Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The study will be a cluster randomized control trial conducted in Marsabit County and will involve a total of 1800 households that own livestock and have children 5 years and below. The households will be divided into three groups and each group will have a total of 600 households. Group one, will receive livestock feed enough to maintain 2-3 milking animals during the critical dry period. The second group will receive similar livestock feed but will also receive education and counselling on human nutrition. The third group will be the control arm and will not receive any of the two interventions.
The study will aim to estimate how these interventions impact stunting and underweight in children and weight gain for pregnant women by collecting data on middle upper arm circumference, height, weight, and weight-gain during pregnancy every three months in a year. In addition, data on food consumption patterns such as number of meals taken, type/diversity of foods consumed including animal source foods, frequency of times and quantity of specific foods consumed) on at least 6-weekly basis will be collected. To further understand this problem the investigators will collect human illness data including on fever, diarrhoea, and respiratory syndromes among study participants during the regular visits. Socio-economic data including household demographics, incomes, expenditures, asset accumulation, gender roles, and workload and time allocation will be collected quarterly. Biological samples will be collected (venous blood and mother's milk) at recruitment, six months and 12 months. Screening for infections such as brucellosis, micronutrient and mycotoxin analysis will be conducted on the biological samples in order account for infections or conditions that could have an impact on nutritional status of study participants. The study will also assess which of the interventions provide value for money given that resources are scarce.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Objectives: Here the investigators implement a cluster randomized control study trial to determine the effect of providing livestock feed, livestock feed and nutritional education and counselling during critical dry periods on household milk availability and consumption, and the risk of malnutrition in pregnant and lactating mothers, and children 5 years and below.
Methods: A total of 1800 households owning livestock and with children 3 years and below in Marsabit County will be enrolled into three equal groups (arms) of 600 households each. Each household and participant will be followed for 18 months. Households in Arm 1 will receive livestock feed enough to maintain 2-3 milking animals during the critical dry period. Arm 2 will receive similar livestock feed and human nutritional education and counselling. Arm 3 (control arm) will not have any of the two interventions. Primary outcome measures will be child anthropometric indicators (height-for-age, weight-for-age and middle upper arm circumference) and maternal anthropometric measures (middle upper arm circumference, height, weight, weight-gain during pregnancy) collected quarterly. Data on a 24-hour recall of diet (number of meals taken, type/diversity of foods consumed including animal source foods, frequency of times and quantity of specific foods consumed) will be collected every 6 weeks. To control for additional factors that would influence nutritional status, the investigators will collect human health syndromic data (fever, diarrhoea, respiratory syndromes) and livestock health data every six weeks and socio-economic data quarterly including household demographics, incomes, expenditures, asset accumulation, gender roles, workload and time allocation. To control for exposure to infections such as brucellosis in humans and animals and for micronutrient and mycotoxin analysis, biological samples (venous blood of mother and child), animal biological samples (blood and milk) and household drinking water will be collected at recruitment, 6 months and at 12 months. The study will test the cost-effectiveness of livestock interventions and nutritional counselling in prevention of malnutrition and its health consequences, compared to treatment of malnutrition. Cost data associated with each study arm will be tracked to provide estimates of resources required to scale up for implementation. Results from this study will form the basis for monitoring efficiency and effectiveness of interventions aimed at reducing seasonal spikes in levels of acute malnutrition in children under five years and pregnant and lactating women in pastoralist communities.
Study duration: Each study household and participant is followed for a period of 24 months from the time of enrolment into the study.

RANDOMIZED
FACTORIAL
i) Intervention arm 1: Livestock feed only.
Households in villages assigned to intervention arm 1 will receive a pre-defined amount of livestock feed to maintain two tropical livestock units for a total of 60 days during the dry season (when animals would be moved away in search of pastures).
ii) Intervention arm 2: 1.Provision of Livestock feed, 2. Nutritional counselling
Households recruited into intervention arm two will receive livestock feeds and will be enrolled in a nutritional education and counselling program.
iii) Control arm
The households recruited under this arm will receive none of the two study interventions. These households will receive identical assessment and data collection like other study households in the study.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intervention arm 1: Livestock feed only
Households in villages assigned to intervention arm 1 will receive a pre-defined amount of feed to maintain two tropical livestock units for a total of 60 days during the dry season (when animals would be moved away in search of pastures).
Provision of livestock feeds
Households will receive livestock feeds (ranch cubes) for the select lactating animals during the dry season
Intervention arm 2: 1. Provision of Livestock feeds, 2. Nutrition counselling
Households recruited into intervention arm two will receive livestock feeds similar to intervention arm 1 and will be enrolled in a nutritional education and counselling program through Infant and Young Child Nutrition (IYCF) feeding program and household food utilization. The IYCF program through the Baby Friendly Community Initiative (BFCI) will include the promotion of exclusive breastfeeding in the first six months, continued breastfeeding up to the age of two years, adequate complementary feeding, hygiene promotion and the uptake of child health services including immunization, treatment of illness, moderate and severe acute malnutrition and micro-nutrient supplementation.
Provision of livestock feeds
Households will receive livestock feeds (ranch cubes) for the select lactating animals during the dry season
Nutrition counselling
Households will receive livestock feeds (ranch cubes) for the select lactating animals and will also be enrolled in to a nutrition counselling programme
Control arm
The households recruited under this arm will receive none of the two study interventions. These households will receive identical assessment and data collection like other study households in the study. Their access to support through other interventions will be monitored. Households within the control arm will receive nutritional counselling and education given outside of the project. This is mainly at health facilities when mothers present for antenatal care or visit health facilities seeking healthcare. On some occasions in places where community health volunteers are present, nutritional counselling and education may be provided at the community level. The study instruments have been designed to collect information at the household level if such nutritional counselling and education has been provided.
