PSIII-31 Effects of associative use of additives on performance, carcass characteristics and serum D-lactate in Nellore x Angus young bulls

Abstract The objective was to evaluate the effects of including virginiamycin or bacitracin in diets containing monensin or monensin plus virginiamycin and bacitracin on growth performance and carcass characteristics of feedlot young bulls. Seventy-two young bulls, with an initial average body of 417 ± 38.7kg were allotted in a completely randomized design. The bulls were placed in 18 pens (four animals per pen), with three treatments and six experimental replicates. The diets consisted of 85% concentrate and 15% of corn silage, with 11.4% CP, 75.7% TDN and 18.4% NDF. The treatments were: MON, 25 ppm of monensin in the diet; MONB: monensin plus 8.75 ppm of zinc bacitracin; and MONVM monensin plus 25 ppm of virginiamycin. Feedlot had 109d, with 27d of adaptation and 82d of experimental period. Performance was measured by daily intake records and weighing at the beginning and end of the feedlot. After feedlot, animals were slaughtered to measure carcass traits. Serum D-lactate was collected on day 7 and 43 of the experimental period. There was no significant effect of the additives on performance and most of the carcass traits (Table 1). However, young bulls receiving MONVM tended to have greater LM area. On the other hand, MON diet tended to increase marbling. Finally, there was a tendency for treatment x time interaction (P < 0.08) in the serum concentration of D-lactate. Bulls receiving MON had greater concentration on day 7 (109.5 µmol.µL-1), compared to other groups (66.7 and 89.9 µmol.µL-1 for MONB and MONVM, respectively). There was no effect of additives in the D-lactate content on day 43, being the treatments average 83.5 µmol.µL-1. In conclusion, the use of monensin and their association with virginiamycin or bacitracin did not affect performance but tend to influence carcass traits and serum D-lactate.

The objective of this study was to evaluate carcass yield, measurements, cuts, and fat deposition of sheep fed banana pseudostem hay and Tifton 85 grass hay, with or without virginiamycin. Thirty-three uncastrated male Dorper × Santa Ines crossbred lambs at five months of age, with an average body weight of 25.00 ± 1.95 kg, were used in a feedlot experiment. The following four diets were evaluated: Tifton 85 grass hay plus concentrate with virginiamycin, banana pseudostem hay replacing 60% of Tifton 85 grass hay plus concentrate with virginiamycin, Tifton 85 grass hay plus concentrate without virginiamycin, and banana pseudostem hay replacing 60% of Tifton 85 grass hay plus concentrate without virginiamycin. The experiment was set in a completely randomized design, in a factorial scheme, using orthogonal contrasts. The diet replacing 60% Tifton 85 grass hay by banana pseudostem hay without virginiamycin had no effect on carcass traits. The combination of virginiamycin and Tifton 85 grass hay provided increases in warm carcass weight, warm carcass yield, spine, omental and mesenteric fat deposition, and, regardless of roughage, increases in the thoracic perimeter.

The objective of this study was to evaluate the effects of the association of cottonseed processing method with chitosan on carcass traits and meat quality of lambs finished in feedlot. Eighty lambs with an average body weight of 20.6 kg, with 04 months of age, were distributed in a completely randomized design, in a 2 x 2 factorial arrangement. The factors were represented by two cottonseed processing method (whole or ground) and two levels of chitosan (0 and 136 mg/kg BW). The association of cottonseed processing method with chitosan in the lamb diet did not affect (P>0.05) carcasses traits. The pH, color, cooking losses, shear force, and proximate composition of meat were also not affected (P>0.05) by the processing method of cottonseed or its association with chitosan in the lamb diets. There was an increase in palmitoleic (c9-C16:1; P = 0.01) and conjugated linoleic (P = 0.02) fatty acids when ground cottonseed was associated with chitosan. Ground cottonseed associated with chitosan increases the concentration of unsaturated fatty acids in the meat of feedlot lambs.

