Mineral Status Of Some Permanent Range Plants For Grazing Sheep In Semi-Arid Areas Of The Chaharmahal And Bakhtiari Province In Iran. 1. Some Macro Minerals, G. H. R. Shadnoush

IGC Proceedings (1997-2023)

A deficiency of one or more of the essential minerals in animals can lead not only to a decrease in productivity but also to metabolic diseases in case of severe deficiencies (McDowell, 1985). In general, mineral, especially phosphorous, deficiencies and imbalances are reported from almost all tropical regions of the world (Matijovic & Durackova, 1994). This study was designed to measure the calcium, phosphorous, magnesium, potassium, sodium and chlorine contents of some plant species in the semi-arid rangeland of Chaharmahal & Bakhtiari Province in Iran, because little information is available at present.

The Effect Of Two Magnesium Fertilisers, Kieserite And Mgo, On Herbage Mg Content, M. B. O'Connor, A. H. C. Roberts, R. Haerdter

IGC Proceedings (1997-2023)

Supplementing Mg to dairy cows is widely practised in New Zealand. Various methods are used including drenching, pasture dusting, water trough treatment and adding to hay, silage and other feedstuffs (Young et al., 1979). Fertiliser Mg (calcined magnesite, MgO) is widely used to maintain soil Mg status but research has shown that using fertiliser Mg to achieve good soil, pasture and animal Mg status requires large inputs of Mg (120 kg/ha) and maintaining blood serum Mg status in dairy cows tends to be short-lived without further animal supplementation (O'Connor et al., 1987). The objective of these experiments was …

Potassium Content And The Balance Between Potassium And Other Minerals And Crude Protein In Forage Can Have A Big Impact On Dairy Cow Health, Hary Eriksson

IGC Proceedings (1997-2023)

Preliminary studies indicated that the mineral balance in forage may affect dairy cow health. A bigger study covering the four most northern counties in northern Sweden was conducted. The objective of this study was to compare data on harvested forage with farm data on milk yield and animal health.

Distribution Of Trace Elements In Plant Parts Of Red Clover (Trifolium Pratense L.), S. Ignjatovic, Z. Lugic, D. Sokolovic, J. Radovic

IGC Proceedings (1997-2023)

There is little information on the distribution of minerals in plant parts although factors affecting mineral content in forages have been well investigated (Fleming, 1973; Whitehead et al., 1985). The aim of this investigation was to determine the trace mineral content in plant parts of different cultivars of red clover (foreign and domestic) and to assess differences between cultivars. The existence of significant differences between cultivars would indicate the possibility of selecting cultivars to satisfy particular animal requirements for minerals.

Use Of Green Sulla Forage For Feeding. 2. Effects On Lamb Carcass And Meat Quality, A. Bonanno, M. L. Alicata, G. Tornambè, F. Mazza, G. Di Miceli, D. Giambalvo

IGC Proceedings (1997-2023)

Diets with 2.5% of condensed tannins (CT) from carob pulp have been showed to reduce lamb carcass weight, yield and fatness, as a consequence of lower digestibility due to strong protein-tannin bonds. Moreover the diets lightened meat colour and negatively affected meat sensory properties (Priolo et al., 2000). There is evidence that some tannin-rich legumes have weaker stability of the protein-tannin complex post-rumen (McSweeney et al., 2001). Since the CT-containing sulla (Hedysarum coronarium L.) demonstrated improved lamb growth performance in comparison with CT-lacking annual ryegrass (Lolium multiflorum Lam. subsp. wersterwoldicum) (Giambalvo et al., 2005), …

Use Of Green Sulla Forage For Feeding. 1. Effects On Lamb Growth And Gastrointestinal Nematode Parasite Infestation, D. Giambalvo, A. Di Grigoli, M. L. Alicata, B. Formoso, A. S. Frenda, P. Trapani

IGC Proceedings (1997-2023)

Recent studies have shown that some forage legumes containing condensed tannins (CT), such as sulla (Hedysarum coronarium L.), can reduce the gastrointestinal nematode burden in sheep (Niezen et al., 1998) and increase post-ruminal protein availability (Waghorn et al., 1994). This study aimed to evaluate the anthelmintic and nutritional properties of sulla forage in relation to its CT content. Thus, the growth performance and the level of nematode infestation of lambs fed sulla were compared with those of lambs fed ryegrass (Lolium multiflorum Lam. subsp. wersterwoldicum), lacking in CT.

