Twenty five buffalo cows of Mothbaria Upazila of Pirojpur district and another twenty five indigenous buffalo cows of Pathorghata Upazila of Borguna district of Bangladesh were randomly selected and interviewed to collect data on reproductivity (gestation length, birth weight, age of first calving, post partum heat and calving interval), productivity (lactation length and daily milk yield) and management system (general management, housing, feeding, calf rearing and treatment facilities) of indigenous buffalo cows using pre-tested questionnaire during the period from January to June 2010. The reproductive parameters including gestation length, birth weight, age of first calving, post partum heat and calving interval of Mothbaria Upazila of Pirojpur district were 319.56 ± 5.93 days, 24.28 ± 4 kilograms, 50.88 ± 1.71 months, 153.6 ± 6.13 days, 547.92 ± 10.88 days respectively whereas in case of Pathorghata Upazila of Borguna district these parameters were 319.12 ± 4.69 days, 24.12 ± 3.6 kilograms, 51 ± 1.8 months, 153.44 ± 6.78 days, 547.24 ± 14.32 days respectively. The productive parameters including lactation length and daily milk yield of Mothbaria Upazila of Pirojpur district were 286.12 ± 11.27 days and 3.33 ± 0.68 liters/day respectively while in case of Pathorghata Upazila of Borguna district these parameters 290.44 ± 10.92 days and 3.43 ± 0.744 liters/day respectively. So, reproduction and production are almost regular comparing with other published reports with the exception of age of first calving which is almost 12 months later than the buffaloes of other countries. It could be concluded that the buffalo owners of these areas do not follow any scientific method of buffalo husbandry; they just follow traditional rearing system. The farmers mostly use buffaloes for draught purpose in these costal areas.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19113 Progress. Agric. 24(1&2): 117 - 122, 2013

A survey was conducted to estimate the productive and reproductive performances of RCC in Rawjan, Chandanaish, Potia, Satkania and Anowara upazillas of Chittagong, Bangladesh. The farmers of the study areas holding Red Chittagong Cattle (RCC) were divided into large (>1.50 acre), medium (>1.0-1.5 acre), marginal (>0.5-1.0 acre) and landless (>0-0.5 acre) categories. Existing feeding and rearing practices, productive and reproductive performances of RCC were investigated. It was found that, most of the RCCs (82%) were reared mainly by the marginal farmers. In between May to September, there was a severe shortage of feeds and fodders for RCC. However, despite severe shortage, the farmers were not interested to cultivate fodder. The degree of shortage for feed round the year had significant variation (p<0.01) among the farmers of all categories. Similar to feed shortage, the tendency of growing non-legume crops had marked variation (P<0.01) among the farmers of all categories. Birth weight, weaning weight, daily milk yield, lactation length, calving interval, age at first service, age at first calving and gestation length were 14.5 kg, 64.6 kg, 2.1 liters, 216 days, 14 months, 2.7 years, 42 months and 279.9 days respectively. It could therefore be inferred that, productivity of RCC may be increased by improving feeding systems in the study areas.http://dx.doi.org/10.3329/bjas.v41i1.11973

Accumulated five years data on 197 kids of 15 Black Bengal bucks in the nucleus breeding flock of Black Bengal goats were analyzed for the study of production traits. The traits considered were birth weight, weight at every 3- month interval up to 12-month, semen characteristics and milk yield. Semen parameters were evaluated from 450 ejaculates of 15 Black Bengal bucks collected twice a week by artificial vagina method and daily milk yield of Black Bengal goats were estimated from the analysis of 57 lactation records of 30 does. The significance of fixed effects sex of kid, parity, litter size, season, age, body weight and scrotal circumferance were analyzed using least-squares analyses of variance of the general linear model (GLM) procedure of the Statistical Analysis System (SAS, 1998). Least-squares means for body weights at birth, 3, 6, 9 and 12-month of age were 1.3, 4.8, 8.0, 11.1 and 14.0 kg, respectively. Body weights at 3, 6, 9 and 12-month of age except at birth were affected by the sex of kids (p<0.05). Type of birth and parity of dam had the significant affect (p<0.05) on birth weight, whereas season of birth had significant (p<0.05) effect on the body weight. The least-squares means of semen volume (ml/ejaculate), sperm concentration (109/ml), mass motility (%), live spermatozoa (%) and normal spermatozoa (%) were 0.5, 2.4, 80.0, 86.5 and 89.3, respectively. Age of bucks had significant (p<0.01) affect on semen volume, sperm concentration. Body weight had a significant (p<0.05) effect on semen volume only. Least-squares mean of daily milk yield was 379.9 lit.. Milk yields was significantly (p<0.01) affected by litter size and season of kidding. It is suggested that nongenetic factors should be adopted as a technique for improving the productive traits. DOI: http://dx.doi.org/10.3329/jbau.v11i1.18217 J. Bangladesh Agril.

