The objective of the present study was to<br>determine the effect of dietary gel protein supplementation on pre-weaning mortality and growth in piglets. A total of<br>48 Landrace x Yorkshire crossbred sows were included in this study. On farrowing day, the sows were randomly<br>allocated into two experimental groups by parity: Control (n=20) and Treatment (n=28)</span><span class="fontstyle2">. </span><span class="fontstyle0">The piglets in the Control<br>group sows (n=234) were not orally supplemented and the piglets in the Treatment group sows (n=316) were orally<br>supplemented with gel protein (Porcistart</span><span class="fontstyle0">®</span><span class="fontstyle0">, Virbac. Co., Ltd., Loudeac, France). The piglets in the treatment group had<br>ad libitum access to gel protein in a container placed in the creep area for the piglets. The feeding protocols were carried<br>out from farrowing day until Day 7 after farrowing. The creep feed was provided from day 7 until weaning. On Day 7<br>after farrowing, 2 mL blood samples were obtained from 160 piglets (Control, n = 54 and Treatment, n = 106) randomly<br>selected from sows included in the experiment for IGF-1 analysis. The piglet body weight was recorded at Days 3, 10<br>and weaning. The litter weight gains were calculated. The piglet pre-weaning mortality was determined at Days 3, 10<br>of life and at weaning. The lactation length, litter size at Days 3 and 10 and weaning were 25.5 ± 0.9 days, 11.5 ± 1.8<br>piglets/litter, 10.0 ±1.5 piglets/litter and 9.6 ± 2.1 piglets/litter, respectively. No effect of gel protein supplementation<br>on piglet weaned weight and piglet pre-weaning mortality was found in the present study (</span><span class="fontstyle3">P </span><span class="fontstyle0">> 0.05). On average, the<br>serum IGF-1 concentration was 128.1 ± 54.7 ng/ml (range 22.6-243.5 ng/ml) and piglet weaned weight was 6.7 ± 1.3<br>kilograms (range 4.4-8.9 kilograms). Serum IGF-1 concentration in the treatment group (140.3 ng/ml) was higher than<br>in the control group sows (120.2 ng/ml, </span><span class="fontstyle3">P </span><span class="fontstyle0">= 0.027). In conclusion, dietary gel protein supplementation in the piglets<br>increased piglet serum IGF-1 but had no effect on weight and pre-weaning mortality in piglets.</span> </p>}, number={4}, journal={The Thai Journal of Veterinary Medicine}, author={Nuntapaitoon, Morakot and Suwimonteerabutr, Junpen and Am-in, Nutthee}, year={2020}, month={Dec.}, pages={567–572} }
