Two experiments were conducted to investigate the nutritive value of sausage casings prepared from cattle hides as a protein source for day-old hybrid (Hubbard × Hubbard) broiler chickens. The results demonstrate that sausage casings are an available protein source for broiler chicks that can be substituted for soybean meal at levels up to 8% of the feed without affecting average daily gain and feed efficiency.

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

This study was designed to evaluate the effects of dietary supplemental DL-methionine (MET) on live performance and meat yield for broilers raised to a common weight. A total of 1552 one-day old Ross 708, sexed broilers were randomly distributed to 32 pens resulting in eight treatments (TRT) of four replicates with 44 male or 53 female/pen. A randomized complete block with a 2 × 4 (sex × 4 MET levels 0, 0.5, 1, and 2 g/kg) factorial arrangement of TRT was used. A common weight of 2400 g was approached by day 46 (1 and 2 g MET/kg feed) and day 48 (0 and 0.5 g MET/kg feed). Supplementation of MET at 1, and 2 g/kg had a lower (p < 0.01) feed conversion ratio (FCR) at day 46/48 than broilers fed 0.5 g MET/kg. Broilers without supplemental MET had the worst (p < 0.01) feed conversion and average daily gain (ADG) at day 46/48. Birds fed 0 g MET/kg of feed had lower (p < 0.05) whole eviscerated carcass without giblets (WOG), yield than birds fed 2 g MET/kg of feed. Additionally, birds fed 0 g MET/kg of feed had lower (p < 0.05) breast fillet and tender percent yields than birds fed supplemental MET. Elimination of MET from organic broiler diets resulted in reduced ADG, breast fillet yield and feed efficiency of meat yield of broilers raised to day 46/48. Reduction in MET supplementation below current levels reduced the efficiency of meat production of organic broilers raised to day 46/48.

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

Context It is hypothesised that the use of processed soybean for feedlot beef cattle improves feed efficiency and produces beef with a better fatty acid profile for human health. Aims This study aimed to evaluate average daily gain, feed efficiency, carcass traits, chemical composition, fatty acid profile and colour in the beef of young bulls fed diets with ground or extruded soybean. Methods A total of 60 young Zebu bulls (Nellore or Nellore crossed with other Zebu breeds) with an average initial liveweight of 320 ± 8.12 kg and an average initial age of 20 ± 2 months were randomly assigned to receive one of the following diets for 84 days: dehulled and defatted soybean meal (3.22% of ether extract), ground soybean (6.51% of ether extract) or extruded soybean (6.37% of ether extract). The fatty acid profiles of these animals were analysed using high-resolution gas chromatography. The CIE L*a*b* colour space model was used to numerically describe the colour during the aging period (0, 7, 14 and 21 days). Key results Diet had no effect on the average daily gain, feed efficiency or carcass traits of the animals (P &gt; 0.05). Protein, ether extract and ash composition of the Longissimus lumborum (LL) muscle were not affected (P &gt; 0.30) by the use of processed soybean grains. The ground soybean diet decreased oleic acid and C18:2 c9, t11 concentrations, but increased C18:2 t10, c12 and trans-octadecenoic acid isomer concentrations in the LL muscle compared with those in the dehulled and defatted soybean meal and extruded soybean diets (P &lt; 0.05). Muscle from bulls fed processed soybean exhibited greater concentrations of stearic acid and saturated fatty acids, and a lower concentration of unsaturated fatty acids, as well as a decreased unsaturated fatty acids:saturated fatty acids ratio (P &lt; 0.05). Processed soybean grains did not affect (P &gt; 0.05) the LL muscle pH or colour. Conclusions The use of ground or extruded soybean did not affect the performance, carcass traits, LL protein, ether extract or ash composition, and had no impact on beef colour compared with the diet containing soybean meal. Processed whole soybeans in the diet did not increase unsaturated fatty acids or conjugated linoleic acid in beef compared with a diet without soybean meal. Implications Up to 20% of ground or extruded soybean in feedlot beef cattle can be used as a replacement for soybean meal and corn.

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.

A total of eight 11-wk trials were conducted to evaluate the productivity and aggression at grouping of grower-finisher pigs [initial body weight (BW) = 31.8 ± 5.4 kg (mean ± SD), n = 2304] in two group size treatments (18 and 108 pigs pen-1). Pigs were housed on fully-slatted floors, provided one wet/dry feeder space for every nine pigs, and a floor space allowance of 0.76 m2 pig-1 in both group sizes. The level of aggression at grouping was recorded for 2 h starting 0, 24 and 48 h following grouping into small and large groups. Pigs were weighed on weeks 0, 2, 5, 7 and 11, and average daily gain (ADG) was obtained. Average daily feed intake (ADFI) was recorded during two periods (weeks 2 to 5 and 7 to 11). There was no difference in percentage of time spent on aggression between two group sizes up to 48 h following grouping. ADG for the entire 11-wk trial was affected (2%) by large group size (0.971 and 0.955 kg d-1 for groups of 18 and 108, respectively; P < 0.05). However, the greatest effect on ADG was observed during the first 2 wk following grouping (0.919 and 0.833 kg d-1 for groups of 18 and 108, respectively; P < 0.001). There were no significant effects due to group size on ADFI, feed efficiency, variability in final BW within a pen, carcass traits or mortality and morbidity (P > 0.05). In summary, the overall productivity and aggression at grouping did not differ substantially between group sizes of 18 and 108 pigs pen-1.

Phosphorus excretion may have a major impact on the environment if it is not managed properly. The success of management strategies for reducing P excretion of pigs is dependent partly on more accurate estimates of P requirements, specifically digestible instead of total P requirements. Performance and metabolism studies were conducted to determine digestible P requirements of grower pigs based on performance, plasma and bone P, and P excretion and retention variables, using 200 pigs (23 ± 0.9 kg) and 20 barrows (54 ± 3.1 kg), respectively. Pigs were fed one of five concentrations of dietary digestible P (0.19, 0.24, 0.33, 0.35, and 0.38%). Increasing digestible P quadratically increased average daily gain (ADG) (P < 0.01), feed intake (P < 0.05), and feed efficiency (P < 0.001). Barrows had a higher ADG than gilts (0.890 vs. 0.838 kg d-1; P < 0.05); however, digestible P requirement was higher for gilts than for barrows (6.92 vs. 6.17 g d-1 or 0.36 vs. 0.32% in diet; P < 0.05). In barrows, increasing digestible P intake quadratically increased P in plasma and urine (P < 0.01), and linearly increased P in faeces (P < 0.01), suggesting that P excretion depends on excess P intake. Using regression analysis, digestible P requirements were 6.45 g d-1 with ADG, 7.46 g d-1 with bone P, 6.01 g d-1 with plasma P, 3.61 g d-1 with urinary P, 5.86 g d-1 with retained P, and 5.11 g d-1 with retained N. Feeding P closer to pig requirements will reduce P excretion. Key words: Phosphorus, requirement, pig
