lammers

IGC Proceedings (1977-2023)

Both physical form and chemical nature of fiber is important to ruminant animals. A recently developed method for determining particle size distribution was used to characterize typical distributions for forages and total mixed rations (TMR) from the Mid-Atlantic region of the U.S. An effective fiber index (EFI) and modified effective fiber index (MEFI) are proposed which link physical and chemical characteristics. The EFI and MEFI are computed by weighting NDF concentrations by particle size distribution and effectiveness for contribution towards a rumen mat and rumination.

Quality And Nutritive Value Of Alfalfa And Grass Silages With Biological Additives, H Shorko-Sajko, W Bednarski, J Kowalewska-Piontas, J Sajko, K Mlynarczyk

IGC Proceedings (1977-2023)

The present study satisfactorily utilized some food industry byproducts for improving fermentation characteristics, quality and nutritive value of silages. Five kinds of preparations were made: sugar-enzymes based (beet molasses and brewer’s yeast, mycelium of Aspergillus niger, malted barley at 3:3:3:1); enzymes-bacteria based (mycelium of Aspergillus niger, malted barley, acidic whey, fermentation broth and lactic acid bacteria or skim milk powder at 3:0.9:3:0.1); sugar based (molasses and brewer’s yeast at 1:1) and concentrate of lactic acid bacteria only. Untreated or additive-treated first-cut low sugar (60g kg-1DM, 19.4% DM) alfalfa ( Medicago sativa) plus grasses (Phleum pratense and Dactylis glomerata) was …

A Dynamic Model For Changes In Nutritional Value In Grass. An Approach To Modify The Model To A Mixed Ley With Grass And Red Clover, A.-M Gustavsson

IGC Proceedings (1977-2023)

The objective of this approach was to check the possibility to modify a dynamic model for simultaneous simulation of the above-ground dry matter growth (DM) and concentrations of crude protein CP) and metabolizable energy (ME) in stands of timothy (Phleum pratense L.) to a model for mixed leys with timothy and red clover (Trifolium pratense L.). DM growth is estimated in relation to intercepted radiation, air temperature, soil-water status and tissue-N concentration. CP is estimated in relation to plant uptake of N from soil mineralization, nitrogen fixation and applied fertilizer, and dilution of N during plant growth. ME …

Effect Of Calcium Nutrition On The Formation Of Calcium Oxalate In Kikuyu Grass, J P. Marais, A D. Barnabas, D L. Figenschou

IGC Proceedings (1977-2023)

The objective of this investigation was to study the formation of calcium oxalate crystals in situ in kikuyu grass (Pennisetum clandestinum) and to determine the effect of calcium uptake on the soluble and insoluble oxalate content of the grass. Oxalate crystals were more abundant in high-calcium leaves than in low-calcium leaves. Electron microscopy showed that the oxalate crystals are formed in association with globular electron-dense bodies in the vacuole of certain cells. The calcium content of kikuyu is increased by increasing the calcium level of the growth medium. However, the increased amount of calcium taken up by the …

Selection For High Dry Matter And Nonstructural Carbohydrate Contents In Italian Ryegrass, J P. Marais, M De Figueiredo, D.C W. Goodenough

IGC Proceedings (1977-2023)

The objective of this investigation was to determine whether or not the selection parameters, dry matter and total nonstructural carbohydrate contents, in an Italian ryegrass (Lolium multiflorum) selection trial were linked to other traits affecting nutritive quality. Selected F3 plants had significantly higher dry matter and total nonstructural carbohydrate contents than the commercial control plants tested. Although differences in digestibility in vitro of selected plants and control cultivars were non-significant, the selected plants contained less acid detergent fibre and acid detergent lignin than the controls. Acid detergent fibre and acid detergent lignin, the main anti-quality factors associated with pasture …

Forage Quality Of Klein And Angleton Grasses As Standing Hay In The Dry Tropic, J A. Ortega-S, R Guarneros, J M. Avila, M A. Hussey

IGC Proceedings (1977-2023)

This study was conducted at Aldama Experimental Station of INIFAP, in Aldama, Tamps., Mexico, to determine the quality and nutritive value of angleton (Dichanthium aristatum Poir.) (A) and klein (Panicum coloratum L.) (K) pastures used as standing hay. Pastures were closed to grazing in September to promote herbage accumulation until February when the experiment was initiated. Two 200 kg live weight crossbred steers were set stocked per each replication. Two fistulated steers were used to collect extrusa samples every 16 days during the 83-d experimental period. Average daily gain in K was 1.3 times higher (P<0.01) than in A. Crude protein concentration was similar (P > 0.01) in leaves of …

Rumen Fermentation Kinetics Of Grass Measured In Sacco And With The Gas Production Technique, J W. Cone, H Valk

IGC Proceedings (1977-2023)

