Though, milk production has been quite low. Therefore, this study was carried out to investigate the factors affecting dairy cattle milk production in Badulla. Total of 500 dairy farmers were selected using multistage stratified and simple random sampling techniques. Milk production and socio-economic data were collected using a pre-tested structured questionnaire covering 15 divisional secretariats in Badulla. Data were analyzed for descriptive and inferential statistics followed by regression analysis. Results of the study revealed that the intensive dairy cattle farming is operated (87.14%) in up country wet zone. Jersey breed was the major breed (86.4%) accounting for 6.19 L/cow average daily milk production. The highest (10.89±1.73 L/cow/day) and lowest (3.17±0.38 L/cow/day) milk productions were reported in Haputhale and Mahiyangana, respectively. The best fitted multiple linear regression model predicted that R2 value of 62.91% daily milk production suggesting farmers experience, farmer’s age, number of milking cows, forage type, shed condition, concentrate feeding supplement, frequency of concentrate supplement, frequency of water supplement, calves feeding amount age at wean, feeding method of cow, mineral supplement and monthly income of the farmers were significantly (p<0.05) affected by the daily milk production of Badulla district. However, lack of high yielding cross breeds, less success rate in artificial inseminations, low quality pasture and seasonality in pasture production, poor milk collection network and low farmer gate price, high price of concentrates, and inadequate facilities for animals in the estate area were reported as key constraints which need to be properly focused on in future to increase milk production in Badulla district, Sri Lanka. \u0000 \u0000 Key words: Dairy cattle farming, milk production, factors, regression analysis.","PeriodicalId":14143,"journal":{"name":"International Journal of Livestock Production","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90701349","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 study was conducted to determine the effects of cattle genotypes and levels of concentrate supplements on cost effectiveness of feedlot beef production in a Complete Randomized Block Design in 3×4 factorial arrangements with 4 replications. Feeds were urea-treated rice straw (UTRS: 4%, w/w) and concentrates made from decorticated cottonseed cake (66%) and maize bran (34%). The experimental animals were Ankole (A×A: n=16), Ankole × Friesian (A×F: n=16) and Ankole × Sahiwal (A×S: n=16) steers. Proxy indicators used to determine profitability and likelihood of economic viability were Initial and Final values of carcass existing abattoir price (RwF 1800/kg beef); Break-even scenarios using What-if Analysis in Excel, 2010; and Gross Margin (GM). Results suggested that cost effectiveness of feedlot beef did not differ (p>0.05) by genotype; but they differed (p<0.05) by diets. It is concluded that beef feedlots using UTRS was marginally economical at 500 g/day of concentrate supplements. A policy incentive to reduce Breakeven Price (BEP) is suggested.

Besides, conventional livestock (beef, chicken, etc.) cannot satisfy the high demand in Cameroon. Hence, snail meat could be suitable alternative source of protein. Therefore, this article investigated the perception and identified the main determinants of land snail meat consumption in the Fako division (south-west region Cameroon). A multistage random sampling method was used to select a total of 211 respondents. Descriptive statistics has highlighted that snail meat is quite consumed in Fako with 76.30% of respondents. Majority of respondents where Christians (95.26%) and have their origin from south-west region (56.40%). Additionally, regression analysis has pointed out that snail meat consumption depends on marital status, household size, income, snail origin and religion. The amount of snail meat consumed was shown to be influenced by its price and price variation between seasons. At the end of this study, two recommendations were made: snail farming should be increased in order to reduce scarcity of snail during dry season as well as its price and educate the people coming from other region of Cameroon on the nutritional benefits of snail meat. \u0000 \u0000 Key words: Snail consumption, African garden snails, Cameroon.","PeriodicalId":14143,"journal":{"name":"International Journal of Livestock Production","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78532439","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}

Total of 300 eggs (100 eggs from each native, Sasso and Bovans brown) chicken were collected during winter of 2017 to evaluate some egg quality parameters of chickens reared at Yirgalem and Hawassa towns of Southern Ethiopia. The eggs were purchased from the householders and each egg was carefully broken on a glass sheet, and was analyzed for different quality traits. The results of the study indicated that the weight of the eggs highly varied between the genotypes and also within genotypes (between locations) the eggs of the native chickens weighed (45.20±5.53 and 39.30±4.04 g), while eggs of Sasso chickens weighed (56.40±7.07 and 56.00±7.2 g), whereas those of Bovans brown weighed (57.80±7.22 and 60.70±5.98 g) at Hawassa and Yirgalem towns, respectively. The results pertaining to the Haugh unit of the eggs (from Hawassa and Yirgalem) and of the native chickens was (74.91±15.78 and 82.55±3.82), while for Sasso chickens (86.50±11.07 and 87.04±11.10) and Bovans brown were (94.60±7.74 and 86.29±5.85), respectively.

The questionnaire reveals that farmers’ motives are not limited to immediate economic objectives. The farmers also aim to provide general information on agriculture and livestock farming. In doing this, they wish to regain the leading role in agricultural discourses and to improve society’s understanding of current agricultural practices with the overall objective of gaining wider societal acceptance of present-day livestock farming.
