SUMMARYReproductive and production traits were studied in a crossbreeding experiment involving Red Danish cattle, Indian milch breeds and native Zebu cattle in various combinations.Frequency of abortions and postnatal mortality were higher for Red Danish than for Indian milch breeds and crossbreds, age at first calving was higher for Indian milch breeds than for other groups, calving interval was longer for purebreds than for crossbreds. Milk and butterfat production in first and second lactation increased with increasing proportion of genes from Red Danish cattle. The range of milk production in first lactation was from 987 kg for Indian milch breeds to 3445 kg for Red Danish imported from Denmark.The optimum proportion of genes from Red Danish for the environmental conditions prevailing in the present crossbreeding experiment is considered to be 60 to 80%.

Factors Affecting

A cross sectional study was conducted to observe the factors affecting the productive performance of dairy cattle from northern rural areas of Bangladesh during July and September 2013. Data of 105 cows, 85 (80.95%) from local and 20 (19.05%) cows from cross breed, were randomly selected for the study. A binary logistic regression, expressed by odds ratio with 95% confidence interval, was done to determine the association of daily milk production categorized into ? 2 and > 2 liters (L), based on median, with the significant explanatory variables of body weight, age at first calving, lactation period, vitamin use, type of floor and milking person. The result demonstrated that the probability of milk production of >2 L was 6.16, 4.5, 20.65 and 5.7 times higher from the with animal body weight of >140 kg, age at first calving of >36 m, lactation period of >8 m and vitamin use than that of body weight of 140 kg, age at first calving of ?36 m, lactation period of ? 8 m, and not vitamin used respectively. The chance of milk production of > 2 L was 0.25 and 0.22 times lower for mud floor, and owner milking than that of brick floor and gowala (professional milking person) respectively.

Background: Productive and reproductive performances are the most important parameters in the Ehiopian dairy sector. The objective of the current study was to assess milk yield, reproductive performances of crossbred dairy cattle and occurrence of reproductive health problems and veterinary services provider/s. Methods: A cross-sectional study using semi-structured questionnaire was used to collect information from 160 randomly selected dairy farm owners found in urban and peri-urban areas of Assela, Bishoftu, Holetta and Sululta of the central highlands of Ethiopia. Result: The higher average daily milk yields were 11.7 and 11.2 litres in urban and peri-urban Bishoftu. The average age at first service of crossbred dairy heifers was 18.8 months in urban and 19.1 months in peri-urban Bishoftu, respectively. The average age at first calving of crossbred dairy heifers was 27.8 months in urban Bishoftu and 28.1 months in peri-urban Bishoftu areas. The longest average age at first service (29.3 months) and age at first calving (38.3 months) were in peri-urban Assela. The number of services per conception was 1.4 in urban Assela and 1.3 in peri-urban Assela and these were shorter than the 1.65 from urban Bishoftu and the 1.85 of peri-urban Bishoftu areas. The average 168.0 days calving to conception interval from peri-urban Assela was the longest calving to conception interval in this study. The average calving intervals 14.9 and 13.9 months of peri-urban Assela and Sululta were relatively longer than the respective urban areas.

Abstract: This study aimed  to evaluate the effect of lactation on first follicular wave surge of crossbred (Gir x Holstein) dairy cattle.  Nine multiparous crossbred dairy cattle were divided according to daily milk production (Group 1 = milk production higher than average, n = 5; Group 2 = milk  production  lower  than  average,  n  =  4).  From  calving  (Day  0)  until  divergence  of  first follicular wave, ovaries  was monitored daily by ultrasound exams to observed the follicular emergence,  growth  rate,  maximum  follicular  diameter,  day  of  follicular  divergence  and ovulation. The mean of milk production was 17.4 + 6.4 L/day (n= 9). Group 1 had higher daily milk production than Group 2 (21.8 + 3.8 L/day vs. 11.9 + 3.9 L/day, P< 0.001). Data of follicular emergence were similar in both groups (P >0.05). The growth  rate of first follicular surge was higher  in  Group  2  than  Group  1  (2.0  + 0.0  mm/day  vs  1.2  + 0.6  mm/day,  P<  0.05).  The maximum follicular diameter was 11.6  + 0.9 mm (Group 1) and 13.5  + 1.7 mm (Group 2); P< 0.05. The follicular divergence occurred earlier  in Group 1 than Group 2 (12.2  + 0.8 days vs 13.7 + 0.6 days; P< 0.05). One animal of Group 2 ovulated. In conclusion, data suggested that milk production had influence on ovarian follicular dynamic after calving.Keywords: Follicle, post-partum, lactation, dairy cattle

Potential Factors

To evaluate milk production performance in stall feeding dairy cattle in relation to associated biological factors such as age of cow, age of first calving, breed and number of parity at Central Cattle Breeding Station, Savar, Dhaka, a cross sectional study was performed on April, 2002 using a structured questionnaire. Local (21%), pure bred "Sahiwal" (12%) and cross bred (L×F1; L×F2; L×F3; SL×F2>) (67%) were the breed of studied cows (n = 62). The average age and milk production of the cow was 94.9 months and 3.9 liter/cow/day. The parity number and age at first calving of a cow were recorded to be average 4 and 43 months respectively. The younger cows (≤99 months) were 6.7 time more likely to have yielded >3 liters/cow/day than the older cows (>99 months) (p < 0.001). Cows with ≤4 parities were recorded to have 7.6 times more chance to produce milk of >3 liters/cow/day than cows with ≥4 parities (10.9%) (p < 0.001)). The milk production of >3 liters/cow/day is 39.3 times higher in the crossbred than the milk production in the local breed (p < 0.001).
