“…Higher peak yield and milk production observed in G2 may be attributed to bypass fat supplementation which increased the energy density of the ration resulting in reducing the deleterious effect of negative energy balance. The present results are in line with the findings of Fahey et al (2002), McNamara et al (2003), Mishra et al (2004), and Ben Salem and Bouraoui (2008). The average milk production was 7.4% higher (P<0.05) in G2 than that of G1 in the 90 days carry over period.…”

Objectives of the present study were to evaluate the effects of supplementation of bypass fat on milk production and reproductive performance of crossbred cows. Nineteen multiparous crossbred cows (2-4 lactation) were divided in two groups on the basis of most probable production ability (MPPA). The animals in group 1 (nine cows, MPPA 3,441.32 kg, control group G1) were fed chaffed wheat straw, chopped green maize, and concentrate mixture as per requirements while the animals in group 2 (10 cows, MPPA 3,457.2 kg, treatment group G2) were fed the same ration supplemented with 2.5% bypass fat (on DMI basis). The cows of G2 were supplemented bypass fat 40 days prepartum to 90 days postpartum and carry over effect of supplementation on milk production and reproductive parameters was monitored up to 210 days of lactation. Average birth weights of the calves were 24.94 and 27.95 kg in G1 and G2, respectively. The calving per cent in G1 (88.88%) was lower than that of G2 (100%). The time taken for expulsion of fetal membranes was decreased (P<0.05) by 5.4 h in G2 compared to G1. Days required for involution of uterus was less (P<0.05) in G2 (35.40 days) than that of G1 (49.44 days). Less number of cases of retention of fetal membranes (RFM) and metritis were observed in G2 as compared to that of G1. The average milk yield (210 days) in G2 was higher (P<0.05) than that of G1 (18.65 vs 17.57 kg/day). Similarly, the milk yield during the carry over period (90 days) was higher (P<0.05) in G2 than that of G1 (14.81 vs 13.79 kg/day). The time required for onset of cyclicity was reduced (P<0.05) by 6.5 days in G2 as compared to that of G1. The service period and AI per conception were also reduced (P<0.05) in G2 while bypass fat feeding showed no effect on conception rate (P<0.80). There were no differences between the two groups in plasma cholesterol, progesterone and insulin concentrations. Hence, it was concluded that bypass fat supplementation at 2.5% of DMI increased the milk production and reduced the time required for involution of uterus and commencement of cyclicity. AI per conception, incidences of metritis and RFM were also reduced on supplementing bypass fat.

“…Furthermore, there was no direct relationship between plasma P 4 , E 2 and PGFM, but a higher E 2 : P 4 ratio was related to an increased concentration of PGFM on both sampling days. An increase in PGFM has been reported previously for dietary (Fahey et al, 2002;Petit et al, 2004) and intravenously infused (Filley et al, 1999) sources of linoleic acid. However, results from trials involving fish meal and fish oil supplementation have been inconsistent in their effects on PGFM, with some reporting reductions (Mattos et al, 2002 and2004), and others, reporting no effect (Wamsley et al, 2005;Heravi Moussavi et al, 2007).…”

The objective of this experiment was to examine the effects of dietary n-3 or n-6 fatty acid (FA) supplementation on blood FA, metabolite and hormone concentrations, follicle size and dynamics and corpus luteum (CL) size. Reproductively normal heifers (n 5 24) were individually fed diets of chopped straw and concentrate containing either (i) no added lipid (CON; n 5 8); (ii) 2% added fat as whole raw soya beans (WSB, n-6; n 5 8); or (iii) 2% added fat as fish oil (FO, n-3; n 5 8). Following oestrous cycle synchronisation, blood samples were collected at appropriate times and intervals for the measurement of hormones, FAs and metabolites. On days 15 and 16 of the cycle, animals were subjected to an intravenous oxytocin challenge and prostaglandin F 2a (PGF 2a ) response, measured as venous concentrations of 13,14-dihydro-15-keto PGF 2a (PGFM). Dry matter intake and average daily gain were similar among treatments ( P . 0.05). Plasma concentration of linoleic acid was highest on WSB ( P , 0.05), while eicosapentaenoic (EPA, n-3; P , 0.0001) and docosahexaenoic acid (DHA, n-3; P , 0.0001) were greatest in the FO group. Plasma concentrations of arachidonic acid were higher on FO ( P , 0.05) compared with CON and WSB. Plasma triglyceride concentrations increased, while b-hydroxybutyrate (BHBA) decreased with time on all diets (P , 0.05). There was a diet 3 time interaction ( P , 0.01) for non-esterified fatty acid (NEFA) concentrations. Plasma cholesterol was higher on WSB and FO ( P , 0.01) compared with CON. Progesterone (P 4 ) and oestradiol (E 2 ) concentrations, as well as follicle growth rate and CL diameter were similar across diets ( P . 0.05). There was a diet 3 day interaction for PGFM ( P , 0.01). When corrected for systemic E 2 : P 4 ratio, day 15 concentrations of PGFM were higher in the WSB group at 15 and 30 min ( P , 0.01) post oxytocin administration compared with CON and FO, which were similar ( P . 0.05). Concentrations of PGFM on day 16 were similar for WSB and FO and were greater than CON at 15 ( P , 0.01) and 45 min ( P , 0.05) post oxytocin administration, and at 30 min for FO ( P , 0.05). With the exception of PGFM, dietary lipid source did not affect the reproductive variables measured.

“…In the study of Sajith et al (2008) got improved quality milk production without affecting the digestibility of nutrients through incorporation of polyunsaturated calcium salts of fatty acids at a 4% level in the concentrate mixture. By using calcium salts of fatty acids Rabiee et al (2012) and Fahey et al (2002) also obtained the similar result. There was no significant (p>0.05) difference for the parameters of milk protein, lactose, total minerals and SNF.…”

Keeping consideration on increasing quality milk production through addition of conventional fat, an experiment accords CRD design was conducted at Bangladesh Livestock Research Institute, Savar, Dhaka for a period of 30 days including 5 days of digestibility trial. Twenty lactating Pabna cattle of average 250.1 ± 13.64 kg (Bos indicus) of initial body weight with average milk yield of 2.88 ± 0.38 kg were selected and divided into four groups randomly having five cows in each. The imposed treatments were T 0 , T 1 , T 2 , and T 3 ; in where T o = German grass + Concentrate mixture without Ca salt of fatty acid + 2.5 % DCP, T 1 = German grass + Concentrate mixture + 2.5 % soybean based Ca salt of fatty acid, T 2 = German grass + Concentrate mixture + 2.5 % mustard based Ca salt of fatty acid and T 3 = German grass + Concentrate mixture + 2.5% palm-oil based Ca salt of fatty acid. The result showed that, calcium salt of fatty acid influenced to increase of milk yield significantly among (P<0.001) the treatments; in where highest yield gained in T 1 (3.53 kg d -1
