Fixed-time artificial insemination in buffalo

open access: yesItalian Journal of Animal Science, 2010
Artificial insemination (AI) in buffalo has limited use worldwide due the difficulties in the estrus detection and in finding an adequate moment for this procedure. Therefore, an alternative to increase the number of buffalo that are inseminated is the use of protocols that allow the AI without the need of estrus detection, usually called fixed-time AI

Robust Weighted Timed Automata and Games [PDF]

open access: yes, 2013
Weighted timed automata extend timed automata with cost variables that can be used to model the evolution of various quantities. Although cost-optimal reachability is decidable (in polynomial space) on this model, it becomes undecidable on weighted ...

Robust Controller Synthesis in Timed Automata [PDF]

open access: yes, 2013
We consider the fundamental problem of Büchi acceptance in timed automata in a robust setting. The problem is formalised in terms of controller synthesis: timed automata are equipped with a parametrised game-based semantics that models the possible ...

Cervical timed artificial insemination in ewes

open access: yesAgrociencia Uruguay, 2017
The aim of this work was to generate information on protocols to synchronise estrous and ovulation using prostaglandin (PG), where the injections were administered at short (7 or 10 days), mid (12 or 13 days) or long intervals (14, 15 or 16 days). To assess its use for cervical timed artificial insemination (TAI) with fresh semen they were compared to ...

Artificial Insemination at Fixed Time in Bufalloes

open access: yes, 2011
To maintain a calving interval of 13-14 month in buffaloes, successful breeding must take place within 85-115 days (d) after calving. Complete uterine involution and resumption of ovarian activity and heat expression usually takes place around 20-50 d post partum (dpp); therefore, there is a window of 35-95 d to rebreed a cow and get her pregnant to ...

Profitability of a dairy sheep genetic improvement program using artificial insemination [PDF]

open access: yes, 2010
This simulation study investigated the farm-level economic benefits of a genetic improvement scheme using artificial insemination (AI) with fresh ram semen in dairy sheep of the Chios breed in Greece. Data were collected from 67 farms associated with the

Different times to perform timed artificial insemination when using a P4/E2/eCG-based protocol in buffalo [PDF]

open access: yesCiência Rural, 2020
: The aim of this study was to evaluate different times for timed artificial insemination (TAI) in buffalo submitted to a P4/E2/eCG-based protocol. In this study, 204 buffaloes were distributed into one of two groups (TAI56, n=103 and TAI64, n=101). At a
