Formulating Diets for Groups of Lactating CowsDAIReXNET
Dr. Bill Weiss of The Ohio State University presented this material for DAIReXNET on February 26, 2015. For the full presentation, please visit our archives at http://www.extension.org/pages/15830/archived-dairy-cattle-webinars
Farm animals have well known zones of thermal comfort (ZTC). The range of ZTC is primarily dependent on the species, the physiological status of the animals, the relative humidity and velocity of ambient air, and the degree of solar radiation. Economic losses are incurred by the U.S. livestock industries because farm animals are raised in locations and/or seasons where temperature conditions venture outside the ZTC. The objective of this presentation is to provide current estimates of the economic losses sustained by major U.S. livestock industries from thermal stress and to outline future challenges as animal productivity is improved. Species (production) considered are: chicken (meat), chicken (eggs), turkey (meat), cattle (meat), cattle (milk), and pig (meat).

cattle and poultry farming
It is a class note for cattle and poultry farming course. it also can be use in animal science. In this portion we disscuss about the care of a cattle.
It is a disaccharide composed of the monosaccharides glucose come from blood and galactose ( ??) synthesized in golgi apperatus in mammary gland both linked by glycosidic link.
It is only found in milk in its natural state , synthesized in mammary gland.
It is found in form of opaque solution.
Less sweet than sucrose. (5% sucrose=10% lactose) (double).
Low soluble--- crystalization
Fermentation
Maillard reaction
In order to digest lactose, your body digestive tract produces the enzyme lactase. Lactase is produced by the small intestine and secreted to break down lactose into its simpler forms of sugar—glucose and galactose. These simple sugars are easily absorbed into the bloodstream and used as energy.

Understanding Equine Metabolic Syndrome by SmartPak Equinesusantuller
Are you struggling to help your "chubby" horse slim down? Do terms like "IR" and "EMS" have you feeling confused? We can help! Our equine health experts, Dr. Gray and Jessica, will be hosting a live discussion on obesity, insulin resistance and managing the "easy keeper."

The National Licensure Examination for Veterinarians (NLEV) is a national examination developed by the Nepal Veterinary Council, as pre-requisite for NVC registration. This National Licensure Examination for Veterinarians (NLEV) is required for all new graduates of Bachelor of Veterinary Science and Animal Husbandary (B.V.Sc. & A.H.) or B.V.Sc. or D.V.M or M.Sc. (Vet.). The examination is geared towards testing knowledge and skills in relation to the job functions most commonly required by entry-level veterinarians. The examination determines eligibility to earn a title of registered veterinarians, to begin his/her service as a professional veterinarian.

Grouping and nutritional strategies for dairy heifersJaylor
Jan Kleinschmidt explains how, in order for heifer rearing programs to be successful, these animals must be given the same time and consideration as the milking herd.
Jaylor: Forage Testing for Producers When, Where and HowJaylor
Many factors (variety, maturity, growing conditions, handling practices, etc.) affect forage quality prior to the time it is fed. As a result, predicting forage quality values from standard books often grossly overestimates or underestimates feeding value.
Not only has gentics and nutrition played a major role in maximizing milk production, but farm management, labor, and facilities all play a role as well. Jaylor's Ruminant Nutritionist, Janet Kleinschmidt, discusses how in PART 2 of this presentation.
Anwendung des "Business Model Canvas" (Geschäftsmodell-Rahmen) anhand des "Verrückte Kuh"-Beispiels. Hier sind einmal ein paar wenige Ideen für neue Geschäftsmodelle gegenübergestellt, um zu verdeutlichen, wie neue Geschäftsmodelle mit dem BMC "designed" werden können.

4. Mechanism of Luteolysis in Cattle 1956Hysterectomy was shown to extend luteal lifespan in cattle (Wiltbank and Casida, J AnimSci 15:134-140)
5. 1967– Removal of the uterine horn ipsilateral to the CL prevented luteal regression, whereas regression occurred normally when the uterine horn contralateral to the CL was removed (Ginther et al., J ReprodFertil 14:225-229)
6. Conclusions: 1) The luteolytic substance originates from the uterus 2) Luteolysis is a local rather than a systemic process
