This study was conducted to compare Central Anatolian Merino (CAM) and Malya sheep under intensive conditions in terms of reproductive traits, birth and weaning weights, fattening performance, and some fleece characteristics. In this study, 840 CAM and 194 Malya ewes were used for the comparison of reproductive performance, whereas 740 and 211 lambs were used to compare growth traits between the two breeds. Additionally, the fattening performance of 61 CAM and 68 Malya lambs were compared. Finally, for the comparison of wool quality traits, 94 CAM and 90 Malya lambs were used. The lambs were kept together with the sheep that gave birth to them for 10 days. After this period, lambs were given lamb starter feed, alfalfa hay, and vetch hay in addition to milk. When lambs reached 40 days old, they were taken to the pasture with the sheep. In this period, pasture grass, growing lamb concentrate feed, alfalfa hay, and vetch hay were given in addition to milk. Lambs were weaned when they reached an average age of 90 days, and their live weights were determined. A determined number of lambs was selected from weaned male lambs. For these animals, in the fattening period, barley, alfalfa hay, vetch hay, meadow hay, and lentil straw were provided ad libitum in addition to 400 g/day/head of fattening feed. This study indicated that birth rate was better for CAM sheep than for Malya sheep. However, Malya lambs may have more advantages than CAM lambs in terms of survival and fattening performance. Although birth weight was higher for Malya sheep than for CAM sheep, the opposite result was observed for the weaning weight. The beginning weights of fattened male lambs were higher for CAM lambs than for Malya lambs, but the ending weights of both fattened groups were similar.
The aim of this study was to determine the quality of potato pulp silage (PPS) prepared with wheat bran and barley straw and the effects of the substituting corn silage with potato pulp silage at differing levels in dairy cows on milk yield, composition and rumen volatile fatty acid (VFA). The study consisted of two experiments. Nutrient contents, fermentation parameters, in situ organic matter (OM) and starch degradabilities, in vitro digestibility (IVD) and metabolic energy (ME) content of PPS were determined in the first experiment. The effects of substituting corn silage with potato pulp silage at 0%, 15%, 30% and 45% in the diet of lactating 12 dairy cows on feed intake, milk yield, milk components, rumen fermentation parameters were evaluated in the second experiment. While dry matter (DM), OM and crude protein (CP) contents, pH of silages were statistically similar, starch content, in vitro organic matter digestibility (IVOMD), ME, net energy lactation (NE L) , and lactic acid values were significantly higher in PPS compared with corn silage (P<0.05). Organic matter intake, milk yield, the composition of milk, post-feeding pH and total VFA levels of ruminal fluid at all sampling hours were similar among the dairy cows (P>0.05). It was concluded that; PPS prepared with wheat bran and straw had a very good silage quality and were even better than corn silage (control). Substitution of corn silage with PPS up to 45% did not cause any negative effects on rumen fermentation parameters and can be safely substituted with corn silage up to 45% in dairy cow diets.
The purpose of this study was to compare the fattening performance of some cattle breeds under same care and feeding condition, which were imported to a private farm in Turkey. Approximately eight months old male Angus (AN) (n=12), Charolais (CH) (n=33), Limousine (LM) (n=40) and Simmental (SM) (n=9) breeds were imported from Ireland to a private farm in Çorum. Least squares means for AN, CH, LM and SM, respectively, for the elapsed time (ET) of the breeds from the beginning of feeding until slaughter were 181.42±8.07, 181.30±4.87, 186.15±4.42, and 194.78±9.32 days; for the initial live weights (IW) at the beginning of fattening period were 404.42±11.26, 418.70±6.79, 389.00±6.17 and 430.56±13.00 kg; for the live weights (LWS) at the time of slaughter were 616.78±14.29, 625.64±8.80, 636.00±8.13 ve 631.97±16.84 kg; for the average daily live weight gains (ADLWG) were 1.17±0.06, 1.23±0.04, 1.23±0.03 and 1.16±0.07 kg; for the hot carcass weights (HCW) were 355.45±10.20, 362.76±6.28, 385.15±5.80 and 368.98±12.02 kg; for the dressing percentages (DP) of the breeds were 57.47±0.95, 58.09±0.58, 60.64±0.54 ve 58.48±1.12 %. Mean consumption of DM, OM, NDF, ADF and CP were 11.43, 11.18, 5.03, 2.63 and 1.55 kg. ET (p=0.643), LWS (p=0.653), ADLWG (p=0.600), FE (p=0.871) and HCW (p=0.389) were not statistically different whereas IW (p=0.003) and DP (p=0.005) were statistically different for the breeds. The IW of Limousine was lower than Charolais (p=0.009) and Simmental (p=0.025) whereas Limousine had better performance for the DP than did Angus (p=0.027) and Charolais (p=0.014).
