Immunization Against Inhibin Increases Sperm Production in Young Beef Bulls

A Comparative Study of Biodiesel Production from Beef Bone Marrow

This study is concerned with the viability of producing biodiesel from waste beef bone fat and evaluate this product according to the quality requirements defined by ASTM D- 6751. Accordingly, beef bone fat was heated to remove the moisture under vacuum at 60 . Alkaline Catalysed Transesterfication was carried out by  using 6:1 molar ratio of ethanol to fat in the presence of 1% w/w sodium hydr...

Bull Power: Examination of Beef Cattle Bulls for Breeding Soundness

T evaluation of bulls for breeding soundness is an effective and reliable way to identify bulls that are potentially poor breeders. This management technique can be used to greatest advantage if culling occurs before bulls are turned out with females. Also, the evaluation is an important means available to the producer for predicting bulls with satisfactory to excellent potential. This informat...

Anaero bic heat production of bull spermatozoa.

A micro-calorimeter, suitable for detecting rates of heat production of the order of 1 mcal/h in about 2*3 ml. fluid, is described. Measurements have been made with it of the anaerobic heat production of bull spermatozoa in semen. The result, for the first hour, 220+ 15 mcal/109 live spermatozoa/h at 37° C, is consistent with the hypothesis that, in the first hour of incubation, the heat produc...
