Body condition of lactating dairy cows varies at different stages of lactation. Cows usually mobilise their body reserves to provide energy and protein for milk production in early lactation, and gain weight to deposit energy and protein for pregnancy at a later stage. The objective of the present study was to examine relationships between body condition score (CS) and body concentration of lipid, CP and energy.

Abstract The objective of this study was to evaluate the milk production, body weight, and body condition score (BCS) of ewes fed with different energy levels. Seventy-one ewes were used and distributed in three treatments according to the metabolizable energy (ME, Mcal/kg) levels in the diet: CTL = according to the NRC (2007) recommendation for each stage (gestation and lactation); PLUS = CTL plus 10% of ME per kilogram of dry matter; LESS = CTL less 10% ME per kilogram of dry matter. Body weight and body condition score were evaluated a week before the expected date of parturition, a week after giving birth, and at weaning (60 days). Dairy production was evaluated at 20, 30, 40, 50 and 60 days after giving birth by the indirect method of the two weighing. The experimental design was analyzed as randomized complete blocks. There were no differences on milk production during almost all the lactation curve. Only on day 50 (P = 0.051), CTL was still at peak, while LESS and PLUS had already decreased their production. However, at 60 days, all treatments were already with low production, justifying weaning in this period. Results of weight and BCS showed a significant difference in all periods evaluates. Ewes in the PLUS diet had greater BW and BCS. The BCS before giving birth is expected to be over 3.5 and treatment LESS was the only one that did not achieve this score (2.66, 3.37, 3.83 for LESS, CTL, and PLUS, respectively). At weaning, ewes fed PLUS and CTL had BCS of 3.51 and 2.92, respectively, but treatment LESS had only 1.82. That is prejudicial for the next mating seasonal and this animal. We concluded that LESS diet interfered with the body reserves of sheep.

A review of published leptin data for growing lambs, older ewes and mature dairy cows in late lactation showed that only 0.30-0.37 of the variation in blood leptin concentration was explained by differences in body fat variably expressed as % of liveweight (LW), backfat thickness and body condition score (BCS) respectively (Wylieet al., 2002). In dairy cows between 15d and 226d postpartum, Wylieet al(2002) observed no overall correlation between leptin at slaughter and lipid expressed as % of LW, empty body weight or carcase weight and only a weak correlation in cows in mid-lactation. Losses of fat during early lactation may ‘uncouple’ the link between leptin and fat and produce a bias across all of lactation. Another explanation is that leptin may be more closely linked with lipogenesis than with the amount of stored fat. This study revisits some metabolite and hormone data from a previous investigation of IGF-1 changes in fed, fasted and re-fed sheep in the light of more recently obtained leptin concentrations in the same animals.

The study was conducted to investigate the effect of α-tocopherol acetate and zinc on body condition, energy metabolites and milk production in Karan Fries cows. Sixteen pregnant Karan Fries cows were selected two months before expected date of calving. The experimental animals were randomly divided in to two groups namely control group (eight cows) and treatment group (eight cows). Treatment group cows were supplemented with α-tocopherol acetate @ 1000 IU/day/cow and zinc @ 60 ppm/day/cow. Blood samples were collected on the days -60, -45, -30, -15, -7, 0, +7, +15, +30, +45 and +60 with respect to expected date of calving. The body weight and body condition score of all the experimental animals was recorded on the day of blood collection. After calving milk yield of the experimental animals was recorded till 60 days in milk. At parturition, body weight and body condition score differ significantly (P<0.001) in treatment group than control group (448.00 vs. 416.33 Kg and 4.42 vs. 4.17, respectively). The overall mean (±SEM) of plasma glucose was found to be significantly (P<0.001) higher in treatment group as compared to control group (62.39±1.23 vs. 57.44±1.59 mg/dl). The overall mean of non-esterified fatty acids was found to be significantly (P<0.001) lower in treatment group as compared to control group (197.10±3.38 vs. 239.21±3.48 μM/L). The overall mean of milk yield was found significantly (P<0.001) higher in treatment group as compared to control group (20.48±1.16 vs. 16.94±1.38 Kg/day i.e. 20.90%). The results of this study indicated that supplementation of antioxidants like α-tocopherol acetate and zinc have beneficial effects on milk production along with improved body condition and metabolic status of the animals.
