The researches followed the effects of powderYEA-SACC 1026 probiotic on some production and consumption indices in chicken broilers. The researches were effected on 75 meat chickens of Ross-308 hybrid, which were grouped in three lots of 25 capita/lot during 42 days. In the lot L1(E), for 42 days, in the mixed fodder was added YEA-SACC 1026 probiotic in proportion of 0.1% in breeding phase I (1-14 days), of 0.1% in phase II (15-35 days) and 0.1% in phase III (36-42 days). In the lot L2(E), for 42 days, in the mixed fodder was added YEA-SACC 1026 probiotic in proportion of 0.25% in breeding phase I (1-14 days), of 0.25% in phase II (15-35 days) and 0.25% in phase III (36-42 days). The chickens of all lots were weighted at the beginning of experiment and after that weekly being calculated the average body weight, average daily gain, fodder intake and fodder conversion index. The use of y YEA-SACC 1026 probiotic in lot L1(E) determined an increase of body weight with 16.26%, of average daily gain with 15.55% and the fodder conversion index was reduced with 29.16% given to Control Lot L(M). On the second place was situated the lot L2(E), in witch was administered 0.25% of YEA-SACC 1026 probiotic, with an increase of body weight of 8.32%, of average daily gain with 7.54% and the fodder conversion index was reduced with 21.78% given to Control Lot L(M). These superior results, registered in meat chickens from lot L1(E) YEA-SACC 1026 probiotic 0.1% and lot L2(E) YEA-SACC 1026 probiotic 0.25%, confirm the favourable influence of this probiotic on chicken broilers’ performances.

With the objective to evaluate different frequencies of supplementation on the performance and ingestive behavior of Nellore calves kept on Urochloa brizantha cv. Marandu pasture, 56 animals with initial average body weight (BW) of 174.5 kg were submitted to the following treatments: no supplement and 1x, 3x, and 7x supplementation per week. The supplement was provided in the amount of 3.5 g kg-1 of BW day-1. BW and evaluation of behavior were assessed every 28 days. The randomized block's design with two repetitions was used. The analyses of variance were carried out by the GLM procedure in the SAS software, and the means were compared by the Tukey’s test at 5% significance. The supplementation increased the average daily gain (ADG; P ? 0.05); however, it did not differ between frequencies (0.005, 0.190, 0.183, and 0.177 kg head-1 day for the no supplement treatment and 1x, 3x, and 7x per week, respectively). The animals in the no supplement treatment showed longer grazing time (P ? 0.05) compared to those receiving the supplement. However, results did not differ between frequencies (10.44, 8.57, 8.32, and 8.59 hours day-1 for no supplement treatments and 1x, 3x, and 7x per week, respectively). Thus, the frequency of supplementation can be reduced to once a week without reducing animal performance.

The objective was to evaluate the effect of partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus on performance and body weight components of sheep. Thirty hair lambs, with 19 kg ± 0.35 kg initial weight, were randomly divided into five treatments, namely: Tifton 85 Hay (HA); Tifton 85 Hay + fresh spineless cactus (HAFC); Tifton 85 Hay + dehydrated spineless cactus (HADC); fresh spineless cactus (FC); dehydrated spineless cactus (DC). In addition to the spineless cactus and hay, the complete mixture contained soybean meal, mineral salt and limestone in all treatments. Animals were confined for 75 days and then slaughtered. The weight of body components was recorded. Dry matter intake, total digestible nutrients intake and voluntary water intake were higher (p < 0.05) for the DC and HADC treatments. The average daily gain was 118 g day-1 and body weight at slaughter of 25.8 kg were not influenced (p > 0.05) by treatments. The cold carcass weight, rib eye area, weight and yield of the skin, liver, kidney and large intestine were higher (p < 0.05) for the DC and HADC treatments. Partial or total replacement of Tifton 85 hay with fresh or dehydrated spineless cactus, in complete diets for sheep, increases the weight of the cold carcass and non-carcass components.

Abstract Cecal inoculum collected from broilers fed a diet supplemented with xylanase showed increased gas production in an in vitro fermentation study with arabinoxylan-based substrates, indicating that intestinal microbiota can adapt to increase the capability to ferment arabinoxylans when pre-exposed to xylo-oligosaccharides (XOS) produced by xylanase. As the most abundant non-starch polysaccharides in a corn-soybean meal-based diet is arabinoxylan, this study tested the hypothesis that a blend of a xylanase and XOS will improve growth performance of pigs compared with those fed a diet supplemented with xylanase alone. One hundred twenty male crossbred (Landrace x Large white x Duroc) pigs (77 days average age; 30 kg average body weight -BW) were allocated to one of three treatments: CTR (control diet), XYL (CTR diet supplemented with 100 g/t of xylanase [Econase XT, AB Vista]) and XYL+XOS [CTR diet supplemented with 100 g/t of xylanase and XOS (Signis, AB Vista)]. Each treatment had ten replicates, with 4 animals each. The control diet was formulated with corn, soybean meal, DDGS and cassava meal as major ingredients. Pelleted diets were fed over 3 phases: grower (30–60 kg), finisher 1 (60–80 kg) and finisher 2 (80–100 kg). Average daily gain (ADG) and daily feed intake (ADFI) were measured from 30 to 100 kg and feed efficiency calculated (FCR). No treatment effects were observed on ADFI. Pigs offered the XYL+XOS had increased ADG (CTR = 1.058 vs XYL+XOS= 1.086 g/pig/d; P = 0.02) compared with those supplemented with xylanase alone (CTR = 1.058 vs XYL = 1.067 g/pig/d; P = 0.40). Feed efficiency was improved with XYL (2.65; P = 0.042) and XYL+XOS (2.60; P < 0.001) compared with CTR (2.71). These results suggest that xylanase in combination with XOS further improves daily gain and FCR compared with a xylanase alone. Interestingly the differences between XYL and XYL+XOS become more apparent in older animals, when the microbiome matures and possibly digests fiber more effectively.

