“…The average DMY in our study was similar to those reported in the same breed (Fernandez et al 1995), and in the Comisana (Sebi et al 2000), and Chios breeds (Ploumi et al 1998), but was higher than were those reported in the Manchega and East Friesian breeds (Angeles-Hernandez et al 2017) and crossed ewes (Mioč et al 2009;Robles Jimenez et al 2020;Angeles-Hernandez et al 2018). Milk yields in Churra ewes were lower than were those in specialized dairy breeds such as Awassi, Lacaune, and Assaf (Elvira et al 2013;Gootwine and Goot 1994;Gootwine and Pollot 2000), and the differences are mainly because of genetic factors.…”

“…The dairy breed of the male or the genetic improvement program that is chosen will basically depend on three aspects: forage potential, adaptation of the dairy breed that is being introduced to the area, and the reproductive and productive characteristics of each one [8]. Within the dairy production and ovine cheese industry, a highlight is the initiative developed by the University of Magallanes in the city of Puerto Natales (Chilean Patagonia) that produces the southernmost cheese of Chile [9].…”

The constant increase in the demand for dairy products and their derivatives has generated a higher consumption of dairy products (113.5 t/year). Chile has not been the exception; in 2017, it presented an average per capita consumption of 11.1 kg of cheese, making it the largest consumer in Latin America, followed by Argentina (7.5 kg) and Uruguay (5 kg). Although Chile does not have a strong tradition of consuming sheep's milk cheese compared with other (European) countries, in recent years, there have been changes in the demands and expectations of cheese consumers, who demand higher quality and a wider range of varieties, thus establishing the potential for further products to enter the market. The global cheese industry has taken charge of these trends through the phenomenon of granting a premium value to certain products, adding new ingredients and flavors, producing limited editions of certain products, favoring traditional recipes and craft methods, and highlighting specific localities of origin. Given a greater appreciation for and popularity of locally produced cheeses and value-added products, particularly those with the highly valued "Designation of Origin" label, this would offer a potential for expansion in the Chilean market.

“…The analysis of dairy sheep production using mathematical models allows identifying the lactation curve's characteristics to develop and implement strategies (Angeles-Hernandez et al, 2018). However, the ability to represent the lactation process varies among mathematical models mainly due to its mathematical structure.…”

The ability of mathematical models to represent the lactation process varies according with their mathematical structure and database characteristics. The aim of the current study was evaluated the goodness of fit of empirical and mechanistic models applied to dairy sheep lactation curves with different shapes. A total of 4,494 weekly test day records were analyzed. All lactations were individually fitted using two empirical (Wood and Wilmink) and two mechanistic (Dijkstra, and Pollott) models. The Dijkstra model showed the best performance to typical curves and Wood model to atypical curves (without peak lactation). Therefore, the selection of the mathematical model to fit sheep lactation curves must consider the specific patter of milk production.
