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.

Present study was carried out with the aim to determine the effect of genetic and non-genetic factors on milk production efficiency traits and their genetic control. Data on milk production efficiency traits i.e. total milk yield per day of lactation length and total milk yield per day of calving interval in Jersey crossbred animals maintained at organized herd of ICARNational Dairy Research Institute, Eastern Regional Station, Kalyani, Nadia, West Bengal spread over 29 years (1986-2014) were analyzed in the study. The overall least-squares means of total milk yield per day of lactation length and total milk yield per day of calving interval were estimated as 6.97±0.21 and 6.02±0.23 kg/day, respectively. The data was grouped into different sub-classes of season of calving, period of calving, parity and genetic group of animals. The random effect of sire had shown significant (p<0.01) influence on milk production efficiency traits. Various environment factors significantly affected the milk production efficiency traits indicating the scope of improvement in management of these crossbred animals. The heritability estimates of 0.54 for TMY/LL and 0.63 for TMY/CI were high in magnitude which suggests that fast genetic progress can be made, if these animals are selected based on the milk production efficiency traits.

Samples of milk obtained in the course of evening and morning milking performed in variable time intervals of either 11 and 13 hours (n = 1.282) or 10 and 14 hours (n = 370) were collected with the aim to quantify the effect of the length of a variable (asymmetric) time interval between evening and morning milking on the total amount and composition of daily milk production of dairy cows. Milk samples were analysed in an accredited (EN ISO 17025) laboratory in Brno-Tuřany (Czech Republic) and the following contents of individual milk components were estimated: fat (F; g.100g−1), total protein (TP; g.100g−1), lactose (L; lactose monohydrate; g.100g−1), and somatic cell counts (SCC; ­103.ml−1) were estimated in. It was found out that with the increasing total daily milk production the shares of evening and morning milk yield increased as well; however, the percentages of evening and/or morning yields in the total yield remained practically unchanged and represented 43.5 % and 56.5% or 40.4 % and 59.6 % in variants with intervals of 11 and 13 hours and/or 10 and 14 hours, respectively. In the variant with the milking interval of 11 and 13 hours, values of correlation coefficients between the above parameters (i.e. F, TP, L, SCC, and log SCC) of evening and morning milk yields on the one hand and the total milk performance on the other ranged from the minimum r = 0.896 (F) to the maximum r = 0.980 (TP). In the variant with the interval of 10 and 14 hours, the corresponding values of correlation coefficients were r = 0.848 (F) and r = 0.983 (TP). These correlations were statistically highly significant in all cases (P ≤ 0.001). Further, linear regression equations enabling the estimation of milk parameters of the total milk yield on the base of results obtained in evening and morning milking was calculated as well. Values of coefficients of determination (R2) of these equations ranged from 0.803 (F) to 0.960 (TP) and from 0.718 (F) to 0.966 (TP) for intervals of 11:13 hours and of 10:14 hours, respectively.

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

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.

The aim of the paper was to prove the accuracy of various statistical models of vari&shy;ance analysis for estimation of systematic factors that influence milk yield and fat and protein content in dairy goats. Data on daily milk production recorded by methods AT, AC or A4 for the population of Czech White Shorthaired Goats over 1992&ndash;2002 was used for calculations. A total of 78 736 test day from 6 234 goats were analysed. Average daily milk production was 3.09 kg with 3.72% of fat and 2.84% of protein. Variability of examined traits was significantly influenced by effects of herd-year or herd-test day, litter size, parity, season of kidding, stage of lactation and the combined effect parity-year-season of kidding. The variants of model equations in which complex effects of herd-year were replaced by effects of herd-test day showed higher values of reliability for the three traits analysed. &nbsp;

Daily Milk Yield

In the herd of Nganda cattle at the Government Livestock Experiment Station, Entebbe, Uganda, it was found that of the known environmental factors affecting milk production, the more important ones were age (in lactations) and length of the calving interval preceding the second and third lactations. The correlations between performance in different lactations of the same animal were high for lactation milk yield (0·73) and average daily milk yield (0·62) and low for calving interval (0·21) and dry period (0·15). The repeatability of lactation length was intermediate (0·42). The heritability values were around 0·3 for the weight measurements, around 0·2 for yield characteristics and around 0·1 for length of lactation and age at first calving.The sires used in the breeding programme at Entebbe made little impact on production performance in the herd. The estimated genetic improvement in milk yield through selection of dams of cows was also low. It is argued from comparison with results from other parts of the tropics that superior genotypes for milk production are difficult to come by among indigenous cattle in these areas and that we should therefore look for other opportunities and methods to move ahead faster in the future.

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.

Time spent lying by lactating Holstein-Friesian cows of varying body condition scores (BCS) and milk yield was measured using an animal activity monitor. A 3-week average BCS was calculated for each cow; and in total, 84 cows were selected with 28 cows each among three BCS categories (Thin: BCS<2·75; Moderate: 2·75⩾BCS<3·25; Heavy: BCS⩾3·25) and two stage of lactation categories (<150 days in milk or >150 days in milk). Cows were kept in two management systems: parlour/freestall (n=60) or automated milking system/freestall (n=24). Behaviour was recorded for 5·3±0·1 d for each cow. Production levels were considered using a 28-d rolling average of daily milk production. Cows that exhibited clinical lameness before or during the observation period were excluded from analyses. For cows exhibiting oestrus, the day prior to, day of, and day following breeding were removed. The final analysis included 77 cows (408 d of observation). A mixed model was fitted to describe average daily hours spent lying. Results demonstrated that lying time increased as days in milk (DIM) increased (P=0·05). Variables that were tested but not significant (P>0·05) were BCS category, parity category (1 or ⩾2) and 28-d rolling average daily milk production. Although a numerical trend for increasing hours spent lying with increasing BCS was observed, after accounting for other factors in the mixed model, BCS did not significantly impact lying time. Continued investigation of these management factors that impact lying time and bouts, using new technologies, more cows, and more herds will help dairy owners better manage facilities and cow movements to optimize this essential behaviour.

Abstract Sheep farming plays a key role in the sustainability of the most depressed rural regions of Portugal, particularly in the Serra da Estrela region, and is recognized as an important source of income for many local farmers. Thus, the management of local sheep breeds in the region has over generations given rise to its most emblematic product: Serra da Estrela cheese, with Protected Designation of Origin (PDO). This study aims to briefly describe the sheep farms producing certified milk in the Serra da Estrela region. To this end, a survey form was drawn up and applied to 75 farms, randomly selected, from the defined geographical area of Serra da Estrela, from June to August 2020. The results show that the producers, mostly male, have an average age close to 51 years. On average, the herd size is equal to or greater than 100 animals and the daily milk production per animal varies between 0.47 and 1.0 L. The price of milk paid to the producer is, on average, at 1.25 Euros/L. Both the average herd size and the lactation length are higher than those described by others. The average daily milk production in most of these farms is in accordance with the standard average value related by other authors.
