The Impact

Abstract The addition of a sensory additive to sow diets during the summer improved feed intake during lactation, and litter performance. The aim of this study was to evaluate the impact of the sensory additive on sow lactation performance during cooler temperatures. Three consecutive groups (n = 61 total) of sows were farrowed during winter (October, December and January). Sows were weighed, and back fat depth was measured, at 110 d of gestation prior to entering the lactation room, and again at weaning. The sows were sorted by parity, and then allotted by BW at d 110 to Control or 0.075% sensory additive (Luctamax® SowVive, Lucta S.A., Spain). Experimental diets were offered upon entry to the lactation room and fed through weaning. Feed disappearance was recorded every three days. Sows were fed 2.72 kg/head/day until farrowing, and then allowed to eat ad libitum from 24 hours post-farrowing until weaning. Data were analyzed using the PROC MIXED procedure of SAS as an RCBD with treatment as the fixed effect and group as a random effect. No differences were observed on sows feed intake (P > 0.4), 10th rib backfat thickness change (P = 0.632) and body weight change from d 110 of gestation to weaning (P = 0.65, Table 1). Sows fed the sensory additive lowered preweaning mortality by 4.9% (P = 0.051), and weaned an additional 1.42 piglets (P = 0.026) with similar weaning weights (P = 0.86) when compared to control. In conclusion, in the current study, lactation diets supplemented with a sensory additive improved litter performance and helped maintain sow body condition.

Abstract Sow feed intake during lactation is crucial to the maintenance of sow body condition, milk production, and litter performance. Loss of body weight or condition during this time could compromise future reproductive performance. Two groups (n = 52 total) of breeding age gilts and sows were used to evaluate whether a sensory additive would improve intake during the lactation period. Gilts/Sows were weighed, and back fat depth was measured, at 110 d of gestation prior to entering the lactation room, and again at weaning. The sows were sorted by parity and then allotted by BW at d 110 to Control or 0.075% sensory additive (Luctamax® SowVive, Lucta S.A., Barcelona, Spain). Experimental lactation diets were offered upon entry to the lactation room and fed through weaning. During this time feed was weighed back every three days. Gilts/sows were fed 2.72 kg/head/day until farrowing, and sows were placed on full feed 24 hours post-farrowing and allowed to eat ad libitum. Data was analyzed using the PROC MIXED of SAS as an RCBD with treatment as the fixed effect and group as a random effect. During lactation sows on the sensory additive diet showed an increase in intake during days 10 to 21 when compared to sows on the control diet (Table 1). Although it was not significantly different, sows fed sensory additive had numerically heavier weaning BW (239.4 vs 236.2 kg, P = 0.42) and increased litter weight gain (51.96 vs 48.69 kg, P = 0.24) compared to control fed sows. However, backfat thickness change during lactation did not differ between control and sensory additive fed sows (-4.74 vs -5.81 mm, P = 0.65). In conclusion, in the current study lactation diets supplemented with a sensory additive stimulated sow appetite during the lactation period.

The Impact

Abstract The impact of diet deprivation followed by overallowance during gestation on metabolic status of pregnant gilts and their lactation performance was determined. Gilts were fed a standard diet until day 27 of gestation and were subsequently reared under a control (CTL; n = 28) or an experimental (treatment, TRT; n = 26) dietary regimen. The experimental regimen provided 70% (restriction diet, RES) and 115% (overallowance diet, OVER) of the protein and NE contents provided by the CTL diet. The RES diet was given from days 28 to 74 of gestation followed by the OVER diet from day 75 until farrowing. Blood samples were obtained from all gilts on days 28, 75, and 110 of gestation, and on days 3 and 20 of lactation to measure concentrations of IGF-1, urea, FFA, and glucose. Milk samples were collected from 12 sows per treatment on day 19 of lactation and sow feed intake was recorded daily throughout lactation. Piglets were weighed at 24 h (after standardization of litter size), and on days 7, 14, and 21 (weaning). The TRT gilts gained less BW than CTL gilts (17.3 vs. 31.7 kg; P < 0.01) from days 28 to 75 of gestation and more BW (29.5 vs. 21.9 kg; P < 0.01) from days 75 to 110, but their overall gain from mating to day 110 was lower (61.4 vs. 67.2 kg; P < 0.05). Metabolic status during gestation was affected, with TRT gilts having less IGF-1 and urea, and more FFA than CTL gilts on day 75 (P < 0.01), and more urea on day 110 (P < 0.01). Growth rate of suckling piglets, sow lactation feed intake, and standard milk composition in late lactation (DM, fat, protein, lactose) were not affected by treatment (P > 0.10). In conclusion, diet deprivation of gilts as of day 28 of gestation followed by overfeeding from day 75 of gestation until farrowing did not improve lactation performance. It is likely that the compensatory growth that took place in late gestation was not adequate to illicit beneficial effects.

