“…For the first week, only the SDPP level affected the performance of the piglets, where its inclusion improved the BW at seven days of trial and the ADG 0–7 in a quadratic way, with the predicted optimum level of 4.6% and 5.1%, respectively. Similar to our results, Chae et al (), Grinstead et al () and Hernández, Hansen, Mansfield, Mullan, and Pluske () found increased ADG for pigs consuming 5% of SDPP in the diet compared to those pigs that did not receive it. However, these authors suggest that the improvement was due to the increase of the ADFI, which was not observed in this study.…”

The objective of this study was to evaluate the effects of spray‐dried porcine plasma (SDPP) on performance, measurement of thyroid hormones triiodothyronine (T3) and thyroxine (T4), body temperature and relative organ weights of weaned piglets exposed to a heat stress or a thermoneutral environment. One hundred and forty‐four piglets with initial BW of 5.82 ± 0.33 kg (28 d old) were used. The experimental design was a 4 x 2 factorial arrangement, four plasma levels (0.0, 2.5, 5.0 and 7.5%) and two environments (34º [heat stress (HS)] and 24°C [thermoneutral (TN)]). SDPP was fed from weaning (28 d of age) to the end of the trial (piglets were weighed at the beginning, 7, 21 and 35 days of trial). Rectal, neck, shoulder and leg temperatures were measured every seven days. At 21 days of trial, one piglet per pen was slaughtered to determine the weight of the carcass and organs. Blood samples were collected at 18 and 35 days of trial to determine levels T3 and T4. The rectal, neck, shoulder and leg temperatures were increased (p < 0.05) 0.4, 1.5, 1.0 and 1.3ºC, respectively, and relative weight of the lungs (p < 0.05) and total T3 (p < 0.05) were decreased 0.001 kg/kg and 0.19 ng/dl, respectively, for pigs in the HS environment. The estimated inclusion of 5.1% of SDPP had the greatest (p < 0.05) weight gain during the first week, and throughout the nursery phase, the 5% of inclusion had a tendency of improvement (p = 0.075), regardless of ambient temperature. For the entire period, pigs reared in the HS environment had the greatest (p < 0.05) estimated feed intake by the quadratic regression with the inclusion of 4.3% of SDPP.

“…Surprisingly, NORM ‘high’ pigs had significantly lower IgG concentration than NORM ‘low’ at 28 d post-weaning, and did not differ from WEAN pigs at any sampling point. In contrast, a different study [ 21 ] found lower IgG concentration in low (≈ 5 kg) wean weight pigs compared to normal (≈ 7 kg) wean weight pigs. Our findings might suggest that, at the same age, small pigs might benefit from a higher quality diet post-weaning, whereas in normal weight pigs a ‘high’ starter diet allowance does not enhance their immunological maturity compared to a ‘low’ allowance.…”

Objective: To evaluate the use of nurse sows and post-weaning nutrition strategies for low wean weight (WW) pigs on lifetime growth and efficiency.Methods: Animals (n = 270) were assigned to one of five treatments at 28 d. Low WW pigs (<6 kg) were either weaned and offered a special dietary regime recommended for low WW pigs (WEAN) or placed on a nurse sow (NURSE) and weaned at 49 d. Normal WW pigs (9 kg) (NORM) were also weaned at 28 d. After weaning, NORM and NURSE pigs were offered either a ‘high’ (4 kg/pig of starter 1 diet followed by 8 kg/pig of starter 2 diet) or ‘low’ (8 kg/pig of starter 2 diet) starter diet allowance in a 2×2 factorial arrangement. A typical grower diet was then offered, followed by a typical finisher diet until 147 d of age.Results: NORM pigs where heavier throughout their life compared to NURSE pigs (91.4 kg vs 76.2 kg at 147 d; p<0.001). WEAN pigs were heavier at 70 d compared to NURSE pigs (23.9 kg vs 21.0 kg; p<0.001), but there was no significant difference at 147 d between NURSE and WEAN treatments. NURSE pigs had reduced feed intake throughout the finishing period (1.6 kg/d; p<0.001) compared to WEAN (2.0 kg/d) and NORM (1.9 kg/d) pigs. Feed conversion ratio (FCR) of NURSE (2.20) was lower than NORM and WEAN during the finishing period (2.40 and 2.79, respectively).Conclusion: Extended (up to 49 d) nursing for low WW pigs resulted in improved FCR during the finishing period, but no overall improvement in growth rate compared to low WW pigs weaned at 28 d and offered a specialised starter regime. Normal WW pigs where significantly heavier than low WW pigs throughout the study.

“…However, few studies have focused on this functional feedstuff in other animals, such as fish (Gisbert et al, 2015) and cats (Rodriguez et al, 2016). Although the mechanisms by which SDP improves growth performance have not been totally elucidated (Touchette et al, 2002;Tran et al, 2014), the majority of studies have observed that enhanced growth performance (Ermer et al, 1994;Bosi et al, 2004;Diehl, 2004;Pierce et al, 2005;Hernández et al, 2010;Gisbert et al, 2015) and intestinal protection (Bosi et al, 2004;Campbell et al, 2010;Tran et al, 2014;Gisbert et al, 2015) are associated with higher feed intake. In our study, these benefits were observed for the growth performance parameters, such as the FBW, SGR, RWG and FI, as well as for the intestinal functions as demonstrated by decreases in the crypt depth and increases in the villus:crypt ratio.…”

Nutritional strategies can help fish manage stress, and functional feedstuffs are an interesting nutritional option. Therefore, this study evaluated the potential functional effect of spray-dried plasma (SDP) on Nile tilapia growth performance and the capacity of SDP to improve fish health under cold-induced stress (CIS). A total of 440 fish (12.64 ± 0.64 g) were randomly distributed into 40,250-L aquaria and fed five diets containing graded levels of SDP (0, 16.6, 33.2, 49.7 and 66.3 g kg − 1) for 60 days. The growth performance, villus height:crypt depth ratio, and hematological parameters were analyzed, and the same hematological parameters were then analyzed after 7 days of CIS. Based on the broken-line analysis of the FBW, SGR, RWG and FCR, the optimum dietary level supplementation of SDP was determined to be 49.70, 50.16, 51.83 and 41.83 g kg − 1 diet, respectively. The crypt depth and villus:crypt ratio were positively affected by SDP supplementation. After CIS, hematocrit of fish fed 16.6 g kg − 1 of dietary SDP was significantly lower than fish fed 66.3 g kg − 1 level (P < 0.05). The supplementation level of dietary SDP and the CIS affected the leukocyte, lymphocyte and neutrophil counts. The monocyte count was affected by the dietary SDP supplementation level both before and after CIS (P < 0.05). Total plasma protein concentration in the fish fed 49.7 and 66.3 g kg − 1 SDP were significantly higher than fed 16.6 g kg − 1 SDP after CIS (P < 0.05), and CIS led to a higher Albumin:Globulin ratio (P < 0.05). Dietary SDP supplementation improved the growth performance, intestinal health, hematological profile and CIS resistance of the studied fish. Based on our results, we recommend a dietary supplementation level of 51.83 g kg − 1 SDP for Nile tilapia.
