Abstract During the last century, the emission of nitrous oxide (N2O) from the livestock sector increased significantly. N2O is a greenhouse gas with 298-fold higher global warming potential (GWP) than CO2. Pigs accounted for about 26% of N2O emissions. The formation of N2O occurs through nitrification and denitrification processes in manure. This study aimed to estimate N2O production in the manure of growing-finishing pigs by using our experimental data in the model. The associative effects of dietary mustard and grapeseed oil cakes (MxG), as an alternative for sunflower meal (SFM), on performance and efficiency traits were also determined. Forty growing-finishing pigs were randomly allocated in two groups (2 replicates per group) fed two diets: C diet (based on SFM, 15 wt) and E diet (based on M and G mixture, 7:8 wt:wt). Our model includes as initial input data: body weight (BW), feed intake, nitrogen intake, dietary dry matter, and fibre intake. Using literature prediction equations, including total nitrogen output (TNO) as the main parameter, we established N2O production expressed as equivalent CO2 (E-CO2). A decline with 3% for BW (P=0.44), respectively 9.0% for average daily gain (ADG, P=0.21) in pigs given MxG was recorded. Correlated with growth parameters, efficiency traits (feed intake, feed: gain ratio, N and fibre intake) were decreased as well (P>0.05). Dietary addition of MxG led to a 5% lower level of N2O production in manure. The reduction of TNO was not significant (<7.14% in the E diet compared to the C diet). In our trial, a relatively low N intake percentage is retained in the pigs body (35.56% in the C group and 35.98% in the E group, P>0.05). Based on these results, we conclude that the inclusion of 15% MxG mixture in pigs diets, although slightly declining growth parameters, is a valuable nutritional solution by their contribution to lowering N2O and N output in the manure.

This study focused on using vegetable leaves for rabbit feeding. Rabbit fed with leaves of Abelmoschus esculentus, Corchorus olitorius, Ipomea batatas, Vigna unguiculata, Solanum melongena showed positive growth and high feed intake, while rabbits fed with leaves of Amaranthus hybridus, Hibiscus sabdariffa, Manihot esculenta, Celosia argentea, Myrianthus arboreus, Basella alba, Talinum triangulare, Colocasia esculenta showed low feed intake and weight loss. The digestibility of treatments supplemented with concentrate was better than that of the diet without fodder. Feed intake (157.62 g / day) and average weight (2081.87g) of rabbits fed with leaves of Ipomea batatas, were the highest while average daily gain (24.38 - 27.29 g/day) remained similar. The feed conversion ratio of the control treatment (3.51) was better than those obtained for treatments supplemented with concentrate (5.31 - 5.71). Urea and creatinine values were similar in all groups. Blood glucose (0.94 ± 0.04 g/L) and total protein (68.40 ± 0.14 g/L) of rabbit fed with leaves of Solanum melongena were the highest. Total cholesterol of rabbit fed with leaves of Ipomea batatas and control diet were the highest. The blood triglycerides of rabbit fed with control diet was the highest and differed to other treatments (p < 0.05).

Abstract It was hypothesized that hybrid rye may replace corn in diets for growing and finishing pigs without impacting growth performance, carcass characteristics, or meat quality. A total of 128 pigs (23.69 ± 2.51 kg) were allotted to 4 treatments with 8 replicate pens per treatment. Phase 1 and 2 diets were fed for 35 d each and phase 3 diets were fed for 27 d. Within each phase, pigs were fed a control corn and soybean meal diet or a diet in which 33, 66, or 100% of the corn in the control diet was replaced with hybrid rye. Average daily gain (ADG) and average daily feed intake (ADFI) decreased (linear, P &lt; 0.05) in phase 1 with increased dietary inclusion of hybrid rye. In phase 3, gain:feed (G:F) increased and then decreased (quadratic, P &lt; 0.05) with more hybrid rye in the diet. Overall ADG, ADFI, and G:F did not differ among treatments. Diet did not impact most carcass traits, but loin (visual) and backfat (instrumental L*) color were paler (linear, P &lt; 0.05) with greater inclusion of hybrid rye in the diet. Organ weights increased (linear, P &lt; 0.05) with increased dietary hybrid rye. In conclusion, pigs fed hybrid rye consumed less feed in phase 1, resulting in reduced ADG, but growth performance for the entire growing-finishing period did not differ among treatments. Hybrid rye may replace all the corn in growing and finishing pig diets without diminishing growth performance or carcass quality, but feed intake may be reduced at high inclusion rates.

