Pig Performance

Tail-biting is a behavioural vice with important welfare, economic and carcass quality implications observed in growing pigs. Fraser (1987) proposed that mineral deficiencies in the diet may be related to tail-biting while Beattie et al (1996) found that tail-biting did not occur in intensive housing when pigs had access to a rooting substrate. This study compared the effects on pig performance and behaviour of increased dietary salt concentration with a negative control (standard diet, no rooting substrate) and a positive control (standard diet, rooting substrate provided).

Abstract Objective was to determine the effects of supplementing corn-soybean meal-based diets with a multi-enzyme on growth performance and apparent total tract digestibility (ATTD) of nutrients in growing pigs. A total of 276 pigs (BW = 33.99 ± 4.3 kg) were housed by sex in 45 pens of 6 or 7 pigs and fed 5 diets (9 pens/diet) in a randomized complete block design. Diets were positive control (PC); and negative control 1 (NC1) or negative control 2 (NC2) without or with multi-enzyme. The multi-enzyme used supplied at least 1,250, 860, 4,600, and 1,000 units of xylanase, β-glucanase, arabinofuranosidase and phytase per kilogram of diet, respectively. The PC was adequate in all nutrients according to NRC (2012) recommendations and had greater digestible P content than NC1 diet or NC2 diet by 0.134 percentage points. The NC1 diet had lower NE and digestible AA content than PC diet by 3%. The NC2 diet had lower NE and digestible AA content than PC diet by 5%. The diets were fed in 4 phases based on BW; Phase 1: 34–50 kg, Phase 2: 50–75 kg, Phase 3: 75–100 kg, and Phase 4: 100–120 kg. Nutrient digestibility was determined at the end of Phase 1. Overall (34–120 kg BW), pigs fed the PC and NC1 diets did not differ in ADG and ADFI. Pigs fed NC2 diet had lower (PPPP > 0.10). Supplemental multi-enzyme increased (P = 0.047) the ATTD of GE for NC2 diet. In conclusion, the NE and digestible AA and P can be lowered by ≤ 5% in multi-enzyme-supplemented diets without effects on growth performance pigs.

Limiting Amino Acids

Individual and group housed crossbred pigs 45 to 105 kg and 65 to 95 kg in experiments 1 and 2, respectively, were given basal diets with L-threonine 0.6, 1.2 and 1.8 g/kg. Positive and negative control diets contained total threonine 5.7 and 4.5 g/kg, respectively. To prevent other amino acids being limiting, the negative control diet was supplemented with lysine, methionine, tryptophan, isoleucine, histidine and valine. The positive control diet was supplemented with lysine and methionine. The requirement for total threonine of growing-finishing pigs for maximum growth performance was about 5.6 g/kg in a diet containing net energy 9.4 MJ/kg. This figure corresponds with about 4.7 g/kg apparent faecal digestible threonine and 4.3 apparent ileal digestible threonine. There was no difference between the growing and the finishing pigs. The requirement for ileal digestible threonine, relative to ileal digestible lysine requirement, was about 64%. It is concluded that dietary protein can be reduced by 2 percentage units without any adverse effect on growth performance, if limiting amino acids are sufficiently supplemented.

Low Energy Diet

A total of 90 finishing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 50.02 ± 1.78 kg were used in a 10 wk experiment. The pigs were distributed into three dietary treatments replicated six times with five pigs (two barrows and three gilts) per pen. The treatment diets were a positive control (PC; high-energy diet), a negative control (NC; low-energy diet), and an NC + 0.05% ferritin diet (TRT1). The supplementation of ferritin in a low-energy diet tended (P = 0.06) to increase the BW at week 5 compared with pigs fed low-energy diets without ferritin. At week 5 and overall period, the gain-to-feed ratio of pigs fed high-energy diets was higher (P < 0.05) compared with pigs fed low-energy diets. The pigs receiving a ferritin-supplemented diet had a comparable growth performance to pigs fed high-energy diets. At week 10, fecal Lactobacilli counts of pigs fed high-energy diets were higher (P < 0.05) compared with pigs fed low-energy diets. The supplementation of low-energy diets with ferritin resulted in comparable growth performance to pigs fed high-energy diets and had no adverse effect on digestibility and fecal gas emissions. Thus, it seems beneficial to include ferritin in low-energy diets of finishing pigs.

