Abstract

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 eliminate
some 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 vacuum
during 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 installed
separately. It was found that, at an average flow rate of 4.8 l min-1, the average vacuum in the liner during the bphase was 35.0 kPa in CON, 32.6 kPa in BIO and 31.1 kPa in the MULTI system, compliant with the desired
average vacuum in the liner of 32-42 kPa mentioned in ISO 5707 (2007). The average liner vacuum values during
the d-phase differs from one system to another and these values were calculated to be 34.2 kPa, 12.3 kPa and 14.8
kPa for CON, MULTI and BIO, respectively. The reason why CON differs as compared to MULTI and BIO can be
attributed to the fact that both, MULTI and BIO use the BioMilker system that allows periodic air ingress under the
teat

Abstract

Geçen 100 yıl boyunca sağım makinasının meme sağlığı üzerine etkileri farkedilmiştir. Farklı sağım sistemleri arasında, 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 bir pençesiz sağım sistemi geliştirilmiştir. Yapılan bu çalışmanın amacı, ISO 6690 (2007)’da tanımlanmış yaş deneme yöntemini kullanarak, üç sağım sisteminde nabız hareketinin b ve d fazlarında ortalama meme lastiği vakum basıncı değerine, süt debisinin etkisini belirlemektir. Ölçümler CON, BIO ve MULTI sağım sistemlerinin ayrı ayrı kurulu olduğu farklı sağımhanelerde gerçekleştirilmiştir. 4.8 l min-1 sağım debisinde, b fazı sırasındaki ortalama meme lastiği 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. d fazındaki meme lastigi vakum değerleri sistemler arasında farklılık göstermekte olup bu değerler CON’da 34.2 kPa,MULTI’de 12.3 kPa ve BIO’da 14.8 kPa olarak saptanmıştır. CON ile diğer iki sistem arasında ortaya çıkan bu büyük farkın sebebi, Multilactor’ün meme başı alt kısmına periyodik hava girişine izin veren “Biomilker” adı verilen sisteme sahip olmasıdır.
