“…Effect of calving season on gestation length was insignificant. Nevertheless, our findings were numerically comparable with the studies of Mikláš et al (2019b) who in one dairy herd observed longest gestation lengths in winter and partialy also with the work of Tomasek et al (2017). Some authors explain thesse changes by variable temperatures at calvings, with shortest gestation lengts in summer (Wright et al, 2014).…”

“…Environment is considerably affecting dairy cows' production as well as reproduction. In this respect some authors reported role of calving season on the future milk production (Barash et al, 1996;Froidmont et al, 2013) as well as on gestation length (Tomasek et al, 2017). Numerous authors suggested that this seasonal effect on dairy cows' milk yield could be mediated via photoperiod (Dahl and Petitclerc, 2003;Rius and Dahl, 2006;Barash et al, 1996), and very importantly by changes in temperatures (Dahl et al, 2016), especialy during the dry period (Dahl and Petitclerc, 2003).…”

“…The impact of calving season, dams' parity on milk yield and gestation length of dairy cows as well as calves (Tao et al, 2019). Nevertheles, Tomasek et al (2017) indicated season of calving as more important factor affecting gestation length. Moreover, gestation length could be affected also by dams' parity (Tomasek et al, 2017), where younger cows had shorter gestation compared to older cows (Norman et al, 2009).…”

The purpose of the study was to asses the effect of calving season and dams' parity on milk yield and gestation length of dairy cows. We examined 93 animals of Slovak spotted breed from the farm located in western Slovakia (Lower Váh region), in years 2014-2017. The herds' average 305-d milk yield was 8,133 ±1,380 kg. The calving season was divided into four categories: spring (March to May), summer (June to August), autumn (September to November) and winter (December to February). The factor of dams parity was divided into 4 groups: 1 st parity cows, 2 nd-3 rd parity cows, 4 th and higher parity cows. Calving season affected significantly milk yield of dairy cows (P <0.01). The highest 305-d milk production was oberved in winter calvings (8,942 ±218 kg) and the lowest in spring calvings (7,377 ±287 kg). The gestation length was not signifficantly altered by calving season (P >0.32). Dams' parity was not significantly affected by 305-d milk yield (P >0.22). Nevertheless, the animals on the 4 th and higher lactation were numerically more productive (8,481 ±259 kg) compared to the dairy cows on their 1 st , 2 nd-3 rd lactation (8,123 ±264 kg; 7,884 ±223 kg; resp.). The dams' parity significantly affected gestation length (P <0.02), with the shortest gestation length in 1 st parity dams (278 ±2 days) and the longest gestation in 2 nd-3 rd parity dams (284 ±1 days).To sum up, our results suggest significant role of calving season in relation to milk yield and significant effect of dams' parity on gestation length.

“…The GL and factors affecting it have been investigated extensively in dairy cows and it was confirmed that different breeds have different GL (Silva et al, 1992;Johanson and Berger, 2003;Norman et al, 2009;Chud et al, 2014). There are a number of factors identified to impact GL such as genetics, month of conception (or calving), age and parity of the dam, calf gender, litter size (single vs. double), the number of days in milk, and the level of milk production (Silva et al, 1992;Nogalski and Piwczyński, 2012;Tomasek et al, 2017). Although the GL is not included in genetic evaluations in most countries, several studies have confirmed that genetic variation for GL is large enough to change it through selection (Chud et al, 2014;Silveira et al, 2015;Lacerda et al, 2018;Haile-Mariam and Pryce, 2019).…”

In this study, 252,798 lactations on 108,077 cows in 433 herds were used to determine the association between gestation length (GL) and lactation performance, lactation curve, calf birth weight and dystocia in Holstein dairy cows in Iran. The GL averaged 278.1 ± 5.41 d, was categorized as short (SGL; at 1 SD below the population mean), average (AGL; the population mean ± 1 SD), or long (LGL; at least 1 SD above the population mean). Factors including parity, calf gender and calving season were associated with the GL. Primiparous cows with SGL had less lactation performance than those with longer GL; however, there was no difference between those with AGL and LGL. Multiparous cows with longer GL always had more partial and 305-d lactation performance. Primiparous cows with SGL produced less milk at the beginning of lactation and at the peak than those with AGL or LGL; inverse trends were found for lactation persistency, upward and downward slopes of the lactation curve. Within multiparous, a direct relationship was found between GL and the peak yield, where cows with longer GL always produced more milk at the peak. Multiparous cows with SGL produced less milk at the beginning of lactation, reached their peaks later, had higher lactation persistency and showed a lower upward slope of lactation curve than those with AGL orLGL. There was a direct relationship between GL and calf birth weight, where cows with longer GL had calves with more weight at the birth. Within primiparous, cows with SGL had the lowest and those with LGL had the highest rate of dystocia. However, multiparous cows with AGL had a lower rate of dystocia than those with SGL or LGL. Although there was a direct relationship between GL and lactation performance, intermediate GL seems optimal when considering dystocia.

