“…Similarly, calving season and year of calving also had a highly significant effect on Cal-Con. In sum, these findings could be due to seasonal variations in ambient temperature and feed availability, which in turn have recognizable influence on the reproductive physiology of cows (Kornmatitsuk et al 2008). Although the study farm was exclusively stallfeeding with supplementation of concentrates and mineral licks, the finding of prolonged Cal-Con may have been the product of combination of herd management and climatic conditions which in turn could influence the feeding of animals.…”

“…Numerous genetic and environmental factors are known to affect reproductive performance of dairy cows (Dobson et al 2007). Although the temperate dairy cattle have demonstrated their optimum performance in suitable climatic and production conditions, achieving the desired level of reproductive performance under the warm climate in tropical conditions is faced with several problems (Kornmatitsuk et al 2008;Avendaño-Reyes et al 2010). More focused and known management factors such as estrus detection, timing of insemination, use of proper semen handling and insemination, quality and fertility of semen and breeding bulls, and the skills in early pregnancy diagnosis have been reported to affect the reproductive performance of dairy cows (Farin and Slenning 2001).…”

A retrospective study was carried out to evaluate the reproductive performance of Holstein-Friesian cattle in Alage Dairy Farm in the Rift Valley of Ethiopia using data recorded from July 1983 to June 2005. Data of cows with complete information were considered, and a total of 1,104 records for calving to conception (Cal-Con), calving interval (CI), and number of services per conception (NSC), and 721 records for age at first service (AFS) and at first calving (AFC) were analyzed. The overall means (± S.E.) of AFS, AFC, Cal-Con and CI, and NSC were 991.4 ± 24.3, 1,265 ± 24.3, 285.8 ± 18.9, 561.3 ± 18.9 days and 1.69 ± 0.1, respectively. Parity significantly influenced NSC, Cal-Con, and CI. Season and year showed a significant effect on all the parameters, indicating the role of the environment and more specifically the influence of nutritional conditions at least for the long AFS and AFC, management practices, and climate on reproductive performance of the study herd. A more focused study to discern the elements of the reproductive constraints have been recommended.

“…This was probably caused by heat stress due to the different periods of hot humid weather, resulting in a longer DIM at first AI for the herds in Yamaguchi Prefecture. Cows suffering from heat stress had lower oocyte quality [28,29]; reduced duration and intensity of estrus, altered follicular development and impaired embryonic development [30]; and a higher incidence of abnormal resumption of postpartum ovarian cycles, lower heat detection rate, lower first AI conception rate and lower pregnancy rate [31]. Different housing systems contributed to the initiation of service in postpartum dairy cows.…”

Abstract. The aim of the present study was to show the distribution of cows by days in milk (DIM) at first AI, effect of DIM at first AI on reproductive performance and some factors influencing DIM at first AI. A total of 767 Holstein Frisian cows that calved from January 2004 to December 2007 in 14 dairy herds were used. The first AI conception rate (FAICR) was 34.0%. Seventy-five percent of the cows were first inseminated within 100 days after calving. FAICR increased linearly up to 100 DIM. A one unit (20 days) longer DIM at first AI within the first 100 days postpartum increased the likelihood of a 2.4% FAICR. However, cows first inseminated at an earlier stage of lactation showed better reproductive performance in terms of pregnancy rate and calving to conception interval than cows first inseminated at a later stage. A one day increase in the interval from calving to first AI reduced the likelihood of 0.85 days to become pregnant. Herd or region located in southwestern Japan, tie-stall herd, first AI in spring, higher parity, uterine infection, metabolic diseases and/or mastitis and abnormal resumption of postpartum ovarian cycles contributed to delaying first AI. Key words: Dairy cows, DIM at first AI, Reproductive performance (J. Reprod. Dev. 57: [643][644][645][646][647][648][649] 2011) ecreased conception rate at first AI in dairy cows has been reported worldwide [1][2][3][4], resulting in an increased number of services per conception, delayed conception and increase of days open. Our recent study also described that approximately 14% of 613 dairy cows in nine dairy herds in Japan had repeat breeding and that the repeat breeders showed extremely poor reproductive performance [5]. Nutritional interactions with reproductive performance in the early postpartum period through high feed consumption required to meet energy requirements have been recognized as reducing the first AI conception rate [6]. Changes in reproductive physiology due to elevated steroid metabolism [7] and metabolic changes in follicular fluid of the dominant follicle in early lactation [8] have been reported to be potential causes of reduction of the first AI conception rate in lactating dairy cows.Esslemont and Kossaibati [9] have provided a fertility management assessment checklist. To be considered good fertility management, 95% of the cows in the herd after calving must be serviced by keeping the average calving to first service interval at less than 70 days, the overall heat detection must be more than 55% and the pregnancy rate must be 50% or more. The requirements to achieve this target or high reproductive efficiency in a dairy herd are a disease-free transition period, high rates of submission to AI and a high conception rate per service [2]. However, many current dairy herds have difficulty breeding and achieving a high first AI conception rate in an optimum time.Conception rate has been reported to be higher in the later stages of lactation than in the early stages of lactation [3,[10][11][12]. Likewise, following an Ovsy...

