days open survival analysis milk yield
2008/7/25
The associations among milk yield, days open, and days to first breeding were studied in 15,320 Holstein cows, calving between June 1990 and November 1993, in 26 New York herds. Survival analysis, inc...
Textural Properties of Yogurt Made with Encapsulated Nonropy Lactic Cultures
yogurt firmness syneresis
2008/7/25
The effects of encapsulated strains of lactic acid bacteria on the textural properties of yogurt were determined. Yogurt made with encapsulated nonropy single strains of lactobacilli exhibited the low...

2008/7/24
The predominant ruminal bacteria that were obtained from a 108 dilution of ruminal fluid could be maintained as a mixed population for long periods as long as the bacteria were provided with a complex...
The Effect of Bovine Somatotropin and Diet on Somatotropin Binding Sites in Hepatic Tissue of Lactating Dairy Cows
binding sites dairy cows liver somatotropin
2008/7/23
In the lactating cow, galactopoiesis is stimulated by treatment with recombinant bovine somatotropin (bST) and by an improved plane of nutrition. The present study determined the interaction between t...

calf disease growth failure of passive antibody transfer
2008/7/22
Our objective was to study the effects of pneumonia (cumulative incidence, 25%), diarrhea (29%), umbilical infection (14%), and umbilical hernia (15%) on BW and height gains during the first 3 mo of l...
The Effect of Dietary Crude Protein as Protected Soybean Meal on Mammary Metabolism in the Lactating Dairy Cow
protein mammary gland metabolism lactation
2008/7/21
Metabolism in the mammary gland was related to changes in milk output in response to changes in dietary protein intake. Three diets of grass silage and concentrate were fed to four lactating dairy cow...
The Effect of Liposome-Encapsulated Cyprosins on Manchego Cheese Ripening
liposome cyprosins acceleration of ripening Manchego cheese
2008/7/21
Cyprosins, the proteinases present in cardoon rennet, were extracted from dried flowers of cardoon (Cynara cardunculus L.) and encapsulated in dehydration-rehydration liposomes. Liposomes were added t...

2008/7/18
For 3 successive yr, whole-plant corn was ensiled in laboratory silos with low percentages of silage preservatives, the primary active ingredient of which was propionic acid. Preservatives were added ...
The Effect of Recombinant Bovine Placental Lactogen on Induced Lactation in Dairy Heifers
bovine placental lactogen prolactin induced lactation mammogenesis
2008/7/17
The primary objective of this study was to determine whether bovine placental lactogen stimulated additional mammary growth as assessed by milk yield from a lactation induced by steroids. Pubertal, no...
