diacylglycerol acyltransferase1 (dgat1) has been introduced as a strong potential candidate gene for milk fat content in cattle. dgat1 gene plays a key role in the final step of triglyceride synthesis. in this study, the genetic variability in the region spanning exon 1 to exon 2 of the buffalo dgat1 gene was investigated by dna sequencing. two hundred buffaloes belonging to three indigenous po...

in pasture-based milk production systems, using available farm resources in order to reduce feeding costs, the composition and functional properties of dairy cows’ milk are of considerable importance to the dairy farmer, manufacturer and consumer. basically, there are three options for altering the composition and/or functional properties of milk: 1) cow nutrition and grazing management, 2) cow...

the aim of this experiment was evaluating effect of fish oil versus palm oil on mammary gland health and milk production in holstein cows. ten multiparous holstein cows were used from six week before up to 63 days after parturition. feed intake and milk production were recorded daily, milk composition, body weight and body condition score were measured weekly and blood metabolites were determin...

To evaluate the effects of physically processed flaxseed [ground flaxseed (GFS) and whole flaxseed(WFS)] as a replacement for extruded soybeans on feed intake, milk production, milk composition, milk fatty acid (FA) composition and blood biochemical parameters, nine primiparus Holstein dairy lactating cowsaveraging 495 ± 34.5 kg of body weight (BW) and 70 ± 5 days in milk (DIM) were assigned in...

An experiment was conducted in early lactating buffaloes for the period of 3 months in Jadakheria and Polisimal village of LimkhedaTaluka in Dahod district of Gujarat to assess the effect of supplementation of bypass fat on milk production, composition, body weight change and economic efficiency. Forty buffaloes in their 2nd and 3rd lactation were equally divided in completely randomized design...

fifty six holstein lactating cows (71 days in milk; 35 kg/day milk production) were employed in a complete block randomized design of repeated measurements. cows were randomly allocated to two treatments based on their parity. cows in group 1 were fed a balanced total mixed ration (600 g concentrate /kg dm and 400 g forages /kg dm) with 50 g rumen protected methionine (rpm) per head per day (me...

to evaluate the effects of physically processed flaxseed [ground flaxseed (gfs) and whole flaxseed(wfs)] as a replacement for extruded soybeans on feed intake, milk production, milk composition, milk fatty acid (fa) composition and blood biochemical parameters, nine primiparus holstein dairy lactating cowsaveraging 495 ± 34.5 kg of body weight (bw) and 70 ± 5 days in milk (dim) were assigned in...

in this research, in order to describe milk production traits lactation mahabadi goat breed, seven statistical functions were fitted using 1665 milk production traits records and 833 body weight records. the milk production traits were milk yield, fat percent, fat yield, protein percent, protein yield, lactose percent and snf percent. these records have been recorded on 123 goats during years o...

the effects of monesin and propylene glycol on feed intake, milk production, and composition as well as some blood metabolites of 16 primiparous and multiparous holstein lactating cows (60±30 days in milk (dim), milk production of 33±3 kg/day) were evaluated. cows were experimentally in a arranged in a randomized complete block design of: 4 feeding treatments, and 2 blocks of either primiparous...
