Reproductive Performance of Rahmani Ewes in Breeding and Non-Breeding Seasons Aaccording to Different Hormonal Protocols

Abstract

Therty Rahmani ewes used to study the possibility of inducing estrous and ovulatory activities by hormonal treatments during the breeding season (September) or non-breeding season (May) for the purpose of improving fertility. Ewes were divided into three similar groups (10 heads/group) for each breeding season according to the type of hormonal treatments. Fresh diluted semen was used for AI, semen was deposited into the cervix. Results showed that estrus rate was higher (P<0.

Performances, carcass characteristics, and economic benefit of yearling Hararghe highland rams fed diet containing concentrate mixtures and sugarcane bagasse or rice husk treated with Trichoderma viride and effective microorganisms

“…The better performances recorded in sheep fed a total mixed ration containing biologically treated by-products treated was attributed to the degradation of cell wall structure, which leads to increase digestibility and protein content of the diets. This in line with the findings of various researcher who reported that incorporating biologically treated roughage in the diets of ruminant increases feed intake, improves digestibility, and increases FCE (Abdel-Azim et al, 2011;Belewu et al, 2003;El-Bordeny et al, 2015;Fouda, 2008). Moreover, Gado et al (2006) found that goats consumed with biologically treated SCB had higher DMI and average body weight gain.…”

“…According to Jalč (2002), the use of fungi and/or their enzymes that metabolize lignocellulose is a potential biological treatment to enhance the nutritional contents of agroindustrial by-products. Most research reports indicate that feeding ruminants with biologically treated roughage increases feed intake, improves digestibility, and increases feed conversion efficiency (FCE) compared to untreated (Abdel-Azim et al, 2011;Belewu et al, 2003;El-Bordeny et al, 2015;Fouda, 2008). Moreover, growing animals fed on biologically treated roughages showed better daily gain (Allam et al, 2006), FCE, and pre-slaughter live weight (El-Marakby, 2003) compared to animals fed untreated roughages.…”
