UTILIZATION MANURE DEGRADED USING BLACK FLY LARVAE (Hermetia illucens L) SUBSTITUTING FISH MEAL IN RATION ON LOCAL GROWING CHICKENThe objective of this study was to evaluate the performance of local growing chicken fed ration containing manure flour degraded (MFD) by Larva of black fly (Hermetia illucens L). This experiment was carried out using a complete Randomized Design (RAL), consisted of 4 treatments and five replications in each treatment as follows: R0 = Rations with 15% fish meal + 0% MFD, R1 = 10% fish meal + 5% MFD, R2 = 5%  fish meal + 10% MFD, and R3 = 0% fish meal + 5% MFD. The variables measured were feed consumption, average daily gain and feed efficiency. Statistical analysis was done according to the procedure using analysis of variance. Results obtained in the research showed that treatments did not affected significantly feed consumption, average daily gain and feed efficiency of local grower chicken. Therefore, it can be concluded that MFD can be used as the candidate ingredient replacing fish meal in ration of the local grower chicken.Key words: Manure flour degraded, fish meal, black fly, kampong growing chicken

Dietary ractopamine increases lean tissue deposition and responses increase as dose is increased provided sufficient dietary lysine is supplied. In Australia, diets supplemented with ractopamine (RAC) are formulated with 0.56 g available lysine per MJ digestible energy. The present study was conducted to investigate the interactions between dietary RAC and lysine on growth and carcass characteristics in ad libitum fed (13.8 MJ/kg) boars and gilts. The study involved 108 individually penned pigs at 17 weeks of age (64.1 ± 0.57 kg) in a 2 by 2 by 3 factorial design, with the respective factors being sex (gilt or boar), dietary lysine (low and high, i.e. 0.56 or 0.65 g available lysine/MJ digestible energy, respectively) and dietary RAC (0, 5 or 20 mg/kg) for 28 days. Over the 28-day study duration, both lysine diets containing dietary RAC were sufficient to elicit a response in average daily gain (ADG) (+5.8%, P = 0.026) and carcass weight (3%, P = 0.045), but not in feed efficiency (FE) (P = 0.555). However, over the period of the first 7 days, there were interactions between the effects of RAC and lysine for FE (P = 0.025) and ADG (P = 0.023), with both traits being responsive only to dietary RAC containing the high lysine, which increased FE (+9.1%, P = 0.002) and ADG (+7.2%, P = 0.068). Dietary RAC improved FE in the latter stages of the study, namely Days 15–21 (+5.7%, P = 0.031) and Days 22–28 (+4.9%, P = 0.040). The high RAC diet reduced carcass P2 backfat (–16.5%, P < 0.001) and fat tissue deposition (–6.2%, P = 0.074) and high lysine tended to reduce fat tissue deposition (–13.3%, P = 0.072). A sex by lysine interaction (P = 0.043) was observed for lean tissue deposition at 28 days, such that only the high-lysine diet increased lean deposition in boars (+11%, P < 0.05) but not in gilts. Dietary RAC tended to increase lean deposition (+14.0%, P = 0.067) in the first 14 days; however, only the high RAC diet increased lean deposition (+9.6%, P < 0.05) over 28 days. In conclusion, the current recommended supplementation levels of lysine for commercial gilts and boars fed RAC may limit the response to dietary RAC if the feeding regime is for short durations and boars will not maximise their lean tissue deposition rates.

FERMENTATION PERIOD EFFECT OF BANANA LEAF IN RATION ON BROILER FEED EFFICIENCY. This study was done to evaluate the fermentation period effect of banana leaf in ration on broiler feed efficiency. Animals used in this study were sixty broilers (Hubbard strain) at the age of three week old. Research was conducted using completely randomized design involving four treatments with five replications in each treatment. Treatments used were as follows: Ration containing banana leaf without fermentation (R0), Ration containing banana leaf fermented at five days (R1), Ration containing banana leaf fermented at ten days (R2), and Ration containing banana leaf fermented at fifteen days (R3). Data were analyzed by variance analysis. Significantly difference treatment effects on variable measures were tested using honestly significant difference (HSD). Variables measured were feed consumption, average daily gain, and feed efficiency. Results showed that that treatments had significantly difference (P<0,01) on feed consumption, average daily gain and feed efficiency. It can be concluded that ration containing banana leaf fermented at ten days produce the best feed efficiency of broilers. Keyword : Fermented banana leaf, feed efficiency, broiler

