Welfare indicators associated with feed conversion ratio and daily feed intake of growing-finishing pigs C. R. Pierozan, C. P. Dias, D. Temple, X. Manteca, C. A. da Silva Animal Production Science, 2021 Context Understanding the welfare indicators that affect animal performance can facilitate modifications that improve both animal welfare and profitability. Aims A cross-sectional study was conducted to investigate the prevalence of animal welfare indicators and quantify their possible associations with feed conversion ratio (FCR) and daily feed intake (DFI) of growing-finishing pigs (Sus scrofa). Methods Data from 46 farms were collected. The herds ranged from 360 to 2500 pigs, which were aged between 75 and 173 days, and were managed on an all-in all-out basis. The welfare indicators were evaluated once on each farm using the methodology of the Welfare Quality® assessment protocol for pigs. Multiple linear mixed models were used to assess the associations of welfare with FCR and DFI according to the production stage at which the pigs were evaluated on the farm. Key results The welfare indicators with the highest average prevalence were frequency of coughing (35.7%), moderate bursitis (31.1%), and moderate and severe soiling with manure (18.8 and 27.7% respectively). Most of the remaining indicators related to poor welfare had prevalence values of less than 1%. The mean prevalence of positive social behaviour (such as sniffing/nosing/licking) was 14.4% and that of negative social behaviour (NSB; such as aggressive interactions) was 3.1%. The average space allowance (measured in 460 pens) was 1.04 ± 0.13 m2/pig (ranging from 0.78 to 1.36 m2/pig). Better FCRs were associated with a low prevalence of NSB (P < 0.05), a low prevalence of coughing (P < 0.01), absence of lameness problems (P < 0.001), and small space allowances (P < 0.05). Lower DFI values were associated with a low prevalence of NSB (P < 0.05), a high prevalence of moderate hernias (P < 0.01), a low prevalence of other active behaviours (such as eating and drinking) (P < 0.001), and a high prevalence of animals with wounds on the body (P < 0.05). Conclusions Few indicators related to the impairment of welfare were detected with a high prevalence, and the results suggest that the conditions related to poor welfare were associated with an impairment in animal performance. Implications The results of this study can provide the industry with comparative information to promote improvements in pig welfare. Some welfare indicators could be used on farm as predictors of performance variables; however, these indicators need validation.
Dietary xylanase and live yeast supplementation influence intestinal bacterial populations and growth performance of piglets fed a sorghum-based diet Gemma González-Ortiz, Marco A. Callegari, Pete Wilcock, Diego Melo-Duran, Michael R. Bedford, Hilário R.V. Oliveira, Marcos A.A. da Silva, Carlos R. Pierozan, Caio A. da Silva Animal Nutrition, 2020 This study was to evaluate the effect of xylanase supplementation and the addition of live yeast, Saccharomyces cerevisiae, on growth performance and intestinal microbiota in piglets. One hundred and eighty commercial crossbred 23-d-old piglets (PIC 417) were sorted by initial BW and allocated to 3 treatments: control (CTR) diet, CTR diet supplemented with xylanase at 16,000 birch xylan units/kg (XYL) and XYL diet supplemented with live yeast (2 × 1010 CFU/g) at 1 kg/t (XYL + LY). Each treatment had 10 replicates, with 6 animals each. A sorghum-based diet and water were available ad libitum for 42 d of the study. Average daily gain (ADG) and average daily feed intake (ADFI) were measured from 0 to 42 d (23- to 65-d-old) and feed conversion ratio (FCR) calculated. At the end of the study, bacterial identification through 16S rRNA (V3 to V4) sequencing of the ileal and caecal digesta from one piglet per replicate was performed. No treatment effects were observed on ADFI. Pigs offered the live yeast in addition to the xylanase had increased ADG compared with those supplemented with xylanase alone (XYL + LY vs. XYL; P = 0.655). FCR was improved with XYL and XYL + LY compared with CTR (P = 0.018). Clostridiaceae counts in the ileum tended to reduce by 10% with XYL and 14% with XYL + LY compared to CTR (P = 0.07). XYL and XYL + LY increased the counts of Lactobacillaceae in the caecum compared with CTR (P < 0.0001). Dietary supplementation of live yeast combined with xylanase improved growth performance and microbial balance of piglets during the nursery phase.
