Background: Buffaloes are economically important in particular region and also buffalo milk are nutritionally rich. In Konkan region, buffalo should be rarely used only to get female buffalo for milk production. To improve the non-descript buffalo population for milk production and reproduction performance. Methods: During survey period January, 2021 to February, 2021, record of 400 non-descript buffalo, 270 non-descript buffalo having more than 4 years age old to be selected. Result: The average daily milk yield, peak milk yield, total lactation milk yield, lactation length and dry period in non-descript buffaloes were 6.45±0.16 liters, 7.6±0.14 liters, 2007.66±45.83 liters, 302.86±0.34 days and 146.66±0.48 days, respectively. The average age at first calving, calving interval, service period, gestation period and number of calving were 45.96±0.18 months, 449.30±0.53 days, 128.86±0.31 days, 303.66±0.49 days, 2.72±0.12 numbers, respectively and autumn season of calving was more than another season.

SummaryDuring the period 1962–73, the majority of the 92 lactations of imported British Friesian animals were initiated during the dry season (October–March). The following average values were obtained: lifetime number of lactations, 4·5; lifetime milk production, 9392 kg; age at producing first live calf, 39·6 months; milk yield of nine lactations, 2159 kg; lactation length, 336·5 days; daily milk yield, 6·3 kg; 305-day milk yield, 2012 kg; dry period, 173 days.Milk production was highest in the fourth lactation when the animals averaged 7 years old. Differences in milk yield among lactations were small. Peak daily milk yield was greatest in the third lactation and was reached within the first 21 days of each of the first four lactations. A second but lower peak with the highest milk production persistencies at a later stage of lactation apparently depended on feed availability. The 305-day milk yield was reasonably predicted from the 100- and 200-day yields.Lactations subsequent to abortions and stillbirths were slightly longer, gave less milk (P > 0·05) and were followed by longer dry periods than those initiated by normal births.

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.

In the work carried out at Dzerzhinsky Plemzavod OJSC in the Yaroslavl region of the Yaroslavl region, the effect of the feed additive, Yarosil, fed to heifers during pregnancy, on young cows, was studied. It was established that the feed additive "Yarosil" had a prolonged positive effect on the body of first-calf heifers, which was expressed in improving the quality of household and normalizing physiological parameters. Feeding the feed additive “Yarosil” in the amount of 35 ml per animal per day increased the milk productivity of young cows for lactation by 562.5 kg - 12.10%, the average daily milk yield by 1.81 kg - 12.03%, while reducing feed costs by 1 kg of milk per 10.55% feed. units, reduced the service period by 21.2–16.77% of the day, the insemination index by 26.70%. The economic effect per heifer increased due to milk production by 3375.00 rubles. - 12.10%, sperm dose saving by 96.90 rubles - 26.70%. With an increase in the input rate by a factor of 2 (70 ml per animal per day), milk production per lactation increased by 1111.6 kg - 23.91%, average daily milk yield by 3.22 kg - 21.39%, while reducing feed costs by 1 kg of milk per 18.95%, feed. units, the service period decreased by 24,3–19,22% of the day, the insemination index by 27.74%. The economic effect per one heifer increased due to: milk production by 6669.60 - 23.91% rubles, saving sperm doses by 100.70 – 27.74% rubles. Regardless of the input rate, the feed additive “Yarosil” reduced the incidence by 16,67%, ensured 100% safety without the use of medical agents, increasing this indicator by 8.33%, and increased the economic effect due to the absence of the need for treatment costs by 7714, 00 rub., And safety for 28064.77 rub. The research results allowed to identify additional reserves for increasing the efficiency of the livestock industry with the rational use of feed, based on the use of feed additives "Yarosil" in the amount of 70 ml per animal per day.

This survey study was conducted in Tangail, Jamalpur, Bogra, Sirajganj, Pabna and Thakurgaon districts for household farming, and in Bhola, Noakhali, Lakshmipur and Patuakhali districts for bathan farming to undertake an assessment on the management factors in household and bathan farming for identifying the potentiality and constraints in milk production from buffalo. A 90 number of pre-designed questionnaire was used for data collection by direct interviewing of buffalo farmers. From this study, it was revealed that 82% of the farmers have 1 to 3 buffalo per household and 73% of the farmers have 51 to 200 buffalo per bathan. Buffaloes were raised in homestead and approximately 5-7 hours were grazes per day in household farming. Small quantity of concentrate feeds were offered to buffalo by the rich farmers during dry season. On the other hand, in bathan, farmers were fully depended to feed the buffalo on grazing at public land. In household, the average daily milk production was 3 to 8 liters and total milk yield was 799 liters in a lactation length of 270 days. In bathan, the average daily milk production was 1 to 2 liters and total milk yield was 435 liters in a lactation length of 215 days. The average age of first calving, service per conception, gestation period and calving interval were 39 months, 1.9 numbers, 310 days and 490 days, respectively in household farming. The average age of first calving, service per conception, gestation period and calving interval were 40 months, 2.1 numbers, 315 days and 530 days, respectively in bathan farming; however, further study is required on the buffalo nutrition in the bathan farming.Bang.

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.

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.
