Genetic parameters for milk yield, fat and protein milk content and "mozzarella" index were estimated in the population of Romanian Buffalo from Sercaia Research and Development Station. A total 609 milk yield and associated characters records, belonging to 87 females, which coming from 11 sire families, for 7 lactations were analyzed. The method used for genetic parameters estimates was REML. There was a large variability in all analyzed traits. Estimated heritability was small to medium for al examined traits. The milk yield is negatively correlated with fat and protein content, and weak positive with "mozzarella" index. Fat and protein milk content are high positive correlated with mozzarella production. In the long term, the female selection for milk yield will be (make) to the detriment of quality. Genetic improvement of the quantity of mozzarella will be make only on account of milk constituents that impart its quality. According to heritability values, in the process of female genetic evaluation appears advisable to use additional information sources in order to increase the accuracy of selection.

Farming livestock—cattle, sheep, goats, pigs, and chickens—contributes to the air pollution of the atmosphere. Agricultural air pollution comes mainly in the form of ammonia, which enters the air as a gas from heavily fertilized fields and livestock waste. A reduction in air pollutants from the livestock sector can be achieved by reducing production and consumption, lowering the emission intensity of production, or combining the two. This work proposes an approach for assessing the air pollutant emissions derived from intensive cattle farming. For doing this, the animal feed, the animal behavior, and characteristics and the stable environment data are monitored and collected by a cloud platform. Specifically, Internet of Things (IoT) devices are installed in the farm and key air pollutant parameters from the stable environment (such as CO, NH3, PM1, PM2.5, PM10) are monitored. In this scope, a study about monitoring air pollutants is conducted, showing the most relevant platforms used in this domain. Additionally, the paper presents a comparison between the estimated and monitored air pollutants (AP), showing the fluctuation of the measured parameters. The key takeaway of the study is that ammonia concentration has a higher level during the night, being influenced by the ventilation system of the farm.
