项目摘要

A 3 year study will be conducted to examine long-term benefits for closely meeting changing nutrient requirements of individual sows during gestation and across parities, managed in a group housing system and using computer controlled electronic sow feeders (ESF). The study will comprehensively evaluate sow growth and reproductive performance, welfare, behavior, and body condition when ESF are used to: 1) manage sows by feeding a conventional one -phase feeding program throughout gestation (Control) or 2) daily adjust feeding levels and nutrient to energy ratios for individual sows as nutrient demands change throughout gestation (Precision fed). The latter will be achieved by blending 0.2% SID Lys and 0.8% SID Lys diets in varying proportions based on targeted weight gains. Sow performance, behavior, and weight gain will be monitored throughout lactation along with evaluating pre-weaning piglet performance. The project is designed to monitor sows using ESF for 3 consecutive parities using primiparous sows at the start of the study. Sow progeny performance will be assessed using litters of 10 piglets from 12 Control sows and 12 Precision Fed sows per parity. These piglets will be penned based on individual litter (sow) to be managed throughout starter, grower, and finisher phases of production. Progeny will also be assessed for robustness (susceptibility to a pathogen challenge) along with gut health and development in the starter phase. Comprehensive carcass and meat quality evaluation will be conducted including loin and bacon quality assessments. Estimated nitrogen, phosphorus and carbon balance during gestation and lactation and margin over feed costs will also be determined to assess impacts on the environment and producer profitability. The ultimate goal of this work is to examine how sow management using ESF can impact lifetime sow productivity and retention in the herd, and carry over effects on to her progeny for growth performance and carcass and meat quality. Use of ESF for sow management has potential to improve animal welfare and returns for pig producers while producing better quality pork for consumers. **. **********************

将进行一项为期3年的研究，以检查长期收益，以密切满足妊娠期间和跨平等的各个母猪的养分需求，并在集团住房系统中进行管理，并使用计算机控制的电子SOW馈线（ESF）。该研究将全面评估SOW的生长和生殖性能，福利，行为和身体状况：1）通过在整个妊娠（控制）或2）中喂养传统的一相 - 相位喂养计划来管理母猪，每天调整饲料水平，而营养需求在整个诊断中会变化（精确的养分）。通过将0.2％的SID LYS和0.8％SID LYS饮食融合，基于目标的体重增加，将实现后者。母猪的性能，行为和体重增加将在整个泌乳过程中受到监测，并评估预性仔猪的性能。该项目旨在在研究开始时使用ESF使用ESF进行3个连续的均等。 SOW后代的性能将使用来自12个对照母猪的10个小猪和12个精密饲料母猪的垃圾进行评估。这些仔猪将根据单个垃圾（SOW）进行销售，以在整个起动器，种植者和整理阶段的生产阶段进行管理。后代还将评估稳健性（对病原体挑战的易感性），以及在起动阶段的肠道健康和发育。将进行全面的尸体和肉质评估，包括腰带和培根质量评估。妊娠期间估计的氮，磷和碳平衡也将确定饲料成本上的含量和边缘，以评估对环境和生产者盈利能力的影响。这项工作的最终目标是检查使用ESF的母猪管理如何影响终生的母猪生产力和在牛群中的保留率，并将其赋予她的后代，以获得成长性能，car体和肉质的质量。使用ESF进行母猪管理有可能改善动物福利和生产者的回报，同时为消费者生产更好的猪肉。 **。 **********************
