Small Scale Dairy

Management and production characteristics impact conception rate to first service (CR1S) in small-scale dairy farms, but the impact of body condition score (BCS) and milk production levels on cows’ fertility is unknown. Our objective is to determine the effect of BCS and milk production on CR1S in small-scale dairy farms of western Mexico. Logistic regression models are used to determine the effect of BCS (at calving and first service), 60-d and 305-d milk production, protein and fat production, lactation number, and days at first service on CR1S. BCS at calving does not affect CR1S in cows with three or more lactations (39.5%; p > 0.1). However, first-lactation cows with BCS < 3.0 at calving and second lactation cows with BCS ≤ 2.5 at calving have higher CR1S (63.2 and 67.9%, respectively; p < 0.1). This result is perhaps due to reduced milk production, which leads to lower metabolic stress. BCS ≤ 2.5 at calving is associated (p < 0.05) with a reduced milk yield, explaining partially the observed higher CR1S in these groups. Cows with BCS ≤ 2.5 at first service in the higher quartile of 60-d milk production (≥ 28kg/day) show lower CR1S (23.9 and 51.1%, respectively; p < 0.01). In conclusion, BCS at calving and at first service, 60-d milk production, and lactation number are factors associated with CR1S.

A total of 94 blood samples were collected from commercial dairy farms, from 6 Upazillas of Barisal division. The prevalence of Bovine Viral Diarrhoea Virus (BVDV) in south Bengal areas was 51.1%, the maximum prevalence was in Ujirpur Upazilla (Sub-district; 100%) and the lowest in Pirojpur Upazilla (13.6%). There was significant (P<0.05) variation in the prevalence between farms. Prevalence was highest (61.3%) in animals between 3 and 5 years of age, and lowest (31.8%) in 0-1 year-old animals. Animals with low body condition score (BCS-2) had higher (63.6%) prevalence in comparison to animals of high BCS-3.5. Haemoglobin (Hb) was 8.7 ± 0.1 gm% compared to 8.6 ± 0.1 gm%. Lymphocyte count was significantly (P<0.05) higher (64.1 ± 0.3%) in BVD-positive animals than negative animals (41.8 ± 1.2%). The neutrophil count was significantly (P<0.05) higher in BVD-positive animals (22.1 ± 0.5%) compared to negative animals (16.9 ± 0.5%). Other haematological parameters were not significantly different.Bangl. vet. 2015. Vol. 32, No. 2, 48-54

And Performance

The present study was conducted in 33 dairy farms to evaluate the welfare quality of Australian-zebu cross bred cows through some animal-based welfare indicators. The main aims of this research were to identify welfare issues facing dairy cows and investigate whether indicators are associated with measures of welfare and performance efficiency. The assessment of animal welfare was performed (330 animals) Australian-cross breed in family dairy farms at Sirajganj district of Bangladesh. Data were collected through face-to-face interview with farmers, followed by an inspection and observation of dairy cows. A total 330 females (43 heifers and 287 cows) were included in this study. Body condition, body cleanliness, injury, lameness, health status and milk yield were assessed. Among studied animals, body condition score 2 about (65.5%), hock joint injury (83.6%), knee injury (48.8%), and a pronounced state of poor cleanliness on: dirty udder (55.9%), flank (55.0%) and hind limbs (96.4%) were observed. Health status including diarrhea, respiratory distress, coughing, nasal and ocular discharge were present in some animals. The results indicate that very good BCS and mastitis free cows are related to higher milk yields. Results of this study may indicate the some indicators that influence the animal welfare and productivity in selected farms. As this work was a preliminary study, so the comprehensive research is needed to further develop the prototype protocol.Res. Agric., Livest. Fish.3(3): 417-424, December 2016

AbstractThe associations between occurrence of diseases, milk yield, and body condition score on conception risk after first artificial insemination were analysed in an observational study of 43 farms participating in a herd health program. Data were taken from 9369 lactations, from 4382 cows inseminated between 20 and 180 days in milk in the period 1990 to 1996. Two logistic regression models, one containing data from all lactations and a subset containing data from 1762 lactations with body condition scoring were used to determine pregnancy risk at first AI. A 1-point loss in body condition score during the 100 days after calving resulted in a 20 percent reduction in the risk of conception. Relative within herd kg milk yield had a significant and linear negative association with fertility. Increases and decreases in the percentage milk fat (or milk fat to protein ratios) from the monthly test days near to AI date are significantly (P < 0.01) predictive of AI outcome. Metritis, cystic ovarian disease, lameness, and mastitis gave odds ratios of for pregnancy risk ranging from 0.35 to 1.15, largely dependent on the interval in days from final disease occurrence to first AI. The advantages of coding diseases for linear or non-linear time-dependency were examined. Other diseases with significant effects associations to pregnancy risk were displaced abomasum, milk fever and retained foetal membranes. These diseases showed little relationship between fertility and the number of days since last occurrence. Results of this study confirm the negative effects of milk yield, body score condition loss, and disease on dairy cow fertility. The effects of some diseases on first service conception are strongly dependent on the interval since last disease occurrence. This is especially valid for clinical mastitis which has an extremely weak effect on conception if occurring prior to AI and is associated with > 50 percent reduction in pregnancy risk if occurring in the 3 wk period directly after AI.

