Adejoro, Festus Adeyemi; Hassen, Abubeker; Thantsha, Mapitsi Silvester (Asian-Australasian Association of Animal Production Societies, 2019)OBJECTIVE : The use of tannin extract and other phytochemicals as dietary additives in ruminants is becoming more popular due to their wide biological actions such as in methane mitigation, bypass of dietary protein, ...
-
Ibrahim, Shehu Lurwanu; Hassen, Abubeker (MDPI, 2021-11-09)Tannin has gained wider acceptance as a dietary supplement in contemporary animal nutrition investigations because of its potential to reduce enteric methane emission. However, a major drawback to dietary tannin intake ...

Lukusa, Kambulu; Hassen, Abubeker; Lehloenya, Khoboso C. (Wolters Kluwer- Medknow, 2021-01-18)OBJECTIVE : To evaluate the effect of cooling rates, selenium supplementation, and three semen extenders on cooled and frozenthawed Saanen buck sperm. METHODS : Twenty Saanen bucks were divided into two groups: the selenium ...

Effect of diets differing in rumen soluble nitrogen on utilization of poor-quality roughage by sheep Mentz, A.M.; Van Niekerk, Willem A.; Hassen, Abubeker; Coertze, R.J. (Roelof Johannes); Gemeda, B.S. (Belete Shenkute) (South African Society for Animal Science, 2015-12-14)This study investigated the effects of replacing rapid-release nitrogen (N) from urea with a graded level of slow-release N (Optigen® II) source on intake, digestibility, rumen fermentation and microbial protein synthesis, ...
-
Gemeda, B.S. (Belete Shenkute); Hassen, Abubeker; Odongo, N.E. (Pakistan Agricultural Scientist's Forum, 2014)This study aimed to evaluate the effects of cellulase and xylanase plus enzymes on in vitro ruminal fermentation of Eragrostis curvura hay, maize stover and a total mixed ration (TMR) at six levels of application. The ...
-
Leketa, Khabane; Donkin, Edward Francis; Hassen, Abubeker; Akanmu, Abiodun Mayowa (South African Society for Animal Science, 2019-04-14)This study examined the effects of diets with two protein sources (oilseed cake meal (OSCM) and Leucaena leucocephala hay) on the performance of lactating goats that were fed a total mixed ration (TMR). Thirty Saanen milk ...