Arginine Supplementation

The objective of this review is to provide an overview of the implication of amino acids (AA) in important physiological functions. This is done in the context of pig production where the competition for AA utilisation is exacerbated by constraints to maximise productive responses and the necessity to reduce dietary protein input for environmental, economic and sanitary issues. Therefore, there is an opportunity to refine the nutritional recommendations by exploring the physiological roles of AA. For example, methionine and cysteine, either in selenised or sulfur forms, are directly involved in the regulation of the glutathione antioxidative system. In sows, glutathione antioxidative system may contribute to improving ovulation conditions through control of oxidative pressure. Supplementation of sow diets withl-arginine, a precursor of NO and polyamines, may stimulate placental growth, promoting conceptus survival, growth and tissue development. The beneficial effect of arginine supplementation has been also suggested to improve lactation performance. Feed intake is usually the first response that is impacted by an inadequate AA supply. Valine and tryptophan imbalances may act as signals for decreasing feed intake. AA are also important nutrients for maintaining the animal's defence systems. Threonine, one of the main constituents of mucin protein, is important for gut development during the postnatal period. It may exert a protective effect that reduces the impact of weaning on gut morphology and associated disturbances. Finally, tryptophan is involved in the regulation of the defence system through its action as a precursor of antioxidants and its effect on the inflammatory response.

Two experiments were performed with 78 second parity Lacombe sows to determine the influence of nutrition on reproductive performance. During a lactation of 35 d sows were fed daily either 3 (L) or 6 kg (H) of a diet having 16% crude protein and 12.5 MJ DE kg−1. For exp. 1, six L- and six H-fed sows were given an intravenous injection of gonadotropin releasing hormone (GnRH) at 21 d of lactation and blood was sampled at −30, −10, 0, 10, 20, 30, 45, 90 and 120 min from the time of injection. Prestimulation luteinizing hormone (LH) levels were lower for L-fed than for the H-fed sows (1.34 ± 0.1 vs. 1.93 ± 0.2 ng mL−1' P < 0.02). Peak LH levels achieved after UnKH injection, however, did not differ significantly (5.0 ± 0.6 and 5.8 ± 0.5 ng mL−1 for L and H sows, respectively). In exp. 2, 38 sows were fed the H and 40 fed the L level of feed throughout a 5-wk lactation. As expected, low-level feeding in lactation resulted in a greater body weight and backfat loss (17.4 ± 1.6 vs 41.2 ± 2.3 kg and 3.2 ± 0.4 vs. 6.3 ± 0.1 mm; P < 0.001 for both). Low-level feeding also resulted in an increased incidence of anestrus (15.0 vs. 0.0%) and an extended remating interval (140.7 ± 11.7 vs. 103.4 ± 2.1 h; P < 0.05). At the postweaning estrus, sows were inseminated with either fresh (F) or thawed (T) semen. Treatment groups were thus HF, LF and LT. Pregnancy rate was influenced by both feed level and semen type (90, 72, 69 and 39% for groups HF, HT, LF and LT, respectively). Ovulation rate was unaffected by feed intake (18.7 ± 0.9 vs. 18.2 ± 0.5 for L and H sows, respectively) but embryo survival was influenced by both feed intake and semen type (82.7 ± 2.5, 46.4 ± 9.7, 68.3 ± 9.6 and 53.7 ± 9.8% for groups HF, HT, LF and LT respectively). Eight H and twelve L-fed sows were blood-sampled via indwelling vena caval cannulae at 6-h intervals from weaning until the end of estrus. No treatment effect was noted for plasma levels of LH, growth hormone, estradiol-17β or testosterone during this period. It was concluded that low-plane feeding in lactation and the consequent increased weight and backfat loss reduce reproductive performance of sows. However, the mechanism(s) controlling this effect remain to be fully elucidated. Key words: Sow, lactation, nutrition, estrus

