Comparative Ruminal Nitrogen Degradability Of Tropical Browse And Alfalfa Hays, S Toure-Fall, B Michalet-Doreau
IGC Proceedings (1977-2023)
The nitrogen (N) distribution of 2 tropical browse leaves (Balanites aegypliaca and Guiera senegalensis) and of 2 temperate alfalfa (Medicago sativa) hays was determined and the ruminal degradation of total N and fibre N fractions (NDSN, AFN, ADFN) was measured with nylon bag method. The average N degradability of temperate forages was not different, 77.1%, but that of the browse forages varied from 27.5% (G11iera) to 85.1 % (Balanites), The neutraldetergent-soluble N degraded rapidly in the rumen, whereas the aciddetergent-fibre N remained undegraded for all samples. The available fibre N was not high, except …

Trees And Shrubs As Secondary Components Of Pasture, A N. Atta-Krah
Trees And Shrubs As Secondary Components Of Pasture, A N. Atta-Krah
IGC Proceedings (1977-2023)
Traditionally, the concept of pasture has precluded tree crops in any meaningful and productive way. Grasses and herbaceous legumes have been the major components of pasture. The place of trees in pasture is often limited to live fencing, and a few other trees interspersed within the pasture, to provide shade for livestock. In tropical and subtropical areas, where trees are a significant part of the natural vegetation, the non-inclusion· of trees in pasture and agricultural production systems and their increasing rate of disappearance from the zone are giving rise to serious environmental and agricultural concerns. There is an increasing realisation …

IGC Proceedings (1977-2023)
The multi-stata canopy structure of rain forest allows only I% sunlight penetration, too little for the survival of forage beneath it. However, man-made forest plantation (rubber, oil palm and coconut) allows more light for forage species. Initially, 60-70 forage species were recorded under these modified forest canopies but only one third of them survived heavy shading. Forage dry matter yields declined from 2.8-4.8 I/ha DM at immature phase of plantations, to 0.1-1.0 I/Im at mautre phase. Nutrients. available to grazing animals from forages under plantations were guile high (18.4 kg Nit DM and 5609 MJ MEit DM) from native forages, …
Grazing Potential Of Desiccation-Tolerant Tropical And Subtropical Grasses, Y A. Sutaryono, D F. Gaff
Grazing Potential Of Desiccation-Tolerant Tropical And Subtropical Grasses, Y A. Sutaryono, D F. Gaff
IGC Proceedings (1977-2023)
Some desiccation-tolerant grasses possess the potential for use as a grazing source for animals. Some species compared favourably in nutrient content and digestibility with other tropical animal fodder grasses. The Sporobolus species, S. aff, fimbriatus, S. lampranthus, S. pellucidus, together with Eragrostis invalida and Eragrostiella nardoides showed the most promising combination of desirable characteristics. Resurrection grasses contained potentially toxic substances, but, it appears, in amounts harmless to animals, Animal feed trials are needed to test their real feed value, palatability and non-toxicity to animals.

IGC Proceedings (1977-2023)
Behavioural adaptation of Bos taurus (Angus) and B. indicus B: taurus cross (Brangus) females to high ambient temperatures was studied in 2 trials (maximum ambient temperatures of 37 .8 and 32.5°C respectively) in a semi-arid area of south Texas. Brangus females grazed for longer (297 v. 239 min/day, P<0.0001) spent less time in shade (288 v. 395 min/day, P<0.0001), and spent less time watering (95 v. 115 min/day, P<0.0001) than Angus females. Trial by breed interactions were detected (P<0.001) for resting in shade, resting in sun and watering time. Both breeds were apparently restricted in grazing time by high ambient temperatures during both trials, but the Angus were restricted to a greater extent. Although ambient temperatures were lower in the second trial, the threshold for allowing grazing unrestricted by heat stress was apparently not reached for either breed,

