Abstract
U današnjoj proizvodnji mlijeka te sveukupnoj poljoprivrednoj proizvodnji nastoji se smanjiti uporaba antibiotika, pesticida, hormonskih pripravaka kao značajan iskorak prema održivijoj proizvodnji, a kasnije i prelasku na ekološki prihvatljiv način proizvodnje. Cilj ovoga rada bio je ispitati utjecaj upotrebe zeolita u cilju poboljšanja zdravlja krava, kroz smanjenje broja somatskih stanica kao glavnog pokazatelja zdravlja vimena, a shodno tomu i smanjenje pojavnosti mastitisa. Pokus ... More je proveden na 60 muznih krava podijeljenih u tri skupine prema broju laktacija. Prvu skupinu činile su krave u 1. laktaciji, drugu skupinu su činile krave 2. i 3. laktacije te su treću skupinu činile krave u 4. i višim laktacijama. Na početku pokusa prosjek dana u laktaciji svih krava je iznosio 160. Trajanje pokusa je bilo 42 dana te su provedene tri kontrole mlijeka (0., 21. i 42. dan), isto tako su istih dana provedena testiranja urina. Značajna razlika broja somatskih stanica u mlijeku nije zabilježena, iako je nominalno došlo do smanjenja broja somatskih stanica tijekom pokusa Značajna razlika u broju somatskih stanica je utvrđena između krava prve skupine u odnosu na krave druge i treće skupine. Nadalje, utvrđena je značajna razlika u postotku mliječne masti, koji je porastao tijekom pokusu. Za ostale parametre mlijeka nije utvrđena značajna razlika, izuzev koncentracije ureje za koju su zabilježene oscilacije između kontrolnih točki pokusa. Prema analizi urina utvrđeno je značajno smanjenje koncentracije proteina u urinu. Također, smanjena je pojavnost mastitisa među kravama u pokusu te se može zaključiti da iako nije zabilježeno statistički značajno smanjenje broja somatskih stanica, u praksi je premisa ovog pokusa uspješno potvrđena. Može se tvrditi da zeoliti kao dodaci u hranidbi krava imaju imuno stimulacijski, antibakterijski te antioksidacijski utjecaj na zdravlje vimena, a u konačnici i na opće zdravlje krava. Less
Abstract (english)
In today's milk production and overall agricultural production, the aim is to reduce the use of antibiotics, pesticides, hormonal preparations as a significant step towards more sustainable production, and later the transition to an environmentally friendly method of production. This experiment was set up in direction to examine the benefits of using zeolite in the direction of improving the health of cows, by reducing the number of somatic cells as the main indicator of udder health,... More and consequently reduce the incidence of mastitis. The experiment was performed on 60 dairy cows divided into three groups according to the number of lactations. The first group, consisted of cows in the 1st lactation, the second group consisted of cows in the 2nd and 3rd lactations, and the third group consisted of cows in the 4th and higher lactations, at the beginning of the experiment the average lactation day of all cows was 160. The duration of the experiment was 42 days and three milk controls were performed (0., 21st and 42nd day), also on the same days’ urine tests were performed. No significant difference according to statistical data processing regarding the number of somatic cells in milk was recorded, although nominally there was a decrease in the number of somatic cells according to the days in the experiment, a significant difference in the number of somatic cells was found between cows of the first group to cows of the second and third groups. Furthermore, a significant difference was found in the percentage of milk fat, which increased according to the days in the experiment. No significant difference was found for other milk parameters, except for concentration of urea for which oscillations were recorded between control periods. According to the analysis of urine, a significant reduction in the amount of excreted protein was found. Also, the incidence of mastitis among cows in the experiment was reduced and it can be concluded that although no statistically significant reduction in the number of somatic cells was recorded, in practice the premise of this experiment was successfully confirmed. It can be confirmed that zeolites as additives in the feeding of cows have immune stimulating, antibacterial and antioxidant effects on udder health, and ultimately on the general health of cows.
