Black Bengal Goat

The experiment was aimed to investigate and compare the growth, milk production and reproductive performances of Black Bengal goat under semi-intensive production (IP) and scavenging production (SP) system. Six Black Bengal does were assigned into 2 treatment (IP and SP) having 3 in each group. The IP group was allowed to graze six hours daily and supplemented with concentrate (soybean meal and wheat bran) and roughage (sorghum and common grass) and the SP group was maintained by the rural landless farmer traditionally as scavenging system. The average birth weight of kids were 1.30 and 0.96 kg for IP and SP systems, respectively and varied significantly (P<0.01). The birth weight of male kids were significantly (P<0.01) higher than that of the female kids. Pre-weaning gain was also significantly (P<0.01) higher in IP than sp system. In both the systems, male kids always showed higher gain than that of females. The kids were weaned at an average age of 92 and 81 days for IP and SP systems, respectively. The kids of the IP and SP systems attained at an average weaning weight of 5.43 and 4.17 kg, respectively which differs significantly (P<0.01). Weaning weight was found to be significantly higher in IP than SP systems. Average initial live weight, live weight at kidding and final live weight at post partum heat of does of IP and SP systems were 22.10, 22.61 and 21.03 and 21.90, 22.35 and 19.73 kg, respectively, where there was no significant difference except the final live weight (P<0.05). The average daily milk yield, total lactation yield and lactation length for IP and SP systems were 214 ml, 20.47 l and 95.33 days and 162 ml, 13.75 l and 84.66 days, respectively and varied significantly (P<0.01). Average litter size of the IP and SP systems was 2.00 and 2.33, respectively. Average post partum heat period and kid mortality were significantly (P<0.01) lower in IP than SP system. Gross return was found higher in IP than that of SP systems. Thus, it can be recommended from the present study that the growth rate, weaning age, weaning weight, milk production, post partum heat period and kid mortality of Black Bengal goat could be improved through proper feeding and better husbandry system which was reflected from gross return.

The present study was undertaken from January to June, 2014 to investigate the morphometric, productive and reproductive characteristics of Dwarf cattle available in Dinajpur District. The data obtained from 200 Dwarf cattle of different categories (yearling bull, adult bull, heifer, cow, male calf and female calf). A wide variety of coat colors among the cattle of the selected areas were found. The head length and width, ear length and width, horn length and diameter, neck length and width, body length at shoulder, wither height, heart girth, fore leg and hind leg length, tail length and diameter, teat length and diameter, distance between fore teats and rear teats, length and width of testis, weight of testis, live weight, daily milk yield, lactation length, gestation length, calving interval, dry period, post partum heat period, age at first heat and service per conception were recorded. The Dwarf cattle in Dinajpur District are comparatively smaller in size than most of the recognized breeds or types of cattle, however coat color showed remarkable variation. The data generated for Dwarf cattle in Dinajpur District would be useful to characterize them.Asian J. Med. Biol. Res. December 2015, 1(3): 380-386

Friesian Cows

The effect of time (morning or afternoon), intensity (three or four calves per cow), frequency Once or twice daily) and duration (1, 2, 4 or 8 weeks) of suckling on the performance of multiparous Friesian cows in early lactation was studied in four experiments. In each experiment there was a group of cows that were machine milked twice daily from calving. Milk production from sucked cows was greater during the suckling period than from machine-milked cows in the same period, but in no case was there any significant difference between suckling treatments. Increases in production during the 8-week suckling period ranged from 7.1 (P > 0.05) to 19.4% (P< 0.05), or from 75-21 8 kg. The extra milk produced by the cows sucked once daily went to the calves, and similar (P > 0.05) quantities or significantly less milk (P< 0.05) was produced at the alternate machine milkings compared with non-sucked cows in the same period. Regardless of suckling treatment in early lactation, the cows failed to show any carryover benefit. Lactation length and liveweight change in cows was unaffected by suckling treatment. The interval of post-partum anoestrus increased by about 6 days for each additional week of suckling. The average increase due to 8 weeks suckling in the four experiments ranged from 41-66 days. Teat damage increased with duration of twice-daily suckling, but had no effect on yields after sucking stopped. Teat damage of cows sucked once or twice daily to 8 weeks was similar. The incidence of mastitis was low in both sucked and machine-milked cows, and was not related to suckling treatment. Multiple sucking of Friesian cows in early lactation is a means of obtaining more milk from individual cows without incurring penalties in liveweight and body condition loss; it has no effect on post-weaning milk production.

