The aim of this study was to explain the birth season effect on Hereford bulls fattening results. The research was made within the project ‘Baltic Grassland Beef’ framework in years 2015 and 2016. Data about 41 Herford purebred bull was used in the research, grown in different farms of Latvia. Bulls were slaughtered in certified slaughterhouse ‘Agaras’ (Lithuania). The average birth weight of the Hereford breed bulls was in border from 42.9 – 45.0 kg. The lowest birth weight was on spring season born bulls – 42.9 kg, but the highest on winter season born bulls - 45.0. Average realization age of bull’s, in the research groups, was on range from 567 days to 661 days. Bulls born on autumn and winter before slaughtering were significantly older, respectively 661 and 655 days with live weight of 519.9 kg un 542.1 kg. On spring born bulls with age 600 days reached the biggest live weight – 542.0 kg, respectively these group bulls average daily weight gain from birth to slaughter per day was the biggest among all the groups – 831.9 g. The highest slaughter weight showed on autumn and winter seasons born bulls, respectively 275.5 kg and 274.8 kg. In the research groups on different seasons born bulls conformation score was from points 2.4 to 2.6. All the bull’s carcass in the research groups were evaluated as 2nd and 3rd fat class. between the age before slaughter and average daily weight gain from birth to slaughter there is an important negative correlation (from r = -0.858 to = -0.977, p<0.05), except on spring season born bulls.

The aim of this work was to analyze the growth abilities of bull and heifer calves (n = 190) of the Charolais breed calved in one herd from 2006 to 2011. The evaluation was carried out during the period of calf raising, focusing to the effects of sex, parity and the mating method on live birth weight (BLW) and the live weight at 120 (LW120), 210 (LW210) and 365 (LW365) days of life, as well as the average daily weight gain reached by the age of 120 (G120), 210 (G210), and 365 (G365) days. Statistical analysis was carried out with the use of the SAS 9.3 program. The effect of sex on the live weight and average daily weight gain was statistically significant on the level of P < 0.01 always in favour of the bull calves (BLW +3.05 kg, LW120 +29.35 kg, LW210 +36.98 kg, and LW365 +117.23 kg). The lowest live birth weight was detected in the calves of primiparous cows (BLW = 45.46 kg; P < 0.01). The higher parity, the higher live birth weight was determined, with maximum values in cows from the fourth calving. The trends were similar in live weight at 120, 210 and 365 days of age, when significance level was P < 0.05. The parity effect on the average daily weight gain (G120, G210 a G365) was statistically insignificant (P > 0.05). The effect of embryo transfer (ET) and other commonly used reproduction methods (insemination and natural mating, AI/PP) was evaluated as well as. The calves born after embryo transfer showed a significantly (P < 0.01) higher the live birth weight as well as weight at different ages (BLW +5.85 kg, LW120 +18.15 kg, LW210 +22.94 kg and LW365 +35.43 kg), and G120 only (+100 g×day−1; P < 0.05). These results pointed the suitability of using the biotechnological reproduction methods, especially in relation to the total weight of the reared and fattened animals.

The effect of piggery temperature on daily live-weight gain of triple cross Large White-Duroc pigs was studied. Weaning rate and fattening completion rates were similar among piglets born in different seasons of the year but the average daily weight gain was slower during the early (20 to 40 kg live weight) and intermediate (40 to 60 kg live weight) periods of fattening in the autumn-born group (T < 0·05) whilst during the late period (60 to 80 kg live weight) slower growth rates were found in the summer- and winter-born groups (P > 0·05). In the intermediate period the fastest growth rates (900 g/day) were recorded at piggery temperatures of 16 to 20°C. In the same period the slowest growth rates (602 g/day) were recorded at temperatures of 8°C or lower and at 24°C or higher. The daily live-weight gain during the intermediate period was shown to be related to piggery temperature in a curvilinear manner according to the equation Y = −2·48x2 + 90·44x + 25·37.

