Antibiotic resistance is a global health threat and often results from new mutations. Antibiotics can induce mutations via mechanisms activated by stress responses, which both reveal environmental cues of mutagenesis and are weak links in mutagenesis networks. Network inhibition could slow the evolution of resistance during antibiotic therapies. Despite its pivotal importance, few identities and fewer functions of stress responses in mutagenesis are clear. Here, we identify the Escherichia coli stringent starvation response in fluoroquinolone-antibiotic ciprofloxacin-induced mutagenesis. Binding of response-activator ppGpp to RNA polymerase (RNAP) at two sites leads to an antibiotic-induced mutable gambler-cell subpopulation. Each activates a stress response …

Circadian Clock Control Of Mrtf/Srf Pathway Suppresses Beige Adipocyte Thermogenic Recruitment, Xuekai Xiong, Weini Li, Ruya Liu, Pradip Saha, Vijay Yechoor, Ke Ma Apr 2023

Circadian Clock Control Of Mrtf/Srf Pathway Suppresses Beige Adipocyte Thermogenic Recruitment, Xuekai Xiong, Weini Li, Ruya Liu, Pradip Saha, Vijay Yechoor, Ke Ma

Faculty, Staff and Students Publications

The morphological transformation of adipogenic progenitors into mature adipocytes requires dissolution of actin cytoskeleton with loss of myocardin-related transcription factor (MRTF)/serum response factor (SRF) activity. Circadian clock confers temporal control in adipogenic differentiation, while the actin cytoskeleton-MRTF/SRF signaling transduces extracellular physical niche cues. Here, we define a novel circadian transcriptional control involved in actin cytoskeleton-MRTF/SRF signaling cascade that modulates beige fat thermogenic function. Key components of actin dynamic-MRTF/SRF pathway display circadian regulation in beige fat depot. The core clock regulator, brain and muscle arnt-like 1 (Bmal1), exerts direct transcriptional control of genes within the actin dynamic-MRTF/SRF cascade that impacts actin …

The relationship between depression and post-COVID-19 disease syndrome (post-COVID-19 syndrome) is established. Nevertheless, few studies have investigated the association between post-COVID-19 syndrome and mixed depression, i.e., a specific sub-form of depression characterized by high level of excitatory symptoms. Aims of the present study are: (a) to compare the post-COVID-19 syndrome's burden in depressed and non-depressed patients, and (b) to investigate the correlation between post-COVID-19 syndrome's burden and the severity of mixed depression. One thousand and forty six (n = 1460) subjects with post-COVID-19 syndrome were assessed. Subjects were divided into those with (DEP) or without (CONT) depression. Sociodemographically, post-COVID-19 syndrome's …

Hybrids Between Meadow And Smooth Bromegrass: A New Forage Crop For Canada, B. E. Coulman, Y. S. N. Ferdinandez Apr 2023

Hybrids Between Meadow And Smooth Bromegrass: A New Forage Crop For Canada, B. E. Coulman, Y. S. N. Ferdinandez

IGC Proceedings (1977-2023)

Smooth bromegrass (Bromus inermis Leyss.) has been an important hay grass in the agricultural regions of western Canada for approximately 50 years. Meadow bromegrass (B. riparius Rehm.) has become the most important pasture species in this region over the last 15 years. It is possible to produce hybrids between these species, which could lead to the development of a type of bromegrass which would be useful for both hay and pasture purposes.

Liveweight Gain Of Lambs Grazing Six Short-Term Ryegrass Cultivars, W. W. Nichol, M. G. Norriss Apr 2023

Liveweight Gain Of Lambs Grazing Six Short-Term Ryegrass Cultivars, W. W. Nichol, M. G. Norriss

IGC Proceedings (1977-2023)

Increasing dry matter (DM) production per ha is a key goal in ryegrass (Lolium) breeding programmes (Easton et al., 2002), based on the assumption that increased DM yield will in turn increase profitability per ha, through an increase in animal productivity. However, the performance of animals grazing pasture can also be modified by the quality of the forage on offer, and the presence of toxins within the pasture. The objective of this study was to compare the liveweight gain per hectare of lambs grazing six short-term ryegrasses, which had been selected for various combinations of improved DM …

Economic Comparison Of Pasture Based Lamb Production Systems In Southern Australia, A. J. Kennedy, A. N. Thompson Apr 2023

Economic Comparison Of Pasture Based Lamb Production Systems In Southern Australia, A. J. Kennedy, A. N. Thompson

IGC Proceedings (1977-2023)