Abstract This study was conducted to investigate the effects of different feeding strategies during gestation on the reproductive performance of sows. A total of 1121 American Landrace-Yorkshire (YL) crossbred sows and parity from 1 to 4 were assigned randomly to “North American System” feeding pattern or “Danish System” feeding pattern during gestation basing on the backfat thickness and body weight. Sows received the same diet and fed ad libitum during lactation. Results showed that over the entire gestation period, there was also no difference in average daily feed intake and total feed intake between two groups (P &gt; 0.05). “Danish System” group has significantly improved the backfat thickness at gestation 30 d (P &lt; 0.01). At 110 d of gestation, there was no difference of the backfat thickness between two groups (P &gt; 0.05). “Danish System” group had significantly increased the total number of born (P = 0.02) and born alive (P = 0.04). The number of total born (P = 0.04), stillborn (P = 0.05) and mummies (P = 0.02), had significantly different in between parities of sows. Mummies had significantly interaction effect (P = 0.01). No different was observed for the number of weaned pigs, litter weight at weaning, piglet weight, and weaning to oestrus interval between two groups. However, a significant increase of litter weight at weaning, piglet weight, was associated with increased parity of sow (P &lt; 0.01). The results of the present investigation showed that “Danish System” group could significantly increase the litter size and number born alive. Our findings point to the importance that the Danish system can be applied to North American genotypes.

The impact of supplementing the diet of lactating sows with NuPro® (a source of yeast-derived proteins) on their performance and that of their piglets was studied. Treatments were: control (CTL, n=22), 30 g of NuPro per day (NuPro30, n=22), and 60 g of NuPro per day (NuPro60, n=21). The NuPro was mixed daily with 500 g of feed and provided over a 21-d lactation. Jugular blood samples were obtained from sows on days 2, 7 and 20 of lactation to measure urea concentrations. Milk samples were obtained on days 7 and 20 of lactation for compositional analyses and quantification of 5′ monophosphate nucleotides. Litter size was standardized to 10±1 at 48 h postpartum. Sow body weight loss and backfat loss during lactation were recorded, as well as the weights of piglets until day 56. Feed intakes of sows during lactation and of piglets for 5 wk post-weaning were noted. Statistical analyses were performed with PROC MIXED using an analysis of variance with one factor (three levels) according to a completely randomized design. None of the animal performance data differed among treatments (P>0.1). Standard milk composition was also similar across treatments (P>0.1). Concentrations of nucleotides in milk were greater on day 7 than on day 20 of lactation (P<0.001) but were not affected by treatments (P>0.1). In conclusion, supplementing the diet of lactating sows with NuPro did not increase nucleotide concentrations in milk and had no beneficial effects on sow or piglet performances.

