Measuring total factor productivity on Irish dairy farms: a Fisher index approach using farm-level data Irish J. Agric. Food Res. (IF 1.5) Pub Date : 2020-11-21 M. McCormack, F. Thorne, K. Hanrahan
This paper presents a Fisher index measure of the total factor productivity (TFP) performance of Irish dairy farms over the period 2006–2016 using the Teagasc National Farm Survey (NFS) data. The removal of milk quotas in 2015 has led to an increase of over 30% in dairy cow numbers since 2010, and although suckler cow numbers have dropped slightly, the total number of cows in Ireland reached an all-time

Yield of binary- and multi-species swards relative to single-species swards in intensive silage systems Irish J. Agric. Food Res. (IF 1.5) Pub Date : 2020-04-01 T. Moloney, H. Sheridan, J. Grant, E.G. O’Riordan, P. O’Kiely
Abstract Binary- and multi-species sown mixtures may increase herbage yield and/or reduce inorganic nitrogen (N) requirement compared to perennial ryegrass (PRG) (Lolium perenne L.) swards. A split-plot design was used to compare yields of binary- and multi-species mixtures to single-species swards of three grasses and red clover managed for intensive silage production under varying N application rates

Meat quality characteristics of high dairy genetic-merit Holstein, standard dairy genetic-merit Friesian and Charolais x Holstein-Friesian steers Irish J. Agric. Food Res. (IF 1.5) Pub Date : 2020-03-13 M. McGee, M.G. Keane, R. Neilan, P.J. Caffrey, A.P. Moloney
Abstract The increased use of Holstein genetic material in the Irish dairy herd has consequences for beef production. In all, 42 spring-born steers [14 Holsteins (HO), 14 Friesian (FR) and 14 Charolais × Holstein-Friesian (CH)] were reared to slaughter at between 26 and 37 mo of age. Carcass weight was higher and the lipid concentration of m. longissimus thoracis et lumborum was lower (P < 0.05) for

Production of probiotic Bulgarian yoghurts obtained from an ultrafiltered cow’s milk Irish J. Agric. Food Res. (IF 1.5) Pub Date : 2020-03-03 S. Kodinova, M. Dushkova, M. Miteva-Petrova, V. Yanakieva, S. Petrov, Z. Denkova
Abstract Ultrafiltration of skim cow’s milk with a UF10-PAN membrane at volume reduction ratios (VRRs) of 2 and 3 was performed. The ultrafiltration retentates obtained were used for production of probiotic yoghurts with three different starters. A control sample was prepared using skim cow’s milk. All yoghurts were analysed according to the following parameters: titratable acidity, dry matter, organoleptic

Sensory and ATP derivative-based indicators for assessing the freshness of Atlantic salmon (Salmo salar) and cod (Gadus morhua) Irish J. Agric. Food Res. (IF 1.5) Pub Date : 2019-10-31 Colin Fogarty, Conor Smyth, Paul Whyte, Nigel Brunton, Declan Bolton
Abstract To estimate the shelf life of fresh fish, the processor must know the period of time between catch/harvest and arrival at the processing plant. This information is not always available, necessitating the provision of methods to estimate the time since catch or harvest. The objectives of this study were therefore to develop and/or validate sensory and ATP derivative-based methods for rapidly

The agricultural impact of the 2015–2016 floods in Ireland as mapped through Sentinel 1 satellite imagery Irish J. Agric. Food Res. (IF 1.5) Pub Date : 2019-10-11 R. O’Hara, S. Green, T. McCarthy
Abstract The capability of Sentinel 1 C-band (5 cm wavelength) synthetic aperture radio detection and ranging (RADAR) (abbreviated as SAR) for flood mapping is demonstrated, and this approach is used to map the extent of the extensive floods that occurred throughout the Republic of Ireland in the winter of 2015–2016. Thirty-three Sentinel 1 images were used to map the area and duration of floods over

Prediction of 24-hour milk yield and composition in dairy cows from a single part-day yield and sample Irish J. Agric. Food Res. (IF 1.5) Pub Date : 2019-08-09 S. McParland, B. Coughlan, B. Enright, M. O’Keeffe, R. O’Connor, L. Feeney, D.P. Berry
Abstract The objective was to evaluate the accuracy of predicting 24-hour milk yield and composition from a single morning (AM) or evening (PM) milk weight and composition. A calibration dataset of 37,481 test-day records with both AM and PM yields and composition was used to generate the prediction equations; equations were validated using 4,644 test-day records. Prediction models were developed within

First evidence of retained sexual capacity and survival in the pyrethroid resistant Sitobion avenae (F.) (Hemiptera: Aphididae) SA3 super-clone following exposure to a pyrethroid at current field-rate Irish J. Agric. Food Res. (IF 1.5) Pub Date : 2019-04-17 L.E. Walsh, M.T. Gaffney, G.L. Malloch, S.P. Foster, M.S. Williamson, R. Mangan, G. Purvis
Abstract The grain aphid Sitobion avenae is a prolific pest of cereal crops worldwide, controlled effectively with pyrethroid insecticides. However, the classic knock down resistance (kdr) mutation, L1014F on the S. avenae sodium channel gene, has been identified as the cause of the recently observed heterozygous (kdr-SR) resistance in the SA3 grain aphid super-clone. Results indicate that the kdr-SR
