An experiment was conducted to determine whether implantation with zeranol would reduce the aggressive behavior and probability of producing dark-cutting carcasses that characterize slaughter bulls. Thirty-six bull calves were allocated to each of four treatments – nonimplanted bulls, steers castrated at an average age of 101 d, bulls implanted with 36 mg zeranol at an average of 101, 170, 263 and 319 d of age and bulls implanted on the latter three dates only. The results reported include observations of weight gains, linear measurements, scrotal circumferences, serum testosterone concentrations, feed consumption, feed efficiency ratios and behavioral traits. Bulls exceeded steers in weight gain during a feedlot test and in body length after 140 d on feed, but neither implantation treatment significantly affected the growth of bulls. Feed consumption and conversion efficiency were lower in steers than in bulls, but were not significantly affected by implantation. Scrotal circumference measurements and serum testosterone concentrations suggested that implantation reduced testicle development during the preweaning and early postweaning periods, but that this effect diminished or disappeared during the later postweaning period. Implantation depressed aggressive and sexual activity between days 111 and 155 of the feedlot test. When evaluated at 13–14 mo of age, both implanted groups reacted to preslaughter mixing of nonfamiliar animals with equivalent head bunting to, but less mounting activity than, nonimplanted bulls. At 15–16 mo of age, however, the implanted bulls exhibited more head bunting than nonimplanted bulls, and the early implanted group exhibited fully equivalent mounting activity to nonimplanted bulls. The dark-cutting carcass condition was associated with mounting activity during preslaughter lairage.

In 1984–1985 and 1985–1986, groups of 136 and 127 male calves were used to assess the effects of multiple implants (Ralgro or Steeroid), castration time (early or late) and castration method (surgical or chemical) on testicular development and weight gain for 28 d following castration. Ralgro-implanted bull calves had smaller scrotal circumference (P < 0.001) and testicle weight (P < 0.001) than nonimplanted calves at early castration (59 ± 1 d), late castration (157 ± 1 d) and at slaughter (459 ± 3 d). Steeroid had no effect on testicle weight at early castration (40 ± 1 d) but reduced testicle weight (P < 0.001) at late castration (148 ± 1 d). Average daily gain (ADG) during the first 7 d postcastration was less for surgically castrated than chemically castrated calves or bulls following early castration (P < 0.05) but in the 7 d following late castration, bull calves grew faster than surgical castrates (P < 0.05) and surgical castrates grew faster than chemical castrates (P < 0.05). The ADG of calves implanted with Ralgro was greater than that of nonimplanted calves during the 28-d period following early and late castration (P < 0.05) but Steeroid had no effect (P > 0.05) on 28-d postcastration ADG. Chemical castration increased scrotal circumference at 7, 14 and 28 d postcastration (P < 0.001) but by day 56, testicular atrophy was complete in those calves that were successfully castrated. Chem-cast was an effective method of castration in young calves (< 90 kg liveweight), particularly those that had been implanted with Ralgro, but efficacy was reduced (P < 0.05) in older calves (> 150 kg liveweight). Key words: Castration, Chem-cast, Ralgro, Steeroid, testosterone, beef

Two trials were conducted to determine feed color effects on broiler performance. A completely randomized design was used. Trial 1 included four treatments: control (complete broiler starter diet), red, green, and blue; and Trial 2 included four treatments: control, orange, yellow, and purple. Each trial had 4 treatments with 4 replicates (60 birds/treatment) fed to 240 male Cobb 500 broilers during a 21 d grow out. Data were analyzed using the GLM procedure. In Trial 1, there were no treatment effects on average body weight, body weight gain, and feed consumption (p > 0.05). Adjusted feed conversion for control (1.23) was less than red (1.27; p = 0.001) and green (1.26; p = 0.009), with blue (1.25; p = 0.056) tending to be different during the experimental period. In Trial 2, there were no treatment effects on average body weight, feed consumption, and adjusted feed conversion during this study (p > 0.05). Body weight gain between d 1 to 14 for purple (490.78 g/bird) was more than orange (467 g/bird; p = 0.013) and yellow (461 g/bird; p= 0.004), with control (474 g/bird; p = 0.052) tending to be different. Results indicate that these feed colors had some, albeit limited, influence on broiler performance parameters.

