Influence of fat supplementation on mare’s milk composition

Various fats are used in swine diets as sources of energy and essential fatty acids. Our aim was to evaluate the effects of fat supplementation during gestation on reproductive performance, milk composition of sows and intestinal development of their offspring. Fifty sows were randomly allocated into two groups receiving the control (CON) and high-fat diets (HF diet) during gestation. After farrowing, all sows received the same lactation diet and were fed ad libitum until weaning at day 20 of lactation. The results showed that being fed the HF diet did not markedly improve the performance of sows and their offspring. However, the HF diet increased (p < 0.05) the colostrum contents of protein and no-fat solids, and the plasma concentration of prolactin at farrowing. Moreover, piglets born of sows fed the HF diet had higher (p < 0.05) jejunal villous height, as well as deeper (p < 0.05) jejunal and colonic crypt depths compared with piglets born of sows fed the CON diet. In addition, piglets born of sows fed the HF diet had markedly increased (p < 0.05) mRNA abundances of innate immunity-related genes on toll-like receptor 4 (TLR-4), toll-like receptor 9 (TLR-9) and myeloid differentiation factor 88 (MyD88) in ileum compared with piglets born of sows fed the CON diet. These findings indicated that dietary fat supplementation during gestation did not markedly improve the performance of sows and their offspring, but improved colostrum quality and concentration of prolactin on the day of farrowing, associated with modifications of intestinal morphology and innate immunity of their offspring.

Bypass Fat

The present study was planned to cope with feed scarcity issue using bypass fat as a non-conventional feed resource. Twentyfour early lactating indigenous dairy animals comprising of twelve Nili-Ravi buffaloes and twelve Sahiwal cows were selected to determine the effect of bypass fat supplementation on daily milk yield, milk composition and change in body weight. These animals were randomly distributed in to four groups (G0, G1, G2 andG3) having similar parity and milk yield. All the experimental animals were fed with basal ration (Trifolium alexendrinum + wheat straw) and concentrate in equal proportion (3kg day-1 animal-1 ) in addition to 0, 250, 350 and 450g bypass fat animal-1day-1 , respectively. Data collected for each treatment was analyzed under completely randomized design using MINITAB (2000) and the mean was compared using the Tukey’s test (P<0.05). The data revealed a significant effect (P<0.05) on milk production and 3.14 kg day-1 more milk was produced in group G2 compared to control group. Fat corrected milk yield was also enhanced (P<0.05) from 8.25 (G0) to 12.36 kg day-1 (G2). Milk composition in the sense of fat percentage was also improved [5.25 (G0) to 5.78 (G2)] significantly. While average protein content, SNF% and total solids% remained unaffected. Similarly, change in body weight was non-significant. Milk value (Rs./day) was significantly (P<0.05) increased from 512.25 to 747.75 in the group G0 to G2. Form present finding it could be concluded that dietary supplementation of bypass fat in indigenous dairy animals is a better option to increase the milk yield without compromising milk quality and animal health

Effect Of Feeding

The study was conducted to evaluate the effect of feeding herbal galactogogue preparation (Sanjivani biokseera) on the milk yield and milk constituents in lactating Kankrej cows. Thirty-two lactating Kankrej cows in their 1st to 6th lactation were taken for the experiment from 3 days after calving up to 52 days postpartum. All the animals were fed as per the standard seasonally available roughages and concentrates to meet their nutritional requirements. The cows were randomly divided into two uniform groups of 16 cows in each according to initial milk yield and milk composition. The animals in group-I were not given any supplement and served as control. The animals in group-II were given Sanjivani biokseera (Naturewell Industries) @ 60 g per day for 1-month, commencing 3 days after calving, in addition to the usual feeds/fodders. A clear difference was observed in milk yield from day 8 onward of experiment between groups with significant (plessthan0 0.05) higher values from day 16-52 in cows fed herbal galactogogue as compared to control, but no such distinct effect on milk constituents was observed on day 52 when analyzed. The use of herbal galactogogue significantly (p lessthan 0.05) increased the overall average of 52 days milk production, which was 9.34 ± 0.21 lit/day in supplemented as compared to 7.75 ± 0.26 lit/day in control animals. It was concluded that herbal galactogogue (Sanjivani biokseera) could increase milk yield in lactating dairy cows through its galactopoetic property and improved rumen environment.
