Abstract Objectives of this study were to evaluate birth weight (BW), weaning weight (WW), and average daily weight gain (ADG) of female calves carrying the SLICK1 allele, i.e., the slick gene. Holstein cows in four dairy farms located in central California were inseminated with semen from two heterozygous slick Holstein sires to produce slick and non-slick calves. Calves were born during the cool season (November 2019-March 2020). BW was recorded for 125 calves in four farms within 24 h of birth; WW was recorded for 92 calves in three farms within one week of weaning. Weaning age was recorded at day of weighing. ADG was calculated as the weight difference between birth and weaning divided by days of age at weaning. Only female calves were used in the analysis. Statistical analyses were performed using the GLIMMIX procedure of SAS version 9.4. The model for BW included the effects of genotype, farm, sire, and the interaction between genotype and farm. The model for WW and ADG included the effects of BW, genotype, farm, weaning age, sire, and interaction between genotype and farm. Significant effects were considered as those with P < 0.05. There was no difference in BW or WW between genotypes (BW: slick=40.1 ± 0.7 vs non-slick=39.7 ± 0.6 kg; P = 0.7 and WW: slick=82.5 ± 2.8 vs non-slick=80.9 ± 2.8 kg; P = 0.6). The mean age at weaning was 64.8 ± 0.4 and was similar for both genotype groups (P = 0.8). As a result, ADG was similar between genotypes (P = 0.7). There was a main effect of farm on BW, WW and ADG. Results indicate that slick heifer calves born in the cool season perform similarly to non-slick calves in regards to birth weight, average daily weight gain, and weaning weight.

Holstein Calves

The present study was conducted to determine some environmental factors affecting birth weight, weaning weight and daily live weight gain of Holstein calves of a livestock facility in Izmir, Turkey. The data on 2091 calves born between the years 2005-2010 were used to assess the relevant parameters. Effects of calving year, calving month, calf gender and the interaction between calving year and calving month on calves’ birth weights were highly significant. The overall mean of birth weights was 39.6±0.15 kg. In addition, effects of calving year, calving month, gender, birth weight, weaning age, calving year x calving month, calving year x gender and calving year x calving month x gender interactions on weaning weight (WW) and daily live weight gain (DLWG) were highly significant. The overall means of WW and DLWG were respectively found to be 79.7±0.20 kg and 525±2.5 g. A one kilogram increase in birth weight resulted in an increase of 0.89 kg in weaning weight and a decrease of 1.26 g in daily live weight gain. Prenatal temperature-humidity index (THI) affected birth weight of calves (R2=0.67). Increasing THI from 50 to 80 resulted in 3.8 kg decrease in birth weight.

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.

In this study, we compared the growth and survival characteristics of Romanov × Morkaraman (F1 Rom), Romanov × F1 Romanov (G1 Rom) and Charollais × F1 Romanov (Charom) crossbreed lambs weaning weight at different ages. After birth, from three genotypes lambs were weaned at two different ages of 50 and 75 days and growth performance after weaning was examined at 120 days of age. The effect of three different genotypes and birth type on birth weight was very important, and sex effect was insignificant. In weaning weight, only the effect of birth type was found to be significant. Lamb birth and weaning weights were in Charom, F1 Rom, G1 Rom lambs, 3.38-15.28; 3.98-15.04; 3.21-15.55 kg, respectively. The type of birth showed variation in the birth weight of the lamb and the decrease in lamb birth weights (Single: 4.19 kg: Twin: 3.42 kg; Triplet: 3.15 kg and Quadrature: 2.88 kg) was observed as the number of offspring increased. The effect of the birth type on weaning weights was similar in single and triplet. Single-born lambs have higher weaning weights than those of twins and quadruplets. Average daily live weight gain (ADG) from weaning in single lambs, 247.37 g were found higher than twin (190.67 g), triplets (201.44 g) and quadruplets (178.57 g). The effect of weaning age was insignificant on weaning weights. The first month weight after weaning, effect of the genotype of the lamb, the birth type and the sex were insignificant; but effect of weaning age was significant weaning weights and first month after weaning weights the ADG. The late weaned lambs had higher next first month live weight (18.62-17.89 kg) and ADG (179.45-81.32 g). The live weights of the lambs on the 120 days were similar and none of the factors investigated were found to be effective.