Haematological and serum biochemical parameters are indicators of physiological, nutritional and pathological status of animals. Investigation of these parameters provide information for diagnostic purposes. The study was conducted to determine the influence of feeding graded levels of yam peel meal (YPM) as a replacement for maize on haematology; blood chemistry was evaluated in rabbits. Thirty- six (New Zealand white X Chinchilla) were randomly assigned to four dietary treatments in a completely randomized design with nine rabbits per treatment. The rabbits were fed diets containing 0, 12.5, 25 and 37.5% of Yam peel meal (YPM) as a replacement for maize, designated as T1, T2, T3 and T4, respectively. The experimental diets and clean drinking water were supplied ad libitum throughout the experimental period of nine weeks. At the end of the feeding trial, three rabbits per treatment were randomly selected for hematological and serum biochemical analysis. All the haematological and serum biochemical indices except AST were affected (P<0.05) by dietary inclusion of YPM. Although most of the parameters investigated were affected by rabbits fed test ingredient, the values fell within the normal literature reference values for rabbits. It can therefore be concluded that up to 37.5% inclusion level of YPM can be fed to growing rabbits without deleterious effects on health status.

This work aimed to determine the nutrient intake and quantitative aspects of sheep carcass from three different genetic groups. Eighteen animals with initial average body weight of 20.1kg were used in a completely randomized design, in a factorial 3x2 scheme (three different crossbreeds - 6 F1Dorper x non defined breed, 6 F1Somalis x non defined breed and 6 F1Santa Inês x non defined breed versus two diets). The diets fed to the animals were formulated with or without cashew nuts. The inclusion of cashew nut meal in the diet influenced nutrient intake. Differences of intake among the animal groups were observed as higher intake for F1Dorper x non defined breed (NDB), followed by F1Somalis x NDB and for F1Santa Inês x NDB. However, the control diet produced no difference among these genotypes. The average daily gain was lower for both crossbreeds when cashew nut meal was added in the diets. The evaluated crossbreeds and diets did not affect the feed:gain ratio. The carcasses analyses showed that the inclusion of cashew nut meal in the diets reduced the cold carcass weight and the rib weight. The addition of cashew nut meal in the diets for lambs reduces food intake and carcass yield. The crossbreed F1Dorper x NDB presented the higher rate of average daily gain.

Performance Results

Two experiments were carried out to determine the nutritional value and to evaluate the performance and carcass traits in the growing-finishing pigs fed on two types of semipurified glycerin, which were made from vegetable oil (SPGV) and mixed of animal + vegetable oil (SPGM). In the digestibility trial (experiment I) 32 crossbreed barrows were used with initial body weight of 45.08 ± 4.11kg. It were used three levels of inclusion (6, 12 e 18%) of semipurified glycerin (SPGV and SPGM) in the basal diet. The metabolizable energy (ME) value of glycerin were estimated by regression of ME (kcal/kg) intake associated with glycerin vs. glycerin intake (kg). The values of ME (kcal/kg) obtained were: 2,731 for SPGV and 2,210 for SPGM. In experiment II, 72 pigs (30.08 ± 1.65 to 60.58 ± 3.57) in growing and (60.83 ± 2.63 to 93.79 ± 5.72) in finishing phase, were allotted in a completely randomized design in a 2 x 4 + 1 factorial scheme, with two types of semipurified glycerin (SPGV and SPGA), four inclusion levels (4; 8; 12 and 16%), eight experimental unit and a control diet containing no glycerin (0%). All pigs were slaughtered to evaluate the carcass traits. The performance results suggest that it is feasible to use up to 16% of both semipurified glycerins on growing and finishing pigs feeding, without impairing performance and carcass traits.

