We attempted an oral rush desensitization with mixed cow and sheep milk in a 6-year-old boy who had had adverse reactions to cow and goat milks. Skin prick tests and specific immunoglobulin (Ig) E to cow, sheep and goat milks were positive. The double-blind, placebo-controlled food challenge with cow milk was positive too. He underwent a 12-day sublingual-oral desensitization treatment with mix...

I would like to take poetic license and change the title of this presentation to Search for the Elusive Optimum Cow because she is indeed an elusive beast. I have searched for her for over 20 years. I have not yet found her, but I believe I am getting close. During this search, I have heard her defined in numerous ways: the high performance cow, the mini-care cow, the lowmaintenance cow, and th...

To implement precision feeding for dairy cow, an intelligent multiconcentrates feeding system was developed. The system consists of two parts, one is precision ingredients control subsystem, the other is multi-concentrates discharge subsystem. The former controls the latter with 4 stepper motors. The precision ingredients control subsystem was designed based on Samsung S3C2440 ARM9 microprocess...

Johne's disease ('paratuberculosis') is a chronic, infectious, wasting disease that affects dairy cattle. Estimation of its impact on herd productivity and corresponding economic loss on US dairy operations was part of the USDA National Animal Health Monitoring System's (NAHMS) 1996 national dairy study. Johne's-positive herds experience an economic loss of almost US$ 100 per cow when compared ...

Involuntary culling (IC) is where a cow is disposed of due to injury, poor health or infertility. The main reasons for IC are infertility, mastitis and lameness. These reasons have differing age profiles in when they affect cows, cost variable amounts to treat and have an effect on the value of the cow at market. They also reduce cow welfare in different ways. These factors influence the econom...

The major aim of this study was to compare the morphology and activity of rumen protozoa of Khuzestan water buffalo and Holstein cow using in vitro digestibility and gas production parameters of steam treated sugarcane pith. Rumen fluid obtained from two buffalo and cow steers fed the same diet, 30:70 concentrate: forage. To separate rumen protozoa, antibiotic solution and fungicides w...

Maternal performance of 134 Hereford (H), Brangus (B), and reciprocal crossbred (H x B and B x H) cows from 2 to 7 yr of age was evaluated under semidesert conditions in this study. Calves produced by 2- and 3-yr-old cows were sired by Brangus and Hereford bulls. Calves produced by 4- to 7-yr-old cows were sired by Charolais bulls. Breed of sire and breed of dam of cow affected kilograms of wea...

A study was conducted to evaluate the effect of sire growth potential, steer age, and cow size on intake, growth, and production efficiency in grazing cattle. Data were collected on 24 cow-calf pairs during each of four summers (1989 to 1992) and on 12, 7-mo-old and 12 yearling steers during three summers (1990 to 1992). Suckling calves and older steers were sired by either high-(Charolais with...

For millennia, cow has been central to Indian economy, life and culture. There are innumerable references-Vedic and subsequent to the sacred significance of cow. The benefits of cow have been described at length in relation to agriculture, environment, health, economy and spiritual progress. However, the socio-political issues surrounding cow as a sacred animal have raised acrimonious debates. ...
