Effect of coffee pulp on milk quality in grazing goats in northern Mexico

Abstract

In this work, the effect of PCaf supplementation on productive parameters, production and milk quality in goats under grazing conditions was evaluated, so that producers have other supplementation options for their animals contemplating the best productive performance of goats.20 multiracial goats in milk production with an average production of 1.5 L of milk were divided into 2 groups (n=10 each) homogeneous in terms of live weight and body condition. A first group (Treated) was supplemented with 150 g of PCaf plus 150 g of commercial concentrate (17% PC, 1.5 ME) and 2% molasses of the total ration, while a second group (Control) received 100 g of commercial concentrate. The study period was 21 days. The supplementation of the animals was individual in the morning (8:00 am) during the entire experimental period. The following variables were evaluated: Live Weight (LW), Body Condition (BC), production and determination of milk quality, the data were analyzed with the t-Student test. The results in terms of LW, BC, milk production, protein content, lactose, non-fat solids and total solids showed no difference (P>0.05) for both groups, however, in the average fat content there was a significant difference, trend where higher values ​​(P<0.05) were found in the milk of the goats supplemented with PCaf (3.2%), in relation to that from the control group goats (2.9%). It is concluded that dietary supplementation with PCaf could be a viable alternative to improve milk quality, without decreasing milk production in multibreed goats under grazing conditions in northern Mexico
