Abstract Feed cost and excess nutrients excretion are threatening the swine industry. Moderately low protein (MLP) diets are less expensive and reduce the nitrogen excretion, but they may have negative influence on growth performance of pigs. The aim of current study was to investigate the effect of MLP diets supplemented with branched-chain amino acids (BCAA; leucine, isoleucine and valine) higher than Nutrients Requirements of Swine (NRC) recommendation on the growth performance of nursery pigs. Forty-eight weaned barrows at 3 weeks of age were weighed, individually housed and randomly assigned to 6 dietary treatments including: 1) PCON: 20% crude protein (CP), 2) NCON: 14% CP; 3) C25: NCON+ limiting amino acids (LAA, i.e. lysine, methionine, threonine, and tryptophan) 25% more than NRC levels, 4) C50: NCON+LAA 50% higher than NRC recommendations; 5) CB25: NCON + (LAA+BCAA) 25% more than NRC; 6) CB50: NCON + (LAA+BCAA) 50% higher than NRC. The data were analyzed with univariate GLM with Tukey’s post-hoc test (SPSS®). The CB50 had higher final body weight, average daily gain, average daily water intake and average daily feed intake than C50 with the latter tended to be higher than NCON. Average daily feed intake, average daily gain and gain to feed ratio tended to be greater for CB25 and CB50 relative to C25 and C50, respectively. Compared to C50, CB50 improved the mean and cumulative feed intake in all the weeks. CB50 also tended to improve the body weight gain and gain: feed in week 2 relative to C50. In conclusion, supplementing MLP diets with limiting amino acid at 25% or 50% higher than NRC recommendations was failed to recover the negative effects of these diets on growth performance. Adding BCAA more than NRC levels to MLP diets improved the growth performance with the effects of added BCAA level being negligible.

AbstractThe aim of this study was to investigate whether supplementing branched-chain amino acids (AA) (BCAA) along with a reduced-protein diet increases piglet growth, and whether elevated feed intake and muscle growth-promoting effect contribute to this improvement. In Expt 1, twenty-eight weanling piglets were randomly fed one of the following four diets: a positive control (PC) diet, a reduced-protein negative control (NC) diet, an NC diet supplemented with BCAA to the same levels as in the PC diet (test 1 (T1)) and an NC diet supplemented with a 2-fold dose of BCAA in T1 diet (test 2 (T2)) for 28 d. In Expt 2, twenty-one weanling piglets were randomly assigned to NC, T1 and pair-fed T1 (P) groups. NC and T1 diets were the same as in Expt 1, whereas piglets in the P group were individually pair-fed with the NC group. In Expt 1, the NC group had reduced piglet growth and feed intake compared with the PC group, which were restored in T1 and T2 groups, but no differences were detected between T1 and T2 groups. In Expt 2, T1 and P groups showed increases in growth and mass of some muscles compared with the NC group. Increased feed intake after BCAA supplementation was associated with increased mRNA expressions of agouti-related peptide and co-express neuropeptide Y (NPY) and phosphorylation of mammalian target of rapamycin (mTOR) and ribosomal protein S6 kinase 1 (S6K1), as well as decreased mRNA expressions of melanocortin-4 receptor and cocaine- and amphetamine-regulated transcript and phosphorylation of eukaryotic initiation factor 2α in the hypothalamus. No differences were observed among PC, T1 and T2 groups except for higher NPY mRNA expression in the T2 group than in the PC group (Expt 1). Phosphorylation of mTOR and S6K1 in muscle was enhanced after BCAA supplementation, which was independent of change in feed intake (Expt 2). In conclusion, supplementing BCAA to reduced-protein diets increases feed intake and muscle mass, and contributes to better growth performance in piglets.

This study was carried out to evaluate the feeding effect of high yielding fodders (HYF) on feed intake and growth performance of growing Hilly Brown Bengal (HBB) goat. For this purpose, a feeding trail was conducted with 16 growing HBB kids (4 to 5 months) by dividing equally in four groups having four replicates for a period of 75 days. The goats in group T0 (control) received natural grass along with 101.30g concentrates and adlibitum cowpea hay, whereas in group T1, T2 and T3, only natural grass was replaced by BLRI Napier 3, BLRI Napier 4 and Ruzi fodder, respectively. Total dry matter intake (DMI), roughages DMI, crude protein intake (CP), body weight gain (kg), average daily gain (g) and forth night body weight gain (g/day) were studied. Results revealed that, DMI (288.39, 285.71, 293.48 and 301.35 g/day in group T0, T1, T2 and T3, respectively), body weight gain (3.60, 3.74, 3.73 and 3.77 kg in group T0, T1, T2 and T3, respectively), average daily gain (47.32, 49.16, 49.12 and 48.92 g in group T0, T1, T2 and T3, respectively) and feed conversion ratio (6.2, 5.9, 6.0 and 6.1 in group T0, T1, T2 and T3, respectively) of HBB kids were not differed significantly (P>0.05) for all the treatment groups. The DMI from roughages (196.2, 193.5, 201.3 and 209.2 g/day in group T0, T1, T2 and T3, respectively) and CP intake (38.7, 42.1, 48.3 and 38.8 g/day in group T0, T1, T2 and T3, respectively) were significantly varied (P<0.05), while highest CP intake was found in the treatment group T2. Forthnight body weight (g/day) was not significantly (P>0.05) gained with feeding of HYF for all the treatment groups. From this study, it can be concluded that, growing HBB kids could equally be supplied with either BLRI Napier 3 or BLRI Napier 4 or Ruzi fodder in addition to ad libitum cowpea hay for better voluntary feed intake and growth.

