AbstractLimited information is available about the actual management characteristics of dairy donkeys in Southern Europe. The aim of the present study is to describe animal management of dairy donkey farms in Italy. Twelve farmers were asked to answer a questionnaire on the management of their animals and their farms distributed over the Italian territory. Six farms grouped their animals in paddocks according to the production characteristics (e.g. lactating, dry, stallions); three farms housed the stallions in single boxes. Most of the visited farms were family run and the number of animals cared for by a single person varied from five to 103 animals. All the farms but one performed mechanical milking with a modified goat milkmaid. Vaccinations were regularly performed only on two farms. All the foals received colostrum and suckled from their own mothers. Foals were nursed by their mother until 6-12 months old. During the separation period before milking, foals were usually (83%) housed in paddocks near their mothers with the possibility of visual and/or tactile contact, however such separations could be for up to 12 hours (17%). Even though the assessed sample was small, considerable differences were seen between farms, likely due to lack of uniform information available for the farmers. The adoption of scientific based procedures is suggested in order to improve both animal welfare and milk quality.

Lactation persistency and milk production are among the most economically important traits in the dairy industry. In this study, we explored the association of over 6.1 million imputed whole-genome sequence variants with lactation persistency (LP), milk yield (MILK), fat yield (FAT), fat percentage (FAT%), protein yield (PROT), and protein percentage (PROT%) in North American Holstein cattle. We identified 49, 3991, 2607, 4459, 805, and 5519 SNPs significantly associated with LP, MILK, FAT, FAT%, PROT, and PROT%, respectively. Various known associations were confirmed while several novel candidate genes were also revealed, including ARHGAP35, NPAS1, TMEM160, ZC3H4, SAE1, ZMIZ1, PPIF, LDB2, ABI3, SERPINB6, and SERPINB9 for LP; NIM1K, ZNF131, GABRG1, GABRA2, DCHS1, and SPIDR for MILK; NR6A1, OLFML2A, EXT2, POLD1, GOT1, and ETV6 for FAT; DPP6, LRRC26, and the KCN gene family for FAT%; CDC14A, RTCA, HSTN, and ODAM for PROT; and HERC3, HERC5, LALBA, CCL28, and NEURL1 for PROT%. Most of these genes are involved in relevant gene ontology (GO) terms such as fatty acid homeostasis, transporter regulator activity, response to progesterone and estradiol, response to steroid hormones, and lactation. The significant genomic regions found contribute to a better understanding of the molecular mechanisms related to LP and milk production in North American Holstein cattle.

SummaryThis study was carried out to investigate the fertility, milk production and body weight of ewes and the survival and growth characteristics of lambs of the indigenous Imroz and Kivircik sheep breeds. The Imroz and Kivircik sheep breeds are included among the genetic resources in the project for the conservation of the indigenous breeds in Turkey.Conception rates for Imroz and Kivircik ewes were 57.6% and 81.7% respectively, litter sizes were 1.2 and 1.2 respectively, milk yields were 89 kg and 62 kg respectively and average live weights (2–7 years of age) were 43 kg and 55 kg, respectively. Imroz and Kivircik lambs had survival rates at weaning (90th day) of 98% and 96%, birth weights of 3.3 kg and 4.1 kg and weaning weights of 19.8 kg and 28.0 kg, respectively.The results showed that the Kivircik sheep were heavier and the lambs had a better growth rate until weaning than the Imroz breed. However, the milk production of the Imroz ewes was higher than that of Kivircik. The lambs of both breeds had a satisfactory survival and growth rates until weaning and these results might be regarded as a desired adaptation of the Imroz and Kivircik lambs to the environmental conditions of the Marmara Region.

Abstract Stereotypic behavior is repetitive, invariant behavior with no obvious goal or function and may indicate negative welfare. Non-nutritive oral behaviors are the most common form of stereotypic behavior in captive ungulates and these include tongue rolling where the cow’s tongue is extended, moving inside and outside of the mouth while the cow is not eating. We assessed the prevalence of tongue rolling in a large commercial dairy herd located in the United States by video recording cattle (n = 10,000) during three consecutive milkings on two rotary milking parlors. Associations between tongue rolling behavior, breed, age, days in milk, pregnancy status and milk production were assessed. In total, 29% percent (2,931) of cows were observed tongue rolling on the rotary parlor during at least one milking; 6% (613) were observed tongue rolling during two milkings; and 1.6% (164) were observed tongue rolling during all three sampling periods. Breed was the only variable associated with tongue rolling in the rotary parlor with nearly twice the proportion of Jersey (33%) vs Jersey X Holstein (17%) exhibiting tongue rolling behavior (P < 0.0001). The higher incidence of tongue rolling among Jersey vs Jersey X Holstein cattle within a shared environment suggests a strong genetic component that warrants further investigation. Validated sampling strategies for assessing tongue rolling in dairy cattle are needed.

The intensification of livestock production and the focus on economic gains of agricultural policy have resulted in animal welfare related challenges. In many countries the societal concern for the welfare of farmed animals is increasing. Whereas policymakers on the European Union’s level and in EU member states have passed specific farm animal protection laws, the existing policies do not always guarantee the welfare of farmed animals. At the same time, the engagement of market actors in the field is increasing. This article explores the development of public and private policies in two countries with very different levels of regulation. By conducting a comparative analysis of public and private policies in Germany and France, the findings illustrate that, although they have different starting points, retailers in both countries are getting increasingly involved in farm animal welfare. In addition, there is evidence that governmental policies are shifting from regulatory to voluntary approaches in cooperation with the private sector. Given that in both countries these dynamics are a very recent development, it remains to be seen whether governmental actors will (re-)assume the lead in the field, whether they will engage in cooperation with private actors, or whether they will leave the task of agricultural restructuring to the market.
