“…in Holstein cows supplemented with protected fat 10 g/lit milk (Gowda et al, 2013) indicates usefulness of pre-and post-partum feeding in eliciting higher milk production response than feeding alone in early lactation or post-partum. On the contrary, Veira et al (2001) reported decline in milk production of mid-lactating Holstein cows supplemented with 3% soybean oil which is in support with the present findings of reduction in milk yield from 5 th fortnight onwards. This may have been due to the depression in diet digestibility due to impaired rumen function caused by higher levels of oil intake (i.e.…”

The study determined the response of diet supplemented with mustard oil on production performance in lactating Murrah buffaloes at Livestock Farm, College of Veterinary Science and Animal Husbandry, NDVSU, Jabalpur, M.P., India. A total of 12 advance pregnant Murrah buffaloes were selected 21 days pre-partum and randomly allocated in 2 groups of 6 each: CON as control with basal diet + no oil and MO as treatment with basal diet + mustard oil supplementation 200 ml/animal/day. The trial was continued for 90 days post-partum. Significant positive response (%) in the daily milk yield, milk fat percent and 6% fat corrected milk yield by 8.10, 9.14 and 14.47, respectively was observed in MO in comparison to CON. Besides, there were insignificant findings for DMI, milk solid not fat, protein and lactose per cent, peak milk yield, persistency of lactation and predicted lactation yield (PLY) between the groups. The study affirms that supplementation of mustard oil improves the production potential of lactating Murrah buffaloes and could be recommended to dairy farmers during transition period and early lactation to earn profits.

The present study was conducted at Livestock farm, Adhartal, College of Veterinary Science & A.H., N.D.V.S.U., Jabalpur (M.P.). A total of 12 advance pregnant Murrah buffaloes of identical parity and similar previous lactation yield were selected 21 days prepartum and randomly assigned to two groups of six animals each; CON as control with basal diet and MO as mustard oil supplementation @ 200 ml/animal/day upto 90 days post-partum to study the effect on economics of milk production in lactating Murrah buffaloes. The daily milk yield was recorded individually twice at 6 A.M. and 4 P.M. and the milk fat per cent was studied using ultrasonic auto milk analyser. Results revealed reduced feed cost (Rs.) per kg 6% FCM yield in MO (19.03) than CON (20.25) and highest return of Rs. 270.82 per animal per day in MO. The net return in comparison to CON was Rs. 45.94 in MO which suggests that supplementation of MO is economically feasible. The additional benefits are due to significant (p<0.05) improvement in average daily milk yield by 8.10 per cent and milk fat content by 9.14 per cent in MO as compared to CON. The 6% FCM yield were significantly (p<0.05) higher in MO followed by CON. In conclusion, MO provided more economic returns to the dairy farm.

“…When feeding a high amount of soy equalling 30% of supplementary diet, a negative impact was found by Pereira et al (1998ab) of a decrease in the feed intake and fat content in milk. Veira et al (2001) describe a negative impact on fibre digestibility, milk yield, protein content and particularly substantial decrease in the fat content in milk when feeding soy oil at the amount of 3% of the total diet. This project is based on the results of an experiment which has proved a negative effect of a higher fat content (6.9% of dry matter) in the diet on the hepatic steatosis development (Lubojacká et al 2005;Pechová et al 2006).…”

Influence of Full-fat Soybean Seeds and Hydrolyzed Palm Oil on the Metabolism of Lactating Dairy Cows

The aim of the study was to compare the influence of fat supplementation in the form of full-fat soybean seeds and hydrolyzed palm oil as energy sources for dairy cows in early lactation.During the first 8 lactation weeks, 17 dairy cows divided into group S (n = 8) and group C (n = 9) were observed. The basic diet was the same for both groups. The differences were in the composition of the concentrate mixture, which had a balanced content of nutrients. In group S the fat source was heat-treated soybean seeds, while in group C the fat source used was hydrolyzed palm oil. The two diets started to be fed on the day of calving. Blood samples were taken weekly (1 st -5 th week) and 8 weeks after delivery. At the end of the experiment ruminal fluid was taken. During the experiment BCS in both groups deteriorated similarly. In group S it decreased from 3.8 ± 0.2 to 3.3 ± 0.3 and in group C from 3.5 ± 0.4 to 3.1 ± 0.4. A better performance of hepatic metabolism was proved in group S. In group S lower concentrations of non-esterified fatty acids were identified in the 3 rd (0.96 ± 0.38 vs. 1.76 ± 0.63 mmol·l ; p < 0.05) week after calving. The gamma-glutamyl transferase (EC 2.3.2.2) activity in serum indicates a better liver parenchyma condition in group S where no increased activity was identified above the reference range. An increased activity was identified in group C from the 2 nd week with a significant difference between groups detected in the 2 nd (0.41 ± 0.07 vs. 0.66 ± 0.25 µkat·l -1 ; p < 0.05) and 4 th (0.42 ± 0.05 vs. 0.64 ± 0.25 µkat·l -1 ; p < 0.05) weeks after delivery. There were no significant differences found between groups in bilirubin and aspartate transaminase (EC 2.6.1.1) but a general tendency toward lower values is apparent in group S. No significant differences were found between groups by the examination of ruminal fluid.Based on these results we can conclude that full-fat soy was better utilised than hydrolysed palm oil and represents a suitable alternative for increasing energy concentration in the diet for dairy cows. On the other hand, the development of liver steatosis in cows make controversial the usage of fat as an energy source for fresh cows even if their BCS is around 3.5-3.8 and it may not be recommended generally. Soy, liver, lipid mobilization, blood, BCS, isoenzymes LDHLack of energy is the main limiting factor to high yields of dairy cows. Taking into account the low intake of dry matter and the fast increase of milk production in dairy cows after calving, it is important to provide a high energy concentration in the diet during this period. One possibility of solving the energy deficit in dairy cows in this period is to use supplementary fats. The main reason for using fat is its 2-3 times higher energy content compared to saccharides or proteins. The source of fat for dairy cows should have a high content of pure energy, high digestibility, acceptable palatability and price and should be easily manipulated. Fat in the diet can come from different sources, such as natu...
