“…In the present study the values of stearic acid in the buffalo milk are higher in comparison not only to the bovine milk but also to other results for the Bulgarian Murrah (Naydenova, 2005;Mihaylova and Peeva, 2007) and other breeds Varricchio et al, 2007). While in bovine milk worldwide the content of C18:0 varies in wide ranges (Samková et al, 2012;Beyero et al, 2015), on national scale the findings concerning mostly herds of Bulgarian Black and White cattle and other breeds are quite consistent (Mihaylova, 2007;Dimitrov, 2007), including our results. As we also found here, buffalo milk is considered to normally have lower levels of linoleic acid as compared to bovine milk elsewhere (Talpur, 2007;Ménard et al, 2010;Mihaiu et al, 2010), though for the Murrah breed Kumar and Kansal (2005) reported higher CLA levels.…”

“…Despites, system of feeding has been established to affect fatty acid (FA) profile of milk to certain extent (Dhiman et al, 1999;Fernandes et al, 2007;Beyero et al, 2015), although this is not attributed to the intake of functional FA's but to the different ruminal biohydrogenation and Δ9-desaturase activity (Shingfield et al, 2005;Kalač and Samková, 2010). This is relevant to the policy of the World Health Organization (FAO/WHO, 2003) to urge producers to improve the lipid profile of the foods of ruminant origin.…”

“…Ayaşan et al (2012-b) also found no difference between low, medium and high BCS groups for milk components except lactose and urea. Contrary to our findings, studies conducted by Beyero et al (2015) and Yi et al (2015) reported decrease in milk fat contents with the increased concentrate to roughage ratio, whereas, milk CP and SNF remained unaffected. Changes in milk solids and especially fats are associated with the degree of mobilization of fat reserves (Galic., 2017) in the early lactation and somatic cell count (Ayaşan et al 2011).…”

Improved feeding during pre-calving phase affects the Body Condition Score (BCS) that subsequently dictate the postcalving productive and reproductive performance. The objective of this study was to investigate the effect of three levels of concentrate supplementation [0.5, 1.0 and 1.5% of body weight (BW)] during pre-calving period on post-calving reproductive and lactation performance in Nili Ravi buffalo heifers. Twenty-six pregnant Nili-Ravi buffalo heifers at 150 ± 20 [Mean ± standard deviation (SD)] days in pregnancy with (BW=516± 57 KG, BCS (1-5) =3.98± 0.18) were selected and divided into three treatment groups; Low (n=8), Medium (n=9) and High (n=9) and allocated three dietary treatments. The treatments were basal diets composed of green fodder [dry matter (DM) = 2.0% of body weight (BW)] with three levels of Concentrates (CP=20.9 %, ME= 2.62 Mcal/kg) i.e. 0.5 (Low), 1.0 (Medium), and 1.5% (High) of the BW. The animals received same feed (forage DM at the rate of 2% of BW and concentrate at 0.5 kg per liter of milk produced on as fed basis) after calving. Increasing concentrate supplies from 0.5 to 1.5% of BW increased pre-calving dry matter intake (DMI), however, it didn't affect BW and BCS at calving. Increased concentrate supply at 1.5% of BW resulted in decrease in post calving conception rate to 33% as compared to 75 and 77.8% at 0.5 and 1.0% of BW concentrate supply. The treatment High decreased lactation length (15%) and yield (17%) as compared to Low and Medium treatment. Pre-calving supplementation of concentrate beyond 0.5% of BW showed no improvement of postcalving productive and reproductive performance. In the given dietary situation, the Nili Ravi heifers didn't require more than 0.5% of BW concentrate along with 2.0% of BW green fodder DM during post 150 days of pregnancy.

“…There are two possible reasons for this: firstly, the high levels of dietary concentrate supplementation of the stabled camels compared to the grazing camels. This is consistent with previous reports on dairy cattle, where increasing the concentrate to roughage ratio was observed to increase milk production substantially (Kuoppala et al 2004), DM and energy intake (Beyero et al 2015), and apparent digestibilities of DM, OM, CF, NDF and ADF fractions (Beyero et al 2015), while decreasing the growth of ruminal cellulolytic bacteria (Grant and Mertens, 1992) and milk fat percentage (Bauman et al 2008). The high level of concentrate in the diet gives rise to more propionic acid instead of acetic acid in the rumen, which in turn promotes partitioning of energy towards synthesis of body fat instead of milk fat, resulting ultimately in decreased milk fat (McDonald et al 2010).…”

“…However, during this period both groups were milked using this system, which directs attention back to the first reason. In fact, a number of earlier reports support the lack of effect observed in the present study on FCM production, as well as protein and lactose percentages with the high levels of dietary concentrate (Sutton, 1989;Beyero et al 2015). Furthermore, it was evident that the management applied herein had prominent effects on the MFA profile in dairy camels (Table 4).…”

The current research paper addresses the hypothesis that management system (grazing vs. stabling) and/or stage of lactation (early- to late-lactation) can influence the lactation performance and milk fatty acid (MFA) profile in dromedary camels. The results obtained revealed that milk and protein yields of stabled camels were higher, while milk fat content was lower compared to grazing camels. In addition, stabled camels produced milk richer in short- and medium-chains fatty acids but lower in long-chain fatty acids and fatty acids linked with possible health benefits such as oleic acid, vaccenic acid (VA) and rumenic acid (RA), when compared to grazing camels. Moreover, atherogenicity index was higher, while overall Δ9-desaturase and health-promoting indices were lower in stabled camels. In a similar way, results demonstrated an increase in milk fat and protein contents as lactation advanced. In fact, camels at mid-lactation produced milk richer in short- and medium-chain fatty acids as well as total saturated fatty acids but poorer in oleic acid, VA, RA, long-chain fatty acids and total unsaturated fatty acids, when compared to milk samples collected at early stage of lactation. Moreover, compared to early- and late-lactations, atherogenicity index was higher while overall-Δ9-desaturase and health promoting indexes were lower at mid-lactation. In conclusion, the intensive stabling system and mid-lactation stage can alter lactation performance and MFA profile in dairy dromedary camels.
