“…This result is in agreement with the value that has been established for this ratio (around 2:1) for the normal metabolism of these minerals (McDowell 1992; Underwood & Suttle, 1999). In the present study, the net Ca requirement for gain for the Santa Inês lambs was lower than that reported by Geraseev et al (2001), who studied the same breed. The authors of the present study and Geraseev et al (2001) obtained similar P requirements for the Santa Inês lambs.…”

“…However, our study revealed differences in the concentration of these minerals with increases in BW. This result agrees with the findings from previous studies (Kellaway, 1973;Thompson et al, 1988;Geraseev et al, 2001;Wiseman et al, 2009). For the mineral proportions in the body to remain constant, it would be necessary for the muscle, bone and fat deposition to increase at the same rate and in the same proportion; however, this is not the case (Berg & Butterfield, 1976;Sainz, 2000;Lawrence & Fowler, 2002).…”

Mineral requirements for growth of wool and hair lambs

The present study was conducted to determine the body composition and the mineral requirements for growth of wool and hair lambs. A total of 34 castrated lambs with an initial body weight (BW) of 19.9±0.8 kg were used; 17 of these lambs were of the genotype Ideal × Ile de France and 17 were Santa Inês. Ten lambs (5 of each genotype) were slaughtered at the beginning of the experiment to establish their initial body composition. The remaining lambs were assigned to one of three diets (40% roughage and 60% concentrate, 60% roughage and 40% concentrate, or 80% roughage and 20% concentrate) in a 2 × 3 factorial arrangement of treatments. All of the diets were provided ad libitum. When the group under 40% roughage and 60% concentrate reached 35 kg BW, all of the animals were slaughtered. Linear regressions were used to determine the relationship between the shrunk BW and the empty body weight (EBW) for each genotype. These equations were compared and revealed differences between the genotypes. The allometric equations were calculated using the relationship between the amount of minerals and the EBW. The equations of a given mineral for each genotype were compared to verify if they were statistically different. The equations for calcium, phosphorus, magnesium and sodium differed between genotypes. The same equations were used to estimate the major body mineral composition per kilogram of EBW. The net requirement for gain of the fleece-free Ideal × Ile de France lambs ranged from 7.77 to 6.80 g Ca, 4.54 to 4.14 g P, 0.30 to 0.27 g Mg, 1.18 to 1.07 g K and 0.84 to 0.76 g Na per kg BW gain, and the requirements of the Santa Inês animals ranged from 9.57 to 8.37 g Ca, 5.39 to 4.91 g P, 0.36 to 0.33 g Mg, 1.18 to 1.07 g K and 0.90 to 0.81 g Na per kg BW gain for the lambs weighting 20 to 35 kg. Santa Inês lambs showed higher requirements for Ca, P, Mg and Na.

“…Devido à diversidade de funções que exercem no organismo, são importantes em diversos processos de bioquímica fisiológica (Geraseev et al 2001). Os cloretos são os ânions mais abundantes no compartimento extracelular, e a concentração no plasma e a eliminação destes íons são usualmente concomitantes com as do sódio.…”

The sheep industry in Brazil is an important economic activity, and with the increasing global demand for sheep meat there is a great interest in the monitoring of the herd health, and serum reference ranges are basic tools for veterinary clinical pathology assays. Mineral elements correspond to 2-5.5% of the body of vertebrates, holding different functions in their physiology. The objective of this study was to obtain reference intervals of the electrolytes magnesium, phosphorus, chloride and calcium for the Dorper and Saint Ines sheep breeds. Sera samples were collected from 487 clinically healthy sheep, 146 from Dorper and 341 from Santa Ines breed. Electrolytes were measured using commercial kits. Data were analyzed taking the race, sex and age variables in account, and reference ranges were established. The results revealed significant statistical differences in reference ranges obtained for the electrolytes calcium and magnesium concerning the variable race, and for the electrolyte phosphorus in the variable age and, when compared with reference values already published, proved the existence of significant differences.

Chlordecone (Kepone) (CLD) is a highly persistent pesticide which was extensively used in the French West Indies; high levels of CLD can still currently be found in large agricultural areas. As CLD transfers from soil to animals mainly via involuntary ingestion, the consumption of foodstuffs derived from animals raised in contaminated areas may significantly contribute to exposure of humans to CLD. The present study was designed to test the efficacy of two different activated carbons (ACs) sources in limiting CLD transfer from soil to animal. Three soils (ASs) were prepared according to the OECD guideline 207. One standard soil (SS) lacking AC, and two modified preparations of SS supplemented with 2% coconut-based activated carbon (ORBO), SSO or with 2% lignite-based one (DARCO), SSD. All three soils were spiked with 10 μg of kepone per g of dry matter and aged for three weeks. This study involved 15 goat kids randomly assigned to the 3 experimental groups (n = 5/ group), which were fed the experimental matrices at an exposure dose of 10 μg CLD per kg of body weight per day. After 21 d of oral exposure, CLD in adipose tissue and liver were analysed by LC-MS-MS. A significant decrease of 63.7% and 74.7% of CLD concentrations in adipose tissue and liver, respectively, were obtained from animals exposed using SS containing DARCO as compared to those receiving only SS. Decreases in CLD levels of 98.2% (adipose tissue) and 98.7% (liver) were obtained for animals exposed using SS containing ORBO. This study leads us to conclude that (i) the presence of AC in CLD-contaminated soil strongly reduces CLD bioavailability, and (ii) the efficacy depends on the nature and characteristics of the AC used.
