Daily Gain

Growth, efficiency and carcass traits were evaluated for goats fed barley or a concentrate mix (CM). Goats on the CM showed higher (P < 0.01) average daily gain (ADG) (27.5%), end of test weight (11.6%), hot carcass weight (HCW) (14.9%) and rib-eye area (REA) (14.7%), lower (P < 0.02) concentrate to gain ratio (CG) ratio (22.5%) and no differences (P > 0.05) in concentrate intake (CI) and dressing percent (DP), compared to those on barley. Although feeding the CM improved ADG, CG, HCW and REA, it may be relatively more economical to finish goats on whole barley grain. Key words: Goat, high energy, high protein, growth, rib-eye area

Feeding added protein to large frame steers increased average daily gain (ADG) and intake but had no effect on dry matter:gain, carcass weight and carcass quality. Including 2% added fat had no effect on ADG and carcass traits. However, feeding 4% added fat increased ADG to 56 d, although ADG overall and carcass quality were not influenced.

Studies were undertaken to evaluate bloodless castration (B) based on growth and carcass traits. During the first 28 d, bloodless and surgical (S) castrates showed a 51–53% and 68–73% reduction in average daily gain, respectively, compared with intact bulls (I) (P < 0.05) in two trials. Bulls grew faster than steers overall. Carcass traits and grade were similar for B, S and I (P > 0.05). Key words: Bloodless, surgical, castration, growth, carcass traits

Two-hundred and nine purebred Yorkshire newly weaned piglets were used to determine the effect of the sweetener Stevia (Stevia rebaudiana) at 83.3, 167 or 334 mg kg−1 diet on feed consumption (FC), average daily gain (ADG) and feed to gain ratio (F/G) compared with treatments with 5% sucrose and no sweetener (control; C). The Stevia-containing diets did not appear to have detrimental effects on the FC and F/G ratios of the piglets when compared with C. The results indicated only a limited potential for Stevia as feed additive for piglets. Key words: Sweetener, palatability, Stevia, weaned pigs

A total of 120 steers were fed either barley silage (BS) or triticale silage (TS) combined with barley (B) or high-moisture barley (HMB) grain, as a total mixed ration in a 2 × 2 factorial design with three replications. The barley and triticale yields were 9.8 and 8.7 t ha−1, respectively. No differences (P > 0.05) in weight, average daily gain, dry matter intake or feed efficiency were observed for treatments or interactions. TS can be used to replace BS at moderate levels in growing steer rations containing barley grain. Key words: Barley, triticale, silage, steers, performance

Two trials were conducted to determine the crude protein (CP) requirements of large-frame (LF) cattle managed under two regimes and fed one of two energy levels. Trial 1 involved 216 recently weaned LF calves, while trial 2 involved 192 LF backgrounded yearling steers. In each trial, the cattle were fed diets formulated to one of two energy levels (11.17 and 11.88 MJ ME kg−1 DM) and one of six CP levels (11, 13, 15, 16, 17 and 19% DM basis). High-energy feeding increased (P < 0.05), average daily gain (ADG), average daily carcass gain (ADCG) and average daily fat gain (ADFG) of weaned calves but did not influence the performance of the backgrounded yearlings. Weaned calves fed 16, 17 or 19% CP had higher (P < 0.05) ADG than those fed 11%, while those fed 16% CP exhibited increased (P < 0.05) ADFG. ADG and ADCG of weaned calves and backgrounded yearlings and ADFG of weaned calves fed low-energy diets increased (P < 0.05) linearly with increasing dietary CP concentration. Daily carcass lean gain of weaned calves fed low-energy diets decreased in a quadratic manner (P < 0.05) as dietary CP level increased. No influence of dietary CP concentration was observed on carcass tissue gain of the backgrounded yearlings. It was concluded that energy balance of animals fed low-energy diets improved with CP supplementation and that current NAS-NRC (1984) CP requirements accurately predict performance of LF cattle.

