The present study was to evaluate the reproductive and productive performance (RPP) of Indigenous (n=145) and Nili-Ravi cross-bred (n=55) dairy buffalo in relation to age, parity, body weight and body condition. A total of 200 buffalo cows were randomly selected and interviewed to collect data on reproductive and productive performance of buffalo cows of Rajshahi district by using pre-tested questionnaire during the period from January 2015 to December 2015. The average mean ± SD value of reproductive and productive performances were as age at puberty (AP), age at first calving (AFC), gestation length (GL), post-partum heat period (PPHP), milk yield per day (MYPD), lactation length (LL), birth weight of calf (BWC) and calving interval (CI) were recorded as 25.05±4.00 months, 35.26±4.14 months, 308.28±12.46 days, 84.00±25.95 days, 3.59±0.56 litre, 202.76±33.54 days, 28.79±4.23 kilogram and 461.36±15.41 days, respectively. Nili-Ravi cross-bred buffalo cow had shown better RPP than Indigenous. The genotype of buffalo cows had significant effect (p<0.05) on most of the RPP except AP, AFC and CI. Age of buffalo had also significant effect (p<0.05) on GL, PPHP and BWC and middle age (4 to < 7yrs) observed good RPP. The best RPP were recorded in 2nd parity than others and also significant effect (p<0.05) on GL, MYPD and BWC. Body weight and body condition of buffalo had significant effect (p<0.05) on PPHP, BWC and MYPD. The body weight of >350 kg and very good body condition groups were observed better reproductive performance. 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 systems. Very recently, a few farmers started farming of the mostly Indigenous buffalo cows for dairy purpose at Rajshahi region of Bangladesh. Asian J. Med. Biol. Res. September 2020, 6(3): 536-547

The study was conducted at Sylhet Govt. dairy farm to evaluate the productive and reproductive performance of Jersey× Frisian (J×F), Jersey × Local (J×L) and Sahiwal × Local (SL×L.) crossbred during the period of April 2007 to August 2009. Data on milk yield and different reproductive traits like lactation length, milk yield, length of dry period, service per conception, gestation length and post-partum heat period were evaluated. Results indicated that milk yield, length of dry period, service per conception and post-partum heat period were significantly affected (P<0.01) by different crossbred. However, lactation length and service per conception were significantly affected (P<0.01) by parity and interaction of breed × parity. The highest lactation length was observed for the genotype Jersey × Friesian (J×F) and the lowest was Jersey × Local (J×L) in the first and second lactation. The highest milk yield was observed for the genotype J×F and the lowest was J×L. The highest length of dry period was observed in SL× L and lowest was J×F. Furthermore maximum services were required for J×F. The highest gestation length was observed for genotype SL×L. The highest post-partum heat period was observed J×F. The overall reproductive performance of different crossbreds were varied.DOI: http://dx.doi.org/10.3329/pa.v22i1-2.16466 Progress. Agric. 22(1 & 2): 47 - 54, 2011

Although it has become increasingly clear that fertility in modern dairy cattle is declining in association with increased milk yields, the underlying mechanism is poorly understood. The first ovulation post partum is delayed in dairy cows undergoing selection for genetic merit for milk yield in association with lower circulating insulin concentrations. The aim of this study was to investigate whether feeding a diet to increase circulating insulin concentrations can overcome this delay in the first ovulation post partum. The experiment was a 2 x 2 factorial design (n = 10 per group) involving diet and genetic merit for milk yield. The dietary treatment started on the day of calving and lasted for 50 days. Plasma samples were collected each day and ovarian ultra-sonography was performed three times a week during the experimental feeding period. Milk yield was recorded each day, and body weight and body condition score were determined each week. Milk samples were collected three times a week from day 50 to day 105 post partum, and reproductive performance data were recorded for all the cows as part of the routine farm practice. The dietary treatment induced significant differences in plasma insulin concentrations in both high and low genetic merit cows. Although high genetic merit cows produced more milk, lost more body weight and had lower body condition scores during the experiment, no significant effect of diet was observed on these measurements. The high insulin inducing diet increased the proportion of cows ovulating within 50 days of calving and reduced the intervals from calving to first ovulation, and tended to reduce the intervals from calving to first service and to conception. These fertility parameters were also more favourable in low than in high genetic merit cows, but no interaction between diet and genetic merit was observed for any of these parameters. Genetic merit, but not diet, also affected the number of services required per conception and the conception rate. In conclusion, these results have confirmed that genetic selection for high milk yield is associated with a decrease in reproductive performance in dairy cows. More importantly, this study has demonstrated that it is possible to alleviate this problem by nutritional manipulation.