Lamb production enterprises in southern Australia utilise a pasture base as their primary nutrition source due to its low cost. Holmes Sackett & Associates (2003) identified that increasing total lamb weight per hectare by increasing ewe stocking rate, animal genetic potential and weaning percentage can increase enterprise profitability. The limitation of these enterprises is the seasonal and geographic variations impeding pasture production and quality. The 'MoreLamb Quality Pasture' project is demonstrating the benefits of mixing high performing grass, legume and herb species to extend the pasture-growing season and increase pasture quality. Key economic indicators of three pasture systems and commercial …

The Impact Of Tillage System For Small-Grain Pasture Establishment On The Performance Of Growing Beef Calves In Arkansas, P. Beck, S. Gunter, M. Anders, K. Lusby, D. Hubbell Apr 2023

The Impact Of Tillage System For Small-Grain Pasture Establishment On The Performance Of Growing Beef Calves In Arkansas, P. Beck, S. Gunter, M. Anders, K. Lusby, D. Hubbell

IGC Proceedings (1977-2023)

In the United States, governmental regulations mandate the improvement of farming practices to improve environmental quality. There is a requirement to reduce the siltation of waterways, soil carbon losses, and nutrient runoff along the Mississippi River Delta. The use of small-grain forages by grazing cattle offers real opportunities to produce high-quality forage for cattle production during the winter and spring months. No-till and reduced tillage practices developed primarily for grain production may offer environmental and economic solutions for both grain farmers and cattle producers. Producers are slow to adopt conservation tillage practices because of a perceived risk of reduced production. …

Urea Applied To Puccinellia-Based Pastures Increases Pasture And Sheep Production, M. L. Hebart, N. J. Edwards, A. D. Craig, E. A. Abraham, J. D. Mcfarlane, J. E. Hocking Edwards

IGC Proceedings (1977-2023)

In the 1950's large areas of native vegetation in the upper south east of South Australia (SA) were replaced with highly productive Hunter River lucerne. This maintained groundwater recharge at near pre-clearing levels. The area of lucerne was reduced dramatically in the late 1970's by a combination of lucerne aphids, wingless grasshoppers and drought. In 1981 severe flooding inundated large areas of the region, causing the saline groundwater to rise to the soil surface. Since that time, dryland salinity has been a feature of the local farming system and salt-tolerant pastures based on puccinellia (Puccinellia ciliata) were widely …

Sustainability Of Beef, Dairy And Goat Production With Batiki Grass (Ischaemum Aristatum Var. Indicum) In The Dry Season In Samoa, E. M. Aregheore Apr 2023

Sustainability Of Beef, Dairy And Goat Production With Batiki Grass (Ischaemum Aristatum Var. Indicum) In The Dry Season In Samoa, E. M. Aregheore

IGC Proceedings (1977-2023)

Batiki grass (Ischaemum aristatum var. indicum) was introduced to Samoa from Fiji in the early 1970s to complement other existing natural or unimproved grasses and is now the most common propagated pasture grass in Samoa. The contrast between the wet and the dry seasons has a great impact on the nutritive value of batiki grass. Aregheore (2002) observed reduced growth rate, poor body condition score and low performance in steer calves and goats offered batiki as the sole diet during the dry season. This paper reports on the sustainability of beef, dairy and goat production with batiki grass …

Whole Crop Cereal Silage In Dairy Production, J. Wallsten, L. Ericson, K. Martinsson Apr 2023

Whole Crop Cereal Silage In Dairy Production, J. Wallsten, L. Ericson, K. Martinsson

IGC Proceedings (1977-2023)

Whole-crop cereal silages (WCCS) are used to some extent in Sweden, but knowledge about the use of this feed for high yielding dairy cows is scarce. The crop is often harvested at different stages of maturity, from heading to yellow ripeness, which gives forages that differ in chemical composition. The purpose of this trial was to compare intake and milk production of dairy cows fed a WCCS based on barley harvested at three different stages of maturity.

Effect Of Potato Pulp Silage Supplementation On Milk Production In Cows Grazing Temperate Pasture, Masaaki Hanada, Y. Aibibula, D. Okumura, Meiji Okamoto Apr 2023

Effect Of Potato Pulp Silage Supplementation On Milk Production In Cows Grazing Temperate Pasture, Masaaki Hanada, Y. Aibibula, D. Okumura, Meiji Okamoto

IGC Proceedings (1977-2023)

In a dairy farming system based on pasture in Japan, maize grain is generally used as an energy source for milking cows, with almost all grain been imported. Potato-pulp is one of the agricultural by-products derived from the starch industry in the northern island of Japan. In our previous study (Aibibula et al., 2004), it was demonstrated that potato pulp could be preserved for a long time by ensiling without additives, and that the digestible energy value of potato pulp silage (13 MJ/kg DM) was almost the same as beet pulp. From these results, it is possible that some …

