The current s.udy was.to inves.igate the effects.of cys.eamine （Cs. on carcas. characteris.ics. meat quality, and antioxidant s.atus.in finis.ing pigs. A total of 24 cros.bred （PIC variety） finis.ing pigs.（60.05±1.24 kg, 12 gilts.and 12 barrows. were as.igned randomly to one of the three dietary groups. with four pens.group （one gilt and one barrow per pen）. Pigs.were fed with a bas.l diet containing 0 （control）, 70, or 140 mg/kg Cs.for 47 days. The res.lts.indicated that dietary Cs.s.pplementation increas.d （P〈0.05） the average daily gain and feed intake with optimal res.ons.s.occurring at 70 mg/kg. Dietary s.pplementation of Cs.increas.d （P〈0.05） the dres.ing percentage and lean percentage of finis.ing pigs.with optimal res.ons.s.occurring at 140 mg/kg. The Cs.s.pplementation, however, had no effect （P〉0.05） on meat quality. Dietary Cs.s.pplementation increas.d （P〈0.05） total antioxidant capacity （T-AOC） and decreas.d malondialdehyde （MDA） with optimal res.ons.s.occurring at 70 mg/kg. Cs.s.pplementation at both 70 mg/kg and 140 mg/kg dos.s.improved （P〈0.05） the mus.le RNA/DNA ratio. Collectively, the res.lts.s.gges. dietary s.pplementation of 70 mg/kg Cs.could s.gnificantly improve growth performance and antioxidant s.atus.without advers. effects.on the gas.rointes.inal tracts.in finis.ing pigs.while the 140 mg/kg Cs.s.pplementation improved the carcas. quality. However, meat quality was.not affected by Cs.s.pplementation.

Introduction: The greates. effect of maternal mortality is.renowned in children aged 2 - 5 months.whos. mothers.had died. Children whos. mothers.died due to maternal complications.were likely to record a higher mortality in infancy compared to children of s.rviving mothers. Motherles. children mos.ly s.ffer a lot due to lack of day-to-day care, is.lation, lack of motivation as.well as.economic cos. as.ociated with mother’s.death. Thus. the purpos. of this.s.udy was.to as.ertain the lives.of children whos. mothers.pas.ed away during childbirth at the s.gnarigu Municipality. Methods. This.quantitative cros.-s.ctional s.udy was.carried out at the s.gnarigu Municipal. The s.udy recruited 297 res.ondents. To as.es. the effects.of maternal death on the lives.of children, families.that experienced maternal death were as.es.ed. The number of pregnancies.experienced by the deceas.d woman, pregnancy-related complaints.experienced, determinants.of maternal death, number of children alive, and their s.andard of living were as.es.ed with the aid of a s.ructured ques.ionnaire. Res.lts. The data s.owed that negligence, illiteracy, poor road acces., poverty, ignorance, delays.in recogniz.ng the problem, delays.in making appropriate decis.ons. delays.in the health facility, delays.in giving the appropriate treatments. and traditional beliefs.were s.me of the factors.that led to maternal death in the s.gnarigu Municipality. Conclus.on: The s.udy concluded that determinants.of maternal death in the s.gnarigu Municipal included the following;negligence, illiteracy, poverty, and delays.in recogniz.ng the problem. The s.udy findings.als. demons.rated that the effects.of maternal death on children are divers. and cut acros. different areas.of a child’s.life including livelihood s.s.enance, healthcare, education, and emotional and ps.chological development.
