Friesian Cows

The effect of time (morning or afternoon), intensity (three or four calves per cow), frequency Once or twice daily) and duration (1, 2, 4 or 8 weeks) of suckling on the performance of multiparous Friesian cows in early lactation was studied in four experiments. In each experiment there was a group of cows that were machine milked twice daily from calving. Milk production from sucked cows was greater during the suckling period than from machine-milked cows in the same period, but in no case was there any significant difference between suckling treatments. Increases in production during the 8-week suckling period ranged from 7.1 (P > 0.05) to 19.4% (P< 0.05), or from 75-21 8 kg. The extra milk produced by the cows sucked once daily went to the calves, and similar (P > 0.05) quantities or significantly less milk (P< 0.05) was produced at the alternate machine milkings compared with non-sucked cows in the same period. Regardless of suckling treatment in early lactation, the cows failed to show any carryover benefit. Lactation length and liveweight change in cows was unaffected by suckling treatment. The interval of post-partum anoestrus increased by about 6 days for each additional week of suckling. The average increase due to 8 weeks suckling in the four experiments ranged from 41-66 days. Teat damage increased with duration of twice-daily suckling, but had no effect on yields after sucking stopped. Teat damage of cows sucked once or twice daily to 8 weeks was similar. The incidence of mastitis was low in both sucked and machine-milked cows, and was not related to suckling treatment. Multiple sucking of Friesian cows in early lactation is a means of obtaining more milk from individual cows without incurring penalties in liveweight and body condition loss; it has no effect on post-weaning milk production.

Black Bengal Goat

The experiment was aimed to investigate and compare the growth, milk production and reproductive performances of Black Bengal goat under semi-intensive production (IP) and scavenging production (SP) system. Six Black Bengal does were assigned into 2 treatment (IP and SP) having 3 in each group. The IP group was allowed to graze six hours daily and supplemented with concentrate (soybean meal and wheat bran) and roughage (sorghum and common grass) and the SP group was maintained by the rural landless farmer traditionally as scavenging system. The average birth weight of kids were 1.30 and 0.96 kg for IP and SP systems, respectively and varied significantly (P<0.01). The birth weight of male kids were significantly (P<0.01) higher than that of the female kids. Pre-weaning gain was also significantly (P<0.01) higher in IP than sp system. In both the systems, male kids always showed higher gain than that of females. The kids were weaned at an average age of 92 and 81 days for IP and SP systems, respectively. The kids of the IP and SP systems attained at an average weaning weight of 5.43 and 4.17 kg, respectively which differs significantly (P<0.01). Weaning weight was found to be significantly higher in IP than SP systems. Average initial live weight, live weight at kidding and final live weight at post partum heat of does of IP and SP systems were 22.10, 22.61 and 21.03 and 21.90, 22.35 and 19.73 kg, respectively, where there was no significant difference except the final live weight (P<0.05). The average daily milk yield, total lactation yield and lactation length for IP and SP systems were 214 ml, 20.47 l and 95.33 days and 162 ml, 13.75 l and 84.66 days, respectively and varied significantly (P<0.01). Average litter size of the IP and SP systems was 2.00 and 2.33, respectively. Average post partum heat period and kid mortality were significantly (P<0.01) lower in IP than SP system. Gross return was found higher in IP than that of SP systems. Thus, it can be recommended from the present study that the growth rate, weaning age, weaning weight, milk production, post partum heat period and kid mortality of Black Bengal goat could be improved through proper feeding and better husbandry system which was reflected from gross return.

