Effect Of Feeding

Since feed accounts for 75-85% of the variable costs of beef production, the use of alternative feeds and high-energy forages that have a lower cost per unit of energy are worthy of investigation. The technique of harvesting cereals where the whole-crop is harvested at a dry matter (DM) content of 650-750g/kg with the harvester fitted with a grain processor has recently been developed. The objective of this trial was to determine the effect of feeding either adlibitum processed urea treated whole-crop wheat (Alkalage) or cereals on the performance of Continental cross beef cattle since there is no data on the performance of beef cattle fed Alkalage.

Finishing Beef Cattle

In Northern Ireland grass silage is the basal forage for beef cattle during the winter feeding period. Increasingly however, other ensiled forages are being considered due to their potentially lower cost and perceived conservation and nutritional attributes. Wholecrop cereals such as wheat have been shown to improve dry matter (DM) intake but not animal performance (Keady et al, 2007). With increasing volatility in world markets creating major fluctuations in protein prices, interest has increased in home grown protein sources. High protein legumes with low input costs, such as lupins have given reasonable animal performance when offered as a monoculture. However, limited scientific research has been undertaken on the role of legumes in combination with a cereal as a bi-crop for finishing beef cattle. Consequently the objective of the current study was to evaluate the effects of legume/cereal wholecrop offered either alone or in combination with grass silage on the performance of beef cattle.

Effect Of Feeding

There is increasing consumer resistance to feeding antibiotic performance enhancers to beef cattle which has created interest in the use of yeast cultures as an alternative. Yeast cultures such as Diamond V ‘XP’ (Rumenco) are produced by growing selected yeast strains (on a semi-solid medium under stressed conditions) which are then dried. Yeast cultures are now used in a considerable number of North American beef feed lots. The objective of this work was to evaluate the effect of feeding ‘XP’ Yeast to finishing beef cattle on a typical UK grass silage-based diet.

Finishing Beef Cattle

The use of fodder beet as the primary diet for finishing beef cattle is a recent New Zealand innovation. A system using ad libitum grazed fodder beet through autumn and winter to finish spring-born steers between 12 and 18 months old was developed. Fodder beet is a high energy yet comparatively low protein content feed, and the fodder beet system requires high liveweight gains on the crop and an early slaughter age for cost effective production. Lower liveweight weaners have a greater protein requirement for optimal weight gain, and the threshold entry liveweight for satisfactory performance in this feeding system was not yet established. The objective of this study was to quantify the effect of the entry liveweight of weaners on liveweight gain in the fodder beet feeding system. A group of 392 rising 1-year-old beef cattle fed using this system were divided at entry into three groups on unfasted liveweight (kg): A, 290-370; B, 240-260; and the remaining animals. The heaviest (group A: steer n=67, 316 ±2.7 kg; heifer n=45, 312 ±2.5 kg) and lightest (group B: steer n=77, 249 ±0.7 kg; heifer n=19, 251 ±1.0 kg) groups were then treated identically on ad libitum fodder beet to compare liveweight gain across 130 days on crop. The mean liveweight daily gain (kg/ day) for group A was significantly greater than group B, and greater for the steers compared to heifers in group A (0.98 and 0.85), but not in group B (0.82 and 0.81). Mean liveweight gain as a proportion of entry liveweight was greater in group B, and greater in steers. Both mean daily liveweight gain and mean liveweight gain as a proportion of entry liveweight were positively correlated with entry liveweight, but the R2 of both was low (0.14 and 0.05, respectively). Mean daily liveweight gain values of this magnitude are greater than those previously reported for alternative winter crops, and satisfactory for finishing beef cattle in this system. This study suggests the use of beef cattle above 240 kg liveweight as weaners in this fodder beet feeding system, both steers and heifers, is satisfactory for achieving acceptable slaughter liveweight before 18 months old.

