“…After it is identified as the luteolytic agent, its commercialization follows with natural and synthetic forms to shorten the luteal phase, which makes it economically feasible for synchronizing estrus (Cordova-Izquierdo et al, 2009;Diaz et al, 2005;Ginther et al, 2010;Paul et al, 2015Paul et al, , 2015Sprott & Carpenter, 2007) and M. C. Lucy et al (2004). It will operate in single and double injection systems alone or combination with other hormones.…”

“…According to Sprott and Carpenter (2007) and Paul et al (2015)'s report, in cyclic females estrus occurs within 3 to 8 days after they are given intramuscular injections of PGF2α (Lutalyse ® ) or one of its analogs (ProstaMate ® , Estrumate ® , estroPLAN ® , In-Synch ® ) depending on the day of injection and the presence of dominant follicles. It only acts during the luteal phase of the cycle (Sprott & Carpenter, 2007).…”

“…According to the reports of Gupta et al (2008), Cirit et al (2008), Sveberg et al (2011), Roelofs and Kooij (2015), and Paul et al (2015) heat detection is a major limiting factor and the base for success. Failure of estrus detection results in infertility in cattle (Gatius et al, 2005;Cirit et al, 2008;Girmay et al, 2015, Fact Sheet IRM-2;Paul et al, 2015). Generally strict follow up, the use of heat-detector devices and technologies helps to increase detection ability to have successful breeding (Cirit et al, 2008;Jemal et al, 2016).…”

Reproductive cyclicity provides cattle with repeated opportunities to become pregnant. Understanding the physiology and endocrinology of the estrus cycle gives a great opportunity for reproductive management and control of the estrus cycle. To manage and control the cycle, there are lot of assisted reproductive technologies, of them estrus synchronization with prostaglandins (PGF2α) is the one. PGF2α is known to have the ability to regress the corpus luteum (CL). The success of the synchronization program is limited by numerous intrinsic and extrinsic factors like proper levels of nutrition, body condition, health, good estrus detection technique, semen quality, proper time of insemination, and efficiency of AI technicians. However, inadequacy in any of these areas can spell disaster for an estrus synchronization program. The choice of a protocol which fits the specific situation under consideration is the base for the success of any prostaglandin-based estrus synchronization programs. As a conclusion, the choice of technically right and practically feasible protocol is essential for a successful breeding program.

“…Sinkronisasi estrus pada kerbau perlu dilakukan dalam program IB, mengingat tanda-tanda estrus pada kerbau umumnya tidak jelas terlihat sehingga sulit untuk mendeteksi estrus, dengan intensitas dan durasi estrus yang rendah dan terjadi pada malam hari (Barile 2012). Sinkronisasi pada dasarnya dilakukan dengan menggunakan hormon prostaglandin atau progesteron, yang keduanya bertujuan memperpendek atau memperpanjang fase luteal yang menyebabkan penurunan progesteron pada level terendah, sehingga memungkinkan terjadinya peningkatan hormon estrogen dan luteneizing hormone (LH) (Paul et al 2015). Sinkronisasi estrus hormonal menginduksi berahi yang dapat meningkatkan kesuburan dan memperpendek jarak beranak (Kalwar et al 2015).…”

Buff and dairy buffaloes have an important role in farming system to produce meat, milk, and fertilizer. Their productivity and population have been decreasing due to several reasons such as inbreeding depression and lack of sires. This paper presents alternative efforts to improve genetics of buffaloes through outbreeding fascilitated by artificial insemination (AI) and estrus synchronization to decrease inbreeding rates. Effort to reduce inbreeding depression is conducted by introducing new buffalo genes from distant populations known as outbreeding. Indonesian Research Institute for Animal Production has initiated an outbreeding program in buffalo through AI. The pregnancy rate varies between 40-80% using estrus synchronization with prostaglandin and fixed time AI. Outbred offsprings have higher growth performance and selling price than offsprings of natural breeding. The outbreeding program through AI in buffaloes need to be carried out sustainability to increase availability of qualified breeding stocks.

“…The productive traits of farmed breeds of dairy cattle are largely determined by their genotype. In this regard, in recent years, much attention has been paid to the study of biological characteristics and the identification of adaptation processes that affect the realization of the genetic potential of cows, to organize further breeding with imported livestock and their offspring [9,10,11].…”

This work aims to identify the level of productivity of Holstein cows of different breedings. The experimental studies were performed using purebred Holstein animals imported from Germany, Hungary, and Finland. When studying the exterior-constitutional features of livestock raised on the farm, it was found that Holstein cows as a whole were characterized by a relatively strong constitution, a proportionally developed and slightly elongated body with average live weight, deep chests with well-defined milk veins, glandular and properly attached bath-like and cup-shaped udder, with an average intensity of milk yield (2.12-2.4 kg/min). According to the expressiveness of dairy forms, the best indicators were for animals of Hungarian breeding with the linear affiliation of Reflection Sovering, and in cows of German and Finnish breedings - Montwik Chieftain. A study of the dairy productivity of cows showed that the greatest milk yield over 305 days for three lactations, depending on the linear affiliation, was for Hungarian cows: during the 1st lactation - 6465.9- 6951.2 kg, the 2nd lactation - 7463.5-7706.2 kg, according to the 3rd lactation - 8254.2-8297.7 kg of milk. A comparative evaluation of the dairy production of cows showed that the highest dairy productivity was noted in cows of the Reflection Sovering line. Thus, the average milk yield in cows of this line in the first three lactations was higher than in analogs of the Finnish breeding by 885 kg (13.02%) and German one - by 892 kg or 13.1% (P<0.05), Vis Beck Ideal by 444.5 kg (6.2%) and 807 kg or 12.0% (P<0.01) respectively. The animals of the Montwik Chieftain line of the Hungarian breeding exceeded in the milk yield of the German cows by 176.5 kg (2.4%) and the Finnish cows by 238.2 kg or 3.3%. Indicators of the coefficient of variation in milk yield show that the herd of Holstein cows in the first and third lactations is very heterogeneous. According to the second lactation, the representatives of the Vis Beck Ideal line of the German selection and the Montwik. It was established that in the coefficient of consistency of lactation, cows of German breeding exceeded the analogs of the Finnish and Hungarian breedings by 4.7 and 6.7%, respectively. Herewith, in the Hungarian cows, the lactation full value indicator was higher by 18.3% and 1%, which indicates higher stability of milk yield of cows of this group for the entire lactation. In such a way, our analysis of the morphofunctional properties of the udder showed that the investigated groups of animals correspond to the technological requirements for industrial keeping technology and organizing machine milking.
