Understanding Corn Variability, Edgar O. Oviedo-Rondón

Proceedings of the Arkansas Nutrition Conference

Corn is the most common feed ingredient used in poultry nutrition. Maize contributes with up to 65% of the metabolizable energy and 20% of crude protein in poultry diets (Gehring et al., 2013; Dei, 2017). Its average nutritional value is well-known, but it is accepted that the variability in its composition and energy value is a very common issue with great impact on poultry performance and health (Cowieson, 2005; Gehring et al., 2013; Latham et al., 2016; Montanhini-Neto et al., 2017). Corn variability affects growth, feed conversion, flock uniformity, digestibility, AMEn, digesta viscosity, gut microbiota composition, …

Assessing Dietary Branched-Chain Amino Acids To Achieve Linear Programming Goals Through Model Extrapolation And Empirical Research, Craig W. Maynard, Ed E. Gbur, Vinh-Loi Ly, Minh-Duc Le, Thi H. Ngan Le Jr, Justina Caldas, Michael T. Kidd

Proceedings of the Arkansas Nutrition Conference

Renewed interest, especially in the United States, has sparked in assessing branched-chain amino acid interactions in practical diets for broilers. Indeed, as L-valine enters formulation bird nitrogen excesses are reduced as diet protein falls to the new first limiting amino acid (e.g., isoleucine, arginine, or tryptophan). For a United States based example, the result is less oilseeds and more gains, which typically result in increased inclusions in corn or corn by-products, coupled with a concomitant increase in dietary leucine. The proceedings outline the foundations of the branched-chain amino acid early research, antagonism studies, and a meta-analysis conducted on publications with …

Sustaining Competitiveness In Times Of Uncertainty And Volatility: A Latin American Perspective, Antonio Kalinowski

Proceedings of the Arkansas Nutrition Conference

The poultry industry has dominated the dynamic livestock sector in Latin America during the last decades, doubling production in the last 20 years (Williams and Anderson, 2019). In the future, poultry production in the region is expected to grow at almost twice the annual global rate: 2.5% and 4.0%, respectively. The rapid expansion of the industry has been fueled by the growing consumer demand for chicken meat and eggs, given its price competitiveness and culinary preference in most Latin American countries. Per capita chicken consumption is among the highest in the world (on average ca. 30 kg/person/year), and represents above …

Amino Acid Responses In Conventional And Slow Growing Broilers, Alex Corzo, Marcelo Silva

Proceedings of the Arkansas Nutrition Conference

Conventional and slow-growing broilers are both quite responsive to dietary amino acids. However, when reducing dietary balanced protein (BP), the change in rate of gain on the slower-growing broilers results in a growth curve that is not as steep as it would be if using the current conventional broiler. Amino acid supply and balance, in combination with manipulation of dietary energy density, could enable customers to achieve the desired rate of gain when using slow-growing broilers, depending on the Global Animal Partnership or other certification level the integrator is aiming for.

Heat Damage, Maillard Reactions, And Measurement Of Reactive Lysine In Feed Ingredients And Diets, Maryane S. F. Oliveira, Charmaine D. Espinosa, Hans H. Stein

Proceedings of the Arkansas Nutrition Conference

Feed cost represents 70% of the total cost of poultry and pork production (Patience et al., 2015); therefore, a number of processing techniques have been developed to maximize utilization of nutrients in feed ingredients and diets for optimum animal growth performance. Oilseed meals are commonly exposed to varying degrees of heat to remove solvents used during oil extraction, increase nutrient digestibility, improve storage life, and to reduce anti-nutritional factors (Liener, 1994; Rehman and Shah, 2005; Goebel and Stein, 2011). Heat is also applied in the production of distillers dried grains with solubles (DDGS) from dry grind ethanol facilities …

Practical Pullet And Breeder Nutrition, David J. Burnham

Proceedings of the Arkansas Nutrition Conference

Modern meat chicken breeding stock have been selected for extremely efficient conversion of feed into protein and rapid growth. As a result, it has become increasingly more difficult to rear pullets and breeders to achieve the healthy chick numbers needed to supply the ever-expanding poultry meat market. There are many factors involved in producing a healthy pullet and breeder chicken. These include; housing, lighting, temperature and air control, health, animal husbandry, feed management and nutrition. This presentation is titled, Practical Pullet and Breeder Nutrition. Feed nutrient composition is important, but feed management is critical to make the nutrition effective. The …

