Objective Our objective was to evaluate fasting heat production in cattle with and without the GDF8 mutation. Materials and Methods The heifers used in this study were genotyped for the myostatin(MSTN) gene mutation to determine their MSTN genotype a

Although the inclusion of fat has reduced methane production in ruminants, relatively little research has been conducted comparing the effects of source and profile of fatty acids on methane production in lactating dairy cows. A study using 8 multipa

The addition of fat and calcium sulfate to diets fed to ruminants has resulted in a reduction in methane production, but the effects on energy balance have not been studied. A study using indirect calorimetry and 16 multiparous (8 Holstein and 8 Jers

Feeding fat to lactating dairy cows may reduce methane production. Relative to cellulose, fermentation of hemicellulose is believed to result in less methane; however, these factors have not been studied simultaneously. Eight multiparous, lactating J

Calcium, P, Mg, K, and S retention in carcass, offal, and viscera were measured in 2 beef cattle experiments. Experiment 1 used 30 steers (245 kg of BW; SE = 4 kg) wintered at 3 levels of gain: grazing wheat pasture at a (1) high or (2) low rate of g

Drylot beef cow-calf systems are viable alternative management systems to traditional forage-based systems. In such confinement, adding ionophores such as monensin to the diets of beef cattle is common, and has been shown to improve feed efficiency a

Shortening the period of recording individual feed intake may improve selection response for feed efficiency by increasing the number of cattle that can be recorded given facilities of fixed capacity. Individual DMI and ADG records of 3,462 steers an

Two experiments were conducted to study the effects of monensin dose on growth performance and O157:H7 shedding in finishing beef cattle. In Exp. 1, 198 heifers (298 ± 1.1 kg BW) were allocated to 1 of 2 treatments consisting of 1) 200 mg/heifer dai

An indirect calorimetry experiment was conducted to determine the effects of feeding zilpaterol hydrochloride (ZH) for 20 d on total body oxygen consumption, respiratory quotient, methane production, and blood metabolites in finishing beef steers. Si