SUMMARY1. The Awassi ewes reached an average live weight of 45 kg at two years of age and a mature weight of 57 kg at four years of age.2. The average yearly production of grease wool has been 2·2 kg.3. When rams were kept with the flock throughout the year approximately 60% of the lambings occurred during January–February. It declined rapidly during the following months and no lambs were born in July–August.4. Single lambs had an average birth weight of 4·6 kg for males and 4·3 for females. Twin lambs were about 20% lighter than singles. The corresponding weaning weight at two months of age was 17·9 and 16·8 for singles and 13·4 and 12·4 for twins.5. The twinning rate increased from 5% at first lambing to 30–35% at 6th lambing, when the ewes were about seven years old.

ABSTRACTThe effects of 18 buffalo sires, used in 2 years of a progeny-testing programme, on the subsequent lactation performances of their mates, were investigated from a study of 685 lactation records. The traits studied were: milk production, lactation length, length of post partum anoestrus, number of services per conception and length of service period (calving to conception). Parity of calving and sire had a significant effect on 305-day milk yield and lactation length of the mates. Between the 2 years, the sires did not differ for any of the traits of their mates. Although the breeding value of the sires, high or low, did not differ significantly, the sires with high breeding value tended to depress the milk production in the subsequent lactation of their mates and vice versa (r= −0·05). The birth weight of the calves significantly affected milk production. It was concluded that all methods of sire evaluation are likely to be biased by the effect of sires.

Black Bengal Goat

The present study was carried out to investigate the status of different reproductive parameters of Black Bengal in a rural area of Mukterpur under Charghat Upazilla of Rajshahi district during the period of July to December/2012. A total of 200 Black Bengal goats under both semi-intensive (n=100) and extensive condition (n=100) were selected on the basis of age, weight, body shape and conformation. The average age at puberty was 197.82±12.58 days and age at first conception was 292.96±0.50 days under semi-intensive condition whereas 208.82±12.60 days and 287.65±0.52 days under extensive condition. Age at first kidding was 448.26±25.48 days under semi-intensive condition whereas under extensive condition it was 450.07±22.43 days. Average litter size in the first, second and third parity was 1.06, 1.76 and 1.96, respectively under semi-intensive condition whereas under extensive condition, these were 1.01, 1.76 and 1.96, respectively. The average kidding interval of goats under semi-intensive and extensive conditions were 190.2±20 and 178.23±.50 days, respectively and the difference between these two was statistically significant (p<0.01). Sex ratio of male and female kids born was found to be 56 : 44, 44 : 56 and 55 : 45 in the first, second and third parity, respectively under semi-intensive condition whereas, it was 55 : 45, 48 : 52 and 54 : 56 in the first, second and third parity, respectively under extensive condition. The usual numbers of kids at one time in Black Bengal goats varied from single to quadruplet. Average post partum weight of does was higher under semi-intensive condition than extensive condition which was statistically significant (p<0.05). Age of kid mortality was more in first parity under one month of age but gradually decreased with the age of kids under both semi-intensive condition and extensive condition. The average birth weight of kids was 1.28 ± 0.11 kg and 1.25 ± 0.10 kg under semi-intensive and extensive condition respectively which was statistically significant (p<0.01). Average birth weight of male was higher than female under both conditions. Kid mortality increased from 2 to 21% with the increase of parity. Birth weight of kids was higher in July-October and kid mortality was higher in winter season. The age at puberty was found earlier in summer season than others seasons under both semi-intensive and extensive conditions. Reproductive performances of Black Bengal goat were better in third parity than that of the first and second parity under both conditions.Asian J. Med. Biol. Res. June 2015, 1(1): 22-30