Herd-level factors associated with piglet weight at weaning, kilograms of piglets weaned per sow per year and sow feed conversion C.R. Pierozan, M.A. Callegari, C.P. Dias, K.L. de Souza, J. Gasa, C.A. da Silva Animal, 2020 To understand the production factors that affect conclusive parameters of sow herd performance can improve the use of the resources and profitability of farm. The objective of this study was to identify associations and quantify the effects of a set of factors related to piglet weight at weaning (PWW), kilograms of piglets weaned per sow per year (kgPWSY) and sow feed conversion (SFC). Data from 150 farms were collected, for a total study population of 135 168 sows, including gilt replacement, breeding (mating), gestation and farrowing/lactation phases. A questionnaire focusing on reproductive performance, management, facilities, feeding, health and biosafety was administered. Multiple linear regression models were used to assess associations among factors with each of the three dependent variables. Increased duration of lactation was positively associated with PWW, kgPWSY and SFC. The increase in the number of live born pigs per litter was positively associated with kgPWSY and with SFC. Farms with higher PWW had farrowing room humidifiers, did not surgically castrate male piglets and used quaternary ammonia compounds for farrowing room disinfection. Farms with higher kgPWSY used lined ceilings in farrowing rooms and winter feeds with higher CP percentages in gestation; they also had more farrowings per sow per year. Sow feed conversion was worse in farms with partly slatted floors during gestation, in farms feeding lactating sows six times a day or ad libitum and farms with a higher sow-handler ratio. This study indicates that farms can increase PWW and kgPWSY and improve the SFC by changing one or more management, biosafety and feeding practices or facilities as well as by focusing on improving several performance parameters, particularly increasing the duration of lactation and the number of live born pigs per litter.
Brazilian panorama of pig breeding sector: A cross-sectional study about specific aspects of biosecurity, facilities, management, feeding, and performance Marco Aurélio Callegari, , Carlos Rodolfo Pierozan, Cleandro Pazinato Dias, Kelly Lais de Souza, Luciana Foppa, Josep Gasa, Caio Abércio da Silva, , , , , , and Semina Ciencias Agrarias, 2020 The objective of this study was to identify the degree of adoption of different production factors in commercial pig breeding farms in Brazil. Data were collected from 150 farms, totaling 135,168 sows, including general information, labor, genetics, biosecurity, facilities, management, feeding and productive performance for the year 2015. The farms were located in the South (42%), Southeast (45.3%) and Midwest (12.7%) of Brazil. The amplitude of the herds varied between 100 and 6,360 productive sows, with an average of 901. Their predominant profile was independent production with hired labor, an average of 88 sows per employee, facilities with more than 15 years and no reform in the last decade, and located less than 5 km from other units. Animal replacement was performed mainly by purchase and without adoption of a quarantine period. Predominated farms housed the sows in crates in the pre-mating period and in pens or crates/pens during gestation. Both solid and slatted floors were used in these phases, predominantly using concrete as material; the use of slatted floors (either concrete, metal, or plastic) predominated in the farrowing facilities. Gutter-type feeders that also operated as water drinkers were predominant in the pre-mating and gestation periods; in farrowing facilities wet-dry feeders were widespread. Two-thirds of the farms did not have a cooling system in farrowing facilities. For the piglets, the heating system above the animal (lamps and bell rings) prevailed to the detriment of heat floors. More than 60% of farms make their own feed and feed gestating sows once a day. Only 29.33% of the farms perform echography for diagnosis of gestation. Birth attendance was routine; however, one-third of the farms did not have attendance through the night. Batch weaning was practiced by 15.44% of the farms. More than half of the farms reported that they did not intervene in the colostrum supply of piglets born weak or small, but 95.33% piglets were transferred among litters considering their size and quantity. Teeth resection, tail docking, and surgical castration procedures were routine. The performance indexes were consistent with what is perceived by national surveys.
