Approaches to increase reproductive efficiency in artificially inseminated dairy cows
Infertility has been linked to numerous factors in high producing dairy cattle in the last decades. The detection of estrus continues to present difficulties and, although progress has been made in regards to estrus synchronization and artificial insemination, the reproductive performance of dairy cows has not improved substantially. Moreover, in warm countries, summer heat stress is a major fa...
متن کاملEffect of number of motile sperms inseminated on reproductive performance of rabbit does.
The relationship between the number of motile sperms inseminated and fertility rate and litter size at birth in rabbits was investigated. A total of 651 artificial inseminations on multiparous rabbit does in different physiological states (lactating or not; sexually receptive or not) were inseminated with a number of motile cells/dose varying from about 1-20 x 10(6). The statistical model compu...
متن کاملEffects of PMSG Doses on Reproductive Performance of Kurdi Ewes Artificially Inseminated during Breeding Season
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 ...
متن کاملEffects of lactation on fetal survival and development in rabbit does mated shortly after parturition.
Primiparous rabbit does were mated within 12 h after parturition (d 0). They were immediately weaned (Group W; n = 31) or allowed to suckle 10 young rabbits (Group L; n = 32). Blood samples were collected at d 0, 7, 17, and 28. Feed intake and live weight were measured weekly and pregnant does (Group W, n = 24; Group L = 25) were slaughtered at d 28. Feed intake was 78% higher in L than in W fe...
متن کاملA naturally occurring human RPA subunit homolog does not support DNA replication or cell-cycle progression
Replication Protein A (RPA) is a single-stranded DNA-binding protein essential for DNA replication, repair, recombination and cell-cycle regulation. A human homolog of the RPA2 subunit, called RPA4, was previously identified and shown to be expressed in colon mucosal and placental cells; however, the function of RPA4 was not determined. To examine the function of RPA4 in human cells, we carried...
