Suckled Bos indicus  Bos taurus cows were used to compare a Select Synch/CIDR + timed artificial insemination (AI) protocol (SSC) vs a modified Co-Synch/CIDR protocol (COS). Five groups of suckled Bos indicus  Bos taurus cows were evaluated (n=659). Cows received GnRH and a CIDR on d 0. On d 7, SSC cows had their CIDR removed and received prostaglandin F2α (PGF2α), whereas COS cows had their ...

In this study, the effects of four different temperatures on sporulation and development 6 Bacillus species, 2 native 4 reference were investigated. The SDS PAGE analysis emerged that two proteins, 40 39 kilodalton (kDa), produced by sphaericus ATCC 2362 after 24 48, respectively hours at 48°C, local isolate 48 42°C 31 48°C. Additionally firmus (ATCC 14573) a kDa protein 52°C thuringiensis var....

Reproductive biotechnologies find application both in conservation of endangered species and to improve production from domestic animals. The cross between Mouflon and domestic sheep could be exploited to produce suckling lamb, a foodstuff with high organoleptic qualities and that could meet modern consumer demand. Mouflon semen was collected from two adult males using an artificial vagina duri...

BACKGROUND To investigate the association between long working hours and self-rated health (SRH), examining the roles of potential confounding and mediating factors, such as job characteristics. METHODS Data were pooled from seven waves (2005-2011) of the Korean Labour and Income Panel Study. A total of 1578 workers who consecutively participated in all seven study years were available for an...

There is large variation in dominant follicle diameter at the time of GnRH-induced ovulation in the CO-Synch protocol [a first GnRH injection on d -9 (GnRH1), followed by PGF(2alpha) on d -2, and a second GnRH injection (GnRH2) with timed AI on d 0], and the reason for the presence of small dominant follicles at GnRH2 is not known. Our hypothesis was that ovulatory response to GnRH1 and progest...

the present study was undertaken to examine the efficacy of a treatment regime using a controlled internal drug release (cidr) device in conjunction with injections of gonadotropin releasing hormone (gnrh) and prostaglandin f2α (pgf2α) on conception rate of repeat-breeding iraqi buffaloes. data were collected from 100 buffaloeswith repeat breeding in ninevehprovince housed at six private dairy ...

The objective of this study was to quantify fixed-time AI (TAI) pregnancy rates resulting from reduced intervals between 2 25 mg dinoprost tromethamine (PG) injections on d 5 of a 5-d CIDR-Co-synch estrus synchronization program. Angus and Angus-influenced commercial cows (n = 873) maintained on native pasture at 3 locations were randomly assigned to treatments, blocking for BCS and postpartum ...

This experiment was conducted to determine the reproductive performance of Kurdi ewes which were artificially inseminated (AI). In total 240 Kurdi ewes, weighing 49.5±2.5 kg were used in the trail. The ewes were allocated randomly to one of four groups (n=60/in each group). For synchronizing, controlled internal drug release (CIDR) was placed in the vagina of all individuals for 14 days. After ...
