“…Nevertheless, today it is not uncommon for cows to be more productive; therefore, this milking frequency may be insufficient. Studies have shown that, when milking high-yielding cows three times a day (compared to milking twice a day), the milk yield increases by 10-15 %, but after switching to four milking times a day -by up to 22 % [8][9][10]. Moreover, it has been found that a further increase in the milking frequency is not desirable, as it is not possible to produce full milk ejection reflex at very short intervals (shorter than 4-5 hours), resulting in disturbances in the milk output process [11].…”

Abstract. The main problem in using the AMS is that cows do not attend the AMS voluntarily. To ensure milking three or four times a day, in many farms cows are driven to the AMS several times a day. Representatives of companies recommend that it only takes place at the beginning and at the end of a workday. In such a case, cows gradually get used to milking as many times a day as it is intended. However, the question is -does this really happen? Next to the concern regarding the provision of the intended milking times a day, farmers are also worried about milking interval dispersion. Appropriate studies were carried out to see what happens in farms, where cows are driven to the AMS in the morning and in the evening only. At the same time, analogous studies were carried out in a holding, where cows were milked with milking parlour. The studies were conducted in two holdings. In the first holding, cows were milked with the AMS, but in the second -with parallel parlour. Ten cows were selected for each experimental group, and the studies lasted for 15 days. They determined the number of milking times per day (milking/day), and the distribution and dispersion of milking intervals. The results of the study showed that in practice it was possible to achieve that the AMS is attended more than 3 times a day, on the condition that only cows with a milking interval of more than 13 hours are driven to the milking site in the morning and in the evening. However, at the same time it was found that there would always be cows in a herd that have been milked both more and less than three times a day. When milking with the AMS, milking intervals vary widely, yet in 80 % of the cases they vary between 5 and 6 hours. First lactation cows (as compared to older cows) are more inert to attend the AMS, and their dispersion of milking intervals is greater. In turn, milking parlour ensures that all cows undergo the set number of milking times and it helps keep smaller fluctuations in milking intervals. If 60 to 80 cows are milked in one group, the fluctuation of the milking interval does not exceed 2 hours. Keywords: milking, AMS, parlours, intervals. IntroductionToday, the automatic milking systems (AMS) are widely used both in Latvia and in other EU countries. In the survey involving owners of dairy farms in Latvia, who use the AMS, the reluctance of cows to attend the AMS voluntarily was underlined as a key problem for the use of the AMS. In order to ensure milking of high-yielding cows three or four times a day, as recommended by best dairy farming practices, it is very often necessary to drive cows to the AMS several times a day, and it increases the workload of livestock keepers. In turn, representatives of AMS manufacturing companies claim that it is enough to drive the "lazy" cows to the milking site only at the beginning and at the end of a workday. If the cows are not bothered at other times, they will get accustomed to such an order and will attend the AMS on a regular basis. However, given the results of the farm owner survey...

“…Many researchers have observed no effect of frequent milking on milk composition (Poole, 1982;Rao & Ludri, 1984;Amos et al, 1985;DePeters et al, 1985;Gisi et al, 1986), whereas some have observed a decrease in fat percentage (Allen et al, 1986;Smith et al, 2002). Due to the increase in milk production in response to frequent milking, however, there is often an increase in the total yield of fat and protein (Klei et al, 1997;Dahl et al, 2004b).…”

“…Due to the increase in milk production in response to frequent milking, however, there is often an increase in the total yield of fat and protein (Klei et al, 1997;Dahl et al, 2004b). With respect to SCC, some reports have indicated an association between frequent milking and decreased SCC, and these authors concluded that frequent milking may improve mammary health (Poole, 1982;Armstrong et al, 1985;Smith et al, 2002;Dahl et al, 2004b). Others have reported no effect of frequent milking on SCC (Waterman et al, 1983;DePeters et al, 1985;Gisi et al, 1986;Bar-Peled et al, 1995;Klei et al, 1997;Hale et al, 2003;Patton et al, 2006;Wall & McFadden, 2007a;Shields et al, 2011;Wright et al, 2011).…”

“…Some researchers have observed decreased reproductive performance in 3X cows compared to 2X cows (Ludwin, 1942;Armstrong et al, 1985;DePeters et al, 1985;Smith et al, 2002), whereas others have observed no effect (Poole, 1982;Amos et al, 1985;Gisi et al, 1986) or an improvement (Allen et al, 1986) in reproductive performance with 3X. Armstrong et al (1985) suggested that any negative effects of frequent milking on herd health or reproductive performance may be associated with poor herd management.…”

“…A number of studies demonstrated the advantages and disadvantages of this practice, including increase in milk production (Amos et al, 1985;DePeters et al, 1985;Bar-Peled et al, 1995;Alves, 2004;Negrão, 2004;Dahl, 2005;Gama & Lopes, 2008;Bernier-Dodier et al, 2010), changes in milk composition (Waterman et al, 1983;Amos et al, 1985;DePeters et al, 1985;Allen et al, 1986;Klei et al, 1997), effect on cow health and reproduction (Jarrett, 1977;Logan et al, 1978;Poole, 1982;DePeters et al, 1985;Allen et al, 1986;Moya et al, 2008) and feed intake and metabolism (Kelly et al, 1998;Smith et al, 2002). However, none addressed the issue of economic viability.…”

RESUMOViabilidade econômica da terceira ordenha em sistemas de produção de leite com ordenhadeira de circuito fechadoObjetivou-se, com este trabalho, analisar a viabilidade econômica da terceira ordenha, em sistemas de produção de leite com ordenhadeira mecânica, do tipo circuito fechado, visando a fornecer aos técnicos e pecuaristas informações que os auxiliem nas tomadas de decisões. Especificamente, pretendeu-se, ainda: a) estimar o custo de uma ordenha; b) estimar o custo da terceira ordenha; c) desenvolver uma equação matemática que permita estimar a quantidade mínima de leite produzida em duas ordenhas, a partir da qual será viável economicamente a realização da terceira ordenha. Os dados foram coletados em três propriedades leiteiras, de novembro de 2010 a março de 2011, em uma rotina de duas ordenhas diárias, sendo realizadas três coletas de dados em cada uma, perfazendo um total de nove. Considerando-se os dados médios, seria viável a realização da terceira ordenha se a produtividade média diária das vacas em lactação, em duas ordenhas, fosse igual ou superior a 24,43 kg de leite.Palavras-chave: bovinocultura leiteira, custo de produção, economia, frequência de ordenhas. This study aimed to analyze the economic viability of the third milking in production systems using mechanical milking in a closed circuit, aiming to provide technicians and farmers with information to assist them in decisionmaking. Specifically, it intended: (a) to estimate the cost of one milking; (b) to estimate the cost of the third milking; (c) to develop a mathematical equation to estimate the minimum amount of milk produced with two milkings, from which it would be economically feasible to do the third milking. Data were collected from three dairy farms, from November 2010 to March 2011, keeping a twice-a-day milking frequency, with three data collections in each farm, totalizing nine collections. Considering the average data, it would be feasible to do the third milking if the average milk yield per day of lactating cows in a twice-a-day milking frequency was greater than or equal to 24.43 kg of milk.
