Increasing concern about some animal production systems has placed considerable value on humanitarian breeding systems, aimed at ensuring animal welfare and comfort. Raising calves is one of the most important stages in a milk production system. This study aimed to evaluate and compare the performance of Holstein dairy calves raised by two farming systems: conventional individual (CI) and collective with automatic calf feeder (CACF). Fourteen, 15-day-old Holstein dairy calves having an average initial body weight of 40 kg, were used. The animals were distributed in a completely randomized design with seven animals per treatment. The variables evaluated were the milk and feed intake, body weight, hip height, thoracic circumference and daily weight gain. The average milk intake was lower in the CACF (3.5 L animal-1 day-1) than CI (5.1 L animal-1 day-1) system. However, the feed intake was higher in the CACF (1.205 kg animal-1 day-1) compared to CI (0.910 kg animal-1 day-1) system. Body weight, thoracic circumference, hip height and daily weight gain were similar between the two systems. The CACF raised calves had a higher concentrate intake and lower milk intake than the calves raised under the CI system.

One hundred and twenty (120) 16 weeks old White Leghorn layer breeds were used for the study. The objective of the study was to determine effect of photoperiod on layer chicken. The research was carried out at the Poultry Section of the Animal farm of the Department of Animal Science Education, Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development, Mampong. Four treatments made up of 12 hours of light, 14 hours of light, 16 hours of light and 18 hours of light were used for the study. Each treatment was replicated three times with 10 birds per replicate in a Completely Randomized Design. Birds were exposed equally to common daylight and in the evenings, lights were turned on at specified periods. Growth parameters measured were initial body weight, daily feed intake, daily weight gain and final body weight. Egg traits measured were egg weight, albumen height, yolk color and yolk weight. The data collected were analyzed using General Linear Model procedure of Statistical Analysis System. Results from the study indicated that, varied photoperiod regimes had no significant (P>0.05) effect on initial body weight, daily feed intake but had significant (P<0.05) effect on daily weight gain and final body weight of growth traits. Photoperiod had no significant (P>0.05) effect on the egg characteristics of the white Leghorn layer bird. It was concluded from the study that, increasing photoperiod had no positive effect on growth and egg characteristics of the white Leghorn layer.

This study aims to determine the effect of fermented sago pulp in rations on performance (weight gain, feed consumption, feed conversion) and local sheep's income over feed cost (IOFC). This research was carried out in the community farms of Karang Rejo Village, Stabat District, Langkat Regency. This research started from March to June 2017. The design used was complete randomized design (RAL), with 4 treatment of 5 replications. Each replication consisted of 1 local sheep with an initial weight of 11.05 ± 0.56 kg. The treatment consisted of P1 (50% sago pulp without fermentation + forage), P2 (60% of sago pitch without fermentation + forage), P3 (50% fermented sago pulp + forage), and P4 (60% fermented sago pulp +). The observed variables were performance (body weight gain, feed consumption, feed conversion) and income over feed cost (IOFC). The results showed that the treatment of fermented sago pulp gave a very real effect (P <0.01) on daily weight gain. The mean of P1 = 33,05 g, P2 = 39,95 g, P3 = 46,57 g, P4 = 54,38g. The consumption of fermented sago pulp treatment has a real effect (P <0,01). With average P1 = 486,38 g, P2 = 548,68 g, P3 = 604,69 g, P4 = 671,11 gr. Against the conversion of fermented sago pulp fermentation treatment gave a real effect (P <0.05). With average P1 = 14.78, P2 = 13.90, P3 = 12.99, P4 = 12,49. IOFC the highest local sheep is Rp. 121.568 on treatment of P4 and IOFC lowest at treatment P1 equal to Rp.73.315. The conclusion of the research shows that the utilization of fermented sago pulp can increase body weight gain, feed consumption, local sheep feed conversion. P4 treatment economically has a better economic level than P1,P2 and P3.

