Comparison of the vacuum dynamics of conventional andquarter individual milking systems

Geçen 100 yıl boyunca sağım makinasının meme sağlığı üzerine etkileri farkedilmiştir. Farklı sağım sistemleriarasında, geleneksel sağım sistemlerinin (CON) ve periyodik hava girişi olan geleneksel sağım sistemlerinin (BIO),meme sağlığı üzerindeki zararlı etkilerini ortadan kaldırmak amacıyla Multilactor (MULTI) adı verilen yeni birpençesiz sağım sistemi geliştirilmiştir. Yapılan bu çalışmanın amacı, ISO 6690 (2007)’da tanımlanmış yaş denemeyöntemini kullanarak, üç sağım sisteminde nabız hareketinin b ve d fazlarında ortalama meme lastiği vakum basıncıdeğerine, süt debisinin etkisini belirlemektir. Ölçümler CON, BIO ve MULTI sağım sistemlerinin ayrı ayrı kuruluolduğu farklı sağımhanelerde gerçekleştirilmiştir. 4.8 l min-1sağım debisinde, b fazı sırasındaki ortalama memelastiği vakum basıncı değeri CON’da 35 kPa, BIO da 32.6 kPa ve MULTI’de 31.1 kPa olarak bulunmuştur. Bu değerler ISO 5707 (2007) de vurgulanan 32-42 kPa’lık arzu edilen basınç değerlerine uyum göstermektedir. dfazındaki meme lastigi vakum değerleri sistemler arasında farklılık göstermekte olup bu değerler CON’da 34.2kPa,MULTI’de 12.3 kPa ve BIO’da 14.8 kPa olarak saptanmıştır. CON ile diğer iki sistem arasında ortaya çıkan bubüyük farkın sebebi, Multilactor’ün meme başı alt kısmına periyodik hava girişine izin veren “Biomilker” adı verilensisteme sahip olmasıdır.

Geleneksel ve pençesiz sağım sistemlerinin vakumdinamiklerinin karşılaştırılması

The effect of machine milking on udder health has been recognized for the past 100 years. Among different milking systems, a new quarter individual milking system called the Multilactor ® (MULTI) has been developed to eliminatesome detrimental effects of conventional milking systems (CON) and conventional systems with periodic air ingress(BIO) on udder health. The objective of this study was to determine the effects of milk flow on average liner vacuumduring the b and d phases of pulsation in all systems by using a wet-test method defined in ISO 6690 (2007).Measurements were conducted in three different milking parlours where CON, BIO and MULTI were installedseparately. It was found that, at an average flow rate of 4.8 l min-1 , the average vacuum in the liner during the b- phase was 35.0 kPa in CON, 32.6 kPa in BIO and 31.1 kPa in the MULTI system, compliant with the desiredaverage vacuum in the liner of 32-42 kPa mentioned in ISO 5707 (2007). The average liner vacuum values duringthe d-phase differs from one system to another and these values were calculated to be 34.2 kPa, 12.3 kPa and 14.8kPa for CON, MULTI and BIO, respectively. The reason why CON differs as compared to MULTI and BIO can beattributed to the fact that both, MULTI and BIO use the BioMilker system that allows periodic air ingress under theteat.
