“…Despite of higher DM and ME intake on treatments A and D, feed efficiency was even better compared to restricted treatments during the early part of the growing period similarly as in the experiment of Moloney et al (2008). Restricted DMI only during the late part of the growing period may even impair feed efficiency, as was the case in the present experiment and also in the experiment of Moloney et al (2008).…”

“…Decreased carcass fatness is also a general expectation of the compensatory growth phenomenon (Carstens et al 1991, Wright and Russel 1991, Carstens 1995, Keogh et al 2015, but this effect was not found in the present experiment. According to earlier experiments, these effects vary (Tudor et al 1980, Abdalla et al 1988, Hornick et al 2000, Moloney et al 2008). The conflicting results may originate partly from differences in severity and duration of the growth restriction, duration of refeeding and genetic background of the animals (Hornick et al 2000).…”

The objective of this study was to determine the effects of restricted feeding strategies on performance of growing and finishing dairy bulls. The feeding experiment comprised in total 32 Finnish Ayrshire bulls with an initial mean live weight (LW) of 122 kg and age of 114 days. Feeding treatments were silage ad libitum and daily barley allowance of 93 g dry matter kg -1 LW 0.60 (A); restricted feeding (R) at 0.80 × A; increasing feeding (I) similar to R until LW of 430 kg and thereafter similar to A; and decreasing feeding (D) similar to A until LW of 430 kg and thereafter similar to R. Restricted feeding strategies decreased daily dry matter intake and LW gain and increased the time to reach the target carcass weight (300 kg). Bulls on I exhibited compensatory growth. There were no significant differences in dry matter or energy efficiency between the treatments. The present experiment indicates that silage intake ad libitum and supplemented with concentrate resulted in most effective beef production.

“…These values suggest that there was no increased stress before slaughter, because the acidification of the muscle occurred as expected. Similar values of lightness, chroma and hue angle were reported by Albertí et al (2014) in young bulls of the Pirenaica breed fed a concentrate diet, and the chemical composition of LT muscle was close to the values reported by Moloney et al (2008) when Charolais × Friesian steers were fed a 60:40 concentrate to forage diet. The WBSF values recorded in LT muscle in both treatments (41.8 N, on average) were below the threshold of 58.9 N proposed by Shackelford et al (1997) to differentiate between tender and tough meat.…”

Eighteen Simmental heifers were fed concentrate and barley straw offered as a total mixed ration (TMR) or separately as a free choice (FCH) to compare performance, behaviour, and meat quality. The heifers were assigned to treatments in a randomized complete block design. Animals were allotted to roofed pens with 3 animals per pen, and 3 pens per treatment. Intake of concentrate, average daily gain, and gain to feed ratio were not different between diets, being on average 7.6 kg/day, 1.38 kg/day and 0.18 kg/kg, respectively. Straw intake was greater in TMR than in FCH treatment (0.7 vs 0.3 kg/day, respectively; p<0.001). Crude protein intake, neutral detergent fibre intake and water consumption did not differ between treatments. Time spent eating was longer in FCH than in TMR (p=0.001), whereas time spent ruminating and total chewing time were longer (p<0.01) in TMR than in FCH. The number of displacements resulting from competition for feed in the main feeder in TMR treatment tended to be greater than in FCH treatment. There were no differences in the carcass characteristics and quality of meat of animals assigned to the different feeding methods, but the percentage of 18:2 n-6 was higher in FCH treatment. In summary, these results suggest that the use of TMR as a feeding method in beef cattle fed high concentrate diets did not affect performance and increased time spent ruminating with a potential decrease of ruminal acidosis incidence.Additional key words: beef cattle; feeding method; high concentrate diets.

“…In addition, Nuernberg et al (2005) found that animals that had been finished on forage and grass exhibited significantly lower L* than did those finished on concentrate. However, there is some controversy over the causes of the colour variation between seasons or finishing diet, and over the pigment mobilization after grazing (Moloney et al, 2008). In this sense, the estimate of fat carotenoid pigment content (SUM) was lower in the INT group (197.7) than it was in the EXT group (215.9) and, as others have suggested, it could be used as a traceability parameter of grass feeding .…”

“…Although the effects of forage-and grain-based feeding systems on beef have been investigated for more than 40 years, (Muir et al, 1998a;Moloney et al, 2008) usually these production systems (INT v. EXT or concentrate v. forage) have been evaluated during the finishing period. Very few studies have assessed the effects of production systems before the finishing period, even though production systems are varied and complex, including mainly the influence of the origin of the animals, age at weaning, diet and management before the fattening period.…”

Twenty Gascon young bulls that had been reared either in intensive conditions (INT) (n = 10) with early weaning at 3 to 4 months, or in a traditional extensive (EXT) system (n = 10) with weaning at 7 months, were subjected to the same conditions during the 145-day finishing period. Production system before the finishing period did not affect conformation, dressing percentage or morphology of the carcass; nevertheless, tissue composition differed somewhat between the two groups. Display had a stronger effect on meat colour than did production system. Percentage of myoglobin was highest in INT (P ⩽ 0.001), although meat texture and sensory quality did not differ between rearing conditions. EXT animals had darker, more yellow fat, a higher percentage of n-3 fatty acids (P ⩽ 0.001), a lower percentage of saturated fatty acids (P ⩽ 0.05) and a lower n-6/n-3 index (P ⩽ 0.001) than did the INT-reared animals. Production system before the fattening period might modify some of the characteristics of commercial beef, especially those associated with fat.Keywords: Gascon breed, beef cattle, colour, panel test, fatty acids ImplicationsThe effect of background before the entrance in a feedlot on meat quality in beef has been hardly studied for the literature available on this topic is very scarce, especially when the productive life of the animals is considered as a whole and animals are fed a common finishing diet. Our results show new information and complement the existent helping to understand the possible influence of the previous fattening production system, as grazing at an early stage provokes certain distinctive characteristics that are kept even after several months of concentrate feeding.