Abstract Background and aims: Cardiovascular diseases are widespread and causes many deaths in the world. The concentration of acute phase protein: C-reactive protein (CRP) and fibrinogen will rise dramatically when inflammation happens, which that can be used as an early marker of cardiovascular disease risk. Tempeh gembus contains fiber, unsaturated fatty acids and isoflavones are believed to reduce the inflammatory reaction. The aim of the study was to determinate the effect of tempeh gembus variations to levels of hcCRP and levels of fibrinogen of Sprague Dawley rats with atherogenic diet. Material and methods: This study was quasi-experimental with posttest only randomized control group design using 35 Sprague Dawley mice. The rats were randomized into 5 groups: negative control group given the standard diet, the positive control group given standard diet and atherogenic diet, and three treatment groups were given the standard diet, atherogenic diet and variation of tempeh gembus (tempeh gembus, heated tempeh gembus and tempeh gembus with bromelain enzyme) for 28 days. Serum levels of hsCRP and fibrinogen examined using ELISA (Enzyme-linked Immunosorbent Assay). Results and conclusions: The administration of tempeh gembus with bromelain enzyme is the most effective treatment for hsCRP serum level indicated a significant difference (p=0.028) between the negative control group, positive control group and first group with the third group. Fibrinogen serum levels showed significant differences in all treatment groups (p =0.042), administration of tempeh gembus with bromelain enzyme is the most effective treatment is shown by a significant difference between the negative control group and the positive control group with third group. The administration of tempeh gembus with bromelain enzyme for 28 days can reduce the serum levels of hsCRP and fibrinogen on rats significantly.

The effect of increasing the dietary crude protein (CP) level on the growth performance and carcass characteristics of Large White pigs reared in Guadeloupe under tropical climatic conditions was determined. Test animals included 32 females and 32 barrows, each weighing about 24 kg initially. They were individually fed one of four test diets based on corn and soybean-oil meal containing 12, 16, 20, and 24% CP, respectively. The 12 and 16% CP diets were supplemented with synthetic L-lysine hydrochloride. The animals were slaughtered at 95 kg liveweight. On the basis of maximum daily gain and minimum feed conversion ratio, the best level of CP among the various levels compared was 16% for the growing pigs (from 24 to 60 kg liveweight) and 12% for the finishing pigs (from 60 kg to 95 kg liveweight). There was no significant effect of sex on growth performance, but the feed conversion ratio of the finishing females was 8% better than that of the barrows. As the dietary CP level increased, dressing percentage and backfat thickness decreased linearly (P < 0.05). Females were significantly leaner (P < 0.05) than barrows. Further work is needed to determine the optimum level of CP for finishing pigs.

Abstract The objective of this experiment was to evaluate the optimal dosage of phytase fed to growing-finishing pigs. One hundred and twenty barrows, 71 d old and initial body weight 25.16 ± 2.80kg, were distributed in 40 pens according to a randomized complete block design and assigned to 5 treatments: 1. Positive control: diet formulated to meet or exceed the nutrient requirement of pigs (PC); 2. Negative control: PC diets formulated with 0,11% lower Ca and 0,13% lower available P (NC); 3. NC + 1,500 FYT of phytase; 4. NC + 3,000 FYT of phytase; 5. NC +4,500 FYT of phytase. The corn-soybean meal-based diets were formulated to be iso-nutrient and isoenergetic, except for Ca and av. P. The 4 diets were formulated according to a growing I (71-94 days of age), growing II (95-115d), finishing I (116-143 d) and finishing II (144-156 d) phases. Carcass traits were measured and submitted to the European Carcass Classification (SEUROP). Performance and carcass data were submitted to ANOVA, and regression analysis. There was a quadratic effect on FCR (P&lt; 0.05) in growing I phase,; better FCR (quadratic, P&lt; 0.05) on finishing II to 1,500 and 3,000 FYT (5.56 and 0.35%, respectively); an increase of 5.43 and 1.52% DWG in finishing II (quadratic, P&lt; 0.05) and a reduced 6.60% to 4,500FYT; an improvement the total DWG and final weight (quadratic, P&lt; 0.05) in 6.19 and 4.52%, and 5.27 and 3.57%, for 1,500 and 3,000 FYT, respectively. Phytase supplementation did not improve Carcass weight (P &gt;0.05). The animals fed with 4,500 FYT diet had more carcasses classified as E (between 55–60% lean meat-SEUROP) compared other groups. Doses between 1,500 and 3,000 FYT improve FCR, DWG and final LW of growing and finishing pigs.

Spermatogenesis can be affected by oxidative stress produced by the increasing of pro-inflammatory adipokines because of high fat diet.The spermatogenesis cells damaged can be prevented with natural substance such as red pitaya (Hylocereus polyrhizus). This study aims to analyze effect of Hylocereus polyrhizus extract on rat’s spermatogenesis cells number that induced by high fat diet. This study had used true-experiment design. 30 rats were divided into 5 groups. Groups 1 to 4 had done treatment for 52 days and group 5 treatment for 104 days. Group 1 Negative control (K1) administered with standard diet, group 2 Positive control (K2) had administered quail egg 10ml/KgBW, group 3 Experiment 1 (P1) had administered quail egg polyrhyzus  10ml/Kg BW and with simvastatin 0,72mg/day, group 4 Experiment 2 (P2) had administered quail egg 10ml/KgBW and wth Hylocereus polyrhizus extract 60mg/day in 52 days, and group 5 Experiment 3 (P3) had administered quail egg 10ml/KgBW and with Hylocereus polyrhizus extract 60mg/day in 104 days. Data were analyzed by One Way ANOVA and continued with Post Hoc Tukey’s HSD (P-Value=0,05) for 52 day groups. Group P1 and P2 showed repairing effect and increasing spermatocytes and spermatids (p.000<0,05) compared to group K2. Group P2 had more spermatids and spermatocytes than group P1 (p.000<0,05). Group P2 52 days’ spermatid cells equalled to group P3 104 days (p.469>0,05). Hylocereus polyrhizus extract not only had mechanism like simvastatin but also contained antioxidant, and a long-term treatment had not proven bad effect to spermatogenesis cells.  Conclusion. Hylocereus polyrhizus extract 60mg/day can repair and increase spermatogenesis cells induced with high fat diet.