Objective: To evaluate intermittent Kangaroo Mother Care (KMC) with additional opportunities to breastfeed on weight gain of low birth weight (LBW) neonates with delayed weight gain. Methods: 40 LBW neonates were followed to see whether KMC with additional opportunities to breastfeed improved weight gain. Results: In the KMC group, the mean age of regaining birth weight was significantly less (15.68 vs. 24.56 days) and the average daily weight gain was significantly higher (22.09 vs. 10.39 g, p < .001) than controls. Conclusion: KMC with additional opportunities to breastfeed was found to be an effective intervention for LBWs with delayed weight gain and should be considered to be an effective strategy.

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&amp;amp;lt;0.05), except on spring season born bulls.

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.

The majority of lamb losses occur within the first two weeks of life, with cold stress being a major cause of lamb morbidity and mortality. This study investigated the effect of insulating lamb jackets on newborn lambs. One hundred and four newborn lambs were randomly allocated by birth date to two treatment groups, (a) non-jacketed (n = 52) or (b) jacketed (n = 52), for fourteen days after birth. The live weights of lambs were recorded regularly up to 21 days, and average daily weight gains were calculated from these data. For the first two days after recruitment to the study, surface and body temperatures of lambs were also recorded. The jackets significantly increased the lambs’ surface temperatures, providing a warmer microclimate and reduced cold stress for jacketed lambs. There was no significant effect of the insulating jackets on estimated body temperatures, live weights or average daily weight gain of the lambs in this study. There were no detrimental effects of the jackets, and no rejection of lambs occurred.

A study was conducted to determine the efficacy of three most commonly used growth promoters from different pharmaceutical companies on growth performance of hybrid walking catfish (Clarias batrachus × Clarias gariepinus). The experiment was done in the wet laboratory of the Department of Aquaculture, BAU, Mymensingh, with a total of 10 aquaria and 160 fish having mean initial weight of 6.3 ± 0.48 g. The three growth promoters, “Charger gel” from Fishtech (BD) Ltd., “Growth gel” from Advance Agrotech (BD) Ltd. and “Hepaprotect-aqua” from Renata Animal health Ltd., were used in separate nine (9) aquaria at recommended, lower dose and higher dose respectively. One aquarium was used as control (diet without any growth promoter). The fish were fed with paragon nursery floating feed at 20% of body weight in each aquarium for 28 days. Doses of Charger gel were given as 80, 60 and 100 mg/20 g feed/day, that of Growth gel, 0.14, 0.12 and 0.16 ml/20 g feed/day and of Hepaprotect-aqua, 30, 15 and 50 mg/20 g feed/day. Re-circulatory system was used throughout the experimental period. By applying recommended, lower and higher dose of “Charger gel”, mean final weights were found as 23.0, 21.9 and 35.9 g; average daily weight gain as 0.60, 0.56 and 1.06 g and specific growth rate (SGR) as 2.01, 1.93 and 2.70% respectively. For “Growth gel”, mean final weights were found as 22.8, 17.3 and 31.1 g; average daily weight gain as 0.59, 0.39 and 0.88 g and SGR as 1.99, 1.57 and 2.48 % respectively. For “Hepaprotect-aqua”, mean final weights were found as 24.2, 17.5 and 28.2 g; average daily weight gain as 0.64, 0.40 and 0.78 g and SGR as 2.09, 1.58 and 2.32% respectively. In all the cases survival rates were 100%. All the three growth promoters showed better results at their higher doses in comparison to their results in lower and recommended doses. However, in average Charger gel showed the best result than the other two growth promoters. This information on the efficacy study of growth promoters needs to be disseminated to the farmers for improved fish production.Asian J. Med. Biol. Res. March 2017, 3(1): 103-108
