This study was carried out to investigate whether cafeteria feeding affects behaviour of newborn milk fed dairy calves. Twenty Holstein Friesian calves were divided into two treatment groups single (TMR) and cafeteria feeding. Each calf was observed once a week for a period of 1 h at 5 min intervals at different times of a day after the initiation of daily feeding to monitor eating, ruminating, drinking, licking objects, playing, resting, body care and idle standing activities. The proportional count of eating, ruminating, drinking, licking objects, playing, resting, body care and idle standing were determined as 5.33, 6.52; 5.56, 8.89; 1.36, 1.09; 5.61, 5.14; 2.19, 1.60; 64.00, 62.58; 2.89, 3.59, 12.82 and 10.14%, respective to feeding systems TMR and cafeteria. There were not any statistically significant difference between cafeteria and TMR calves with respect to growth performance and blood parameters, except urea concentration, which was higher in cafeteria calves. In conclusion, cafeteria feeding increased welfare status of calf by decreasing idle standing behaviour and increasing body care without affecting growth performance significantly. Also, pre-ruminant calves in cafeteria feeding are able to make their own diet, more nitrogenous and less fibrous, as more appropriate to their digestive physiology. |

This study was planned to investigate the effect of aditional
lyzozyme to milk on growth performances of Holstein calves. About 15 female
and 18 male Holstein calves were used in this study. Between day 4 and 60, calves
were fed with whole milk from a pail twice a day such that each calf received
228 L whole milk (4 L day-1) over the whole experiment. All calves
were fed ad libitum with calf starter along with alfalfa hay. Calves
was fed with milk which is additional (10 mg L-1) lysozyme during
milk fed period. During 0-35 days period of the experiment, lysozyme supplementation
decreased daily gain and increased feed to gain ratio (p<0.05) and male calve
had higher daily gain, feed intake and better feed to gain ratio in the same
period (p<0.01). The effects of lysozyme and gender on daily gain and feed
to gain ratio have disappeared during 35-60 days period. Lysozyme decreased
feed intake (p<0.05) during 35-60 days of experiment. Similarly overall feed
intake, daily gain and feed to gain ratio were not affected by lysozyme (p>0.05).
Male calve had higher daily gain and weaning weight and lower feed to gain ratio
than female calve throughout the study (p<0.05). Lysozyme x gender interaction
affected feed intake in all experimental period and male receiving control diet
had higher feed intake than female but lysozyme supplemented male calves had
lower feed intake than female ones (p<0.05). The results revealed that lysozyme
may deteriorate of adaptation of the microflora of the gastrointestinal system
of 5 weeks old calves and be tended to decrease diarrhea cases during preweaning
period. |

The study was conducted to determine the effect of probiotic based on Lactobacillus sp. on performance and health status of Holstein male calves. 12 (3 days old) calves with average initial live weight 35 kg were assigned to the control and the group with probiotics applies. All calves were weaned at 60th day. Twice daily, during the time period till weaning they consumed 228 whole milk. Calves of probiotic group received 2 g probiotic daily with the morning milk. The results showed that there were no differences in daily gain, roughage, concentrate or total feed intake, feed to gain ratio and weaning weight. Calves fed with probiotic were healthier than the control calves. Three calves from control group and one calf from probiotic group were died from scour and/or bloat. In respect to diarrhea and bloat cases, probiotic group was superior to the control. It would be concluded that the probiotic administration before weaning could improve calves health and decrease mortality and veterinary cost. |