Abstract Lysine and energy supply in gestation can influence preweaning mortality and sow lactation feed intake but little data exists for the impact on offspring post-weaning performance. A study evaluated the effects of dietary Lys:energy during gestation on offspring performance from weaning until market. Both primiparous and multiparous females (n=59 in 2 groups) were blocked by parity, balanced by weight and allotted to one of three gestation feeding regimens: 1.50 g SID Lys/Mcal ME (Control), 1.50 g SID Lys/Mcal ME from d2–89 and 2.11 g SID Lys/Mcal ME from d90–110 d of gestation (PF1) and 1.25, 1.07, and 0.88 g SID Lys/Mcal ME from d2–89 for gilts, parity 1 and parity 2+, respectively and 2.11 g SID Lys/Mcal ME from d90–110 d of gestation (PF2). Offspring (n=682) were weaned into 40 pens by maternal treatment (n=13-15 pigs/pen, mixed gender/pen). Pen feed disappearance and individual pig weights were determined at least once each month until market. Animals were marketed by a technician blinded to treatment; to account for potential marketing bias, adjusted d130 weight was calculated. Data were analyzed as a randomized complete block with means separation using Scheffe’s adjustment. The offspring of Control sows had decreased BW at weaning (P &lt; 0.001) versus PF1 offspring and Control offspring had decreased BW (P = 0.001) compared to both PF1 and PF2 at d7 post-weaning. Despite minimal differences in ADG, ADFI, or G:F between treatments, PF2 offspring were heavier (P = 0.02) at market and adjusted d130 weight than Control pigs. While PF1 offspring had similar BW at market than Controls, they spent fewer (138.2 vs. 142.7; P = 0.009) days on feed than Control pigs due to the aforementioned marketing bias. Altered Lys:energy ratio in a single gestation cycle improved offspring post-wean performance.

SummaryA trial was run to examine the influence of feeding a rumen specific live yeast, Levucell SC™ (Lallemand Animal Nutrition, Hamilton, New Zealand), on feed intakes and body weights of calves at weaning. Sixty male, Friesian cross calves, aged four days old, were randomly allocated to either a control (unsupplemented) creep feed diet or one containing Levucell SC™, a rumen specific strain of live yeast. All calves were fed a commercial milk replacer (CMR) and offered straw and creep feed ad libitum from entry, and intakes and weight gains were recorded. At six weeks of age, the calves were transferred to grazing with ad libitum access to creep feed and monitored for a further two weeks, covering the transition period from milk to grazing. The calves fed Levucell SC™ had higher feed intakes at weaning (1.105 kg/day versus 1.523 kg/day at seven weeks of age; P = 0.0434 and 1.179 kg/day versus 1.965 kg/day at eight weeks of age; P = 0.0272 for control and Levucell SC™ respectively). Correspondingly, average daily gain (ADG) was improved. At seven weeks of age, ADG was 0.659 kg versus 0.912 kg (P = 0.039), and at eight weeks of age ADG was 0.457 kg versus 0.707 kg (P = 0.0650) for control and Levucell SC™ respectively. It was concluded that supplying Levucell SC™ via creep feed prevented the drop off in calf performance at weaning, in terms of both feed intake and weight gain. This is important, as early rumen development and pre-weaning growth rates are related to a reduction in gastric upsets at weaning, future growth performance in calves and future lactation performance.

The Impact

The impact of a challenge with moderately pathogenic <em>Escherichia coli</em> O128:C6 on the digestive physiology and gut bacterial community of growing rabbits under two feeding programmes was analysed. Upon weaning (28 d old), 180 rabbits were allocated to four groups (9 cages of 5 rabbits per group) for two weeks: group C100 was non-inoculated and fed <em>ad libitum</em>; C70 was non-inoculated and feed intake was limited to 70% of C100; I100 and I70 were inoculated and fed <em>ad libitum</em> or restricted to 70%, respectively. At the age of 31 d (D0), rabbits were orally inoculated with <em>E. coli</em> (2.2×108 colony forming units/rabbit). The effects of inoculation spiked on D4, with a 28% lower growth rate for I100 than for C100. Limited feed intake reinforced the inoculation’s effects on growth: I70 had a 66% lower growth rate than C70. The morbidity rate peaked at 42% between D4 and D7 for inoculated groups, without significant effect of the feed intake level. <em>E. coli</em> concentration peaked on D5/D6 in the caecum of the I100 and I70 groups. Inoculation reduced by 30% (<em>P</em>&lt;0.05) the villus height/crypt depth and villus/crypt area ratios in the ileum, with no significant effect of the intake level. Inoculation was associated with a tenfold increase in serum haptoglobin (<em>P</em>&lt;0.001) for both <em>ad libitum</em> and restricted rabbits. On D5, the inoculation modified the structure of the ileal bacterial community (<em>P</em>&lt;0.05), but not that of the caecum. The feed intake level did not affect either the structure or diversity of the bacterial community, both in the ileum and caecum.
