Sow feed intake and lifetime reproductive performance
For many breeding companies, performance testing in maternal lines is generally confined to traits such as average daily gain (ADG), back fat (BF) and perhaps loin muscle depth or area (LMD or LMA), along with litter size traits such as number born alive (NBA) or total born (TB). More sophisticated breeding programs will also accommodate traits associated with sow performance, longevity or pigl...
متن کاملPhysiology and Endocrinology: Reproductive Endocrinology
The aim of the present study was to investigate the endocrinology of periestrus period and the days after until estrus in ewes (n = 40) synchronized out of breeding season and diagnosing the related pregnancies after laparoscopic insemination comparing to different doses of PMSG that was used. Animals treated for 12 d with CIDR followed by administration with different doses (0, 450, 550, 650, ...
متن کاملREPRODUCTIVE ENDOCRINOLOGY AND INFERTILITY Male reproductive proteins and reproductive outcomes
An enormous diversity of antigenically distinct proteins is found in seminal plasma. These include proteases, protease inhibitors, signal transduction molecules, protein kinases and phosphatases, transporter proteins, structural molecules, and immune response proteins. Sperm, too, carry a plethora of surface proteins; these mediate species-specific binding to the zona pellucida surrounding the ...
متن کاملType of accommodation during gestation affects growth performance and reproductive characteristics of gilt offspring.
The objective was to determine effects of the type of gestation accommodation to which dams were exposed on growth performance and age at puberty in gilt offspring. Yorkshire x Landrace gilts (n = 81; 26.9 +/- 0.8 kg of BW) were placed in pens of 3 gilts each. Each pen contained gilts farrowed exclusively by gilts exposed to 1 of 3 gestation accommodations: 1) individual crates throughout gesta...
متن کاملReproductive Biology and Endocrinology
Objective: To study pathophysiologic pathways in spontaneous preterm birth and possibly the racial disparity associating with maternal and fetal genetic variations, using bioinformatics tools. Methods: A large scale candidate gene association study was performed on 1442 SNPs in 130 genes in a case (preterm birth < 36 weeks) control study (term birth > 37 weeks). Both maternal and fetal DNA from...