Weight Gain Of Nellore X Red Angus, Holstein X Zebu, And Nellore Steers Supplemented On Brachiaria Brizantha Cv. Marandú Pasture, R. A. Reis, D. Freitas, F. L. Fregadolli, L. M. A. Bertipaglia, T. T. Berchielli, K. T. De Resende, D. S. Ferreira, A. G. Caselli

IGC Proceedings (1977-2023)

Supplementation is a very efficient approach for improving animal performance and gain/ha in grazing systems in tropical conditions. However, care needs to be taken to avoid substitution effects (Moore et al., 1999). Results may also depend on animal genetics and the availability and nutritional value of forage. This trial aimed to evaluate different levels of supplementation using steers from different genetic groups on palisade grass (Brachiaria brizantha cv. Marandú) pasture during the rainy season.

Suitability Of Selenate Containing Silage Additives For The Supply Of Beef Cattle, Harald Laser Apr 2023

Suitability Of Selenate Containing Silage Additives For The Supply Of Beef Cattle, Harald Laser

IGC Proceedings (1977-2023)

Selenium concentrations in herbage are frequently insufficient (< 100 μg Se/kg dry matter (DM)) to meet the requirements of ruminants. Whereas increasing Se supply by feeding mineral mixtures is a reliable method to prevent Se deficiencies for dairy cows, adequate Se supplementation is more difficult to achieve in extensive systems (McDowell, 1996). A suitable measure could be the addition of Se to herbage before ensiling.

West African Dwarf Goat Response To Supplementary Feeding In Cameroon, E. Tedonkeng Pamo, B. Boukila, F. Tendonkeng, J. R. Kana Apr 2023

West African Dwarf Goat Response To Supplementary Feeding In Cameroon, E. Tedonkeng Pamo, B. Boukila, F. Tendonkeng, J. R. Kana

IGC Proceedings (1977-2023)

The production of the West African Dwarf goat (WADG) in Cameroon is very low, because of lack of proper nutrition. Nitrogen content is generally very low and fibre content is high, both in the grass and the crop residues which form the basis of their diet particularly during the dry season. Supplementation of these roughages is a promising way of alleviating nutrient deficiencies. Different types of supplementary feeding have been advocated to boost goat production (Leng, 2003), of which supplementary feeding with leguminous tree leaves is of high merit. The present study was undertaken to evaluate the effects of supplementary …

New Advance In Forage Production And Dairy Industry In China, Zhiqiang Q. Li, J. G. Han

IGC Proceedings (1977-2023)

There were 6.9 million dairy cows in China in 2002 with milk yield of 13 million t. These values were 21.4 and 26.7% higher respectively than in 2001. Milk yield per cow was 1891 kg, 4.4 % higher than in the previous year, but still one third lower than the world average. Milk fat and protein contents were about 3.2 and 3.0 % respectively, a little below the world average. Milk consumption was 10.9 kg per person, much lower than the world average (97.6 kg) So, although great changes have taken place in dairy breeding, forage production and disease control, …

Productivity Of Sahiwal And Friesian-Sahiwal Crossbreds In Marginal Grasslands Of Kenya, W. B. Muhuyi, F. B. Lukibisi, S. N. Ole Sinkeet Apr 2023

Productivity Of Sahiwal And Friesian-Sahiwal Crossbreds In Marginal Grasslands Of Kenya, W. B. Muhuyi, F. B. Lukibisi, S. N. Ole Sinkeet

IGC Proceedings (1977-2023)

Dual-purpose cattle can be used to exploit the production potential of semi-arid grasslands of Kenya for milk and meat production. Although the Sahiwal is adapted to these grasslands, its productivity is low. In order to increase milk and meat productivity, the Sahiwal has been crossed with the Friesian to produce Friesian-Sahiwal crossbreds (McDowell et al., 1996) adapted to the tropical environment. The objective of this study was to evaluate the productivity of Sahiwal and Friesian-Sahiwal crossbreds.