Natural Additive

Abstract To improve production without affecting the environment, the objective of this research was to evaluate a natural additive to replace the conventional growth promoters in finishing beef cattle diets. 160 Nellore bulls were assigned into two treatments, where the only difference was the additive used: natural additive (Fator P - 600 mg/kg DM) and conventional growth promoters (25 mg/kg DM of monensin + 20 mg/kg DM of virginiamycin). The Fator P® is an organic additive certificated by IBD, which is a blend of the compounds; amino acids (lysine, methionine, and tyrosine), choline, minerals, probiotics and essential fatty acids (omega 3 and omega 6). The diet contained 14% CP and 76% TDN. Nellore young bulls (n = 160), weighing 433 ± 7 kg, with an average age of 24 months, were used. The feedlot facilities contained 16 collective pens, in which 10 animals were allocated. The animal performance was evaluated for 84 days, with 21 days of adaptation. Means were compared with 5% of significance. The conventional growth promoters reduced the dry matter intake. Natural 11.33 kg/day and 10.9 kg/day for the conventional. The conventional growth promoters reduced in 0.43 kg of dry matter intake (P = 0.042) or 0.1% of body weight (P = 0.001; 2.26% to 2.16%). No difference in average daily gain (P = 0.58). 1.655 kg/day for natural and 1.625 for the conventional. The feed efficiency ratio wasn’t different (P = 0.71), natural 146 g / kgMSˉ¹ and 148 g / kgMSˉ¹ for conventional. There were no difference in carcass yield (P = 0.89), mean 56.3%. The natural additives can improve the dry matter intake and can be used as an alternative to antibiotics in high concentrate diets for beef cattle in feedlot system. Thus, finishing beef cattle in the feedlot can be environmentally friendly.

Different Sources

The aim of the study was to compare the effects of sodium selenite (SS), selenium yeast (SY), and hydroxy-selenomethionine (OH-SeMet) on the meat quality and selenium (Se) deposition of finishing beef cattle. Sixty-three bulls were distributed over 3 treatments and fed SS, SY, or OH-SeMet at 0.2 mg kg−1 dry matter (DM) for 60 d. None of the Se sources affected the growth performance or carcass characteristics. OH-SeMet showed a higher Se transfer to the meat than SS or SY (p < 0.01). SY and OH-SeMet reduced the shear force of the meat (p < 0.0001), improved pH (p < 0.001), and reduced the drip losses (p < 0.001) and the lipid oxidation of the meat (p < 0.001). During 8 d of storage, OH-SeMet showed higher levels of meat lightness (L*) and yellowness (b*) than SS (p < 0.001), while the SY meat showed a higher L* than SS, albeit only on d 6. OH-SeMet improved b*, compared to SS, and also compared to SY on days 4, 7, and 8 (p < 0.001). Supplementing beef with SY and OH-SeMet improved several meat quality parameters. OH-SeMet appears to be the most effective strategy to improve the Se content and color stability of beef cattle meat.

Finishing Beef Cattle

AbstractTwo experiments have been carried out to compare silage-based and dried forage-based diets for finishing beef cattle, and to examine the effect of supplementing the silage-based diet with additional protein. The three diets used in experiment 1 consisted of (1) grass silage supplemented with a low-protein, cereal-based concentrate (98 g crude protein (CP) per kg dry matter (DM)) (2) grass silage supplemented with a high-protein, cereal/soya-bean meal concentrate (208 g CP per kg DM) and (3) grass hay supplemented with a cereal-based concentrate (130 g CP per kg DM). The two diets used in experiment 2 consisted of (1) grass silage supplemented with barley and (2) a mixture of grass hay and artificially dried grass supplemented with barley. All the diets contained approximately 700 g forage and 300 g concentrates per kg DM except diet 3 in experiment 1 which contained 240 g hay and 760 g concentrates per kg. The silages were of high digestibility (digestible organic matter in dry matter 0·72) and were well preserved (ammonia N 36 g/kg total N). The diets were offered to castrated male cattle which were initially 384 kg in experiment 1 and 515 kg in experiment 2. For diets 1 to 3 in experiment 1 and diets 1 and 2 in experiment 2 respectively metabolizable energy intakes were, 92, 94, 94, 124 and 120 MJ/day; live-weight gains were 1·21, 1·16 and 1·21 (s.e. 0·044) and 1·25 and 1·22 (s.e. 0·060) kg/day; carcass gains were 0·76, 0·76 and 0·75 (s.e. 0·034) and 0·80 and 0·74 (s.e. 0·036) kg/day; carcass fat classifications (five-point scale; 1 = leanest, 5 = fattest) were 2·4, 2·9 and 2·2 (s.e. 0·09) and 3·6 and 3·6 (s.e. 0·18); mean subcutaneous fat depths were 6·8, 8·1 and 6·6 (s.e. 0·74) and 7·8 and 7·4 (s.e. 0·48) mm; areas of m. longissimus dorsi at the 10th rib were 66·4, 69·4 and 71·3 (s.e. 3·16) and 77·6 and 72·3 (s.e. 1·52) cm2 and marbling scores (eight-point scale; 1 = leanest, 8 = fattest) for m. longissimus were 1·7, 2·5 and 2·2 (s.e. 0·24) and 3·2 and 2·8 (s.e. 0·16). It is concluded that performance, efficiency of energy utilization and carcass fatness were similar for silage-based and dried forage-based diets, and that protein supplementation of a silage-based diet did not affect performance but tended to increase carcass fatness.
