Carryover effects of feeding soybean hulls (SBH) on toxic tall fescue [Schedonorus arundinaceus (Schreb.)] pasture and effects of postgraze steroid implantation on performance and physiology of steers were evaluated in a 2-yr experiment. Following grazing, 36 steers were assigned to 9 pens, and pens were randomly assigned 3 to the following pasture-pen combinations: 1) feeding SBH on pasture an...

In a first experiment, 2 groups of 46 and 47 multiparous ewes received diets which provided an iodine intake of 0.36 and 0.26 mg/kg dry matter (group C) and, 2.01 and 1.94 mg/kg (group D), respectively, for pregnancy and lactation. In a second experiment, 3 groups of 10 nulliparous ewes received diets which provided an I intake of 0.13 and 0.12 mg/kg dry matter (group A), 0.22 and 0.20 mg/kg dr...

Methane emissions in ruminants are influenced by various factors, including feed type and rumen microbial population. Mitigation strategies involve nutritional interventions, soil plant management, synergistic use of different forages. Effective management practices pasture-based systems, such as monitoring forage mass adjusting stocking rates, optimize intake quality, resulting reduced improve...

To investigate the extent to which enteric methane (CH4) emissions from growing lambs are explained by simple body weight and diet characteristics, a 2 × 2 Latin square changeover design experiment was carried out using two sheep breeds and two fresh pasture types. Weaned lambs of two contrasting breed types were used: Welsh Mountain (WM, a small, hardy hill breed) and Welsh Mule × Texel (TexX,...

Trials were started in spring, summer and autumn to compare the effect of Agrotain-treated urea and standard urea, at application rates of 25, 50, 75 and 100 kg N/ha, on dairy pasture production on a commercial dairy farm in Canterbury. There were six replicates of these eight treatments, plus two control plots per replicate where no urea was applied. Each trial was mown three times at around t...

Background: Fat supplementation in ruminants ration often adversely affect dry matter intake (DMI), rumen fermentation and nutrients digestion. Basal diet ingredients is an undeniable determinant of ruminants responses including performance, chewing behaviour and nutrient digestibility to fat supplementation. Objective: Current study was conducted to evaluate the effect of Fish oil (FO) supplem...
