Abstract A total of 45 Landrace × Yorkshire multiparous sows were used to evaluate the effect of dietary herbal extract mixture (Scutellaria baicalensis and Lonicera japonica, HEM) supplementation in lactating sows under heat stress. Sows were randomly allotted to 1 of 3 dietary treatments: 1) CON, basal diet; 2) TRT 1, basal diet with 5 g/d HEM; 3) TRT 2, basal diet with 10 g/d HEM. During lactation, dietary HEM supplementation linearly increased (P<0.05) the average daily feed intake (ADFI) and linearly decreased (P<0.05) backfat loss. The digestibility of dry matter (DM) was increased after farrowing (linear, P<0.05; quadratic, P<0.05) and weaning (linear, P<0.05) by HEM supplementation. Furthermore, HEM treatment led to a lower (linear, P<0.01) serum cortisol level. In addition, administration of HEM improved (linear, P<0.05) the piglets weaning weight and overall average daily gain (ADG) during suckling period. Meanwhile, on day 7 and 14 after birth, the fecal score of piglets was decreased (linear, P<0.01) by HEM supplementation. Taken together, under high ambient temperatures, inclusion of HEM to lactation diets could improve the feed intake, digestibility of DM, piglets weaning weight and ADG, while decreasing backfat loss, serum cortisol level, as well as the diarrhea of piglets.

Road Transportation

Magnesium (Mg) supplementation has shown to modulate the stress responses to transport in other species. An experiment was designed to evaluate the effect of Mg for alleviating stress associated with road transportation in lambs. Two groups (n = 18 each) of 4-month old male crossbred lambs (24 ± 4.5 kg) were fed a basal diet comprising oaten hay, pellets and barley, that contained 0.17% Mg. One group was supplemented with magnesium oxide, such that dietary Mg was 0.41%. At the end of the 2-week supplementation period, the lambs were transported by road for 8 h. Blood samples were collected before supplementation, 1 h before transport, within 0.5 h post-transport, at 2 h post-transport and 5 days post-transport. Data were analysed using a repeated-measure analysis of variance and linear mixed model with treatment within time interaction. Supplementation with dietary Mg in the form of MgO increased serum Mg concentrations (1.16 mmol/L ± 0.012, compared with 1.09 mmol/L ± 0.013 in the control group; P < 0.05), but had no effect on alleviating stress during transportation. Transport resulted in a significant increase in serum cortisol, which returned to pre-transport levels 2 h after transport. The serum β-hydroxybutyrate was significantly higher 5 days after transport. The post-transport average feed intake and the average daily gain were significantly lower than pre-transport values, suggesting that the stress of transportation resulted in a decrease in feed intake post-transport, which could have implications on liveweight gain of animals after transportation.

Abstract A total of 109 sows (Line 241; DNA, Columbus, NE) were used in a study to evaluate the effect of increasing phytase concentration in lactation diets on sow and litter performance. On d 107 of gestation, sows were blocked by body weight and parity and allotted to 1 of 3 dietary treatments of increasing phytase concentration (0, 1,000, or 3,000 FYT/kg; Ronozyme HiPhos 2700; DSM Nutritional Products, Inc., Parsippany, NJ). The control diet contained no phytase and was formulated to contain 0.50% standardized total tract digestible phosphorus (STTD P; 0.45% available P) and 0.62% STTD calcium (0.90% total Ca). The same STTD P and Ca concentrations were formulated for the phytase diets considering a release of 0.132 STTD P and 0.094 STTD Ca in both diets. Diets were fed from d 107 of gestation until weaning (d 18 ± 2). Litters were cross-fostered within treatment until 48 h post-farrowing to equalize litter size. Linear and quadratic response to phytase concentration was evaluated using the lmer function in R. There was no evidence for difference in sow body weight change, farrowing performance, wean-to-estrus interval, or litter size among dietary treatments. Sow average daily feed intake from farrowing to weaning tended to increase (linear, P=0.093) as phytase increased. Although not significant (linear, P =0.226), farrowing duration decreased as phytase increased. Litter weaning weight increased (quadratic, P=0.039) and overall litter gain increased (quadratic, P=0.047) with 1,000 FYT of phytase. In summary, sow feed intake tended to increase linearly with increasing phytase; however, feeding 1,000 FYT/kg maximized overall litter gain and weaning weight. This small-scale study suggests sow and litter performance benefits due to high inclusions of dietary phytase; however, a commercial trial with more sows is warranted to confirm these results.

Observation Period

An investigation was undertaken on 180 day-old Hy-line layer chicks to assess the effect of herbal products on feed consumption, egg production and profitability. The experimental chicks were randomly divided in three groups with three replicates in each and were housed in identical management and environmental conditions. Dietary treatments were prepared by addition of herbal liver stimulants such as Livoliv 250 @500 g/ton (D2) and Superliv @500g/ton (D3) in the basal diet (D1). Feed intake, egg production and mortality were recorded throughout the observation period of 50 weeks. Feed per unit of egg production, hen day percentage, additional income of supplemented diet over the basal diet were calculated. Average daily intake (g) of the diets per bird were observed as 59.19±1.05 g, 58.31±0.337 g and 57.67±0.163 g up to 20 weeks and 108.94±0.06 g, 109.01±0.05 g and 108.26±0.41 g during the laying period fed with D3, D1 and D2 diets respectively. Similarly, higher hen day egg % (76.9%) was recorded in the birds fed with Superliv supplemented diet (D3), followed by Livoliv supplemented diet (D2) (73.4%) and Basal diet (D1) (72.1%) with feed intake per unit egg production of 179.3 g, 178.1 g and 193.0 g, respectively. Total egg production was found higher with D3 (161.49 egg), followed by D2 (154.15 egg) and basal diet (151.45 egg) with layer house cumulative mortality only in D3 (3.75%). Additional profits of Rs. 35.18 and Rs. 12.86 in terms of egg selling over feed cost per layer were calculated for the bird fed with Superliv supplemented diet (D3) and Liveloliv supplemented diet (D2) than that of the basal diet.

