The present study was conducted to evaluate the role of age in effectiveness intravaginal progestin-impregnated sponges (IPIS) along with equine chorionic gonadotropin (eCG) on multiple birth rates Awassi ewes. One hundred mature ewes (live weight 35–40 kg and 2–5 years) were allocated three groups according their ages (n = 29, 2-3 years;n 34, 3-4 years; n 37, 4-5 years). All impregnated IPIS, ...

Reproductive performance was evaluated in non-lactating crossbred ewes to which were administered the exogenous GnRH and PMSG. The ewes were randomly allocated in three treatment groups (n=40).After accurate detection of estrus and 2 hours prior to mating, 2.5 mL of distilled water and 2.5 mL of GnRH were injected intramuscular to each ewe of the first (control) and second group, respectively. ...

this study was conducted to detect polymorphism of gene bmp15, a member of transforming growthfactor β (tgfβ) family which has a crucial role in controlling the ovarian follicles development,ovulation rate and fertility. samples were randomly selected from 91 najdi goats in 3 geographicallocations, northwest, southeast and center of khuzestan province. after dna extraction, amplification of235 ...

Abstract The management of sheep reproduction requires the induction and synchronization estrus cycle ovulation for ewe out-of-season and/or synchronized lambing. These managements are based on insertion an intravaginal device controlled internal drug release (CIDR or sponge) then administration a hormonal injection, such as PMSG, eCG, hCG, GnRH. This study aimed to compare impact CIDR sponges,...

As Computer Supported Collaborative Learning (CSCL) gains a broader usage in multiple educational scenarios facilitated by the use of technology, the need for automated tools capable of detecting and stimulating collaboration increases. We propose a computational model using ReaderBench that assesses collaboration from a dialogical perspective. Accordingly, collaboration emerges from the inter-...

New Zealand Journal of Ecology (1998) 22(1): 71-85 ©New Zealand Ecological Society Availability of suitably-sized support is a major factor limiting liane access to the canopy because lianes are not self-supporting (Putz and Holbrook, 1991). In the Knysna Forest, South Africa, aspects of forest architecture which affect support availability, rather than abiotic factors such as light levels and ...

I SIIOULD have mentioned at the outset of my attempting to give the medicinal properties of Indian drugs that have come under my notice and experience, that it should be understood, though a good many articles on Materia Medica have been written from time to time by others, yet there may be some therapeutical actions of those drugs which have not been touched 011 by them, I avail myself of the ...

A total of 1243 records of 585 dairy Friesian cows collected through 8 years (1997-2004) were used to study factors affecting retention of placenta and its influence on reproductive performance and milk production. The obtained results showed that the percentage of retained placenta averaged 24.90%, the highest percentage was in the year 1998 (46.3%) and it increased significantly (P<0.05) with...
