Synchronization of estrus in swine
Production calendars for most swine farms are based upon the reproductive cycle of sows and gilts. The key reproductive event that determines when females begin their reproductive cycles is the onset of estrus. Estrus normally occurs spontaneously in gilts and mature females that are not pregnant or lactating. Once estrous cycles have begun, they normally occur every 18 to 21 days. From a produ...
متن کاملCurrent concepts in estrus synchronization in swine
Several managerial and pharmacological methods are available for porcine estrus synchronization. Before implementing a method, producers must have a clear idea of the goal of estrus synchronization and a realistic expectation of the outcome. Induction of precocious puberty in gilts is perhaps the most economically favored estrus synchronization technique available to swine producers. Appropriat...
متن کاملControl of red deer (Cervus elaphus) stag domination in rut season by estrus synchronization
BACKGROUND: Inbreeding is one of the major problems of small size herds of red deer in refuge wildlife parks. OBJECTIVES: The aim of the present study was to use estrus synchronization technique in red deer (Cervus elaphus) based on natural mating to control the dominancy and social rank of stags and inbreeding. METHODS: In this study, hinds (n=6) were captured and caged at breeding season (ear...

Background: Acute-phase proteins (APPs) may be increased due to different stresses during estrus phase in farm animals. Aims: Determining changes of APPs at different phases of non-synchronized estrous cycle group (NSEG), and Ovsynch-synchronized estrous cycle group (SEG) in Holstein cows. Methods: Twelve non-pregnant clinically and paraclinicaly healthy Holstein cows with a body condition scor...