The experiment was conducted to evaluate the effect of supplementing different levels of molasses and concentrates mix with a basal diet of cultivated pasture hay on intake, body weight and carcass quality of Afar sheep. Twenty four yearling Afar sheep, grouped in to four groups of six animals each in a randomized complete block design. The experiment consisted of four months feeding trial each group will receive the experimental feeds. Treatments were mixed concentrate + 20% inclusion molasses (T1), mixed concentrate + 15% inclusion molasses (T2), mixed concentrate + 10% inclusion molasses (T3) and 0% inclusion (T4). In this experiment with mean initial weight of 15.9±0.39 kg (mean ± SD), 16.2 ±0.41 kg, 16.3±0.42k.g and 16.1kg±0.42 respectively, were used in each treatment group. The experiment was consisted of 90 days of feeding trial followed by carcass evaluation. The concentrate mix were 2:1 (wheat bran and cotton seed cake) The CP content of the panicum antidotale hay, concentrate mix and molasses were 95g/kg DM, 252g/kg DM, and 38.4g/kg, respectively. Hay DM intake was did not differ (P<0.05) among all treatments. Average daily weight gain (ADG) was higher (P<0.05) for T2 (69.59g/kg) compared to other treatments. Hot carcass weight also higher (P<0.05) for T2 (14.41kg). Weight gains 12.31kg, 13.83kg, 11.25kg and 10.26kg for Tx1, Tx2, Tx3 and Tx4, respectively). All Carcass parameters gave advantage (P<0.01) to Tx2. From the present study, it can be concluded that Tx2 sheep performed better than Tx1, Tx3, and Tx4 in terms of body weight gain, Feed intake, and carcass parameters. Asian J. Med. Biol. Res.

The objective of study was to determine the effect of calf starter in the pre-weaning calves against the daily body weight gain. Twenty Ongole grade (PO) calves age of 1 month divided into 4 treatment groups of feed, 5 calves for each treatment. Treatment (P1) fed with extra soybean groats; (P2) soybean groats 50% + Gliricidia 50%; (P3) soybean groats 50%+ rice bran 50%; (P4) soybean groats 50%+ rejected bread 50%. Calf starter was given at age 1 month to 3 months. Observation was carried out on calves daily weight gain. This experiment was designed in Completely Randomized Design. Data was  analyzed by analysis of variance and continued Least Significant Difference Test. Statistical analysis showed that feed of (P <0.05) significantly affected the daily weight gain of the calves. Results of the study can be concluded that calf starter with soya groats provide the best daily weight gain of pre-weaning calf.

The objective of the current study was to examine the effects of mannan-oligosaccharides or inulin on HF dairy heifers’ starter feed intake and daily weight gain in farm situations. We measured these parameters across two experiments. In Trial 1 (T1), next to the control group, 15-15 HF heifers received MOS or inulin supplementation from 1st day of age to weaning. The amount of the supplementations changed according the calves’ age and the amount of milk replacer from 12 g to 24 g/calf/day. We measured the individual feed intake daily, the live weight at 0, 14, 21 and 60 days. In the second experiment (T2) we used 30 HF heifers also in three group (Control, MOS, Inulin) but we gave more from the experiment materials (28 g/calf/day MOS or Inulin). We started dosing the supplements with the colostrums feeding, and gave up on 14th day of age. We also measured the individual feed intake daily and the live body weight (BW) at 0, 14, 28, 42 and 56 days. The treatments in T1 did not cause significant differences in average feed intake, body weight and average daily weight gain. When the calves got the supplementation with colostrum too, the ADWG was significant lower in the group fed inulin than control and group fed MOS (P<0.05). We calculate the ADWG all of the experimental periods. From 0 to 14 day, and from 0 to 56 day the ADWG in inulin group was lower than control group, but the datas of group MOS did not differ from the others. Due to the distribution of the birth weights, the lower ADWG did not manifest in differences in body weight in other points of the experiments. We did not find an interaction between the treatments and the daily feed intake of calves. According with our measurements,
