Consumers have a right to safer foods, and traceability is one approach to meeting their expectations. Kenya does not have an operational animal traceability system, and while a few initiatives have been piloted, these have only focused on the beef value chain. In this paper, we begin a discussion on traceability in the pig value chain, with an initial focus on smallholder systems of Western Kenya. First, a background to local pig production is given, and a description of animal identification a...

The Nguni cattle breed has distinct populations that are adapted to the different ecological zones of Southern Africa. This study was carried out to assess genetic diversity and establish the relationships among South African (SA), Mozambican (Landim), and Swazi Nguni cattle populations, using 25 microsatellite markers. Genotypic data were generated from deoxyribonucleic acid (DNA) samples of 90 unrelated individuals of the three cattle populations, collected from government conservations and st...

Lameness is one of the most serious economic problems in dairy animals. The present study was undertaken to identify the SNPs associated with lameness in Vrindavani, a synthetic crossbred cattle developed in India. A total of 187 cows were screened for lameness at Cattle and Buffalo Farm, Indian Veterinary Research Institute, Izatnagar, India and 16.04% prevalence was noticed. The effect of age, body weight, parity, and peak yield was not significant on lameness score. Heritability estimate of l...

The effects of feeding corn steep liquor (CSL; 420 g/kg crude protein, DM basis) along with different cereal grains on performance, digestibility, blood metabolites, ruminal fermentation, and carcass characters of growing lambs were evaluated. The constant amount of CSL was included in basal diet (100 g/kg, DM basis) and grain sources as experimental treatments were as follows: (1) corn grain (CG), (2) barley grain (BG), or (3) wheat grain (WG). The eighteen individually fed Farahani lambs avera...

Identification of reservoirs and transmission routes of digital dermatitis (DD)-associated Treponema spp. is considered an effective means for controlling DD infection in dairy cows. The objective of this study is to identify and characterize the potential reservoir niches for DD-associated Treponema spp. from healthy udder cleft skin and foremilk in lactating dairy cows. A large dairy farm was visited weekly from March to July 2015. Clinical investigation revealed that a total of 25 lame cows h...

Newcastle disease (ND) is a major constraint to Kenya’s poultry production, which is comprised of approximately 80% indigenous chickens (ICs; caged and free-range system) and 20% exotic chickens (intensive system). This study analyzed cases reported as suspected ND in Kenya between 2005 and 2015. Of the suspected 332 ND reported cases from the three production systems in 27 locations within six Kenyan Agro-Ecological Zones (AEZs), 140 diagnosed as infected with avian orthoavulavirus 1 (AOaV-1; f...

This study examined rumen fermentation, histological, blood, and urinary characteristics as well as ammoniacal nitrogen concentration, pH, nitrogen balance, and microbial protein in lamb fed diets containing spineless cactus as the sole roughage source plus levels of wheat bran (WB) in comparison with a control diet based on spineless cactus and buffelgrass. Twenty-eight uncastrated, crossbreed lambs with an average initial weight of 22.6 ± 2.37 kg were used in the experiment. The treatments con...

The aim of the study was to investigate the influence of dietary supplementation of various levels of milk thistle (MT) on growth performance, oxidative stress, and immune response of natural summer stressed broilers. A total of 120 1-day old broiler chicks were distributed into 4 treatments: MT-0 (control), MT-5 (5 g/kg of MT), MT-10 (10 g/kg of MT), and MT-15 (15 g/kg of MT), each with 3 replicates having 10 birds per replicate. Results showed that overall feed intake, body weight, feed conver...

The present study reports the molecular and antigenic characterization of 13 bovine herpesvirus type 1 (BoHV-1) field viruses obtained from cattle with different clinical cases in Turkey between 1992 and 2017. We selected glycoprotein C (gC) of BoHV-1 as a target to detect and/or verify presence of the virus in suspect materials followed by virus isolation (VI) in MDBK cells. In seven out of 13 BoHV-1 positive samples, cytophatic effects (CPEs) were observed in MDBK cell cultures, although only ...

Milk and milk products play an important role in the diet of pastoralists in Ethiopia. However, only few studies have been conducted on the microbial contamination of milk and milk products in pastoral areas. Therefore, the objective of the present study was to assess the hygiene and safety of ready-to-consume milk and traditionally produced fermented milk products (yogurt) in Borana. A total of 203 raw milk and milk product samples collected from different points along the milk production and h...