Abstract Branched chain amino acids (BCAA), valine (Val), isoleucine (Ile) and leucine (Leu) share the same metabolic pathways. An excess of Leu stimulates the catabolism of Val and Ile that may lead to a decrease in piglet growth performance. The objective of this study is to quantify the response of piglets to dietary Val and the influence of Leu and Ile on this response through a meta-analysis approach. A total of 16 articles published between 2001 and 2018, including 23 experiments and 126 treatments were used. Multiple regression models were fitted with the MIXED procedure of Minitab software with the random effect of the experiment. The Y variables were Average Daily Gain (ADG), Average Daily Feed Intake (ADFI) and Feed Conversion Ratio (FCR). The main X variable was the Standardized Ileal Digestible Val (ValSID) and the other ones were Leu (LeuSID) and Ile (IleSID). The response of ADG, ADFI and FCR to ValSID was curvilinear (P&lt; 0.001: ADG, R2 = 0.93%; ADFI, R2= 0.97%; FCR, R2=0.93%). Results showed that increasing dietary LeuSID reduced ADG and ADFI (P&lt; 0.05) but also that the response of piglets to ValSID was stronger in high LeuSID diet (P &lt; 0.05; Interaction ValSIDxLeuSID; ADG and ADFI). Based on these models, increasing dietary ValSID from 7 to 8.5g/kg generates in wheat-based diets (10 g /kg of LeuSID) an improvement of ADG of 4.7% and ADFI of 2.5% compared to 7.4% for ADG and 5.2% for ADFI in corn-based diets (14 g/ kg of LeuSID). The response of ADG, ADFI and FCR to ValSID was not modified by IleSID. This study showed that ADG, ADFI and FCR are improved with increasing dietary Val and this effect was modulated by dietary Leu content except for FCR. Results can help piglet nutritionists to optimize dietary Val levels based on other BCAA content.

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

The objective of the study was to determine the interaction of pen enrichment and sex on growth performance and blood metabolite concentrations of Windsnyer pigs. Forty-eight growing Windsnyer pigs of both sexes, with an average initial body weight of 21.6 (±9.01) kg were used. Daily feed intake and weekly body weights for each pen were measured. Blood was collected at the end of the experiment. Pen environment did not affect average daily feed intake (ADFI) and average daily gain. There was a pen environment and sex interaction on ADFI. Females in barren pens had higher ADFI than enriched females but ADFI in barren and enriched pens was similar for male pigs. Pigs in enriched environment were more efficient in converting feed into body weight than those in barren environment. There was an interaction of pen environment and sex on glucose, blood urea nitrogen (BUN), and alkaline phosphatase. Enriched males had higher albumin than males in barren environment. Enriched females had higher BUN than females in barren environment. It was concluded that enriched Windsnyer pigs housed at a density of 0.39 m2 per pig, particularly females, perform better than those in barren environments.

Effect Of Feeding

Fumonisin contamination in corn is an emerging issue in animal feed production. Fumonisin disrupts the metabolism of sphingolipids and reduces growth performance. This experiment was conducted to determine the effect of feeding fumonisin-contaminated corn on growth performance and sphinganine (SA) to sphingosine (SO) ratios of 9 to 28 kg pigs. A total of 350 pigs, were used with 5 pigs/pen and 14 pens/treatment. Dietary treatments contained fumonisin-contaminated corn (50 mg/kg of fumonisin B1 + B2) blended with low fumonisin corn (10 mg/kg of fumonisin B1 + B2) to provide dietary fumonisin concentrations of 7.2, 14.7, 21.9, 32.7, and 35.1 mg/kg. From day 0 to 28, increasing fumonisin concentration decreased (linear, p < 0.001) average daily gain, average daily feed intake (linear, p = 0.055), and gain:feed ratio (linear, p = 0.016). Although these response criteria tested linear, the greatest reduction in performance was in pigs fed with 32.7 and 35.1 mg/kg of fumonisin (B1 + B2). Increasing fumonisin concentration increased the serum SA:SO ratio (linear, p < 0.001) on day 14 and 28. In summary, for 9 to 28 kg nursery pigs, increasing fumonisin linearly decreased average daily gain and gain:feed ratio. However, despite the linear response, diets containing up to 21.9 mg/kg of fumonisin did not have as dramatic a decrease in growth performance as those fed more than 32.7 mg/kg. Further research is warranted to determine the effect of fumonisin concentrations between 21.9 and 32.7 mg/kg.

