AB  - Main goal of each livestock production is profit. On dairy cow farms aim is to produce as much milk as possible, similarly on beef farms main aim is to produce as much meat as possible. Both productions (dairy and beef) are directly dependant on fertility since if there is no calf there is no milk or meat either. Cow fertility is influenced by numerous genetic and paragenetic factors. It is thought that nutrition and proper reproduction management can affect fertility up to 70%. Goal of our work was to compare four different productive systems and point out on problems that occurred, possible mistakes and solutions. On the basis of conducted research in Appling of protocols in feeding, control of health and reproduction of dairy cows in a period of three years we have concluded that adequate and monitored nutrition is a key for successful reproduction. Beside that it is necessary to constantly monitor of health and reproduction and to conduct therapeutic protocols in order to achieve herd fertility of 80%.
AB  - Cilj svake stočarske proizvodnje je profit. Na farmama visoko-mlečnih krava cilj je što veća proizvodnja mleka, sličan je slučaj i na farmama za tov, ali sa krajnjim ciljem proizvodnje što veće količine mesa. I jedna i druga proizvodnja direktno zavise od plodnosti jer bez teleta nema ni mleka ni mesa. Na plodnost krava utiču brojni genetski i paragenetski faktori. Smatra se da ishrana i pravilan menadžment reprodukcije mogu uticati na plodnost i do 70%. Cilj našeg rada je bio da prikažemo 4 različita proizvodna sistema krava i ukažemo na probleme, moguće propuste i njihova rešenja. Na osnovu sprovedenih ispitivanja u primeni protokola ishrane, kontrole zdravlja, proizvodnje i reprodukcije mlečnih krava, u trogodišnjem periodu, zaključili smo da je adekvatna i konstantno kontrolisana ishrana ključ za uspešnu reprodukciju. Uz to je neophodno konstantno praćenje zdravlja i reprodukcije i primena terapijskih protokola. Samo sinhronizovanim praćenjem ishrane i protokola zdravlja i reprodukcije može se postići plodnost krava preko 80% na godišnjem nivou.

AB  - Success in diary industry depends upon good management practices in all stages of production. Profitable milks production demands good nutrition, health, and optimal cow reproduction. Adequate feeding is base point for milk cow in ingesting sufficient amounts of feed dry matter (DM) which is a key factor in providing good body condition and high milk yield. Satisfactory ingestion of DM in transition period enables cows to be as shorter as possible in negative energy balance after calving. Most critical period for cows is a week before and week after calving. If negative energy balance is shorter, milk yield and fertility will be improved. In dairy cows it is important to prevent metabolic disorders caused by inadequate nutrition since they can have negative repercussions on production and fertility. By monitoring of cow body condition score in dry period, puerperal infective and metabolic diseases up to 42nd day after calving infertility can be significantly reduced. Heat detection, early pregnancy diagnosis by use of milk progesterone test and ultrasound enables achieving of fertility of 85% which is deemed optimal. In this paper review of certain procedures used in achieving optimal fertility in dairy cattle is given.
AB  - Uspeh u govedarstvu i proizvodnji mleka podrazumeva dobar menadžment svih faza u proizvodnji. Za profitabilnu proizvodnju mleka neophodna je dobra ishrana, dobro zdravlje i optimalna reprodukcija krava. Pravilna ishrana je polazna tačka za mlečne krave, da unesu optimalne količine suve materije (SM) hrane, koja je ključna za obezbeđenje dobre telesne kondicije (BSC) i visoke proizvodnje mleka. Zadovoljavajući unos SM u tranzicionom periodu, omogućava da krave posle teljenja budu što je moguće kraće vreme u negativnom energetskom bilansu (NEB). Najkritičniji period za krave je nedelja pre i posle teljenja. Ako negativan energetski bilans kraće deluje na kravu, to ima pozitivan efekat na proizvodnju mleka i reprodukciju, tj. servis period mlečnih krava. Kod mlečnih krava veoma značajno je sprečiti metaboličke poremećaje izazvane neadekvatnom ishranom, jer oni imaju reprekusije na proizvodnju i plodnost. Praćenjem zasušenja krava, toka teljenja, puerperalnih oboljenja i metaboličkih poremećaja u puerperijumu, do 42. dana posle telenja, značajno se smanjuje neplodnost mlečnih krava. Otkrivanje estrusa, rana dijagnoza graviditeta preko progesteronskog profila mleka, upotreba ultrazvuka u dijagnostici graviditeta, omogućavaju postizanje optimalne plodnosti mlečnih krava od oko 85%. U ovom radu dat je pregled nekih od procedura koje omogućavaju postizanje optimalne reprodukcije mlečnih krava.