Abstract A total of 320 barrows (DNA 200×400, initially 11.3 ± 0.65 kg BW) were used in a 21-d growth trial evaluating the effects of feeding Trp biomass (CJ America-Bio, Downers Grove, IL) as a source of Trp on nursery pig performance. Pigs were weaned at approximately 21 d of age, placed in pens based on initial BW, and fed a common diet. On d 21 after weaning, pigs were weighed and pens were allotted to 1 of 4 dietary treatments with 5 pigs/pen and 16 replicates/treatment. Dietary treatments included a negative control (16% SID Trp:Lys), positive control (21% SID Trp:Lys from crystalline L-Trp), or diets containing Trp biomass to provide 21 or 23.5% SID Trp:Lys (included at 0.104 or 0.156% of the diet, respectively). Diets were corn-soybean meal based and contained 1.25% SID Lys with other AA set to meet or exceed NRC (2012) requirement estimates. The Trp biomass contained 69% Trp. Growth data were analyzed as a randomized complete block design using PROC GLIMMIX of SAS with pen as the experimental unit. Overall (d 0 to 21) pigs fed 21% Trp from L-Trp or Trp biomass had increased (P < 0.05) ADG compared to the control, with pigs fed the 23.5% SID Trp biomass intermediate. Pigs fed the 21% Trp from Trp biomass had improved (P < 0.05) G:F compared to the control with others intermediate. In conclusion, Trp biomass is a viable alternative to crystalline Trp, but further evaluation at higher inclusion levels is needed.

Abstract A total of 300 weanling pigs (Line 400 × 200, DNA, Columbus, NE, initially 4.83 kg) were used in a 46-d trial to evaluate the effects of different nutritional strategies to replace pharmacological levels of Zn, provided by zinc oxide (ZnO), in nursery diets on growth performance and fecal dry matter (DM). Six treatments with 10 replicate pens per treatment and 5 pigs per pen were used. Diets consisted of: 1) Positive control (ZnO providing 3,000 mg/kg added Zn from d 0 to 7 and 2,000 mg/kg added Zn from d 8 to 25 and 21% crude protein, CP); 2) Negative control (NC; no added ZnO); 3) NC plus 1.2% Na Diformate; 4) NC with 4% coarse ground wheat bran; 5) NC but formulated to 18% CP); and 6) The combination of NC with 18% CP, 1.2% Na Diformate, and 4% coarse ground wheat bran. The diets formulated to 18% CP contained 1.2% standardized ileal digestible (SID) Lys from day 0 to 25 whereas the 21% CP diets contained 1.4% SID Lys from day 0 to 7 and 1.35% SID Lys from d 7 to 25. From d 25 to 46, all pigs were fed a common diet. From d 0 to 7, no differences in any variables were observed between treatments. From d 7 to 25, pigs fed the diet with added ZnO had greater (P &lt; 0.01) ADG and ADFI than all other treatments. Pigs fed the diet formulated to 18% CP had decreased (P &lt; 0.01) ADG compared with pigs fed the other diets. From d 25 to 46, no previous treatment effects on ADG or G:F were observed. Overall (day 0 to 46), pigs fed the diet with added ZnO from d 0 to 25 had greater (P &lt; 0.01) ADG, ADFI, and final BW than pigs fed added Na Diformate, or 4% coarse ground wheat bran, or with the 18% CP diet, with pigs fed the combination of the additives intermediate. There was no evidence for differences in overall G:F. Pigs fed the NC diet had the lowest fecal DM and highest fecal scores (P &lt; 0.05) indicating the greatest incidence of loose stools. Pigs fed added ZnO had greater fecal DM than pigs fed the NC, 4% added wheat bran, or 18% CP diets, with pigs fed the combination of additives intermediate (P &lt; 0.01). These results suggest that adding pharmacological levels of Zn from ZnO improves nursery pig performance and increases DM content of feces when compared with pigs fed diets with either, Na Diformate, 4% course wheat bran, or 18% CP alone. However, a combination of all 3 alternatives appeared to be additive and partially restore growth performance similar to adding pharmacological levels of Zn.