A feeding trial lasting 84 days was conducted using 45 weaned rabbits (with weught range 643-652g) to investigate the effect of using millet husk (MH), Rice bran (RB) and Sorghum panicle (SP) as fibre sources for growing rabbits in a completely randomized design. Forty-five young rabbits were randomly assigned to 3 different groups. Fifteen rabbits per treatment. MH, RB, and SP were randomly incorporated at the rate of 150g/kg of diets. The diets were isonitrogenous (16% CP). The effect of these fibre sources on average daily feed intake (ADFI), average daily gain (ADG), feed efficiency nutrient digestion was determined. Results of the study showed that rabbits on MH based diets had a significantly higher (P>0.05) ADFI, feed efficacy and final weight. Though the results of the ADG and average daily crude fibre intake was highest in the MH diet, it was not significantly (P>0.05) different from the results obtained for RB. The RB diet had a better digestibility of all nutrients. This was however not reflected in the performance of  the rabbit. It was concluded that different sources of fibre affect the performance of rabbits differently. In this study, MH was superior to MB and SP as a fibre source for growing rabbits. It is therefore necessary to study the effect of the different fibre sources before incorporating them in concentrate diets.

EFFECT OF UTILIZATION OF COMMERCIAL AND LOCAL CONCENTRATE DIETS ON FEED EFFICIENCY OF STARTER PIGS. The present study was conducted to determine the comparison of feed efficiency of starter pigs consumed local and commercial concentrate diets. Twenty castrated male pigs were allocated in individual crate. Experimental design used in the present study was completely randomized design (CRD) with four treatments and five replications. Treatments were arranged as follows: R1=Pokphan’s concentrate diet 32% + yellow corn 50% + rice bran 18%; R2= Benfeed’s concentrate diet 32% + yellow corn 50% + rice bran 18%; R3= Cargill’s concentrate diet 32% + yellow corn 50% + rice bran 18%; R4= Local’s concentrate diet 32% + yellow corn 50% + rice bran 18%. Variables measured were daily feed consumption, daily gain, and feed efficiency. Research results showed that treatments gave no significant effect on daily feed consumption, daily gain and feed efficiency. It can be concluded that starter pigs gave a similar respons when either local concentrate or commercial concentrate diets. Keywords: commercial concentrate, local concentrate, starter pig

The influence of high (HE) and low (LE) digestible energy diets fed for two 1-hr periods per day on the performance of Duroc × Yorkshire, Hampshire × Yorkshire, or Yorkshire × Yorkshire pigs marketed at 68, 91 or 114 kg liveweight was studied. Under the feeding system employed, daily feed intake averaged 2.01 kg and did not differ between dietary groups. The HE diet containing 3652 kcal DE/kg improved (P < 0.01) rate of gain and feed conversion compared with the LE diet containing 2757 kcal DE/kg. DE requirement averaged 9.89 Mcal/kg gain and did not differ between dietary groups. Carcasses from pigs fed the HE diet had higher dressing percentage, greater total backfat thickness, and lower ratio of loin to backfat thickness, percent lean in the ham face, ham as a percent of carcass and Canadian ROP score.Barrows had a higher daily feed consumption and average daily gain but were inferior to gilts in feed conversion. Gilts were superior to barrows in all carcass measurements except dressing percentage, where differences were nonsignificant.Breeding groups differed (P < 0.01) in rate of gain, feed conversion, and dressing percentage and their carcasses differed in loin area and length. Feed required per unit gain increased with increasing market weights but gain did not differ. With increasing market weights, dressing percentage, length, loin area and total backfat thickness increased while the ham as a percent of carcass and ROP scores decreased. Market weight did not significantly alter the ratio of loin area to total backfat, suggesting that the present Canadian carcass grading standards should be extended to cover a greater weight range without penalty.Major significant interactions for average daily gain existed between diet by sex and diet by breeding group and for feed conversion between diet by sex. The data indicate that sex and breeding background of market pigs are important considerations in formulation of energy requirements. Use of LE diets or of feeding methods that restrict DE intake may mask potential differences that exist between groups.