Two experiments were carried out to measure effects of body condition at calving and different levels of feeding after calving on milk and subsequent reproduction.In experiment 1, which was conducted in two consecutive years, 162 cows (77 in year 1 and 85 in year 2) were group feed so as to reach a target body condition (condition scores ranging from 3-6) four weeks before calving. During the last four weeks before calving, all cows were managed so as to maintain their individual condition scores. At calving, cows in similar condition of similar breed and with similar previous milk production were allocated to high and low levels of feeding at pasture for the first five weeks of lactation. Mean pasture intakes were 13.0 and 7.0kg dry matter (DM)/cow.d in year 1 and 15.0 and 8.5 kg DM/cow.d in year 2In experiment 2, 40 cows were offered pasture and hay from 20 weeks before calving to achieve a body condition score of either 4 or 6 by two weeks before calving. During the first five weeks of lactation, cows were individually fed in stalls on freshly cut pasture at one of three levels of intake, 7 or 10 kg DM/cow.d or .In both experiments cows were grazed as one group from week 6 to 20 of lactation.Improved body condition at calving resulted in an extra 4.0, 11.0 and 7.4 kg milk fat per unit condition score over 20 weeks of lactation, for year 1 and 2 of experiment 1, and experiment 2, respectively. Cows in poorer condition partitioned a higher proportion of feed energy to liveweight at the expense of milk production than did the cows in better condition. However, increasing the plane of nutrition in early lactation resulted in higher levels of milk production and reduced the need for cows to mobilize bodyreserves. Improved body condition at calving had a positive effect on milk fat percentage, particularly in early lactation, but did not affect milk protein percentage. Input-output relations calculated from the experimental data showed that the benefit sf to improve body condition before calving was less than that of additional feeding after calvin changes in the condition of the cows were taken into consideration (25.8 vs 1 4.6 kg DM to yi kilogram of milkfat). Improvements in condition and feeding in early lactation reduced the anoestrus interval after calving by 5.7 d for each additional condition score at calving and 1. d for each additional kgDM/cow.d fed over weeks 1-5 of lactation. The input-output relations resented will enable farmers to assess the likely consequenes of changes in their feeding management in the crucial peripartum period with a greater degree of confidence than in the past.

Abstract Adequacy of milk production in the newborns will affect the success of exclusive breastfeeding. Not all postpartum mothers are able to increase milk production in the postpartum period. Acupressure at the meridian points is one way to increase milk production in postpartum mothers. This study aims to determine the effect of acupressure therapy on increasing breast milk production in postpartum mothers at PKU Muhamadiyah Bantul. This study was a quantitative study  a quasi-experimental research design with pre-test and post-test nonequivalent control group. The number of respondents in each group was 17 people. The treatment given was acupressure at the meridian points for 5 minutes on days 2 and 3of poatpartum. Breastfeeding adequacy was assessed before treatment and on day 4 postpartum. Data were analyzed by Mc Nemar analysis. The results showed that there was a significant difference in breast milk production before and after acupressure with p value of 0.000 (p value <0.05). There was a significant difference in breast milk production in the control group before and after being given the breastfeeding technique leaflet p value 0.001 (p value <0.05). Conclusion: There is no significant difference in breast milk production after being given acupressure and after being given leaflets about breastfeeding techniques at PKU Muhamadiyah Bantul p value 0.100 (p value> 0.05).  Keywords: acupressure, breast milk production, postpartum

Abstract The objective of this study was to evaluate the milk production, body weight, and body condition score (BCS) of ewes fed with different energy levels. Seventy-one ewes were used and distributed in three treatments according to the metabolizable energy (ME, Mcal/kg) levels in the diet: CTL = according to the NRC (2007) recommendation for each stage (gestation and lactation); PLUS = CTL plus 10% of ME per kilogram of dry matter; LESS = CTL less 10% ME per kilogram of dry matter. Body weight and body condition score were evaluated a week before the expected date of parturition, a week after giving birth, and at weaning (60 days). Dairy production was evaluated at 20, 30, 40, 50 and 60 days after giving birth by the indirect method of the two weighing. The experimental design was analyzed as randomized complete blocks. There were no differences on milk production during almost all the lactation curve. Only on day 50 (P = 0.051), CTL was still at peak, while LESS and PLUS had already decreased their production. However, at 60 days, all treatments were already with low production, justifying weaning in this period. Results of weight and BCS showed a significant difference in all periods evaluates. Ewes in the PLUS diet had greater BW and BCS. The BCS before giving birth is expected to be over 3.5 and treatment LESS was the only one that did not achieve this score (2.66, 3.37, 3.83 for LESS, CTL, and PLUS, respectively). At weaning, ewes fed PLUS and CTL had BCS of 3.51 and 2.92, respectively, but treatment LESS had only 1.82. That is prejudicial for the next mating seasonal and this animal. We concluded that LESS diet interfered with the body reserves of sheep.

The interval from calving to first oestrus (post-partum interval) is an important determinant of reproductive efficiency in suckler cows. While this interval is influenced by a range of factors including cow age, breed, presence of bull, cow-calf interactions and disease, the most important factors are suckling (frequency / number of calves) and nutrition (pre- and post-partum nutrient intake, body condition at calving and during early lactation). The mechanisms by which these factors, either independently or interactively, affect the length of the anoestrous period are unclear. Similarly, the time post-partum at which suckling exerts its effect on resumption of cyclicity is unknown. The effects of body condition score at calving and of changing the frequency of suckling on the length of the post-partum interval were determined. Preliminary results are presented.