The objective of this work was to evaluate performance, efficiency parameters and phenotypic correlations among measurements of energy efficiency of Nellore cattle selected for post weaning weight and classified according to residual feed intake, calculated by the difference between observed and predicted intake, based on average metabolic body weight and average daily gain. Thus, animals were classified within three groups: high (> mean + 0.5 standard deviation, less efficient); medium (±0.5 standard deviation of the mean); and low (< mean - 0.5 standard deviation, more efficient) residual feed intake. No differences were observed at initial and final body weights, average daily gain and dry matter intake among groups. Animals with low residual feed intake also had greater feed efficiency, feed conversion and partial efficiency of growth and did not differ from the other animals regarding to relative growth rate and Kleiber ratio. Residual feed intake was significantly correlated to feed efficiency (-0.25), feed conversion (0.25), partial efficiency of growth (-0.37) and dry matter intake (0.16) but it did not present significant correlation with body weight (0.04), average daily gain (-0.02), relative growth rate (-0.03) and Kleiber ratio (-0.05). Significant correlations were found between feed conversion and initial body weight (0.34) and average daily gain (-0.46). Partial efficiency of growth presented significant correlation with all other efficiency parameters analyzed. Residual feed intake has high potential in productive efficiency, when compared to the other energy efficiency measurements, being independent of growth and size of the animals.

The effect of abomasal infusion of glucose (120 kJ/d per kg body weight (BW)0·75, 758 mmol/d) on urea production, plasma alanine-N flux rate and the conversion of alanine-N to urea was studied in sheep offered a low-N diet at limited energy intake (500 kJ/d per kg BW0·75), based on hay and grass pellets. Glucose provision reduced urinary N (P= 0·040) and urea (P= 0·009) elimination but this was offset by poorer N digestibility. Urea-N production was significantly reduced (822v. 619 mmol/d,P= 0·024) by glucose while plasma alanine-N flux rate was elevated (295v. 342 mmol/d,P= 0·011). The quantity of urea-N derived from alanine tended to be decreased by glucose (127v. 95 mmol/d) but the fraction of urea production from alanine was unaltered (15 %). Plasma urea and alanine concentrations (plus those of the branched chain amino acids) decreased in response to exogenous glucose, an effect probably related to enhanced anabolic usage of amino acids and lowered urea production.

The objective of this work was to study the lamb’s growth, the carcass yield and composition and the importance of main organs of Berber lambs slaughtered at 4 or 6 months. The study concerned 40 lambs reared under motherhood. Lambs of the first group were slaughtered at the age of 4 months (4M) and the second at 6 months (6M). Slaughter body weights (BW), hot and cold carcass weights and organs were recorded. The carcass was cut out and dissected. The average BW at birth was 4.14 + 0.506 kg while the BW at slaughter was 22.86 kg + 3.40 and 31.51 + 3.50 kg for 4M and 6M groups, respectively. The average daily gain were 172 and 164g for 4M and 6M groups, respectively. Therefore, during 2months the lambs of 6M group gained 8.67 kg in BW. The carcasses were heavier for 6M than 4M. The carcass commercial yields were 42% and 45% for 4M and 6M groups, respectively, resulting in 4.1 kg gain of meat during 2 months. The tissular (muscle, fat and bone) and the regional (leg, shoulder …) carcass composition did not differ among groups. All organs were heavier for 6M than 4M; however, their proportion in the empty body weight were variables. The BWand carcass gain at six months are encouraging to prolong the lamb’s slaughter age without carcass composition difference given the similar fat proportion in the carcass of both groups.

Abstract Lactose is an effective carbohydrate source for nursery pigs. Weaning age could influence needs for lactose. Weaning ages can vary among producers depending on preferred management programs. This study aimed to evaluate optimum levels of lactose for pigs at 7 kg BW weaned at different ages. A total of 1,632 pigs were weaned at d21 (d 21.2 ± 1.3) or d25 (d 24.6 ± 1.1). Pigs had a common diet until they reach 7 kg BW. Within a same weaning age group, when pigs reached 7 kg body weight, they were allotted to 4 dietary treatments with 6, 9, 12, and 15% lactose. Feed intake and BW were measured after 10d feeding when pigs reached 11 kg BW. Data were analyzed using the MIXED procedure of SAS for a slope ratio analysis to test effects of lactose levels on growth performance of pigs influenced by their weaning ages. Pigs weaned at d21 had Phase 1 for 11 days whereas pigs weaned at d 25 had Phase 1 for 2 days to reach 7 kg BW. According to the slope ratio analysis, as increasing lactose intake, ADG of pigs weaned at d21 responded greater (P &lt; 0.05, 68.5%) than growth of pigs weaned at d25. There was no change of slope in feed intake of pigs weaned at d 25 by increasing lactose intake. However, G:F of pigs weaned at d 25 responded greater (P &lt; 0.05, 250%) than G:F of pigs weaned at d21. In conclusion, pigs weaned at d21 grew faster from 7 to 11 kg BW as lactose intake increased compared with pigs weaned at d25 potentially because pigs weaned at d21 had an extended time for adaptation and recovery from weaning stress until they reached 7 kg BW.