The results of the replacement heifers of the Simmental breed, related to milk and meat producing bred types, in the post-natal ontogeny are represented. Practically no difference in the live birth weight indexes between the heifer-daughters of the bull Imago 9371649727 (Redad's line) was found out. Similar result was observed between the heifer-daughters of the bull Vickht 932375771 (Horrora's line). The live weight was high enough which is typical for the Simmental Combined Breed. Heifers of the both lines exceeded the breed Standart in their live-weight. However, the trend of higher live-weight was demonstrated by the heifers in the Redad¢s line during the research period. The most expressed difference of the live-weight between the heifers of the both lines was demonstrated by the heifers from the Redad's line at the age of 18 months. Their live-weight was 410,3 kg or more. It was 23,6 kg (6,1 %, p≤0,01) heavier in comparison with the heifers in Horrora's line and exceed the breed standards by 30,3 kg (7,9 %). It was figured out that the average daily weight gain was higher in the heifers from the Redad¢s line. At the age of 13-18 months and 0-18 months the heifers in the Redad's line exceed heifers in the Horrora's line by 15,8 % (p≤0,001, p≤0,01) and 6,8 % accordingly. The heifers of the both lines have strong structure, well-developed skeleton and muscles. They are compact, proportionally developed animals with wide chest and strong limbs. But the heifers of the Redad's had bigger torso diameter and at the age of 18 months were characterized by the greater high at withers, by the oblique body line (p≤0,01, p≤0,05), and also by the bigger chest girth between the shoueder blades (p≤0,01). There were no other differences in torso measurement between the heifers from the both lines. The leggy index naturally decreases with age. Slight increase in the mass index and in exterior is observed in heifers from the Horrora's line at the age of 18 months.

A 42-day feeding trial was conducted to investigate the performance characteristics and cost benefit of feeding weaner rabbits cashew nut residue (CNR) based diets. Three dietary treatments containing: 0.10 and 20% CNR at the expense of maize on a weight for weight basis were used. Eighteen weaner rabbits (mixed breeds and sexes) were randomly divided into three groups of six rabbits each in a completely randomized design (CRD). The average daily weight gain, average daily feed intake and feed conversion ratio were not significantly influenced (P>0.05) by the dietary treatments. But rabbits fed 10% CNR based diet had the highest values for average daily weight gain and average daily feed intake while rabbits fed the control diet (0% CNR) had the least value for feed conversion ratio. No mortality was recorded for all the dietary treatments. The feed cost/kg diet (₦), feed cost/kg live weight gain (₦/kg) and cost of feed consumed/day (₦) decreased steadily with increasing level of cashew nut residue meal. The saving on feed cost (%) was not significantly affected (P>0.05) by the dietary treatments, but increased across the groups. However, the saving on feed to produce 1kg live weight was significantly (P<0.05) influenced by the CNR based diets. Rabbits fed 10% CNR based diet had the highest value of 9.66% than their counterparts fed other diets. It is concluded that cashew nut residue could be incorporated into rabbit diet at 10% without compromising the performance

Performance Traits

Growth and reproductive performance traits are traits of economic importance for sheep selection and productivity improvement interventions. This study aimed at comparative evaluation of growth and reproductive performance traits of sheep in the highland and lowland agro-ecologies of northwestern Ethiopia. Data on growth performance traits were collected from 144 Washera (78 males and 66 females) lambs and 72 Gumuz (37 males and 35 females) lambs. Data on reproductive performance traits were collected from 260 Washera (130 rams and 130 ewes) sheep and 150 Gumuz (75 rams and 75 ewes) sheep. General linear model univariate procedure was employed to analyze the collected data. Breed, the interaction effect between breed and season of birth as well as the interaction effect between breed and type of birth all exerted very high significant effect (P<0.001) on live weight at all age groups. Breed type affected pre-weaning average daily weight gain significantly (P<0.01). Pre-weaning average daily weight gain of Washera (70 g/day) was found much better performance than 60 g/day of Gumuz. Breed type exerts significant (P<0.05) effect on age at first lambing, lambing interval, annual reproductive rate and number of lambs born per ewe life time. Average age at first lambing and lambing interval of Washera sheep were 11.69 months and 9.27 months, respectively. The corresponding values for Gumuz sheep were 12.51 months and 10.43 months, respectively. Production and reproduction performance values of traits varied across the two breeds and sexes as well. These values can be used to set up breeding objectives or goals for selective breeding of sheep giving special emphasis to growth traits believed to have medium heritability values.