The current study was carried out using data of the Nucleus Herd and Community Herd of Red Chittagong Cattle (RCC) established through USDA funded Red Chittagong Cattle project under the Department of Animal Breeding and Genetics, BAU, Mymensingh. Data on 151 calves and 75 lactating cows were analyzed. The estimated heritability values were 0.45 ± 0.05 for birth weight, 0.48 ± 0.05 for weaning weight, 0.41 ± 0.08 for pre-weaning daily gain, 0.47 ± 0.06 for lactation length, 0.43 ± 0.07 for lactation milk yield and 0.35 ± 0.09 for average daily milk yield. The highest Breeding Value (BV) were for birth weight (3.2 kg), weaning weight (24.46 kg), pre-weaning daily gain (82.39g), lactation length (52.25 days), lactation milk yield (186.04 kg) and average daily milk yield (0.66 kg). The minimum and maximum phenotypic index values by using phenotypic parameters were for growth traits (1196.24 and 4713.24) and milk production traits (8573.93 and 40670.81). The minimum and maximum genetic index values by using breeding values were for growth traits (1812.49 and 2870.21) and milk production traits (-1812.49 and 2870.21). All the estimated index values can be used in animal selection and breeding programs for RCC improvement and similar index selection can be applied for other indigenous cattle development programs in Bangladesh or elsewhere.

The present study was aimed to investigate the effects of body weight and scrotal circumference on semen production traits of 136 crossbred Jersey bulls, which were maintained at three frozen semen stations of Tamil Nadu, India. Semen production traits such as semen volume, sperm concentration, mass activity, initial sperm motility, post-thaw motility and number of doses per ejaculate were taken for this study. The overall mean values for semen volume (ml), sperm concentration (millions per ml), mass activity (0 to 5 scale), initial sperm motility (per cent), postthaw motility (per cent) and number of doses per ejaculate were 4.18 ± 0.02, 1052.80 ± 7.26, 2.09 ± 0.07, 63.36 ± 0.00, 50.52 ± 0.00 and 215.50 ± 2.01 respectively. From this study, it revealed that the body weight and scrotal circumference of bulls significantly influenced all semen production traits except mass activity. Bulls having a body weight between 350 to 550 kg produced better quality semen and more number of frozen semen doses per ejaculate. When the scrotal circumference was >36 cm, majority of the semen production traits showed better values. The body weight was positively and significantly correlated with scrotal circumference, Semen volume and number of frozen semen doses produced per ejaculate. The scrotal circumference was positively and significantly correlated with semen volume, mass activity and number of doses per ejaculate; negatively and significantly correlated with initial sperm motiltiy.

Production traits of 60 indigenous (Desi), 20 Friesian × Desi and 20 Sahiwal × Desi cows were recorded in six char villages of Sariakandi upazila (Sub-district) of Bogra district. The mean (± SD) daily milk yields were 1.7 ± 0.6, 6.3 ± 1.2 and 5.1 ± 1.0 litres, respectively. The lactation lengths, ages at puberty, gestation lengths, calving intervals, numbers of services per conception, intervals between calving and first oestrus were 217.9 ± 18.7, 253.8 ± 21.9, 240.8 ± 15.7 days; 27.4 ± 2.7, 23.9 ± 2.0, 26.2 ± 2.4 months; 277.4 ± 4.2, 278.3 ± 4.2, 278.3 ± 4.0 days; 494.8 ± 27.3, 487.5 ± 17.4, 493.3 ± 16.2 days; 1.3 ± 0.5, 1.7 ± 0.6, 1.6 ± 0.5; 145.6 ± 27.4, 166.8 ± 33.0 and 170.5 ± 34.9 days, respectively. Daily milk yield and lactation length were significantly (p<0.01) better for cross-bred cows than for Desi, and age at puberty was significantly (p<0.01) better for Friesian-cross cows than for Desi, while number of services per pregnancy and onset of post partum oestrus were significantly (p<0.01) better for Desi than for cross-bred cows. There were no significant differences in gestation length and calving interval. It is suggested that the overall productive and reproductive performance of Friesian × Desi and Sahiwal × Desi cows were better than those of Desi cows. DOI: 10.3329/bvet.v25i2.4620 Bangl. vet. 2008.

