Abstract Science has been searching for a long time for a reliable method for controlling the sex of mammalian offspring. Recently, the application of specific modern cellular methodologies has led to the development of a flow cytometric system capable of differentiating and separating living X- and Y-chromosome-bearing sperm cells in amounts suitable for AI and therefore, commercialization of this sexing technology. The aim of this work was to present the first results of heifers that introduce bovine AI with sex sorted semen, for the first time in Macedonia. Insemination with sex sorted cryopreserved semen (2×106 spermatozoa per dose) imported from the USA was done at two dairy farms in ZK Pelagonija. In total, 74 heifers (Holstein Friesian) were inseminated. Inseminations were carried out in a timely manner following a modified OvSynch protocol. During the insemination, the sperm was deposited into the uterine horn ipsi lateral to the ovary where a follicle larger than 1.6 cm was detected by means of transrectal ultrasound examination. Pregnancy was checked by ultrasound on day 30 after the insemination. Overall, the average pregnancy rate in both farms was 43,24% (40,54% and 45,95%, for farm 1 and farm 2, respectively). All pregnant heifers delivered their calves following a normal gestation length (274,3 days in average) and of the 32 born calves, 30 (93,75%) were female. In conclusion, since the first results from inseminations with sex-sorted semen in dairy heifers in Macedonia are very promising, the introduction of this technique may bring much benefit to the local dairy sector. Average pregnancy rate seems similar with results obtained following ‘regular’ inseminations, notwithstanding the relatively low number of spermatozoa per insemination dose. Due to the latter, we however recommend inseminations only to be carried out by experienced technicians followinga TAI protocol and ultrasound examinations of the ovaries prior to insemination.

Lizaso, G., Beriain, Ma. J., Horcada, A., Chasco, J. and Purroy, A. 2011. Effect of intended purpose (dairy/beef production) on beef quality. Can. J. Anim. Sci. 91: 97–102. Fifteen Pirenaica (beef) heifers and fifteen Holstein-Friesian (dairy) heifers were compared to consider the effect of intended purpose of the breed on meat quality. Animals were slaughtered at around 12.4 mo of age. Carcass weight was 247.6 kg for Pirenaica and 229.2 kg for Holstein-Friesian heifers. pH24hours, moisture, fat, protein, ash, water holding capacity, CIE L*a*b* and C* and H* values, collagen content, and shear force were determined in longissimus dorsi muscle. Sensory analysis of meat was performed to obtain the texture profile, scored by a trained taste panel. Sensorial differences of meat were mainly in relation to higher fat content observed in Holstein-Friesian (2.87%) vs. Pirenaica breed (1.82%) (P<0.01). Total and soluble collagen contents for the two breeds differed (P<0.01 and P<0.05, respectively) but did not result in different meat tenderness scores by taste panelists. Higher water-holding capacity in meat of Holstein-Friesian was observed (P<0.01). CIE L*a*b*, coordinates C* and H* values were not different between breeds. Sustained juiciness and oiliness were higher in Holstein-Friesian than Pirenaica (P<0.05 and P<0.01, respectively). Results suggest that beef characteristics of young heifers of dairy and beef breeds are similar with the exception of characteristics related to juiciness.

Effect Of Feeding

The objective of this study was to determine the effect of feeding two fermented total mixed ration (FTMR) on methane production in dairy heifers. Four Holstein Friesian dairy heifers with mean body weight (BW) of 301.1 ± 42.2 kg were used in a simple cross-over design trial. Treatments consisted of 2 FTMR formulated to yield either low (LMD) or high CH4 production (HMD). No differences were observed in dry matter intake (DMI; 6.49 and 6.19 kg/d), BW change (-3.37 and -7.25 kg), or DM digestibility (50.64 and 46.99%) between diets. Ruminal pH, total volatile fatty acids (TVFA) and molar proportions of acetate, propionate and butyrate were not different among diets. Concentrations of blood glucose were higher (P=0.05) for HMD compared with LMD at 2 h post feeding; however, blood urea nitrogen was not different. Methane emissions were 236.32 L/d for LMD and 273.70 L/d for HMD and not different. Feeding the FTMR differing in CH4 potential did not affect DMI, digestibility, ruminal TVFA production or molar proportions of VFAs in dairy heifers.

The purpose of this study was to examine the effects of supplementing milk replacer (MR) with aromatic oregano (Origanum onite L.) water on weaning age, performance during the pre- and post-weaning periods, immune systems, blood parameters and general health of 40 Holstein Friesian calves. The calves fed with oregano water (OW)-supplemented MR were weaned earlier than those in the Control group. There were no statistical differences in the liveweight and body measurements among the groups at the weaning age and post-weaning period. The feed intake of the calves fed with OW was higher than that of calves in the Control group in the pre-weaning period. The OW supplementation significantly increased the faecal firmness of calves (P < 0.05). It also decreased the number of E. coli, Coliforms and Enterobacteriaceae pathogens, but only the amount of Enterobacteriaceae was significantly decreased (P < 0.05). Non-pathogens, such as Lactic acid bacteria, were not affected by OW supplementation. The OW supplementation had no significant effect on hematologic and biochemical blood values. There was significant interaction between age and groups in gamma-glutamyl transpeptidase (P < 0.05). The immunoglobulins (IgA, IgG and IgM) values of calves were steadily higher than those of the calves in the Control group. The general health profiles of the calves improved. It can be concluded that MR containing 1–2% OW fed to calves in the early weaning period is a promising treatment to improve their wellbeing and shorten the weaning period.

Human Animal

Extensive research into human-animal interactions, particularly in the pig industry, has led to the proposal that high fear of humans, through a stress response, can limit an animal’s growth, reproduction and welfare (Hemsworth et al., 1993). In a recent study in the Australian dairy industry, a significant negative between-farm correlation was found between the avoidance of an experimenter by cows in a standard test and milk yield of the farm, suggesting that fear of humans may also have implications for the productivity of dairy cows (Breuer et al., 2000). The behaviour of stockpeople is a likely factor affecting fear of humans in dairy cows (Breuer et al., 2000). It was the aim of this experiment to investigate the effects of handling on the stress physiology and behaviour of dairy heifers.

Metabolic Hormone

Nutrition during the rearing period has significant effects on subsequent milk production and reproductive performance of dairy herd replacements. Carson et al. (2002) reported that heifers reared to calve down at 620 kg, in contrast to 540 kg live weight, produced 11% more milk, lost more weight and body condition score (BCS) post-calving and had a 30 day longer calving interval. This suggests that a higher BCS at calving and/or a greater rate of BCS loss during lactation appear to be correlated with poorer fertility. The objectives of this experiment were to investigate the effect of (1) diet composition during the rearing period and (2) live weight at first calving on body size and condition score changes during the first lactation and to assess linkages with metabolic hormone concentrations.
