The effect of L-carnitine supplementation during gestation and lactation on the performance parameters of sows was studied. The trial comprised a total of 73 sows that were divided into the control and treated groups; each was fed diets with and without supplemental L-carnitine during pregnancy (0 vs. 125 mg L-carnitine daily/sow) and lactation (0 vs. 250 mg L-carnitine daily/sow). L-carnitine supplementation resulted in the numerical increase of sow body weight at weaning (215.2±5.4 vs. 205.0±5.0, LSM±Se, p≥0.05), with a significantly expressed effect on sows born in 1998 (227.1±8.4 vs. 193.6±9.2, LSM±Se, p=0.01). There was a numerical increase in average number of total born and viable piglets per litter in treated sows (11.0±2.0 vs. 10.7±1.9, LSM±Se, p≥0.05; 10.8±2.1 vs. 10.4±1.9, LSM±Se, p≥0.05 respectively), although the tendency towards increasing the same parameters was determined in sows born in 1998 (11.00±0.54 vs. 9.82±0.59, LSM±Se, p=0.14; 10.9±0.6 vs. 9.5±0.6, LSM±Se, p=0.09). The total number of piglets which were smaller than 800g at birth tended to be lower (0.9±1.2 vs. 1.4±1.6, LSM±Se, p=0.08) and significantly different in sows born in 1998 (0.9±0.4 vs. 2.5±0.4, LSM±Se, p=0.01). The number of piglets fit for rearing was influenced by L-carnitine supplementation only in the sows born in 1998 (10.8±0.5 vs. 9.1±0.6, LSM±Se, p=0.03). The litter weight was not influenced by L-carnitine supplementation.

The aim of this research was to determine the effects of enzyme preparations, lysozyme and lysosubtilin in particular, and those supplemented with vitamins A, C and E, added to cows’ feed, on the somatic cell count and technological properties of milk which are considered primary important in cheesemaking. Three groups of Lithuanian Black and White cows (10 cows each) were fed on a ration supplemented with Neosomatas 1 preparation containing lysosubtilin, 0.02 g and lysozyme, 0.2 g, and Neosomatas 4 preparation (lysozyme, 0.2 g and vitamins A, C and E). The duration of the trial was 10 days. Measurements were conducted on the 4th, 7th and 10th day of the trial and 7 days following the trial. The reduction of somatic cell count in milk was observed during and after the feeding period. The highest effect of the feed supplement was observed in the third group which was fed on Neosomatas 4. The enzyme- and vitamin-based feed supplements were also effective with regard to the technological properties of milk. Changes in the acidity of milk during storage were rather slow. Likewise, the process of milk fermentation was slow, the properties of structures that were formed differed compared with control group of cows. However, the technological properties of milk from cows fed on Neosomatas 4 supplement were better as compared with cows fed on Neosomatas 1 feed supplement. Studies on the enzyme structure formation and the process of syneresis showed that feed supplements enriched with enzymes and vitamins had no effect on the above indices. It was also found that milk under study was characterised by good technological characteristics and therefore was suitable for cheesemaking.

A descriptive epidemiology and time series data analysis was used for the investigation of the development of the epidemiological situation related to enzootic rabies in Lithuania during the period of 1994-2004. A significant correlation between sample submissions and recorded rabies cases were detected (P<0.05). Since 1998, cases of wildlife rabies have been prevalent in all regions of Lithuania. Foxes and raccoon dogs were the main resource of this disease. Two seasonal peaks of wild animal rabies in spring and autumn were observed. Domestic animal rabies had only one seasonal peak in autumn. On the average, the prevalence of rabies increased from 23.5% in 1994 to 35.4% in 2004 in foxes and from 11.8% in 1994 to 28.9% in 2004 in raccoon dogs. The prevalence of rabies in cattle decreased from 25% in 1994 to 11.8% in 2004, in dogs from 19.1% in 1994 to 7.2% in 2004 and in cats from 17.6% in 1994 to 6.3% in 2004. 90.7% of all diagnosed rabies cases were diagnosed in foxes, raccoon dogs, cattle, dogs and cats. In 2004 the prevalence of rabies tended to decrease significantly in wild and domestic animals. A significant correlation was discovered between the prevalence of fox and raccoon dog rabies and the prevalence of wild animal rabies and dog rabies (P<0.05).

The purpose of the study was to determine the effect of a silage additive on maize silage fermentation and assess the relationship of silages with different levels of fermentation end-products to ruminal fermentation parameters and organic matter (OM) digestibility. The maize silage underwent two treatments: a) no additive (control silage), b) additive with Lactobacillus plantarum and Pediococcus acidilacticci and enzyme cellulase. The additive improved silage fermentative processes, preserved more water soluble carbohydrates, increased fermentation of lactic acid and decreased formation of ammonia-N. Two groups of analogous cows were formed: the cows (n = 10) of the control group were fed silage without additives, the cows (n = 10) of the experimental group the silage additive. Rumen fluid from cows was sampled. The silage additive improved fermentation processes in the rumen: the amount of volatile fatty acids, including propionic acid, increased as well as the total and lactate fermenting bacterial count and number of protozoa. The incubation of both grass hay and also silage with the rumen fluid from the cows receiving silage with inoculant and cellulase additive improved their OM digestibility.

The aim of this study was to analyze an effect of udder health status, somatic cell count (SCC), stage and number of lactations, and different seasons on the concentration of lactoferrin (LF) and immunoglobulin G (IgG) in quarter milk samples (n=120) from crossbreed (Lithuanian Black-and-White & Holstein) dairy cows. Quarter health status was based on SCC and microbiological analysis. The highest mean value of LF and IgG were observed in quarters with subclinical mastitis 0.1 ± 0.02 mg/ml and 0.41 ± 0.06 mg/ml, respectively. Grouping the data according to SCC revealed increased LF (0.07 ± 0.01 mg/ml as against 0.06 ± 0.01 mg/ml) and IgG values (0.27 ± 0.05 mg/ml as against 0.23 ± 0.02 mg/ml) in DQ (SCC from 201,000 ≥ 401,000 cells/ml) compared to HQ (SCC up to 200,000 cells/ml). The milk LF and IgG levels were effected by stage of lactation (p<0.01 and p<0.05, respectively) and season of the year (p<0.001 and p<0.001, respectively). Nevertheless, SCC and subsequent lactation (p>0.05) had no effect on these immunity components.
