“…Bünzen et al (2009) compared the total collection and fecal indicator methods and did not verify differences between them for the coefficients of apparent and true digestibility of the phosphorus. Rocha Junior et al 2015and Santana et al (2017), in a study with swines, did not found any difference between the total collection and the faecal indicator methodologies. The results suggest that both methods can be used to determine the true digestibility of calcium.…”

“…However, the content of AIA in grains is low and the amount supplied in the diets is not enough to act as an indicator. Thus, eventually, external sources of AIA (Celite ™, sand and silica) can be added to diets to improve the accuracy of estimates, being also considered as external indicator, as assessed by Salguero Cruz et al (2014), Rocha Junior et al (2015 and Santana et al (2017). Carvalho et al (2013) compared different methods of analysis of acidinsoluble ash with the total collection method to the determination of metabolizable energy of corn to birds.…”

“…One of the problems in feeding pigs is related to the digestibility of minerals, because in the main ingredients of the diet, corn and soybean, many of them are complexed with phytic acid (SELLE et al, 2009), making it necessary to include some inorganic source in the feed. Among the sources that can be used in calcium supplementation are those from calcareous rocks (limestone and phosphates), the more often used in feed because they are found in greater abundance and are of low cost (SANTANA et al, 2017). However, the physical and chemical characteristics of the source may negatively affect the digestibility and consequently the availability of the mineral.…”

SUMMARY The objective of the study was to determine the digestible calcium from different sources by direct and indirect methods. Thirty castrated male pigs were used, distributed in randomized blocks, in six treatments: 1- Calcitic limestone; 2-Dicalcium phosphate powder 18%; 3- Dicalcium phosphate powder 20%; 4- Dicalcium microgranulated phosphate 18%; 5- Monodicalcium microgranulated phosphate 20%; 6- Monodicalcium microgranulated phosphate 21%, with six replicates and one animal per experimental unit. A basal diet was formulated to meet the nutritional requirements of the animals, except for calcium (0.06%) and the evaluated sources replaced the basal diet in order to provide 0.45% of total Ca. At the same time, two stool collection methods were evaluated: total collection and fecal indicator. The animals were housed in metabolism cages for 12 days to collect feces and urine to determine the calcium values used to estimate digestibility coefficients and digestible calcium. The total collection method and the faecal indicator method did not affect the true digestibility coefficient of calcium. The calcium digestibility of the microgranulated dicalcium phosphate 21% (MM21) was superior in comparison with the other calcium sources evaluated by the indirect method in the present study. The average values of true digestibility of the calcium sources, in percentage, were: calcitic limestone: 82.47; dicalcium phosphate powder 18%: 80.87; dicalcium phosphate powder 20%: 85.65; dicalcium microgranulated phosphate 18%: 81.65; monodicalcium microgranulated phosphate 20%: 84.15; and monodicalcium microgranulated phosphate 21%: 88.35. The two methodologies can be used to determine the digestibility of calcium.

“…However, literature is limited on studies evaluating different sources of calcium in sow diets, in which blood calcium concentration is analyzed in their litters. Santana et al (2017) evaluated different calcium sources (limestone, monodicalcium phosphate, calcined bone meal, and oyster meal) in starter pig diets and found no differences in serum calcium concentration (≅10.60 mg dL −1 ). This result was also reported by Santos et al (2021), who studied dietary L. calcareum (2.35%) as calcium source for piglets.…”

“…Lower plasma calcium concentration, compared with our results, was reported by Barrilli et al (2017) in sows (days 14 and 21 of lactation) fed organic (≅5.5 mg dL −1 ) and inorganic (≅5.6 mg dL −1 ) calcium source. According to Santana et al (2017) and Santos et al (2021), plasma calcium concentration should range from 8 to 12 mg dL −1 . However, plasma calcium concentration is constant due to physiological mechanisms of mineral homeostasis (Santos et al, 2021).…”

Non-ruminantsFull-length research article Addition of calcitic seaweed in the diet of sows positively affects the number of live-born piglets and milk parameters ABSTRACT -This study was conducted to assess the effects of maternal dietary calcitic seaweed (CSW) on performance and blood metabolites of sows, and on performance, blood metabolites, intestinal microbiota, and parameters of gastrointestinal tract and bone of litters. On d 21 (post-insemination), non-pregnant sows were removed from the trial, remaining 19 sows in control group (without CSW) and 16 sows receiving CSW. Then, a total of 35 sows were allocated in a randomized block design with two treatments: control diet with calcitic limestone plus dicalcium phosphate (CTL) or CTL plus 0.4% CSW. In gestation, sows were fed twice a day (07:00 and 15:00 h) to reach an intake of 2.5 kg animal −1 day −1 divided into two equal meals. On parturition day, sows were offered only 0.5 kg feed animal −1 . Throughout lactation, sows were fed three times a day (≅7 kg animal −1 day −1 ). All diets were provided as mash. Results suggested that sows fed CTL had litters with lower body weight at birth compared with those fed CSW. Sows fed CSW had 14.28% more live-born piglets and lower stillborns. Piglets from sows fed CSW showed greater calcium concentration on d 14 after birth than those from sows fed CTL. Sows fed CSW showed better milk chemical composition and an increase of 27.16% in milk production compared with those fed CTL. Piglets from sows fed CSW had an increase in cecum content in the Enterobacteriaceae count. This study showed that adding 0.4% CSW in the diet of pregnant and lactating sows as an organic calcium source positively influences the number of live-born piglets and the percentage of stillborns. In addition, milk composition and production are also improved without affecting piglets' biological response.

Context Lithothamnion calcareum is a calcitic seaweed (CS), rich in calcium (Ca) and other minerals, with potential for use in piglet feeding. Aim The aims were to compare L. Calcareum (CS) with calcitic limestone (CL) as a source of Ca for use in piglet feeding for effects on total tract digestibility and daily balance of Ca, growth performance and serum variables, and to assess solubility of Ca sources through in vitro testing. Methods In Expt 1, an availability assay was performed on 24 crossbred male piglets with initial average body weight (BW) of 15.17 ± 0.70 kg in a randomised complete block design with six replicates of four treatments and one piglet per experimental unit. The starter dietary treatments were: basal diet with minimal amount of Ca (0.068%); diet with low Ca (0.018%); and two diets containing either CL or CS to provide 0.82% total Ca. In Expt 2 (growth performance), 96 crossbred male piglets, with initial average BW of 6.01 ± 0.70 kg were assigned in a randomised complete block design with eight replicates of three treatments (CL, CL + CS, or CS) and four piglets per experimental unit, assessed over pre-starter phases I and II and the starter phase. Key results In Expt 1, Ca source did not influence (P > 0.05) apparent and true digestibility or daily balance and concentration of Ca in the piglets. In Expt 2, no significant differences (P > 0.05) existed for growth performance during the pre-starter I and II phases, although a trend (P ≤ 0.1) was evident for final BW, daily weight gain and feed conversion ratio (FCR) during the pre-starter II phase. Piglets fed CL showed a reduction in FCR during the starter phase (P = 0.02) and for the total period (P = 0.007). Final BW and daily weight gain did not differ between CL and CS diets during the starter phase or for the total period. No effect (P > 0.05) was observed of Ca source on Ca and phosphorus concentrations in serum. CS had a solubility 1.9 times higher than CL. Conclusion Piglet performance parameters were generally similar for diets including CS and CL as a source of Ca. Implications Based on the evaluation criteria used in these experiments, L. calcareum has potential to replace calcitic limestone as an alternative source of Ca.