The aim of this study was to evaluate the influence of vitamin and β-glucan supplementations on growth performance of growing-finishing pigs in Ben Tre province. A total of 36 post-weaned piglets (Duroc x Yorkshire-Landrace) with the initial live weight of 17.42 kg±0.26, was allotted into 3 treatments and 4 replications in a completely randomized design. There were three diets, including basal diet (BD) without any addition of β-glucan or vitamin (diet CT), the BD supplemented with vitamin (diet Vit) and the BD supplemented with β-glucan (diet Glu). The results on growth parameters indicated that final live weight (kg), weight gain (kg), and average daily gain (g/head/day) of pigs in the experimental diets were significantly higher (P<0.01) than those in the control treatment. FCR was lowest in Glu and highest in the control (P<0.01). Financial benefit based on feed and veterinary expenses was higher in the vitamin and β-glucan supplement diets than that of the control from 15.74% to 18.98%, respectively.

Linear Relationships

High ambient temperature (AT) is a major constraint on efficiency of farming in pig production. Results of reported studies assessing the influences of high AT on pig performance are highly variable, particularly in pigs with different body weight (BW). Therefore, a meta-analysis from ISI Web of Science and PubMed was operated to explain variations of average daily feed intake (ADFI) and average daily gain (ADG) in the reports across literatures during high AT in growing or finishing pigs. Pigs were divided to three BW categories as LOW (46 to 65 kg), MED (65< to 85 kg), and HGH (85< kg). The significant effect of AT on ADG were observed in LOW, MED, and HGH categories. The analysis of variance (ANOVA) for multiple linear regression shows significance of linear relationships between both ADG and ADFI, and AT and BW as: ADGLOW= 1260-19.9*AT+2.09*BW, ADGMED= 1546-22.5*AT-0.88*W, ADGHGH= 1893-31.9*AT-2.40*BW, ADFILOW= 1756-35.0*AT+24.6*BW, ADFIMED= 2793-49.6*AT+12.5*BW, and ADFIHGH= 4172-59.0*AT+0.74*BW. The significant effect of temperature on gain to feed ratio (G:F) was observed in LOW and HGH categories. The ANOVA for multiple regression revealed evidence on high significance of linear relationships between G:F and AT: G:FLOW =0.80+0.02*AT+0.02*BW, G:FMED= 0.95+0.02*AT+0.02*BW, and G:FHGH= 0.78+0.05*AT+0.01*BW. The overall results of mixed model analysis show that the significant interaction between BW and AT means that pigs in heavier category have lower G:F when temperature increases. In conclusion, high AT linearly decrease the ADG, ADFI, and G:F of growing and finishing pigs.

High-moisture barley (HMB) was ensiled or treated with 1% (wt/wt) liquid sulfur dioxide (SO2). Forty-five weanling pigs were allocated to five dietary treatments for 28 d. Diets consisted of: (1) dry barley, diet mixed every 28 d; (2) ensiled HMB, diet mixed daily; (3) SO2-treated HMB, diet mixed every 28 d; (4) SO2-treated HMB, diet mixed daily; (5) SO2-treated HMB, diet mixed daily and supplemented with thiamin. All diets contained 47% barley on a dry matter (DM) basis. Pigs fed diets 2 and 4 continued on test to 85 kg; diets formulated after 28 d contained 75% barley (DM basis). Feed intake, growth rate and feed:gain ratio were not influenced (P < 0.05) by treatment during the 28-d initial trial. For pigs fed SO2-treated HMB to 85 kg, feed intake and average daily gain were reduced by 9.8 and 9.0%, respectively. SO2 treatment effectively preserved high-moisture barley for 18 d at 16 °C; however, 61% of the dietary thiamin was destroyed by 7 d after diet mixing. Pigs fed diet 4 were thiamin depleted at slaughter; with a 38.5% higher erythrocyte thamin pyrophosphate effect, an 83% incidence of cardiac hypertrophy and thiamin levels in meat reduced to 7.6% of that present in the meat of pigs fed untreated HMB. Destruction of dietary thiamin appears to have been the primary factor responsible for reduced animal performance. Reduced ration palatability and toxicological effects on the digestive tract due to 75% SO2 treated grain in the diet (DM basis) may have also contributed to the reduced performance of growing-finishing pigs.

