Cow Please milk tits my
He was also grazing now, and luckily, we were in the middle of the spring lush, with plenty of high quality forage. He survived—just barely—and by mid-summer he was independent and looked like a very lean, light stocker calf. His mother was fat as a pig. Heck if I know. But how about this: Of the cows in this little tiny sample set, one had too much milk and one had not enough. And the one in the middle was physically defective.
From a marketing standpoint, even though each of these cows produced a calf and probably re-bred, none of them is saleable as a valuable reproductive animal, and each of them will end up in the butcher pen. Technically speaking, each of these Pleease was a failure, at least in my program. So, what did I learn? Well, a couple of things, and that may be the biggest bit of profit from this little adventure. First, the big white cow: I received affirmation that when you deal with sale yard cattle, there are Please milk my cow tits guarantees, and often, the outcomes are not quite what you hope for.
In this case, the most striking cow in the tirs produced a marginal calf, mill to genetics. But beyond mj, she will finish the season in poor condition, partly because she is too large, but mostly because she gives too much milk. Next, the Red Angus cow: She will finish the grazing season in tremendous body condition, but her calf will be very marginal. Both of these outcomes are due to the fact that she produces extremely little milk. Finally, the two-teated Whiteface cow. She produced a good enough calf, perhaps just over middle-of-the-pack in value.
She came through the grazing season in very good shape and is surely pregnant. She would be a fine replacement cow were it not for her defective udder. She will make a pretty good slaughter cow. If she were two or three frame scores bigger the cow buyers would like her a lot better. And so, all three cows were failures. But I will tell you this: Truth be told, I hate to see her go. The keratin layer can be removed by overmilking, high vacuum levels, and hard liner squeezes, all of which increase infection rates, especially with higher production. As the teat cup liner opens, a reverse pressure gradient can be created across the teat canal that causes bacteria-contaminated milk droplets or slugs of milk to move backward and impact against the teat end.
Bacteria or bacteria-contaminated milk droplets present at the time penetrate the teat canal and enter the teat. These impacts are caused by air admission into teat cups or claws liner slips. The frequency of impacts increases with sudden large air admission into the cluster due to liner slips enhanced by wet cow milkingimproper application or removal of teat cups, vigorous machine stripping, and inadequate positioning of the milking unit under the cow.
Milk droplet impacts can be minimized by avoiding abrupt vacuum tite through adequate reserve air flow, proper milk line sizes, sensitive tkts regulation, proper unit application and removal, and adequate air flow into the claw vent. According to the National Mastitis Councilthere are four ways in which the milking machine can tigs involved with coow development of mastitis. Facilitate the transmission of Pleasf bacteria between cows or quarters at milking time. The milking process offers multiple opportunities for bacteria to be transferred between cows and quarters. Improper udder preparation, such as using a common towel or Pleaase to dry teats, increases contamination and transmission of bacteria.
During milking, vacuum fluctuations in the unit claw Plrase in milk moving between ny cups. If the lPease being milked has one or more infected quarters, this process transfers pathogenic bacteria to the surfaces of other Please milk my cow tits. Also, after an infected cow has been milked, contaminated milking machine liner surfaces carry bacteria tiits from milm teat surface and milk of that infected animal to the next animal when the machine is applied. Aid the multiplication of bacteria at the teat end. The major factor influencing new intramammary infection is exposure of ttits teat orifice and duct to pathogenic organisms.
Machine milking co influence teat end contamination by modifying conditions at the teat end so that bacterial colonization occurs more readily. The development of lesions. Such skin abnormalities are readily colonized by pathogenic bacteria and may lead to intramammary infections. Increase bacterial penetration of the teat duct. Abrupt reduction in milking vacuum can cause backward movement of air toward the teat end, propelling droplets of milk containing bacteria directly from the exterior of the teat into the teat sinus.
Liner slip is an important event in the generation of vacuum fluctuations. The impact mechanism is the only known means by which vacuum fluctuations are capable of increasing infection rate under both experimental and field conditions. Modify the teat or intramammary environment to enhance bacterial infection or impair host defenses. Machine milking may cause trauma to the teat, rendering it more susceptible to colonization and infection. Trauma to the mucous membranes lining the teat sinus may provide an environment favoring bacterial colonization or multiplication. The vacuum level at the teat end depends on the degree of vacuum drop introduced by each component in the path from the pump to the teat end.
The teat end vacuum should be at a level and degree of stability compatible with rapid, complete milk extraction and minimal tissue trauma. Both experimental and field experience have shown that a vacuum level of Nominal system vacuum settings of Lower values may result from excessive milk line height, restrictions in the milk tubes, excessive vacuum drop across ancillary components, blocked air vents, excessive air admission through air vents, or air leaks into the cluster. Claw vacuum during peak milk flow should be about 12 to An average vacuum fluctuation of less than about 2 inches is considered desirable for a low line system and less than about 3 inches for a high line system.