Abstract This study assessed daily milk yield (DMY), 100-day (MY100), and 305-day (MY305) milk yield, and lactation length (LL) in purebred Ankole cattle and Ankole crossbreds, and the influence of environmental factors on these traits. Milk yield data were obtained for 865 cows and 1234 lactations and analyzed using a mixed linear model. The overall least squares mean of DMY, MY100, and MY305 across breed groups was 2.7 L (N = 1234, SD = 1.7), 262 L (N = 959, SD = 176), and 759 L (N = 448, SD = 439), respectively, while the average lactation length was 256 days (N = 960, SD = 122). All factors included (breed group, season and year of calving, and parity) were significant for yield traits, except season of calving for MY305. First-parity cows had the lowest milk production, and fourth-parity cows the highest. For all traits, pure Ankole cows had the lowest milk yield. Among the crossbreds, there was no significant difference between Ankole × Friesian, Ankole-Jersey mother × Sahiwal sire, and Ankole-Sahiwal mother × Jersey sire, or between Ankole × Sahiwal and Ankole-Sahiwal mother × Sahiwal sire. It was concluded that Ankole crosses with Friesian or Jersey can be beneficial, even under a management system of limited nutrition as in Rwanda.

Two herds, each of 19 Friesian cows, were run on separate farmlets in north-western Tasmania. One herd (NW) grazed pasture only, and was estimated to be receiving 75% of potential intake, while the second herd (W) received 3.0 kg coarsely hammermilled wheat per cow, daily for 42 days during early lactation in addition to pasture. Although the feeding of wheat increased total feed intake, there was no significant difference between the groups in either daily milk yield (21.5 v. 21.8 L cow-1), milk fat yield (1.1 v. 1.09 kg cow-1), liveweight change (0.05 v. -0.2 kg cow-l) and herbage intake (12.0 v. 12.0 kg DM cow-1 day-1) of cows or of pre- (1.77 v. 1.8 t DM ha-1) and post- (1.31 v. 1.32 t DM ha-1) grazing mass, on farmlets NW and W respectively. We conclude that the feeding of wheat did not increase milk production or improve liveweight change under the conditions of this experiment.

Body Concentration

Body condition of lactating dairy cows varies at different stages of lactation. Cows usually mobilise their body reserves to provide energy and protein for milk production in early lactation, and gain weight to deposit energy and protein for pregnancy at a later stage. The objective of the present study was to examine relationships between body condition score (CS) and body concentration of lipid, CP and energy.

Friesian Cows

SUMMARYOver the 4 years 1965–8, a total of 105 mature Friesian cows and 84 Friesian heifers were fed various levels of nutrition at two stages of the lactation to study the effect on milk production. The experiments were carried out over a whole lactation at four Experimental Husbandry Farms, Boxworth, Bridget's, Great House and Trawsgoed. There were three treatment levels in early lactation (weeks 3–10) comprising 5·9, 7·8 or 9·8 kg D.M./day of concentrates for mature cows and 1·6 kg D.M./day less at each level for the heifers. In mid-lactation (weeks 12–18) the two lower levels of concentrates were fed arranged factorially with early-lactation levels. A basal forage ration usually of hay was fed to provide 85% of the basal maintenance requirements. During the remainder of the lactation all animals received the same level of nutrition. In addition to the pre-determined feed treatments, one further group of animals in each block was fed according to the milk production in the preceding week.Overall an increase in level of nutrition in early lactation produced a regular increase in milk production from successive increments with adult cows but only for the first increment with heifers. Raising feed level in mid-lactation increased milk production for all animals. There were considerable residual effects from early-lactation feeding but these were less with mid-lactation feeding. These same effects were also noted with yields of solids-not-fat and to a less extent in milk fat production.The experimental results indicated not only the mean effects of treatments but more important the interaction with individual animals. Study of the response of individual animals indicated that the effects of level of feeding varied in proportion to the potential of the cow. The presentation of mean results can therefore be misleading. The potential of a cow was indicated by milk production in the immediate post-calving period. This period could be used both in experimental designs for selecting animals in the allocation to experimental treatments and also in the practical context for rationing individuals or groups of cattle.The absolute plane of nutrition related to the potential of the animal was the most important factor in determining the efficiency of utilization of feed for milk production.
