Understanding Functional Benefits Of Isoleucine And Arginine On Poultry Performance And Health., Roshan Adhikari, Jason T. Lee, Keith Haydon

Proceedings of the Arkansas Nutrition Conference

Poultry industry is rapidly moving towards utilizing the best ingredients to precisely feed the birds for better performance, welfare, health, and profitability. One of the practices that evolved over time with research is better optimization of amino acid utilization in the diets thus changing the crude protein landscape. Historically, if we compare the modern diets to diets from 1980, significant changes are visible in the use of unbound or crystalline amino acids leading to reduced levels of CP and reduced unutilized nitrogen in the diets. Multiple feed-grade amino acids are available in a cost-effective manner in poultry diets. Multiple research …

State Of The Art Pullet And Breeder Nutrition, Rick Van Emous

Proceedings of the Arkansas Nutrition Conference

During the last six to seven decades, broilers have been successfully selected for maximum growth and feed efficiency (Zuidhof et al., 2014). Modern fast-growing broilers reach a body weight of 2.0 to 2.5 kg in 35 to 45 days with an average daily growth of 55 or more gram a day (Augère-Granier, 2019). In a study with different broiler strains representative of broilers in 1957 or 1978 were compared with a broiler strain from 2005 (Zuidhof et al., 2014). The 2005 strain showed, over a 56-day growth period, a 4.6 times higher growth rate and a 50% lower feed conversion …

Broiler Breeder Males: Feed And Nutrition Discussion, Benton Hudson

Proceedings of the Arkansas Nutrition Conference

The methods for feeding broiler breeder males have evolved over recent decades, and further revisions will likely be needed as males become more challenging to manage. Since the introduction of separate male feeding systems in the early 1980’s, breeder males’ nutrient needs have been better managed via daily feed restriction. If a breeder operation can effectively produce, haul, and store a separate male diet, then it provides more options to use different nutrient levels or feed additives that are designed to enhance fertility. This article will outline the history of male-separate feeding and revisit nutritional research on fertility of broiler …

Application Of Nutritional Immunology In The Mitigation Of Economic And Production Losses In The Poultry Industry Associated With Food-Borne Pathogens, Coccidiosis, And Necrotic Enteritis., Shahna Fathima, Ramesh K. Selvaraj

Proceedings of the Arkansas Nutrition Conference

Sub-therapeutic doses of antibiotics were used in poultry production since the 1950s for improved production, prophylaxis, and animal welfare. Extensive and indiscriminatory use of antibiotics led to the emergence of antibiotic resistance in food-borne pathogens of public health significance (Jones & Ricke, 2003). As per the United States Centre for Disease Control, more than 2.8 million infections in 2019 were caused by multidrug resistant bacteria. Due to public health concerns, the use of antibiotic growth promoters in livestock production was prohibited by Sweden and Denmark in 1986 and 1998 respectively (Hammerum et al., 2007). The European Union banned the use …

Using Poultry To Enhance Food Security In Stann Creek, Belize, Emily Spatz, Lisa S. Wood

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

Food insecurity is a growing issue in developing and developed countries alike, and in countries like Belize, the prevalence of hunger has soared in recent years. Not having access to diets with sufficient calories and nutrients leads to a host of developmental issues, including stunting and cognitive delays. The purpose of this work was to create an all-encompassing manual for small-scale poultry production in order to provide nourishment for the students and staff of a school in Belize. After determining that the best way to meet the school’s needs was through dual-purpose birds, background research was conducted to determine small-scale …

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 …

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 …

Rearing Orphan Kangaroos, G L. Ward

Journal of the Department of Agriculture, Western Australia, Series 4

LICENCES are required in Western Australia if certain kangaroos and all species of wallabies are kept in captivity, but orphaned young joeys often need care and hand feeding before they can be released to fend for themselves.

A Guide To Pig Feeding, P Mcnamara

Journal of the Department of Agriculture, Western Australia, Series 4

FOOD is by far the greatest cost in pig production, accounting for between 60 per cent, and 75 per cent, of the total cost, and for this reason it is important that the basic principles of feeding be understood.

Don't Neglect Those Dry Cows, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

WHEN a dairy cow becomes pregnant she is normally milking and has some months to go before being dried off.

It is usual at this stage for dairy farmers to provide the best feed available.

How Much Food Should I Give My Dog?, F C. Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

THIS is a question which every veterinary surgeon has heard hundreds of times, and one that it is impossible to answer in general terms because dogs differ so much in their food requirements and because the nutrient values of various foodstuffs vary considerably.

The Care Of The Breeding Sow, P C. Beck

Journal of the Department of Agriculture, Western Australia, Series 4

PIG-RAISING is a specialised field of animal production, which, to be profitable must incorporate both a scientific and a practical approach.

These two factors must be complementary, for without a sound practical approach, the value of the scientific principles involved, e.g., in breeding and compounding rations would accordingly be reduced.
