Publikováno v: Journal of Dairy Science. 94:716-726

We constructed a regression model to estimate the retention of electronic boluses in goats. With this aim, 2,482 boluses were administered to goats from dairy (Murciano-Granadina, n=1,326; French Alpine, n=381) and meat (Blanca de Rasquera, n=532) br

Publikováno v: Journal of Dairy Science. 91:1438-1442

A total of 24 Murciano-Granadina dairy goats in early-midlactation were used to compare the labor time and data collection efficiency of using manual (M) vs. semiautomated (SA) systems for milk recording. Goats were milked once daily in a 2 x 12 para

Publikováno v: Journal of Animal Science. 84:2865-2872

Twelve types of electronic identification ruminal boluses of different dimensions were used to obtain a model for predicting their retention in the forestomachs of sheep. Boluses (n = 1,662) were made of ceramic materials, and their dimensions varied

Autor: D. Babot, Gerardo Caja, Clara Santamarina, J. J. Ghirardi, Marta Hernandez-Jover

Publikováno v: Journal of Animal Science. 84:2575-2581

A total of 1,822 pigs from 2 farms (farm A, n = 1,032; farm B, n = 790) were used to evaluate pig traceability under on-farm conditions by using identification devices (n = 4,434) of different technologies. The devices were visual ear tags (n = 1,533

Autor: Gerardo Caja, M.J. Milán, C. Saa, J. J. Ghirardi

Publikováno v: Journal of Animal Science. 83:1215-1225

A cost model was developed to compare different implementation strategies of the new European Commission regulation for sheep and goat identification and registration (EC 21/2004) in Spain. Strategies were as follows: 1) conventional identification (
