Variable Impact

Holstein-Friesian has been rated the number one cattle in the world as far as milk production is concerned. The productive potential is excellent in European countries. Animals of the same breed were imported to meet the milk demand of developing countries such as Pakistan. One thousand cattle from Denmark were imported in 1977–78 by the Balochistan government, and were kept at government dairy farms at seven locations (viz., Kalat, Khuzdar, Loralai, Mastung, Pishin, Quetta, and Zhob). The aim of this study was to determine the productive [age at first calving (AFC), birth weight (BWT), lactation length or milk yield (MY), milk yield per lactation (MYL), days in milk (DIM), and culling and mortality (C&L)] and reproductive potential [service period (SP), age at first service (AFS), gestation period (GP), and calving interval (CI)] of these imported animals while kept under the local conditions of Balochistan. Effect of localities with respect to the environmental data was also explored. Overall average values for AFS were 315 to 986 days with an average of 660.42 ± 12.42, GP 275 to 299 days with an average of 280.62 ± 0.25, and AFC 604 to 1299 days with an average of 944.08 ± 12.71. BWT ranged from 15 to 68 kg with an average of 30.12 ± 0.15, MY from 1471 to 7035 liters with an average of 3731.26 ± 40.52, DIM from 180 to 728 days with an average of 313.56 ± 3.83, and SP ranged from 29 to 886 days with an average of 240 ± 9.61, DP averaged 59.15 ± 20.61 days and CI ranged from 301 to 922 days with an average of 451.10 ± 5.55. The effects of year, season, age, and location were studied and the results revealed that the year influenced the AFS, AFC, BWT, and SP (P < 0.01); GP (P < 0.05) but not DIM and CI (P > 0.05). No effect of season on AFS, AFC, DIM, MY, SP or CI (P > 0.05) was observed, but GP and BWT (P < 0.05) were affected by season. Age influenced the GP and SP (P < 0.05) but not BWT, DIM, MY, and CI (P > 0.05). No effect of sex of the calves, type of birth, and calving number on GP (P > 0.05) was seen. Location of the farm did effect AFS, AFC, BWT, and MY (P < 0.01); CI (P < 0.05); but not GP, DIM, and SP (P > 0.05). In conclusion, differences in environment and seasonality had a variable impact on production parameters in Holstein-Friesian calves.

Two studies were conducted at Massey University in 1998. Expt 1 investigated the combined use of n-alkanes and 13C techniques for the estimation of individual proportions and total intakes of herbage (H) and maize silage (MS) by dairy cows. Expt 2 measured the variation in the amount of MS consumed by individual cows fed as a group. In Expt 1, six dry Holstein–Friesian cows were kept indoors and fed a diet containing one of the following H[ratio ]MS ratios (dry matter basis)[ratio ]100[ratio ]0, 80[ratio ]20, 60[ratio ]40, 40[ratio ]60, 20[ratio ]80 or 10[ratio ]90 for 25 days. Cows were dosed with a slow-release capsule containing 8 g of dotriacontane (C32) and 8 g of hexatriacontane (C36). Intake estimates were based on individual faecal samples collected twice daily during two 5-day periods. In Expt 2 (grazing trial), 12 early-lactation cows were selected from a commercial herd of 48 autumn-calving cows and blocked into pairs according to milk yield, lactation length and lactation number in a complete block randomized design. Within each pair, cows were randomly assigned to two treatments: supplemented, S (4 kg MS DM per cow after the morning milking in feed troughs) or not supplemented, NS. Another eight cows were randomly selected from the rest of the herd to increase the number of individual estimations of H and MS intakes. Cows grazed perennial ryegrass-white clover pasture during the rest of the day. In Expt 1, H[ratio ]MS ratios were not accurately predicted by the odd-chained n-alkanes, but there was a strong linear relationship between the concentration of 13C in faeces and actual H: MS ratios in the diet. The 13C method was therefore combined with the n-alkanes, resulting in accurate estimations of H and MS intakes. In Expt 2, a large variation was observed among individual cows in their daily intakes of MS (range 0·94 to 5·09 kg DM per cow, coefficient of variation = 36%), but this variation in MS intake was not associated with milk yield (P > 0·05). The results indicate that the n-alkane and 13C techniques can be successfully combined to estimate the intake of MS and H of grazing cows supplemented as a group. Under the conditions of the present study, individual cows differ considerably in the amount of maize silage consumed per day, although the reasons for this are not clear.

This study was conducted to compare the productive and reproductive performance of indigenous and crossbred cow likely Friesian, Sahiwal and Sindhi cross. A total of 180 dairy cows were selected randomly from four upazilas of Comilla district. It was observed that mean milk yield and lactation length of indigenous, Friesian cross, Sahiwal cross and Sindhi cross were 2.35±0.04, 7.36±0.11, 4.78±0.08 and 4.03±0.05 litre/day and 218.22±8.35, 284.69±1.64, 251.77±3.66 and 259.77±4.91 days respectively. It reveals that the Friesian cross is the best performer in relation to milk production and lactation length. About the reproductive performances it shows that indigenous cows need minimum (1.81±0.048) services per conception. Gestation length was shorter in case of Sahiwal cross (277.64±1.99 days) and it varies within Friesian and Sindhi cross in a short range (278.77±1.38 to 279.31±1.00 days). Calving interval was lower in Friesian crosses (413.77±53.87 days) than its counterparts. Age at puberty was shorter in Friesian cross (662.44±2.52 days). It interprets that Friesian cross was the best performer than other crossbred and indigenous cows in dairy potentialities. DOI: http://dx.doi.org/10.3329/bjas.v37i1.9866 BJAS 2008; 37(1): 39-43