Rumen fermentation kinetics of grass and silage, differing in age and yield (1500 -7900 kg DM ha-1), were studied in sacco and in vitro, using the gas production test and the Tilley and Terry technique. An increasing yield increased the content of NDF and lignin in grass and decreased protein content, in vitro degradability measured by the Tilley and Terry method, and rate of fermentation measured with the gas production technique and the nylon bag method. The same ranking in fermentation characteristics was observed using the gas production test, the nylon bag method and the Tilley and Terry method. The …

Agronomic And Silage Quality Traits Of Winter Cereals, M K. Siefers, K K. Bolsen

IGC Proceedings (1977-2023)

Agronomic and silage quality traits were examined for 12 winter cereals harvested at two stages of maturity. Forage dry matter (DM) yields were higher at the mid-dough than the early-heading stage. Post 90 barley (Hordeum L.) had the highest whole-plant DM yield at the early-heading stage, and Presto triticale (X Triticosecale Wittmack) had the highest yield at the mid-dough stage. Newton wheat (Triticum aestivum L.) had the lowest whole-plant DM yield at both stages of maturity. Both crude protein (CP) and ash contents were higher for the early-heading than the mid-dough cereals. All 24 silages were of relatively …

The Energetic Utilization Of Forages In Fresh And Dried Condition By Ruminants, W Jentsch

IGC Proceedings (1977-2023)

The influence of dehydration of forages on digestibility and energy utilization was measured by indirect calorimetry in respiration chambers with adult wether sheep as a model for ruminants. Comparisons were carried out between fresh and carefully dried forages (experiment 1) and between fresh and not only carefully but also severely dried forages (experiment 2). Careful drying caused no change, but severe drying decreased energy and especially crude protein digestibility. There were no differences in utilization of metabolizable energy between fresh and carefully or severely dried forages.

Minerals In Forages Of Southern Italy Relate To Climate And Harvest Time Effects, G Convertini, D Ferri

IGC Proceedings (1977-2023)

Three cultivars of Alfalfa (Ascolana, Bresaola L 202 and Canè) in the Apulian “Tavoliere” (southern Italy) environment were studied. The effects of three water levels (watering of 1000 m3 ha-1 after each cut; 500 m3 ha-1 as above and another water supply with the same volume when the plant reached wilting conditions; with watering of 300 m3 ha-1 every 8 days to assure continuous water availability) and two cutting times (flower bud and 50% of flowering) were investigated. The cultivars showed a different mineral composition only for quantities not for qualities. The mineral composition of three cultivars were similarly influenced …

Genetic Variation In Perennial Ryegrass For Volatile Fatty Acid Production In Rumen Fluid, H.J P. Marvin, E N. Van Loo, O Dolstra, C.H A. Snijders, D Reheul, J W. Cone

IGC Proceedings (1977-2023)

In perennial ryegrass genetic variation was shown not only for in vitro organic matter degradation (OMD) in rumen fluid and neutral detergent fibre content (NDF) but also for production of volatile fatty acids (VFAs) upon in vitro incubation in rumen fluid. The correlations among concentrations of VFAs in the incubation fluid were high. OMD and NDF, on the other hand, were poorly correlated to the VFA concentrations.

Characterization Of Legume And Grass Residues Following In Vitro And In Sacco Ruminal Digestion, D.J R. Cherney, J H. Cherney, A H. Davidson

IGC Proceedings (1977-2023)

Objectives were to characterize the influence of forage species and maturity on dry matter degradation. Averaged across maturities, alfalfa and red clover were lower in NDF content (39 and 30% NDF, respectively) than reed canarygrass and timothy (59 and 54% NDF, respectively). The NDF of the DM residues in grass remained relatively unchanged over time, while NDF of the DM residue in legume increased rapidly for 9 h before becoming relatively constant. Alfalfa incubated in vitro (42% NDF) compared to reed canarygrass (58% NDF) contained more ND soluble material (39% vs. 25%), and more pepsin soluble material (22 vs. 18%). …

Potassium Accumulation In Perennial Cool-Season Grass Forage, J H. Cherney, D.J R. Cherney

IGC Proceedings (1977-2023)

Perennial grasses are well adapted to the northern U.S.A. and Canada, but the potassium (K) content of grass forage is a major concern in regard to dairy cattle nutrition. Our goal was to identify factors influencing potassium content of grasses, so that a grass management strategy for controlling potassium content could be formulated. Separate experiments were conducted with several perennial coolseason grass species and varieties. Nitrogen fertilization and harvest management also were evaluated. Aside from the obvious positive effect on K concentration caused by commercial K fertilizer or by animal manure application, K concentration was influenced by grass species, grass …

Seasonal Changes In Forage Quality Of C3 Grasses On Sagebrush Grassland, H F. Mayland, G E. Shewmaker

IGC Proceedings (1977-2023)

Annual and perennial grasses growing in the semiarid, west-central North American continent mature by early to midsummer. Forage mineral concentrations in these C-3 grasses decrease curvilinearly as the season advances from day of year (DOY) 75 to 300. Total digestible dry matter (TDDM) and digestible cell wall (DCW) decrease linearly with DOY while neutral detergent fiber (NDF) increases curvilinearly. By midsummer; energy, N, P, and Zn usually become deficient for ruminant nutrition.

