Increasing the total lipid concentration and modifying the fatty acid profile in forage may increase energy intake and productivity of animals and improve the attributes of meat and milk for human health. To predict the outcome of modifying these traits in ryegrass, 3 groups of weaned lambs (n=15 per treatment) grazed ryegrass (4% total lipid) and received twice-daily oral doses of oil at 0, 28...

Reproduction incurs a high energetic cost and failure to meet nutritional needs results in reproductive failure. In red deer hinds, the interaction between nutrition, summer lactation and subsequent ovulation/conception is of particular interest for farmed deer production in NZ due to climatic constraints to summer pasture production in many areas. However, few studies have focussed on the pote...

Alfalfa (Medicago sativa L.) may support better stocker calf gains than common bermudagrass [Cynodon dactylis (L.) Pers.] in the southern USA. Yearling heifers (Bos taurus3 B. indicus) grazed each type of pasture for 2 yr on a Coastal Plain soil in southwest Arkansas. Alfalfa stand counts declined linearly with time after planting. Spring forage mass was greater for alfalfa than bermudagrass, b...

Pig breeding is one of the leading agricultural sectors that ensures country’s food safety. In this regard, pig must become a highly profitable branch agro-industrial complex due to growth range production performance indicators. Various feed additives are reserve for increasing productivity animals. The most popular supplements used today probiotics and phytobiotics. Modern probiotic preparati...

BACKGROUND An experiment was conducted in Vietnam to test the hypothesis that total dry matter (DM) intake and liveweight (LW) gain would increase in a curvilinear manner with increasing amounts of concentrate offered. METHOD There were five treatments: a basal diet of Guinea grass fed at 1 % of LW and rice straw fed ad libitum (T0), or this diet supplemented with concentrate at 0.6 (T1), 1.2...