Producers’ knowledge and perception about environmental enrichment and materials used in pig farms Carlos Rodolfo Pierozan, Luciana Foppa, Edilson Dias Caldas, Andre Michelon, Gabriela Ruiz, José Vitor Silva Duarte, Camilo Cazetta Rodrigues Silva, Caio Abércio da Silva Revista Brasileira De Zootecnia, 2020 This study investigated the knowledge and perception of Brazilian pig producers in terms of environmental enrichment (EE) for pigs, the materials used, and the forms of presentation, identifying the single conditions that can improve their application on pig farms. A questionnaire was applied to 1340 farms – representing 7.4% of the farms and 12% of the sows in the country. The questions included descriptions of farms and respondents, their knowledge, judgments and level of interest in the use of [...]
Effect of stocking density and use of environmental enrichment materials on the welfare and the performance of pigs in the growth and finishing phases Edilson D. Caldas, André Michelon, Luciana Foppa, Sandra M. Simonelli, Carlos R. Pierozan, Julie G. N. Dario, José V. S. Duarte, Camilo C. R. Silva, Caio A. Silva Spanish Journal of Agricultural Research, 2020 Aim of study: To evaluate the effects of stocking density and the use of environmental enrichment (EE) objects on the welfare and the performance of pigs in the growing and finishing phases.Area of study: The southern region of Brazil.Material and methods: A total of 240 pigs, 120 immunocastrated males and 120 females, with an initial weight of 22.38 ± 2.38 kg and mean age of 65 days, were submitted to two stocking densities conditions (0.85 and 1.28 m²pig) with and without EE for 117 days. The experimental design was a 2×2×2 factorial (two categories, two densities, and two EE conditions), with six replicates. Performance variables and behavior were evaluated.Main results: For stocking density, there was a significant difference in the finishing phase from 148 to 161 days of age for the final weight (FW), average daily weight gain (ADWG), and feed conversion rate (FCR). For the EE factor, there was no difference in any of the phases or in the overall period. In the overall period, the higher availability of space improved the results of FW (140.56 kg vs 136.63 kg), ADWG (1.005 kg vs 0.974 kg), and FCR (2.05 vs 2.10). There was no effect of EE, stocking densities, or their interaction on the frequency of different behaviors of the pigs in the growth and finishing phases.Research highlights: There was no effect of interactions between enriched environments, stocking densities, and sex for animal performance and behavioral frequencies; however, differences between the factors were observed separately. The higher availability of space improved the results of FW, ADWG, and FCR.
Increased vitamin supplement to sows, piglets and finishers and the effect in productivity R.K.S. Santos, A.K. Novais, D.S. Borges, J.B. Alves, J.G.N. Dario, G. Frederico, C.R. Pierozan, J.P. Batista, M. Pereira, C.A. Silva Animal, 2020 With still limited information on vitamin requirements and considering that many commercial practices adopt dietary vitamin levels above the values suggested by nutritional tables, this study aimed to assess the effect of administering vitamin supplementation to sows in gestation and lactation and to their litters on the reproductive performance and body condition of the sows and on the performance and immune profile of the litters until slaughter. The trial was split into two phases. The first phase used 104 sows, assigned to be randomized to blocks according to parity, submitted until 21 days of lactation to two treatments: control-standard (standard levels of vitamins) and test-elevated (elevated levels of vitamins). Each sow and its respective farrow were considered an experimental unit. The sows underwent evaluations of body condition score, back fat thickness and reproductive performance. In the second phase, 60 barrows and 60 gilts at 21 days of age and mean initial weight of 5.33 ± 1.5 kg until slaughter at 164 days of age. The piglets were assigned to randomized blocks according to the weight and sex of the animals in a 2 × 2 factorial model, with 10 replicates per treatment, where a pen with three animals represented the experimental unit. Following the same treatments of the first phase, the piglets were evaluated for daily weight gain, daily feed intake, feed conversion, mortality rate and humoral immune response. Vitamin supplementation had no positive effects on the reproductive parameters or body composition of sows. However, it positively impacted the performance of the litters in the early nursery stage, but did not lead to superior effects on the immune responses to vaccination against circovirus or mycoplasma.
