Recent Findings On Phosphorus Digestibility Of Feed Ingredients In Broilers, Jay Hampton, Wenting Li, Franco Mussini, Katie Hilton, Janet Remus, Samuel J. Rochell
Recent Findings On Phosphorus Digestibility Of Feed Ingredients In Broilers, Jay Hampton, Wenting Li, Franco Mussini, Katie Hilton, Janet Remus, Samuel J. Rochell
Proceedings of the Arkansas Nutrition Conference
Accurately meeting the dietary P needs of broilers is critical to ensure optimal bird performance, health, and welfare without causing undue environmental burdens associated with excess dietary P excretion. Phosphorus is commonly supplied in broiler diets from inorganic phosphates derived from non-renewable sources, but it has been estimated that peak P production will occur between 2030-2040 and that the global supply of P could be depleted within this century (Cordell and Drangert, 2009; Nest and Cordell, 2012). To address these concerns, inorganic P use in agriculture, including use in broiler diet formulation, requires careful stewardship. To this end, the dietary …
Recent Advancements On Calcium And Phosphorus Recommendations In Broilers, Justina Caldas, Marcelo Silva
Recent Advancements On Calcium And Phosphorus Recommendations In Broilers, Justina Caldas, Marcelo Silva
Proceedings of the Arkansas Nutrition Conference
Calcium and phosphorus have been recognized essential nutrients in chickens since 1950’s (Lesson & Summers, 2001) playing important roles in bone development, among other functions. Calcium is assumed an inexpensive nutrient in animal least cost formulation while phosphorus is considered expensive and scant. The actual economic impact comes from the influence of calcium on phosphorus requirements, changes in phosphorus digestibility, buffer capacity, gut health, trace mineral absorption, fat digestibility, welfare traits, etc. Both minerals have important interactions to be considered during formulation. Few changes have been made over the past 20 years to calcium and phosphorus recommendations because these values …
Limestone Solubility: What Can You Do About It?, Wenting Li, Katie Hilton, Franco Mussini, Janet Remus
Limestone Solubility: What Can You Do About It?, Wenting Li, Katie Hilton, Franco Mussini, Janet Remus
Proceedings of the Arkansas Nutrition Conference
Calcium (Ca) is essential for bone development mineralisation, as well as for eggshell formation, muscle and neural functions. Depending on the type of diets (veggie vs. non-veggie), species (turkey, chicken, duck), and age of animal (young vs. adult), limestone can contribute up to 95% total Ca in the final diet, with more Ca from limestone for younger animals with veggie diet. Despite the significant contribution of limestone to total diet Ca levels, the bioavailability variation of limestone Ca is rarely considered. Phosphorus (P) is a limited resource and is the third most costly ingredient in poultry …
Mineral Nutrition In Broilers: Where Are We At?, Rick J. Kleyn, Mariana Ciacciariello
Mineral Nutrition In Broilers: Where Are We At?, Rick J. 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 …
Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty
Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty
Animal Science Undergraduate Honors Theses
This study will focus on how maternal phosphorus status of beef heifers affects the growth and performance of their calves. Heifers have been offered free-choice mineral with either 0 or 4% supplemental phosphorus from 30 days after weaning until calving. A study by H. Hilfiker, a University of Arkansas honors student, investigated the effects of these treatments from 30 days after weaning until 60 days after the breeding season when heifers were confirmed to be bred or open. For this developing heifer project 64 crossbred Angus heifers were assigned randomly into 8 groups (8 heifers/ group) before assigning each group …
Impact Of Phosphorus Intake On Beef Heifer Growth Performance And Conception Rates, Hailey Hilfiker, Beth Kegley, Rick Rorie, Jeremy Powell
Impact Of Phosphorus Intake On Beef Heifer Growth Performance And Conception Rates, Hailey Hilfiker, Beth Kegley, Rick Rorie, Jeremy Powell
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
In Northwest Arkansas, soil phosphorus concentrations have increased where livestock manures have been repeatedly applied, leading many to question if supplementing phosphorus in this area is necessary. The effects of phosphorus intake on beef heifer growth performance and conception rates were investigated. In this study, crossbred Angus heifers (n = 72), approximately 30 days after weaning, were stratified by body weight (average initial weight 251 ± 3.9 kg) and allocated randomly into 8 groups. Groups were assigned randomly to 1 of 2 treatments. Treatments were delivered through either a free-choice-mineral mix that contained no supplemental phosphorus (CON), or a free-choice-mineral …
Novel Biomarkers For Calcium And Phosphorus Metabolism In Breeder Hens And Broilers, Andrew Dick Magnuson
Novel Biomarkers For Calcium And Phosphorus Metabolism In Breeder Hens And Broilers, Andrew Dick Magnuson
Graduate Theses and Dissertations
Broiler breeder hens are subject to the dual expectation to not only maintain a high production of eggs for an extended time period, but to produce eggs which can support the life of chicks which will be used for either meat production or as parent stock. Egg fertility and hatchability are heavily influenced by the thickness of the egg shell, the mineral calcium carbonate shell of the egg necessary for protecting the embryo growing inside. Many factors affect egg shell quality including age of the hen, diet, environmental conditions, genetic strain, stress, disease, and nutrition. Laying hens will mobilize calcium …

Historical Research Bulletins of the Nebraska Agricultural Experiment Station
1. The nitrogen, calcium, and phosphorus content of 127 newly hatched chicks was determined. 2. Thirty newly hatched chicks were fed accurately known amounts of a good chick mash for 60 days. At the end of the period nitrogen, calcium, phosphorus, and fat were determined for each chick. 3. By means of the comparative slaughter test the retention of nitrogen was found to be 37.8 per cent, calcium 43.4 per cent, and phosphorus 27.3 per cent of the respective elements fed. 4. The average gain in live weight per gram of nitrogen fed was 12.0 grams. 5. The rate of …