Penggunaan asam sitrat sintetis nyata dapat menurunkan konversi pakan minggu ke tiga dan empat dibanding kontrol dan asam organik belimbing wuluh. Kesimpulan penelitian ini yaitu penggunaan sari belimbing wuluh sebagai acidifier belum menunjukkan perbaikan performa yang signifikan sedangkan penggunaan asam sitrat sintetis memiliki performa yang lebih baik dibanding perlakuan kontrol dan penggunaan sari belimbing wuluh.Kata kunci: acidifier, asam sitrat, belimbing wuluh, puyuh fase growerABSTRACTThe organic and synthetic acidifiers could improve the optimization of nutrients utilization in the quail digestive tract. Furthermore, the optimization of nutrients is expected to improve quail performance. This study was aimed to determine the effect of using two types of acidifiers (Averrhoa bilimbi juice and synthetic citric acid) on the grower phase of quail performance. Total of 100 unsexed quails (Coturnix coturnix japonica) grower phase aged 14-40 days were used in this research and designed as a completely randomized design of five treatments and four replications. Feed ingredients used were yellow corn, rice bran, commercial quail concentrate, Averrhoa bilimbi juice (organic acidifier), and synthetic citric acid. The treatments consisted of control (P0), 0.3% synthetic citric acid (P1), use of 0.25% Averrhoa bilimbi juice (P2), use of 0.6% synthetic citric acid (P3), and use of 0.5% Averrhoa bilimbi juice (P4). The variables observed were weekly feed intake, body weight gain, and feed conversion. The result showed that utilization of Averrhoa bilimbi juice has lower feed consumption (P<0.05) in the first week compare to control and synthetic citric acid, and synthetic citric acid utilization increases body weight gain in the first week (P<0.05). The use of synthetic citric acid significantly reduces feed conversion in the third and fourth weeks compared to control and organic acid groups. The conclusion of this study is the utilization of Averrhoa bilimbi juice as an acidifier has not shown significant improvements in quail performance. The use of synthetic citric acid has a better performance compared to control and Averrhoa bilimbi juice utilization.Keywords: acidifier, organic acidifier, citric acid, growing quail

EFFECT OF REPLACEMENT OF CORN WITH SORGUM Cv. KAWALI IN PELLET RANSUM ON LOCAL RABBIT PERFORM. The purpose of this study was to determine the effect of substitution corn with sorghum in rabbit rations on feed consumption, body weight gain, and ration conversion. The duration of the study was 28 days using 20 local rabbits. The statistical design used in this study was a completely randomized design, with 4 (four) treatment rations and 5 (five) replications. The four experimental rations, namely R0: 45% corn + 0% sorghum, R1: 30% corn + 15% sorghum, R2 15% corn + 30% sorghum, R3 0% corn + 45% sorghum. Variables were measured, viz: feed consumption, body weight gain and ration conversion. The results showed that the average of feed consumption, body weight gain, and feed conversion, were: 28.27–30.59 g /head /day, 15.76–21.55 g / head /day, and 1.42-1.80 g /head /day, respectively. Based on the analysis of variance, the treatments ration had no significant effect (P> 0.05) on consumption, but had a very significant effect (P <0.01) on body weight gain and feed conversion. The LSD test showed that all treatment rations using sorghum (R1, R2, and R3) gave results of body weight gain which were very significantly different (P <0.01) and higher than R0. Whereas, on ration conversion, treatments R1, R2, and R3 give very different results (P <0.01) lower than R0. It is concluded that the substitution of corn with sorghum at the level of 45% in the ration gives the highest results for body weight gain and conversion of rations for rabbits. Keywords: corn, sorghum, ration, performance, local rabbit

Selection For

Increasing breast muscle percentage by selection for breast layer thickness (muscle and skin) of living ducks by needle probe improves carcass quality as could be demonstrated by experiments and by applied breeding programs. In addition direct selection for individual feed conversion ratio can increase the efficiency of duck meat production. Divergent selection for feed conversion ratio from the age of 4 - 7 weeks over 11 generations has differentiated the feed efficiency by about 25 %. Causes for the reduction in feed conversion ratio are lower fat content of carcass, lower locomotor activity, higher enzymatic activity (alkaline phosphatase and creatinkinase in blood plasma) and better feed protein utilization. Because of lower feed consumption in the line selected for lower feed conversion ratio the emission of nitrogen and phosphorus via manure was reduced by about 39 and 26 %, respectively. That means, selection for better feed efficiency is not only an important economical but also an important ecological factor.