Protein Degradability Effect And Supplementation Level On Pasture Utilization, A.V M. Franco, P De Andrade, G L. Franco

IGC Proceedings (1977-2023)

The objective was to determine the effect of protein degradability and supplement level on forage degradation. Steers fistulated were utilizated in brachiaria (Brachiaria brizantha) pasture. A randomized block design was used with a control treatment and supplements according to a factorial scheme combining low, medium and high protein degradability with supplementation levels: low, medium and high analysed as principal treatments and incubation time as splitplot by SAS. Nylon bags were incubated at 4; 8; 12; 24; 48; 72; 96 and 120 hours to determine DM, CP and NDF degradation. There was no effect (P>0.05) of protein degradability …

Energetic Feed Value Of Grassland Products In Ruminants, A Chudy

IGC Proceedings (1977-2023)

A method for calculating the energetic feed value, based on the digestible nutrients and on the relations of the utilisation of the energy of the nutrients (carbohydrates = 100) for ATP syntheses is described. This relative scale is a nominal feed value (NFV). It characterises the ATP potential of the feedstuffs and is therefore equivalent to the efficiency of utilisation of the feed energy in the catabolic metabolism (non-thermal maintenance, muscular work (movement)) and energy costs for syntheses as well as the productive performance as energy retention in animal products. Therefore this scale secures a precise precognition of the animal …

Baltic Journal of Health and Physical Activity

Introduction: Observing parents’ body-focused behaviours during middle childhood is one of the initial ways in which children model their perceptions of pro-health attitudes and their connection to physical attractiveness. This study aimed to investigate the relationship between parents' health behaviours, their appearance, and the perceptions of adult body types (skinny, medium, obese) by their five-year-old children. Moreover, the role of gender in the above relationship for both children and parents was also examined. Materials and methods: This study participants were 680 families with five-year-old children (330 girls). Participation was limited to the moth-er-father-child triad. The Beauty and Health Scale, Healthy …

Working With Bilingual Populations: Clinical Practices Of Speech-Language Pathologists In New Mexico, Wylie L. Skillman

Speech and Hearing Sciences ETDs

New Mexico is uniquely positioned as a state that has more bilingual speakers than the United States on average, meaning that Speech Language Pathologists (SLPs) here are more likely to work with bilingual speakers than elsewhere. Best practices for bilingual evaluation and treatment are taught in graduate education for SLPs but the extent to which they are known and utilized by school-based SLPs differs based on many factors.

As the body of research supporting culturally responsive bilingual assessment and intervention continue to grow, it is unknown how or if clinicians are using this knowledge to assess and treat students who …

Integrity, Flexibility, And Balance: How Change Works In Psychotherapy, David Pincus

Psychology Faculty Books and Book Chapters

Psychotherapy may be the most tested form of health intervention and also one of the most mysterious. Clinical trials, and meta-analyses of these trials, have repeatedly demonstrated the effectiveness of psychotherapy, while also failing to uncover any clear-cut and consistent understanding of how psychotherapy works. This lack of understanding has driven the field to develop 500 supposedly distinct, yet equivalently effective “theories.” The field suffers from barriers to scientific discovery, barriers to therapist training, and barriers to people seeking help for their psychosocial problems. This chapter tackles the mystery of how therapy works by examining the shortcomings of modern medical …

Changes In Lean Body Mass With Glucagon-Like Peptide-1-Based Therapies And Mitigation Strategies, Ian J. Neeland

Faculty Scholarship

Weight loss induced by glucagon-like peptide-1 receptor agonists (GLP-1RAs) and dual glucagon-like peptide-1 receptor (GLP-1R)/glucose-dependent insulinotropic polypeptide receptor agonists is coming closer to the magnitudes achieved with surgery. However, with greater weight loss there is concern about potential side effects on muscle quantity (mass), health and function. There is heterogeneity in the reported effects of GLP-1-based therapies on lean mass changes in clinical trials: in some studies, reductions in lean mass range between 40% and 60% as a proportion of total weight lost, while other studies show lean mass reductions of approximately 15% or less of total weight lost. There …

Legalized Sports Betting And Mental Health, Brad R. Humphreys, Jane Ruseski

Economics Faculty Working Papers Series

Since the Supreme Court declared the Professional and Amateur Sports Protection Act of 1992 unconstitutional in 2018, 38 states and the District of Columbia legalized face to face and/or on-line betting on sports. A potential unintended consequence of legalized sports betting is an increased risk for mental health disorders and problem gambling. Using a staggered difference-in differences framework, we exploit variation in timing of adoption of legal sports betting across states to evaluate the impact of these laws on mental health outcomes. We combine data on when states passed laws to legalize gambling with data from the Behavioral Risk Factor …

Dietary Saturated Fatty Acids Modulate Host Innate Immunity, Amy Lorraine Seufert
