Estudio de la calidad de leche de la Cabra Chusca Lojana en la zona de Gonzanamá y Calvas de la provincia de Loja

This research was carried out in the Santa Cruz area of the Gonzanamá canton and Bella María of the Calvas canton of the Province of Loja, with the purpose of determining the quality and the productive levels of milk according to the place, number of births, lactation stage and biotype; milk samples were taken from the “Chusca Lojana” goat, to 50 goats that were in different stages of lactation and number of births; Four visits were made with the purpose to coincide with the beginning, intermediate and end of breastfeeding with an interval of 15 days between visits. To determine the productive levels, the observational units were milked thoroughly in the early hours of the morning, with the help of a balance, the weight was taken, and a 50 ml sample of milk was collected to take to the laboratory and determine the quality. It was determined that the lactation stage of the “Chusca” goat lasts 180 days, reaching 51,360 ml, with a daily average of 285 ml ; presenting a peak of production around the first 30 days of the lactation stage with (586 ml), as well as the short and folded ear biotype (OCD) has the highest production (414 ml). The average of the following components was determined by chemical physical analysis: Fat (5,70%); Non-fatty solids (8,19%); Total solids (13,95%); Density (1,027g / ml); Lactose (4,50%); Mineral salts (0,67%); Protein (3,0%); Conductivity (5,09 mS / cm) and pH (6,84). It was determined that the milk of the Santa Cruz sector presented a better production and quality of milk compared to the Bella María sector. The Lion ear biotype (ODL), presented a better-quality milk compared to the other two biotypes analyzed. Determining that the quality of the milk in the present study is affected by the place in the majority of the components analyzed. Keywords: “Chusca lojana” goat, lactation duration, milk quality, parameters, biotype.