Mixed-Species Grazing In The Highland Sourveld Of South Africa: An Evaluation Of Animal Production Potential, M B. Hardy, N M. Tainton
IGC Proceedings (1977-2023)
The effects of mixed-species grazing, at 5 cattle to sheep ratios all at the same stocking rale, on individual animal mass change/ ha mass change/ Ila were monitored for 2 grazing seasons, The ratios were balanced in terms of animal units which equate the expected intake of cattle and sheep. The study was conducted on a humid grasslands in which the herbage characteristically loses quality as Jt mature1. Mass gains of individual cattle were higher when the cattle grazed 10ge1her with the sheep than when they grazed alone. This was ascribed to increasing herbage availability as the ratio of cattle …
Prediction Of Live-Weight Gain Of Cattle Grazing Pastures On Brigalow Soil, M Hirata, C K. Mcdonald, R M. Jones
Prediction Of Live-Weight Gain Of Cattle Grazing Pastures On Brigalow Soil, M Hirata, C K. Mcdonald, R M. Jones
IGC Proceedings (1977-2023)
A model for predicting the live-weight gain-(LWD) of cattle from climatic conditions and pasture and cattle attributes was developed. The model was calibrated and validated against the data from a long-term grazing experiment on brigalow soil, sown with green panic pastures. When validated, the model tended to overestimate LWG as the proportion of green panic (Panicum maximum var. trichoglume) in the pasture decreased, because the model was calibrated, without considering species composition, to data from years when green panic was dominant. This study emphasises the limitations of empirical models of grazing systems. The study also implies that there …

Beef Production From Commercial Leucaena Leucocephala Pastures In A Dry Subtropical Environment, R L. Clem, C R. Esdale, M J. Conway, D Macintyre
IGC Proceedings (1977-2023)
Leucaena leucocephala is a legume widely adapted to the tropics and subtropics and is currently recommended for sowing on fertile clay soils in the subconstal (100-1000 mm) rainfall areas of Queensland. It produces high quality forage that can be used as browse with native or sown grass pastures to improve live-weight gain of grazing beef cattle. At Banana in central Queensland a commercial grazing enterprise has been developed on 1450 ha of land cleared of brigalow scrub and cropped for 20-30 years before sowing to leucaena. Leucaena has been established on about 80% of the property. Stocking rates are varied …

Improving Livestock Production Using The Heavy-Duty Blade Plough On Pastures Infested With Brigalow Suckers, P Filet, J Agnew, R Barnett, J Clewett
IGC Proceedings (1977-2023)
Reducing brigalow {Acacia harpophylla) sucker numbers is necessary to maintain the productivity of grass pastures on brigalow soils in' Australia. Blade ploughing brigalow sucker regrowth is an effective control oplion. A 97% mortality was achieved when brigalow suckers were treated with a blade plough in central Queensland. Pasture yield was 3 times higher in a blade-ploughed paddock than in an adjacent sucker paddock 6 months after treatment and after 2 more summers. During 3 years of grazing, stocking rates were 7 .5 ha/steer in the sucker paddock and 2.3-3.2 ha/steer in the blade0ploughed paddock, Annual· live-weight gains/head were …

Animal Feed Research In Eastern And Southern Africa: Historical And Actual Priorities, Samuel C. Jutzi, J C. Tothhill
IGC Proceedings (1977-2023)
A review of animal feed research reports from 7 countries of eastern and southern Africa is used to assess historical and actual research emphases. Priority was on feed supply and evaluation for cattle production with strong rangelands improvement programmes. Most research focused on ecologically favoured regions and larger-scale livestock commodity production. Strong efforts for the exploitation of grasses for improved feed supply were supported by legume work for feed quality improvement. There was a strong emphasis on feed agronomy work, one third of all that work involving animals. Component research results were reported with little discussion of target systems implications, …

Tropical Pasture Establishment In Thailand By Direct-Drilling, C Lekchom, S Sukpituksakul, N Wongsuwan, B R. Watkin
IGC Proceedings (1977-2023)
The establishment, early production and quality of 4 tropical grasses was compared when established by direct-drilling into uncultivated, herbicide-kllled pasture or when sown into a fully cultivated, wellprepared seedbed. Direct-drilling resulted in significantly better establishment and early production than drilling into a prepared seedbed at the first cut, but not at subsequent cuts. Forage quality in terms of both crude protein and dry matter digestibility was high in all treatments, with no difference between sowing techniques and only small differences between species. Results are discussed in relation to farming practice.

