The authors have analysed fat contents and fatty acid composition of the mother’s colostrum and mother’s milk in comparison with the newest publications. They have established that the average fat contents of the mother’s milk were 3.6–4.0%, and increased during lactation. Among the different ethnic groups there was found no significant difference in the fat contents of the mother’s milk, altho...

this study was conducted to evaluate production response of early lactating cows to rumen protected fats. twelve (nine multiparous and three primiparous) holstein cows (26±4 d in milk) were empolyed in a replicated 3×3 latin square design of 21-d periods. each period consisted of 14 days of adaptation and 7 days of sampling. cows received diets containing either one of two types of protected fa...

This study was conducted to examine the effects of condensed tannins (CT) from Ficus bengalensis leaves on the feed utilization, milk production and health status of crossbred cows. Eighteen crossbred dairy cows at their second and mid lactation (avg. BW 351.6±10.6 kg) were randomly divided into two groups of nine each in a completely randomized block design and fed two iso-nitrogenous suppleme...

objective: to modify yeild of milk fat and to improve fatty acids profile of milk fat with supplementation of the diet with fish oil enrich in omega-3 fatty acids, especially, eicosapentaenoic acid (epa) and docosahexaenoic acid (dha). design: clinical trial. animals: ten dairy cows (treatment group, n=5 and control group, n=5). procedure: different amounts of fish oil were fed to the treatment...

In lactating mammary glands, milk fat is secreted as fat globules surrounded by a cell plasma membrane containing characteristic membrane-associated proteins. Among these, butyrophilin has been shown to be specific and intrinsic to the fat globule membrane, whereas milk-fat globule EGF-factor VIII (MFG-E8) is uncertain. We characterized in the present study MFG-E8 in milk fat globules and in th...

The objectives of our study were to determine the effects altering dietary ratio palmitic (C16:0) and oleic (cis-9 C18:1) acids on production metabolic responses early-lactation dairy cows during immediate postpartum period evaluate carryover treatment diets early in lactation. Fifty-six multiparous used a randomized complete block design randomly assigned 1 4 treatments (14 per treatment) fed ...

Twenty-eight (8 with ruminal cannulas) lactating Holstein cows were assigned to seven 4 x 4 Latin squares in a 16-wk trial to study the effects on production and ruminal metabolism of feeding differing proportions of rumen-degraded protein (RDP) from soybean meal and urea. Diets contained [dry matter (DM) basis] 40% corn silage, 15% alfalfa silage, 28 to 30% high-moisture corn, plus varying lev...

We evaluated the effect of wet corn gluten feed and a novel product containing raw soybean hulls and corn steep liquor on performance in lactating dairy cows. Forty-six multiparous Holstein cows were used in a randomized incomplete block design. Cows were housed in tie stalls for the first 13 weeks of lactation and moved to group pens for the remainder of the study. Cows were blocked by calving...

Signer, E., Murphy, G. M., Edkins, S., and Anderson, C. M. (1974). Archives of Disease in Childhood, 49, 174. Role of bile salts in fat malabsorption of premature infants. Eighteen premature infants were studied. 9 were fed with human milk and 9 with a modified cow's milk. Subsequent to a 72-hour fat balance, a duodenal intubation was performed on the 14th day of life. Total bile acids were det...

data related to holstein dairy cattle from 1987 to 2004 were obtained from animal breeding center of iran to estimate the genetic and phenotypic trends. variance components and genetic parameters of the first lactation records were estimated using restricted maximum likelihood method and aireml algorithm through matvec program. animal breeding values were predicted through multiple-trait animal...