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 Adequacy of milk production in the newborns will affect the success of exclusive breastfeeding. Not all postpartum mothers are able to increase milk production in the postpartum period. Acupressure at the meridian points is one way to increase milk production in postpartum mothers. This study aims to determine the effect of acupressure therapy on increasing breast milk production in postpartum mothers at PKU Muhamadiyah Bantul. This study was a quantitative study  a quasi-experimental research design with pre-test and post-test nonequivalent control group. The number of respondents in each group was 17 people. The treatment given was acupressure at the meridian points for 5 minutes on days 2 and 3of poatpartum. Breastfeeding adequacy was assessed before treatment and on day 4 postpartum. Data were analyzed by Mc Nemar analysis. The results showed that there was a significant difference in breast milk production before and after acupressure with p value of 0.000 (p value <0.05). There was a significant difference in breast milk production in the control group before and after being given the breastfeeding technique leaflet p value 0.001 (p value <0.05). Conclusion: There is no significant difference in breast milk production after being given acupressure and after being given leaflets about breastfeeding techniques at PKU Muhamadiyah Bantul p value 0.100 (p value> 0.05).  Keywords: acupressure, breast milk production, postpartum

Holstein Calves

The present study was conducted to determine some environmental factors affecting birth weight, weaning weight and daily live weight gain of Holstein calves of a livestock facility in Izmir, Turkey. The data on 2091 calves born between the years 2005-2010 were used to assess the relevant parameters. Effects of calving year, calving month, calf gender and the interaction between calving year and calving month on calves’ birth weights were highly significant. The overall mean of birth weights was 39.6±0.15 kg. In addition, effects of calving year, calving month, gender, birth weight, weaning age, calving year x calving month, calving year x gender and calving year x calving month x gender interactions on weaning weight (WW) and daily live weight gain (DLWG) were highly significant. The overall means of WW and DLWG were respectively found to be 79.7±0.20 kg and 525±2.5 g. A one kilogram increase in birth weight resulted in an increase of 0.89 kg in weaning weight and a decrease of 1.26 g in daily live weight gain. Prenatal temperature-humidity index (THI) affected birth weight of calves (R2=0.67). Increasing THI from 50 to 80 resulted in 3.8 kg decrease in birth weight.

The aims of this study were to evaluate the traits of reproductive, milking and growth performance of Saanen and Saanen × Hair crossbreds (F1, B1 and B2) raised at the Bandırma Sheep Research Institute. The data were collected from 868 goats for reproductive performance and milk yield and from 1077 kids for survival performance between 2009-2012. Milk components (fat, protein, lactose and non-fat dry matter) of goats (n=162) and body weight changes of kid’s (n=64) were evaluated for one year in 2012. Estrus rates and survival rates were similar among all genotypes. Kidding rate was significantly higher in F1 goats than Saanen goats. Saanen goat had the lowest average mean daily milk yield compared with other genotypes. The effect of year and age were significant on milk yield. Goats in F1 and B1 genotypes had higher milk protein percentage and non-fat dry matter content in comparison with Saanen and B2 genotype. Milk fat and lactose contents were similar among genotypes. Birth weight and monthly live weight were similar between genotypes while weaning weight, six month live weight and yearling live weight were higher in B1 kids in comparison with Saanen kids. The effect of dam age and birth type were significant on birth weight, monthly live weight and weaning weight. The findings related to performance characteristics in goat genotypes investigated show that B1 genotype could be recommend for semi-intensive production system in the Western Anatolia.

The paper presents the results of studies of milk productivity of black-and-white cows depending on the age of the first insemination and live weight at the first calving in the conditions of the Irkutsk region. The dynamics of heifer rearing by year, milk productivity of cows in the 1st and 3rd lactations depending on the intensity of their development has been studied. The experiment was conducted on farm materials from the Irkutsk Region using generally accepted zootechnical, analytical, variation and statistical research methods from 2016 to 2020. Live weight of heifers at all ages met the requirements of the elite and elite-record classes. Analysis of the data showed that the growth rate of the animals increased during 5 years (6.0%, 6.8, 2.3 and 4.8% respectively with a significant difference p ≥ 0.90). With the increased intensity of heifer rearing, an increase in milk yield over 305 days of the first lactation was observed. The highest milk production was noted in the 1st (5309-5476 kg) and 3rd (5418-5817 kg) lactations in cows with the first fruitful insemination at 13-14 months. The lowest 1st and 3rd lactation yields are obtained from cows inseminated at 20 months of age or older. Higher milk production in the first and third lactations was obtained from cows with a live weight at first calving of 541-550 kg, 551 kg and higher (5197-5164, 5436-5545 kg respectively). Less milk production was obtained from cows with a live weight at first calving of up to 500 kg (4567-5122, 4943-5009 kg). The results obtained make it possible to reveal the influence of the intensity of rearing heifers on the productive qualities of cows.
