“…This agreed with results recorded by Zavadilová and Štípková (2103) who that there is a lower probability to show conceive for cows in class over 33 months of AFC. This disagreed with results recorded by Gurmessa and Melaku (2012) and Pratap et al (2014) who found that milk yield did not show significant variation in different age and parity groups and this may be due to the fact that the farm of their study was established only two years ago that cows are fairly young and calving was not much. But, on our study different ages represented and occurred complete development of mammary gland tissues by successive parturition.…”

Key words:Ingestive Behaviour, Suckling Disorders, cow This study was carried out during the period from February 2016 to February 2017 on 100 Friesian dairy cows aged (3-7 years old) of different parities belonged to private dairy farm which locate at Hehia city at Sharkiya governorate. The aim of the present study was to investigate the effect of age of dairy cows on their ingestive behaviour, suckling disorders, productive performance, milk constituents and serum cortisol level of Friesian dairy cows. The results were revealed that, on ingestive behaviour, the age of 4 th years old was the highest significant (P<0.05) feeding time, feed frequency, drinking time, drinking frequency, rumination time and rumination frequency (399.9 min, 87.2, 18.6 min, 142.9, 52.2 min and 37.2); respectively. The mutual suckling time and frequency were at highest significant level (P<0.05) at early life of age (three years), while the tongue rolling, ear and nose suckling were increased with age. On productive traits at different ages studied, the 7 years old age group was the highest significant (P<0.05) at parity (4.66). Meanwhile, the 6 years old age group was the highest significant (P<0.05) at milk production and day in milk (8077.5 kg and 300.0 day; respectively). Dry period showed non significant results between the different ages. The 6 th years of age was the highest significant (P<0.05) cortisol level (2.80 ng/mL) than other ages. Correlations between productive and ingestive behaviour traits for all ages studied showed positive high significant estimates (P<0.05) at parity with drinking frequency, milk production with day in milk , feeding time with drinking frequency and feeding time with rumination time. Concerning the effect of age on the milk components, the SNF and protein components of the milk were significantly lower (P<0.05) in young than adult cows (from 3 years to 7 years), however, significant difference was not observed in fat, lactose and pH of the milk between age groups.

“…The increase in protein and lactose percent would have resulted in significant increase in SNF in pregnant animals. Similar results were reported by Gurmessa and Melaku (2012) and Pratap et al (2014) who observed a significant increase in SNF, protein and lactose contents of the milk during pregnancy.…”

“…Milk yield was significantly (p<0.05) lower whereas SNF and lactose percent were significantly (p<0.05) higher in pregnant animals when compared to non-pregnant animals. A decline in milk yield with pregnancy has also been reported by Akers (2002) and Pratap et al (2014).…”
