The prevalence of claw affections was investigated in 602 cattle in two organized dairy farms during June 2010 to May 2011. Of these cattle 176 were from Bangladesh Agricultural University Dairy Farm (BAUDF) and 426 were from Central Cattle Breeding Station and Dairy Farm (CCBSDF). These animals were studied under 6 groups: calf, heifer, pregnant cow, lactating cow, dry cow and breeding bull. Out of 426 cattle in CCBSDF, 85 animals were affected with various claw affections, the prevalence being 19.95%. The prevalence in BAUDF was 22.72%. Claw affections causing lameness comprised sole ulcer (3.82%), heel erosion (2.49%), interdigital necrobacillosis (2.15%), sand crack (1.82%), hoof overgrowth (3.32%) and white line disease (2.32%). The prevalence of lameness in BAUDF was 13.06% and that in CCBSDF was 11.50%. Sole ulcer (3.82%) was predominantly associated with lameness in both farms while the lowest prevalence of lameness was encountered with interdigital dermatitis (1.39%). The lowest prevalence of lameness was observed in calves in both BAUDF (0.56%) and CCBSDF (0.93%). Pregnant cows were the most vulnerable to claw diseases and manifested lameness of varying degrees. Hind limbs were more frequently affected with claw affections than fore limbs. Animals of over 5 years were mostly affected with foot diseases. Breeding bulls showed 2.27% prevalence of lameness in BAUDF and 1.87% CCBSDF. Among various affections sole ulcer ranked the highest in both the farms. Sand crack and interdigital necrobacillosis registered the lowest prevalence in BAUDF and interdigital dermatitis was the lowest in CCBSDF. Sole ulcer ranked the highest among all claw affections. Pregnant cow were more vulnerable to lameness. Hind limbs were frequently affected with various lesions than the forelimbs.Res. Agric. Livest. Fish.4(3): 193-199, December 2017

High Prevalence

A total of 560 lactating cows belonging to Bangladesh Agricultural University dairy farm (n = 59): Local Zebu (L), Local × Friesian (L × F), Local × Jersey (L × J), Local × Red Chittagong Cattle (L × RCC), Local × Sahiwal (L × SL), Red Chittagong Cattle (RCC); and Central Cattle Breeding Station and Dairy Farm (n = 501): Local Zebu, L × F, SL × F, Sahiwal and Australian Friesian Sahiwal (AFS) were selected to measure prevalence of subclinical mastitis (SM). The California Mastitis Test was done and the prevalence of SM was 68% on cow basis and 57% on quarter basis. The prevalence rate was significantly higher in L × F (87%, P < 0.05), SL × F (88%, P < 0.05), L × J (100%, P < 0.01), AFS (89%, P< 0.05) and SL (100%, P < 0.01). The local Zebu (31%) and RCC (28%) were least susceptible to SM. SM was significantly higher in multiparous (P < 0.05) and older cows (P < 0.05). The front quarters were more prone to SM than the rear. Factors such as breed, age, parity and management may have been responsible for high prevalence of SM in both farms.

The study was conducted on 244 crossbred cows of CCBS Savar, Dhaka to evaluate the effect of different genetic groups on their lifetime performance of various reproductive traits using twenty years data. Data were accumulated from a prescribed data sheet maintained by Central Cattle Breeding Station, Dhaka. Genetic groups for this experiment were (LF), (LJ), (LH x F), (LF x LF) and (LJ x LJ). The studied parameters were age at puberty, service per conception, post-partum heat period, calving interval, total number of calving in lifetime. ANOVA showed that genetic groups had a significant effect on age at puberty, post-partum heat period, total number of calving in lifetime and calving interval (P<0.05). From result it was found that earliest age at puberty were in L x F (749.27±99.01), service per conception, postpartum heat period was lower in L x F (1.60±0.19 and (145.75±94.44 days respectively). Calving interval was lower in L x J (411.18±136.87 days) and almost similar results were obtained for L x F (432.26±96.26 days). Total number of calving in lifetime were observed higher in (LH x F) with mean of 1468.30±198.58 days.J. Environ. Sci. & Natural Resources, 10(2): 87-94 2017

Impacts of age, body weight, body conditions, and scrotal circumference on sperm abnormalities of bulls used for artificial insemination (AI) in Bangladesh have been studied. During 1997-2002, 1390 ejaculates of semen from 71 bulls from Central Cattle Breeding Station and Dairy Farm, Savar, Dhaka, Rajshahi Dairy and Cattle Improvement Farm, Rajabarihat, and District Artificial Insemination Centre, Rajshahi, were collected and examined. Total head abnormalities, free loose head, mid-piece, tail abnormalities, proximal and distal cytoplamic droplets, total tail abnormalities and total sperm abnormalities were recorded. Age of the bulls had significant effect on sperm abnormalities (P < 0.01) except for proximal cytoplasmic droplet. Similarly, body weight had significant effect (P < 0.05) except for the total head abnormalities, while body conditions had no significant effect on mid-piece, total tail abnormalities and total sperm abnormalities except for the total head abnormalities. Scrotal circumference had significant effect (P < 0.05) on all the sperm abnormalities. The present results demonstrate that the middle (8 to < 10 yrs) and older (>10 yrs) bulls having body weight of < 450 kg, very good body condition and 36 to < 38 cm scrotal circumference had the lowest sperm abnormalities. The need for semen examination for morphological abnormalities of spermatozoa in bulls to be used for AI programme is strongly implicated by this study.

