“…However, while these high-value cuts are a small percentage of the carcass lean meat yield, they account for a large proportion of carcass value. Therefore, Craigie et al (2012) concluded that there is a clear need for an accurate commercial measurement or prediction methods for true value of the carcasses which is supported also by the present data.…”

“…However, in terms of valuable cuts there were only limited differences between dairy, dairy × Ab and dairy × Hf heifers. Studies summarized by Craigie et al (2012) indicated that the percentage of variation in carcass lean meat yield explained by the EUROP grid was much greater using the entire carcass (R 2 range 0.55-0.75) than using high-value cuts only (R 2 range 0.28-0.57). However, while these high-value cuts are a small percentage of the carcass lean meat yield, they account for a large proportion of carcass value.…”

Adding nitrate to the diet or increasing the concentration of dietary lipid are effective strategies for reducing enteric methane emissions. This study investigated their effect on health and performance of finishing beef cattle. The experiment was a two × two × three factorial design comprising two breeds (CHX, crossbred Charolais; LU, Luing); two basal diets consisting of (g/kg dry matter (DM), forage to concentrate ratios) 520 : 480 (Mixed) or 84 : 916 (Concentrate); and three treatments: (i) control with rapeseed meal as the main protein source replaced with either (ii) calcium nitrate (18 g nitrate/kg diet DM) or (iii) rapeseed cake (RSC, increasing acid hydrolysed ether extract from 25 to 48 g/kg diet DM). Steers (n = 84) were allocated to each of the six basal diet × treatments in equal numbers of each breed with feed offered ad libitum. Blood methaemoglobin (MetHb) concentrations (marker for nitrate poisoning) were monitored throughout the study in steers receiving nitrate. After dietary adaptation over 28 days, individual animal intake, performance and feed efficiency were recorded for a test period of 56 days. Blood MetHb concentrations were low and similar up to 14 g nitrate/kg diet DM but increased when nitrate increased to 18 g nitrate/kg diet DM ( P < 0.001). An interaction between basal diet and day ( P < 0.001) indicated that MetHb% was consistently greater in Concentrate -than Mixed-fed steers at 18 g nitrate/kg diet DM. Maximum individual MetHb% was 15.4% (of total Hb), which is lower than considered clinically significant (30%). MetHb concentrations for individual steers remained consistent across time. Concentrate-fed steers were more efficient (lower residual feed intake (RFI) values) than Mixed-fed steers ( P < 0.01), with lower dry matter intake (DMI) (kg/day) ( P < 0.001) and similar average daily gain (ADG). CHX steers were more efficient (lower RFI; P < 0.01) than LU steers with greater ADG ( P < 0.01), lower DMI (/kg BW; P < 0.01) and lower fat depth ( P < 0.001). ADG, BW or DMI did not differ across dietary treatments ( P > 0.05). Neither basal diet nor treatment affected carcass quality ( P > 0.05), but CHX steers achieved a greater killing out proportion ( P < 0.001) than LU steers. Thus, adding nitrate to the diet or increasing the level of dietary lipid through the use of cold-pressed RSC, did not adversely affect health or performance of finishing beef steers when used within the diets studied.

“…A fast, accurate, minimally invasive method that requires little input is considered the ideal for providing information about the animal (Mitchell et al, 2003). Methods currently used in nutrition research include linear body measurements (Maiwashe et al, 2002;Riva et al, 2004), ultrasonography for measuring backfat, muscle depth, and loin eye area (Liu and Stouffer, 1995;Oviedo-Rondón et al, 2007;Case et al, 2012), total body electrical conductivity (Berg et al, 1994;Dänicke et al, 2001;Fortun-Lamothe et al, 2002), video image analysis (McClure et al, 2003;Mollah et al, 2010;Craigie et al, 2012), dual-energy x-ray absorptiometry (DXA; Mitchell et al, 1997a;Marcoux et al, 2003; R.

Use of dual-energy x-ray absorptiometry in non-ruminant nutrition research

-Precise body composition measurements are essential in animal nutrition studies because the impact of treatments is evaluated based on changes in body weight and composition. Various indirect techniques for animal compositional evaluation have been developed and evaluated for applicability in animal nutrition studies. A fast, accurate, minimally invasive method that requires little input is considered the ideal for providing information about the animal. Measurements obtained by dual-energy x-ray absorptiometry (DXA) are highly correlated with those obtained by chemical analysis and dissection. The algorithms of DXA software partition the six chemical components of the body (lipids, water, proteins, carbohydrates, non-bone mineral, and bone mineral) into three compartments (total body mineral content, fat mass, and lean mass). Questions have been raised about how this partitioning affects the precision of the DXA method. In addition, the relationship between the DXA measurements and dissected carcass tissues is nonrepresentational of the relationship between DXA and chemical analysis. Furthermore, since DXA devices and their software were developed primarily for human medicine, they may not be fully adequate for animal evaluation. Calibration is required to obtain true values. The DXA method has some advantages and disadvantages that should be identified and controlled before calibration. Nonetheless, DXA is a valuable tool that provides precise, repeatable body composition measurements of live monogastric animals and their carcasses.