Abstract The goal of this study was to evaluate the performance and the carcass traits of Nelore cattle progenies from bulls selected by contrasting traits for precocity, growth and muscularity, through the Expected Progeny Difference (EPD). One hundred and five Nelore bulls (initial weight of 350kg±15kg) and 20 months of age were confined and fed with same diet (73% of concentrate). Thirty-two animals were selected to create the contrasting groups for precocity, growth and muscularity (16 animals assigned as a low EPD group - LEPD and 16 animals assigned as a high EPD group - HEPD), based on the EPD of their parents. The ribeye area and backfat thickness were performed by ultrasonography of 12–13th rib fat thickness and longissimus muscle area (LMA), as well as rump fat thickness (RF) measurements. Animals were harvested after 100 days and during the deboning, meat cuts were weight for cutting yield. The animals selected for the HEPD group had greater average daily gain (P = 0.006), which can be explained by the higher feed intake (P = 0.006). However, there are no difference between groups for the final body weight (P = 0.254) and feed efficiency (P = 0.715). The LEPD group presented higher dressing percentage (P = 0.028). Although the groups evaluated did not presented difference in LMA (P = 0.329) and weight of longissimus muscle (P = 0.480), the weight of rump displayed heaviest in the HEPD (P = 0.037). There was no difference between groups for RF (P = 0.086). Nevertheless, backfat thickness was higher in HEPD group (P = 0.006). The present study indicates that Nelore cattle progenies, with parents displaying higher potential for precocity, growth, and muscularity, show greater backfat thickness and weightiest of rump than the other genetic backgrounds.

Abstract Four hundred and thirty-two beef steers (346.3 ± 63.7 kg BW) were used to determine the effects of Zn source on feedlot cattle fed ractopamine hydrochloride. Cattle were blocked in groups of 54 by BW and housed in 48 pens containing 9 steers per pen. Pens within a weight block were randomly assigned to treatments in a 2 x 3 factorial arrangement, with factors being: 1) 0 or 30.1 mg of ractopamine HCl/kg DM fed during the final 29 days on feed; and 2) Zn source: 90 mg of supplemental Zn/kg DM from ZnSO4; Zn sulfate (67%) + Zn methionine (33%); and Zn from Zn hydroxychloride, fed through the entire feeding period. Cattle were fed a high concentrate finishing diet for 154 d and slaughtered at a commercial abattoir. Average daily gain, DMI, feed efficiency and carcass characteristics were determined after slaughter. Zinc source had no impact on live animal performance. Cattle fed ractopamine HCl had greater (P &lt; 0.01) final BW, greater (P &lt; 0.001) ADG, improved (P &lt; 0.001) G:F, heavier (P &lt; 0.01) HCW, and larger (P &lt; 0.05) longissimus muscle compared to non-ractopamine supplemented steers. There was a Zn source by ractopamine interaction (P &lt; 0.01) for dressing percentage. Cattle receiving ractopamine HCl with Zn hydroxychloride had a greater dressing percentage (P &lt; 0.05) when compared to ractopamine HCl cattle fed other Zn sources. Cattle receiving ractopamine HCl with Zn sulfate had a lesser dressing percentage (P &lt; 0.05) when compared to ractopamine HCl cattle fed other Zn sources. Additional Zn source by ractopamine HCl interactions were not significant. These data indicate that Zn source has minimal impacts on feedlot steer performance and carcass characteristics when supplemented to cattle receiving 0.0 or 30.1 mg of ractopamine HCl/kg DM.

