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...

Control of milk composition is of importance in dairy ewes because milk is mostly used for cheese making. Besides numerous factors that alter milk composition, knowledge on the effects of nutrition is useful for it concerns both yield and milk content. Furthermore, modification of nutrition is a powerful and short-term means of altering milk composition. Global effects of nutrition are to be se...

stats are a family of latent transcription factors that reside in the cytoplasm of resting cells. the stat1 transcription factor gene located on the chromosome 2 at interval 60 to 63 cm. this factor upon stimulation with inf gamma, dimerizes and translocate to the nucleus where mediates transcriptional regulation. in this study, we estimated the allele and genotype frequencies of stat1/pag1 gen...

the objective of this study was to determine the effects of feeding different levels of monensin on feed intake, milk production and composition, and milk fattyacid profile in lactating holstein cows. four multiparous cows averaging 517 ± 47 (sd) kg in body weight and 101 ± 19.8 (sd) days in milk were housed individually in tie-stalls. the study was conducted as a 4 × 4 latin square design for ...

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...

seasonal variation of fatty acids composition of milk and various milk products have been subjected to many investigations.however ,most of the researches are concerned with a single product and apparantly there is no inforation about the extent and the factors which contribute to changes in fatty acids composition of lipids in the process of ghee-making by the  traditional methods.thus compara...

1. In mammals, nutrient allocation during lactation is a critical component of maternal care as milk intake promotes juvenile growth and survival, and hence maternal and offspring fitness. 2. Milk composition varies widely across mammals and is hypothesized to have arisen via selection pressures associated with environment, diet and life history. These hypotheses have been proposed based on obs...

A variety of proteins contributes greatly to the unique nutritional and functional quality of dairy cow milk. Particularly, milk casein content and composition have substantial influence on the processing capabilities. In the present study, milk of 23 multiparous Holstein-Friesian cows, grouped as high(3.49 ± 0.05%; n = 11) and low-protein (3.03 ± 0.05%; n = 12) cows, was sampled approximately ...