The data on 481 lactation records including 204 records of Red Kandhari cows and 277 records of Jersey x Red Kandhari crossbred cows were collected from Cattle Unit, College of Veterinary and Animal Sciences, (MAFSU), Parbhani over a period of 27 years (1977-2004). The lactation milk yield for first, second, third, fourth and fifth and above lactations for Red Kandhari cows were 375.16±34.15 kg, 458.17±37.62 kg, 450.91±26.74 kg, 532.69±67.74 kg and 674.29±82.09 kg, respectively and for Jersey x Red Kandhari crossbred were 1100.28±73.18 Kg, 1318.50±135.20 Kg and 1353.92±91.61 Kg, 1549.77±188.47 kg and 1438.37±48.89 kg, respectively. The first lactation length and first dry period in Red Kandhari cows were 273.30±10.33 days and 239.05±21.88 days, while in Jersey x Red Kandhari crossbred cows were 302.68±9.19 days and 86.72±8.90 days, respectively. The least square analysis of variance for first, second and third and more than three lactations for lactation milk yield, lactation length and dry period showed that the genetic group had significant source of variation for all traits in all lactations except first and second lactation length. Sire within genetic group had significant source of variation for first lactation milk yield and all traits of third and more than three lactations. Season and period of calving had non-significant influence on all the traits in all lactations except first dry period. It was also observed that the improved performance in all the traits under study in Red Kandhari cow and Jersey x Red Kandhari crossbred cow was observed in fourth and fifth and above lactations.

Lactation Cycle

Background: The study was conducted to unravel the consequences of abnormal lactation lengths (Extremely short, short, prolong and extremely prolong lactation length) on production and reproduction traits of crossbred cattle (Red Dane x Sahiwal x Holstein Friesian), which otherwise remains unutilized in routine breeding data analysis owing to normalization and standardization of lactation lengths. Methods: The performance data of 2541 lactations of 1001 crossbred cattle, sired by 146 bulls over a period of 30 years maintained at the Livestock Farms of Guru Angad Dev Veterinary and Animal Sciences University (GADVASU), Ludhiana were used for this study. The data on production and reproduction traits were analysed using general linear model procedures based on extremely short ( less than 102 days), short (102-179 days), prolong (483 - 560 days) and extremely prolong (≥ 560 days) lactation lengths on the basis of mean lactation length and its standard deviation. Result: Result indicated that the alteration of lactation lengths affected all important performance traits of crossbred cattle in contemporary as well as in next lactation. The values of 305 days milk yield, lactation milk yield, average fat (%), 305 days fat yield and lactation fat yield of contemporary lactation cycle were higher (P≤0.05) for the extremely prolong lactation length and reduced for shorter lactations. Similar trend was seen for next lactation cycle of the animal having abnormal lactation length in previous lactation cycle for all traits except calf birth weight, whereas days to reach peak yield and fat yield traits were not significantly affected by lactation length classes. The preferred lactation length for crossbred cattle for optimum performance was concluded as 180 to 483 days ranging one standard deviation from mean lactation length, covering more than 72% of population; however, it needs further studies to break it into groups in terms of productive life and economical merits. Farmers should avoid breeding of animal having extremely short and short lactation lengths, as their production and reproductive traits are lower in successive production cycle.

Mastitis is a complex disease causing inflammation of the udder, which has been estimated to cost the dairy farmer between £40-£117/cow per year (Stott et al., 2002). Economic loss occurs as a result of discarded milk, reduced milk yield and milk quality, increased vet costs and an increase in replacement costs. The objective of this study was to examine the effect of breed on the incidence of mastitis and somatic cell counts and milk production capabilities of Holstein Friesian, Brown Swiss and Brown Swiss crossbred cows.

The study was undertaken to evaluate the effect of different macro climatic variables on lactation milk yield and lactation length of Holdeo (Holstein Friesian x Deoni) crossbred cattle. Milk data of 145 Holdeo crossbred cows with 619 lactation records and the meteorological data over a period of 15 years (1995-2009) were obtained from Cattle Cross Breeding Project, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani and University Meteorological Observatory, respectively. It was observed that maximum temperature has significant correlation with lactation milk yield; whereas maximum temperature, minimum temperature, sunshine hours and wind speed have significant correlation with lactation length. Regression analysis indicated that all the climatic variables except minimum temperature exhibited significant regression results with lactation milk yield, and maximum temperature, minimum temperature and maximum humidity have significant regression results with lactation length. All the climatic variables considered in the study accounted for 75 % and 65 % direct variation on lactation milk yield and lactation length, respectively, as verified by the value of coefficient of determination (R2). It was observed that lactation milk yield (1136.56 + 21.04 kg.) and lactation length (295.29 + 5.51 days) were highest among the cows calved during winter season as compared to rainy and summer season. All the climatic variables considered in the study accounted for 57% , 56 % and 48 % direct variation on milk yield and 68% , 53 % and 46 % direct variation on lactation length in rainy, winter and summer season, respectively, as verified by the value of coefficient of determination (R2). This research indicated that crossbred cows were sensitive to seasonal changes on their lactation performance. The optimum ranges of temperature; humidity and THI for better performance of crossbred in subtropical region of India were found to be 19-26 oC, 52-66 % and 65-68 %, respectively.
