Traite a La Machine Des Brebis Préalpes Du Sud. Importance Des Différentes Opérations De La Traite

Abstract: jou!,-eit-josas (Seivce-el-Oise) SOMMAIRE Les brebis l'véalj!es du Sud utilisées dans ces expériences ont été traites à la machine 2 fois par jour. Chaque traite comprenait 3 opérations : 1°) la « traite machine » proprement dite, de la pose des gobelets à la fin de l'écoulement du lait ; 2°) un égouttage machine avant l'enlèvement des gobelets ; 3°) un égouttage manuel ou « repasse ». L'importance de la quantité de lait obtenue au cours de ces 3 opérations, exprimée en p. roo du total de lait trait, varie du … Show more

“…In this way cows tend to be machine stripped, manually or with automated stripping devices (Dethlefsen et al, 1990;Hamann and Dodd, 1992), applying extra weight or traction to the teatcup. This pressure results in a partial, but temporary, reopening of the milk passageway to the teat sinus Kinetic emission was determined repeatedly for the morning milking in the last 2 d of each weekly period, following the manual method described by Ricordeau et al (1963), but recording the milk flow every 5 s. Ewes were classified with 1 emission (without ejection reflex) or 2 emissions (with ejection reflex) according to Labussi6re et al (1969). The incidence of teatcup falls was recorded with the same frequency as production.…”

“…A second linear regression analysis was performed, with dependent variable the manually measured volume ( V f ( t )) [2] and the predicted volume ( V p ( t )) by the calibration model (Table 1) as independent variable. The model fitting is shown in Figure 4, which is a significant model (P-value < 0.01), with intercept near cero and a slope near 1 in Equation (2), a percentage of explanation (R 2 ) of 99.962%, and a mean absolute error of 0.054 L: Vf(t)=-3.95×10-8+1×Vp(t).…”

“…Milking parameters were rate of 90 pulsations per minute, vacuum level of 40 kPa, and 60% pulsation ratio. Five goats of Murciano-Grenadine race were milked, with a milk production ranging between 1.2 and 4 L. The milk flow was recorded according to the method in [2], so that the volume milked was manually recorded (according to the scale of the proportional meter) every 5 s, while, at the same time, the milk production was recorded by the electronic system every second. The verticality of the apparatus was ensured by holding a weight of 1 kg of the WB Mini-Test (Tru-Test).…”

“…These routines were constant during the last decades, but they have started to slowly change due to the increase in the number of animals and milk production, udder morphology, and with more prevalent automation of the farms. The oldest complex milking routines included double cluster attachment, intense pre-stimulation (scarce), machine milking, and machine stripping followed by hand stripping called 'repasse' (Ricordeau et al, 1963;Bueso-Rodenas et al, 2015). Thereafter, the milking routine was simplified to including teat-cup attachment, machine milking, machine stripping and manual teat-cup removal.…”
