In the second experiment, a total of twenty-four (n=24) Dohne Merino rams of about 8 to 9 months old, weighing 19.8 ± 0.43 kg were confined in individual pens for a period of 100 days. The rams were subjected to four varying inclusion levels of fossil shell flour (0g/kg, 20g/kg, 40g/kg and 60g/kg. Water and feed intake were recorded throughout the period of successive feeding. Blood samples were collected on days 0, 45 and 90. The parameters studied included the average daily water intake (ADWI), average feed intake (ADFI), skin temperature (ST), respiration rate (RR), pulse rate (PR), rectal temperature (RT), total plasma protein (TPP), mean corpuscular hemoglobin concentration (MCHC) and mean corpuscular volume (MCV). The inclusion levels of FSF affected both the ADWI and ADFI, showing a high-water intake and feed intake in rams subjected to 40g/kg of FSF followed by 60g FSF/kg, 20g FSF/kg and 0g FSF/kg (P< 0.01) respectively. All the physiological parameters ST, RT, RR, HR and PR decreased with an increase in the inclusion levels of FSF (P< 0.01). The TPP increased as the levels of FSF increases (P< 0.01). The MCHC was low in rams subjected to 60g FSF/kg and in 0g to 40g FSF/kg TPP increases as levels of FSF increases (P< 0.01). This study concluded that supplementing with various inclusion levels of FSF had a positive effect on feed preference. The FSF also showed the ability to mitigate heat stress in Dohne Merino rams.]]> Thu 07 Jul 2022 11:04:31 SAST ]]>
