“…This study obtained results which were not in agreement with the findings of a great deal of the previous research (Dhakal et al,1992;Singh and Ludri, 2001), which determined that the SCC recorded for buffaloes varied from 50,000 to 375,000 cell/ml. It was notified that the somatic cell average value of Mediterranean buffaloes is 169,000 cells/ml (Esposito et al,1997); in another study on water buffaloes, the SCC value was reported as 309,000/ ml (Tantillo et al, 1997).…”

The present research was conducted to determine the effects of parity, calving season and stage of lactation on the somatic cell count (SCC) in Anatolian water buffaloes reared different herd conditions. In total, 2,736 SCC readings from 456 Anatolian water buffaloes were analyzed. Data were evaluated by the stage of lactation (early, mid, and late), calving season, and parity with the SPSS package program. Significant effects of calving season, parity, and stage of lactation on SCC were observed (P<0.05). The average SCC was 90,701±6,372 cells/ml. The results indicated that the SCC of buffaloes were in accordance with, even considerably lower than, the limits indicated in the related regulations of the Turkish Food Codex and those of the European Union Commission. Further studies are necessary to investigate the development of the appropriate threshold values under the conditions of Turkey.

“…aureus can cause damage to the developing secretory tissue that can lead to decreased milk yield followed by increased SCC. Somatic cell count is usually used as indicator of inflammation to diagnose mastitis (Dhakal et al, 1992;Singh and Ludri, 2001;Moroni et al, 2006), and, according to Cerón-Muñoz et al (2002), elevated SCC values were related to reduced lactose concentration and milk yield. According to several studies in buffaloes, quarters producing milk with an SCC below the threshold of 200 × 10 3 cells/mL and associated with negative bacteriological cultures (BC) are considered healthy; quarters with analogous SCC values and positive BC caused by udder-specific pathogens are considered affected by IMI.…”

Staphylococcus aureus is one of the most important pathogens causing mastitis in dairy cows and in Mediterranean buffaloes. Genotype B (GTB) is contagious in dairy cows and may occur in up to 87% of cows of a dairy herd. It was the aim of this study to evaluate genotypes present, clinical outcomes, and prevalence of Staph. aureus in milk samples of primiparous Mediterranean dairy buffaloes. Two hundred composite milk samples originating from 40 primiparous buffaloes were collected from May to June 2012, at d 10, 30, 60, 90, and 150 d in milk (DIM) to perform somatic cell counts and bacteriological cultures. Daily milk yields were recorded. Before parturition until 40 to 50 DIM, all primiparous animals were housed separated from the pluriparous animals. Milking was performed in the same milking parlor, but the primiparous animals were milked first. After 50 DIM, the primiparous were mixed with the pluriparous animals, including the milking procedure. Individual quarter samples were collected from each animal, and aliquots of 1 mL were mixed and used for molecular identification and genotyping of Staph. aureus. The identification of Staph. aureus was performed verifying the presence of nuc gene by nuc gene PCR. All the nuc-positive isolates were subjected to genotype analysis by means of PCR amplification of the 16S-23S rRNA intergenic spacer region and analyzed by a miniaturized electrophoresis system. Of all 200 composite samples, 41 (20.5%) were positive for Staph. aureus, and no genotype other than GTB was identified. The prevalence of samples positive for Staph. aureus was 0% at 10 DIM and increased to a maximum of 22/40 (55%) at 90 DIM. During the period of interest, 14 buffaloes tested positive for Staph. aureus once, 6 were positive twice, and 5 were positive 3 times, whereas 15 animals were negative at every sampling. At 90 and 150 DIM, 7 (17.5%) and 3 buffaloes (7.5%), respectively, showed clinical mastitis (CM), and only 1 (2.5%) showed CM at both samplings. At 60, 90, and 150 DIM, 1 buffalo was found with subclinical mastitis at each sampling. At 30, 60, 90, and 150 DIM, 2.5 (1/40), 22.5 (9/40), 35 (14/40), and 10% (4/40) were considered affected by intramammary infection, respectively. Buffaloes with CM caused by Staph. aureus had statistically significantly higher mean somatic cell count values (6.06 ± 0.29, Log 10 cells/mL ± standard deviation) and statistically significantly lower mean daily milk yields (7.15 ± 1.49, liters/animal per day) than healthy animals (4.69 ± 0.23 and 13.87 ± 2.64, respectively), buffaloes with IMI (4.82 ± 0.23 and 11.16 ± 1.80, respectively), or with subclinical mastitis (5.47 ± 0.10 and 10.33 ± 0.68, respectively). Based on our knowledge, this is the first time that Staph. aureus GTB has been identified in milk samples of dairy Mediterranean buffaloes.

“…Pooled milk samples were analyzed for fat (Indian Standard Institution, ISI, 1958), protein (AOAC, 1990), total solids, solids-not-fat using standard procedures immediately after collection. Somatic cell counts (SCC) in fresh milk samples were measured (Singh and Ludri, 2001). …”

Twenty crossbred lactating multiparous cows were used in a 28-day study to compare dry matter intake (DMI), milk yield, milk composition and Bacillus thuringiensis (Bt) protein concentrations in plasma when fed diets containing Bollgard II R cottonseed (BGII) or a control non-genetically modified isogenic cottonseed (CON). Bollgard II cottonseed contains the Cry1Ac and Cry2Ab insecticidal proteins that protect cotton plants from feeding damage caused by certain lepidopteran insects. Cows were assigned randomly to the BGII or CON treatments after a 2-week adjustment period. Cows consumed a concentrate containing 40% crushed cottonseed according to milk yield and green maize forage ad libitum. All cows received the same diet but with different crushed cottonseed sources. Cottonseed was included to provide approximately 2.9 kg per cow daily (dry matter basis). The ingredient composition of the concentrate was 40% crushed cottonseed, 15% groundnut cake, 20% corn, 22% wheat bran, 1% salt and 2% mineral mixture. Milk and blood plasma were analyzed for Cry1Ac and Cry2Ab proteins. DMI, BW, milk yield and milk components did not differ between cows on the BGII and CON treatments. Although milk yield and milk fat percentage were not affected by treatment, 4% fat-corrected milk (FCM) production and FCM/kg DMI for cows on the BGII treatment (14.0 kg/cow per day, 1.12 kg/kg) were significantly improved compared with cows on the CON treatment (12.1 kg/cow per day, 0.97 kg/kg). Gossypol contents in BGII cottonseed and conventional cottonseed were similar. Cry1Ac and Cry2Ab2 proteins in Bollgard II cottonseed were 5.53 and 150.8 mg/g, respectively, and were not detected in the milk or plasma samples. The findings suggested that Bollgard II cottonseed can replace conventional cottonseed in dairy cattle diets with no adverse effects on performance and milk composition.