The growth rate, milk yield, milk composition and reproductive efficiency ofJamunapari goats were studied under semi-intensive conditions. Animals were allowedto graze for 6-7 hours and concentrate (17% CP, 11 MJ/kg DM) at 400g/head/day wasoffered twice daily. No body measurement was different in male and female goats. Theudder was capacious but pendulous. Testis length, breadth and scrotal circumferencewere 17.3 ± 1.5, 11.5 ± 1.7 and 42.4 ± 2.0 cm, respectively. The mean body weight at birthand at 12 months was 1.6 and 21.4 kg, respectively. The average growth rates of male andfemale kids were 59.4 and 48.2g/day, respectively. The overall rate of weight gain washighest in second month and lowest in 11th month. Highest milk yield was in secondmonth and lowest in the fifth month after kidding. Lactation length was 135.4 ± 14.9 and143.9 ± 13.2 days for does suckling one and two kids, respectively. Milk intake to growthratio was 15.6 ± 0.2 and 12.5 ± 0.3 for the litter size of one and two, respectively. Highestmilk fat, lactose and solids not fat (SNF) were in the later stage of lactation, whereasprotein and minerals were similar throughout the lactation. The average age at firstoestrus, age at first pregnancy and age at first kidding were 354.8 ± 17.1, 395.4 ± 29.6 and548.6 ± 68.1 days, respectively. The average number of services per pregnancy was 1.4.The gestation length was 152.8 ± 17.6 days. The average body weight just after kiddingand placenta weight were 26.7 kg and 342.4g, respectively. The overall litter size was 1.8and 32.9, 58.2 and 8.9% of kidding produced single, twins and triplets, respectively. Sexratio was 53.3 male to 46.7% female. Average onset of post-partum oestrus was 51 andinterval from parturition to pregnancy 69.3 days. Production of Jamunapari goats wascomparable with that of the Bengal goats.(Bangl. vet. 2010.

Effects of the body condition on the litter size, birth weight and kids survival of Red Sokoto goat were examined using seventy eight does aged 1-3 years. The does were flushed by grazing on cultivated pastures in the morning, and when indoor, they were served 500gm of concentrate ration per head per day. Their body conditions were assessed. All does used in this study fell within the body condition 1 with a mean body weight of 20.7kg and the body condition 2 with a mean weight of 24.1kg on a condition scale where 1 is poor and 2 is fair. They were randomly assigned to six sire groups and making lasted ten weeks. All does were reared as a group before and after parturition until the kids were weaned at 12 weeks. Does on condition score 2 significantly higher litter size (1.74) reared more kids to weaning (0.68) and were superior to does on condition score 1in overall productivity measured as number of kids weaned (89.21 vs 45.85%) or weight of kids weaned per doe kidding (4.92 vs 2.40kg). Does on the condition score 2 were twice condition score 1. The large difference in productivity would seem to justify investments in nutrition to breeding does prior to mating

The use of shearing during pregnancy has been described as a tool for improving productivity in sheep and for minimizing perinatal mortality in lambs through the increase of fetal development. This study assessed the effect of shearing around 74 days of gestation on the productive performance of ewes and lambs during the first month of life. Forty Corriedale ewes were inseminated in autumn in Southern Brazil. All ewes were kept together at the same pasture under extensive husbandry conditions. The ewes were randomly separated into two treatment groups: twenty animals were completely sheared at 74 ± 6 days of pregnancy, and twenty were kept without sheared during pregnancy, composing the control group. Ewes and their lambs were evaluated at three different times during the experiment: at birth, between 15 and 21 days post-partum and between 22 and 45 days post-partum. Ewes had their body condition score, body weight, placental weight, milk production and serum concentrations of beta-hydroxybutyrate measured, while lambs had hematocrit, hemoglobin, and plasma lactate and glucose, as well as body weight at birth and until wean determined. Values of hematocrit and hemoglobin were lower and body weight at birth and at wean was higher in the group of lambs born from sheared ewes. Placenta weight was higher in sheared ewes. Body condition score and beta-hydroxybutyrate showed no differences between groups. Milk production of sheared ewes (1.26 L/day) was higher than in control group (0.93 L/day). Shearing ewes at 74 days of pregnancy was efficient for the better development of lambs at post-birth, reducing perinatal mortality rates.

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.

The objective of the present study was to determine whether short-term calf removal (SCR) and/or bull exposure (BE) could improve post-partum reproductive performance. The trial was conducted during the spring and early summer when forage availability was optimum. Sixty-four Angus multiparous cows in good body condition were allotted according to a 2 × 2 factorial design involving SCR and BE. At 33 days post partum calves were removed for 72 h from the SCR and SCR + BE groups, and a vasectomized bull was introduced to the BE and SCR + BE groups and remained with the cows until the end of the experiment. Oestrous detection was performed daily based only on the homosexual behaviour of the cows. Cows were bred by natural service by two fertile bulls. Blood samples for progesterone analysis were collected alternatively every 3 and 4 days from 26 to 120 days post partum. There were no significant differences (P > 0·05) among groups in the ovulation, oestrus, and pregnancy rates during the breeding period, in conception rates, nor in the intervals from calving to first ovulation, to first oestrus, and to conception. Under the conditions of this experiment 72 h calf removal and/or bull exposure did not improve post-partum reproductive performance.

A comparative account of the productive and reproductive performance of crossbred and indigenous dairy cows at some selected areas of Comilla district. The survey was conducted on 50 dairy cows for a period of four months from June to September, 2004. Out of 50 cows 25 were crossbred and 25 were indigenous. Results showed that the average daily milk production of Local, Shahiwal x Local, Friesian x Local and Jersey x Local dairy cows was 2.26±0.19, 4.9±0.95, 6.0±1.0 and 5.71±0.87 liter respectively. The average age of calving interval and lactation length of the crossbred and indigenous cows did not differ significantly (P>0.05). However, the average age at puberty of Shahiwal x Local, Friesian x Local and Jersey x Local was significantly (P<0.01) lower than the local breed. The crossbred cows had significantly (P<0.01) lower pubertal age than local. The postpartum heat period and service per conception of different crossbred and local cows did not differ significantly (P>0.05). The average gestation length of Local, Shahiwal x Local, Friesian x Local and Jersey x Local was 289.88±1.44, 285.0±0.0, 285.0±4.18, and 282.08±2.42 days respectively. The productive and reproductive performance of Friesian x Local cows was superior to the rest of the breeds under study.
