Metabolizing Enzyme

The effects of feeding dehydrated poultry manure (DPM) to steers during a 180-day finishing period on performance, blood and urine parameters and liver drug-metabolizing enzyme activities were evaluated and compared to control steers fed a conventional diet. No significant treatment differences were observed for average daily gain, daily dry matter intake and feed efficiency; however, steers fed the DPM diet had a slightly higher dry matter intake and a lower feed efficiency. Aside from an initial refusal of the DPM diet and a moderate diarrhoea during the last month of the study there were no clinical signs of toxicity. Blood and urine parameters examined showed no abnormal differences, fluctuations or trends between steers fed either the DPM or control diet. There was no evidence of pathological changes attributable to DPM feeding in gross or histological examinations. Liver microsomal cytochrome-P-450-dependent drug-metabolizing enzyme activities were not influenced by the feeding of DPM. With the exception of rib eye area, which was significantly smaller (P < 0.01) for steers fed the DPM diet, carcass traits were not affected.

Supplementing a control diet of ground alfalfa (CON) with monensin (MON), chlortetracycline (CTC) or tylosin (TYL) did not affect (P < 0.05) dry matter intake or average daily gain of market lambs. Feed efficiency with CTC was less than with the unsupplemented control (CON) (6.22 vs. 5.68) (P < 0.05). Mean digestibilities of dry matter, acid detergent fiber and neutral detergent fiber were lower (P < 0.05) with all antibiotic treatments than the CON diet. Relative to CON, nitrogen digestibility was increased with MON (66.3 vs. 70.9%) while that of energy was reduced with TYL (P < 0.05). Rumen ammonia and acetic, propionic and butyric acid concentrations were not influenced by any of the treatments. MON, CTC and TYL were not effective supplements for lambs fed alfalfa finishing diets. Key words: lamb, chlortetracycline, monensin, tylosin, alfalfa hay, digestibility

Abstract The aim of this trial was to evaluate the effect of encapsulated calcium ammonium nitrate as a partial substitute for soybean meals in the concentrate dry matter intake, average daily gain and feed efficiency of Nellore young bulls under grazing conditions, during the dry season. Sixty-four weaned Nellore (initial BW = 177.46±3.77 kg and 9 mo old) were used in a completely randomized assay. The study lasted 84 days on the dry season. Animals were allotted into 16 paddocks of 1.0 ha each of Urochloa brizantha, randomly assigned into one of two treatments: (CTL) supplement with 25% CP, without nitrate inclusion and; (ENP): supplement with 25% CP, with a inclusion of 50 g of encapsulated calcium ammonium nitrate to each 100 kg of body weight. Animals were fed with concentrate at 1.0% of body weight. Concentrate offered was monitored daily as well as his refusals were collected and weighed to determine daily concentrate dry matter intake (DMI) and feed efficiency (F:G). Animals were weighed every 28 d for calculating average daily gain (ADG). Data were analyzed as a completely randomized design, using ANOVA (α = 0.05). No effects of treatments (P &gt; 0.3487) were observed for final BW (246.69 kg). The same for concentrate dry matter intake (P &gt; 0.0550). Animals consumed 2.34 kg of supplement per day. The average daily gain (0.832 kg, P &gt; 0.2649) and feed efficiency (0.356 kg, P &gt; 0.7315) were not affected by the inclusion of nitrate. The inclusion of encapsulated calcium ammonium nitrate in supplement to Nellore young bulls under grazing conditions during the growing phase did not affect the performance.

