چکیده
FIN is an initiative ot the Grain and Feed Trade Association, funded by the Sea Fish Industry Authority Today's dairy farmer faces many challenges. Depressed milk prices focused attention on the need to improve productivity, reduce input costs and add value to milk output. At the same time, milk processors and consumers are stepping up their demands for assurances of safe, healthy products – produced with care for animal welfare and the environment.

Performance of dairy cows offered isonitrogenous diets containing urea or fishmeal in early and in mid-lactation.
Sixteen Friesian cows were used in Expt 1 to measure the effect of substituting urea-N with fishmeal-N either in early lactation (Part 1) or in mid-lactation (Part 2). In Part 1 (days 15-84 of lactation) the major N constituent of the concentrate was urea (U), urea-N: fishmeal-N in the ratio 2:1 (UF) or 1:2 (FU), or fishmeal (F). In Part 2 (days 84-175 of lactation) only urea (UM) and fishmeal ...
متن کاملThe effect of concentrate supplements differing in ruminal protein degradability on milk production and blood metabolite concentrations of dairy cows grazing perennial ryegrass pasture
An experiment was carried out to compare the milk production of Friesian cows grazing perennial ryegrass pastures when fed an energy supplement or supplements with high levels of undegradable protein. Eighty-seven cows were blocked on the basis of calving date and milk yield and allocated to one of three treatments. The treatments consisted of 1.25 kg/day of concentrates based predominantly on ...
متن کاملEffect of mechanical processing and fat removal on the nutritive value of cottonseed for lactating dairy cows.
In experiment 1, 24 midlactation, multiparous Holstein cows were used in six 4 x 4 Latin squares to evaluate extruded-expelled cottonseed (EEC) as a source of ruminally undegradable protein (RUP). Diets were formulated to contain: 16% crude protein (CP), 35% RUP (SBM16); 18% CP, 35% RUP (SBM18); 16% CP, 40% RUP using EEC (EC16); and 16% CP, 40% RUP using a fishmeal-blood meal blend (FBM16). Mil...
متن کاملPerformance of lactating dairy cows fed alfalfa or red clover silage as the sole forage.
Three Latin square trials, with 20 (two trials) or 24 (one trial) multiparous lactating Holstein cows (four in each trial with ruminal cannulae), compared the feeding value of red clover and alfalfa silages harvested over 3 yr. Overall, the forages contained similar amounts of neutral detergent fiber and acid detergent fiber; however, red clover silage contained more hemicellulose, less ash and...
متن کاملThe amino acid composition of protein feedstuffs before and after ruminal incubation and after subsequent passage through the intestines of dairy cows.
The amino (AA) profile of eight feedstuffs (two samples of fishmeal, soybean meal [SBM], formaldehyde-treated SBM, sopralin, cotton-seed meal [CSM], rapeseed meal [RSM], corn distillers grains [CDG], and corn gluten feed [CGF]) was determined before and after ruminal incubation for 8 and 12 h in three lactating Friesian cows using nylon bags. The profile of AA disappearing during intestinal pas...