Abstract The studies were performed in the dairy farm from Dancu Research and Development Station for Cattle Breeding, Iaşi, Romania, for a period of 5 consecutive years (2007- 2011), an effective annual rolled of 450 cows Bălţată cu Negru Românească (Romanian Black Spotted) breed.The experimental groups were composed of cows with anoestrus in 60 days postpartum interval, diagnosed by rectal examination with various ovarian disorders: persistent corpus luteum - group E1-162 cows and luteal cysts- group E2-138 cows. The treatments according to diagnosis were applied: PGF2α-,500 mcg/cow- group E1 and Gn-RH, (Receptal, 5 ml/cow-group E2). In relation to the year in which treatments were applied some variations in reproduction indices were found. Regarding to average intervals from treatment to first insemination and from treatment to conception respectively, significant differences were not found. Regarding to average conception rates after treatments, significant differences were found: in E1group, conception rate at the first insemination was 30,9% (with annual variations between 15,0% in 2008 and 41,1% in 2009) (p<0,01); per total insemination was 64,42 % (with annual variations between 44,7% - 2011 and 76,9% - 2007) (p<0,001) and pregnancy index was of 2,4 (with annual variations between 1,9 - 2009 and 2,8 - 2008); in E2 group, conception rate to first insemination was 25,96% (with annual variations between 16,66% - 2011 and 40% - 2010) (p<0,01); per total insemination was 77,88% (with annual variation between 52,17% - 2008 and 85,0% - 2010) (p<0,001) and pregnancy index of 2,4 (with annual variations between 2,1 - 2007 and 2,6 - 2008 and 2009). In relation to season in which treatments were applied, we found different variations in conception rates: in group E1, the average conception rates at the first insemination were between 24,24 % (autumn) and 40,7% (summer) (p<0,05) and per total inseminations between 75,0% (spring) and 85,71% (autumn) (p<0,05); in group E2, the average conception rates at the first insemination were between 5,3% (summer) and 48,5% (spring) (p<0,001) and per total inseminations between 68,4% (summer) and 81,8% (spring) (p<0,05). We believe that annual and seasonal variations found in this work are due to some deficiencies of management system in dairy farms, such as the stalls prolonged maintenance and lack of active movement in the cold season, inadequate microclimate of shelters, heat stress and deficiencies in cows feeding , especially those with higher milk production.

Prevalence of lameness was investigated in 1000 randomly selected cattle in Veterinary Teaching Hospital, Bangladesh Agricultural University (BAU) and different dairy farms in Boira Union, Mymensingh during January to December 2015. The aetiology, age [Cal≤f 1 year, 1 - 3 years, 3 - 5 years and >5 years], sex (male, female), different stages of cattle [Calves, Heifers, Pregnant cows, Lactating cows, Dry cows, and Bulls] and floor type (concrete, muddy floor, pavement, straw yard) were studied. Out of 1000 cattle examined, 111 (11.1%) showed lameness in different grades, with 82.0% slightly, 14.4% moderately and 3.6% severely lame. The aetiologies of lameness are upward fixation of patella, traumatic injury, foot and mouth disease (FMD) complications, arthritis, interdigital hyperplasia, interdigital dermatitis and interdigital necrobacillosis. Higher percentages of lameness were in hind limbs than fore limbs. Left hind limbs were more frequently affected than right hind limbs. Animals over 5 years of age were most vulnerable to lameness. Female especially high yielding cows were at higher risk (69.4%) than the male cattle (30.6%). Prevalence of lameness was higher when cattle were confided to the concrete floor than the muddy floor. Pregnant cows were the most vulnerable to lameness. It is suggested that aetiology, age, sex, different stages of cattle and floor type could be considered as risk factors causing lameness in cattle.Bangl. vet. 2017. Vol. 34, No. 1, 1-8

The Republic

The effectiveness of dairy cattle breeding largely depends on the intensity of use of the breeding stock. At the same time, the factor of the duration of economic use of animals is gaining importance, which affects not only the production economy, but also the improvement of stocks and breeds. The lifelong productivity, the quantitative and qualitative growth of the stock, the amount of capital investment in its formation and the efficiency of operation depend on the term for the productive use of cows. The terms of breeding and production use of animals are direct linked with the biologically possible longevity of each animal, in turn, the duration of the productive period of cattle is in the range of 12-17 lactations. The influence of feed on production is associated primarily with the level of digestion and assimilation. The digestive capacity of the digestive tract of animals can be improved by selecting the optimal ratio in the diet of rough, juicy and concentrated feeds, i.e. optimization of animal feeding types. We conducted an analysis of milk productivity in lactating cows, when using AVMC feed additive in the diet. The experiment was conducted in the conditions of the dairy farm of Biryuli CJSC of the Vysokogorsky District of the Republic of Tatarstan on three groups of lactating cows. For the experiment, 30 cows were selected, 10 in each Holstein black-and-white breed according to the principle of analogues. Studies have shown that AVMC with rapeseed oil seeds and AVMC with fus in the diet of lactating cows provided higher animal productivity and positively affected the chemical composition of milk.

