“…Behavioral activity patterns, social interactions, and abnormal behaviors were recorded on a farm using instantaneous scan sampling. This was done to observe the effect of dietary treatment [17][18][19]. Two trained observers did direct observations on four pens from the middle corridor (a total of eight pens) once a week.…”

Peas are an alternative to soybeans to supply protein in livestock feeds. Immunocastration avoids surgical castration of male pigs and increases fat deposition in female pigs. This work aimed to assess the effects of pea inclusion on the amount of fat and fatty acid profile of loins and on weight losses of dry-cured hams in different sexes of pigs; in addition, growth performance and feeding behavior in immunocastrated female pigs were evaluated. Two experiments were conducted with crossbred immunocastrated female (IF) and immunocastrated (IM) or surgically castrated (CM) male pigs from Duroc dams sired by Berkshire, which were assigned to one of two diets (soybean vs. pea-based). The effect of castration type on the afore-mentioned variables was evaluated in male pigs, and the growth performance, and feeding behavior in female pigs. The pea-based diet in IF had no effect on average daily gain nor on carcass traits; although, it increased feeding time (p < 0.001) and reduced n-3 polyunsaturated fatty acid (PUFA) content (p < 0.05). In male pigs, the pea-based diet did not change carcass fatness either but reduced the n-3 PUFA levels (p < 0.05). Likewise, IM had lower (p < 0.001) monounsaturated fatty acid (MUFA) and higher (p < 0.05) n-6 PUFA than CM. Diet did not affect dry-cured ham weight losses during the process, while IM showed greater (p < 0.001) losses than CM. Pigs fed a pea-based diet complied with the requirements of cured ham production, while immunocastration in male pigs increased weight losses, partly explained by lower fat content and higher fatty acid unsaturation.

“…The inclusion of both straw and oat silage (dietary fibres) may affect the skatole production across the digestive tract since diets with high content of fermentable carbohydrates have been shown to reduce the level of cholesterol in serum (Hansen et al, 2008) and the production of skatole in backfat (Jensen and Hansen, 2006). Whereas in this experiment it was proved that the oat silage supplement reduced the cholesterol content in adipose tissue (Argemí-Armengol et al, 2020), the levels of skatole were not reduced in fat tissue. In this work, the degradation of non-starch polysaccharides (NSP) of roughages in the large intestine of pigs was not determined, but it depends on the degree of lignification, solubility and structure of the polysaccharides (Bach Knudsen, 2001).…”

In organic pig husbandry, the use of roughage is mandatory as dietary supplement. This study investigated the effects of oat silage on the fatty acid composition, in entire males and gilts, as well as indole and skatole levels in perirenal adipose tissue of entire males. Entire males and gilts (forty-five to forty-eight pigs/sex) were assigned to two dietary roughage feeds (control with straw vs. oat silage). There was no significant effect of silage or sex on total SFA and MUFA in pork fat. However, the oat silage increased the total PUFA n-3 and decreased the PUFA n-6/n-3 ratio. The content of boar taint compounds (skatole and indole) in the entire male pigs did not differ between diets, although human nose scoring rejected in a greater extent more pork fat from entire males supplemented with oat silage, compared with those only supplied with straw. Approximately 50% of the entire males (90 to 97 kg of carcass) had low skatole values (≤0.1 μg/g), that were below the range of boar taint detection, regardless of the feeding regime. This finding indicates that more studies should be performed to avoid the problem of taint detection in entire males under organic production.

Background This study aimed at investigating the effects of mycotoxin challenge on the growth and physiology of nursery pigs with different weaning weights. Results At weaning, 10 pigs were euthanized to collect jejunal mucosa and 90 pigs were assigned following a randomized complete block design in a 2 × 2 factorial arrangement of treatments with 3 pigs per pen. Factors were: weaning weight (light: body weight, BW < 7.5 kg or heavy: BW > 9.0 kg); and dietary mycotoxins (supplementation of 0.2 mg/kg aflatoxins, 2.0 mg/kg deoxynivalenol). All diets had titanium dioxide as an external marker at 0.5%. Growth performance and fecal score were recorded until pigs achieved 20 kg BW (light pigs average BW = 21.1 kg and heavy pigs average BW = 20.5 kg). Pigs were sampled for blood, ileal digesta, jejunal tissue and mucosa at 20 kg BW. Data were analyzed using the mixed procedure of SAS. At weaning, light pigs had decreased (P < 0.05) jejunal interleukin-8, increased (P < 0.05) tumor necrosis factor-α, and increased (P < 0.05) α-diversity indexes of jejunal mucosa-associated microbiota. At 20 kg of BW, light pigs had decreased (P < 0.05) average daily gain (ADG), average daily feed intake (ADFI), and gain to feed ratio (G/F). Mycotoxins decreased (P < 0.05) BW, ADG, ADFI, and G/F. Light pigs tended to have increased fecal score on d 0 (P = 0.080), d 10 (P = 0.069), and increased (P < 0.05) fecal score at 20 kg. Mycotoxins decreased the apparent ileal digestibility of nitrogen (P < 0.05). Light pigs had increased (P < 0.05) intestinal malondialdehydes and interleukin 8. Mycotoxins tended to increase (P = 0.060) intestinal tumor necrosis factor-α. Conclusions Nursery pigs with light weaning weight were more susceptible to jejunal inflammation and had impaired intestinal health due to weaning stress, whereas mycotoxins diminished the health and growth of nursery pigs regardless of weaning weight.