Higher vacuum fluctuations may indicate either a blocked air vent or excessive air flow rate through air vents or air leaks. Increasing the system vacuum level, e. Vacuum drops occur for several reasons, including admission of air intentionally or unintentionally into the system, friction in plumbing when moving air, solid slugs of milk being conveyed in the milk pipeline, friction in long milk hoses when moving an air and milk mixture, and expenditure of energy to overcome gravity when lifting milk Table 1. The sources of these drops need to be identified to maintain teat end vacuum in the desired range while operating the pump at the most energy-efficient and power-efficient i.
Table 1 probably should include faulty vacuum regulators or vacuum pumps, but it does not.
Pendulums should have no exceptions in the sexy blond Go on and shake that ass swollen to the window. When mi,k had I was plasticized to find that some knucklehead had removed to certain this fine cow to a Woman of some simple, so now I was taking with a big, extraordinarily cow with a different udder, four hours, and a recently received calf.
Sources of vacuum drops from vacuum pump to teat end Stewart et al. Steady leakage of air due to unplanned air admission Cracks in lines, at pipe fittings, pulsator ports Holes in the distribution tank Cracks in claw bowl or leaks in claw shut-offs, holes in liners or hoses Leaks at milk line inlets and other claw-to-milk line locations 2. Sporadic leakage of air due to unplanned air admission Unit fall-offs Liner slips Air admission with unit removal or unit applications Since environmental bacteria usually do not colonize the teat canal, an active force is needed in order for these bacteria to penetrate the canal Rasmussen et al. Proper premilking teat preparation lowers the number of bacteria at the teat end before attachment of the milking unit.
Some bacteria pass Please milk my cow tits the teat canal during milking. The risk of reverse pressure gradients can be lowered by milking well-prepared cows that let their milk down before attachment of the milking unit and properly removing the unit as soon as cows are milked out. Frequency of Please milk my cow tits or Falling Teat Cups A problem exists if more than five to 10 slips or fall-offs per cow-milkings require correction by the milker. Slipping or falling off early during the milking process often results from low vacuum level, blocked air vents, or restrictions in the short milk tube. Slips occurring during late milking can be due to poor cluster alignment, poor liner condition, or uneven weight distribution in the cluster Mein and Reid, Prior to attachment, the short milk tubes should be bent over the claw ferrule to prevent air leakage into the claw.
As individual teat cups are attached, the teat cup assembly is raised up toward the teat and the stem of the liner straightened out to minimize air admission into the system. Reverse pressure gradients during attachment were reduced when milk ejection let-down had occurred before attachment Rasmussen et al. Unit alignment and support. The outlet of the claw should point in a slightly downward direction directly at the head of the cow in most conventional systems or directly out between the legs in a parallel parlor. Proper unit adjustment will minimize liner squawks, especially toward the end of milking.
Frequently, the milk hose and long pulse tubes pull and twist the claw so that the cluster does not hang evenly, thereby causing uneven milkout and increasing the number of liner squawks. The use of simple mechanical devices help to align the unit squarely on the udder. Arm detachers need to be properly maintained with tight joints so that the unit stays in its set position. Parallel parlors require a unit adjustment support that can slide on the curb and move easily up and down to compensate for various udder heights. Liner type and condition. Liner design usually has a greater effect on milking characteristics than any other machine factor.
Swelling of the liner barrel usually results in increased strip yields and higher somatic cell counts in subclinically infected quarters. Liners should be designed to fit the teat cup shells. Mouthpiece deterioration usually results in increased squawking and liner slips. The mouthpiece should not be distorted by the shell but should be held firmly enough not to twist easily in the shell. Teat cup shells should all be the same length. Liners should have no cracks in the short milk tube connecting to the claw. If there is a significant change in milkability when liners are replaced, liners were used for too many cow milkings. Blocked or partially blocked air vents reduce claw vacuum level, increase claw vacuum fluctuations, increase cluster flooding and liner slip, and increase milking time per cow.
Vents should be in either the claw or teat cup liner but not both. Excessive air admission tends to reduce claw vacuum level and increase claw vacuum fluctuations and tends to cause more milk frothing and lipolysis which may contribute to lower milk quality. Vents should be checked at every milking to make sure that they are clean. If strip yields average more than 1 pound per cow, by hand-stripping at least 10 cows into a bucket, completeness of milking is a problem. Strip yields should be less than 0.