Nutritional Strategies

Abstract The aim with this trial was to evaluate two nutritional plans with the addition of carbohydrases enzyme blend (CEB) on ruminal fermentation of grazing Nellore bulls in dry season. Five rumen cannulated Nellore steers (BW = 350 kg) were used. Animals were randomly assigned to a treatment sequence in a 5×5 Latin square experiment with 15 d-periods (10 d to diet adaptation and 5 d for data collection), following a completely randomized design, being the treatments: mineral-proteic supplementation (Fosbovi® Proteico 35; PS) offered at 0,1% BW (0 or 4.75 g/animal/day of CEB) or mineral-protein-energetic supplementation (Fosbovi® Proteico-Energético 25; PES) offered at 0.3% BW (0, 4.75 or 9.50 g/animal/day of CEB). The CEB was mainly composed by beta-glucanase and xylanase enzymes (Ronozyme® VP and Ronozyme® WX). Both enzymes and supplements were provided by DSM Nutritional Products Brasil S.A. Rumen fluid samples were collected on the last day of each experimental period before (0), and 2, 4, 6, and 8 h after supplements were offered. Data were analyzed using PROC MIXED of SAS. Steers fed PSE had greater (P ≤ 0.041) rumen concentration of acetate, propionate, and butyrate, and lower (P = 0.028) acetate to propionate ratio in comparison with animals fed PS. Rumen acetate concentrations were 61.6 and 58.8 mmol/L and rumen propionate concentrations were 15.2 and 13.7 mmol/L for animals under the PSE and PS, respectively. A quadratic effect (P = 0.048) for carbohydrases enzyme blend was observed in NH3-N ruminal concentration of PES animals, where 4.75 g/day level presented the lower concentrations compared to control (24.13 vs. 32.20 mg/dL). Furthermore, rumen concentrations of acetate (P = 0.002) and propionate (P = 0.021) linearly increased with enzymes inclusion for PSE plan. PSE nutritional strategy positively influence ruminal fermentation of Nellore steers in dry season and its effects can be enhanced with CEB inclusion of 4.75 g/day.

ABSTRACT: This study aimed at evaluating the effects of different desiccation periods of Urochloa decumbens on the initial development of Eucalyptus urograndis (clone C-219H). The experiment was conducted in 100 liter concrete boxes, previously filled with Dark-Red Latosol. U. decumbens was sown in all plots, except for the control sample without covering. After 95 days from sowing, the herbicide glyphosate (dose of 1,424 g a.e. ha-1) was sprayed at intervals of 0 (Apply-Plant), 7, 14, 21, 28 and 35 days before eucalyptus planting, plus a control sample without covering, totaling seven treatments. A completely randomized design with six replications was used. Eucalyptus plants were evaluated 30, 60 and 90 days after planting (DAP), when the height of the plants and the diameter of the stem were determined. At the end of the experimental period (90 DAP), the leaf area and the dry matter of leaves and stem were measured. It is possible to conclude that the Apply-Plant modality was harmful to some of the eucalyptus characteristics (E. urograndis - C-219H), while planting the seedlings in periods over 14 days after the desiccation of U. decumbens plants promoted a better development of the culture.

ABSTRACT The objective of this study was to evaluate the effects of probiotics and synbiotics on the performance and Enterobacteriaceae count of broiler chickens. A total of 640 one-day-old male broiler chicks were distributed in a completely randomized design with four treatments and eight replicates with 20 birds each. The treatments were: ration with performance enhancer (zinc bacitracin; positive control); ration without performance enhancer and probiotic/synbiotic (negative control); ration with probiotics; and ration with synbiotics. At 35 days, five birds from each treatment were euthanized and intestinal contents were harvested for determining the Enterobacteriaceae count. The performance data and average colony-forming units (CFUs) transformed as log CFU/g were subjected to analysis of variance and Tukey’s test. The effects of probiotics and synbiotics were observed in the initial phase, with supplemented birds exhibiting comparable weight gain to those supplemented with bacitracin. No effect of the treatment on broiler performance was observed after 42 days. The enterobacterial count was comparable among all experimental treatments. Supplementation with probiotics and synbiotics did not compromise the performance of broilers and did not alter the Enterobacteriaceae count.
