The new shape of bovine fertility
A revolutionary approach
to fertility
Developed by Ceva – Europe’s leading animal fertility experts
PRID Delta is the easiest,
most comfortable way to optimise cattle fertility.
Designed by our specialised R&D department
with effectiveness and animal comfort in mind,
PRID Delta is a revolutionary device, made
from a polyethylene spin and EVA (Ethyl Vinyl
Acetate), for faster and more consistent release
of progesterone. Once inserted, PRID Delta
provides a controlled release of 1.55g of natural
progesterone–effortlessly and comfortably for
improved results.

The new shape of bovine fertility
Unique new shape design
PRID DELTA has been developed with the objectives to
keep the efficacy of PRID spiral with an improved retention,
tolerance and ease of use.
The triangular shape allows PRID DELTA to distribute pressure more evenly
on the uterine tract with one of its sides completely leaning against the
vagina’s inner walls for both maximal contact surface and animal comfort.
Progesterone release over time by product
T-shape devices
PRID Delta surface area is a key element because it ensures
contact and exchange with vaginal environment. PRID
Delta surface is 155cm2 vs 120cm2 for a T-shape device.

Anticipating interval from calving to conception is highly beneficial to dairy
producers and the value of each day open varies approximately from 2 to 5€.
Both graphs shown below demonstrates the importance of not losing the handle on
days open in a dairy.

Each point increase in pregnancy rate is worth about 20€!

Dairy herds with shorter average days open (calving to conception interval) tend
to have lower average days in milk (Shown in the graph below, Souza et al., data to be
published in 2012) and greater average milk production, plus more replacement
heifers and faster genetic gains!

Beef herds getting more cows pregnant at beginning of the breeding season tend
to have more cows calving each year and greater average interval from calving to
initiation of breeding season = overall reproduction efficiency is improved, lessen
culls due to reproductive failure and more calves on the ground every year!
By helping heifers to become pregnant!
Heifers calving too old or with excessive body scores due to greater
age tend to have more metabolic problems, lower milk production, and lower fertility
postpartum (Ettema and Santos et al., 2004). Be proactive and get them pregnant
sooner!

PRID DELTA, Optimum fertility for
profitable reproduction
Key benefits:
Synchronisation of oestrous and ovulation
in cycling cattle
Induction and synchronisation of oestrous
in non cycling cattle
Synchronisation of heifers and cows to maximize production goals.
Synchronisation of batches of heifers and cows to allow artificial insemination
use and to improve results of the breeding season in consecutive years.
Allows effective resumption of cyclic ovarian activity in dairy cows with
different anoestrus conditions (presence of small follicles, large-follicle
anovular condition common in modern high producing cows, and follicular
cysts).
Insemination without oestrous detection to avoid failures due to bad oestrous
detection or poor oestrous expression.
Allows resumption of cyclic ovarian activity in case of suckling anoestrus, it
may represent up to 80% of beef cows in some management conditions!
Treatment of unsuccessful inseminated cows coming regularly in oestrous:
repeat breeding.
Reduces problems with abnormally short-cycles in dairy and beef herds.
Allows precise synchronisation of donors and recipients in embryo transfer
and in vitro Fertilisation (IVF) programs.
Synchronisation allows improved interval from insemination to ovulation as
compared to insemination after natural oestrous.
Allows reduction of calving-to-conception interval for maximal milk
production in dairy herds (lower average days in milk) and balanced breeding
season in beef herds (more cows pregnant before middle of breeding season).

How to use PRID DELTA
PRID DELTA
Optimum fertility for
profitable reproduction.
PRID DELTA is intended for single use only. It’s inserted through a unique
applicator, which must be cleaned and disinfected before and after use.
Inserting the applicator: Latex gloves are required at all times when
handling progesterone devices
Comfortable, safe and with a
controlled release
of progesterone
• Bend the device only once before inserting
in the applicator. Ensure the string is in the
appropriate slot.
• Lightly lubricate the distal end of the applicator
with an obstetrical lubricant.
• Clean the animal’s vulva before gently inserting
the applicator in the vagina.
• Once the applicator has reached the end of the
vagina, smoothly press on the handle to release
the device.
• Remove the applicator gently and ensure the
string is outside the vulva.
• Shorten the string according to the animal’s size
if necessary.
For oestrous synchronisation
and Fixed Time Insemination
Efficacious in cycling and non-cycling
mature cows and virgin heifers
At Removal:
• Remove the device by gently pulling on the
exposed string.
Withdrawal period: • Meat and offal: zero days
• Milk: zero days

RBPD1201
prid®delta 1.55g Vaginal delivery system for cattle COMpOSITION: progesterone 1,55 g per device. INDICATIONS: For the control of the œstrus cycle in cows and heifers
including: Synchronisation of œstrous in cycling cattle. To be used in combination with a prostaglandin (pGF2). Induction and synchronisation of œstrous in non cycling
cattle. To be used in combination with a prostaglandin and equine Chorionic Gonadotropin (eCG, in the past called pMSG). CONTRA-INDICATIONS: Do not use in sexually
immature heifers. Do not use before 35 days have passed since previous calving. Do not use in animals suffering from infectious or non-infectious disease of the genital
tract. Do not use in pregnant animals. See section Use during pregnancy and lactation. ADVERSE REACTIONS: During the course of the seven day treatment, the device may
induce a mild local reaction (i.e. inflammation of the vaginal wall). A clinical study carried out with 319 cows and heifers has demonstrated that 25% of animals presented
ropy or cloudy vulvar secretions at the device removal. This local reaction disappears rapidly without any treatment between removal and insemination and does not affect
fertility at inseminations nor pregnancy rates. If you notice any serious effects or other effects not mentioned in this leaflet, please inform your veterinary. DOSAGE, ROUTE
AND METHOD OF ADMINISTRATION: Vaginal use. 1.55 g of progesterone / animal for 7 days. Using an applicator, insert one device into the vagina of the animal. The
intravaginal device should stay in place for 7 days. In cycling cattle, the device has to be used in combination with a prostaglandin, injected 24 hours prior to removal of the
device. In non cycling cattle, an injection of a prostaglandin must be done 24 hours prior to removal of the device and an injection of eCG at the time of removal. The device
is intended for single use only. WITHDRAWAL pERIOD: Meat and offal: zero days. Milk zero days. During the treatment meat, offal and milk can be delivered for human
consumption CATEGORy: List II. pOMV. pRESENTATIONS: cardboard box containing 10 sachets of 1 device. polyethylene box containing 50 sachets of 1 device. Sachet
containing 10 devices. NAME AND ADDRESS OF THE MARKETING AUTHORISATION HOLDER: CEVA SANTE ANIMALE - 10 av. de la Ballastière - 33500 LIBOURNE.
