CZ305535B6 - Teat cup for milking sheep - Google Patents

Abstract

The present invention relates to a sheep milking teat cup, which is characterized in that the upper portion of the teat cup housing (1) is curved such that a line perpendicular to the plane of the teat sleeve (2) forms with the longitudinal axis of the lower portion of the teat cup housing (1) an angle deferring to skew position of the teats on the sheep udder.

Description

Teat handpiece for milking sheep

Technical field

The invention relates to the curved shape of a teat cup sleeve for machine milking sheep.

BACKGROUND OF THE INVENTION

The morphological structure of the udder is different for different types of livestock used for dairy production. In sheep, the vertical position of teats, which is common in cattle, occurs very rarely. The teats of the sheep are predominantly situated on the sides of the udder and usually point sideways. In our previous investigations we found average values of the angle between the teat axis and the vertical of 37.5 ° (sd = 10.2 °), for the Gypsy breed 40.8 ° (sd = 11.6 °), for the Breed Valaška breed and 46 , 9 ° (sd = 14.5 °), in the Lacaune breed in Slovakia (Milerski et al., 2006). For Czech dairy sheep populations the average values of this indicator according to preliminary, so far unpublished results are 40.8 ° (sd = 6.5 °), for crossbreeds Lacaune and Šumava sheep and 43.6 ° (sd = 9.2 °) for East Frisian sheep.

The shape of Magpie handpieces used for milking sheep is based on the construction of handpieces used in cattle, which have a straight sheath and whose longitudinal axis takes a position close to the vertical during milking. In many cases, in the case of sheep with more horizontally situated magpies, they are kinked or the air is sucked from the lateral side of the teat. Some sheep even need to hold the teat cups in the correct position manually during milking. Furthermore, in many cases, the deployment of the Magpie handpieces is problematic, when the opposite half of the udder needs to be lifted, whereby the teat axis is brought to a more vertical position and the teat cup can be fitted from below.

For the reasons given above, the morphological structure of the udders is currently being given great attention in breeding programs in dairy sheep breeding, with the aim of selecting animals with vertically teats for breeding. However, breeding is a long-term issue and, in addition, completely vertical teats can be problematic in terms of suckling lambs. Therefore, it is necessary to adapt the milking technique to the morphological characteristics of sheep udders along with the adaptation of the animals to the milking requirements.

SUMMARY OF THE INVENTION

The above-mentioned drawbacks are eliminated by the milking teat cup of the present invention, wherein the upper portion of the teat cup casing is curved according to the teat position on the sheep udder such that a line perpendicular to the teat cup mouth lies at the longitudinal axis of the lower teat cup casing. an angle of 20 to 40 °, wherein the teat cup sleeve is provided at its upper mouth with a flange for fastening the teat sleeve such that its mouth is rotated in the direction of curvature of the teat cup sleeve.

The sheep milking teat cup according to the invention is further characterized in that a line perpendicular to the plane of the teat cup mouth forms an angle of 30 ° with the longitudinal axis of the lower portion of the teat cup housing.

The teat cup according to the invention is also characterized in that the teat cup sleeve to be mounted on the right teat of the milked sheep is viewed from the rear or in the rear, respectively. from the direction of the outlet of the pulse vacuum hose sleeve and the milk hose sleeve, curved to the left, the left teat cup sleeve being curved to the right.

The essence of the teat cup for milking sheep according to the invention is therefore to adapt the shape of the teat cup to the inclined position of the teats in the udder of the sheep. The advantage is that during milking, the teat is not so much deviated from its natural position in most animals and milking is more comfortable for sheep. The design and weight distribution of the sheep milking teat cup according to the invention facilitates their placement on oblique teats where a slight rotational movement can be used (no need to move teats before deployment) and further reduces the risk of sliding and falling the sleeve fits better to the teat base on its lateral side and, moreover, the gravitational force vector is not parallel to the teat axis during milking, as is the case with the classic teat cup shape. The inventors have found it useful when the teat cup sleeve was made of plastic and the teat sleeve was made of silicone. Stainless metal appears to be another suitable material for the sleeve housing, and the teat sleeve can also be made of rubber. The milking of sheep with a teat handpiece according to the invention was clearly more suitable for sheep than the milking of the prior-art straight Magpie handpieces. The sheep were now calmer when milking and milking was faster as well, since the slag handpiece of the invention fits well with the udder.

The sheep milking teat cup of the present invention is adapted to the tilt of the teats of the sheep, thereby allowing them to be easier to put on the udder, reducing milking kits falling during milking, and reducing teats during milking caused by turning them into an unnatural position.

DETAILED DESCRIPTION OF THE INVENTION

Example 1

The sheep milking teat cup according to the invention consists of a teat cup housing 1 made of stainless steel, plastic or other suitable material and a rubber or silicone teat sleeve 2. The upper half of the sheep milk teat cup and cup according to the invention is curved so that a straight line perpendicular to the plane of the mouth of the teat sleeve 2 forms an angle of 30 ° with the longitudinal axis of the lower part of the teat cup sleeve. This value of the angle represents a compromise between the current average teat angulation values of dairy sheep breeds in the Czech Republic and Slovakia on the one hand and the effort to achieve a taller teat position in milked sheep populations by breeding on the other. At the upper orifice, the teat cup sleeve 1 is provided with a flange 6 for fastening the teat sleeve 2, while at the lower end rear 2 nozzles open: a sleeve 3 for connecting a pulsating vacuum hose and a milk hose sleeve 4. Due to the location of the sleeves 3 and 4, the left and right teat cups are of different construction. The sheep milking teat cup according to the invention intended to be attached to the right teat 5 of the sheep is rearwardly curved to the left, while the teat cup intended to be fitted to the left teat 5 is curved to the right. The teat handpiece according to the invention has been successfully tested in the milking of 81 sheep on the Beskid hut in Istebna (breeder H. Kukuczka, 43-470 Istebna, Poland).

Industrial applicability

By using a teat cup for sheep milking, the machine milking of sheep can be made more efficient by facilitating the placement of teat cups on the udder, reducing milking kits falling during milking and reducing teats during milking caused by turning them into an unnatural position.