Cultivated Pasture, Forage On Offer And Animal Responseg, G E. Maraschin, A De Moraes, L.F. A. Da Silva, J Riboldi
IGC Proceedings (1977-2023)
Animal gains on pasture are influenced by the forage dry mailer on offer (DMO). To ascertain this relationship a pangola grass (Digitaria eriantha) pasture was evaluated under forage DMO levels of 3.5%, 7.0%, 10.5% and 14.0% of live weight (LW)/head/day. Two steers were assigned to each treatment as tester animals plus a number of put-andtake steers to maintain the desired levels of forage DMO, at the Estacao Experimental Agronomica • UFRGS • 30°S, from November 1989 to March 1990 (period I) and from October 1990 to May 1991 (period II).

Effect Of Supplementation On Pasture Selection By Grazing Steers. I. Quality Of Ingested Forage, O R. Rosso, P O. Gomez, F Overjero
IGC Proceedings (1977-2023)
Three oesophageal fistulated Hereford steers (average live weight 304 kg) were supplemented throughout a trial at 0, 0.7 or 1.4% of live weight, with a mixture of 90% ground maize and 10% sunflower expeller. Adaptation and sampling periods were 7 and 4 days respectively. Steers were allocated randomly to 4 Agropyron•dominated pastures of 1800, 2000, 8200 and 8900 kg OM/ha and leaf percentage of 5.8, 28.9, 23.2 and 14.0, respectively. Fistula samples were taken once daily, air dried at 60°C and analysed. Supplementation significantly (P<0.05) affected DM digestibility, which was 51.3, 54.7 and 57.2 for 0, 0.7 and 1.4% levels, respectively. Nitrogen and cell wall content differences were not detected. It appears that supplemented steers preferred pasture components with the highest digestibility.

Seasonal Changes In The Dry Matter Digestibility Of Individual Tillers Of Napiergrass At Two Sites Of At Different Altitudes, Y Ishii, K Ito, H Numaguchi
IGC Proceedings (1977-2023)
An investigation was made into the seasonal changes in the in vitro dry matter digestibility (IVDMD) of leaf blade (LB) and stem (ST) of individual tillers of napiergrass (Pennisetum purpuretum) grown at the high-altitude site (HA) and low-altitude site (LA) in Miyazaki prefecture, south-western Japan. Within a single sampling date, the variation in the IVDMD with tillers was small both for LB and ST. Negative logarithmic relationships held between the LB percentage and tiller dry weight and between the IVDMD and dry weight of LB and ST. The HA plants produced less dry matter as well as digestible …

Tropical Pastures For Dairy Heifers In The South-Eastern Region Of Brazil, S Aronovich, S R. De Carvalho, Mm Aronovich
IGC Proceedings (1977-2023)
A number of experiments using improved tropical pastures (mostly Digltaria decumbems cv. Transvala) for heifers were made in the south-eastern region of Brazil from 1970. The results are presented as: (A) experiments with heifers during· the nursing period, (B) experiments with heifers after. weaning and (C) experiments with heifers older than 6 months. The results and the economical analyses lead to the following conclusions: ( 1) the use of well managed, improved tropical pastures enables adequate growth and development of dairy heifers, (2) the heifers reach sexual maturity before 20 months of age, and (3) the cost of replacement heifers …
Mineral Supplementation And Phosphorus Fertilizer Application On Native Pastures In North-East Argentina, R M. Pizzio, O Royo Pallares
Mineral Supplementation And Phosphorus Fertilizer Application On Native Pastures In North-East Argentina, R M. Pizzio, O Royo Pallares
IGC Proceedings (1977-2023)
Extensive cattle production systems in north-east Argentina are based on the use of native pastures. One of the most important limiting factors to improve production is the acute phosphorus deficiency of soils and pastures. A large experiment was set up to study the effect of phosphorus fertiliser and mineral supplementation on the liveweight gain of steers of 2 ages grazing native pastures. Supplementation with a mixture of bone meal and salt, residual effect of P fertilisation, and both treatments applied together increased the annual animal live-weight gain by 60, 66 and 106%, respectively. The response of younger steers to fertiliser …

