Physical characteristics, chemical composition and in vitro digestibility of the silage mixtures were determined in a laboratory trial while the preference of cattle for the mixtures was evaluated using twelve Sokoto Gudali heifers in a cafeteria feeding trial. The experimental design adopted was the completely randomized design. Silage colour changed from white to yellow; smell from very pleasant to pungent; and texture from very firm to firm as the level of urea in the silage increased. The pH increased from 3.80 to 6.00 as level of urea in the mixture increased. Crude protein (CP) content of silage increased from 8.50 to 17.52% while acid detergent fibre (ADF) decreased from 34.13 to 30.90% as level of urea in the silage mixture increased. Organic matter digestibility (OMD) varied from 55.44 – 60.45%, and increased with addition of urea. Preference of zebu heifers for corn cob-cassava peel silage varied from 13.81 – 38.87%. Acceptability of silage reduced significantly as level of urea increased. Addition of urea to corn cob-cassava peel silage enhanced CP content and digestibility but physical attributes and acceptability of silage by cattle were adversely affected.","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121734613","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 diets contained 0, 25, 35 and 45% DBG in treatments T1, T2, T3 and T4 respectively. The experiment was in a completely randomized design (CRD) with each treatment being replicated three times. Fortnightly live weight, daily feed intake, feed cost and final carcass quality of pigs were recorded. Results showed that pigs fed T3 had significantly (P<0.05) higher live weight gain than other treatments during all the stages. However, pigs on T4 had significantly (P<0.05) higher feed intake (1.32 kg) than those on other treatments during the weaner stage. At the grower stage pigs fed on T3 had weight gain and feed conversion ratio (FCR) similar to the control diet. Back fat (1 st rib) thickness, dressing out percentage and carcass length in T3 diet was significantly (P<0.05) reduced. There was also a reduction of feed cost with increased inclusion of DBG; with diet T3 having the highest gross margin and T2 had the lowest. It is concluded that in growing pigs the inclusion of 35% DBG in pig diets gives highest economic return without affecting performance.","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131050776","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}

Thirty three (33) Yankasa ewes aged 1.5- 3 years, 21 to 26 kg body weights, with body condition score of 2.5- 3.5 were used in this study. Ewes were randomly allocated into 5 groups, Group 1 (ewes treated with Lutalyse® [YK-LT], n= 7), Group 2 (ewes treated with estroPLAN® [YK-ET], n= 7), Group 3 (ewes treated with EAZI- BREED™ CIDR® [YK-CD], n= 5), Group 4 (ewes treated with Fluorogestone acetate-45® [YK-FG], n= 7) and Group 5 (Control [YK-CT], n= 7). Natural breeding was carried out using sexually active rams for 5 days following progestagen withdrawal and second prostaglandin administration. 100% oestrus response was observed in YK-ET, YK-CD and YK-FG, respectively. Time to onset of oestrus was 68.23 ± 17.28 h in YK-LT, 49.29 ± 4.5 h in YK-ET, 33.48 ± 8.6 in YK-CD, 53.27 ± 12.3 in YK-FG and 39.2 ± 13 in YK-CT. Duration of oestrus was longest in YK-LT (51.35 ± 13.9 h) and shortest in YK-CT (17.2 ± 6.9 h). Mounts per oestrus period was highest in YK-CT (26.9 ± 4.8) and lowest in YK-ET (14.3 ± 4.3). Conception rate was 100% in the YK-LT, YK-ET, YK-CD groups respectively. It is concluded that estroPLAN® and CIDR® offered the best results in synchronizing oestrus in Yankasa ewes and may be used by farmers to enhance productivity.","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130725306","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}

A group comprised of 100 multiparae Nellore cows was submitted to a resynchronizing protocol: on day 0 the subjects received the Bovine Intravaginal Device with 1,0g of progesterone (P4), associated with intramuscular administration of 2,0mg of estradiol benzoate (IM); on day 8, the Bovine Intravaginal Device (DIB ® ) was removed, and 1,0mg of estradiol cypionate, 0,15mg of prostaglandin F 2α and 300 UI of equine chorionic gonadotropin were administered; on day 10, fixed-time artificial insemination was conducted (FTAI ). The subjects were then randomized into Control Group (n=50) and Treated Group (n=50), of which the latter received 500mg of rbST on the eighth day of the protocol. Sixty days after the fixed-time artificial insemination, pregnancy diagnoses were conducted via rectal palpation. Blood samples were taken to measure plasma concentrations of glucose, triglycerides and cholesterol. Pregnancy rates were statistically evaluated through Generalized Linear Models Theory, and their significance was tested through Analysis of Deviance. No difference was found between groups, pregnancy rates were 40% and 48% for control and treated groups, respectively. Cholesterol plasma concentrations were also not affected by the treatment with rbST. There were significant increases in serum glucose and triglycerides between groups. The administration of rbST to multiparae Nellore cows, in a single dose, did not statistically interfere in the pregnancy rates. The resynchronization of estrus and re-insemination had a positive effect in cumulative pregnancy rates.","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127326846","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}