Leaf, Pod And Whole Plant Tannin Contents In Pigeon Pea (Cajanus Cajan (L.) Millsp), Rodolfo Godoy, P. M. Santos, Francisco H. D. Souza

IGC Proceedings (1997-2023)

Tannin content is an important characteristic of leguminous crops and it has been used as a selection criterion in pigeon-pea improvement programmes (Godoy et al., 1994). In south-eastern Brazil, pigeon pea is often consumed by bovines in the dry season (from April though October), after flowering occurs, and is recommended in some cases, specifically for that time of the year (Lourenço et al., 1994). Since tannin content is being used as a selection criterion and the animals in the dry season preferentially eat pods and leaves, an experiment was conducted to compare whole plant, leaf and pod tannin …

Cry1 Expression During Postnatal Development Is Critical For The Establishment Of Normal Circadian Period, Aaron Schirmer, Vivek Kumar, Andrew Schook, Eun Joo Song, Michael S. Marshall, Joseph S. Takahashi

Biology Faculty Publications

The mammalian circadian system generates an approximate 24-h rhythm through a complex autoregulatory feedback loop. Four genes, Period1 (Per1), Period2 (Per2), Cryptochrome1 (Cry1), and Cryptochrome2 (Cry2), regulate the negative feedback within this loop. Although these proteins have distinct roles within the core circadian mechanism, their individual functions are poorly understood. Here, we used a tetracycline trans-activator system (tTA) to examine the role of transcriptional oscillations in Cry1 and Cry2 in the persistence of circadian activity rhythms. We demonstrate that rhythmic Cry1 expression is an important regulator of circadian period. We then define a critical period from birth to postnatal day …

Department of Nutrition and Health Sciences: Faculty Publications

The sudden outbreak of the COVID-19 pandemic posed a great threat to the world’s healthcare systems. It resulted in the development of new methods and algorithms for the diagnosis and treatment of both COVID-19 and its complications. Diagnostic imaging played a crucial role in both cases. Among the most widely used examinations are transthoracic echocardiography (TTE) and computed tomography angiography (CTA). Cardiovascular complications in COVID-19 are frequently associated with a severe inflammatory response, which results in acute respiratory failure, further leading to severe complications of the cardiovascular system. Our review aims to discuss the value of TTE and CTA in …

Evaluating Assessment Score Validity And Characterizing Undergraduate Biology Exam Content, Crystal Uminski

School of Biological Sciences: Dissertations, Theses, and Student Research

The landscape of undergraduate biology education has been shaped by decades of reform efforts calling for instruction to integrate core concepts and scientific skills as a means of helping students become proficient in the discipline. Assessments can be used to make inferences about how these reform efforts have translated into changes in department curriculum and course practices. Such changes can be measured using student scores on researcher-developed programmatic and concept assessments. Scores on these assessments are often assumed to be accurate representations of student biology content knowledge, but my work indicates that the validity of these interpretations may be threatened …

Measuring The Physiological Effects Of Methylobacterium Oryzae Foliar Inoculation Onto Salt-Stressed Tomatoes Grown In A Greenhouse Semi-Hydroponic System, Collin Dice

Master of Science in Integrative Biology Theses

Salinity stress has been shown to improve hydroponic produce quality such as that of tomato but at the trade-off of produce yield. In order to improve demand for hydroponic produce, techniques that improve salinity tolerance could offset declines in yield without altering the improved quality of produce. In two separate trials, we tested whether foliar inoculation of the ACC deaminase-producing bacteria Methylobacterium oryzae CBMB20 improved salt tolerance in tomatoes grown in a semi-hydroponic system using an indeterminate variety exposed to 26mM NaCl (Trial 1) and a determinate variety exposed to 17mM NaCl (Trial 2). We also tested how salinity and …

Evaluating Nutrient Loading From Agricultural Sources And The Biogeochemical Cycling Capacity Of Environments Connected To Agricultural Lands In Southwestern Ontario, Savannah Knorr

Electronic Theses and Dissertations

Southwestern Ontario is dominated by agricultural lands that are extensively tile drained throughout the region as a management practice to remove excess water from fields. While tile drainage is a common practice, the implementation of constructed preferential flow paths, along with surface runoff from agricultural lands, increases nutrient loading risks to connected and downstream environments, and receiving large lakes. Of particular concern in this region is Lake Erie which has a legacy of severely degraded water quality due to excess nutrient loading from agricultural lands within the lake’s drainage basin. While agricultural lands are a known source for nutrient loading, …