Abstract The objective of this study was to evaluate the growth performance and carcass traits of finishing bulls fed diets containing, on dietary dry matter basis, different levels of corn wet distillers bran plus solubles (WDBS; 0, 15, 30 or 45%) added with or without corn oil (CO; 0 and 3%). A total of 205 Nellore bulls (390 ± 25 kg initial BW) were blocked by initial body weight, distributed in 40 pens and pens within weight block were randomly assigned to treatments in a 2 × 4 factorial arrangement. Diets were isonitrogenous and contained 8.5% sugarcane bagasse and 91.5% concentrate (ground corn, soybean meal, pelleted citrus pulp, urea, mineral). The WDBS (FlexyDDG®) and the corn oil were from SJC Bioenergia (Quirinópolis, Goiás, Brazil). Data were analyzed using the PROC MIXED procedure of SAS. An interaction between CO × WDBS levels was observed for dry matter intake (DMI; P = 0.032). In diets without CO, increasing levels of WDBS linearly (P = 0.004) reduced the DMI, but in diets containing 3% CO, increasing levels of WDBS quadraticaly affected the DMI (P = 0.002). No effects of CO, WDBSF levels or CO × WDBS levels were observed for final body weight, average daily gain, hot carcass weight and dressing percentage. Feed efficiency tended (P = 0.07) to be greater for bulls fed diets containing CO (0.154 vs. 0.144). Increasing levels of WDBS tended (P = 0.09) to increase the feed efficiency. In summary, increasing levels of WDBS in finishing diets linearly (in diets without CO) or quadratically (in diets with CO) reduces the dry matter intake. Adding CO and WDBS tend to increase feed efficiency.

Entire male (EM) pigs (152; ∼30 kg body weight) were used to examine immunocastration using Improvest and feeding ractopamine on growth performance, carcass and meat quality, and fatty acid composition. Timing for administering second dose of Improvest compared dosing at 4 and 8 wk pre-slaughter. A factorial arrangement evaluated two genotypes [Large Whites and Duroc crossbreds (Durocs)] by five management regimens (EM fed control diet, EM fed ractopamine, second dose Improvest 4 wk pre-slaughter, second dose Improvest 8 wk pre-slaughter, second dose Improvest 4 wk pre-slaughter plus ractopamine). Average daily gain and gain to feed (G:F) were generally greater (P ≤ 0.01) in Durocs. Immunocastration increased (P < 0.01) dry matter intake (DMI); feeding ractopamine decreased (P < 0.02) DMI and increased (P < 0.03) G:F. Immunocastration decreased (P < 0.04) carcass and lean yields; feeding ractopamine increased (P < 0.04) carcass weights, lean yield, muscling, and longissimus shear force while decreasing (P < 0.01) backfats. Immunocastration did not affect loin pH, color, drip loss, and shear force. Timing for second Improvest dose did not affect most growth performance, carcass, and meat quality traits except for greater (P < 0.02) backfats when administering dose 8 wk pre-slaughter. Effects of immunocastration and (or) feeding ractopamine were relatively consistent in both genotypes evaluated.

This study was conducted to determine optimum test duration for measuring performance, feed intake and feed efficiency. Sixty young Nellore bulls were submitted to feeding performance test and fed in individual pens to determine feed intake and performance over 112 days. Body weight was determined every 28 days, after fasting of water and feed for 16 hours. Changes in variance, relative variance and Pearson and Spearman correlations among data from shortened test periods (28, 56 and 84 days) and full test period (112 days) were used to determine optimum test duration. Test duration for average daily gain, dry matter intake, feed:gain ratio and residual feed intake could be shortened to 84, 28, 84 and 84 days, respectively, without reducing significantly the reliability of measurements for animals fed in individual pens.

Abstract The objective of this trial was to evaluate the effects of increasing levels of narasin in the diet of lactating ewes on dry matter intake (DMI) and average daily gain (ADG) of their lambs. Forty crossbred ewes Dorper x Santa Inês with their lambs were assigned to a randomized complete block design (10 blocks and 4 treatments). The treatments were defined by the inclusion of narasin to a base diet (16.8 ± 0.66 of CP) containing 50% of concentrate and 50% of Brachiaria brizanta hay, as follow: 0N - control diet; 13N - 13 mg of narasin/kg of DM; 20N - 20 mg of narasin/kg of DM; 27N - 27 mg of narasin/kg of DM. The experiment lasted from 14 to 70 days of lactation. From the second to the tenth week of age the lambs received initial concentrate (57.0% corn; 25.0% soybean meal; 1.5% limestone; 1.5% of mineral mix; 5.0% of sugarcane molasses and 10% of milk replacer; composition: DM=89.3%; CP = 21.1%; FDN = 8.9%; FDA=2.7%) (ad libitum) in a private feeder. All data were analyzed using the MIXED procedure of SAS. The lambs were weighed weekly after 5-hours fasting. The orts were quantified weekly to determine the DMI. There was no effect of the supply of narasin to the ewes on the DMI by the lambs (0N = 0.126; 13N = 0.088; 20N = 0.153; 27N = 0.145 kg/d; P &gt; 0.05). However, the supply of narasin decreased the ADG (0N = 269.3; 13N = 259.60; 20N = 264.02; 27 = 228.01 g; P &lt; 0.01) of lambs. In conclusion, the use of narasin for the ewes did not benefit lamb performance.

