The Five Freedoms: welfare ideals for farm animals 1 FREEDOM FROM HUNGER AND THIRST

The Five Freedoms: welfare ideals for farm animals 1 FREEDOM FROM HUNGER AND THIRST by ready access to fresh water and a diet to maintain full health and vigour. 4 FREEDOM TO EXPRESS NORMAL BEHAVIOUR 2 FREEDOM FROM DISCOMFORT 5 FREEDOM FROM FEAR AND DISTRESS by providing an appropriate environment including shelter and a comfortable resting area. by providing sufficient space, proper facilities and company of the animal’s own kind. by ensuring conditions and treatment which avoid mental suffering. 3 FREEDOM FROM PAIN, INJURY OR DISEASE by prevention or rapid diagnosis and treatment. 3

Animals have certain innate behaviors The question to ask yourself is: Does the environment or management system we provide restrict their ability to express those behaviors? In as much as is possible – the objective should be to provide an environment that permits normal behavior, provides basic animal needs and limits or reduces fear and distress. J. K. Shearer DVM, MS.

Calf Needs and Natural Behaviors • Suckling behavior – Nipple bottle versus bucket feeding?

Calf Needs and Natural Behaviors • Suckling behavior – Nipple bottle versus bucket feeding? • Resting or sleeping – Tethered housing? Pens that restrict ability to turn around • Need to explore and socialize – Individual pens or stalls • The need for exercise – How much space? • Grooming behavior – Individual housing restricts grooming behavior

Basic Dairy Calf Housing Neonates / Individual housing: • Must be clean and dry

Basic Dairy Calf Housing Neonates / Individual housing: • Must be clean and dry • Calves must be able to turn around in individual housing – “Turn around without touching sides”? – “Extend feet without touching sides”? • Nesting (bedding) in cold weather • Calf-calf interaction • Tether OK if can turn around 9

Neonates / Group housing: positives negatives • Provides stimulation and enrichment • Allows calf play • Increased calf to calf interaction • Allows all postures • Well suited for small groups • Sanitation can be difficult with large groups • Contagious disease control procedures more difficult 11

Veal Calf Production and Welfare - Industry Facts • Six primary veal producing states

Veal Calf Production and Welfare - Industry Facts • Six primary veal producing states - Indiana, Michigan, New York, Ohio, Pennsylvania and Wisconsin. • Veal farmers purchase surplus dairy calves, primarily male Holstein calves, at about 100 pounds live weight and raise them for approximately 18 -20 weeks, until they weigh upward of 475 -500 pounds.

What is “Veal”? • • Soft, tender pale meat of young calves Calves are 1 day to 5 months of age Color of meat is determined by iron and copper Exercise is reduced in the belief it softens the meat • Kept monogastric in belief that rumen fermentation changes flavor and texture of the meat • “flavor and texture is imparted by the chef” 14

Veal Calf Production and Welfare Several categories of veal calves: • “Bob veal” – 1 day to a few weeks of age • Veal – Typically 5 months and 500 pounds • Special-fed veal – Rose or pink veal – More iron and copper in calf – “Red veal” 15

“Classic” Veal Production Welfare Issues • Calves are not castrated or dehorned (a welfare

“Classic” Veal Production Welfare Issues • Calves are not castrated or dehorned (a welfare positive) • Tethered in place – Cannot turn around or contact other calves – Short tether does not allow normal movement • Fed liquid only (milk replacer) diet – Rumen not developed; no cud-chewing – Rumen development can be considered normal physiology 16

Welfare Issues with “Traditional Veal” • Behavior – Limited or no contact with other

Welfare Issues with “Traditional Veal” • Behavior – Limited or no contact with other calves – Stereotypy of licking side (excessive grooming) from lack of rumination or suckling • “hair balls” in abomasum (bezoar) • Deficient in iron – Iron for calf comes from soil – Intended to reduce hemoglobin • Housed on raised floors to prevent eating dirt (iron) – Wooden slated floors can damage knees as calf gets heavy • Indoors, often in dark rooms 17

EU Regulations for Humane Veal Production • Housed in groups after 8 weeks of

EU Regulations for Humane Veal Production • Housed in groups after 8 weeks of age – Allows calf interaction (play) • Fed dry feed to cause rumen development – Considered normal physiology • Iron fed or injected 18

Current Veal Production in the US “Veal farmers are ahead of schedule as they

Current Veal Production in the US “Veal farmers are ahead of schedule as they work to meet the American Veal Association (AVA) commitment to transition all veal farms to group housing by 2017. An April survey found that 34. 8 percent of the veal calves currently going to market are raised in group-housing facilities. ” “In May 2007, the AVA’s board of directors voted unanimously to adopt a resolution calling for all U. S. veal farms to transition to group-housing systems by Dec. 31, 2017. The board also encouraged more research to aid farmers in the transition. ” • Veal calves move to group housing By Dairy Herd news source | Monday, June 08, 2009 19

AVMA policy: Veal Calf Management • Calves must be fed diets that provide adequate energy, protein and minerals to maintain good health and positive growth. Diets must be balanced to prevent nutritional deficiencies and their consequences, including but not limited to iron deficiency with subsequent anemia. Water must be provided from birth. Dry feed must be provided for rumen development and to allow the normal process of rumination. All calves must be fed colostrum after birth. • http: //www. avma. org/issues/policy/animal_welfare/veal_calf_management. asp 23

AVMA policy: Veal Calf Management • Housing must be ventilated to provide fresh air and to prevent buildup of ammonia or pathogens. Floors and bedding must be clean, dry and maintained to prevent injuries, and allow calves to maintain normal body temperature in cold weather. • http: //www. avma. org/issues/policy/animal_welfare/veal_calf_management. asp 24

Tail Docking of Cattle

Tail Docking of Cattle

Cattle Tail Docking Summary history of cattle tail docking: • Began in New Zealand

Cattle Tail Docking Summary history of cattle tail docking: • Began in New Zealand with erroneous association with Leptospirosis in people – Cows get different Leptospires than people • Considered to control mastitis – Increased manure on tail thought to be associated with increased mastitis • Was brought to USA to control Somatic Cell Count when r. BST introduced 26

Painful procedures If a procedure will cause pain: 1) is the procedure necessary for the cow or society (i. e. a benefit)? 2) if the procedure will cause pain and is necessary, then pain management must be considered. 31

Benefits from tail docking • Not associated with mastitis control or lower Somatic Cell

Benefits from tail docking • Not associated with mastitis control or lower Somatic Cell Count – “No significant differences were observed in SCC, udder cleanliness, or intramammary infection between docked and intact cattle. 10 Although docked cattle had a higher incidence of mastitis in one study, 9 the difference was not statistically significant. ” AVMA Tail Docking Backgrounder for references http: //www. avma. org/reference/backgrounders/tail_dock ing_cattle_bgnd. asp http: //www. ohiovma. org/ 32

AVMA policy: Tail Docking of Cattle The AVMA opposes routine tail docking of cattle. Current scientific literature indicates that routine tail docking provides no benefit to the animal, and that tail docking can lead to distress during fly seasons. When medically necessary, amputation of tails must be performed by a licensed veterinarian. (Oversight: AWC; EB 04/2004; reaffirmed 04/2009) 34