The purpose of this study is to compare innovative technology usage levels of dairy farms, supported and non-supported by The Instrument for Pre-accession Assistance-Rural Development (IPARD) program, by scoring their usage level of 10 innovative technologies in their dairy farms. Another purpose of the study is to determine the factors associated with the innovative technology usage levels of dairy farms. The main material of the study is dairy farms supported and not supported by the IPARD program in Konya. Full count sampling method was used when determining the dairy farms supported by IPARD Program and Neyman allocation sampling method was used when determining the dairy farm non-supported by IPARD program. Research data were collected from 50 dairy farms supported by IPARD program and 100 dairy farms non-supported by IPARD program by administering a questionnaire filled during the face-to-face interviews conducted with each individual respondent. As a result of the study, it was determined that the average gross production values and gross profits of dairy farms supported by IPARD program were 4 times higher than those non-supported by IPARD program. While innovative technology usage level of dairy farms non-supported by IPARD program were entirely low level, 90% of dairy farms supported by IPARD program were high level. From the point of view of dairy farm scale, it was determined that innovative technology usage levels were high (69.84%) in dairy farms that had 51 and more milking cows. As a result of chi-square independence test, statistically significant relationship was found between innovative technology usage level of dairy farm and 12 of 13 factors.

The study was conducted on 244 crossbred cows of (Central Cattle Breeding and Diry Farm), Savar, Dhaka to evaluate the effect of different productive groups on their lifetime performance of various productive traits using twenty years data.  Data were accumulated from a prescribed data sheet maintained by Central Cattle Breeding Station, Savar, Dhaka. Genetic groups for this experiment were Local Friesian (LF), Local Jersey (LJ), Local Hariana X Friesian (LH x F), Local Friesian X Local Friesian (LF x LF) and Local Jersey X Local Jersey (LJ x LJ). The studied parameters were age at puberty, lactation length, lactation yield, total milking days, and total milk yield in lifetime. The data were analyzed using Least-Squares Mixed Model and Maximum Likelihood Computer Program (Harvey, 1990). Analysis showed that genetic groups had a significant effect on age at puberty, lactation length and lactation yield (P<0.01), total milking days and milk yield in lifetime (P<0.001). From the result it was found that earliest age at puberty were in L x F (749.27±99.01). Lactation length and standardized lactation yield were also higher in L x F (258.69±20.04 days and 1408.80±83.60 kg respectively). Total milking days and milk yield were observed higher in (LH x F) with mean of 1468.30±198.58 days and 7340.32±1813.28 kg, respectively. The repeatability estimates of lactation length for genetic groups LF, LJ, LH x F, LF x LF and LJ x LJ were 0.24±0.09, 0.04(-ve), 0.10±0.05, 0.07±0.05 and 0.49±0.22, respectively. The same for lactation yield was 0.17±0.08, 0.27± 0.02, 0.07±0.04, 0.17±0.08 and 0.03±0.05 respectively. From analysis it was revealed that in respect of productive performances the L x F genetic group was found superior compared to other groups but interns of total lifetime productivity, LH x F ranked the highest in the given environment. It is concluded that lifetime productivity needs to be considered as an appropriate guideline for selecting genetic groups for future productivity.Progressive Agriculture 29 (2): 168-177, 2018

Handling systems can influence the production of biogas and methane from dairy farm manures. A comparative work performed in three different Italian dairy farms showed how the most common techniques (scraper, slatted floor, flushing) can change the characteristics of collected manure. Scraper appears to be the most <em>neutral</em> choice, as it does not significantly affect the original characteristics of manure. Slatted floor produces a manure that has a lower methane potential in comparison with scraper, due to: a lower content of volatile solids caused by the biodegradation occurring in the deep pit, and a lower specific biogas production caused by the change in the characteristics of organic matter. Flushing can produce three different fluxes: diluted flushed manure, solid separated manure and liquid separated manure. The diluted fraction appears to be unsuitable for conventional anaerobic digestion in completely stirred reactors (CSTR), since its content of organic matter is too low to be worthwhile. The liquid separated fraction could represent an interesting material, as it appears to accumulate the most biodegradable organic fraction, but not as primary substrate in CSTR as the organic matter concentration is too low. Finally, the solid-liquid separation process tends to accumulate inert matter in the solid separated fraction and, therefore, its specific methane production is low.
