  The effect of Saccharomyces cerevisiae on milk yield, milk compositions and body condition score raised organically in dairy cows

  Bayram, Bahri; Aksakal, Vecihi; Karaalp, Musa; Mazlum, Halit

  The objective of this study was to evaluate the effect of Saccharomyces cerevisiae (SC) on milk yield, milk compositions and the body condition score raised organically in dairy cattle. For this aim, 120 lactating Holstein Friesian dairy cows were randomly divided into group control (n = 60) and treatment (n = 60) in a private organic dairy farming in the Kelkit District of the Gumushane Province in Turkey. The diet of group treatment each cow was supplementation with 6 g SC per day. The experimental was started after 30 days of calving and lasted 45 days after. The average daily milk yield production (p<0.01) was higher in the SC group (34.6±0.31 vs. 31.8±0.44kg day-1 in the treated and control group, respectively). The effect of SC on some milk compositions as non-fat solids (%), milk fat (%), protein (%) and lactose were statistically non-significant. Body condition score in the treated group (2.74±0.016) was higher than control group (2.58±0.017) (p<0.01). It was concluded that milk yield capacities in organic dairy cattle farming in case that the similar results are confirmed with additional studies can be substantially increased.

  EFFECT OF THE BODY CONDITION SCORE ON SOME REPRODUCTION AND MILK YIELD TRAITS OF SWEDISH RED AND WHITE COWS

  Bayram, B.; Aksakal, V.; Akbulut, O.

  This study examined the effect of body condition score (BCS) at calving and during the first month of lactation on some reproduction and milk yield traits of Swedish Red and White (SRW) cows organically raised in Turkey. For this purpose, SRW cows divided two groups, named as thin (BCS <3.00) and moderate (BCS >= 3.00). The actual milk yield (815 kg) and 305 day daily milk yield (736 kg) of cows with low condition score at calving were significantly (P<0.01) higher than those with moderate condition score. The BCS at calving did not have an effect on the lactation length, peak daily milk yield and days to attain peak milk yield. The condition score obtained in the first month of lactation only affected the peak daily milk yield (P<0.05), while its impact on the other characteristics was non-significant. The service period of the cows with low condition score at calving was significantly longer (19.9 day) and their number of services per conception was significantly lower (0.37 units) (P<0.05) than moderate group. The condition loss was calculated as 0.0137 units in the thin group and 0.2290 units in the moderate group and this differences were significant (P<0.01) during the first 30 day period of lactation. The phenotypic correlation between BCS at calving and milk yield traits were negative and significant (P<0.01). According to this relationship, actual milk yield (r=-0.208), 305 day milk yield (r=-0.248) and peak daily milk yield (r=-0.251) decreased significantly (P<0.01) with the increase in the BCS at calving. The service periods of cows with low condition scores at calving were significantly longer (P<0.01).