Ninety-six Yorkshire barrows and gilts were used in each of two experiments conducted in the spring-summer (exp. 1), and fall-winter (exp. 2) months, respectively, to evaluate 15% Tower rapeseed meal (RSM) as a partial replacement for soybean meal (SBM) on an isonitrogenous basis in corn-based diets for pigs from 23 to 91 kg body weight. At 91 kg, half the number of pigs in each dietary group were slaughtered. Then, three levels of protein (12, 14 and 16%) in both corn-SBM and corn-SBM-RSM diets were fed to the remaining pigs in each group up to a final body weight of 125 kg. The energy level in the RSM diets was not adjusted to equal that in the SBM diets. In the 23- to 91-kg gain period, average daily gain (ADG) (P < 0.01) and backfat (P < 0.05) were lower in the RSM-fed pigs compared to SBM-fed pigs only in exp. 2. From 91 to 125 kg body weight, ADG (P < 0.05), feed intake (P < 0.01) and backfat (P < 0.01) were lower for RSM-fed pigs only in exp. 2. The heavy weight pigs fed RSM diets had a lower (P < 0.01) dressing percentage than SBM fed pigs in exp. 1. Reduction of dietary protein from the 16% fed up to 91 kg body weight to either 14 or 12% in the 91- to 125-kg gain period did not affect performance.

Abstract The objective of this study was to evaluate the impacts of castor meal, a by-product of the biodiesel industry, on growth performance and feeding behavior of heifers in a pasture production system in Northeast Brazil. Forty Holstein × Zebu crossbred heifers with an initial body weight of 257±26 kg were kept on a Brachiaria decumbens pasture under continuous grazing. The experiment lasted 140 days and was conducted in a completly randomized design with five levels of replacement of soybean meal with castor meal (0, 200, 500, 750, and 1000 g/kg of dry matter) in the supplements. Intake, digestibility, feeding behavior, performance, and carcass characteristics were evaluated. The total intakes of dry matter (DM), crude protein (CP), organic matter (OM), ether extract, and total digestible nutrients (TDN) decreased as the castor meal levels were increased. The digestibility coefficients of DM, CP, OM, and TDN decreased as the levels of castor meal in the supplement were increased. The castor meal levels in the supplement did not affect final body weight, average daily gain, feed conversion, hot carcass weight, or carcass dressing of the heifers. The use of supplements containing up to 1000 g/kg DM castor meal replacing soybean meal reduced the DM intake but did not change the average daily gain and feed efficiency of the heifers. Thus, the use of castor meal is a recommendable strategy to reduce production costs in a beef cattle grazing system.

Five corn-soybean-based diets were formulated to contain 0, 15, 20, 25, or 30% raw peas and fed for 35 d to ninety-six 21-d-old pigs. Raw peas were included at the expense of corn and soybean meal. Increasing levels of raw peas depressed daily gain (P = 0.07), feed intake (P = 0.04) from days 21 to 56. Specifically, pigs fed diet with 25% peas had 19 and 25% lower average daily gain (ADG) and average daily feed intake (ADFI), respectively, than pigs fed the diet with 0% peas. The body weight (BW) was also linearly reduced (P = 0.10) on day 56. However, diets did not affect feed efficiency. Key words: Growth performance, peas, pig

Anim. Sci. 94: 115–118. One hundred and ninety-two piglets (7.2±0.50 kg body weight) were fed corn–wheat–soybean meal based-diets to determine dietary Lys requirement in a 2×4 factorial setting [two sanitation conditions (SC): clean and unclean, and four dietary lysine contents: 0.94, 1.09, 1.25 and 1.43%]. The average daily gain (ADG) and gain to feed ratio (G:F) linearly increased (P<0.05) with dietary lysine contents, but were lower (P<0.0001) under unclean sanitation conditions from day 0 to 7 but not from day 8 to 21. Overall, dietary lysine contents did not affect average daily feed intake (ADFI), but unclean sanitation conditions reduced (P<0.01) ADFI; however, ADG was increased by both dietary lysine contents and SC? (P<0.001), whereas only dietary lysine contents affected G:F.

The experiments aimed to study about the performance and diet digestibility of male Garut lamb were a diet containing  Ipomea reptans seeds. Twenty two Garut sheeps at the age of 6-8 months with an average body weight of 16.17±1.33 kg were divided into four diet treatments containing 0%, 10%, 20%, and 30% Ipomea reptans seed and maintained for 10 weeks to measure the performance and digestibility of the diet. The study was conducted experimentally and the data collected and tested by Duncan’s test. The results showed that the use of Ipomea reptans seeds up to 30% increased (P<0.05) feed intake, average daily gain, dry and organic matter digestibility, but it had no effect on feed conversion. In Conclusion, the use of Ipomea reptans seed up to 30% yielded the best performance and diet digestibility and produced the same quality of diet.
