“…This caused the low quality of embryos and untransferable embryo production. This result supported by [45] that a decrease in the count of transferable embryos in the inbreeding group Fx= 3 %-5.9%. The effect of inbreeding depression on ovarian activity in super ovulated cows.…”

“…The number of follicles of diameter 5 mm or less was negatively correlated with the number of follicles of diameter 6 mm or greater through the treatment period (r=-0.70,P<0.001 in the control group and r= -0.76, P<0.001). [43]. The number of large follicles at ovulations and CL occurred with lengthened protocol (7-day) than with the convention 4-day FSH treatment [32].…”

The objective of this research was to evaluate the effect of FTAI on embryo production that used GnRH plus progesterone combination to synchronize ovulation of 3 different parity of donor from local pesisir cows in west Sumatra. This study used timed embryo transfer program using GnRH plus progesterone combination in 3 local pesisir cows and 2 cows in time embryo program using estradiol plus progesterone of donor. Ovarian ultrasonography was performed on d 0 (time of AI) and at flushing to determine ovulatory diameter and ovulation. On d 0 at the time CIDR implant + PGF2α injection and on d 7 started ovsynch protocol administrated by injection GnRH and FSH for FTAI without detection estrus. The number and the quality of embryo was evaluated to determine the fertility of pesisir selatan cows. The result showed that the expression of estrus cows tend to high ovulation rate. The diameter size of a follicle was range from 5 to 15 mm with 10.67±2.96 mm in GnRH plus progesterone and 5 to 14 mm with mean was 8.75±2.05 mm in estradiol plus progesterone (P<0.005). The number of follicle ovulation was 27 in treatment A and 18 in treatment B (P<0.05). The number of CL and embryos was higher in treatment A. CL was 19, with 18 embryos and in treatment B was 9 with 6 embryos. The quality of embryo range from 1-4 grade with the transferable embryos was higher in treatment A than treatment B (P<0.05). There was the linear regression between ovular follicle, CL and number of embryos recovery of local pesisir cows. It was concluded that equal numbers of embryos and transferable embryo by using GnRH plus progesterone combination of local pesisir cows.

“…A number of factors influence the reproductive performance and conception rate in cattle (12), such as genetics (3), parity of lactation (13), NEB (14), and others. The fundamental reason for reduced fertility can be seen in the likely additive effect of the combination of various physiological and management factors (15).…”

The aim of this study was to evaluate the relationships between milk fatty acid group contents and subsequent reproductive performance in Holstein cows. A total of 27 cows in the 1st to 4th lactations were included in the evaluation. Cows were divided into primiparous and multiparous groups. Daily milk yields increased in the first 8 weeks of lactation. Body condition score decreased until the third month of lactation. As the cows gradually recovered from the negative energy balance, the contents of saturated fatty acids (SFAs) increased, whereas the contents of monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) decreased. The contents of SFAs and MUFAs were significantly (P < 0.01-0.05) correlated (r = -0.279 to r = 0.275) with all the reproductive traits evaluated (calving to first insemination interval, days open, and insemination index). PUFA was only correlated (P < 0.01) with calving to first insemination interval (r = -0.141). High milk SFA contents were associated with improved values of days open and insemination index, whereas opposite tendencies were observed for MUFA. It was concluded that the relationship was confirmed between the changes of different milk fatty acid group contents in early lactation, used as negative energy balance indicators, and subsequent reproduction results.

“…Both traits are related to individual genetics (Bezdíček et al 2007). However, deteriorating reproduction in recent years is also associated with the level of inbreeding (Bezdíček et al 2008;Bezdíček et al 2014) and the quality of the environment has an important impact, too. Good reproduction in dairy cows is associated with a period of sharp increase in milk production in early lactation, connected to increased demands on the metabolism of the whole organism (Stádník et al 2015) in maintaining the physiological condition of the cow (Stádník et al 2002) and allowing utilization of energy resources to provide the necessary endocrine indicators (Royal et al 2000;Beran et al 2013).…”

The aim of this study was to evaluate superovulation response in cows at various postpartum periods (early postpartum period up to 3.5 months; middle postpartum period 3.7-7 months; later postpartum period above 7.5 months after calving). The data included observation of 55 Holstein cows superovulated at one farm in the Czech Republic during the years 2010 and 2013. Reproduction traits (dependent variable) were represented as number of the corpora lutea, number of transferable embryos, morulae, blastocysts, total number of embryos and embryo recovery. For statistical evaluation we used the PROC GLM of SAS ® with fixed effect -breeding value of milk production. The study results show significant differences (P < 0.05-0.01) in the three postpartum periods (early, middle, and later postpartum periods) and the number of corpora lutea (4.6; 7.4; 10.8), number of total embryos (3.2; 2.9; 6.5) and transferable embryos (1.8; 1.7; 4.4). Effective timing of embryo transfer in the later postpartum period resulted in greater ovarian activity and embryo yield compared to early lactation periods.
