“…Additionally, the effect of BW at slaughter was significantly associated with OC prevalence, while treatment effects became non-significant. In contrast to studies that could not find associations of BW with OC (Woodard et al, 1987;Jørgensen, 1995;Ytrehus et al, 2004b), the results of BW association with OC in the current study agrees with other studies (Carlson et al, 1988;van Grevenhof et al, 2011;de Koning et al, 2013;Quinn et al, 2015). These studies indicate that animals fed (up to 20%) below ad libitum feed level show a reduction in OC prevalence.…”

“…Lameness can be caused by injury due to poor housing conditions, non-infectious and infectious conditions, and degenerative diseases (34–36). Individuals can also be genetically predisposed to lameness (37), and lameness can be associated with inadequate nutrition, relating to growth rate (38). Additionally, a chemically induced transient lameness model was developed in sows to study clinical lameness detection and analgesic strategies (39).…”

A Review of Pain Assessment in Pigs

There is a moral obligation to minimize pain in pigs used for human benefit. In livestock production, pigs experience pain caused by management procedures, e.g., castration and tail docking, injuries from fighting or poor housing conditions, “management diseases” like mastitis or streptococcal meningitis, and at parturition. Pigs used in biomedical research undergo procedures that are regarded as painful in humans, but do not receive similar levels of analgesia, and pet pigs also experience potentially painful conditions. In all contexts, accurate pain assessment is a prerequisite in (a) the estimation of the welfare consequences of noxious interventions and (b) the development of more effective pain mitigation strategies. This narrative review identifies the sources of pain in pigs, discusses the various assessment measures currently available, and proposes directions for future investigation.

“…The sulfur donator capacity of Met might enhance osteoblast differentiation (Ouattara et al, 2016) and increase collagen and bone formation by increasing osteocalcin. Similarly, Quinn et al (2015) found that additional trace minerals (TM) combined with feed restriction improved locomotor ability and reduced joint lesions. Additional Cu, Mn, and Zn have also shown improvements in claw health with lower horn tubules diameter, higher horn density, and reduced laminitic changes (Lisgara et al, 2016;Varagka et al, 2016).…”

“…Osteochondrosis (OC), arthritis, and claw disorders are the most frequent causes of lameness which affect the bone, articular cartilage, and hoofs (Yazdi et al, 2000;Bradley, 2010). Moreover, several interrelated factors such as genotype, diet composition, growth rate, and mechanical stress are thought to be important in lameness (Nakano and Aherne, 1988;Busch and Wachmann, 2011;de Koning et al, 2014;Quinn et al, 2015;Le et al, 2016). Copper (Cu), manganese (Mn), and zinc (Zn) are involved in cartilage and horn development (Orth, 1999;Tomlinson et al, 2004;Riet et al, 2013).…”

Lameness is a primary reason for culling and mortality within a sow herd. This study evaluated the impact of feeding organic trace minerals and methionine (Met) to growing gilts (134 d) on lameness, performance, body composition and claw health (to first parity), productivity (to second parity), and reproductive performance through 2 parities. Young gilts (28.8 ± 8.8 kg of body weight [BW], n = 360) were BW blocked (10 gilts/pen) and randomly allotted to 1 of 4 dietary treatments: control (CON, basal diet); CON plus organic minerals (MIN, at 10, 20, and 50 mg/kg of Cu, Mn, and Zn, respectively; Aplomotec Plus, Tecnología & Vitaminas, S.L, Alforja, Spain); additional Met (MET, at 102% Met: Lys); and MET plus MIN (MM). Feed was provided ad libitum. Lameness, BW, and body composition were measured 7 times during rearing, at gilt service, day 109 of gestation, and first weaning. Gilts fed the MM diet had lower average daily feed intake (5.1%) and final BW (2.1%) than CON gilts (P < 0.05), whereas MIN and MET were intermediate and not different from each other. Similarly, final backfat (BF) was greatest in CON (P < 0.05), whereas CON and MIN increased final loin depth compared with MM (P < 0.05) with MET not being different. During rearing, 7.7% of all gilts presented lameness, which appeared between 106.8 and 129.7 kg BW confidence interval. Gilts that had been or were lame had reduced BW and average daily gain compared with never lame gilts (P < 0.05). Lameness during rearing was highest (P < 0.01) in gilts fed CON diet (14.8%), with no differences amongst MIN (2.0%), MET (5.3%), or MM (6.5%). In the sow herd, 21% of sows showed lameness and 24% of those were associated with claw lesions. At weaning, gilts fed CON diet had highest (P < 0.01) prevalence of lameness (20.8%) with no differences amongst MIN (6.5%), MET (11.1%), or MM (7.6%). Over the first 2 parities, 27.3% of gilts were culled. On farm, lameness was associated with 0.7 more stillborn piglets (P < 0.10), 1 mm more BF loss in first lactation (P < 0.05), and increased weaning-to-estrus by 3 d (P < 0.05). In conclusion, lameness during rearing was decreased by supplementing organic trace minerals, methionine, and their combination, which also reduced lameness during lactation.