Dietary Fiber From Crude To Refined: Unraveling Its Value On Animal Performance, Gilson Gomes, Tara York, Xavière Rousseau

Proceedings of the Arkansas Nutrition Conference

Fiber, although a simple five letter word, is like an onion. It is only once you begin to peel back the layers that you discover the complexity within. As nutritionists we are used to thinking in terms of ‘crude fiber’, but as we move into a world without antibiotics and the need to sometimes select alternative ingredients, we are now beginning to separate fiber into its chemical components and functional properties. To understand the functional properties, such as solubility and fermentability, we first need to ensure we can accurately measure the chemical composition of fiber for a wide variety of …

Free Fatty Acid Removal From Oil Using Magnetic Nanoparticles, Daniel Sabo

Proceedings of the Arkansas Nutrition Conference

Unprocessed crude oils consist of some amount of triglycerides as well as free fatty acids (FFAs). FFAs are virtually absent in oils from living tissue. They are formed by enzymatic action after the animal has been slaughtered. Hydrolysis of ester bonds in lipids, which results in the formation of FFA from the triglycerides, may be caused by enzymatic action, heat, or moisture. This release of short-chain fatty acids is the reason for rancid flavor and odor. Furthermore, the presence of FFAs can self-catalyze and release more FFAs from triglycerides. FFAs are susceptible to oxidation, which leads to oxidative rancidity. This …

Nutrition And Coccidiosis, Po-Yun Teng, Fernanda Castro, Woo Kyun Kim

Proceedings of the Arkansas Nutrition Conference

Coccidiosis is the most common parasitic disease caused by Eimeria spp., leading to over $14 billion economic loss worldwide annually. The most prevalent Eimeria spp. in poultry include E. tenella, E. maxima, E. acervulina, E. brunetti, E. necatrix, E. praecox, and E. mitis and have different level of pathogenicity and specific infection sites in the intestine. Eimeria spp. invade intestinal epithelial tissues and induce intestinal damage, causing inflammation, oxidative stress, hemorrhage, and diarrhea. Furthermore, coccidiosis causes reduction of growth performance, intestinal integrity, nutrient digestibility, and increase of mortality and mobility in poultry. Nutrition strategies have been evaluated to mitigate detrimental …

Every Part Of Yeast Is The Best Part, Matthieu Baulez, Bruno Bertaud, Lisa Saibi

Proceedings of the Arkansas Nutrition Conference

Yeasts are single-cell, eukaryotic microorganisms classified in the fungi kingdom. They are generally around 10μm in size, have a nuclear membrane, a cell wall, and a cytoplasmic content. Yeasts are characterized as heterotrophs, which means they rely on organic material as sources of energy and nutrients. Not all yeasts are equal. There are about 60 genera and about 1,500 species of yeasts. Only a few are used commercially. Thanks to its exceptional fermentative capacities and nutritional properties, Saccharomyces cerevisiae is the main yeast used in food, beverage and baking as well as in animal nutrition. The main types of yeasts …

Mineral Nutrition In Broilers: Where Are We At?, Rick Kleyn, Mariana Ciacciariello

Proceedings of the Arkansas Nutrition Conference

Mineral nutrition remains an essential consideration for broiler nutritionists. The complex interactions between different minerals sources, other ingredients, and the broiler itself, coupled with their relatively low costs, have led to the current status of elevated levels of minerals in broiler diets. New perspectives on sustainability have brought about a rethink of the way we formulate practical diets. There are considerable opportunities for reducing macro minerals such as calcium and phosphorus, particularly for older birds. Our understanding of attaining an ideal dietary cation-anion balance is confused by the lack of clarity in measuring the balance and the bird’s ability to …

Measuring Palatability As A Linear Combination Of Nutrient Levels In Food Items, Jeffrey S. Young

Faculty & Staff Research and Creative Activity

It well known that palatability and nutritional quality of foods and/or diets are viewed as being in tension with one another. While there exist multiple measures of healthiness, there are no such measures for tastiness. This gap limits the degree to which researchers can investigate this tension and its implications for dietary behavior and hence public health and nutrition policy. The scope of future work concerning the dietary behavior of Americans would expand greatly if researchers better understood consumers’ willingness to eat certain foods, which matters as much as recommending those foods for them to eat in the first place. …

