Histopathological effects of alternative feedstuffs (sesame hulls and Prosopis juliflora) on ruminal walls in black goat kids in Jordan
This study evaluated the histopathological effects of alternative feedstuffs on ruminal walls and, subsequently, the impact on growth performance of black goat kids in Jordan. Male goat kids (n = 62, BW = 17.1 ± 2.0 kg, age = 120 ± 5 days) housed in individual pens were randomly assigned to one of s...

| Summary: | This study evaluated the histopathological effects of alternative feedstuffs on ruminal walls and, subsequently, the impact on growth performance of black goat kids in Jordan. Male goat kids (n = 62, BW = 17.1 ± 2.0 kg, age = 120 ± 5 days) housed in individual pens were randomly assigned to one of seven diets for 84 days. Treatment diets were prepared by partially replacing barley in the control diet (CTL; n = 9) with different levels (10%, 15%, or 20%) of Prosopis juliflora pods (JP; n = 26) or partially replacing barley and soybean meal in the control diet with different levels of P. juliflora pods (10%, 15%, or 20%) plus sesame hulls (20%, 15%, or 10%; PJSH; n = 27). All kids were slaughtered and sections from ruminal walls were examined for vacuolar degeneration, dysplasia, hyperplasia, hyperkeratosis, stunting, submucosal inflammation, submucosal oedema, erosions, lymphangiectasia, and ulcers. Dietary treatments had no effects on all studied histopathological changes. The growth rate of kids was negatively correlated (P ≤ .05) with submucosal oedema and inflammation. However, the severity of submucosal oedema and inflammation was not affected by dietary treatments. Alternative feedstuffs had no detrimental histopathological effects on ruminal walls of goat kids. |
