Data

The data describes the process and the management of the information for the study that compares the milk production and the production costs of a liter of milk of 33 dairy cows of two breeds: Brown Swiss and Jersey, fed with Maralfalfa (Pennisetun Sp) pastures. , Cameroon (Pennisetum purpureum) and Mulatto (Ciat 36087). The productive and reproductive biological variables with an impact on milk production are analyzed, including the most important days open, age at first calving, number of calvings and live weight. The basic selection criteria of the breeders for our study was that they had less than 60 open days; Selected cows should be in peak lactation. The milk production of the cows under study fed only with grazing Mulato was evaluated for 30 days, to generate a productive record and to have a productive history of these. After 30 days of monitoring milk production, the group of 33 cows was randomly divided into 3 groups, 11 cows per group, and they were assigned the type of grass to consume, establishing the Maralfalfa consumption group (G1). the consumer group from Cameroon (G2) and the control group with grazing mulatto (G3). A record of daily milk production of each cow was kept for 6 uninterrupted weeks, they were given equal management, in the same environment and with ad libitum feeding to the 3 groups under study with the only difference being the type of grass to be consumed. . When comparing the milk production of the groups of cows under study using the 1-Factor Anova statistical program, we found very significant statistical differences (p < 0.01) between the three groups studied from week 2 onwards. The most marked difference was presented by the G1 vs. G3 group. According to our results, the grass with the best productive efficiency for milk production is the Maralfalfa grass, since the group that consumed this grass was the one that presented the greatest increases in production volumes. However, when comparing the production costs of a liter of milk, we find that the highest cost is for maralfalfa and the lowest for mulatto and therefore the cost-benefit ratio is in favor of mulatto followed by Cameroon and maralfalfa respectively.