Weight Status Perceptions And Food Choice, Christopher R. Gustafson

Cornhusker Economics

Does your weight status—whether your height and weight put you into the normal weight, overweight, or obese category—predict your food choices, or even the types of food you’ll pay attention to when making a choice? What about the weight status you perceive yourself to be? These are important questions because the percentage of the population that is overweight or obese in the U.S.—and world-wide—has been increasing for decades despite a wide range of efforts aimed at slowing/reversing its growth. In the U.S., over 70 percent of the population is overweight or obese. High body weight has numerous consequences for individuals …

Challenges And Benefits Experienced By Mississippi Schools In The Adoption Of Farm To School Programs, Manuel Aldair Franco Pech

Honors Theses

Mississippi obesity rates are the second highest in the United States. An appropriate target group to combat the state’s high obesity rates are school age children (ages 18 and under), because healthy eating habits developed at this age translate into adult years. An avenue to encourage and develop healthy eating habits are Farm to School (F2S) programs, which provide in-school accessibility to healthy, locally produced foods. The objective of this study was to analyze the results from the 2015 United States Department of Agriculture’s (USDA) F2S Census, which collected details regarding F2S participation across the country, to determine the benefits …

Buy Fresh, Buy Local: Nebraska Working Together For Local Food, Margaret Milligan

Cornhusker Economics

Direct market farms in Nebraska are made up of people passionate about raising good food for their fellow Nebraskans. They grow vegetables, fruits, meat, grains, and value-added products to sell directly to consumers in their communities.

During the pandemic, these small farms have experienced restaurant sales vanishing, farmers’ market attendance de-creasing, and slots filling up at the small meat processors where they take their livestock. At the same time, there has been a renewed interest from consumers seeking reliable, transparent food produced close to home. It’s been a volatile year, and it has required quick pivoting, group coordination and action …

Monocyte Abundance And White Blood Cell Expression Of Prolactin And Nf-Kb Pathway Genes In Beef Steers Are Altered By Grazing Toxic Endophyte-Infected Tall Fescue And Lipopolysaccharide Challenge, Cecilia Winfrey

Theses and Dissertations--Animal and Food Sciences

Experiment 1 tested the hypothesis that ad libitum consumption of a 1:1 blend (MIX) of sodium selenite (ISe) and SELPLEX vs solely ISe as selenium (Se) supplements (27 ppm) in a vitamin-mineral mix (V-M) by steers subjected to summer-long grazing of toxic endophyte-infected tall fescue (TE) would ameliorate the negative effects of TE by positively affecting the expression pattern of prolactin (PRL) and NF-kB pathway genes by circulating leukocytes (WBC). Experiment 2 tested the hypothesis that the MIX form of supplemental Se also would ameliorate the negative effects of in vitro blood lipopolysaccharide challenge (LPS) on WBC gene expression. The …

Willingness-To-Pay For Halal And Branded Poultry In Northern Mozambique, Alison J. Creasey, L. Lanier Nalley

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

While price typically drives consumers’ food-purchasing decisions in low-income countries, religious attributes associated with food production and corporate branding could influence buying patterns. In Mozambique, more than 46% of people were living below the poverty line of ($0.31 USD) per day in 2018. That being said, in the Nampula Province (the location of this study), which is the second poorest province in the country, over 25% of the population is Muslim and may be willing-to-pay (WTP) a premium for Halal meat products to uphold Islamic beliefs. Like many parts of sub-Saharan Africa, poultry is the fastest-growing source of protein. Since …

Energy And Amino Acid Metabolism In Lactating Jersey Cows Consuming Feed Byproducts, Kyle Alvin Mclain

Department of Animal Science: Dissertations, Theses, and Student Research

Animal protein byproducts are high bypass proteins commonly used in the dairy industry. These bypass proteins can escape the rumen to supply additional amino acids needed to support milk and protein yield. Two of the more popular animal protein byproducts used in the dairy industry are blood meal and hydrolyzed feather meal. In the first experiment, two flow meters were compared using headbox-style calorimeters. The objectives of the first study were to test mass flow meter (MFM) and volumetric flow meter (VFM) by measuring O₂ consumption and CO₂ production and to illustrate the effects of incomplete gas recovery …