“…This was probably caused by heat stress due to the hot humid weather in tropical condition, resulting in lower first AI conception rate and longer calving to conception interval. Cows suffering from heat stress had a lower oocyte quality (Sartori et al, 2002;Leroy et al, 2008), reduced duration and intensity of estrus, altered follicular development, and impaired embryonic development (Jordan, 2003), higher incidence of abnormal resumption of postpartum ovarian cycles, lower heat detection rate, lower first AI conception rate, and lower pregnancy rate (Kornmatitsuk et al, 2008). Therefore, in future, prevention of reproductive disorders such as repeat breeding will be required for both reproductive efficiency and animal welfare (Nakada, 2006).…”

ABSTRAKPenelitian ini bertujuan untuk mempelajari tingkat kejadian kawin berulang pada ternak sapi perah di daerah tropis. Penelitian ini merupakan studi awal yang dilaksanakan di Kabupaten Sinjai, Indonesia. Sebanyak 82 ekor ternak sapi perah pada lima kelompok tani/ternak digunakan dalam penelitian ini. Sebanyak 75,6% dari 82 ternak sapi perah mengalami kebuntingan setelah beberapa kali dilakukan inseminasi buatan (IB). Tingkat kejadian kawin berulang pada daerah ini sangat tinggi (62%). IB pertama setelah melahirkan, angka konsepsi pada IB pertama, dan jarak antara melahirkan dan kembali bunting adalah 62,5±15,2 hari, 0%, dan 202,8±150,0 hari. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan yang nyata antara ternak yang kawin berulang dan yang normal terhadap IB pertama setelah melahirkan (60,4±15,2 hari vs 68,3±28,6 hari). Namun demikian, ternak sapi perah dengan fertilitas normal hanya membutuhkan 123,3±52,9 hari untuk kembali bunting dan 2,4±0,8 kali inseminasi per kebuntingan, sedangkan ternak kawin berulang membutuhkan lebih banyak waktu (222,9±134,1 hari) untuk kembali bunting dan inseminasi per kebuntingan (4,8±0,9 kali). Sebagai kesimpulan adalah bahwa penampilan reproduksi ternak kawin berulang sangat rendah sehingga menurunkan penampilan reproduksi ternak secara keseluruhan.

This was a preliminary study conducted in Sinjai Regency, Indonesia. A total of 82 Holstein Friesian lactating cows from five dairy farmer groups were used in the present study. Of the 82 cows, 75.6% eventually became pregnant after repeated inseminations (AI). The incidence of repeat breeding in this area was very high (62%). Days in milk (DIM) at first AI, first AI conception rate, and calving to conception interval were 62.5±19.3 days, 0%, and 202.8±150.0 days, respectively. There was no difference in DIM at first AI between repeat breeders and normal fertility cows (60.4±15.2 days vs 68.3±28.6 days). However, normal fertility cows required only 123.3±52.9 days to conceive and 2.4±0.8 inseminations per pregnancy, whereas repeat breeders required significantly more days to conceive (222.9±134.1 days) and more inseminations per pregnancy (4.8±0.9). In conclusion, repeat breeder dairy cows under tropical condition had very poor and reduced reproductive performance.
