Uso de microminerais complexados na redução de lesões de casco em reprodutoras suínas/  Use of complexed trace minerals to improve claw lesions in swine sows

Plant-based foods are rich sources of vitamins and essential micronutrients. For the proper functioning of the human body and their crucial role, trace minerals (iron, zinc, magnesium, manganese, etc.) are required in appropriate amounts. Cereals and pulses are the chief sources of these trace minerals. Despite these minerals, adequate consumption of plant foods cannot fulfill the human body’s total nutrient requirement. Plant foods also contain ample amounts of anti-nutritional factors such as phytate, tannins, phenols, oxalates, etc. These factors can compromise the bioavailability of several essential micronutrients in plant foods. However, literature reports show that fermentation and related processing methods can improve nutrient and mineral bioavailability of plant foods. In this review, studies related to fermentation methods that can be used to improve micronutrient bioavailability in plant foods are discussed.

Claw Lesions

Lameness is often diagnosed in cattle with left displacement of the abomasum (LDA). Laterality of lying has an effect on the etiology of LDA, and lame cows prefer to lie on the affected limb. The objective of this study was to investigate the possible association between laterality of claw lesion and presence of LDA. The medical records of 252 cattle presented with a diagnosis of LDA and subjected to a diagnostic examination of claw lesions over a period of 11 years (2009–2019), were analyzed retrospectively. Data were evaluated for presence and localization of claw lesion, concentrations of inflammatory markers, and abomasal rolling as therapy. At least one claw lesion was diagnosed in 46.4% of cattle. There was no association between laterality of claw lesion and LDA. Presence of claw lesion or oral drench and/or analgesic treatment did not have an effect on occurrence of relapse. A high number of cattle was diagnosed with both LDA and claw lesions. Focus should lie on preventing painful claw lesions in the dry and the early post-partum period. The high recurrence rate after abomasal rolling suggests that abomasal rolling should only be considered as a therapy for temporary relief, and surgical procedures should be discussed with farmers.

Abstract The relative bioavailability of trace minerals may vary between the sources and impact the animal performance. The study was carried out to evaluate the effect of TM source (Cu and Zn) on the liver concentration and performance of Nellore cattle supplemented in the growing phase during the transition between dry to rainy season. A hundred and twenty Nellore young bulls (BW = 349.72 ± 24 kg; 24 months), blocked by BW, were assigned randomly to twelve paddocks (six paddocks/treatment and 10 animals/paddock). Animals grazing Urochloa brizantha cv. Marandu and supplemented at 5 g/kg BW with soybean meal, corn and mineral mix (250 g/kg of CP and 650 g/kg de NDT, natural matter basis). Supplements consisted of 40 mg Cu and 148 mg Zn/kg DM from either inorganic TM (ITM) or hydroxy TM (HTM) Intellibond® sources. Liver samples were collected at the beginning and end of the study (three animals per paddock). Animals were weighed at each period (30 days) during three periods. Period was used as a REPEATED measurement for BW and values of initial BW as independent covariates for all variables. Paddock was considered experimental unit. Data were analyzed by ANOVA using PROC MIXED, SAS 9.4. The animals supplemented with HTM had higher (+0.037 kg/day) general ADG (day 0 to 90; P = 0.012), with 0.469 and 0.506 kg/day to ITM and HTM, respectively. Final BW (day 90) from animals fed HTM was 5.13 kg higher than ITM (391.97 vs. 397.11 kg BW; P = 0.030). No differences were found in the liver concentrations of Cu and Zn between ITM or HTM (P ≥ 0.288). Cu and Zn from HTM improve the performance of animals supplemented in pasture compared to ITM sources.

Main Effects

Abstract Lameness is a welfare issue and is the most common involuntary reason for culling pigs. Study objectives were to compare objective measures of lameness to gait score and assess effects of dietary chelated trace minerals in finisher pigs. The study was a 2 x 2 factorial arrangement consisting of naturally- occurring lame vs healthy pigs and 2 dietary treatments: 1) metal methionine hydroxy analogue chelate (MMHAC) supplied as MINTREX® Zn-Cu-Mn (Novus International, Inc.) supplemented at 80-10-20 mg/kg diet; and 2) sulfates Zn-Cu-Mn supplemented at 120-20-40 mg/kg diet. The study consisted of 4 groups of pigs (50-70 kg; 8 lame/8 non-lame per group) staggered one month apart. Dietary treatments were fed 53d. Measurements included gait scoring (0-4) and a panel of serum biomarkers (P2CP, CTX2, C2C, CTX1, osteocalcin) and were measured at baseline, d28 and d53. Serum biomarkers included bone synthesis (osteocalcin), bone degradation (CTXI), cartilage synthesis (P2CP), and cartilage degradation (C2C, CTX2) as well as the ratio of synthesis/ degradation for a total of 8 biomarkers. Proc Mixed GLM procedure of SAS was used and means were determined using a Tukey test. The main effects of healthy vs lame and dietary treatment were significant, but no diet x lameness interactions were observed. Lame pigs had elevated CTX2 (P< .01), C2C (P=.02) and tended to have reduced ratio of P2CP:CTX2 (P=.09) compared to healthy pigs. MMHAC increased P2CP (P=.01) and P2CP:CTX2 ratio (P=.03) in both healthy and lame pigs compared to sulfates. These findings demonstrate that biomarkers can distinguish mildly lame pigs (average score of 1) from healthy pigs and lower concentrations of MMHAC vs commercial level of sulfates increased cartilage synthesis and the ratio of cartilage synthesis/degradation in both lame and healthy pigs.
