“…Due to the unique morphological and anatomical characteristics of each species, machines with specific attributes in terms of the amount of time and negative pressure are required. Various studies have been conducted to perfect these automated milking machines for sheep and goat, with excellent results [112][113][114][115].…”

Precision livestock farming (PLF) has spread to various countries worldwide since its inception in 2003, though it has yet to be widely adopted. Additionally, the advent of Industry 4.0 and the Internet of Things (IoT) have enabled a continued advancement and development of PLF. This modern technological approach to animal farming and production encompasses ethical, economic and logistical aspects. The aim of this review is to provide an overview of PLF and Industry 4.0, to identify current applications of this rather novel approach in different farming systems for food producing animals, and to present up to date knowledge on the subject. Current scientific literature regarding the spread and application of PLF and IoT shows how efficient farm animal management systems are destined to become. Everyday farming practices (feeding and production performance) coupled with continuous and real-time monitoring of animal parameters can have significant impacts on welfare and health assessment, which are current themes of public interest. In the context of feeding a rising global population, the agri-food industry and industry 4.0 technologies may represent key features for successful and sustainable development.

“…The different sensors, lengths of the hoses, vacuum and pulsation settings, and delay time (DT) settings, whereas is electronic, mechanic or count the slugs, are the reasons explaining this trend. The ACR component in the small ruminant is the automatic vacuum shut off system (AVSO; Alejandro, 2016) or the automatic vacuum cutting devices system (Bueso-Rodenas et al, 2014). These systems have the advantage of the cluster not being manually removed by the milker.…”

“…On the other hand, if the animal has a mild milk flow at take-off, then the take-off milk flow will be very close to the pre-set milk flow for the take-off. Moreover, DT is important if the milk flow returns to values that are above the threshold milk flow, a case in which the teat-cup should not be removed from the udder (Bueso-Rodenas et al, 2014). This is particularly important in animals that have a milk flow curve with two peaks, where the second peak means alveolar milk ejection milk.…”

“…Consequently, there is more exposure to liner compression and vacuum load on the teat. Therefore, these results favour the notion of simplifying and automating the end of milking procedures, as there has been a recent increase in ACR utilization which increases small ruminant farm efficiency (Bueso-Rodenas et al, 2014). The aim of this article is to review present milking routines and cluster removal strategies in small ruminants based on different milk flow profiles associated with different anatomical and physiological conditions.…”

Small ruminants not only differ on mammary gland anatomy, milk’s properties and the amount of milk yielded comparable to those of dairy cattle, but also on the milking routine strategies and machine milking settings to maximize daily milk secretion. The udder compartment is proportionally larger in dairy sheep and goats, which requires modifications in the milking machine settings, milking procedures and allows the use of different milking strategies as they better tolerate extension of milking intervals. Depending on the breed, cisternal milk in goats varies from 70% to 90%, whereas in dairy sheep it varies from 50% to 78% of the total gland capacity. This explains why these species are commonly milked without pre-milking teat preparation, while in goats it is applied only in cases of high prevalence of intramammary infection in the herd. Recent French researchers observed that 40% of the goats presented an unbalanced udder as well as unbalanced morphology (21% to 30%) and functional milk flow (around 10% to 20% more) which could induce overmilking. In dairy sheep, selection for higher milk production increases teat angle insertion. Thus, to increase machine milk fraction, it is recommended to use either the ‘Sagi hook’ as an alternative for lifting up the ‘pendulous’ udder during milking or to perform machine stripping. There are three cluster removal strategies for small ruminants: manual, timed and milk flow driven automatic cluster removal (ACR). Automatic cluster removal reduces overmilking, improves teat condition, enables labour saving and provides a consistent milking routine in small ruminants. There are three to five main milk flow profiles in ewes and goats, which result in curves with one or two peaks (or plateau) and different patterns of the milk flow decreasing phase due to the degree of mammary gland imbalance and teat characteristics. When taking into account our current knowledge, ACR recommended take-off settings for goats are: 200 g/min+10 s delay time (DT) for a long decreasing phase or two plateau curves and 500 g/min+5 s DT for a short decreasing phase and one plateau curve. The ACR take-off settings for ewes are: 150 g/min +10 s DT for long decreasing phase and 200 g /min+5 s DT for a short decreasing phase. This review is intended to be useful for scientists and producers seeking basic knowledge of milking routines and cluster detachment settings for parlour performance and milk quality.