In the Sverdlovsk region Holsteinized Black Pied cattle of the Ural type are bred which are represented by large, highly productive animals with a high genetic potential for productivity. Great importance is attached to the rearing replacement calves. The aim of the study was to study the dynamics of the live weight of replacement heifers from different seed bulls during rearing and its dependency on the age of the first insemination. The highest average daily weight gains were in the dairy period of heifers development, they ranged from 989 g for the daughters of the bull Thunderline to 1054 g for their peers from the bull Maximum. There were also high average daily gains during this period when rearing heifers from the bull Renigend. In the second period of rearing from 6 to 10 months of age there was a decrease in the average daily weight gain in all groups. Heifers from different seed bulls reach the required live weight for the first insemination at different ages. Maximum’s daughters, which had the weight of 399.4 kg at the age of 12.9 months. reached the required live weight most quickly. Their peers from other seed bulls reached the aforementioned live weight only at the age of 13.7 months.

The aim of the study was to evaluate the growth rate and selected carcass and meat quality parameters in bulls fed a high-grain diet and to compare the results with those obtained in bulls fed a diet based on preserved roughage. The trial included 18 Czech-Pied bulls fed a diet with a high proportion of concentrated feed and 18 Czech-Pied bulls fed a diet based on maize silage, used as a control group. The trial was launched after the weaning of calves. During the fattening period, live weight and average daily weight gain were monitored. The bulls were slaughtered at the live weight of 550–600 kg, the mean age at slaughter was 473 days for the high-grain diet group and 474 days for the control group. The carcasses were classified to SEUROP quality grades, and carcass gain and dressing percentage were calculated. Samples of <I>m. longissimus pars thoracis</I> were taken from five bulls in each group to examine selected meat quality parameters. In the period from weaning to slaughter the high-grain diet bulls and the control bulls achieved the average daily weight gain of 1.29 kg and 1.21 kg, respectively. Differences between the groups were not significant. The high-grain diet group showed higher average carcass weight and higher carcass weight gain, differences between the groups were not significant, either. As to meat quality parameters under study, a significant difference was found only in meat lightness (L*), with the mean value in the high-grain diet group being significantly (<I>P</I> ≤ 0.01) lower than in the control group. The other meat quality parameters did not show any significant differences between the groups. In this study, the high-grain diet gave similar performance as the maize silage-based diet in fattening bulls. The high-grain diet group and control group showed comparable average daily weight gain and selected carcass and meat quality parameters.

