Abstract
Porcine digestible peptides (PDP) are high-quality hydrolysed proteins obtained from porcine intestinal mucosa as a by-product of the heparin manufacturing process. PDP contain bioactive peptides and are used as alternative protein sources in several animal species, including pigs. We aimed to explore the (carry-over) effects of feeding PDP to weaned piglets on performance and systemic cytokine levels of pigs followed until slaughter. A total of 192 piglets were allocated to one of two dietary treatments: control (CON) or PDP weaner diets. PDP was included at 5.0% until day 13 post-weaning at the expense of skimmed milk powder and partial replacement of soybean meal, and at 2.5% between days 13 and 34 post-weaning at the expense of soy protein concentrate. Grower-finishers were fed commercial diets according to a 3-phase feeding scheme until slaughter, when carcass traits were determined. Six pigs were housed per weaner pen and eight per grower-finisher pen with 16 and 10 pens per treatment, respectively. Pigs were weighed at the start and at the end of each phase, and feed intake was recorded. Faecal consistency was recorded twice a week in the weaner facility. Ten pigs per treatment were sampled for blood at days 13, 34 and 69 post-weaning. We found that PDP-fed piglets had a higher feed intake in the first two weeks post-weaning compared to CON-fed piglets (+32 g/pig per day; P = 0.02). Moreover, piglets in the PDP group showed improved feed conversion between days 13 and 34 versus the CON group (1.36 vs 1.43; P = 0.03). Piglets that were fed with PDP in the weaner diets tended to grow faster in the grower-finisher period (+32 g/pig per day; P = 0.07), tended to reach slaughter age earlier (129.9 vs 131.5 days; P = 0.07) and had a lower dressing percentage at slaughter (76.3 vs 76.7%, P = 0.045) than piglets previously fed with CON. Additionally, PDP-fed piglets showed higher serum levels of pro-inflammatory cytokines interleukin (IL)-12 (P = 0.02), tumour necrosis factor-alpha (P = 0.02), interferon-gamma (P = 0.03) and IL-8 (at day 34 post-weaning, P = 0.06) as well as anti-inflammatory cytokines transforming growth factor-beta (P = 0.02), IL-4 (P = 0.04) and IL-10 (at day 34 post-weaning, P = 0.02). No significant differences among dietary treatments were observed regarding faecal consistency of weaned piglets and carcass weight, lean meat percentage, muscle depth, and back fat thickness at slaughter. We conclude that feeding PDP, as an alternative to conventional milk and soy protein sources, showed positive effects on pig performance, not only during the provisioning period but also thereafter into the grower-finisher phase.

Abstract
The fishmeal replacement by vegetable meals or other alternative sources, without affecting fish performance and productivity, is one of the principal challenges in aquaculture. The use of hydrolyzed porcine mucosa (HPM) and nucleotide (NT) concentrates, as feed additives in gilthead seabream (Sparus aurata L.) non-fishmeal diets was assessed in order to determine the possible effects on growth, feed efficiency, protein digestion, and gut histology when these were included in a plant-based diet (HPM 1% and 2%, P1 and P2; NT 250 and 500 ppm, N250 and N500), in comparison with two control diets, AA0 (100% plant-protein-based diet) and FM100 (100% fishmeal-protein-based diet). Diets were assayed in triplicate and the growth assay lasted 134 days. Results showed a significant improvement in all groups in terms of final weight and specific growth rate in comparison with the AA0 group. An improvement in the feed conversion ratio and the protein efficiency ratio was also observed when the additives were included in lower percentages (P1 and N250) compared to the FM100 group. Significant differences were found in hepatosomatic index, villi thickness, and goblet cells. Thus, the inclusion of NT and HPM was tested as beneficial for the improvement of efficiency of plant feed in seabream.