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 Two experiments were conducted to determine the effects of increasing levels of soybean meal (SBM) replacing feed grade amino acids in corn or corn-dried distillers grains with solubles (DDGS)-based diets on growth performance of late finishing pigs. In both experiments, there were 22 to 27 pigs per pen and 14 pens per treatment. Average length of the experiments was 35 (Exp. 1) and 29 days (Exp. 2). Diets were balanced to contain 0.70% SID Lys and 2,667 or 2,610 kcal NE/kg for Exp. 1 and 2, respectively. Minimum amino acid ratios relative to Lys were: Ile, 55; Met&Cys, 60; Thr, 65; Trp, 19.5, and Val, 70. Dietary crude protein ranged from 10.1 to 15.2 for Exp. 1 and 13.6 to 19.4 for Exp. 2. The statistical model considered fixed effects of treatment, linear and quadratic contrasts, and random effect of block. In Exp.1, 1,793 pigs (L337×1050, PIC; initially 104.9 ± 1.4 kg) were fed corn-based diets and pens of pigs were assigned to 1 of 5 dietary treatments with increasing SBM from 5 to 20%. Overall, average daily gain (ADG) and gain-to-feed (G:F) increased (linear; P &lt; 0.05) as SBM increased with the greatest improvement observed as SBM increased from 5 to 8.75%, with little improvement thereafter. In Exp. 2, 1,827 pigs (L337×1050, PIC; initially 97.9 ± 1.1 kg) were used in a similar study as Exp. 1, but all diets contained 25% DDGS and SBM levels increased from 0 to 16%. Overall, G:F and final bodyweight of pigs marginally improved (linear and quadratic, respectively; P &lt; 0.10) as SBM increased, with the greatest performance observed when diets contained 8% SBM. These results suggest that increasing SBM up to 8% at the expense of feed grade amino acids in corn or corn-DDGS-based diets improved ADG or G:F in late-finishing pigs.

AbstractNutrient requirements of sows during lactation are related mainly to their milk yield and feed intake, and vary greatly among individuals. In practice, nutrient requirements are generally determined at the population level based on average performance. The objective of the present modeling approach was to explore the variability in nutrient requirements among sows by combining current knowledge about nutrient use with on-farm data available on sows at farrowing [parity, BW, backfat thickness (BT)] and their individual performance (litter size, litter average daily gain, daily sow feed intake) to estimate nutrient requirements. The approach was tested on a database of 1,450 lactations from 2 farms. The effects of farm (A, B), week of lactation (W1: week 1, W2: week 2, W3+: week 3 and beyond), and parity (P1: 1, P2: 2, P3+: 3 and beyond) on sow performance and their nutrient requirements were evaluated. The mean daily ME requirement was strongly correlated with litter growth (R2 = 0.95; P < 0.001) and varied slightly according to sow BW, which influenced the maintenance cost. The mean daily standardized ileal digestible (SID) lysine requirement was influenced by farm, week of lactation, and parity. Variability in SID lysine requirement per kg feed was related mainly to feed intake (R2 = 0.51; P < 0.001) and, to a smaller extent, litter growth (R2 = 0.27; P < 0.001). It was lowest in W1 (7.0 g/kg), greatest in W2 (7.9 g/kg), and intermediate in W3+ (7.5 g/kg; P < 0.001) because milk production increased faster than feed intake capacity did. It was lower for P3+ (6.7 g/kg) and P2 sows (7.3 g/kg) than P1 sows (8.3 g/kg) due to the greater feed intake of multiparous sows. The SID lysine requirement per kg of feed was met for 80% of sows when supplies were 112 and 120% of the mean population requirement on farm A and B, respectively, indicating higher variability in requirements on farm B. Other amino acid and mineral requirements were influenced in the same way as SID lysine. The present modeling approach allows to capture individual variability in the performance of sows and litters according to farm, stage of lactation, and parity. It is an initial step in the development of new types of models able to process historical farm data (e.g., for ex post assessment of nutrient requirements) and real-time data (e.g., to control precision feeding).