This study was conducted to compare the growth and economic performances between Swamp and Murrah crossbred buffaloes. The records of 108 Swamp and 276 Murrah crossbred buffaloes born between January 2010 and December 2015 were used in this study. The farm was practicing an extensive grazing system without supplementation from January 2010 to December 2011 (pre-intervention) and a new implementation of supplement in the feeding regime from January 2012 to December 2015 (post-intervention). The birth, weaning, and body weight at three monthly intervals, number of calves born, and mortality rate of calves at different years and during pre- and post-intervention were analyzed using a general linear model procedure. The interventions in 2012 had a positive effect on increasing the number of calves born for both breeds, average birth weight, economic performance, and reduce mortality calf rate. As a result, the birth weight of Murrah crossbred buffaloes was higher (36.63 ± 0.50 kg) than Swamp buffaloes (34.69 ± 0.40 kg) (p < 0.05). The average pre-weaning daily weight gain for Swamp and Murrah crossbred buffaloes was 0.73 and 0.98 kg/day (p < 0.05), while the average post-weaning daily weight gain was 0.39 and 0.44 kg/day, respectively (p < 0.05). The Swamp and Murrah crossbred buffaloes achieved the targeted market weight of 250 kg at 18 and 15 months old, respectively, while the targeted breeding weight of 385 kg was achieved at 30 and 26 months old, respectively. In this farm, on average a total of 64 calves were born yearly, with the ratio number of born calves per number of mated dams recorded higher in Murrah crossbred buffaloes as compared to Swamp buffalo (0.64 vs. 0.37) (p < 0.05). Furthermore, the average number of calves born in the post-intervention period (January 2012–December 2015) was significantly higher than in the pre-intervention period (January 2010–December 2011), respectively (Swamp: 23 vs. 8 and Murrah crossbred: 53 vs. 31, respectively) (p < 0.05). Partial budget method was used to estimate the net gain or loss between the two breeds. The average annual revenue was 2304.14 MYR (566.13 USD) for Swamp buffaloes and 4531.50 MYR (1113.39 USD) for Murrah crossbred buffaloes. The average annual cost saving was 340.02 MYR (83.54 USD) for Swamp and 215.75 MYR (53.01 USD) for Murrah crossbred buffaloes. On the other hand, annual added cost was 84.95 MYR (20.87 USD) for Swamp and 96.76 MYR (23.77 USD) for Murrah crossbred buffaloes. Therefore, the annual net benefit was 2559.21 MYR (628.80 USD) for Swamp and 4650.49 MYR (1142.63 USD) for Murrah crossbred buffaloes. As a conclusion, this study had shown that the higher average daily weight gain contributes to better cost savings, as shown by the crossbred buffaloes.

The rams of the Askanian meat-wool breed, grown and kept in the conditions of the steppe zone of the south of Ukraine, were investigated for their adaptive capacity and adaptation to the conditions of the lowland regions of Zakarpattja. It was found that the physiological response of the rams to the maximum air temperature was characterized by a slight increase in body temperature and pulse, and a significant increase in respiratory rate per 1 minute. The good adaptive properties of the Askanian meat and wool breed rams are indicated by the high breeding capacity of ewes, at 97%, in both farms. The ewes of the breed prekos with a live weight of 55.9–58.9 kg were involved in the breeding process, and the Askanian rams with a live weight of 93.3–95.1 kg. It was studied the influence of crossbred crossing of crossbred Askanian sheep of meat and wool breed on the development of productive and reproductive features of Zakarpattja sheep ewes of the breed prekos with the purpose of obtaining mixed breeds with improved economic performance. It is proven by theory and practice that one of the main criteria for the rational management of sheep breeding in modern conditions is the study of individual features of growth and development of young sheep. In a market economy, increasing the meat productivity of sheep is an important factor that determines the level of economic efficiency of the industry. Obtained progeny at the age of 4–8 months had a higher intensity of growth. Thus, the average daily weight gain of lambs in the control group was 234 g, and experimental — 265 g, which is 11.3% more than in the control. The average daily weight gain of the bright control group was 205 g, and the experimental one — 244 g, which is 11.9% more than in the control group. At the age of 8 months, the fat mass of slaughtered animals ranged from 32–36 kg and the carcass weight was 15–18 kg with good fat irrigation. The classification of sheep carcasses by fat irrigation according to the EUROP system corresponded to the average level of coverage of carcasses with fat, that is, the whole carcass was covered with a thin layer of fat, at the base of the tail — small accumulations of fat, the kidneys partially or completely covered with a thin layer of fat, with a slight fatty water between visible intercostal muscles .The balanced feeding of experimental animals had a positive effect on the increase in live birth weight and their viability. The minimum selection parameters of breeding sheep ewes, which are involved in the breeding process, are also set for obtaining animals with high multi-farrowing and combined productivity.