Abstract
Iso-nitrogenous and iso-lipidic diets containing 0%, 3%, 6%, 9%, and 12% hydrolyzed porcine mucosa (namely, HPM0, HPM3, HPM6, HPM9, and HPM12) were prepared to evaluate their effects on the growth performance, muscle nutrition composition, texture property, and gene expression related to muscle growth of hybrid groupers (Epinephelus fuscoguttatus ♀ × Epinephelus lanceolatus ♂). Groupers were fed to apparent satiation at 08:00 and 16:00 every day for a total of 56 days. It was found that the weight gain percentage in the HPM0, HPM3, and HPM6 groups did not differ (P > 0.05). The cooking loss and drip loss of the dorsal muscle in the HPM3 group were lower than those in the HPM6 and HPM9 groups (P < 0.05). The hardness and chewiness of the dorsal muscle in the HPM3 group were higher than those in the HPM0, HPM9, and HPM12 groups (P < 0.05). The gumminess in the HPM3 group was higher than that in the HPM9 and HPM12 groups (P < 0.05). The total essential amino acid content of the dorsal muscle in the HPM12 group was higher than that in the HPM0 group (P < 0.05). The contents of total n-3 polyunsaturated fatty acid and total n-3 highly unsaturated fatty acid, as well as the ratio of n-3/n-6 polyunsaturated fatty acid in the dorsal muscle was higher in the HPM0 group than in all other groups (P < 0.05). The relative expressions of gene myogenic factor 5, myocyte enhancer factor 2c, myocyte enhancer factor 2a, myosin heavy chain, transforming growth factor-beta 1 (TGF-β1), and follistatin (FST) were the highest in the dorsal muscle of the HPM3 group. The results indicated that the growth performance of hybrid grouper fed a diet with 6% HPM and 27% fish meal was as good as that of the HPM0 group. When fish ingested a diet containing 3% HPM, the expression of genes TGF-β1 and FST involved in muscle growth were upregulated, and then the muscle quality related to hardness and chewiness were improved. An appropriate amount of HPM could be better used in grouper feed.

Abstract
Three double-choice feeding experiments were conducted to study the effect of different feedstuffs on feed preference in pigs. Fifteen protein sources, 6 fat sources, and 3 fiber sources were evaluated in Exp. 1, 2, and 3, respectively. Pigs were offered a series of double choices between a common reference diet and the diet with the ingredient under evaluation. The reference diet contained a soybean meal product with 56% CP (SBM-56), sunflower oil, and wheat bran, which were considered as the feedstuffs of reference for the protein, fat, and fiber sources, respectively. Preference, expressed as percentage of the tested diet to total feed intake, was affected by feedstuff nature and by its inclusion rate. In Exp. 1, feeds with fish meal at 50 and 100 g·kg⁻¹, dried porcine hydrolyzed protein at 50 g·kg⁻¹, and lupine, soybean meal with 44% CP, and dried skim milk at 100 g·kg⁻¹ were preferred (P < 0.05) to the reference feed with SBM-56. On the contrary, relative to SBM-56, an avoidance (preference less than 50%) was observed for potato protein at all inclusion rates tested, rapeseed meal and acid milk whey at 100 and 200 g·kg⁻¹, and dried porcine hydrolyzed protein, soybean protein concentrate, wheat gluten, and sunflower meal at 200 g·kg(-1). The storage of dried skim milk, soybean protein concentrate, and potato protein for 10 mo resulted in a reduction (P < 0.001) of their preference values. In Exp. 2, the feed with palm oil (at 30 g·kg⁻¹) was preferred (P < 0.05), whereas feeds with linseed oil (at 30 and 100 g·kg⁻¹) and soybean oil (at 100 g·kg⁻¹) were avoided (P < 0.05) when contrasted with the reference feed with sunflower oil. Finally, in Exp. 3 diets with dehydrated alfalfa and sugar beet pulp at 130 g·kg⁻¹ had a reduced (P < 0.05) preference compared with the reference diet with wheat bran. It is concluded that feedstuff nature, inclusion rate, and freshness affect feed preference in pigs. Feedstuff preferences should be taken into account during diet formulation, particularly at critical stages such as immediately after weaning.
