Milk performance (protein and fat content) and milk fatty acids (FA) profile of dairy cows under supplementation with two sources of concentrate, oilseeds (C, cottonseed) at two levels, low (5kg DM/cow/day) and high (7 kg DM/cow/day), and cereal grains (B, barley) at high rate (7 kg DM/cow/day), were studied in three herds (n=36) of spring calving Holstein-Friesian dairy cows (200 days in milk)...

Profitability of different grouping criteria was simulated in a dairy farm with 153 lactating cows that were divided into three groups of high (79), medium (40) and low (34) cows based on the milk records. Animals were reassigned to the new groups based on the following criteria using a decision support tool and the same three groups scenario: fat corrected milk 4%, days in milk (DIM), dairy me...

High concentrate diets are fed to early and mid-lactation stages dairy ruminants to meet the energy demands for high milk production in modern milk industry. The present study evaluated the effects of a high concentrate diet on milk fat and milk composition, especially, cis-9, trans-11 CLA content in milk and gene expression of lactating goats. Eight mid-lactating goats with rumen fistula were ...

. eight holstein cows in early lactating stage were used in a 4×4 change-over design within 4 periods of 21-d to determine the effects of alfalfa hay particle size and soybean oil supplementation on intake, digestibility, ruminal and blood metabolites, chewing activity, milk yield and compositions. four total mixed rations containing 20, 20 and 60% corn silage, alfalfa hay and concentrate respe...

A replicated randomized block trial was conducted to determine the response of Holstein cows rotationally grazing annual ryegrass-Crimson clover pasture to supplemental concentrate. Within each of 2 yr, 16 Holstein cows were assigned to one of four blocks by energy-corrected milk yield, days in milk, and parity. Treatments included one of four levels of concentrate based on the following grain ...

current interests towards lowering fat content in food products and producing healthier and safer foods, have convinced ice cream manufacturers to substitute milk fat in ice cream with either carbohydrate or protein based fat replacers. in the present work, reduced-fat ice cream (5% fat) was produced using milk protein concentrate (65%) and inulin as fat replacers (0, 2 and 4%) as well as two t...

This thesis consists of studies concerning the effects of dry period energy feeding, and early lactation energy and protein feeding on the metabolic and hormonal status, tissue mobilisation and lactation performance in dairy cows. In all studies, restricted amounts of grass silage were fed during the dry period, and lead feeding with concentrate was applied during the last three weeks of pregna...

the present study was conducted on efficiency of utilization of dietary energy for milk production in lactating crossbred cattle. 18 lactating crossbred cattle of early to mid-lactation, approximate body weight (375.39±23.43 kg), milk yield, parity and stage of lactation were divided into three groups of six animals each and were fed 0, 50 and 100% diammonium phosphate (dap) in the mineral mixt...

Twenty-four multiparous lactating Holstein cows were blocked by days in milk and assigned to treatment sequences in a replicated 4x4 Latin square with 21-d periods. The four diets, formulated from alfalfa silage plus a concentrate mix based on ground high moisture ear corn, contained [dry matter (DM) basis]: 1) 20% concentrate, 80% alfalfa silage (24% nonfiber carbohydrates; NFC), 2) 35% concen...
