This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Total phosphorus (P) in broiler manure has been reduced by decreasing dietary non phytate P (NPP) in combination with added phytase or low phytate (LP) grains. However, few studies have investigated the effects of diet amendment on performance and P excretion from broiler breeders, while the reported effects on water soluble P (WSP) from broilers have been inconsistent. To address this, broiler breeders were fed reduced NPP diets and phytase during the rearing (10-21 wk) and laying (22-64 wk) phase (Chapter 1). Decreasing dietary NPP below 0.37% reduced fertility, which was hypothesized to result from insufficient P intake during rearing. Decreasing NPP in breeder laying diets to 0.19% (no phytase) or 0.09% (with phytase) had no effect on eggs or chicks produced, but reduced manure total P and WSP by 39 to 42%, respectively. Chapters 2, 3, and 4 investigated reduced available P (AvP), phytase, phytate level, and the calcium (Ca):AvP or Ca:NPP ratios in broiler diets on ileal P and amino acid (AA) absorption, P retention, and total P and WSP in manure. Reduced AvP and phytase decreased manure total P. However, manure WSP and the ratio of WSP:total P were controlled by the dietary Ca:AvP ratio. Effects of Ca:AvP on WSP were dependent on the initial dietary phyate level and were mediated by altered phytate hydrolysis, precipitation of CaP complexes and urinary P output. Including LP soybean meal (SBM) in diets decreased total P and WSP by 49% and 56%, respectively, while phytase increased the WSP:total P ratio in manure. Maximum P retention and minimum total P output occurred when the dietary Ca:NPP ratio was 2.34:1 and 2.53:1 in LP and high phytate (HP) SBM diets, respectively. Dietary Ca had no effect on amino acid (AA) absorption in HP SBM but decreased AA absorption in LP SBM diets when Ca was>0.93%. Therefore, while a wider Ca:NPP ratio could decrease manure WSP, this may negatively affect AA absorption when diets contain LP SBM.

This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus is a potential environmental pollutant. The objectives were to minimize fecal phosphorus (P) by optimizing the efficiency of utilization of dietary available phosphorus (aP) for carcass and skeletal growth. In two experiments, Arbor Acres X Arbor Acres male broiler chicks were fed from 0-3 weeks of age a diet adequate in vitamin D, calcium (Ca) and P (National Research Council (NRC) 1994). Experiment 1A assessed body weight gain and whole dry skeletal weight at 2,4,6,and 8 wks of age. Experiment 1B used a central composite, rotatable experimental design with dietary Ca from 0.55% to 0.85% and aP from 0.15% to 0.45% from 4 to 7 wks of age. Decreasing the dietary Ca:aP produced a statistically significant (P

Available in PDF, EPUB and Kindle. Book excerpt: Recent Advances in Animal Nutrition-1981 is a collection of papers that discusses the effects of dietary fat on milk composition, relating it to the biochemistry of fat synthesis in the mammary gland. The influence of concentrates on milk composition as well as the pattern and level of concentrate feeding on milk output are also covered. The book describes the need for better utilization of grass and grass products in dairy production, the mineral and trace element requirements of pigs; the importance of anion-cation balance in poultry diets and its effects on performance levels; and the selenium and cobalt requirements of ruminants. The problems of medicinal residues in animal products and the toxicological effects of aflatoxin residues in animal products are also considered. People involved in agriculture, dairy production and animal nutrition will find the book useful.

Book excerpt: Incorporating research chapters from academic authors around the world, this book focuses on the most recent scientific advances in understanding phytate; both IP6 and its esters. It examines phytate degradation patterns in the gastrointestinal tract, and investigates the relevance of gut microbiome and endogenous phosphatases on phytate breakdown, as well as regulation and functions of inositol diphosphates IP3, IP4, and IP7, IP8. It also identifies recommendations for formulating for minerals and amino acids in the presence of phytate, including the effects of phytase on protein bioavailability, and the impact of digestible Ca and P in both swine and poultry. This leading science and research is coupled with real-world pragmatism, including a focus on what industry stakeholders are currently doing to counter dietary phytate, and an overview of the role of nutrition in respect of bone health, meat quality, welfare, and antibiotic free production. As such, the content is relevant for scientists, nutritionists and producers alike.