Abstract Reducing dietary crude protein (CP) with synthetic amino acids (AA) supplementation is beneficial for sustainable swine industry. However some discrepancies regarding the consequences on growth performance are observed. Therefore, this trial aimed to assess the effect of dietary CP level on growth performance of pigs from 35 to 113 kg BW. Growth performance of 63 pigs fed ad libitum and allocated to three groups (HH, MM and LL) was compared. Each group received one level of CP (‘H’ for High, ‘M’ for Medium and ‘L’ for Low) during growing (d0–d35) and finishing (d35–slaugther day) periods: 15.1%, 16.2%, 17.2% and 13.0%, 14.0%, 15.1% respectively. Diets were mostly based on wheat, corn and soybean meal. Within each feeding phase, diets were formulated to be similar in apparent total tract digestible phosphorus, net energy and standardized ileal digestible (SID) essential AA, the SID Lys levels being 0.95% and 0.78% during the growing and finishing period respectively. Data were analyzed using a linear model (R, 3.1.2) with individual as the experimental unit as feed intake, body weight and carcass grading were individually recorded. From d0 to d14 and from d35 to d63, average daily gain (ADG) and Growth:Feed ratio (G:F) were significantly reduced as the CP level decreased (P < 0.05) while average daily feed intake (ADFI) remained unaffected by the dietary treatments. From d14 to d35 and in late finishing period (d63-slaugther day), growth performance was not significantly affected by the dietary CP level. Over the 82-d of the experiment, G:F was significantly higher for ‘HH’ pigs (P < 0.01). Overall, ADG tended to be reduced as CP levels decreased (P = 0.10). There was no difference among treatments for parameters concerning carcass grading (lean meat percentage and meat yield). In conclusion, reducing CP levels while maintaining essential AA levels impaired growth performances of pigs.

Blood Profiles

A total of 45 sows (Landrace × Yorkshire) and their litters were used in this study to evaluate the efficacy of nucleotide supplementation on reproductive performance, growth performance, fecal microflora, and blood profiles in sows and piglets. Sows were allocated to one of three treatments (15 pigs per treatment and the average parity was 4.13). Dietary treatments consisted of (1) CON: basal diet, (2) T1: CON + 0.5% nucleotides, and (3) T2: CON + 1.0% nucleotides. In this study, the average daily feed intake during lactation and back fat at weaning day was increased linearly (P < 0.05) in sows with the increase in nucleotide supplementation levels. Sows receiving increasing levels of nucleotides had linearly increased fecal Lactobacillus counts and decreased Escherichia coli counts at weaning day (P < 0.05). Linear reduction of the epinephrine, norepinephrine, and cortisol in sows was observed at weaning day, whereas superoxide dismutase was increased linearly (P < 0.05). Body weight and average daily gain in piglets were linearly (P < 0.05) increased with the increasing levels of nucleotides. Linear increase (P < 0.05) was also observed on total piglets born, live piglets, and piglet survival. The current study demonstrated the importance of nucleotides in the diets of sows to improve sow and piglet performance.

Abstract Serial estimations of serum cortisol were performed in 49 patients with craniocerebral trauma. Abnormalities of serum cortisol, including alterations in diurnal rhythm and elevations of serum cortisol level, occurred in 21 patients. The frequency and severity of the abnormalities correlated with the severity of the head injury, and there was a trend suggesting that middle fossa basal skull fractures predisposed to cortisol abnormalities. A further 6 patients were studied to assess the effects of exogenous dexamethasone, and in all patients there was suppression of elevated serum cortisol levels by the dexamethasone. The findings suggest that hypercortisolemia after head injury is related to an alteration rather than an abolition of the normal feedback mechanism.

The study was designed to observe the effects of surgical stress on serum level of cortisol in patients undergoing surgical treatment and to find out any differences in hormonal response between elective and emergency surgical procedures. A total number of 60 male subjects aged between 18 and 45 years were included in the study. Of them, 20 were healthy control (Group I), 20 underwent elective surgical treatment (Group II) and emergency surgical interventions were applied in rest 20 subjects (Group III). Study Groups were further divided into subgroups A (preoperative samples were collected 1- hour before operation), B (postoperative samples were collected 1-hour after the end of the operation) and C (postoperative samples were collected 24-hours after operation).Serum cortisol level was estimated by invitro-immunolytic test.Statistical analysis was done by paired, unpaired ‘t' test and regression analysis. The preoperative mean serum cortisol concentration in elective surgical cases was almost similar to that of healthy control. On the contrary, in the emergency surgical cases, a significantly increased mean cortisol level were observed (I vs IIIA and IIA vs IIIA; P < 0.05). The serum cortisol concentrations were increased both in elective and emergency surgical cases after operations but the magnitude of rise was more marked in emergency group of patients (IIB vs IIIB; P < 0.05). Therefore, this study reveals that surgical intervention causes increase in serum cortisol which is more marked in emergency procedure.
