Welfare Challenges of Dairy Cows in India Identified Through On-Farm Observations

Welfare Status of Dairy Animals under Field Condition in Muzaffarnagar District of Uttar Pradesh (India)

This study aimed to evaluate the welfare status of dairy animals under field condition of India. The study was conducted in two blocks of Muzzaffarnagar district of Uttar Pradesh. Two villages from each blocks were purposefully selected for the study. Twenty farmers were selected from each village with a total of eighty farmers and categorized based on their landholding size as marginal (<1 hectare), small (1-2 hectare) and medium (2-10 hectare) and total of 20 welfare indicators were identified and grouped into three components viz., housing and other facilities -A, feeds and feeding practices - B and animal health, performance and behavior- C with a weightage of 30, 30 and 40, respectively. The total score obtained was used to categorize the welfare status of the farms as good (60-80), average (40-60) and poor (<40). In one-way ANOVA, the mean welfare score was significantly (P < 0.05) higher in medium farmers than marginal and small farmers and proportions of farmers under good, average and poor welfare ranking was 12.50, 83.75 and 3.75%, respectively. Whereas, only 12.50% farmers achieved an acceptable welfare level across farmers categories. From this study it can be concluded that dairy animal welfare at most of the dairy farmers under field condition was average and only a few farmers had acceptable level of welfare.

Constipation anti-aging effects by dairy-based lactic acid bacteria

Constipation, which refers to difficulties in defecation and infrequent bowel movement in emptying the gastrointestinal system that ultimately produces hardened fecal matters, is a health concern in livestock and aging animals. The present study aimed to evaluate the potential effects of dairy-isolated lactic acid bacteria (LAB) strains to alleviate constipation as an alternative therapeutic intervention for constipation treatment in the aging model. Rats were aged via daily subcutaneous injection of D-galactose (600 mg/body weight [kg]), prior to induction of constipation via oral administration of loperamide hydrochloride (5 mg/body weight [kg]). LAB strains (L. fermentum USM 4189 or L. plantarum USM 4187) were administered daily via oral gavage (1 × 10 Log CFU/day) while the control group received sterile saline. Aged rats as shown with shorter telomere lengths exhibited increased fecal bulk and soften fecal upon administration of LAB strains amid constipation as observed using the Bristol Stool Chart, accompanied by a higher fecal moisture content as compared to the control (p < 0.05). Fecal water-soluble metabolite profiles showed a reduced concentration of threonine upon administration of LAB strains compared to the control (p < 0.05). Histopathological analysis also showed that the administration of LAB strains contributed to a higher colonic goblet cell count as compared to the control (p < 0.05). The present study illustrates the potential of dairy-sourced LAB strains as probiotics to ameliorate the adverse effect of constipation amid aging, and as a potential dietary intervention strategy for dairy foods including yogurt and cheese.

Development of a welfare assessment protocol and assessment of dairy cattle welfare in Haryana and Punjab states of Northern India

The aim of this study was to develop an on-farm dairy cattle welfare assessment protocol at different-sized farms in two major commercial dairy farming states in India. For developing the protocol, the basic 'Integrative Diagnostic System Welfare' (IDSW) framework was modified to include three welfare components (animal housing and other facilities; feeds and feeding practices; and animal health, performance and behaviour) and 20 welfare indicators (ten resource- and ten animal-based). Each indicator was weighed on a value scale with an aggregate welfare score of 100. The protocol was tested for feasibility, validity and reliability using Cronbach's alpha and Guttman split-half coefficient. Using this protocol, welfare was assessed on 60 commercial farms in Punjab and 50 in Haryana, divided into three adult herd sizes: small (S < 20), medium (M = 21–50) and large (L > 50). Welfare scores in L (76.60 [± 1.70]) and M (68.40 [± 2.27]) sized herds in Punjab were higher than in S herds (60.80 [± 2.77]). In Haryana these were higher in L (68.1 [± 1.18]) than in S (60.50 [± 2.74]) and M (59.35 [± 2.17]) sized herds. The aggregate average welfare score was higher in Punjab (68.60 [± 1.49]) than in Haryana (62.65 [± 2.02]). Welfare at more than 75% of the farms in Punjab and more than 50% of those in Haryana was judged as 'acceptable.' Six welfare indicators in Punjab and eight in Haryana were most compromised. Four indicators (microclimate protection measures, availability of milking parlour, cow cleanliness and reproductive efficiency) were the most compromised indicators in both states. To improve dairy cattle welfare in these states we recommend an emphasis on improving housing and feeding conditions, especially at small and medium farms, along with heat stress amelioration measures and improving hygiene and reproductive efficiency at all farms.

