Effect Of Variation In The Quality Of Forage Maize Silage In Ireland On Forage Intake And On Milk Production Of Dairy Cows, J J. Fitzgeald

IGC Proceedings (1977-2023)

In three experiments maize silages which varied in quality, i.e. starch content and dry matter digestibility (DMD) replaced a high proportion (60-67%) of grass silage in the diet of cows in early or mid-lactation. In each experiment the forages were supplemented with concentrates (4 or 6 kg/cow/day). Replacing high quality grass silages (DMD 750 g/kg) with high quality maize silages (starch 219 or 355 g/kg DM, DMD 694 or 754 g/kg) significantly increased forage intake, milk yield, milk protein concentration and the yield of fat and protein (Experiments 1 and 3). Replacing grass silage with a low starch maize silage …

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 …

Foliar Supplementation Of Minerals To Prevent Calcium And Magnesium Deficiencies In Dairy Cows, G F. Wilson, W J. Courtney

IGC Proceedings (1977-2023)

The objectives of this study were to examine the possibility of reducing the incidence of calcium and magnesium deficiencies in cows by feeding anionic salts and by manipulating the mineral concentrations in pastures with foliar sprays during late pregnancy. Cows provided with a mineral supplement of magnesium chloride and ammonium sulphate before calving produced more milk solids and experienced less health problems. The foliar application of anionic salts, with and without sodium chloride, altered the cation balance in pastures grown on 6 different soils.

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 …

Influence Of Different Cutting Frequencies And Fertilization On Grass Silage Quality, U Wyss, R Vogel

IGC Proceedings (1977-2023)

The influence of different cutting frequencies and fertilization on dry matter yield, botanical composition, nutrient concentration and fermentation quality of grass silage was investigated. Altogether four treatments were compared; two 5-cut-treatnents with two different fertilizer levels, one 3-cut-treatment with fertilizer and one 2-cuttreatment without fertilizer. In the 5-cut-treatments the double fertilizer amount produced a 10% higher dry matter yield and also a higher proportion of grasses. The fermentation quality of these silages was mostly good, especially in autumn when the high nitrate content improved the quality. The 3- cut and 2-cut-variants showed a higher grass proportion, a higher crude fibre …

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.

Breeding To Improve Yield And Quality In Napiergrass, Y K. Cheng, C S. Chen

IGC Proceedings (1977-2023)

The breeding program has been conducted to improve the production and quality of napiergrass by crossing with related species or intraspecies. CV. TLG2 with high yields and water soluble carbohydrates have been selected and released. It produced 20% more forage yields and water soluble carbohydrates than cultivar, CV. A146 and persisted well at least for five years. Good silage was obtained when the CV. TLG2 was harvested at the right time. Milking ability is improved by use of silage and/or green chopping whole year round.

Use Of Nir To Estimate Nitrogen Degradability Of Forage, R Agneeseens, P Dardenne, Ph Lecomte

IGC Proceedings (1977-2023)

Near infra red spectrometry (NIRS) is commonly used to characterise animal feeds at the level of their intrinsic composition (dry matter, protein, fat, fiber) as well of their digestibility (Dardenne et al.,1991). The use of new systems in the evaluation of the protein value has induced the necessity to determine parameters such as the theoretical ruminal degradability of nitrogen (DT).

The definition of this criterion necessitates the implementation of the nylon bag technique which is time consuming and costly and is reserved to reference laboratories. An alternative to this technique, based on an enzymatic hydrolysis of the proteinic content, has …

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 …

Rowan-Virtua School of Translational Biomedical Engineering & Sciences Departmental Research

Staphylococcus aureus (S. aureus) is an opportunistic pathogen that lives on surfaces and skin and can cause serious infections inside the body. Antimicrobial peptides (AMPs) are part of the innate immune system and can eliminate pathogens, including bacteria and viruses, and are a promising alternative to antibiotics. Although studies have reported that AMP-functionalized hydrogels can prevent bacterial adhesion and biofilm formation, AMP dosing and the combined effects of multiple AMPs are not well understood. Here, three AMPs with different antibacterial properties were synthesized and the soluble minimum inhibitory concentrations (MICs) of each AMP against methicillin-susceptible S. aureus (MSSA) and methicillin-resistant …

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 …

Nonlinear Biopsychosocial Resilience: Self-Organization As The Basis For A Common Framework, Adam W. Kiefer, David Pincus

Psychology Faculty Books and Book Chapters

Recently, calls have been made for a common framework to understand human resilience through the lens of dynamical systems theory. This chapter provides a comprehensive introduction to the concepts and tools necessary for such an approach. It builds on an existing theoretical framework of biopsychosocial resilience grounded in self-organization theory. This theoretical framework is applied to the formalization of four types of resilience – robustness, resilience, antifragility and grit. Next, important features of stability, structural integrity, and flexibility are discussed as empirically measurable characteristics of a systems-based approach to resilience, which provide a foundation for further applications, including metastability and, …

The dynamics of cyclopentadiene (CP) following optical excitation at 243 nm was investigated by time-resolved pump-probe X-ray scattering using 16.2 keV X-rays at the Linac Coherent Light Source (LCLS). We present the first ultrafast structural evidence that the reaction leads directly to the formation of bicyclo[2.1.0]pentene (BP), a strained molecule with three- and four-membered rings. The bicyclic compound decays via a thermal backreaction to the vibrationally hot CP with a time constant of 21 ± 3 ps. A minor channel leads to ring-opened structures on a subpicosecond time scale.
