Genome-Wide Association Study of Piglet Uniformity and Farrowing Interval
Piglet uniformity (PU) and farrowing interval (FI) are important reproductive traits related to production and economic profits in the pig industry. However, the genetic architecture of the longitudinal trends of reproductive traits still remains elusive. Herein, we performed a genome-wide association study (GWAS) to detect potential genetic variation and candidate genes underlying the phenotyp...
متن کاملEffects of farrowing induction on suckling piglet performance
Materials and methods: The 122 sows in this study were allocated to two treatment groups or served as controls. Treatments consisted of two 1-mL (87.5-μg) injections of cloprostenol administered at a 6-hour interval on gestation day 114, either vulvomucosally (VM) or intra-abdominally (AB) into the external abdominal oblique muscle. Controls received two 1-mL injections of sterile saline admini...
متن کاملNebraska's Modified-Open-Front Farrowing Houses Design and Operation
T modified-open-front non-mechanically ventilated farrowing houses with creep boxes were operated over a two year period. Annual energy requirements were in the range of 10.6 to 10.9 cents per crate per day. No adverse effects on pig performance were realized. In most instances pig performance exceeded national standards of excellent performance—survival rates in excess of 90% and 21-day pig we...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولEffects of day of farrowing induction and spontaneous versus induced farrowing on sow and suckling piglet performance
Results: Analysis 1: Gestation length (mean ± standard error) was 114.01 ± 0.08, 114.67 ± 0.08, and 115.19 ± 0.09 days for day 113, 114, and 116 groups, respectively; spontaneous farrowing occurred in 6.50%, 14.89%, and 80.83% of sows. There was no treatment effect on number born alive (NBA), mummies, stillborns, litter weaning weight, litter average daily gain, percentage litters receiving med...