Abstract This experiment evaluated the impacts of bovine appeasing substance (BAS) administration on performance, health, and physiological responses of feedlot cattle during a 45-d receiving period. A total of 342 recently-weaned Angus-influenced steers, originating from 16 cow-calf operations, were obtained from an auction yard on d -1 and road-transported (12 h) to the feedlot. Upon arrival on d 0, body weight (BW) was recorded and steers were ranked by BW and source and assigned to receive BAS (Nutricorp, Araras, SP, Brazil; n = 171) or placebo (diethylene glycol monoethyl ether; CON; n = 171). Treatments (5 mL) were topically applied to the nuchal skin area of each animal. Within treatment, calves were allocated to 1 of 24 drylot pens (12 pens/treatment) and received a free choice total-mixed ration from d 1 to 45. Calves were assessed for bovine respiratory disease (BRD) signs and feed intake was recorded from each pen daily. Steer BW was again recorded on d 1, 7, 17, 31, and 45, whereas blood samples were collected from 5 steers/pen concurrently with each BW assessment. Average daily gain was greater (P = 0.05) in BAS vs. CON calves, although final BW did not differ (P = 0.36) between treatments. No treatment effects were detected for feed intake (P = 0.95), resulting in greater (P = 0.05) feed efficiency in BAS vs. CON steers. No treatment effects were detected (P ≥ 0.37) for plasma concentrations of haptoglobin, whereas plasma cortisol concentrations were greater (P = 0.05) in CON vs. BAS steers on d 7 (treatment × day; P = 0.07). Incidence of BRD was greater (P ≤ 0.05) in BAS vs. CON on d 6 to 10 and d 18 to 21 (treatment × day; P &lt; 0.01), although overall BRD incidence did not differ (P = 0.24) between treatments. The number of antimicrobial treatments required per steer diagnosed with BRD symptoms to recover from sickness was greater (P = 0.04) in CON vs. BAS calves. No treatment differences were detected (P ≥ 0.41) for mortality incidence, or proportion of steers removed from the experiment due to extreme sickness. Results from this experiment indicate BAS administration upon feedlot entry improved average daily gain by enhancing feed efficiency. Administration of BAS facilitated earlier detection of BRD and reduced the need for antimicrobial treatments. Collectively, these results suggest BAS administration as a promising strategy to benefit performance and immunocompetence of feedlot receiving cattle.

Abstract Objectives were to compare feedlot performance and carcass traits of F1 beef × Holstein steers and Holstein steers. Angus or Limousin × Holstein crossbred [n = 27; age = 12 ± 3 months; body weight (BW) = 435 ± 8 kg] and Holstein (n = 20; age = 11 ± 2 months; BW = 400 ± 9 kg) steers were fed at the Pennsylvania Department of Agriculture Livestock Evaluation Center for 111 days. Feed intake was recorded using the GrowSafe Feed Intake Monitoring System (Model 4000E, GrowSafe Systems Ltd., Calgary AB, Canada). The diet contained corn silage, dried distillers grains, soybean meal, and cracked corn and was formulated to meet or exceed the requirements of beef cattle (NASEM, 2016). Growth performance variables of interest and carcass measurements were analyzed with the Mixed procedure of SAS (SAS 9.4; SAS Institute Inc., Cary, NC). USDA assigned quality grades (QG) and yield grades (YG) were analyzed the with GLIMMIX procedure of SAS. Breed was a fixed effect in all models. There were no differences (P &gt; 0.05) between breeds in average daily gain or feed efficiency. Crossbreds exceeded Holsteins in initial (P &lt; 0.01) and final BW (P = 0.01), dry matter intake (P = 0.03), hot carcass weight (P &lt; 0.01), backfat (P = 0.03), and ribeye area (REA; P &lt; 0.01). Thirty-five percent (35%) of the Holsteins received a QG of Choice or above while 74% of crossbreds graded USDA Choice or above (P = 0.01). However, 75% of Holsteins were YG 2 or lower while only 45% of crossbreds achieved YG 2 or less (P = 0.05). There was no improvement in efficiency when crossbreds were compared to Holsteins; however, carcasses from crossbreds were more likely to grade USDA Choice or above while yielding greater REA and backfat than Holsteins.