Thirty-two cull cows aged from 1 to 13 yr were allocated to five age groups and fed individually for 82 days, then slaughtered. Half of the cows within each group were implanted with 36 mg of zeranol. Zeranol had no significant effect on average daily gain, feed efficiency or backfat thickness, but caused a decrease in radio-ulna mass (P = 0.10) and length (P = 0.03). Rate of bone growth at the distal end of the radio-ulna decreased with increasing age to 0 at 4–5 yr. Key words: Cattle, bone growth, zeranol, cull cows, feedlot performance, carcass traits

SUMMARY The objective of this study was to evaluate the effect of probiotic consortium on feed intake, feeding behavior, feed efficiency, fecal score, weight gain and carcass traits in finishing Nellore heifers fed high energy diets in feedlot. Twenty-four Nellore heifers were distributed in 12 pens with two animals each, being six pens per treatment. In the control treatment (CON) the animals were fed exclusively with the base diet, which contained 35% corn silage and 65% concentrate. In the treatment with probiotic consortium technology (TCP), the animals received the base diet and a single dose of 75 mL/animal/day of Bio Ciclo Completo (Global Saúde Brasil) top-dressed in the morning feeding. There was no period of adaptation to the diet. The experiment lasted 93 days. The use of TCP did not affect (P = 0.980) the dry matter intake. The average daily gain was 12.5% greater (P = 0.025) in the animals treated with TCP (0.941 kg/day for TCP versus 0.834 kg/day for CON). The animals that received TCP improved (P = 0.021) the feed efficiency by 12.6%. The animals that received TCP tended to have a better (P = 0.094) fecal score within the first 27 days of feedlot. There were no significant effects of TCP on the feeding behavior and carcass traits. Based on the results, there is a great potential of using TCP to improve productivity in beef cattle.

The present study investigated the effect of gnawing sticks as environmental enhancers on the performance, carcass traits and behaviour of individually housed growing rabbits. Two batches of weaned New Zealand White (NZW) rabbits were used, each consisting of 135 animals. Rabbits were homogeneously classified into the following three groups, each consisting of 45 rabbits: rabbits housed individually in cages without enrichment (control), rabbits housed individually in cages enriched with wooden sticks from apple tree and rabbits housed individually in cages enriched with wooden sticks from willow tree. Rabbits reared in enriched cages with apple or willow sticks showed a significantly (P &lt; 0.0001) better performance (live bodyweight at slaughter 2526 and 2591 g, total weight gain 1620 and 1683 g, average daily gain 21.04 and 21.87 g and daily feed intake 78.57 and 74.89 g respectively), and had a higher carcass weight (1648.39 and 1750.26 g respectively, P &lt; 0.0001) than did the control group. Rabbits in apple-stick group had a higher daily feed intake (78.57 g, P &lt; 0.0001) and lower carcass weight (1648.39 g, P &lt; 0.0001) than did those in the willow-stick group. The cortisol concentration was significantly (P &lt; 0.0001) lower in apple and willow groups (9.44 ± 0.02 and 9.35 ± 0.02 nmol/L respectively) than in the control group (17.24 ± 0.03 nmol/L). Moreover, cage enrichment with apple or willow sticks improved the duration of feeding (7.08 and 7.39 min/3 h respectively, P &lt; 0.0001) and drinking (2.54 and 2.67 min/3 h respectively, P &lt; 0.0001) time, and reduced abnormal behaviour (biting the bars of the cage 0.24 and 0.34 min/3 h respectively, P = 0.001) when compared with the control group. Overall, the current results indicated that cage enrichment (with wooden sticks from apple or willow trees for gnawing) increased the final bodyweight and some carcass traits, reduced abnormal behaviour and potentially improved rabbit welfare during intensive rabbit breeding.

Thirty-two double-muscled Belgian White-blue bulls, within a liveweight range of 542 (± 37) to 722 (± 31) kg, daily received 0 or 60 μg cimaterol kg−1 liveweight in a corn silage diet for 136 (± 29) d. Cimaterol slightly improved average daily gain from 1.28 to 1.38 kg (P > 0.05). Cold carcass weight and dressing were increased by cimaterol from 497.0 to 514.6 kg (P < 0.05) and from 71.0 to 72.9% (P < 0.001), respectively. Even in extremely meaty animals, cimaterol exerted a significant repartitioning effect towards more meat and less fat, both in the carcass and in the longissimus thoracis muscle. Cimaterol increased the shear force value from 37.1 to 52.7 N (P < 0.001) but had no effect on other organoleptical traits. Key words: Cimaterol, double-muscled bulls, growth, carcass, meat quality