The study was conducted for 48 days to assess the use of kaun as a source of mineral for Hest African Dwarf sheep. The study was in two parts. Experiment l involved the use of milled kaun mixed with formulated concentrate consisting of wheat offal (50%), palm kernel cake (25%) and dried brewer's grains (25%). Experiment II was the use of dissolved kaun administered to the animals in form / drenching. Each group of animals in experiment 1 was allocated to experimental diet containing milled kaun (0.00, 0.14, 0.28, 0.45 and 0.56g/kg body weight/ram. day) and to kaun solution (0,2,4,6 and 8g: 10ml of water/ram/day) in experiment II. In Experiment I, significant (P<0.05) effects of the diets were observed on average daily gain, dry matter intake and water consumption. The rams on D3 significantly (P<0.05) performed better in daily gain, dry matter intake and feed efficiency than those on other dietary treatment. Water consumption increased with increasing level of kaun in the diets. Animals on D5 had the highest water consumption. No significant (P>0.05) effects of the diets were observed on faecal and urinary mineral outputs of the rams fed kaun supplemented diet. The concentration of these minerals was higher at the end of the experiment than at the beginning thereby giving positive balance. Significant (P<0.05) negative mineral balance was noticed between serum mineral before and after the experiment. This could suggest that mineral utilization was encouraged by kaun inclusion in the concentrate feed. In Experiment II, there were significant (P<0.05) effects of the test diets on average daily gain, dry matter intake and water consumption. Diet 4 (g/10ml of water/ram/day) and D5 (8g:10ml of water/ram/day) performed better with an average daily gain of 100g/d and 92.9g/d; dry matter intake, 70g W0.7kg and 66g/W0.75kg; feed efficiency 0.700 and 0.710, respectively. Water consumption also increased with increase in the concentration of kaun solution but water consumption in treatment groups was lower than in the control (0.10L/kg body weight). The results of this study suggest that 0.28g kaun kg body weight ram/d) promoted better performance in experiment / while 6g kaun/10ml of water, or 8g kaun 10ml of water/ram/d promoted better performance in experiment II. These levels of kaun as a source of mineral in sheep production are therefore recommended for optimum performance.

This research aimed to evaluate the performance of fattened madura cattle fed on coffee husk as a source of fibre to substitute grasses. Twenty Madura steers aged approximately 1.5 to 2.0 years with initial weight of 165-190 kg were divided randomly into four different experimental diets, namely R0= 90% concentrates +0% coffee husk +10% napier grass, R1= 90 % concentrates +3.33% coffee husk +6.67% napier grass, R2 = 90% concentrate +10% 6.67% coffee husk +3.33% napier grass, R3 = 90% concentrates 90% + 10% coffee husk +0% napier grass. The feed was given at 3% body weight of dry mater. The cows were kept in individual pen for two months. Variables measured were dry mater intake, feed efficiency, average daily gain (ADG), digestibility of feed and income over feed cost. Data obtained were analyzed using analysis of variance based on randomized block design followed by Duncan’s multiple range test. Results showed that dry matter intake, ADG, feed efficiency and feed digestibility of cattle on each treatment of the feed were not significantly different (P > 0.05). Average of dry matter intake and daily gain for R0, R1, R2, and R3 were 6.01, 5.84, 5.73 and 5.62 kg/head/day and 0.88, 0.87, 0.84 and 0.93 kg/head/day respectively. While the average of feed efficiency and DM digestibility for R0, R1, R2, and R3 were 14.64, 14.89, 14.65 and 16.54 % and 84.82, 84.37, 83.47 and 83.30 %, respectively. It is concluded that the used of 10% coffee husk as a source of fibre for substitution of napier grass can be used without negative effect on madura’s cattle performances and tend to give higher values of IOFC on fattening program.