The Effects Of A High Grass Input Feeding System Compared To High Concentrate Input Feeding System Offered To Spring Calving Dairy Cows In Early Lactation, E. Kennedy, M. O'Donovan, J. P. Murphy, F. P. O'Mara, L. Delaby Apr 2023

The Effects Of A High Grass Input Feeding System Compared To High Concentrate Input Feeding System Offered To Spring Calving Dairy Cows In Early Lactation, E. Kennedy, M. O'Donovan, J. P. Murphy, F. P. O'Mara, L. Delaby

IGC Proceedings (1977-2023)

Grazed grass is the cheapest feed available on Irish dairy farms. The inclusion of grass in the diet of the spring-calving dairy cow in early lactation is recommended. Previous studies focused on introducing grazed herbage into the cows diet in early spring in conjunction with grass silage and concentrate, and compared this to cows fed indoors. The objective of this study was to compare the milk production and feed budget of two contrasting early lactation feeding regimes. One regime was based on a high herbage inclusion with a low concentrate level (HG), while the other was based on a high …

A Comparison Of A Full Time Grazing And A Partial Storage Feeding System, For Dairy Cows, C. P. Ferris, D. C. Patterson Apr 2023

A Comparison Of A Full Time Grazing And A Partial Storage Feeding System, For Dairy Cows, C. P. Ferris, D. C. Patterson

IGC Proceedings (1977-2023)

Partial storage feeding has been adopted by a number of Northern Ireland dairy farmers in recent years. This is due in part to increasing cow numbers, and as such, insufficient pasture close to the milking parlour to permit full time grazing. Partial storage feeding may also have environmental benefits, as well as reducing labour requirements associated with 'droving' and pasture management. In view of this, a study was undertaken to examine animal performance with either a full-time grazing, or a partial storage feeding regime.

Effect Of A Summer Period At Pasture On The Performance Of Young Bulls Offered Concentrates Ad Libitum, R. J. Fallon, M. G. Keane Apr 2023

Effect Of A Summer Period At Pasture On The Performance Of Young Bulls Offered Concentrates Ad Libitum, R. J. Fallon, M. G. Keane

IGC Proceedings (1977-2023)

Holstein bull calves can produce a 250 kg carcass at 11 to 12 months of age on indoor feeding of ad libitum concentrates. An outdoor period at pasture would reduce housing costs. Two experiments were undertaken to determine the effect of an outdoor period at pasture on concentrate intake, liveweight gain and selected carcass traits of Holstein young bulls.

Animal Unit Of Sheep (Zel Breed) Grazing In Mazandaran Grasslands In Iran, Hossein Arzani, Reza Erfanzadeh, S. Farazmand

IGC Proceedings (1977-2023)

Animal unit equivalents (AUEs), provide a means of summarising grazing capacity, calculating stocking rates and other stocking variables (Scarnecchia, 1990). Animal units (AU) are often defined in relation to the dominant animal type in an area In Iran there are 27 sheep breeds which are classified into three main body size classes, namely: small, medium and large. The objective of this experiment was to define animal units, animal and forage requirements for sheep grazing in Mozandaran grasslands.

Mixed Fattening Of Steers And Lambs On Improved Grasslands In Uruguay: I. Pasture Performance, D. F. Risso, Fabio Montossi, E. J. Berretta, R. Cuadro, I. De Barbieri, R. San Julián, A. Dighiero, A. Zarza Apr 2023

Mixed Fattening Of Steers And Lambs On Improved Grasslands In Uruguay: I. Pasture Performance, D. F. Risso, Fabio Montossi, E. J. Berretta, R. Cuadro, I. De Barbieri, R. San Julián, A. Dighiero, A. Zarza

IGC Proceedings (1977-2023)

The use of P fertilisers together with legume broadcasting is a low cost and high impact technology for improving native grassland (Risso et al., 2001). Its use is increasing in Uruguay, although not for mixed grazing, even though this management is a common practice on native grasslands. Good pasture response may occur under mixed grazing when it is adequately managed (Nolan & Connolly, 1989). The following trials characterise pasture response with such management, in Uruguayan conditions.

IGC Proceedings (1977-2023)

In cow-calf operations in Uruguay, mixed cattle and sheep grazing on rangelands is predominant, while fattening is a specialised process. Within certain limits of the lamb/steer ratio and stocking rate, a complementary grazing effect occurs under mixed grazing, improving net results (Nolan & Connolly, 1977; Risso et al., 2002). These trials characterise animal performance under such management.

Constraints On Dairy Cattle Production From Locally Available Forages In Bangladesh, M. A. S. Khan Apr 2023

Constraints On Dairy Cattle Production From Locally Available Forages In Bangladesh, M. A. S. Khan

IGC Proceedings (1977-2023)

The productivity of milk producing animals in Bangladesh is low because of low individual yield and poor fertility. The reasons for the low productivity are complex but, in order of priority, appear to be (a) the imbalanced nature of the nutrients that arise from the digestion of the forage resources, (b) the incidence of disease/parasitism, and (c) the often harsh climatic circumstances. Thus, the purpose of this study was to find out the practical constraints on dairy cattle production from locally available forages under small holding village conditions of Bangladesh.