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works
Dendritic mesoporous silica nanoparticles (DMSNs), characterized by a high specific surface area and abundant hydroxyl groups, offer a promising approach to enhancing the performance of amphiphilic polymers in challenging enhanced oil recovery (EOR) conditions. In this study, DMSNs were successfully synthesized, and systematically evaluated for their impact on the solution properties of a betaine amphiphilic polymer (PADC). The unique "flower-like" mesoporous structure of DMSNs provided approximately 7-fold higher surface area than conventional SiO2, facilitating enhanced polymer-nanoparticle interactions. The DMSN/PADC composite system exhibited significantly improved viscosity, salt resistance, thermal tolerance, and shear resistance compared to PADC and SiO2/PADC systems. Quantum chemical …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
The Tibetan Plateau, known as the “Asian water tower,” is a hotspot for complex hydroclimatic changes. We reveal that the previously decreasing atmospheric evaporative demand (Eo) trend at the end of the 20th century has reversed over the last two decades. Although both wind stilling and solar dimming have persisted, their effects on Eo rates have been overshadowed by increasing air temperatures and decreasing relative humidity, leading to a net rise in Eo for 1980−2015. Using the empirical “top-down” Budyko approach, we estimate that across seven sub-catchments draining the Tibetan Plateau, a 10% increase in annual-averaged …

Geochronological And Isotopic Data From The Adakitic Dodurga Pluton (Central Pontides, N Türkiye): New Insights For The Geodynamic Evolution Of The Northern Neotethys, Okay Çi̇men, Mehmet Ali̇ Gücer, Antonio Simonetti, Fati̇h Karaoğlan
Turkish Journal of Earth Sciences
The Dodurga Pluton is located within the Central Pontides (northern Türkiye) and, has a SW-NE elongation, and consists of granodiorite and dacite porphyry. Previous studies have suggested that this pluton is Triassic in age, and its whole-rock geochemical systematics are consistent with those from adakitic magmatic occurrences rather than the classic arc granitoid suite. This study reports the first time in-situ/whole-rock radiogenic isotopic (Sr, Nd and Pb) and mica/amphibole Ar-Ar age data to evaluate better its petrogenetic-geodynamic evolution and chemical nature of mantle source(s). Unlike previous data, combined new in-situ zircon U-Pb yield Late Cretaceous crystallization ages of 84.2±0.9 Ma …

The conservation of freshwater turtle species depends on precise and effective monitoring techniques. Environmental DNA (eDNA) analysis is a potential method for identifying cryptic and elusive turtle species in aquatic ecosystems. eDNA analysis can help to identify key regions for conservation efforts and monitor changes in population levels over time. This study aims to evaluate the effectiveness of a rapid eDNA detection method for the yellow mud turtle (Kinosternon flavescens, an indicator species that is endangered in some states in the USA), which inhabits local oxbow lakes (e.g., resacas) in Cameron County, South Texas. A species-specific nested PCR …

As the spatiotemporal overlap between burned forests, seasonal snow, extreme precipitation, and mid-winter warming continues to increase with climate change, it is critical we quantify the impacts of forest fires and rain-on-snow (ROS) on mid-winter snowmelt and snow-water resources. In the Pacific Northwest, the release of large volumes of meltwater to downstream receiving water from already vulnerable snowpacks can have catastrophic consequences. I show that forest fires doubled mid-winter snowmelt proportions as compared to unburned reference sites, using a novel network of snow monitoring and micrometeorological stations installed across an elevational and forest type gradient in a burned watershed in …
