IGC Proceedings (1977-2023)

An experiment was carried out in spring over 42 days, with 48 multiparous Holstein Friesian cows, to examine the interrelationship of milk yield level, sward height and concentrate level. Two initial milk yield groups of 21.3 and 35.5 kg/day, two range of compressed sward heights of 3 to 5 cm, and 7 to 9 cm , and three concentrate levels of 0 and 6 kg/day and ad libitum were evaluated in a factorial design. Multiple regression analyses were carried out relating intake and behavioural dependent variables to the independent variables initial milk yield (IMY), sward height (SH) and concentrate intake …

Ruminal Fill Effect Of Forages: Prediction And Relationship With Voluntary Intake, R Baumont, A Barlet, J Jamot

IGC Proceedings (1977-2023)

Voluntary dry matter intake (VDMI) and rumen fill were measured on sheep fed with 18 forages ranging from wheat straw to lucerne hay. In vivo fill effect (IVFE i.e. rumen DM pool divided by VDMI), in situ degradability, cell-wall composition, pepsin-cellulase digestibility and in vitro gas production were determined. In situ estimated fill effect (ISFE) was calculated as the retention time of insoluble potential degradable and undegradable fractions using a constant rate of passage. ISFE and IVFE were highly correlated (r2=0.89) but ISFE values were lower than IVFE values because in situ degradability does not integrate comminution time of …

IGC Proceedings (1977-2023)

The objective of this study was to investigate the influence of N fertilization on the quality of Panicum maximum cv. Gatton (Panicum) and the subsequent intake thereof. Hand cut samples increased in N (1.8 - 2.7%) and NO3-N content (0.75 - 1.54%) and decreased in WSC (14.6 - 13.9 g/kg) content, but with no changes in IVDOM as N fertilization levels raised from 0 to 150 kg N/ha respectively. No changes occurred in the NDF and ADL values. The animal selected N, and IVDOM values were higher and NDF value lower than the hand cut samples, which was expected due …

Intake And Partial Digestibility Of Panicum Maximum (Cv. Gatton) At Three Stages Of Maturity During Summer, W.A. Van Niekerk, N F.G. Rethman

IGC Proceedings (1977-2023)

The objective of this study was to determine the influence of stage of maturity on the intake and digestibility of P. maximum (cv. Gatton) during the active growing season. Low DM content at the young and medium growth stages (24.9 and 25.2%) did not hamper DOMI (48.8 and 44.1 g/kg W0.75/d) respectively. The N concentration of the three stages were well within the limit required for optimal rumen microbial production (1.8 - 2.0%). The high NDF value of the adult stage (59.5%) resulted in a significantly lower IVDOM value (62.3%) but the IVDOM values of all stages were on the …

Implications Of Biomechanical Characters Of Subterranean Clover On Feeding By Redlegged Earth Mite And Intake By Sheep, D A. Henry, S K. Baker, T J. Ridsdill-Smith

IGC Proceedings (1977-2023)

The biomechanical strength of cultivars of subterranean clover (Trifolium subterraneum) that were either resistant or susceptible to feeding by redlegged earth mite was measured as the force required to penetrate their leaves with a small, tubular punch. Cotyledons and trifoliate leaves of cultivars resistant to redlegged earth mite had a higher resistance to penetration than cultivars susceptible to redlegged earth mite. Cotyledons needed a higher force to penetrate than trifoliate leaves. The possible implications for intake by ruminants of differences between the cultivars in biomechanical characters are also considered.

Bird Friendly Beef: Exploring The Impacts Of Regenerative Forage Production, B. Rigley, J. Gilley, Aem Johnson

IGC Proceedings (1977-2023)

In the eastern US, managed hayfields and pasturelands represent a significant portion of remaining available grassland bird habitat, hosting several declining species including the eastern meadowlark (Sturnella magna) and the grasshopper sparrow (Ammodramus savannarum). However, these working landscapes have deteriorated in their ability to support grassland birds in recent decades due to more frequent and early hay cuttings and intensive grazing. Since the conservation of grassland birds is inextricably linked to agricultural systems, for conservation to be effective, land management must aim to benefit both producers and birds. Regenerative agriculture is an emerging approach that incorporates …

Percutaneous Endoscopic Gastrostomy: A Possible Trigger For Dieulafoy's Lesion, Ali Tariq Alvi, Elsa Tchouambou, Murali Shankar

HCA Healthcare Journal of Medicine

Introduction

Upper gastrointestinal (GI) bleeding is a medical condition commonly seen in clinical practice due to variable etiologies and a multitude of presentations. The patients can present with hematemesis, melena, or hematochezia in case of severe bleeding. The initial evaluation should involve assessing the hemodynamic status with adequate resuscitation followed by diagnostic tests to identify the source and potentially treat it. Dieulafoy's lesion, sometimes referred to as Dieulafoy's disease, is a rare cause of upper GI bleeding with no clear risk factors, which makes it a diagnostic conundrum. Here we describe an unusual case of Dieulafoy's lesion developing following percutaneous …
