The effect of feed push-up has already been proven in several studies, so this topic can be considered one of the main points that helps improve the health status of dairy cattle. This study aimed to determine how the frequency of feed push-ups influences the health status of udder (mastitis), somatic cell counts, and reproduction. The effect of feed push-up on mastitis, the somatic cell counts, and the conception of dairy cows was evaluated. The feed was pushed-up at a frequency of 2x, 3x, 4x, 5x, and 6x a day for one calendar month. The effect on the number of dairy cows treated with mastitis was insignificant (P ≥ 0.05). The lowest number of cows with mastitis was found when feed was pushed-up five times daily. The effect on the somatic cell counts was insignificantly, too (P ≥ 0.05). The worst milk quality was found in the experimental group, which had a frequency of push-up 5x/day. However, it has been shown that the frequency of food push-up positively affected the conception rate in dairy cows (P < 0.001).

This study evaluated the effect of different feed pushing-up frequencies on the behavior, dry matter intake and milk production of dairy cows in the first lactation. In each monitoring, 32 - 37 dairy cows of Czech spotted cattle at the peak of lactation were represented. After the feed was delivered to cows, the feed was pushed-up 2, 3, 4, 5, or 6 times in 5 different frequencies within 12 hours. Each frequency was monitored for 1 month in four repetitions. The behavior of dairy cows during feeding was monitored for 15 minutes after the feed delivery and after each food pushing-up. We evaluated how often the dairy cows came to the feeding table, how they used mixed ration and milk production. The frequency of feed pushing-ups has shown an effect on the dairy cow's milk yield. As a result of the 2, 3, 4, 5 and 6 feed pushing-up frequencies, the average milk production per cow per day was 24.52; 25.84; 25.48; 25.78; 26.03 kg. Also feed conversion increased with the frequency of feed pushing-ups to 1.22; 1.29; 1.25; 1.30 aand nd 1.30 kg of milk from 1 kg of received dry matter. TMR dry matter utilization increased by 1% on average.

The aim of the first experiment was to verify the effectiveness and profitability of providing supplemental feed to piglets. The milk feed mixture of two producers (MFM-1 vs MFM-2) were evaluated (served ad libitum). All piglets were suckled and were fed with the pre-starter feed mixture from the 5th day until the weaning stage. The control group without milk supplements has shown a higher piglet mortality and worse body condition of sows. The usage of milk supplements led to the elimination of the sow body condition loss during the suckling period and reduced feed mixture consumption in sows (P

The target of the research was to analyze the effect of antidiarrheal feed additives on calves average daily weight gain. In the study, 120 calves were analyzed. Newborns were selected into 3 treatment groups, control (without supplementation) and group with Ascophyllum nodosum (prebiotics), and mixture of Lactobacillus sporogenes, Enterococcus faecalis and Bifidobacterium bifidum (probiotics). Individual body weight of animal were determined after 2 hours post-partum. Monitoring of the growth intensity, as well as health status were done till 56 days of age. Significant effects (P

The aim of this study was to determine how the administration of probiotic feed supplements affects selected parameters rumen environment of cattle, how it impresses the basic chemical and biological processes in the rumen, and also to check their influence on the total digestibility of feed in the cannulated cattle. For the experiment two adult cows of Aberdeen Angus breed with implanted permanent cannula were used, whom probiotics Bifidobacterium sp. were administered daily and subsequently the degradability of the organic matter was determined by the in sacco method. From the samples of rumen fluid, the amount of ammonia, volatile fatty acids, ciliates and pH were analyzed. The impact of probiotics has not been demonstrated in testing the influence of probiotics on the different variables with fixed effect of an individual. When testing the influence of probiotics without the effect of an individual, in the linear model, obtained data of acetic and butyric acid were the best. In their dependence, numbers of protozoa were increasing. However, only two experiment individuals were tested, a strong effect of the individual was found. These results indicate that the effect of probiotics Bifidobacterium sp. on the functional state of the rumen is low.