“…Sementara untuk mengatasi kematian perinatal dapat dilakukan dengan menambah gonadotrophinreleasing hormone (GnRH) pada hari ke-28 hingga 41 setelah implantasi. Tomasek et al (2017) melakukan analisis kelahiran dan produksi susu sapi FH di Republik Czech dalam periode 20092014 dan menyatakan kejadian kembar dua terdapat dua kali lipat lebih banyak pada kelompok induk dengan produksi susu lebih tinggi dibandingkan dengan kelompok induk dengan produksi susu rendah. Namun belum diketahui hubungan antara peningkatan produksi susu dengan kejadian kembar dua.…”

The evidence of cattle with twinning birth is reported over the world, as well as in Indonesia, with the frequency in dairy cattle is a bit higher compared to beef cattle (4ƒ{10% : 1%). The heritability of twinning cattle is considered to be low, so does for the repeatability. This paper outlines the inheritance of twin born cattle, its geographic distribution and utilization for population accelaration as well as its contribution for meat supply. In Indonesia, twin born cattles are reported in 11 provinces and occured in Ongole crossbred (PO), Bali, Angus, Aceh, SimmentalxPO crossbred, LimousinexPO crossbred and FH breeds. The occurence of cattle with twinning birth in dairy and beef cattle is around 27.250 and 165.990 heads, with estimation 13.625 and 82.995 heads of dairy and beef cows, respectively. The optimistic scenario is expected to deliver 19.735 and 71.406 heads of dairy and beef calves every year, whereas pesimistic scenario resulting the birth of dairy and beef calves of 10.306 and 50.875 heads, respectively. These scenarios contribute to 2,6% and 1,8% of national calves born (3.500.000 heads every year) for optimistic and pesimistic scenarios, respectively, indicating that twinning genes in cattle do not significantly contribute to the addition of calves born in Indonesia. Several efforts to maintain the the population of twin born cattle can be conducted through option such as a) to maintain the twin born cattle population to the institution belongs to government or private; b) to allow farmers to raise the twin born cattle and c) to empower local farmers association as a networking who raise the twin born cattle. Eventhough the twin born calves contribution is low for national calves born, however, it is suggested to keep the genetic values for further requirement in the future, to provide technologies for early identification or moleculer of twinning cattle carriers as well as to explore the genetic potential for further development. In the future, development of the twinning cattle can be conducted through frozen sperm distribution for artificial insemination.Keywords: Beef cattle, dairy cattle, gene for twinning, heritability AbstrakSapi dengan potensi beranak kembar memiliki frekuensi kelahiran lebih tinggi pada sapi perah (410%) dibanding sapi potong (1%). Laju pewarisan (heritabilitas) sifat kelahiran kembar sangat rendah, demikian pula dengan laju pengulangan (ripitabilitas). Tulisan ini membahas sifat pewarisan gen sapi beranak kembar di Indonesia, distribusi sapi dengan potensi gen kelahiran kembar, peluang pemanfaatannya bagi peningkatan populasi dan penyediaan daging sapi. Di Indonesia, kelahiran kembar sapi terdapat di 11 provinsi dan terjadi pada rumpun sapi PO, Aceh, Bali, FH, persilangan Aberden Angus, persilangan Simmental x PO, persilangan Limousine x PO. Gen beranak kembar sapi perah dan sapi potong berturut turut diperkirakan sekitar 27.250 ekor dan 165.990 ekor, dimana populasi sapi betina sekitar 13.625 dan 82.995 ekor untuk sapi perah dan sapi potong. Skenario optimis pemanfaatan gen sapi kembar , diharapkan dapat memberikan angka kelahiran sebanyak 19.735 dan 71.406 ekor, berturut-turut untuk sapi perah dan sapi potong. Sementara skenario pesimis menghasilkan kelahiran anak sapi perah dan sapi potong, berturut-turut sejumlah 10.306 dan 50.875 ekor. Kedua skenario tersebut menyumbang 2,6% (optimis) dan 1,8 % (pesimis) dari total kelahiran per tahun (3.500.000 ekor). Keberadaan sapi beranak kembar di Indonesia belum memberikan sumbangan nyata bagi peningkatan populasi, akan tetapi perlu dipertahankan keberadaannya. Berbagai usulan yang dapat dilakukan untuk mempertahankan populasinya antara lain: a) pengumpulan di satu tempat, baik milik pemerintah atau swasta yang tertarik memelihara dan melakukan pengamatan dengan biaya yang sangat mahal; b) pemeliharaan sapi kembar diserahkan kepada peternak dengan konsekuensi sewaktu waktu akan punah karena keterbatasan kemampuan membiayai pemeliharaan, c) membentuk kelompok peternak pemelihara sapi kembar sebagai sarana pertukaran informasi. Namun demikian, eksplorasi sifat genetik perlu terus dilakukan baik secara konvensional maupun secara molekuler, sementara pengembangan sapi kembar dapat dilakukan melalui pembuatan semen beku yang diimplementasikan dengan teknologi inseminasi buatan.Kata Kunci: Sapi potong, sapi perah, gen beranak kembar, heritability.
