Dry Cow
A dry cow refers to a dairy cattle, dairy cow that is in a stage of their lactation cycle where milk production ceases prior to Calf (animal), calving. This part of their lactation cycle is referred to as the cows dry period and typically last between 40 and 65 days. Dry cows are typically divided into two groups: far-off (60–21 days before calving) and close-up (21 days to calving). Once the cow has entered this stage, producers will seal the cows teat while following a veterinarian recommended, dry cow therapy for their herd. This dry period is a critical part of their lactation cycle and is important for the cows health, the newborn calf and future milk production, as it allows the cow time to rest, eat and prepare for birth. During this time, the cow will produce colostrum for the newly born calf. Research has shown that this period impacts overall milk production yields during their next lactation. Dry periods that are too short have been associated with reduced milk yields a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breasts Of Cow2
The breast is one of two prominences located on the upper ventral region of a primate's torso. Both females and males develop breasts from the same embryology, embryological tissues. In females, it serves as the mammary gland, which produces and secretes milk to feed infants. Subcutaneous fat covers and envelops a network of lactiferous duct, ducts that converge on the nipple, and these tissue (biology), tissues give the breast its size and shape. At the ends of the ducts are mammary lobule, lobules, or clusters of mammary alveolus, alveoli, where milk is produced and stored in response to hormone, hormonal signals. During pregnancy, the breast responds to a complex interaction of hormones, including estrogens, progesterone, and prolactin, that mediate the completion of its development, namely lobuloalveolar maturation, in preparation of lactation and breastfeeding. Humans are the only animals with permanent breasts. At puberty, estrogens, in conjunction with growth hormon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parenchyma
Parenchyma () is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology it is the name for the tissue that fills the interior of flatworms. Etymology The term ''parenchyma'' is New Latin from the word παρέγχυμα ''parenchyma'' meaning 'visceral flesh', and from παρεγχεῖν ''parenchyma'' meaning 'to pour in' from παρα- ''para-'' 'beside' + ἐν ''en-'' 'in' + χεῖν ''chyma'' 'to pour'. Originally, Erasistratus and other anatomists used it to refer to certain human tissues. Later, it was also applied to plant tissues by Nehemiah Grew. Structure The parenchyma is the ''functional'' parts of an organ (anatomy), organ, or of a structure such as a tumour in the body. This is in contrast to the Stroma (animal tissue), stroma, which refers to the ''structural'' tissue of organs or of structures, namely, the connective tissues. Brain The brain parenchyma refers to the functional tissue in the brain that is made up of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Milk Fever
Milk fever, postparturient hypocalcemia, or parturient paresis is a disease, primarily in dairy cattle but also seen in beef cattle and non-bovine domesticated animals, characterized by reduced blood calcium levels (hypocalcemia). It occurs following parturition, at onset of lactation, when demand for calcium for colostrum and milk production exceeds the body's ability to mobilize calcium. "Fever" is a misnomer, as body temperature during the disease is generally not elevated. Milk fever is more commonly seen in older animals (which have reduced ability to mobilize calcium from bone) and in certain breeds (such as Channel Island breeds). Clinical signs The clinical signs of milk fever can be divided into three distinct stages: Stage 1 Cows are mobile but show signs of hypersensitivity and excitability such as restlessness, tremors, ear twitching, head bobbing, and mild ataxia. If not treated, symptoms usually progress to stage 2. Stage 2 Cows can no longer stand and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Milk Cows In The Netherlands 02
Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) before they are able to digest solid food. Immune factors and immune-modulating components in milk contribute to milk immunity. Early-lactation milk, which is called colostrum, contains antibodies that strengthen the immune system, and thus reduces the risk of many diseases. Milk contains many nutrients, including protein and lactose. As an agricultural product, dairy milk is collected from farm animals. In 2011, dairy farms produced around of milk from 260 million dairy cows. India is the world's largest producer of milk and the leading exporter of skimmed milk powder, but it exports few other milk products. Because there is an ever-increasing demand for dairy products within India, it could eventually become a net importer of dairy products. New Zealand, Germany and the Netherlands are the largest exporters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat Stress
Hyperthermia, also known simply as overheating, is a condition in which an individual's body temperature is elevated beyond normal due to failed thermoregulation. The person's body produces or absorbs more heat than it dissipates. When extreme temperature elevation occurs, it becomes a medical emergency requiring immediate treatment to prevent disability or death. Almost half a million deaths are recorded every year from hyperthermia. The most common causes include heat stroke and adverse reactions to drugs. Heat stroke is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms of the body. The latter is a relatively rare side effect of many drugs, particularly those that affect the central nervous system. Malignant hyperthermia is a rare complication of some types of general anesthesia. Hyperthermia can also be caused by a traumatic brain injury. Hyperthermia differs from fever ...

Pasture
Pasture (from the Latin ''pastus'', past participle of ''pascere'', "to feed") is land used for grazing. Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing. Pasture lands in the narrow sense are distinguished from rangelands by being managed through more intensive agricultural practices of seeding, irrigation, and the use of fertilizers, while rangelands grow primarily native vegetation, managed with extensive practices like co ...

Mastitis In Dairy Cattle
Bovine mastitis is the persistent, inflammatory reaction of the udder tissue due to physical trauma or microorganisms infections. Mastitis, a potentially fatal mammary gland infection, is the most common disease in dairy cattle in the United States and worldwide. It is also the most costly disease to the dairy industry. Milk from cows suffering from mastitis has an increased somatic cell count. Prevention and control of mastitis requires consistency in sanitizing the cow barn facilities, proper milking procedure and segregation of infected animals. Treatment of the disease is carried out by penicillin injection in combination with sulphar drug Definition Mastitis occurs when white blood cells (leukocytes) are released into the mammary gland, usually in response to bacteria invading the teat canal or occasionally by chemical, mechanical, or thermal trauma on the udder. Milk-secreting tissue and various ducts throughout the mammary gland are damaged due to toxins released by the ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
