This paper focuses on the role of n-3 fatty acids as a nutrient crucial to the proper functioning of reproductive and immune systems in cattle. Emphasis was placed on the connection between maternal and offspring immunity. The summarized results confirm the importance and beneficial effect of n-3 family fatty acids on ruminant organisms. Meanwhile, dietary n-3 fatty acids supplementation, especially during the critical first week for dairy cows experiencing their peripartum period, in general, is expected to enhance reproductive performance, and the impact of its supplementation appears to be dependent on body condition scores of cows during the drying period, the severity of the negative energy balance, and the amount of fat in the basic feed ration. An unbalanced, insufficient, or excessive fatty acid supplementation of cows’ diets in the early stages of pregnancy (during fetus development) may affect both the metabolic and nutritional programming of the offspring. The presence of the polyunsaturated fatty acids of the n-3 family in the calves’ ration affects not only the performance of calves but also the immune response, antioxidant status, and overall metabolism of the future adult cow.

The present study was carried out to investigate the effects of lactic acid bacteria inoculant on quality, fermentation profile and nutritive value of alfalfa silage at different fermentation periods. After harvesting, fresh alfalfa samples were packed into polyethylene film and the commercial lactic acid bacteria inoculant was used as silage additive. Totally of 21 silage packages were opened by weekly for the analysis. Smell, color, structure, and total scores of alflalfa silage were significantly increased from the first week. Silage quality was determined medium at 7th day; good between 14th and 42th days; excellent at 49th day. The Flieg point was gradually increased after d 28 of ensiling (P<0.05). While pH was reduced at 5.15; NH3-N/TN content of alfalfa silage was increased at 15.70% at the end of the study. We observed an increase in acetate concentration and decrease in propionate and butyrate concentrations in the alfalfa silage. Lactate concentration was significantly increased on day 35 of the fermentation (P<0.05). Crude fiber (CF), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF) contents of alfalfa silage were decreased, whereas nitrojen free extract (NFE) and non-fiber carbohydrate (NFC) were increased during ensiling period. According to our findings, fermentation period had a significant effect on digestible dry matter, dry matter intake and relative feed value of alfafa silage (P<0.05).

The aim of this study was to evaluate the effects of probiotic on ruminal pH, ammonia nitrogen, production of short chain fatty acids (SCFA) and number of Ruminococcus albus and Ruminococcus flavefaciens. The probiotics blend was tested in vitro for 48 h incubation using “Hohenheim Formation Test” (HFT). There was no interaction effect of the treatment and incubation time on the ruminal pH and ammonia-nitrogen concentration. A supplemental probiotics blend tended to increase the total SCFA concentration in comparison to the non-supplemented control fermenter fluids (P> 0.05). There was a significant interaction effect of the treatment groups and incubation time on butyrate (P=0.042), valerate (P=0.045) and isovalerate (P= 0.028) concentrations. Total protozoa and total bacteria numbers were higher in probiotics supplemented fluid than in non-supplemented control fluid (P 0.05) the number of copies of R. albus. However, population of R. flavafaciens was lower (P<0.01) in the probiotic supplemented group as compared with the non-supplemented control group. Our results showed that the probiotics blend might modulate both microbial metabolic activity and population of ruminal microorganisms.

DOI : 10.26650/actavet.2019.18010 The effect of Mediterranean mussel shell (Mytilus galloprovincialis) (MMS) on performance, egg quality and some blood parameters were studied on quails (Coturnix coturnix Japonica) for a period of 10 weeks (13-23 weeks). A total of 90 quails were randomly separated into one control and two treatment groups. Each group was divided into six subgroups, each containing 5 animals. MMS was replaced with lime stone at the ratios of 50 and 100% in first (50% MMS) and second (100% MMS) group rations respectively. The diets were prepared to be isocaloric and isonitrogenous. Rations and water were given ad libitum. Ca source replacement did not significantly affect body weight, egg weight, egg yield, feed intake and feed conversion ratio of laying quails. The effects of MMS replacement on shape index, yolk index, yolk color, blood Ca, Mg, P levels with Mg and P levels of egg shell had no significance. Ca levels of egg shell decreased (p<0.05) in treatment groups however, the amount of crude ash of tibia was not altered. In sum, dietary MMS did not alter egg quality of laying quails. It may be concluded that MMS can be replaced with limestone in the diet of laying quails.

ABSTRACT The objective of this study was to investigate the effects of sumac and turmeric on performance, egg quality traits, and blood parameters of laying hens. Forty Lohman Brown hens at 30 weeks of age were distributed into four groups, consisting of five replicates with two hens in each. The experiment lasted for 42 days. Laying hens were fed different basal diets in treatment groups and control groups. The groups consisted of hens fed a basal diet with 0.5% sumac, [...]

ABSTRACT The influence of different levels of expanded perlite on the performance and egg quality traits was studied in laying hens. Forty Lohmann Brown females at 30 weeks of age were randomly assigned to four groups consisting of five replicates with two hens in each. Four diet groups were supplemented with 0% (control group), 1%, 2%, and 3% perlite, respectively. Feed and water were provided ad libitum. There were no significant differences in final body weight, feed intake, egg yield, [...]

The aim of this study was to investigate the effects of live yeast culture and the live yeast culture enriched with vitamin-mineral supplementation as a feed additive on fattening performance, some blood and rumen fluid parameters in male kids. Totally 18 male Saanen goat kids (average 8 weeks old) were divided into one control and two treatment groups each containing 6 kids. Rations were prepared as isonitrojenic and isocaloric. Live yeast culture (LYC) and the yeast-vitamin-mineral complex (YVM) (RumiSacc® and Intetotal® respectively, Integro food Industry and Trade Co., Istanbul, Turkey, Live yeast cell 344 x 1010 cfu/g,) were incorporated into concentrates at the level of 0% (C), 1% (YC) and 1% (YVM) on as-fed basis. During the study concentrate feed and fresh water were given ad libitum and the ration did not contain any roughages. Dietary yeast culture at the level of 1% increased final live weight (4.7% regarding control group) as numerically but not significantly. The fattening performance, rumen fluid and blood parameters were not statistically affected from the dietary treatments throughout the study. While the dorsal papillae length was not changed, ventral papillae length was decreased in the treatment groups. The length of papillae in YVM groups were similar to that of control groups.

This study was carried out to determine the effects of dietary inactive yeast and live yeast on performance, egg quality traits, some blood parameters and antibody production to sheep red blood cell (SRBC) of laying hens during 16 weeks. A total of 96 Hyline Brown laying hens were allocated into one control group and three treatment groups each containing 24 hens. Each group had six replicate groups of 4 hens. A basal diet was supplemented with 1 g/kg inactive yeast (yeast autolysate, InteWall, Saccharomyces cerevisiae), 0.5 g/kg live yeast (InteSacc, Saccharomyces cerevisiae) and 1 g/kg inactive yeast + 0.5 g/kg live yeast in the diets of the first, second and third treatment groups, respectively. At the end of the study the results indicated that dietary treatments did not affect feed intake, interior and exterior egg quality characteristics. Dietary inactive yeast supplementation improved hen-day egg production (P=0.024) and feed conversion ratio (P=0.017) and decreased egg yolk cholesterol concentration (P=0.013). Antibody titers against SRBC and blood serum parameters were not affected by dietary treatments. The significant interaction was found in egg yolk cholesterol concentration (P=0.032) between inactive yeast and live yeast. As a result dietary inactive yeast at the level of 1 g/kg had beneficial effects in laying performance and in low cholesterol-egg production.
