fourteen primiparous holstein cows (180.0 ± 4.3 days in milk) with a mean (±sd) daily milk yield of 35.0 ± 1.3 kg and a body condition score of 3.2 ± 0.2 were allotted into two groups (n = 7), and were fed a ration consisting of (dry matter basis) 35% corn silage, 25% alfalfa hay and 40% concentrates. salt was provided free choice. the experiment was performed during the period of heat stress, ...

Inclusion of rapeseed feeds in dairy cow diets has the potential to reduce milk fat saturated fatty acid (SFA) and increase cis-monounsaturated fatty acid (cis-MUFA) content, but effectiveness may depend on the form in which the rapeseed is presented. Four mid-lactation Holstein dairy cows were allocated to four maize silage-based dietary treatments according to a 4 × 4 Latin Square design, wit...

Forty midlactation Holstein cows averaging 635 kg of body weight (SE = 8) were allotted at wk 25 of lactation to ten groups of four cows blocked for similar calving dates to determine the effects of formaldehyde treatment of flaxseed and sunflower seed on fatty acid composition of blood and milk, milk yield, feed intake, and apparent digestibility. Cows were fed a total mixed diet based on gras...

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 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...

Brun., 2006, LIV, No. 2, pp. 131–138 Our work deals with a possibility of determination of basic composition (dry matter, fat, protein, casein, lactose and urea nitrogen) of ewe’s milk and colostrum by FT...

The effect of feeding tamarind (Tamarindus indica) seed husk (TSH) as a source of tannin on dry matter intake (DMI), digestibility, N balance, milk yield and milk composition was studied in crossbred dairy cows in mid-lactation. The study included lactation and metabolism trials. The lactation trial was conducted using nine multiparous cows in mid-lactation in a switchback design. The cows were...

1. Studies were conducted to measure the influence of perinatal undernutrition of twin-bearing ewes on ewe milk yields and lamb performance in early lactation. Comparative studies were conducted with lambs to measure the effects of postnatal nutrition on lamb performance and carcass composition. The major objective of this work was to determine the extent of the influence of postnatal nutrition...

The objectives of this research were to (1) determine the feed intake, digestibility, and energy utilization (2) estimate net value cassava chips consumed by lactating dairy cows. Four multiparous Holstein–Friesian crossbred cows at 139 ± 33 (mean SD) day in milk assigned according a 4 × Latin square design with four periods. treatments included diet substituted on 0%, 12%, 24%, 36% dry matter ...