AbstractIn this Research Communication we analyse the animal welfare status of dairy farms located in southern Spain and test the hypothesis that monitoring of wellbeing could increase the profitability of dairy herds by improving indices of reproduction. Twenty dairy farms were visited and a total of 1650 cows were assessed using the Welfare Quality® (WQ) protocol to determine their welfare status. These farms were selected as representatives of the main types of dairy farms found in the south of Spain. No farms attained a welfare status of ‘excellent’, but all obtained an adequate score for most parameters. Feeding assessment showed relatively low variability among farms, whereas housing and health assessments exhibited high variability. Significant correlations were found between a number of welfare parameter pairings: between percentage of collisions and time needed to lie down; between cleanliness of water points and cleanliness of various animal parts; between farms with access to an outdoor loafing area and an inadequate body condition score and with animal cleanliness; between the frequency of animals lying partly or completely outside of the lying area and the percentage of integument alterations and finally between the presence of respiratory problems and farm hygiene parameters. Furthermore, significant correlations between welfare parameters, reproductive indices and milk production were found. The percentage of cows exhibiting an inadequate body condition score and farms where cows took longer to lie down were correlated with the calving-first insemination interval. Animals showing a higher incidence of coughing and hampered respiration presented lower heat detection rates and milk production and finally farms with dirtier animals had lower milk production. This study is the first step towards including welfare in the recording of routine data in dairy cattle farms in southern Spain.

Zusammenfassung Ziel der Studie war, den Energiebedarf von Warmblutfohlen zu überprüfen, die durch einen Betriebswechsel beim Absetzen erhöhtem Stress ausgesetzt sind. Material und Methoden: Neun Hengstfohlen, die als Absetzer von verschiedenen Züchtern gekauft und gemeinsam aufgestallt wurden, nahmen an der Studie vom Absetzen im Alter von etwa 6 Monaten bis zu einem Alter von etwa 1 Jahr teil. Das Absetzen erfolgte im heimischen Betrieb oder nach gemeinsamem Transport von Stute und Fohlen bei Ankunft im neuen Bestand. Die Fohlen erhielten Heulage (später erster Schnitt), Hafer und Fohlenaufzuchtfutter. Um eine individuelle Kraftfutterzuteilung zu ermöglichen, wurden die Fohlen zweimal täglich separat angebunden. Erhoben wurden die Gesamtaufnahme der Heulage aller Fohlen gemeinsam pro Tag, die tägliche individuelle Kraftfutteraufnahme sowie in 4-wöchigen Abständen Körpermasse und Body Condition Score (BCS). Ergebnisse: Die tägliche Energieaufnahme der Fohlen betrug 74 MJ verdauliche Energie (68 MJ umsetzbare Energie) pro Tier. Die Fohlen wurden mit vergleichsweise niedrigem BCS von 4,2 ± 0,4 (Skala von 1 bis 9) und einer durchschnittlichen Körpermasse von 285 ± 30 kg aufgestallt. Sie erreichten am Ende der Studie im Alter von 319 ± 22 Tagen eine Körpermasse von 326 ± 24 kg und einen BCS von 4,2 ± 0,4. Die Energieaufnahme der Fohlen war höher und ihre Gewichtsentwicklung langsamer als in einer parallel laufenden Studie mit Fohlen, die im Gestüt geboren und aufgewachsen und dementsprechend beim Absetzen weniger Stress ausgesetzt waren. Schlussfolgerung und klinische Relevanz: Fohlen mit relativ niedriger Körpermasse und BCS und erheblichem Stress zum Zeitpunkt des Absetzens benötigen deutlich mehr Energie als Fohlen, die beim Absetzen in ihrer gewohnten Umgebung verbleiben und dadurch weniger Stressoren unterliegen.