Microbiota and Serum Metabolic Profile Changes in Korean Native Hanwoo Steer in Response to Diet Feeding Systems

The diversity of bacteria and their function in cattle gastrointestinal tracts can influence animal welfare. Next-generation sequencing (NGS) was used to investigate microbial diversity in the feces of Hanwoo steers reared under natural grazing (GS) and housing (HS) systems. Additionally, serum metabolic parameters, such as liver and kidney markers and mineral and lipid content changes, as well as their correlation with pyrotags, were studied. A total of 6468 ± 87.86 operational taxonomic units (OTUs) were identified in both steer groups, of which 3538 ± 38.17 OTUs were from grazing steer and 2930 ± 94.06 OTUs were from GS. Chao1 index analysis revealed a higher bacterial richness in GS. The dominant bacterial taxa were Bacteroidetes and Firmicutes. GS showed lower Bacteroidetes and higher Firmicutes abundance than HS. The serum of HS showed consistent increases in gamma-glutamyl transpeptidase (γGTP), glucose (GLU), total cholesterol (T-CHO), and triglyceride (TG) levels. The impact of GS on animal health and serum metabolic markers was strongly correlated with microbiota. As shown in this study, grazing has a significant impact on the fecal microbiota at the phylum and family levels, as well as the serum biochemical metabolites of Hanwoo steers.

The Topic of the Ideal Dairy Farm Can Inspire How to Assess Knowledge about Dairy Production Processes: A Case Study with Students and Their Contributions

The dairy farm and on-farm production processes are the subject of numerous evaluations. These are not only evaluations of the economic efficiency of milk production. Opinions expressed by various social groups are also an important contribution to improving the approach to milk production on the farm. As a result of such opinions, a vision of an ideal dairy farm may be formed. The aim of the study was to develop the thematic area of an ideal dairy farm in the opinion of two groups of students who were learning remotely (in the distance learning system) due to the Covid-19 pandemic. The first group consisted of six Erasmus+ students. The second group consisted of 70 full-time Polish students. As part of their homework, the students answered three questions about the ideal dairy farm. Students had 4 weeks to do their homework. Erasmus+ students’ homework was used to propose a ranking method for assessing the answers to three questions by the students themselves. Homework of Polish students was used to analyze the frequency of using certain keywords. Polish students, in their homework on the ideal dairy farm, mainly used the basic concepts related to dairy production. Unfortunately, a very small number of students used terms that represent a responsible approach to dairy production, including ethical aspects, freedom, sustainability, animal pain, antibiotics, and organic milk production. In conclusion, it was indicated that the curriculum should be structured in such a way as to raise students’ awareness of dairy production and its current challenges.

Cattle Cleanliness from the View of Swedish Farmers and Official Animal Welfare Inspectors

Dirty cattle have been commonly recorded in official animal welfare inspections in Sweden for years. The relevant authorities have initiated work to better understand the causes of dirty cattle, in order to improve compliance and standardize the grounds for categorizing a farm as non-compliant with welfare legislation when dirty animals are present. This study investigated the occurrence of dirty cattle in official animal welfare controls, on Swedish cattle farms, and examined farmers' views on the reasons for non-compliance and on key factors in keeping animals clean. The data used were collected by animal welfare inspectors at the county level during the regular official inspections of 371 dairy and beef cattle farms over two weeks in winter 2020. In addition to completing the usual inspection protocol, the inspectors asked farmers a set of questions relating to why their animals were clean or dirty. Dirty cattle were found on 49% of the farms inspected, but only 33% of the farms were categorized as being non-compliant with Swedish welfare legislation. According to inspectors and farmers, dirtiness in cattle depends mainly on management routines, which is a promising result since routines can be improved. The results also revealed a need for better guidance for inspectors and farmers on when dirtiness should be categorized as non-compliance with animal welfare legislation.