Abstract. Data from the Butana herd of Atbara Livestock Research Station were analyzed for the period 1949–1999. The least squares means for age at first calving, calving interval, milk yield per lactation, daily milk yield, lactation length and dry period were 45.05 ± 3.56 months, 382.38 ± 8.30 days, 1662.57 ± 108.96 kg, 6.10 ± 0.40 kg, 268.17 ± 5.56 days and 119.10 ± 8.30 days, respectively. The analysis of variance revealed that the sire and parity number influenced the studied traits, while year-season of calving influenced the milk yield per lactation, daily milk yield and lactation length. Linear and quadratic regressions on lactation length significantly influenced milk yield per lactation and daily milk yield. Heritability estimates for age at first calving, calving interval, milk yield per lactation, daily milk yield, lactation length and dry period were 0.19 ± 0.07, 0.09 ± 0.03, 0.26 ± 0.06, 0.27 ± 0.07, 0.04 ± 0.02, and 0.09 ± 0.03, respectively. This study highlighted the importance of conserving the indigenous dairy cattle breeds for future generations. The presence of significant variation and the corresponding heritability estimates give promise of reasonable genetic improvement under selective breeding with respect to milk yield characters.

The present study was undertaken to estimate effects of environmental factors onmilk production traits in Red Chittagong Cattle (RCC). A total of 103 milk yield recordsof 45 RCC cows obtained between 2005 and 2009 were analysed. Actual lactation yield,lactation length, daily milk yield and dry period were estimated as 500.7 ± 19.3 kg, 259.6 ±6.2 days, 1.9 ± 0.1 kg and 162.4 ± 7.7 days, respectively. Age and season correctedlactation yield, 305 day milk yield and daily milk yield were estimated as 605.4 ± 22.9,677.1 ± 19.4 and 2.2 ± 0.1 kg, respectively. Sex of calf and season of birth did notsignificantly (P>0.05) affect production, but lactation order significantly (P<0.05) affectedproduction except lactation length. Year of birth had no effect (P>0.05) on the traitsanalysed except daily milk yield (P<0.05). Calving age significantly (P<0.05) affectedlactation yield but did not other traits. Cows in 5th lactation produced highest total (604.3± 69.3 kg) and daily milk yield (2.17 ± 1.8 kg). Cows aged 6 – 7 years had best lactationyield (576.8 ± 60.5 kg).(Bangl. vet. 2010.

Abstract. The data obtained from the dairy herd of the Arab Company for Agricultural Production and Processing (ACAPP) in a semi arid area 40 km south of Khartoum involved 337 cows with a total of 1049 records from 16 years between 1986 and 2002. The least squares means for age at first calving, calving interval, days open, lactation milk yield, daily milk yield, lactation length and dry period were 29.76±0.40 months, 433.12 ± 6.70 days, 167.79±7.08 days, 3475.53±78.89 kg, 12.29±0.28 kg, 294.10±3.62 days and 164.08 ± 6.70 days, respectively. The analysis of variance showed that the parity number had significant (p<0.05) influences on all studied traits, while year-season of calving influenced (p<0.05) age at first calving, milk yield per lactation and daily milk yield. The sire of cow influenced (p<0.05) lactation yield, daily yield, lactation length and days open. The effects of linear and quadratic regressions of both lactation yield and daily yield on length of lactation were also highly significant (p<0.01). Heritability estimates of age at first calving, calving interval, milk yield per lactation, daily milk yield, lactation length and dry period were generally low (0.098±0.104, 0.047±0.046, 0.130±0.042, 0.123±0.041, 0.172±0.062 and 0.044±0.031, respectively) except the heritability of days open which was 0.51±0.37. The productivity of the herd in this study which averaged 12.3 kg/cow/day was much lower than the expected productivity of Holstein Friesian cows, which reflects the negative impact of the prevalent environment in the Sudan. More records and economic data are required to examine the economic feasibility of raising pure Friesians under Sudan conditions.

Abstract This study assessed daily milk yield (DMY), 100-day (MY100), and 305-day (MY305) milk yield, and lactation length (LL) in purebred Ankole cattle and Ankole crossbreds, and the influence of environmental factors on these traits. Milk yield data were obtained for 865 cows and 1234 lactations and analyzed using a mixed linear model. The overall least squares mean of DMY, MY100, and MY305 across breed groups was 2.7 L (N = 1234, SD = 1.7), 262 L (N = 959, SD = 176), and 759 L (N = 448, SD = 439), respectively, while the average lactation length was 256 days (N = 960, SD = 122). All factors included (breed group, season and year of calving, and parity) were significant for yield traits, except season of calving for MY305. First-parity cows had the lowest milk production, and fourth-parity cows the highest. For all traits, pure Ankole cows had the lowest milk yield. Among the crossbreds, there was no significant difference between Ankole × Friesian, Ankole-Jersey mother × Sahiwal sire, and Ankole-Sahiwal mother × Jersey sire, or between Ankole × Sahiwal and Ankole-Sahiwal mother × Sahiwal sire. It was concluded that Ankole crosses with Friesian or Jersey can be beneficial, even under a management system of limited nutrition as in Rwanda.
