Aleri JW, Nguhiu-Mwangi J, Mulei CM. "Welfare of dairy cattle in the smallholder (zero-grazing) production systems in Nairobi and its environs.". 2012. Abstract

Animal welfare is defined as the ability of an animal to interact comfortably with its environment through its physiological, psychological and behavioural systems. About 70% of dairy production in Kenya is from the smallholder production systems. These production systems are negatively impacted by a number of factors including poor nutrition, substandard husbandry and management practices, lack of appropriate farm inputs, diseases and low incomes. These factors influence the welfare of dairy cattle, hence their importance for its evaluation. This study was therefore designed with the following objectives: 1. to determine the welfare of dairy cattle in the smallholder production units in Nairobi and its environs, 2. to determine the risk factors contributing to poor welfare of dairy cattle in the smallholder production units, 3. to determine the indicators of poor welfare of dairy cattle in the smallholder production units, 4. to determine the farmers’ and stockmen’s perspectives of animal welfare. These objectives were achieved through a cross-sectional study carried out in 80 smallholder dairy units purposively selected in Nairobi and its environs, in which 306 dairy cows were examined. The welfare of cattle in these dairy units was evaluated through several methods which included: visual observations for animal- and farm-level factors that indicate poor welfare of cattle; taking measurements of dairy housing unit dimensions such as cubicle, walk-alley, kerb and feeding bunk; and using a structured questionnaire to interview farmers and stockmen on nutritional regimes and other management practices such as removal of slurry, milking techniques, record keeping and disease control. These factors were recorded and later analyzed. Analyses included descriptive statistics, and simple associations using chi-square at p< 0.05 significance level. Over 80% of these smallholder units had factors that contributed to poor welfare of dairy cattle. These factors included under-size cubicles, small walk-alleys, too high feeding bunks with traumatic edges, too low positioning of neck rails at the feed bunks, sharp objects and edges within the housing units and dilapidated housing structures. The main evidence of poor welfare was injuries on the animals. The body condition score (BCS) of the cows was the main indicator of welfare relating to feeding. Presence of injuries or scars on the skin at various parts of the body was considered a positive indicator of poor welfare either associated with housing structures, management practices or animal interactions. Other causes of poor welfare of the cows were hind-limb tying during milking, teat pulling during hand-milking, more than 24-hour delay before sick cows were treated, and mixing of cattle of different age-groups in the same compartment. Cow-human interaction was poor as evidenced by fearful response and long avoidance distance. This study concludes that poor welfare of dairy cattle exists in all the smallholder units evaluated, which is mainly caused by improper housing and management. Training of farmers and stockmen on animal welfare issues would therefore be a prerequisite to the improvement of dairy cattle welfare. Research on the physiological response to poor welfare of dairy cows in the smallholder units needs to be carried out to enhance the understanding of the impact of these risk factors on smallholder dairy animals.

Mogoa EGM, Okanga S, Muchemi G, Munene E, Maingi N. "Gastrointestinal parasites of free-ranging colobus monkeys (Colobus angolensis palliatus) in Kwale District, Kenya coast.". 2006. Abstract

Approximately 2000 black and white Angolan colobus monkeys (Colobus angolensis palliatus) remain in Kwale District, Southern Kenya. They are threatened by deforestation due to private development countrywide. Primates can act as indicators of the degree of change in a habitat, as habitat changes potentially affect how they deal with parasitic infection (Mittermeier & Cheney, 1987). An increasing human population in Diani, Kwale District, encroaches on the forest habitat of the Angolan colobus and brings the primate species into closer proximity with rubbish and waste from the local human population. This study established the type and distribution of gastrointestinal parasites in Angolan colobus in Diani Forest, Kwale according to age and sex and the effect of varying habitat integrity on parasite prevalence.

Researchers in both human and veterinary anaesthesia continue searching for better and safer anaesthetics substances which can cause damage and even death if given in incorrect doses or concentrations. Apart from looking for newer drugs, research is going on to find better routes of administration and drug delivery systems. The anaesthesia of millennium will focus on the development of substances that mimic the proteins and peptides made by the body. Newer delivery systems include patches, ionotrophoretic techniques and transmucosal delivery are being tested and/ or being practiced. This paper highlights on some of the developments and the possible future directions in anaesthesia

Data relating to reproductive parameters of German shepherd bitches were collected from registered German shepherd dog (GSD) breeders with information kept over a 15-year period (1982-1997). The information obtained was verified using the East African Kennel Club records. A total of 594 bitches from 280 breeders were recorded. From these, 798 heats were observed, 594 of which were used for breeding, resulting in 3592 puppies. The mean age at puberty was 519.0 +/- 41 days. Heats occurred throughout the year, although significantly (P < 0.05) higher and lower incidences were observed in October and April respectively Pregnancy significantly (P < 0.01) increased interoestrous interval, which was 247.8 +/- 99.6 and 183 +/- 52 days among bred/pregnant and non-bred bitches respectively. Most bitches in oestrus (73.7%) were bred, and breeding was carried out throughout the year, with a distribution closely related to that of heat incidence. Subsequently, whelping occurred throughout the year, and 95.5% of the bitches that were mated whelped. A mean gestation period of 60.6 +/- 5.1 days was observed. The mean litter size was 6.4 +/- 0.4 puppies, and did not differ significantly between months. The preweaning losses were low, with 2.3% stillbirths, 0.9% culls and 11.4% mortalities
