This study was carried out from November 2007 to March 2008 to identify the species and to determine the burden of small intestinal helminth parasites of sheep and goats slaughtered in Hawassa, southern Ethiopia. Intestines of 116 sheep and 71 goats were examined using standard procedures. Three species of parasites namely Trichostrongylus colubriformis, Bunostomum trigonocephalum and Moniezia ...
Goats’ milk adulteration with cows’ milk is becoming a big problem. In the past, the urea-polyacrylamide gel electrophoresis assay with different motility of αS1-casein has been applied for the identification of cows’ milk adulteration. The detection sensitivity is 1.0%. The aim of this study was to develop a faster and more sensitive method to detect cows’ milk which may be present in adultera...
Dietary fiber contributes significantly to the balancing of nutrient requirements in goats. Dietary fiber also plays a pivotal role in goat production through its influence in and interaction with the intake and digestion of nutrients. Physiological regulation (feedback from metabolic factors) of intake is dominant in goats fed high-concentrate diets, while physical fill is the predominant fact...
Susceptibility of sheep to scrapie, a transmissible spongiform encephalopathy of small ruminants, is strongly influenced by polymorphisms of the prion protein gene (PRNP). Breeding programs have been implemented to increase scrapie resistance in sheep populations; though desirable, a similar approach has not yet been applied in goats. European studies have now suggested that several polymorphis...
West African Dwarf (WAD) and Red Sokoto (RS) goats were experimentally infected with the Kafanchan strain of Trypanosoma congolense and the course of the infection was monitored. The organism was pathogenic and produced fatal disease in the goats, which was characterized by rapid progressive anaemia, leucocytosis, weight loss and death. All RS goats died within 11 days of infection, and had a m...
Sub-fertility is one of the most common problems observed in crossbred males, but the etiology remains unknown in most of the cases. Although proteomic differences in the spermatozoa and seminal plasma between breeds have been investigated, the possible differences at the sperm precursor cells and supporting/nourishing cells have not been studied. The present study reports the differential prot...
Two component traits of litter size of pigs, ovulation rate and embryonic survival, were examined in Meishan and composite white crossbred gilts and sows. At puberty, an ovulation rate of 12.5 was similar for Meishan (118 +/- 3 d of age) and crossbred gilts (217 +/- 3 d of age). The number of corpora lutea (CL) increased (4.3 CL) markedly (P < .01) from puberty to the sixth estrous period (220 ...
Sixty entire male pigs from 2 distinct genotypes (30 Alentejano purebred, an autochthonous fatty genotype, and 30 commercial crossbred pigs, a lean genotype) were used to investigate the effects of dietary CP reduction and low-Lys levels on growth performance, carcass traits, and meat quality. Pigs with 59.9 ± 2.0 kg BW were randomly assigned within each genotype to 1 of 3 diets [normal CP diet...
