The aim of thisstudy was to investigate the effect of cracked corn grain as a source of moisture absorbent andenergy in a wet soya waste based total mixed ration silage on goat performance. Ten growing goatswere assigned to two feeding treatment groups for 84 days. Goats in Group 1 received Napier grass(Pennisetum purpuerum) ensiled with 30% soya waste (w/w) and 8% molasses (w/w) (T1) ascontrol, and Group 2 received same grass ensiled with 30% soya waste (w/w) and 15% crackedcorn grain (w/w) (T2). All goats received their respective silage ad libitum after 2 months offermentation. The pH in T1 silage was 4.1, while pH in T2 silage was 4.0. Goats fed T2 diet showedhigher intakes of dry matter, organic matter and metabolisable energy than those of goats fed T1diet, while it was observed vice versa for neutral detergent fibre intake. However, there was nodifference in average daily gain and feed conversion ratio between two treatment diets. Results ofthis study indicate that cracked corn grain, as a source of moisture absorbent and energy, can beused successfully in wet soya waste based total mixed ration silage for growing goats.","PeriodicalId":17457,"journal":{"name":"Journal of Tropical Resources and Sustainable Science (JTRSS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72760219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-four does were treated with 14 dayssynchronisation followed by visual observation of oestrus expressions (standing heat (SH),mounted by other buck but not standing (MBNS), vocalization (VC), tail swaging (TW), andsniffing of the genital of other buck (SGB)) and blood sampling twice daily up to 72 hours followingControl Internal Drug Release (CIDR) removal. PBRP data was recorded for evaluation whichincluded pregnancy rate (PR), abortion rate (AR), mortality rate (MR), litter size (LS), litter birthweight (LBW) and gestation length (GL). Result revealed that there was no significant effect(P>0.05) of parity and BCS on OE, PBRP and progesterone concentration except for birth weightwhich had been affected by parity. Based on observation of OE of SH, it was found that accuracyof pregnancy prediction was up to 50%. Analysis of OE established reliability of OE in wassequence from SH>SGB>TW>MBNS>VC and onset of oestrus began approximately 33h post toCIDR removal. Analysis of PBRP shown parity?2 had heavier birth weight in single litter size thanparity?3 which was associated with no MR. Progesterone concentration indicated all of the doeswere on oestrus and highly susceptible as early as 48 h post to CIDR removal. In conclusion, thisstudy demonstrated that both non-genetic factors; parity and BCS are very poor in determining theeffect of OE, PBRP and P4 concentration due to limitation of sample size and greater influences ofexternal factors such as weather, extreme environmental condition and farm management. It isrecommended to improve program in future by focusing on enhancing the fertilization rate andreducing embryonic loss for optimum conception rate.","PeriodicalId":17457,"journal":{"name":"Journal of Tropical Resources and Sustainable Science (JTRSS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91347215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Groundwater is often contaminated by the process ofindustrial development and suburbanization that has gradually advanced over time without anyconcern for environmental consequences. The objective of this study is to analyse the groundwaterquality of shallow dug wells in parts of Tanah Merah district by conducting quality assessment ofgroundwater using WHO and MHO guide lines. Groundwater samples were collected from dugwells uniformly spread out across the study area to investigate the major ion chemistry of thegroundwater as well as physical parameter. The major ion being investigated are sodium,magnesium, calcium, potassium, sulphate, nitrate, chloride and bicarbonates. Various methods havebeen were employed to determine the major ions concentration in the samples such as atomicabsorption spectrophotometer for cations, gravimetric method for sulphates, titration method forchloride and bicarbonates and colorimetric method for nitrate ion. From the analysed data’s, mostwells are safe for drinking purpose although quite a small amount of ion concentration has surpassedthe permissible limit set by WHO and MOH. The graphical presentation of major ion chemistryaids in identifying two types of groundwater. Ionic species such as Na-K-HCO3 and mixed typewaters are likely to occur in the groundwater system. The analysed major ions concentrationsindicates that majority of the shallow dug wells reported adequate or lower values compared topermissible limit which are safe and can be utilized for various domestic purposes includingdrinking. Several recommendations has been suggested to proliferate the groundwater quality suchas strictly monitoring and supervising the dissipation of waste such as pesticides, industrial effluentand domestic sewage into the aquifer.","PeriodicalId":17457,"journal":{"name":"Journal of Tropical Resources and Sustainable Science (JTRSS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84640720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hourly trend of TVOC and CO2 concentrations with peakconcentrations were observed in the morning (8 a.m.) due to outdoor traffic emission which greatlyinfluenced the indoor pollutants variation.

Atotal of 300 quails were randomly picked and the breastbone length, chest girth, body weight,body length, shank length and drum length were measured for the morphology. Then, 270 eggs ofCommercial and White Texas strains were used to test the hatchability rate (n=150) and eggquality (n=120). The ratio of the parents of the quails between male and female of each type ofstrain were 1:3. The cleanliness, shape, weight, and texture of the eggshell were observed,weighed and measured. The eggs were incubated for 17 days (37.6 °C, 65% humidity). The shapeindex, egg weight, egg volume and eggshell surface were weighed and measured for the exteriortrait of eggs. For interior trait, the albumen index, Haugh units, and internal quality units (IQU)were measured. Significant findings were observed in all of the features (P<0.05), except for thewing length in morphology. For hatchability rate, there was a high significant in the percentage ofhatchability of incubated eggs, hatchability of fertile eggs and smoothness texture of the eggshell.In egg quality there was high significant in Haugh unit but low significant internal quality unit.The significant variability might be due from the genetic information that inherited from theparents. The IKTA and White strains were not the same in morphology, hatchability rate andinterior trait of eggs but same exterior trait of eggs. In conclusion, this research is important ingiving information about Japanese quail strain in Malaysia and more genetic study should be donein the future to determine good strain and increase understanding about quail strain.","PeriodicalId":17457,"journal":{"name":"Journal of Tropical Resources and Sustainable Science (JTRSS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76686319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
